In this conversation, Neil interviews Dimitris Katsanis, one of the world leading experts in bike design. They discuss the UCI regulations that govern bike design for road and track racing. Dimitris explains the evolution of bike design and the role of carbon fiber and titanium in creating lightweight and aerodynamic bikes. He also talks about his collaboration with Pinarello and the development of the Dogma F8 and F10 bikes. Dimitris emphasizes the importance of balancing weight, stiffness, and aerodynamics in bike design and the ongoing pursuit of improvement in the field. In this part of the conversation, Dimitris Katsanis discusses the evolution of bike design, the importance of aerodynamics and system drag reduction, the differences between track and road bike design, the interactions between the bike and rider, the impact of weight and aerodynamics in solo breakaways, the ongoing weight vs. aero debate, the role of stiffness in bike design, the relationship between stiffness and comfort in bike frames, and the potential of 3D printing and additive manufacturing in bike manufacturing. In this conversation, we also discuss the limitations of carbon fiber in bike design and the potential of 3D printing to overcome these limitations. He explains how 3D printing allows for the creation of custom shapes and internal structures that can improve the performance and weight of bike components. Katsanis shares examples of 3D printed handlebars and frames that are lighter than their carbon fiber counterparts. He also discusses the future of mass customization in bike design and the impact of regulations on innovation. Finally, he speculates on what bikes may look like in the future if design restrictions were lifted.Chapters06:40 Introduction and Background11:10 UCI Regulations and Bike Design17:48 Evolution of Bike Design and UCI Regulations25:27 Influence of Weight and Aerodynamics on Bike Performance32:01 Pushing the Limits of Aerodynamics37:16 Yaw Sensitivity and Aerofoil Sections40:53 Continual Improvement in Bike Design42:25 The Evolution of Bike Design42:51 Aerodynamics and System Drag Reduction44:21 Track vs. Road Bike Design47:05 Interactions Between Bike and Rider48:02 The Importance of Aero in Solo Breakaways53:00 Weight vs. Aero Debate56:00 The Impact of Weight on Performance58:04 The Role of Stiffness in Bike Design01:04:01 Stiffness and Comfort in Bike Frames01:11:56 Materials in Bike Design: Steel, Aluminum, Titanium, and Carbon Fiber01:18:08 The Potential of 3D Printing and Additive Manufacturing01:19:45 The Limitations of Carbon Fiber01:21:41 The Potential of 3D Printing01:24:10 The Surprising Lightness of 3D Printed Titanium01:28:02 The Future of Mass Customization01:34:06 The Impact of Regulations on Bike Design01:43:09 Speculating on the Bike of the Future
Introduction This is a follow up episode on Home Assistant (HA), see hpr4099 :: An introduction to Home Assistant (HA) for an explanation of what Home Assistant (HA) is, and why you might want to install it. The Home Assistant Installation page offers several different install methods, listed along with the level of difficulty. Easiest: Plug and play with Home Assistant Green Easy: DIY with Raspberry Pi Intermediate: Extend with Home Assistant Yellow Hard: Install on other hardware Expert: Advanced installation methods Today we will be installing Home Assistant Operating System (HAOS), on a x86-64 machine. Home Assistant can be repurposed and installed on various hardware, such as an Odroid or a generic x86-64 machine. The Home Assistant Operating System allows you to install Home Assistant on these devices even if you have little to no Linux experience. We are going to my HP t610 Flexible Thin Client, which has a 16GB SATA Flash Drive, and I upgraded it to 16G of Ram. Note that this will install Home Assistant Operating System (HAOS) as a computer appliance. That means that it will run a bare OS with the various components in a customised docker setup. It will take over the entire computer, and requires secure boot to be disabled. On the HP t610 Flexible Thin Client, that involves pressing "Esc" at boot to get to the bootup menu. If that doesn't work try pressing "F10" just after turning on the power. Two methods to install HAOS has no integrated installer like you would expect with distro hopping, but it requires that the image be burned directly onto the disk of the computer itself. It has two methods to do this and "Method 2: Installing HAOS directly from a boot medium", is basically take the disk out of the target system and attach it to your own computer. The use a burning tool like Balena Etcher, or dd to write the image to disk. Much as you would burn a sdcard for a raspberry pi. I don't have a way to do this so let's go with method 1. Method 1: Installing HAOS via Ubuntu booting from a USB flash drive Here you download and burn live operating system as you would if you were distro hopping, the document suggests to use Ubuntu. I tried it but my HP t610 Flexible Thin Client didn't like it. It also didn't like Fedora despite having worked earlier, so I just used Debian LXQT. https://www.debian.org/download https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/debian-live-12.5.0-amd64-lxqt.iso Now you have Debian running off a usb stick on your target machine. Steps to burn Home Assistant Operating System (HAOS) to disk on target Anything after the '#' character is a comment and doesn't need to be typed. Note The following steps are optional, and you should only do them if you wish to ssh to the target machine from your pc. # Anything after the '#' charachter is a comment and doesn't need to be typed. apt install openssh-server # Install the ssh server on the target systemctl start ssh # Start it once installed passwd user # Change the password or you can just use the default which is `live` ip add # Get the IP address of the target ssh user@ip.of.the.computer # Replace ip.of.the.computer with the actual ip address in the step above Open a terminal on the machine, and type the su - commands to get root access on the Debian OS running from the usb drive on the target machine. user@debian:~$ su - Password: root@debian:~# Now you are root, the super user admin, you can install the wget command using the Debian apt package manager. root@debian:~# apt install wget Once wget is installed, we can use it to download the latest image from the HAOS Download Page, which is haos_generic-x86-64-12.1.img.xz at time of writing. root@debian:~# wget https://github.com/home-assistant/operating-system/releases/download/12.1/haos_generic-x86-64-12.1.img.xz Now we have the image we are going to write to the disk, but the question is which disk to write it to. Your target PC will be different to mine but the tool lsblk is good for showing what is installed and mounted. root@debian:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS loop0 7:0 0 2.5G 1 loop /usr/lib/live/mount/rootfs/filesystem.squashfs /run/live/rootfs/filesystem.squashfs sda 8:0 0 14.9G 0 disk ├─sda1 8:1 0 1M 0 part ├─sda2 8:2 0 1G 0 part └─sda3 8:3 0 13.9G 0 part sdb 8:16 1 58.6G 0 disk ├─sdb1 8:17 1 3G 0 part /usr/lib/live/mount/medium │ /run/live/medium └─sdb2 8:18 1 5M 0 part The loop0 is the mount where Debian is running from, while the mounted sdb1 and sdb2 have the word live telling us that's the actual USB drive we installed Debian on to. While your disk will be different, for me the disk to install it on is sda. The partitions sda1, sda2, and sda3 are left overs from a previous install. They will be overwritten anyway. The drive I will be targeting is therefore known to the system as /dev/sda The dd command will do a disk duplication and writes the ones and zeros from the if input file, to the of output file. The command below will take a while and not display anything root@debian:~# dd if=haos_generic-x86-64-12.1.img.xz of=/dev/sda 761949+1 records in 761949+1 records out 390118272 bytes (390 MB, 372 MiB) copied, 66.3225 s, 5.9 MB/s Plug in an Ethernet cable that is connected to the network. Power the system on. If you have a screen connected to the Generic x86-64 system, after a minute or so the Home Assistant welcome banner will appear in the console. In the browser of your desktop system, within a few minutes you will be able to reach your new Home Assistant at homeassistant.local:8123.

Kier Scott of Herding East Stock Dogs outside of Airdrie, Alberta has paved himself a path in the stock dog industry. Growing up around working dogs he didn't get the itch until he found a dog named Sweep from his father. It didn't take them long and they were winning trails and Kier was full steam ahead. Kier and his wife Samantha now host weekly dog nights, clinics, dog sales and a winter series dog trial at Thorlakson arena. You can follow Herding East on Facebook or look at their website where you'll see the, Diamond T Cowhorses sponsored, weekly blogs on stockdog training and philosophies.We truly appreciate Kier and Samantha, they have been huge supporters of our podcast and this episode was a true pleasure to produce. ✨Sponsor✨F10 Ultra Saddle padsLike most people, I've been on the hunt for a high quality saddle pad that is going to fit all types of horses as well as look good and perform under all conditions.When I was fortunate enough to win cowboy of the day award at a ranch rodeo this fall I was awarded an F10 ultra pad.I was ecstatic because I was in desperate need of a new pad but it wasn't until after I talked to Dillon at F10 Ultra that I realized what I got my hands on.They use nothing but the best, sourcing their wool from %100 merino sheep here in Alberta.F10 rated wool has the highest compression rating and tensile strength rating on the market. This makes it an easy choice for you and your equine partner. I have been on a long journey to find a pad of this quality and happy to say I stand behind F10 Ultra fine saddle pads.

Avsnitt 404 av Tyngre Träningssnack och vi diskuterar tre lyssnarfrågor. Först blir det en diskussion kring om det finns någon gräns i kilo där knäna inte längre klarar av belastningen vid löpning och man får ont. Sen diskuterar vi betydelsen av att inta energi och framför allt kolhydrater under riktigt långa träningspass eller lopp. Hur stor roll spelar det i fall man ändå upplever att prestationen blir okej och du kan hålla samma intensitet hela tiden? Till sist blir det en längre diskussion kring olika zoner, intervaller och hur luddiga gränserna egentligen är mellan de olika nivåer/zoner som man ofta delar inte träningsintensitet i. På Tyngre Träningssnacks instagram kan du hitta bilder relaterat till detta och tidigare avsnitt. Hålltider (00:00:00) Gudiol har försökt att jobba på jumpyard medan barnen hoppar (00:04:44) Jacob tycker att det är riktigt kul att träna F10 lag i fotboll (00:06:49) Jacobs dotter började gråta när han skulle vara pedagogisk (00:12:39) Finns det en maxbelastning för knäna där du nästan direkt får ont? (00:17:53) Jacob tror vi har en maxgräns för hur mycket vi kan anpassa oss även över tid (00:30:25) Varför det finns ventilhattar på cykelslangar - Nu har vi svaret! (00:31:29) Hur lite kan man äta vid väldigt långa sträckor cykling och ändå prestera okej (00:44:08) Varför springa tröskelintervaller på 6 minuter när 30 minuter i rad känns okej?
I hate to break it to you, but yes - what your grandmother did directly influences how your DNA is regulated today. This is called epigenetic transgenerational inheritance. Epigenetic transgenerational inheritance refers to the transmission of epigenetic marks from one generation to the next. This phenomenon can occur through the germline and affect the development and health of future generations.To further explain, it is possible for environmental factors that affected our grandmother to influence our epigenetics through epigenetic transgenerational inheritance. For example, if our grandmother was exposed to a toxin that caused changes in her epigenetic marks, those changes could be passed down to subsequent generations. This could lead to an increased risk of disease or other health conditions in her grandchildren, even if they were not directly exposed to the toxin themselves.Additionally, lifestyle choices such as diet and exercise habits can also have epigenetic effects that can be inherited. If your grandmother had a poor diet or was sedentary, for example, this could have altered her epigenetic marks and potentially contributed to a higher risk of obesity or other metabolic disorders in her grandchildren.In this week's Everything Epigenetics podcast, Dr. Michael Skinner speaks with me about just that - epigenetic transgenerational inheritance, a term he coined in 2005. We discuss how Dr. Skinner and his team have shown that exposure to certain environmental factors, such as chemicals, nutrition, and stress, can cause changes in the epigenome that can be passed down through multiple generations. Dr. Skinner and I also chat about the mechanisms underlying this transgenerational epigenetic inheritance and the implications for human health and disease, including developmental disorders, obesity, and reproductive problems.In this episode of Everything Epigenetics, you'll learn about: Dr. Michael Skinner's history and how he became interested in things that cannot be explained by classical geneticsThe history of Epigenetics starting with Conrad Waddington who coined the term “Epigenetics” in 1942Epigenetic mechanism and marks (DNA methylation, histone modifications, chromatin structure, non-coding RNA, RNA methylation, and DNA adenine)How Dr. Skinner discovered epigenetic transgenerational inheritance Epigenetic transgenerational inheritance The role of the germ cell in this type of inheritance The limitations of genetic data in determining phenotypic outcomes Classical examples of epigenetic transgenerational inheritanceGenerational toxicology The work Dr. Skinner is performing now (F10 generations in rats) Environmental toxicants that have been shown to be associated with the transgenerational inheritance of increased disease susceptibilityHow different toxins can have an affect on our health today How other epidemiological factors can promote a transgenerational effect How Dr. Skinner's work has changed his own lifestyle Using epigenetic biomarkers for preventative therapeutic strategies to detect disease early The limitations of government policies regulating toxicant exposure The best way to move forward using epigenetics in the healthcare industryDr. Skinner's most recent work (which had over 500+ million reaches) looking at epigenetics in twins with different workout regimens How epigenetics can predict preeclampsia, preterm birth, male infertility, and moreThe lack of funding in this area of science Support the showThank you for joining us at the Everything Epigenetics Podcast and remember you have control over your Epigenetics, so tune in next time to learn more about how.

In this podcast, we discuss HSE's latest construction initiative focusing on the risks of injuries and aches, pain and discomfort in joints, muscles and bones known as musculoskeletal disorders (MSDs). With 40,000 construction workers reporting that they suffered with MSDs last year, Matt Birtles, Principal Ergonomics and Human Factors Consultant at HSE and Peter Crosland, National Civil Engineering Director at CECA discuss what the industry can do to promote change and protect its workforce. Amongst other things, the podcast covers HSE's ‘Your health. Your future' construction campaign, the impact that these injuries can have on workers and employers legal responsibilities and the sensible control measures that can be introduced regardless of the size of the construction site. For more information on the campaign visit ‘Your health. Your future' PODCAST TRANSCRIPT [00:00:00] Mick Ord (Host): A warm welcome to you whenever you are listening to this Health and Safety Executive podcast from me, Mick Ord, and our soon to be announced guest experts. This podcast will be the first in a series designed to help you to make your life a little easier, both in work and maybe even spilling over into your personal life, you never know. The health and Safety executive is committed to improving the health and wellbeing of workers in Great Britain. And today we'll be focusing on the construction sector, a key industry that employs more than two million people and includes employers and building workers, contractors and subcontractors, staff and freelancers alike in a range of organisations from sole traders to multinationals. Last year did the UK alone, 40,000 construction workers suffered from injuries and aches, pain and discomfort in joints, muscles and bones. Such injuries can have a serious impact on their ability to perform tasks, their quality of life, and in some cases their ability to stay in work and earn a living or having to take time off work as well. Many people suffer from long term pain and discomfort as a result of injuries sustained on building sites. So with such worrying stats in mind, the HSE are embarking on the Work Right construction campaign. This means that HSE inspectors will be performing a thousand inspections at building sites in the UK. So what will they be expecting from companies? Joining us is Matt Birtles, an ergonomics expert from the HSE Science Division, and a little later we'll be hearing from Peter Crosland, the National Civil Engineering Director at Ceca, the Civil Engineering Contractors Association. Well, first of all, Matt, thanks for joining us for the podcast. What should companies expect if an inspector does visit their site? [00:02:18] Matt Birtles: First and foremost, thank you Mick for hosting us and having us on this podcast. When an inspector comes knocking on site, first and foremost, expect the norm. So they'll be looking at safety as well as health issues. But what's happening during the campaign especially is there'll be an increased focus on particularly the kinds of risk factors associated with musculoskeletal disorders. So there's been an awful lot of effort ahead of this campaign within, you know, my regulatory colleagues in HSE to train them upon understanding the key risk factors. For musculoskeletal disorders, how to assess them and what kind of controls they might want to see in place. And so when the inspector does come, they'll be looking at the kinds of manual handling activities and maybe some repetitive work that commonly go on in construction sites and looking specifically at ways in which the risks are controlled. So there may be some of that manual handling activity happening during the inspection, and they'll just observe that and watch how it's done, where potentially improvements could be made. And also looking at the paperwork and the risk management system. If there aren't any manual handling operations happening at the time of the inspection, they're just more likely to ask principal contractors or ask them on site responsible for safety about manual handling, and ask them to show them their risk management systems, any risk assessments they have, any planned risk controls. Especially at those points where you'd expect increased manual handling. So moving materials around during deliveries, for example, during fitting or moving plant equipment. And so just an increased focus on musculoskeletal disorders in every inspection for the next six weeks or so. [00:03:57] Mick Ord (Host): And who specifically is the "Your Health, Your Future" campaign aimed at? [00:04:02] Matt Birtles: The target really is anybody involved in construction. And so while obviously anybody on the site, you're more likely to see colleague inspectors or regulatory colleagues, we'll be looking at those involved in the design and then planning of construction, and procurement, for example, and then certainly those on the managing sites and working on sites and doing the physical tasks on sites. And it's aimed at larger construction sites or smaller. And so we're going to try and focus on as many sites as we possibly can and as greater variance as possible. But everybody has responsibility for helping to manage MSDS or musculoskeletal disorders. [00:04:43] Mick Ord (Host): And why the focus now on the manual handling assessment? [00:04:48] Matt Birtles: Well, manual handling assessment. It's gotten easier over the years with the advent of the HSE tools like the MAC tool or manual handling assessment charts or the RAPP tool risk assessment for pushing and pulling. For, you know, barrows and the like, Manual handling assessment has gotten much easier. And while doing the assessment using the tile method or L23 method, it meant all the methods involved a checklist of looking at all the different risk factors. It could be quite arduous and not necessarily give you the answers that would lead neatly to potential solutions. Now, with the MAC tool, which is not new, there's nothing new in the MAC tool per se. It's much easier to actually do a quick assessment and wherever identifying manual handling operations. It's very quick and easy now – even using the online version, which is the new element of all this I suppose – to do a quick assessment and understand the key risks and level of risk. And so the barriers have gone for potentially, arguably, long and arduous risk assessments. It's now very straightforward to do a risk assessment, and so it shouldn't be a barrier anymore. [00:05:54] Mick Ord (Host): And how serious is the problem of injuries sustained in moving and handling construction materials? [00:05:59] Matt Birtles: Inevitably being who I am, where I'm from, I'm going to say very. But actually the stats do add up. As you mentioned, 40,000 injuries per year on average in the construction sector. But if you compare that to other industries or the rest of all industry, you've kind of almost got double the rates of musculoskeletal disorder amongst construction workers. So, while across industry, we might see roughly speaking about 1/100 workers getting injured with musculoskeletal disorder, in construction, it's around 1/50. So about 54% of ill health for the construction sector is musculoskeletal disorders. So it's far too common. It affects far too many lives. Then the other way of looking at how serious it is, is what's the impact on individuals and per individual? What happens to that person, and we may cover this a bit later, but it can affect every aspect of life. Of course, as you mentioned it can impact on your ability to actually go to work and earn a living. But also it can impact on your home activity, mucking around with your kids, the enjoyment you might get from normal stuff like going down the pub, going to the cinema, and those sorts of things. Because of the nature of the discomfort with MSDs, it can actually affect your ability to stand and make that uncomfortable, but also your ability to sit down and make that uncomfortable. So in those sorts of areas, it becomes very serious because it can really deeply impact on people's health and wellbeing, not just in work, but also outside of work. [00:07:28] Mick Ord (Host): Peter Crosland from Ceca, Peter, have you got some examples of the kind of injuries that workers have sustained and the actual impact it's had on their lives? [00:07:38] Peter Crosland: Well, yes. Thanks Mick. And I think yes, all too often where you get examples of people who have worked in the industry for a long time and then suddenly become unable to work. And coincidentally, I was at a meeting this morning up in the northeast where one of the previous site supervisors had worked for 20 years laying curbs. And actually had a back that was quite wrecked and he really was in a quite a difficult place. And I think we just hear that story all too often. So one of the problems has been the latency effect of all these issues coming to the surface, and I have to say that given the nature of our workforce, which is, I think we'll all know that demographics by now, they've been banded around. You know, many times that there are a cohort of people who have carried out those activities and are now suffering really quite badly, and they're having to move jobs. They're having to step down away from the work that they really, you know, they joined the industry to do and they can no longer carry out those functions. And as Matt says, that then starts to spill over into home life and it affects the quality of life of not only the worker, but also the family. [00:08:57] Mick Ord (Host): And in that particular example that you just quoted from the northeast, is there anything that you can do to help that particular person if they've been manual handling in a certain way for 20 or so years? [00:09:10] Peter Crosland: This is probably going to sound slightly negative, but I think sometimes we are a little bit reactive in the industry rather than proactive. Unfortunately, you have a whole host of workers who have operated in a slightly cavalier manner. Perhaps they didn't know better. And then as we have known, and certainly Matt's team have discovered through the statistics, that actually this is what's happening to the workforce and therefore we need to go and find ways of making sure that that doesn't happen again. And I think you can cite examples right and way throughout all the activities that certainly we were involved in, whereby, you know, we're always looking to see how we can improve matters for every worker. [00:09:55] Mick Ord (Host): Matt, with regard to the HSE visits, will companies being given prior notice or will they just turn up? [00:10:02] Matt Birtles: Generally we'll just turn up, There's not a specific requirement to give a prior notice. It may well be that a site's already got a planned inspection or a meeting with a regulatory colleague, and that will then turn into a musculoskeletal disorders focused inspection. But unless you've got already something planned in the next six weeks with a regulatory colleague, no, expect them to just turn up an announced. [00:10:26] Mick Ord (Host): How are the construction sites chosen beforehand? [00:10:30] Matt Birtles: Well, no sites are exempt, so any site could be visited by a regulatory colleague. Inspectors generally visit sites that are known to be higher risk, and there is some intel on that. There's a number of ways to identifying the sites to visit. The F10 notification database that we have on sites where we've had an instance before, perhaps sites where some concerns have already been brought to our attention through various means or sites, perhaps where they've received RIDDOR accident forms, or they've had RIDDOR reportable accidents in the past that have not previously been selected for investigation. There'll be some channelling with that along with a sort of local intelligence as well. Knowing where the sites are, but the sites, there's no specific requirement or desire to pick just on small or just on larger sites. Any site could be visited to be perfectly honest. [00:11:18] Mick Ord (Host): And what does the law say about what employees need to do to protect their workforce? [00:11:23] Matt Birtles: There are various laws. I suppose the one that's most specific to this campaign is the manual handling operations regulations. It's relatively straightforward, to be honest. In fact, if you ask any of my inspector colleagues – where I'm from in in the agency, it's our privilege to often train them – I imagine most inspector colleagues will say one of three words, and that's AVOID. ASSESS. REDUCE. So the law pertaining to manual handling is avoid hazardous operations. Now, that's important. It doesn't say avoid manual handling anywhere in the law. in fact, good manual handling is actually good for you. It does keep you fit, keep your muscular, and potentially there's research that suggests you may live longer. So don't avoid all manual handling, but avoid hazardous operations wherever you possibly can. But if you can't avoid hazardous manual handling, then we don't immediately, you know. Put in a claim or something. We assess those hazards. We assess the risk using usually the MAC tool and the RAPP tool initially, and that's a five-minute task. It'll take longer to, you know, find it on the website maybe than actually to do an assessment. But I promise you the second assessment, you deal with will take five minutes, and then you assess those tasks to understand the risk in order to reduce the risk. This is where the rubber really hits the road, in terms of risk management. We can have lots of really nice – in terms of the MAC and the RAPP tool – very colourful assessments. But unless they're used to actually challenge the tasks and make those tasks easier to do risk reduction by making the jobs easier, then it's just from the paperwork. So avoid, assess, and reduce risk is what it's all about. [00:12:59] Mick Ord (Host): And Peter, what are the barriers to employers and workers on sites? [00:13:04] Peter Crosland: I, I think there are many barriers, but I think it depends what type of site that you are looking at. What we find within Ceca particularly, we have a very broad church of members. So ranging from tier ones through to SMEs, almost on to solo practitioners in some cases, although they're not direct members because we do have limits on that. But I think one of the barriers will be for those, I would say, down the supply chain to be able to access the information and training that they need to carry out the work properly. So, you know, we've already mentioned the fact that yes, there is a legal requirement and there are others that apply as well. Obviously, you know, not least the ‘74 Health and Safety at Work Act, you know, we have as employers, have a duty of care. So regardless of where those people are in the supply chain, there is somebody responsible for that person. I actually, a bit like Matt, I split the sort of desires into three parts really. There is a sort of like a MUST DO, a SHOULD DO, and a COULD DO.. And that's where the barriers are really, because most do apply the MUST because it is a legal requirement, obviously. There is the SHOULD, which perhaps includes specific training around those lifting requirements that might generate those MSDs. But actually then there's the COULD. You know, what could clients and organisations do to really help the workers make sure that they don't suffer or are made ill through their work? So things like that would be really trying to engage with them, almost a one-to-one, job specific level, to say “Well, look, this is what we've got to do. How do you think we are going to do it?” And I don't think that happens often enough. [00:14:49] Mick Ord (Host): And Matt, what do employers need to know and do now prior to the possible visit? [00:14:56] Matt Birtles: Look at their risk management systems they've got in place. That may be occasionally dusting those off or just making sure that they're up to date. And so that means, you know, looking at the paperwork they've got in terms of a local policy, a local approach to managing musculoskeletal disorders, having a look at the risk assessments that they've already done, and do they still match the tasks? One of the things obviously about construction is they have a changing environment. So do they need updating and do you need to re-challenge some of the work that's done?? It may have changed since the last assessment, and again, I absolutely agree with what Peter just said through engagement with the workers. So obviously the colleagues who are actually doing the work know what's changing in the environment better than any of us. Have a chat with them to make sure that the risk assessments are covering the right tasks in terms of, you know, risk profile or effectively, are they the hardest tasks that the people on the sites would prefer to avoid? If they can, are they looking at the right tasks? And if not, maybe add to the risk assessments. Make sure that you're assessing those tasks that are identified through engagement are the ones that potentially have the greatest level of risk. And then look again at the solutions they've got in place. You know, download those hire catalogues and have a look at what's available and perhaps challenge what is being done. Is there anything that can be done on the sites that would avoid or eliminate some of the heavier activity by putting things on wheels or using mechanical aids? Just sharpen things up. I'm sure you know, the majority of sites have got risk management in place. Just make sure that that's ready because they're the sort of things that the inspector colleagues will be asking for when they do come around. [00:16:38] Mick Ord (Host): And Peter, you've already mentioned that the guidance is relevant to small builders as well as large builders. What about subcontractors? [00:16:46] Peter Crosland: Well, that's even a more difficult to nut to crack, I think. And it's really trying to get that message right throughout the supply chain. So I don't think there's any easy answer to this. We certainly, within Ceca and also working with HSE, it's very difficult to try and get a common message out to all of the industry, and almost by saying that each part of the industry also almost needs a specific message as well. So we do really work quite hard at trying to get the right message to the right people at the right time. And obviously small builders, small organisations are part of that conundrum, if you like. So certainly not an easy answer there, Mick. And I think we're all searching for that holy grail in being able to, as I say, do exactly that – get the right message to the right people at the right time. [00:17:37] Matt Birtles: I concur. That is the challenge, isn't it? Getting the message to the smaller enterprises and the refurb kind of sites is a challenge. While largely the messages are the same for those sites, proportionality and practicability may mean that the kinds of solutions we would expect to see or hope to see under smaller sites would be far less than those on the larger. There's just not enough money washing around to go to the higher companies and get the largest solutions. And so, we have to be quite pragmatic about what we should expect. But the guidance is still relevant. It's just proportionately, we may expect a little bit less in terms of expenditure on, you know, the various solutions that are out there for smaller sites. [00:18:18] Mick Ord (Host): If a company doesn't satisfy the criteria laid out by the inspector, then what are the penalties, Matt? [00:18:23] Matt Birtles: Obviously it depends, and it's still always going to be proportionate to the level of risk. And so, we'd look at the circumstances at each campaign inspection individually. We'll be looking at the relevant standards, the relevant working practices, you know, see how far we are from good practices. For example, using HSE's enforcement management model, which standardises enforcement activity across any sector, anywhere, and looking at the enforcement policy. It could be that, you know, generally speaking for lower-level breaches, verbal advice or perhaps maybe a notice of contravention letter will be used in some circumstances where the gap from good practice or the levels of risk that aren't managed are a bit higher. It could be an improvement notice, and yes, it could be a prohibition notice where there's a more significant risk involved. So we would expect it to be, you know, across the range of potential enforcements, but as far as I'm aware, there's not a target to, you know, suddenly increase the number of prohibition notices or something to be guided by the risk assessments. [00:19:25] Mick Ord (Host): And will the inspectors be speaking to individual workers on site? [00:19:29] Matt Birtles: Yes. I mean, not to try and catch them out or anything. Not to try and point any fingers or blame at any individual. But a part of risk management is making sure that individuals understand the kinds of risks they're exposed to. And have been, you know, informed about levels of risk of certain tasks, have been informed on how to use safe operation procedures, and that could be how to use plant equipment or mechanical aids, for example. And also being informed about the end of any risk management processes. Once we've fixed everything we can through mechanical means and engineering risk out, we'll always have some residual risk at the end that we mop up with training. And so just to find out how well the trainings worked, the manual handing training, for example: has it landed? Has it been successful? Has it changed behaviour? We'd find that out from talking to individuals on site, not trying to pick upon the individual or point a finger and blame anybody, but just to get the general picture of how risk is managed on that side. There certainly could be, yeah. [00:20:30] Mick Ord (Host): And is there anything in particular that individual workers will be expected to know? [00:20:37] Matt Birtles: Yes. I think in terms of risk communication, the kinds of risk factors that they're exposed on site, or the key risk, the higher risk activities, what they may be and how they should accommodate them through RAMS or through safe operating procedures. We would expect anybody on site to know who they need to speak to, if they see any issues that concern for near miss reporting, or for, you know, just reporting potentially hazardous activity, which can happen. We all humans make errors, and we always see something a bit wrong. Where would we go to report that and what would the expectations be on any site? And then yeah, absolutely. The general health and safety training in manual handling training, for example. God forbid they are quoting HSE sentences that we use. We've taken a lot of the words that are given in manual handling training and made them far less fun. So we certainly wouldn't be an examination – "can you quote our particular guidance?" But the general kind of approach to practices. You know, when was the last time that they were sort of reminded of those approaches and did it land? Those are the kind of things we do want people to know about so that they are empowered, as Peter mentioned, for that level of engagement's important. And that's kind of what we're looking at there to make sure that that side of engagement's happening successfully. [00:21:57] Mick Ord (Host): And how will you know if the campaign has been a success? How will you measure its success? [00:22:03] Matt Birtles: Well, this is the first year of a multi-year campaign targeting ill health in construction. So we'll measure the impact of this campaign using the information gathered by inspectors while they're on site. Things like material breach rates or the number of inspections that leads to finding material breaches will be one metric. And then others regarding awareness and behaviour change, as best we can, based on observation. How many sites do we leave having made an immediate impact or a subsequent impact in terms of behaviour changes? But because this is the first campaign in the sector targeting MSDs in quite a while, one of the core objectives of this whole campaign is to provide a detailed knowledge of the state of play across the sector to allow HSE to adapt its approach in subsequent years on how best to support employers and protect workers in the construction industry. So, A lot of the work is going to be about what was effective and that's going to really channel our efforts in future years as we run the next year of the campaign. [00:23:06] Mick Ord (Host): And I guess that's something that you would echo as well, Peter Crosland? [00:23:10] Peter Crosland: Absolutely. We can't solve the issue of MSDs in in one fell swoop. As Matt says, it's an ongoing process. MSD issues have taken a long time to surface. Hopefully it won't take us long to resolve, but as we become more aware of the issues and also I think particularly, not to miss out on the fact that we're becoming aware of workers' presenteeism. So even if they are actually suffering with an MSD, because of the financial crisis that we're running through and have been running through for a while, you know, people feel compelled to go to work. So they're forcing themselves to work when they're not actually maybe running at 90%. So we need to keep on top of MSDs and certainly as Matt outlined right at the start, we did some work about five years ago to try and identify the financial cost of MSDs In terms of ill health to the industry. And we worked out, it was round about the 75% mark. So, you know, when you then compare it to the likes of occupational asthma, silicosis, asbestosis, occupational dermatitis, noise induced hearing loss, etcetera, MSDs are simply huge. So it really is. And I'm pleased to hear what Matt said, that it is part of an ongoing campaign that will be repeated on a regular basis. [00:24:31] Mick Ord (Host): Well look, gentlemen, thanks your lot for that. Anyone listening needs to go onto the HSE site, don't they, if they want a little bit more information about the tools that are available for them and all the stuff you've spoken about. So Peter Crosland from Ceca and Matt Birtles from the HSE Science Division, many, many thanks for joining us on the HSE podcast. [00:24:53] Matt Birtles: Thanks very much indeed. [00:24:55] Peter Crosland: Yeah, thank you Mick.

欢迎收听雪球和喜马拉雅联合出品的财经有深度，雪球，国内领先的集投资交流交易一体的综合财富管理平台，聪明的投资者都在这里。听众朋友们大家好，我是主播匪石-34，今天分享的内容名字叫关于价值投资是否择时的分析思考，来自财先生123。前天和几个朋友泡茶，谈到价值投资，说实话身边做价值投资的人真的很少，大多所谓的价值投资都是不看财报、不分析商业模式，一般都是看个F10数据，看几篇文章推荐买入的基本面投资者。聊天时，几个朋友的观点就是中国不适合价值投资、没有价值投资的土壤，并举了近期某医药、保险等公司股价腰斩的例子，来作为佐证，表示中国股市不适合长期持有。其实，挺能理解他们的想法，在波动性极大的中国股市，如果在高位不卖，股价腰斩是很经常出现的，这样上上下下的过山车，说实话，真没多少人能做到长线持有。传统意义上大多数人理解的价值投资，就是长线持有，通过死扛波动穿越牛熊，并举巴菲特说的“如果你不想持有股票十年，就不要持有十分钟”，以及“买入伟大的公司，永远持有”来说明价值投资不需要择时，只需要长期持有。其实，这个理解很片面，价值投资的本质其实是企业价值的兑现。企业价值可以从低估到合理，企业价值也可以随着企业的成长而成长，而为什么大多数企业需要长期持有，是因为很多企业的价值兑现，需要长时间。而不是说因为长期持有，就能享受到股价提升，这两个本质上是有区别的，价值投资≠长期持有。那么价值投资是否需要择时呢？企业价值的兑现，本质就是一种择时，判断一家企业低估而买入，等到估值合理或偏高再卖出。其衍生出的投资方式以及策略，基本都是以择时来进行操作，如：烟蒂股投资、困境反转、事件套利等等，甚至短线中的热点题材炒作，很多也是含有一部分价值兑现成分（政策、事件导致某个行业或者公司内在价值急剧提升，导致股价随之暴涨）。巴菲特说的错了吗？作为巴菲特的忠实簇拥，我非常认可巴菲特说的话。“伟大的企业，不需要择时”，为什么这样说呢？这边最重要的条件就是“伟大的企业”。什么是伟大的企业，我们不谈什么改变世界之类这种空话，最简单的判断标准就是股价能够翻很多倍，如可口可乐100年翻了50万倍。有人说那还是可以择时呀，高估了卖出、低估了再买不是可以赚更多。对于这个问题，有一种回答是说“无法判断什么是高估、什么是低估，导致无法择时”，我认为对于波动这么大的中国股市，高估低估是很容易判断出来的，不择时不是因为判断不出高估低估，而是以下几个原因：一、长期来看，没必要对于伟大的企业，拉长时间看，短期的波动就如同一个小浪花；举个例子，房价从每平2000元涨到4000元，当时觉得高估卖出后，3000元再买回来。当时来看，是个很成功的择时操作，但现在房价升到了每平5万，那么当年4000元和3000元买又有多大区别呢？所以说，越伟大的企业，择时的效果越差。二、卖出后，买不回来买不回来，倒不是指卖出后股票继续涨而买不回来。这边我举个例子，著名投资者唐朝，一直将茅台认为是伟大的企业，2021年因判断高估将茅台清仓，卖完后茅台就开始大幅回调，但截至目前，唐朝茅台的仓位仍还未达到卖出前的仓位，主要原因就是卖出后持有现金，看到其他有诱惑性的机会就进场了，尤其是在大幅回调遍地是黄金的时候，极其容易捡了芝麻丢了西瓜。就像一个故事，某个北京人发现一个商机，将房子卖了去创业，几年后赚钱回来，确发现连房子的一半都买不起了。对于价值投资来讲，择时是一直存在的，不择时也是因为对于伟大企业，宁愿过山车式的硬抗波动也不愿意承担择时出错的后果。所以，投资者在买入股票时，就得先了解购买企业初衷，是因为低估而买入，还是因为未来可能成为伟大企业而买入，从而对是否择时进行判断。同时，对于长期持有，不惧波动，很多人认为这是逆人性，需要大毅力者才能做到。其实，人性是没那么好逆的，最主要是靠提升对持有企业的认知，是靠投机思维向股权思维方式的转变，而不是仅仅靠毅力就能做到的。

Heat is the longest movie we've watched in a long time for the podcast, so our episode is also the longest one we've done in a long time. Joe shares a celebrity encounter before we have a spoiler-filled conversation about Season 1 of Severance (15:30 to 24:40) and get reminded that we know exactly where Han was during 1F1F. We wonder who Brie Larson could play in F10 and reveal the results of our first Patreon heist poll. We chat about the newest episode of Young Rock (Season 2, Episode 5) (54:05) then find ourselves scratching our heads about Carter Verone in the 2F2F Minute (1:02:10). At long last, we get to Heat (1:12:40) and discuss whether it fits the typical "structure" of a heist movie as well as the evolution of Al Pacino's career (re: making noises on screen). We nominate our heist crew, talk about Racer Trash's heat.wav (which you can download here), and wonder: how the hell did Amy Brenneman's character afford that house?!

Vou disponibilizar a súmula do jogo. 3 pontos importantes e vamos ter calma com tudo. Ganhar é bom demais, alegra para o dia do torcedor e que você comemore a vitória do seu time do jeito que quiser, com os cuidados e responsabilidades adequados, pode fazer o que quiser. | | Link: Súmula da partida: http://sge.esumula.com.br/sumulas/Sumula_Jogo_35638_F10.pdf | Link do vídeo com os melhores momentos do jogo: Melhores momentos do jogo: https://www.youtube.com/watch?v=JWR8UzEPt6E&ab_channel=CentraldoFutebol Zona Mista do jogo contra o Democrata-GV (vídeo do canal do clube): https://www.youtube.com/watch?v=362XqMsrHiw&ab_channel=CruzeiroEsporteClube Gol do jogo: https://www.youtube.com/watch?v=tvFanNDrtvc&ab_channel=CruzeiroEsporteClube E ai, curtiu o episódio?

We're headed back to the streets of Tokyo -- this time with Aaron Neuwirth (Out Now with Aaron and Abe, We Live Entertainment) -- to figure out where Elle, Jakob, and Mr. Nobody were during The Fast and the Furious: Tokyo Drift! We talk about the Dreamcast, Back to the Future, and Possession (1981), preview the F9 director's cut (and rumored F10 title), and watch Monica Fuentes roll up in a delivery truck in the 2 Fast 2 Furious Minute (27:35). Then, we fly across the Pacific with Aaron riding (flying, I guess, I just said fly, why would it be riding) shotgun (is this a thing in planes) for Tokyo Drift (41:45). After reworking a couple of the "lightning round" questions and getting the biggest endorsement for Roman's character that we've ever heard, we dive into Tokyo Drift and hear Aaron compare it to a movie we'd never considered before, but makes perfect sense. We also come up with a new movie to write (that hopefully Brian Rodriguez *of* High School Slumber Party would cover) before spending a lot of time to figure out how The Fast and the Furious: Tokyo Drift fits into the F9 timeline.

欢迎收听雪球和喜马拉雅联合出品的财经有深度，雪球，3500 万投资者在线交流，一起探索投资的智慧，听众朋友们大家好，我是主播匪石-34，今天分享的稿件名字叫做价值vs成长，哪个确定性更强？来自于二马由之。这几天我的文章中在探讨成长与价值的关系，我的观点是无成长则无价值，成长才是最大的价值。看到几位股友回帖，大致表达了这样的意思，他们奉行弱者体系，不太追求成长，喜欢拿一些股息率高的大蓝筹。这样更安全，确定性更强。那么这就涉及一个问题，什么是股票投资的确定性。就我个人而言，我是一个非常保守的投资者，非常注重风控、追求确定性，完完全全的弱化体系践行者。2020、2021这两年，我的投资收益还可以，但这些收益是在我没加任何杠杆，并且平均仓位不满8成的基础获得的。仓位控制从侧面反映了我对确定性的追求。但就持股而言，我认为的确定性和很多人认为的确定性是不同的。首先，我认为90%以上的普通投资者没有能力选择个股，应该去投基金，和普通投资者能力最匹配的投资行为是投宽指数基金，例如沪深300。对普通投资者来说，投基金才是对确定性最大的追求。而买个股基本上会将自己置于非常大的风险之下。所以奉行弱者体系的多数人，就不该买个股。买个股的人多数认为自己是很强的，至少是弱者中的强者。进而，既然选择了买个股这条布满荆棘的强者之路，又如何追求确定性呢？正常来说我们要做好合理的仓位控制。在个股选择方面，要选择成长股，而不是不增长、高股息的价值股。为什么要选择成长股？这是因为成长股往往意味着企业目前发展势头不错，未来也可能发展不错，至少目前还没有看到明显的发展瓶颈。而不成长的价值股则常常表示这个企业已经遇到了问题，前景充满不确定性，市场估值给的很低。只有这种情况下，才有可能有高股息率，这就是我经常说的，你看重的是股息，但是把自己置于巨大的本金安全风险之下。对一个目前基本面不那么好的股，他的未来不外乎有三种可能。基本面转好，维持不动，变差。如果这个公司基本面好转，实现股价、业绩戴维斯双击，那么恭喜你，可以赚到大钱。但是如果不是因为运气因素，而是基于自身能力做出的选择，那么这对于个人能力要求非常高，属于顶级选手的能力。这个我们不探讨。而正常来说，一个基本面不好的公司，维持现状及变差的概率更大，这是企业及行业发展规律决定的。那么也就意味着，买入这种公司的确定性是不够的。那么如何看待投资成长股的确定性呢？在不考虑估值的情况下，成长股肯定有着更为确定的基本面，否则他也很难成为成长股。投资者之所以认为成长股投资有着巨大的不确定性，一方面是对这个公司的未来成长性把握不住，其次因为其当前估值很高。所以他们不选择成长股的逻辑也就很简单。一个看不清未来成长性的公司，目前估值又很高，这就有巨大的戴维斯双杀危险。其实对这类投资者，他既没有选择成长股的能力，也没有选择价值股的能力。他就不应该投资个股。事情又回到了我们一开始说的，一些应该投资基金的人由于缺乏对于自己的认知，误入个股投资场所而已。那么于真正的成长股投资者又该如何选择成长股呢？首先我们要承认，真正在我们能力范围内的成长股是很少的。不是打开F10，看着一个企业过往几年在成长就可以买的。这个股票必须在自己的能力范围内才行。其次，即使我们小心谨慎、认真选择，但也可能会看错。所以一定要分散持仓，买的便宜。成长股的投资机会不是什么时候都有的，一定要有足够的耐心。那些眼红某些股票大幅上涨，然后追高买入的人不是真正的投资者或者说不是低风险投资者。点评：1、90%以上的普通人最安全且长期收益最高的投资手段就是买指数基金；2、长期看低估值价值股的基本面恶化风险大，不是确定性投资选择；3、选择成长股本身对能力要求较高，需要能穿透基本面看出长期成长性，同时需要足够的耐心，买的够便宜。作者：二马由之链接：https://xueqiu.com/3081204011/182701699来源：雪球著作权归作者所有。商业转载请联系作者获得授权，非商业转载请注明出处。风险提示：本文所提到的观点仅代表个人的意见，所涉及标的不作推荐，据此买卖，风险自负。

I'm Matt Carlins and this is JUST Pro Wrestling News for Thursday, January 7, 2021. This update is sponsored by IndyWrestling.us. Results from NXT, MLW and New Japan's New Year Dash shows are straight ahead in this update but first.. (STINGER: AEW) Let's unpack the end of last night's AEW Dynamite..where the Kenny Omega/Impact Wrestling saga turned into a full fledged North American Bullet Club reunion. Omega beat Rey Fenix to retain his AEW title. He then revealed Eddie Kingston, The Butcher and The Blade had attacked Penta El Zero M and Pac backstage. Omega vowed to end Fenix, but Jon Moxley came to the rescue, armed with a barbed wire baseball bat. Mox got a few shots in on Omega before Karl Anderson and Doc Gallows - the Impact Wrestling Tag Team Champions - showed up to save Kenny. Their attack on Moxley eventually drew some of the wrestlers at ringside to get involved, but they were little help. Finally, the Young Bucks came out and ended up helping Omega. The final shot was the Bucks reluctantly joining Omega, Anderson and Gallows in a “Too Sweet”. The Bucks opened the show teaming with SCU to beat The Hydrid2 & The Acclaimed. After the match, Christopher Daniels made it clear that SCU is aiming for the Bucks' tag titles. Also last night, Cody Rhodes had Snoop Dogg in his corner as he beat Matt Sydal. Serpentico and Luther tried to jump Rhodes and Sydal after the match but were turned away and Snoop dropped a top rope splash on Serpentico. Hikaru Shida beat Abadon to hold onto the AEW women's title. And Wardlow hit the F10 and beat Jake Hager. The two exchanged a mutual respect fist bump after the match. Chuck Taylor said Trent will be out of action for 4-5 months with a torn pec. Taylor will face Miro next week, and if Chuck loses he has to be Miro's “young boy”. Also added to next week's show: Serena Deeb defending the NWA Women's Title against Tay Conti...and Eddie Kingston vs. Pac. (STINGER: WWE) Finn Balor is still the NXT Champion. He beat Kyle O'Reilly via submission on last night's NXT. Raquel Gonzalez beat Rhea Ripley in their Last Woman Standing match after Gonzalez choke slammed Ripley through the entrance stage. Karrion Kross beat Damien Priest. And Santos Escaor retained his cruiserweight title against Gran Metalik. The FIGHT PIT match between Tommasso Ciampa and Timothy Thatcher was pulled from last night's show due to an injury for Thatcher. Also, the next NXT TakeOver special on the WWE Network will be on Valentine's Day - Sunday, February 14th. Dusty Rhodes Tag Team Classic begins next week with a pair of first round matches: Adam Cole and Roderick Strong vs. Breezango...and the Grizzled Young Veterans vs. Ever-Rise. NXT also announced the first-ever WOMEN'S Dusty Rhodes Tag Team Classic is coming soon. The only title change on Wednesday was the MLW World Middleweight Championship. Lio Rush dethroned Myron Reed. MLW's Court Bauer says the league is in talks with at least two “major” networks about expanding its programming. (Bauer MLW TV Talks) Bauer speaking with Fightful's Sean Ross Sapp. (STINGER: New Japan) New title challengers coming into focus at New Japan's New Year Dash show Wednesday. The main event mult-man tag match setting up NEVER champ Shingo Takagi vs Hiroshi Tanahashi...and HIromu Takahashi defending his junior heavyweight title against SHO. On the undercard, El Phantasmo pinned Yoshinobu Kanemaru after a suspiciously powerful superkick. That puts ELP and Taiji Ishimori in line for a shot at the jr tag titles held by Kanemaru and El Desperado. The Empire laid waste to Hiroyoshi Tenzan to the point that he was stretchered out of the arena. Kazuchika Okada now has his sights set on EVIL. As for Jay White...He was pinned by Tomohiro Ishii - as CHAOS beat Bullet Club in a 10-man tag. White was carried to the back, but there was no further follow-up to his post-Wrestle Kingdom comments that he's “done” in New Japan. Ring Of Honor announcing Amy Rose has re-signed with the company. That's JUST Pro Wrestling News for Thursday, January 7. Our next update comes your way tomorrow morning, so be sure to subscribe to this feed.

If you want to find out more about overseas mapping for Garmin users please go to gpstraining.co.uk – click on – GPS Store and the left hand side under mapping you will see Open Street Maps – Garmin GPS 3 – Shift of magnetic North What is magnetic North? Difference between magnetic north (where the compass points) and grid north (the vertical blue grid lines shown on OS maps).The difference between magnetic north and grid north is often referred to as grid magnetic angle and it not only varies from place to place, but changes with time too, and needs to be taken into account when navigating with a map and compass.Back in 2014 there was a significant event in the changing direction of magnetic north relative to grid north on OS maps. For the first time in Great Britain since the 1660s, magnetic north moved from being to the west of grid north to the east. The change started in the South West corner of Britain, currently affects the areas to the west of the line on our map, and will slowly progress across the whole country over the next 12 to 13 years. Shift of magnetic field – The latest World Magnetic Model was designed to last until 2020, but magnetic north's rapid and unexpected surge toward Siberia was so great, that researchers had to amend the model early.

Papers we love: ARC by Bryan Cantrill, SSD caching adventures with ZFS, OpenBSD full disk encryption setup, and a Perl5 Slack Syslog BSD daemon. This episode was brought to you by Headlines Papers We Love: ARC: A Self-Tuning, Low Overhead Replacement Cache (https://www.youtube.com/watch?v=F8sZRBdmqc0&feature=youtu.be) Ever wondered how the ZFS ARC (Adaptive Replacement Cache) works? How about if Bryan Cantrill presented the original paper on its design? Today is that day. Slides (https://www.slideshare.net/bcantrill/papers-we-love-arc-after-dark) It starts by looking back at a fundamental paper from the 40s where the architecture of general-purpose computers are first laid out The main is the description of memory hierarchies, where you have a small amount of very fast memory, then the next level is slower but larger, and on and on. As we look at the various L1, L2, and L3 caches on a CPU, then RAM, then flash, then spinning disks, this still holds true today. The paper then does a survey of the existing caching policies and tries to explain the issues with each. This includes ‘MIN', which is the theoretically optimal policy, which requires future knowledge, but is useful for setting the upper bound, what is the best we could possibly do. The paper ends up showing that the ARC can end up being better than manually trying to pick the best number for the workload, because it adapts as the workload changes At about 1:25 into the video, Bryan start talking about the practical implementation of the ARC in ZFS, and some challenges they have run into recently at Joyent. A great discussion about some of the problems when ZFS needs to shrink the ARC. Not all of it applies 1:1 to FreeBSD because the kernel and the kmem implementation are different in a number of ways There were some interesting questions asked at the end as well *** How do I use man pages to learn how to use commands? (https://unix.stackexchange.com/a/193837) nwildner on StackExchange has a very thorough answer to the question how to interpret man pages to understand complicated commands (xargs in this case, but not specifically). Have in mind what you want to do. When doing your research about xargs you did it for a purpose, right? You had a specific need that was reading standard output and executing commands based on that output. But, when I don't know which command I want? Use man -k or apropos (they are equivalent). If I don't know how to find a file: man -k file | grep search. Read the descriptions and find one that will better fit your needs. Apropos works with regular expressions by default, (man apropos, read the description and find out what -r does), and on this example I'm looking for every manpage where the description starts with "report". Always read the DESCRIPTION before starting Take a time and read the description. By just reading the description of the xargs command we will learn that: xargs reads from STDIN and executes the command needed. This also means that you will need to have some knowledge of how standard input works, and how to manipulate it through pipes to chain commands The default behavior is to act like /bin/echo. This gives you a little tip that if you need to chain more than one xargs, you don't need to use echo to print. We have also learned that unix filenames can contain blank and newlines, that this could be a problem and the argument -0 is a way to prevent things explode by using null character separators. The description warns you that the command being used as input needs to support this feature too, and that GNU find support it. Great. We use a lot of find with xargs. xargs will stop if exit status 255 is reached. Some descriptions are very short and that is generally because the software works on a very simple way. Don't even think of skipping this part of the manpage ;) Other things to pay attention... You know that you can search for files using find. There is a ton of options and if you only look at the SYNOPSIS, you will get overwhelmed by those. It's just the tip of the iceberg. Excluding NAME, SYNOPSIS, and DESCRIPTION, you will have the following sections: When this method will not work so well... + Tips that apply to all commands Some options, mnemonics and "syntax style" travel through all commands making you buy some time by not having to open the manpage at all. Those are learned by practice and the most common are: Generally, -v means verbose. -vvv is a variation "very very verbose" on some software. Following the POSIX standard, generally one dash arguments can be stacked. Example: tar -xzvf, cp -Rv. Generally -R and/or -r means recursive. Almost all commands have a brief help with the --help option. --version shows the version of a software. -p, on copy or move utilities means "preserve permissions". -y means YES, or "proceed without confirmation" in most cases. Default values of commands. At the pager chunk of this answer, we saw that less -is is the pager of man. The default behavior of commands are not always shown at a separated section on manpages, or at the section that is most top placed. You will have to read the options to find out defaults, or if you are lucky, typing /pager will lead you to that info. This also requires you to know the concept of the pager(software that scrolls the manpage), and this is a thing you will only acquire after reading lots of manpages. And what about the SYNOPSIS syntax? After getting all the information needed to execute the command, you can combine options, option-arguments and operands inline to make your job done. Overview of concepts: Options are the switches that dictates a command behavior. "Do this" "don't do this" or "act this way". Often called switches. Check out the full answer and see if it helps you better grasp the meaning of a man page and thus the command. *** My adventure into SSD caching with ZFS (Home NAS) (https://robertputt.co.uk/my-adventure-into-ssd-caching-with-zfs-home-nas.html) Robert Putt as written about his adventure using SSDs for caching with ZFS on his home NAS. Recently I decided to throw away my old defunct 2009 MacBook Pro which was rotting in my cupboard and I decided to retrieve the only useful part before doing so, the 80GB Intel SSD I had installed a few years earlier. Initially I thought about simply adding it to my desktop as a bit of extra space but in 2017 80GB really wasn't worth it and then I had a brainwave… Lets see if we can squeeze some additional performance out of my HP Microserver Gen8 NAS running ZFS by installing it as a cache disk. I installed the SSD to the cdrom tray of the Microserver using a floppy disk power to SATA power converter and a SATA cable, unfortunately it seems the CD ROM SATA port on the motherboard is only a 3gbps port although this didn't matter so much as it was an older 3gbps SSD anyway. Next I booted up the machine and to my suprise the disk was not found in my FreeBSD install, then I realised that the SATA port for the CD drive is actually provided by the RAID controller, so I rebooted into intelligent provisioning and added an additional RAID0 array with just the 1 disk to act as my cache, in fact all of the disks in this machine are individual RAID0 arrays so it looks like just a bunch of disks (JBOD) as ZFS offers additional functionality over normal RAID (mainly scrubbing, deduplication and compression). Configuration Lets have a look at the zpool before adding the cache drive to make sure there are no errors or uglyness: Now lets prep the drive for use in the zpool using gpart. I want to split the SSD into two seperate partitions, one for L2ARC (read caching) and one for ZIL (write caching). I have decided to split the disk into 20GB for ZIL and 50GB for L2ARC. Be warned using 1 SSD like this is considered unsafe because it is a single point of failure in terms of delayed writes (a redundant configuration with 2 SSDs would be more appropriate) and the heavy write cycles on the SSD from the ZIL is likely to kill it over time. Now it's time to see if adding the cache has made much of a difference. I suspect not as my Home NAS sucks, it is a HP Microserver Gen8 with the crappy Celeron CPU and only 4GB RAM, anyway, lets test it and find out. First off lets throw fio at the mount point for this zpool and see what happens both with the ZIL and L2ARC enabled and disabled. Observations Ok, so the initial result is a little dissapointing, but hardly unexpected, my NAS sucks and there are lots of bottle necks, CPU, memory and the fact only 2 of the SATA ports are 6gbps. There is no real difference performance wise in comparison between the results, the IOPS, bandwidth and latency appear very similar. However lets bare in mind fio is a pretty hardcore disk benchmark utility, how about some real world use cases? Next I decided to test a few typical file transactions that this NAS is used for, Samba shares to my workstation. For the first test I wanted to test reading a 3GB file over the network with both the cache enabled and disabled, I would run this multiple times to ensure the data is hot in the L2ARC and to ensure the test is somewhat repeatable, the network itself is an uncongested 1gbit link and I am copying onto the secondary SSD in my workstation. The dataset for these tests has compression and deduplication disabled. Samba Read Test Not bad once the data becomes hot in the L2ARC cache reads appear to gain a decent advantage compared to reading from the disk directly. How does it perform when writing the same file back accross the network using the ZIL vs no ZIL. Samba Write Test Another good result in the real world test, this certainately helps the write transfer speed however I do wonder what would happen if you filled the ZIL transferring a very large file, however this is unlikely with my use case as I typically only deal with a couple of files of several hundred megabytes at any given time so a 20GB ZIL should suit me reasonably well. Is ZIL and L2ARC worth it? I would imagine with a big beefy ZFS server running in a company somewhere with a large disk pool and lots of users with multiple enterprise level SSD ZIL and L2ARC would be well worth the investment, however at home I am not so sure. Yes I did see an increase in read speeds with cached data and a general increase in write speeds however it is use case dependant. In my use case I rarely access the same file frequently, my NAS primarily serves as a backup and for archived data, and although the write speeds are cool I am not sure its a deal breaker. If I built a new home NAS today I'd probably concentrate the budget on a better CPU, more RAM (for ARC cache) and more disks. However if I had a use case where I frequently accessed the same files and needed to do so in a faster fashion then yes, I'd probably invest in an SSD for caching. I think if you have a spare SSD lying around and you want something fun todo with it, sure chuck it in your ZFS based NAS as a cache mechanism. If you were planning on buying an SSD for caching then I'd really consider your needs and decide if the money can be spent on alternative stuff which would improve your experience with your NAS. I know my NAS would benefit more from an extra stick of RAM and a more powerful CPU, but as a quick evening project with some parts I had hanging around adding some SSD cache was worth a go. More Viewer Interview Questions for Allan News Roundup Setup OpenBSD 6.2 with Full Disk Encryption (https://blog.cagedmonster.net/setup-openbsd-with-full-disk-encryption/) Here is a quick way to setup (in 7 steps) OpenBSD 6.2 with the encryption of the filesystem. First step: Boot and start the installation: (I)nstall: I Keyboard Layout: ENTER (I'm french so in my case I took the FR layout) Leave the installer with: ! Second step: Prepare your disk for encryption. Using a SSD, my disk is named : sd0, the name may vary, for example : wd0. Initiating the disk: Configure your volume: Now we'll use bioctl to encrypt the partition we created, in this case : sd0a (disk sd0 + partition « a »). Enter your passphrase. Third step: Let's resume the OpenBSD's installer. We follow the install procedure Fourth step: Partitioning of the encrypted volume. We select our new volume, in this case: sd1 The whole disk will be used: W(hole) Let's create our partitions: NB: You are more than welcome to create multiple partitions for your system. Fifth step: System installation It's time to choose how we'll install our system (network install by http in my case) Sixth step: Finalize the installation. Last step: Reboot and start your system. Put your passphrase. Welcome to OpenBSD 6.2 with a full encrypted file system. Optional: Disable the swap encryption. The swap is actually part of the encrypted filesystem, we don't need OpenBSD to encrypt it. Sysctl is giving us this possibility. Step-by-Step FreeBSD installation with ZFS and Full Disk Encryption (https://blog.cagedmonster.net/step-by-step-freebsd-installation-with-full-disk-encryption/) 1. What do I need? For this tutorial, the installation has been made on a Intel Core i7 - AMD64 architecture. On a USB key, you would probably use this link : ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/amd64/ISO-IMAGES/11.1/FreeBSD-11.1-RELEASE-amd64-mini-memstick.img If you can't do a network installation, you'd better use this image : ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/amd64/ISO-IMAGES/11.1/FreeBSD-11.1-RELEASE-amd64-memstick.img You can write the image file on your USB device (replace XXXX with the name of your device) using dd : # dd if=FreeBSD-11.1-RELEASE-amd64-mini-memstick.img of=/dev/XXXX bs=1m 2.

And this post should also be a reference for other*NIX OSs. The ELF (https://en.wikipedia.org/wiki/Executable_and_Linkable_Format) file is divided into 4 categories: relocatable, executable, shared, and core. Only the executable and shared object files may have dynamic object dependencies, so the ldd only check these 2 kinds of ELF file: (1) Executable. ldd leverages the LD_TRACE_LOADED_OBJECTS environment variable in fact, and the code is as following: if (setenv("LD_TRACE_LOADED_OBJECTS", "true", 1) < 0) err(1, "setenv(LD_TRACE_LOADED_OBJECTS)"); When LDTRACELOADED_OBJECTS is set to 1 or true, running executable file will show shared objects needed instead of running it, so you even not needldd to check executable file. See the following outputs: $ /usr/bin/ldd usage: ldd program ... $ LD_TRACE_LOADED_OBJECTS=1 /usr/bin/ldd Start End Type Open Ref GrpRef Name 00000b6ac6e00000 00000b6ac7003000 exe 1 0 0 /usr/bin/ldd 00000b6dbc96c000 00000b6dbcc38000 rlib 0 1 0 /usr/lib/libc.so.89.3 00000b6d6ad00000 00000b6d6ad00000 rtld 0 1 0 /usr/libexec/ld.so (2) Shared object. The code to print dependencies of shared object is as following: if (ehdr.e_type == ET_DYN && !interp) { if (realpath(name, buf) == NULL) { printf("realpath(%s): %s", name, strerror(errno)); fflush(stdout); _exit(1); } dlhandle = dlopen(buf, RTLD_TRACE); if (dlhandle == NULL) { printf("%sn", dlerror()); fflush(stdout); _exit(1); } _exit(0); } Why the condition of checking a ELF file is shared object or not is like this: if (ehdr.e_type == ET_DYN && !interp) { ...... } That's because the file type of position-independent executable (PIE) is the same as shared object, but normally PIE contains a interpreter program header since it needs dynamic linker to load it while shared object lacks (refer this article). So the above condition will filter PIE file. The dlopen(buf, RTLD_TRACE) is used to print dynamic object information. And the actual code is like this: if (_dl_traceld) { _dl_show_objects(); _dl_unload_shlib(object); _dl_exit(0); } In fact, you can also implement a simple application which outputs dynamic object information for shared object yourself: # include int main(int argc, char **argv) { dlopen(argv[1], RTLD_TRACE); return 0; } Compile and use it to analyze /usr/lib/libssl.so.43.2: $ cc lddshared.c $ ./a.out /usr/lib/libssl.so.43.2 Start End Type Open Ref GrpRef Name 000010e2df1c5000 000010e2df41a000 dlib 1 0 0 /usr/lib/libssl.so.43.2 000010e311e3f000 000010e312209000 rlib 0 1 0 /usr/lib/libcrypto.so.41.1 The same as using ldd directly: $ ldd /usr/lib/libssl.so.43.2 /usr/lib/libssl.so.43.2: Start End Type Open Ref GrpRef Name 00001d9ffef08000 00001d9fff15d000 dlib 1 0 0 /usr/lib/libssl.so.43.2 00001d9ff1431000 00001d9ff17fb000 rlib 0 1 0 /usr/lib/libcrypto.so.41.1 Through the studying of ldd source code, I also get many by-products: such as knowledge of ELF file, linking and loading, etc. So diving into code is a really good method to learn *NIX deeper! Perl5 Slack Syslog BSD daemon (https://clinetworking.wordpress.com/2017/10/13/perl5-slack-syslog-bsd-daemon/) So I have been working on my little Perl daemon for a week now. It is a simple syslog daemon that listens on port 514 for incoming messages. It listens on a port so it can process log messages from my consumer Linux router as well as the messages from my server. Messages that are above alert are sent, as are messages that match the regex of SSH or DHCP (I want to keep track of new connections to my wifi). The rest of the messages are not sent to slack but appended to a log file. This is very handy as I can get access to info like failed ssh logins, disk failures, and new devices connecting to the network all on my Android phone when I am not home. Screenshot (https://clinetworking.files.wordpress.com/2017/10/screenshot_2017-10-13-23-00-26.png) The situation arose today that the internet went down and I thought to myself what would happen to all my important syslog messages when they couldn't be sent? Before the script only ran an eval block on the botsend() function. The error was returned, handled, but nothing was done and the unsent message was discarded. So I added a function that appended unsent messengers to an array that are later sent when the server is not busy sending messages to slack. Slack has a limit of one message per second. The new addition works well and means that if the internet fails my server will store these messages in memory and resend them at a rate of one message per second when the internet connectivity returns. It currently sends the newest ones first but I am not sure if this is a bug or a feature at this point! It currently works with my Linux based WiFi router and my FreeBSD server. It is easy to scale as all you need to do is send messages to syslog to get them sent to slack. You could sent CPU temp, logged in users etc. There is a github page: https://github.com/wilyarti/slackbot Lscpu for OpenBSD/FreeBSD (http://nanxiao.me/en/lscpu-for-openbsdfreebsd/) Github Link (https://github.com/NanXiao/lscpu) There is a neat command, lscpu, which is very handy to display CPU information on GNU/Linux OS: $ lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 32 On-line CPU(s) list: 0-31 Thread(s) per core: 2 Core(s) per socket: 8 Socket(s): 2 But unfortunately, the BSD OSs lack this command, maybe one reason is lscpu relies heavily on /proc file system which BSD don't provide, :-). TakeOpenBSD as an example, if I want to know CPU information, dmesg should be one choice: $ dmesg | grep -i cpu cpu0 at mainbus0: apid 0 (boot processor) cpu0: Intel(R) Core(TM)2 Duo CPU P8700 @ 2.53GHz, 2527.35 MHz cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM, PBE,SSE3,DTES64,MWAIT,DS-CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,SSE4.1,XSAVE,NXE,LONG,LAHF,PERF,SENSOR cpu0: 3MB 64b/line 8-way L2 cache cpu0: apic clock running at 266MHz cpu0: mwait min=64, max=64, C-substates=0.2.2.2.2.1.3, IBE But the output makes me feeling messy, not very clear. As for dmidecode, it used to be another option, but now can't work out-of-box because it will access /dev/mem which for security reason, OpenBSD doesn't allow by default (You can refer this discussion): $ ./dmidecode $ dmidecode 3.1 Scanning /dev/mem for entry point. /dev/mem: Operation not permitted Based on above situation, I want a specified command for showing CPU information for my BSD box. So in the past 2 weeks, I developed a lscpu program for OpenBSD/FreeBSD, or more accurately, OpenBSD/FreeBSD on x86 architecture since I only have some Intel processors at hand. The application getsCPU metrics from 2 sources: (1) sysctl functions. The BSD OSs provide sysctl interface which I can use to get general CPU particulars, such as how many CPUs the system contains, the byte-order of CPU, etc. (2) CPUID instruction. For x86 architecture, CPUID instruction can obtain very detail information of CPU. This coding work is a little tedious and error-prone, not only because I need to reference both Intel and AMD specifications since these 2 vendors have minor distinctions, but also I need to parse the bits of register values. The code is here (https://github.com/NanXiao/lscpu), and if you run OpenBSD/FreeBSD on x86 processors, please try it. It will be better you can give some feedback or report the issues, and I appreciate it very much. In the future if I have other CPUs resource, such as ARM or SPARC64, maybe I will enrich this small program. *** Beastie Bits OpenBSD Porting Workshop - Brian Callahan will be running an OpenBSD porting workshop in NYC for NYC*BUG on December 6, 2017.

Alex Gore from http://www.f9productions.com (F9 Productions) discussed his work with Daniel Libeskind, his firm in Longmont, Colorado, his podcast, http://Insidethefirmpodcast.com (Inside The Firm), sharing the behind-the-scenes with his partner, Lance Cayko, and his book http://amzn.to/2gRcHMY (The Creativity Code). This week on EntreArchitect Podcast, EntreArchitect Live with Alex Gore of http://www.f9productions.com (F9 Productions). Background Alex Gore grew up drawing wars of ants verses bees, playing backyard baseball, and being obsessed with Frank Lloyd Wright. After high school, he joined the national guard as a heavy equipment operator. There, he attended North Dakota State University and received a masters in architecture and construction management. He then worked under the world-famous architect Daniel Libeskind, teamed up with his best friend from college Lance Cayko to start F9 Productions. He’s the cohost of http://www.insidethefirmpodcast.com (Inside the Firm Podcast) and the author of http://amzn.to/2gRcHMY (The Creativity Code). How did you get to work for Daniel Libeskind? Going into Denver, Alex lined up several different interviews when he had a trip planned to be in town. He was back and forth with Libeskind, and was offered an internship first. Though he turned that down, he eventually was offered a full-time position. Did you carry any thoughts over from Libeskind to F9 Productions? Daniel Libeskind always did crazy fun projects, so Alex and Lance have tried to keep doing one fun project a year. They http://www.atlastinyhouse.com (built a tiny house) that was sustainable and cooler looking than traditional tiny houses. The goal was to make a commitment to do something cool every year. What are your thoughts on interning for a star firm? All of us interns worked a ton and were paid an hourly rate. At F9 Productions, interns are paid. When you’re sacrificing your time and energy in a studio culture environment, you have a lot to learn by doing that if that’s what you want to do. For F9 Productions, interns are just colleagues and designers who they work side by side with. How did F9 Productions start? When Alex got laid off by Libeskind, he called Lance and they made some plans. Eventually, Lance got laid off as well and Alex decided to move to Colorado and figure out how to work together. They worked as a tw0-man shop for a few years until they had consistent business in 2013-2014. Now, they have about ten people and even that feels stretched at times. The structure is a two-headed beast. They each have people who mainly work for one of them or the other, and in times of big projects they can pull from the other’s side. Depending on the project, they tend to hand off projects that are a better fit for the other person’s skills. Where did the name for F9 Productions come from? In college, Alex and Lance didn’t know if they really liked each other. When they finally realized each other had some useful skills, they worked closely together. They were on their computers all the time, and F9 was the key to render. They would tease their classmates who wanted to go home at the end of the day by saying, “Go ahead! Just hit F9 and the computer will do the work while you get some rest.” It’s progressed that their different companies now are set up following suit: F10, F11, F12 and F14. Are you going to sell your development units individually? We couldn’t separate the parcels, so they’ll be condos with an HOA. We’ll sell 6 on one side as units, and there’s still talk of renting the two on the other side. Do you think every architect should do development? Alex thinks the majority of...

Today on the show, we've got a look at running OpenBSD on a APU, some BSD in your Android, managing your own FreeBSD cloud service with ansible and much more. Keep it turned on your place to B...SD! This episode was brought to you by Headlines OpenBSD on PC Engines APU2 (https://github.com/elad/openbsd-apu2) A detailed walkthrough of building an OpenBSD firewall on a PC Engines APU2 It starts with a breakdown of the parts that were purchases, totally around $200 Then the reader is walked through configuring the serial console, flashing the ROM, and updating the BIOS The next step is actually creating a custom OpenBSD install image, and pre-configuring its serial console. Starting with OpenBSD 6.0, this step is done automatically by the installer Installation: Power off the APU2 Insert the bootable OpenBSD installer USB flash drive to one of the USB slots on the APU2 Power on the APU2, press F10 to get to the boot menu, and choose to boot from USB (usually option number 1) At the boot> prompt, remember the serial console settings (see above) Also at the boot> prompt, press Enter to start the installer Follow the installation instructions The driver used for wireless networking is athn(4). It might not work properly out of the box. Once OpenBSD is installed, run fw_update with no arguments. It will figure out which firmware updates are required and will download and install them. When it finishes, reboot. Where the rubber meets the road… (part one) (https://functionallyparanoid.com/2016/11/29/where-the-rubber-meets-the-road-part-one/) A user describes their adventures installing OpenBSD and Arch Linux on a new Lenovo X1 Carbon (4th gen, skylake) They also detail why they moved away from their beloved Macbook, which while long, does describe a journey away from Apple that we've heard elsewhere. The journey begins with getting a new Windows laptop, shrinking the partition and creating space for a triple-boot install, of Windows / Arch / OpenBSD Brian then details how he setup the partitioning and performed the initial Arch installation, getting it tuned to his specifications. Next up was OpenBSD though, and that went sideways initially due to a new NVMe drive that wasn't fully supported (yet) The article is split into two parts (we will bring you the next installment at a future date), but he leaves us with the plan of attack to build a custom OpenBSD kernel with corrected PCI device identifiers. We wish Brian luck, and look forward to the “rest of the story” soon. *** Howto setup a FreeBSD jail server using iocage and ansible. (https://github.com/JoergFiedler/freebsd-ansible-demo) Setting up a FreeBSD jail server can be a daunting task. However when a guide comes along which shows you how to do that, including not exposing a single (non-jailed) port to the outside world, you know we had a take a closer look. This guide comes to us from GitHub, courtesy of Joerg Fielder. The project goals seem notable: Ansible playbook that creates a FreeBSD server which hosts multiple jails. Travis is used to run/test the playbook. No service on the host is exposed externally. All external connections terminate within a jail. Roles can be reused using Ansible Galaxy. Combine any of those roles to create FreeBSD server, which perfectly suits you. To get started, you'll need a machine with Ansible, Vagrant and VirtualBox, and your credentials to AWS if you want it to automatically create / destroy EC2 instances. There's already an impressive list of Anisible roles created for you to start with: freebsd-build-server - Creates a FreeBSD poudriere build server freebsd-jail-host - FreeBSD Jail host freebsd-jailed - Provides a jail freebsd-jailed-nginx - Provides a jailed nginx server freebsd-jailed-php-fpm - Creates a php-fpm pool and a ZFS dataset which is used as web root by php-fpm freebsd-jailed-sftp - Installs a SFTP server freebsd-jailed-sshd - Provides a jailed sshd server. freebsd-jailed-syslogd - Provides a jailed syslogd freebsd-jailed-btsync - Provides a jailed btsync instance server freebsd-jailed-joomla - Installs Joomla freebsd-jailed-mariadb - Provides a jailed MariaDB server freebsd-jailed-wordpress - Provides a jailed Wordpress server. Since the machines have to be customized before starting, he mentions that cloud-init is used to do the following: activate pf firewall add a pass all keep state rule to pf to keep track of connection states, which in turn allows you to reload the pf service without losing the connection install the following packages: sudo bash python27 allow passwordless sudo for user ec2-user “ From there it is pretty straight-forward, just a couple commands to spin up the VM's either locally on your VirtualBox host, or in the cloud with AWS. Internally the VM's are auto-configured with iocage to create jails, where all your actual services run. A neat project, check it out today if you want a shake-n-bake type cloud + jail solution. Colin Percival's bsdiff helps reduce Android apk bandwidth usage by 6 petabytes per day (http://android-developers.blogspot.ca/2016/12/saving-data-reducing-the-size-of-app-updates-by-65-percent.html) A post on the official Android-Developers blog, talks about how they used bsdiff (and bspatch) to reduce the size of Android application updates by 65% bsdiff was developed by FreeBSD's Colin Percival Earlier this year, we announced that we started using the bsdiff algorithm (by Colin Percival). Using bsdiff, we were able to reduce the size of app updates on average by 47% compared to the full APK size. This post is actually about the second generation of the code. Today, we're excited to share a new approach that goes further — File-by-File patching. App Updates using File-by-File patching are, on average, 65% smaller than the full app, and in some cases more than 90% smaller. Android apps are packaged as APKs, which are ZIP files with special conventions. Most of the content within the ZIP files (and APKs) is compressed using a technology called Deflate. Deflate is really good at compressing data but it has a drawback: it makes identifying changes in the original (uncompressed) content really hard. Even a tiny change to the original content (like changing one word in a book) can make the compressed output of deflate look completely different. Describing the differences between the original content is easy, but describing the differences between the compressed content is so hard that it leads to inefficient patches. So in the second generation of the code, they use bsdiff on each individual file, then package that, rather than diffing the original and new archives bsdiff is used in a great many other places, including shrinking the updates for the Firefox and Chrome browsers You can find out more about bsdiff here: http://www.daemonology.net/bsdiff/ A far more sophisticated algorithm, which typically provides roughly 20% smaller patches, is described in my doctoral thesis (http://www.daemonology.net/papers/thesis.pdf). Considering the gains, it is interesting that no one has implemented Colin's more sophisticated algorithm Colin had an interesting observation (https://twitter.com/cperciva/status/806426180379230208) last night: “I just realized that bandwidth savings due to bsdiff are now roughly equal to what the total internet traffic was when I wrote it in 2003.” *** News Roundup Distrowatch does an in-depth review of NAS4Free (https://distrowatch.com/weekly.php?issue=20161114#nas4free) Jesse Smith over at DistroWatch has done a pretty in-depth review of Nas4Free. The review starts with mentioning that NAS4Free works on 3 platforms, ARM/i386/AMD64 and for the purposes of this review he would be using AMD64 builds. After going through the initial install (doing typical disk management operations, such as GPT/MBR, etc) he was ready to begin using the product. One concern originally observed was that the initial boot seemed rather slow. Investigation revealed this was due to it loading the entire OS image into memory, and the first (long) disk read did take some time, but once loaded was super responsive. The next steps involved doing the initial configuration, which meant creating a new ZFS storage pool. After this process was done, he did find one puzzling UI option called “VM” which indicated it can be linked to VirtualBox in some way, but the Docs didn't reveal its secrets of usage. Additionally covered were some of the various “Access” methods, including traditional UNIX permissions, AD and LDAP, and then various Sharing services which are typical to a NAS, Such as NFS / Samba and others. One neat feature was the built-in file-browser via the web-interface, which allows you another method of getting at your data when sometimes NFS / Samba or WebDav aren't enough. Jesse gives us a nice round-up conclusion as well Most of the NAS operating systems I have used in the past were built around useful features. Some focused on making storage easy to set up and manage, others focused on services, such as making files available over multiple protocols or managing torrents. Some strive to be very easy to set up. NAS4Free does pretty well in each of the above categories. It may not be the easiest platform to set up, but it's probably a close second. It may not have the prettiest interface for managing settings, but it is quite easy to navigate. NAS4Free may not have the most add-on services and access protocols, but I suspect there are more than enough of both for most people. Where NAS4Free does better than most other solutions I have looked at is security. I don't think the project's website or documentation particularly focuses on security as a feature, but there are plenty of little security features that I liked. NAS4Free makes it very easy to lock the text console, which is good because we do not all keep our NAS boxes behind locked doors. The system is fairly easy to upgrade and appears to publish regular security updates in the form of new firmware. NAS4Free makes it fairly easy to set up user accounts, handle permissions and manage home directories. It's also pretty straight forward to switch from HTTP to HTTPS and to block people not on the local network from accessing the NAS's web interface. All in all, I like NAS4Free. It's a good, general purpose NAS operating system. While I did not feel the project did anything really amazing in any one category, nor did I run into any serious issues. The NAS ran as expected, was fairly straight forward to set up and easy to manage. This strikes me as an especially good platform for home or small business users who want an easy set up, some basic security and a solid collection of features. Browsix: Unix in the browser tab (https://browsix.org/) Browsix is a research project from the PLASMA lab at the University of Massachusetts, Amherst. The goal: Run C, C++, Go and Node.js programs as processes in browsers, including LaTeX, GNU Make, Go HTTP servers, and POSIX shell scripts. “Processes are built on top of Web Workers, letting applications run in parallel and spawn subprocesses. System calls include fork, spawn, exec, and wait.” Pipes are supported with pipe(2) enabling developers to compose processes into pipelines. Sockets include support for TCP socket servers and clients, making it possible to run applications like databases and HTTP servers together with their clients in the browser. Browsix comprises two core parts: A kernel written in TypeScript that makes core Unix features (including pipes, concurrent processes, signals, sockets, and a shared file system) available to web applications. Extended JavaScript runtimes for C, C++, Go, and Node.js that support running programs written in these languages as processes in the browser. This seems like an interesting project, although I am not sure how it would be used as more than a toy *** Book Review: PAM Mastery (https://www.cyberciti.biz/reviews/book-review-pam-mastery/) nixCraft does a book review of Michael W. Lucas' “Pam Mastery” Linux, FreeBSD, and Unix-like systems are multi-user and need some way of authenticating individual users. Back in the old days, this was done in different ways. You need to change each Unix application to use different authentication scheme. Before PAM, if you wanted to use an SQL database to authenticate users, you had to write specific support for that into each of your applications. Same for LDAP, etc. So Open Group lead to the development of PAM for the Unix-like system. Today Linux, FreeBSD, MacOS X and many other Unix-like systems are configured to use a centralized authentication mechanism called Pluggable Authentication Modules (PAM). The book “PAM Mastery” deals with the black magic of PAM. Of course, each OS chose to implement PAM a little bit differently The book starts with the basic concepts about PAM and authentication. You learn about Multi-Factor Authentication and why use PAM instead of changing each program to authenticate the user. The author went into great details about why PAM is useful for developers and sysadmin for several reasons. The examples cover CentOS Linux (RHEL and clones), Debian Linux, and FreeBSD Unix system. I like the way the author described PAM Configuration Files and Common Modules that covers everyday scenarios for the sysadmin. PAM configuration file format and PAM Module Interfaces are discussed in easy to understand language. Control flags in PAM can be very confusing for new sysadmins. Modules can be stacked in a particular order, and the control flags determine how important the success or failure of a particular module. There is also a chapter about using one-time passwords (Google Authenticator) for your application. The final chapter is all about enforcing good password policies for users and apps using PAM. The sysadmin would find this book useful as it covers a common authentication scheme that can be used with a wide variety of applications on Unix. You will master PAM topics and take control over authentication for your organization IT infrastructure. If you are Linux or Unix sysadmin, I would highly recommend this book. Once again Michael W Lucas nailed it. The only book you may need for PAM deployment. get “PAM Mastery” (https://www.michaelwlucas.com/tools/pam) *** Reflections on Trusting Trust - Ken Thompson, co-author of UNIX (http://www.win.tue.nl/~aeb/linux/hh/thompson/trust.html) Ken Thompson's "cc hack" - Presented in the journal, Communication of the ACM, Vol. 27, No. 8, August 1984, in a paper entitled "Reflections on Trusting Trust", Ken Thompson, co-author of UNIX, recounted a story of how he created a version of the C compiler that, when presented with the source code for the "login" program, would automatically compile in a backdoor to allow him entry to the system. This is only half the story, though. In order to hide this trojan horse, Ken also added to this version of "cc" the ability to recognize if it was recompiling itself to make sure that the newly compiled C compiler contained both the "login" backdoor, and the code to insert both trojans into a newly compiled C compiler. In this way, the source code for the C compiler would never show that these trojans existed. The article starts off by talking about a content to write a program that produces its own source code as output. Or rather, a C program, that writes a C program, that produces its own source code as output. The C compiler is written in C. What I am about to describe is one of many "chicken and egg" problems that arise when compilers are written in their own language. In this case, I will use a specific example from the C compiler. Suppose we wish to alter the C compiler to include the sequence "v" to represent the vertical tab character. The extension to Figure 2 is obvious and is presented in Figure 3. We then recompile the C compiler, but we get a diagnostic. Obviously, since the binary version of the compiler does not know about "v," the source is not legal C. We must "train" the compiler. After it "knows" what "v" means, then our new change will become legal C. We look up on an ASCII chart that a vertical tab is decimal 11. We alter our source to look like Figure 4. Now the old compiler accepts the new source. We install the resulting binary as the new official C compiler and now we can write the portable version the way we had it in Figure 3. The actual bug I planted in the compiler would match code in the UNIX "login" command. The replacement code would miscompile the login command so that it would accept either the intended encrypted password or a particular known password. Thus if this code were installed in binary and the binary were used to compile the login command, I could log into that system as any user. Such blatant code would not go undetected for long. Even the most casual perusal of the source of the C compiler would raise suspicions. Next “simply add a second Trojan horse to the one that already exists. The second pattern is aimed at the C compiler. The replacement code is a Stage I self-reproducing program that inserts both Trojan horses into the compiler. This requires a learning phase as in the Stage II example. First we compile the modified source with the normal C compiler to produce a bugged binary. We install this binary as the official C. We can now remove the bugs from the source of the compiler and the new binary will reinsert the bugs whenever it is compiled. Of course, the login command will remain bugged with no trace in source anywhere. So now there is a trojan'd version of cc. If you compile a clean version of cc, using the bad cc, you will get a bad cc. If you use the bad cc to compile the login program, it will have a backdoor. The source code for both backdoors no longer exists on the system. You can audit the source code of cc and login all you want, they are trustworthy. The compiler you use to compile your new compiler, is the untrustworthy bit, but you have no way to know it is untrustworthy, and no way to make a new compiler, without using the bad compiler. The moral is obvious. You can't trust code that you did not totally create yourself. (Especially code from companies that employ people like me.) No amount of source-level verification or scrutiny will protect you from using untrusted code. In demonstrating the possibility of this kind of attack, I picked on the C compiler. I could have picked on any program-handling program such as an assembler, a loader, or even hardware microcode. As the level of program gets lower, these bugs will be harder and harder to detect. A well installed microcode bug will be almost impossible to detect. Acknowledgment: I first read of the possibility of such a Trojan horse in an Air Force critique of the security of an early implementation of Multics. I can- not find a more specific reference to this document. I would appreciate it if anyone who can supply this reference would let me know.
