Introduction Hosts: MrX Dave Morriss We recorded this on Sunday May 26th 2024. We were pleased to discover that our favourite pub where we've had lunch in the past, The Steading, had not closed permanently following the sale of the premises. That's where we met for lunch. Thus the show title: The Steading is now back on course1. After lunch we as usual adjourned to Dave's Citroen car (Studio C) in the car park, and recorded a chat. Topics discussed YouTube channel recommendations (Dave) AT Restoration: Ahti is a furniture restorer from Estonia. The episodes contain no speech, just ambient sounds, but there is English text on-screen at times. Music is included for the final part where the item is shown in its before and after states. Shows some amazing skill in repairing all kinds of old furniture as well as some new builds. I found a surprise inside the 150 year old chair/armchair restoration: In this episode Ahti restores an armchair and shows the woodwork and upholstery required. Phil Vandelay: The channel is about designing and building cargo bikes, machines, furniture and more. The earlier shows contain no speech, just on-screen explanations. In later episodes there is more description and explanation. The level of engineering is high, and the host develops his metalworking workshop and skills as episodes progress. How to Build your own Cargo Bike (Short Version!): recent re-edit and re-release of the original. This seems to be the second cargo bike he has built, and later he builds yet another, this time electric. How to Build a DIY Cargo Bike (Plans available!): full version of the build. Ocean Conservation Namibia: A Namibia-based team rescuing Cape fur seals from entanglements in marine garbage. The seals are mainly on the beach and the team runs to intercept the ones they spot with garbage around them. They net them and remove whatever they have picked up and release the seals. In many cases the fishing line, net, or other junk has cut deeply into the seal's skin and muscle, and would kill them if not removed. Episodes are usually daily and mostly short. 34 Seals Rescued In One Day!: a recent episode, one of the longest. Digressions! Talking about varnishes for wood. Dave forgot the name of the varnish-like finish shellac, which is used in the technique of French Polishing. Woodwork: MrX made a stand for his music keyboard Dave made an unfashionable chair in the 1970s (similar in design and colour to the outer chairs in the image) Image copyright © https://www.design-market.co Grass-cutting, etc: Repairing a strimmer (aka string trimmer) Plastics: Bakelite was one of the earliest plastics Dave owns a valve radio which has a Bakelite case Computers owned over time (MrX) Sinclair ZX Spectrum: Released in 1982 Z80 (8-bit) CPU The original Spectrum had rubber-like keys MrX had a modified system with a keyboard upgrade - the DK'Tronics The Spectrum was used for Amateur Radio purposes: Morse code decoding Slow Scan Television (SSTV) RadioTeletype (RTTY) Dragon 32: Released in 1982 6809 (8-bit) CPU Better keyboard Centronics parallel (printer port) MrX had a pen plotter at one point, possibly an Epson Dave mentioned that he had used flat-bed pen plotters and large drum plotters at work The Dragon 32 was used for Packet Radio This is a data transfer protocol based on X.25 (called AX.25, Amateur X.25) Commodore Amiga: Released in 1985 Motorola 68000 series CPU, 16-bit and 32-bit models AmigaOS operating system; blitter AX.25 software Intel i386 PC Running Windows 3.1 PK232-MBX packet radio modem (manual) The PK232-MBX was similar to a telephone modem except it connected to radio. The MBX was a super deluxe model that had some extra features. It could do all the same things that the basic PK232 could do (see details from manual linked above) plus it could also do WeFax (WeatherFAX) and had a basic Packet-Radio mailbox facility. The two models could deal with morse code, Baudot and ASCII RadioTeletype (RTTY), AMTOR (Amateur Teleprinting Over Radio) and Packet-Radio, using in-built software. The connected radio would switch between transmit and receive to send and acknowledge packets of information. The computer was connected by serial RS232 connection. Basic commands were used to control the modem. Any computer capable of talking over RS232 could be used. Currently a Dell Optiplex ex business machine: 4GB of RAM and a Pentium Dual-Core E5500 CPU clocked at 2.8 GHz Ubuntu 18 LTS & Windows 7, needed in order to reprogram Amateur radios Digressions: Dave remembered seeing an example of the Nascom 1 at Lancaster University around 1978/79. This was a single board computer kit using the Z80 CPU. Comparing a VAX "mainframe" with a Raspberry Pi: Not simple! From 1987 Dave managed two clustered VAX 8700s. These were single CPU systems with a 32-bit word length and up to 512MB of memory. It's possible for a Raspberry Pi to emulate a VAX running the VMS operating system, though Dave has no direct experience. With the RPi 4 and 5 there's a good chance that performance compared to an actual VAX might be similar if not better. This is just guesswork however! Apollo Guidance Computer: MrX discusses the development of these systems at NASA, which had to be small and very reliable. Use of integrated circuits which were very expensive and variable in quality. Use of rejected chips in other projects so they were not wasted. Finding information about things from the 1970s and 1980s: It's surprisingly hard to find much about technology, IT and so forth from that era. Information that existed on paper, in newspapers and magazines from that time has apparently never been recorded and made searchable. Burroughs Corporation: Dave worked on a Burroughs B6930 mainframe in the early 1980s at Heriot-Watt University. The Burroughs terminals model TD830 ran on two coaxial cables to connect to the mainframe and to each other in a sort of "bus" configuration. Dave has a new PC waiting to be set up. It's from TUXEDO Computers in Germany. It's an AMD Ryzen 7000 Raspberry Pi development: MrX is having difficulty finding time to work on his. Dave has set up two RPi 4B systems which boot off USB SSDs, one Pi running Pi-Hole. He has further plans for both, but hasn't done much yet. Dave also has a RPi 5 with a Pimoroni card under it holding a 500GB NVME M.2 card. The plan is to boot it off this disk, but it needs a case and a means of mounting to a DIN rail. Various computer problems: Dave had problems after an upgrade of Debian Testing on his main desktop, since the previous of these shows. The upgrade left the PC in an unusable state with no desktop manager, and it took some time to repair it (installing and configuring from the console). MrX upgraded a Raspberry Pi successfully, then applied another upgrade which failed. He was able to revert to the previous state luckily, but still has an out of date OS. Dave's laptop running KDE Neon failed due to not upgrading it frequently enough, so in this case, since it had nothing of importance on it, he just installed Linux Mint over the top of it! MrX still has a usable Eee PC, though the battery has failed. This is the model 700. Dave also has a Eee PC, the 1000 model, but hasn't used it for a while. Steady as she goes - a Nautical expression. A cry to a helmsman to keep on the current course.↩︎

The 16:9 PODCAST IS SPONSORED BY SCREENFEED – DIGITAL SIGNAGE CONTENT Using data is pretty much integral to just about any ambitious and involved digital signage network being spun up these days, but for a lot of vendors and their customers, it's still a relatively new concept and approach. That's definitely not the case for the Toronto-area CMS software firm Omnivex, which has been around for more than 30 years and has always made data-driven communications central to what it does. More than 20 years ago, the core Omnivex solution included a module called DataPipe. I know, because I was using the thing way back then for a digital ad network I launched ... probably 10 years too early, but that's a story for another time. While a lot of its competitors have developed and marketed platforms that are pretty and loaded with bling, Omnivex has resolutely stuck to its technology guns with software that's quite involved and very powerful. The net result is Omnivex gets involved in a lot of the more complicated jobs in which real-time data, and the context it provides, shapes what shows up on screens. Airports, for example, are a very active vertical. I had a long, detailed chat with Neil Chatwood, a transplanted Brit who runs the global transport file for Omnivex. We could have gone on for hours, as he has a lot of insights about data, security, and programming content for large, very involved environments. Neil, thank you for joining me. For those people who don't know Omnivex, can you just give a quick rundown on the company?  Neil Chatwood: Yeah, for sure. So, Omnivex was established back in the dark ages of digital signage, 1991. It's a privately owned organization, just outside of Toronto, Ontario and Canada. Oh, come on. It's in Toronto. Like, Toronto goes on forever.  Neil Chatwood: Yeah, it's right. Pretty much right on the border. Well, it's on the subway line now. They've expanded the subway, so that finally happened.  Yeah, it's not like you see countryside on the other side of the parking lot though. Neil Chatwood: Not anymore. In the last 10 years, there's been a Vaughan skyline, as depressing as that may be. But yeah, I've been around a long time in a private family owned organization and it's really grown off the back of our focus on leveraging real time data, integrating with basically any system we could possibly think of. And that pedigree has kept us in the business for over 30 years now.  Yeah, I have a history in a network I started more than 20 years ago using Omnivex. So I was familiar with Omnivex products and datapipe and everything. So we were talking before we turned on the recording. I found it amusing that a lot of the software side of the industry has awakened to the idea of data integration and data handling for the last four or five years when it's something you were doing like 25 years ago.  Neil Chatwood: Yeah. Back in around 2009-2010 when a lot of the industry was yelling Content is King. Right. Don't say that.  Neil Chatwood: I know. You see. I do. Yeah, it's a classic. And our ownership at the time, you know, they like to have fun and they took that and changed it into Context as King and we've really kind of run with that since inception. But I joined the organization in 2010 and data and complexity is where we've always really hung our hat. We're a software vendor but the majority of our revenue comes from licensed sales. But we really do find ourselves in the trenches with our partners and our clients getting in there and providing pseudo consultancy on what data do you have in house?  Like, how has it been stored? What methods can we use? And figuring out the solution in parallel with all of the stakeholders, even though at the face of it we're just slinging CMS licenses. So that's our heritage and when I'm when I start talking to someone who's interested in looking at the market or you get a lead or you're talking to someone at a trade show, my advice is always to take a look at a bunch of companies. Take a bunch of companies, look at all these CMSs. In all the old guard, there's a good handful of companies that I might say some names, Navori, for example, StrataCash, Scala, right. They're all pretty old guard, when we talk about the digital signage industry.  I encourage people to take a look at all the products that are on the market and once you start to get those demos and you start to go through the sales process, you can really see the DNA of where that company's come from, right? Like, are they focused on a really pleasant UX/UI experience? Are they focused on performing high end post processing within the platform itself and are good at asset generation as opposed to creating it in a third party piece of kit and bringing it in. Our DNA has always been on the data side our position is that if you're going to make good images and assets that you're going to bring into the CMS, trying to ask a creative to use a tool, that's not something they're already comfortable with, you know you're kind of paddling upstream on that. So we've always taken the position of let people use the software that they're already comfortable with. Let's not introduce a knowledge gap, bring it in. And that leads us to, well, if we're not going to focus on the asset side, let's focus on the data side. So yeah, that's where we've come from. And it's where goals are set for in the future as well.  Well, when you have literally hundreds of software options out there these days and I would suspect most of them in some way say, yes, we do data handling, we have data integration, we have APIs or whatever it may be. How does an end user discern what's real versus just you the bare essentials? Neil Chatwood: That's a good question. When the user is going through that sales process and they're doing their comparisons, they have to show you it works right? Like, we're in an industry that is extremely visual, very creative. And you and I have been to a lot of trade shows and a lot of the DSEs in our time and if you're walking around there on setup day, I've seen plenty of CMS vendors running their showreel on windows media player, right. Before the crowds arrive and it's like, well if your stuff's that good, why are you using that? Like, why are you doing it that way? So if I was a buyer or if I was a third party consultant trying to guide someone through this, I'd be like the first couple of calls you're going to have with them. You're going to get the dog and pony show, right. They're going to show you all the sexy stuff, right? Oh yeah, all works great. Do you want to bring this plug in? Get your IT team involved, right? The people who know where your data lives and what format it's in, how accessible it is. And get them to sit down with the sales engineers of these CMS companies and get them to POC and get your data into their product, right? Most CMSs at this point, they're cloud hosting their software as a service, right? If they're sitting there and they're saying this is really easy. We can just go bing bong bop and it comes in, alright then show me. Just don't accept it at face value if you really want to dig into this stuff. I don't know any software vendor out there that isn't going to entertain the idea of a proof of concept or at least won't say, yeah, sure like any salesperson just wants to get the sale. Right.  So, if you've got this accessible data, right. Let's say it's up on Azure, right. It's some kind of blob storage or if it's accessible through an API. Can you just give me the keys? Like, let me in and I'll show you it in real time and then we'll bring it in. Once they can prove that to you, then it's not about data accessibility anymore. It's then you need to start looking into the assurances that they're going to be ethical and they're going to have the same levels of governance and control over that data that is being ingested into their system. That's where a lot of our focus is now. And you've really kind of touched on that with APIs. Back in the nineties, when we were asked to integrate with all these different data sources. We were lucky if there was documentation, it was probably RS232, serial cables.. David:That's a term I haven't heard in a long time. Neil Chatwood: Yeah. Using Telnet to get in. So like, a lot of the solution building was just kind of banging your head against the wall just to even access the data and make it legible to processing that data into information and then getting that information down onto the screen. That is less of a concern now because we're at the point where any data provider, they've probably got a fully or semi documented API or they've got an SDK, a software development kit where for the most part, if we're looking to POC a data integration. It probably takes us two to four hours, right? But based on how well documented it is, if the data structure is easy to work with and more often than not, the biggest part that takes the most time is liaising with the third party organization to let us in, right?  Because the client will say, Oh yeah.we use such and such for this and we're using this product for our bus timetables, our bus scheduling. Can you guys hit that? So it's like, well, there's a good chance we've already hit it because we've got clients there already but if we haven't, then we need to start up an engagement and start talking to that third party organization. This is the sticking point, right? Because when we start talking to that third party organization that controls that data, that the client is already paying for and leveraging it in house. Depending on the attitude and market position of that third party, they might not want to let us in, right? Like there's a bunch of organizations out there that sell digital signage as a value add, right? So, a good example of that would be, the historic vendors for flight information display systems, right? Screens in airports showing arrivals and departures. They sold data and the screen element was like, Oh, by the way, you probably want to show this on a screen, right? So we'll just sell you that too. It's a value add, it's not a true CMS. It's a point solution. So when we're engaging with that third party vendor, I'm often at the head end of this for transportation, I'm like, Hey, we're working on this project with a mutual client, they want us to get into your data. Is there any way you can provide a sandbox or some test keys so we can just prove this out? Depending on where they're at, they might not want to let us in. So, the sticking point becomes, then I have to go back to the client and say to the client, I don't wanna cause any friction here, but we can't get in without credentials and they're not giving us any. So can you please get involved? And those are the conversations where things start getting political. We're not looking to roll logs under our course friction anywhere. But as far as I'm concerned, your client's already paying for the data, right? Like if you know if you want to bolt on some charges for hey now you're using it for digital signage, so we want to charge you an extra 5k a year. That's on you. But as far as I'm concerned, an existing client is paying for the data, they want to use it this way. You're standing in the way of progress here. So, how do we deal with that? I spend so much time dealing with that now. And a reaction to that about five years ago, I started a scum works team internally. Here in order to proactively build data partnerships so that when a client says a key phrase, Everbridge is a good example, right. For mass emergency notification. So when a client says Everbridge, we don't have to go through an uncertain process of reaching out to someone we don't know, not knowing what their position is. It's like, we've actually already got this working somewhere else. We can get in here. I can show you an example of it already working or if you can give us access, we can actually prove it with your data. So that, yeah, that's the business. I just wanted to ask,  I've seen companies that talk in terms of what I call functionality apps so that they developed a data handshake with, as you said, Everbridge and then they sort of market that as an application, this is something that we can activate for you. Is that how you look at it? Or is that kind of a different angle?  Neil Chatwood: We look at it that way, conceptually because it's modularity, right? So, in our product, we're going to use a mechanism to reach out to that, that could be through some custom scripting or it could be within a product in our stable that has a full UI, in order to access that data. Like a good example would be, back in the day we had a via link for a via phone system. Right. So, that functionality that some organizations call them widgets, right. Where it's like, Hey, I just want to slot in this functionality. It's a couple of clicks. I put in my username, put in my password and away we go. We operate that in the backend of the system. But at this point, don't have a full kind of walkthrough where it's like, Hey, put in your Twitter username and password and away you go. Ours is a little bit more behind the curtain. We do it that way because we have user personalities. We actually used to use the Simpsons characters too, like, are we dealing with a bar? Are we dealing with Maggie? Like, who are we dealing with here? So those user profiles. It's like, you should be doing this, right? And if when we're looking at building out a data integration, that should really be set and forget it. There really is no reason to go in there on a regular basis and be changing that information or that query or the way we're massaging the data. So that is an administrative function, right? That is something that's behind the scenes. By virtue of that, we're probably dealing with someone who's a bit more technical, as a bit of an IT background. So, we have a relatively open system, right? So, whereas when we're dealing with widgets and a simplified user experience. Click this button, put username in, click this button, put your password and click this, or it comes on screen and now you can kind of like trim that down like that. That's what I've seen some CMSs do and I think that's a really light low friction way to get that data in there. We take the approach of like we're a toolkit. We're going to assume that our users and our clients and our channel are matching our products and our toolkit to the right levels of user. So, in the backend, it's like, here's a fully open interface that you can do whatever the heck you want with, we can give you some foundational building blocks or modules to enable and empower that user to take it where they want to take it. And that speaks to kind of one of our other positions in the industry where anyone who's been around kind of knows that Omnivex deals with relatively complex situations because we've got that wide open back end that frankly is quite and is a bit scary, right? To a user that just wants to change a welcome board or change some numbers that are on a restaurant board. So that's really not our target market, right? Our target market is predominantly enterprise level. They've got an in-house IT team or they've got a good system integrator involved where we can really get into the weeds on what data you have. Data has a cost, right? Well organizations are paying to cultivate it, gather it, store it in house. How do we make that data actionable by adding incremental value to it? That's what we're looking for. So when we go into a situation, we want to find those people, those stakeholders within the end client and within our channel to get into those deeper discussions on like, I know you want to point an arrow to the right but if we look at what data you've got in house, like, let's say, modern elevator system or a modern escalator system where we're able to tie into the back end of, Hey, on a Monday, this elevator serves floors 8 through 12.  But, on weekends or on bank holidays, that elevator is completely shut off. Then, I probably don't want that arrow to go right, when that elevator is offline. I want it to point straight ahead like a zero degrees rotation, right? Instead of 90 degrees rotation. So if we don't have an awareness of what data the client has and the client doesn't have the kind of persona or has the team in house that knows, how their systems work and how their architecture and what data they have, then they might not be the best fit for the kind of challenges we're looking to tackle. You're doing a lot more than changing a price or a soup of the day.  Neil Chatwood: Yeah, that's the table stakes, right? I mean honestly, it's a bad word in our industry, but If you really want it to go down, PowerPoint is able to do that now. Like you can integrate PowerPoint with Excel. So I know, ever since I've been in the industry, you're always kind of one step away from someone saying, well, why wouldn't I just use PowerPoint for that? It's like, well, you're missing a whole bunch of functionality on top of it. But fundamentally, any CMS worth its salt has two core elements that it needs to play with. It needs to play with data and it needs to bring in assets and basically import those two elements into a layout, right? So by that definition, can PowerPoint do it? Yeah, If we really boil it down but there's so much value on top of any of these systems. But getting to that data, exploring the data with the clients is where our ROI comes in and that's a scary term for a lot of people in this industry too. I honestly think digital signage was really looking for ROI metrics for what feels like 20 years, we were really struggling. We only really started to get metrics around that in certain fields. Right. So it's really easy to establish ROI when we've got a camera pointed to the audience, we're looking at expressions and demographics and we're triggering it and we're detecting when eyeballs are looking this way. So ROI on that is really easy. You want me to give you ROI on a wayfinding arrow changing from zero degrees to 90 degrees. That's going to be a bit more obfuscated but maybe you're going to see that down the road when you have an independent audit on your facility and your KPIs go shifted five points because your space is a lot more usable now. So, adding incremental value on that data is really what we're looking to do and you mentioned menu boards. Menu boards are a real quick win. It's very transparent, the value of that is very clear but when we start to talk around, passengers flow around an airport or like nudge theory, convincing people to move one way instead of another way because that benefits the operations of the environment. That is a little bit more tricky to prove ROI on but the humans walking around that space are going to have less friction and less stress while they're in there. But it really all comes down to weaponizing the data like how do we get the most out of it? How do we turn data into information?  I could ask a bunch of questions but we probably talked for about three hours. I'm curious about a big job that you were directly involved in and Omnivex was obviously directly involved in at Minneapolis airport which is considered one of the better airports on the planet now. What's all involved there? Because there's a lot of data handling and a lot more going on than just saying that the flight to Seattle is at gate 47.  Neil Chatwood: Yeah, there is a lot going on at MSP and just to give them a quick shout out, MSP just won the best airport in North America for the third year running. I think that came out a couple of days back and I think they've won it like seven times out of the last eight years. So, they've got a dedicated team in house that takes care of this stuff. And I really want to focus on not Omnivex for a second here because the airport deserves to be called out here and so do us. We've got a system integrator in there called radiant technology as well out of Columbus, Ohio. And the success there has really started with the vision of their CIO, Eduardo Valencia. He was directly inspired by sports stadiums, right? And he was personally quite frustrated when he went to a sports stadium. How come the puck goes in the net, the whole stadium changes color and everything goes whiz bang and all of a sudden I'm being advertised, Coca Cola and like why do my screens in my airport suck? But I'm able to see this when I go to a hockey game. So there's got it. So he used certain mechanisms to figure out what's going on in the industry and who's able to power these full experiences within a facility and thankfully led him to us. So it really started with that frustration and they took a strategic view at the airport where you'll hear Eduardo talk about it. The entire airport should just be treated as a single pane of glass and I should be able to control any screen in the airport any way that I want which is a great ambition and a lot of facilities, it's not just airports. A lot of facilities have a similar ambition and it's very easy to start with that dream but it's not going to happen unless you align resources in house. So, MSP have their own decision making panel for digital signage.  They've got a group in house that is responsible for pushing this forward. Nothing good, nothing worthwhile, nothing award winning happens by accident. Like, they've taken a real pragmatic approach to this. So, they took a look at their screen estate. They took a look at the use cases. They took a look at that data and they engaged that system integrator as I mentioned, Radiant to like all right, how do we make good on all this stuff? So, it started from the top which kept teams engaged. It kept them focused and that's why this is a success. So, a part of that with a foundational piece of technology in there. But we're really just a toolkit and it speaks to what I mentioned before about, Hey, our backend might be a little bit scary but you can do whatever the heck you want. That's the power of a toolkit. So, to go back to what you mentioned about that widget and that usability you can have a really like turbo linear workflow but that really hamstrings capabilities, right? So when you're making a product, you've got to decide which way you want to go?  Do I want to go a mile wide? And an inch deep or do I want to go real deep where the scary stuff lives? That's where we typically are. Where were the, you know, where were the angler fish? So, that was MSPs approach and that example I mentioned was about what the elevators are doing, what the escalators are doing. What's happening operationally right now within my airport. So that's where you start. Like what's happening right now. Okay. So what's happening now? Well, Delta airlines have these check-in counters open. So well, I know my building, I know where the check-in counters are. So the screens that are directly parallel at the curbside to those check-in counters, then let the people pulling up in their cars know, Hey, if you want to go Delta, there's a big Delta logo and it says open underneath it. Okay. Particularly airports that are dynamically assigning check in counters for smaller airlines, right?  Neil Chatwood: For sure. Yeah. Multi-use, environment. So, when we're, yeah. So there's always going to be situations where like, Oh yeah, that terminal that's United terminal, right? So like, there's no real variance there, but there's a whole bunch of smaller airlines and they call it common use. So, yeah. So, you know, we've got systems where, you know, let's say, you know, a smaller airline, you know, logs in like, you know, one example could be Flair. I don't, it's not around anymore. Right. But flair could log in. Okay. Well, they've only got two flights a day but they need to take over the ticket counter, they need to take over this gate temporarily. So when they log into the common use platform which is what's on those screens in front of those agents. When they log into that common use platform by virtue of them logging in, I know who they are, right? And I know that they work for Flare. So now it makes sense to change the screens that are physically behind that desk. Put up the default content for Flare right now because until this agent makes some decisions around, this screen is going to be the backdrop. This screen is going to be a priority checking or whatever. Maybe we just want to highlight that this is Flare's house now and then as they go through their login procedure the screens can be set up any way that they like and what we can do is we can provide dashboards and linear use case tools that makes it easy for that user. That's where things should be easy where someone's interacting with digital signage as this is not their job. Like their job is to make sure that they're processing passengers and getting them to where they need to be. There might be really high turnover. They have no interest or time to be trained on how to use a content management product. So it's like, look at that requirement. So what do I need to do? I probably need to present the screens that are behind them, I need to present to them the assets that are available to them and I need them to highlight which flight that they care about right now, that could all be manual. So, their experience is like, okay, I'm Neil, I've logged in, I'm at Flare, bang, screens change. Okay, I've got four screens behind me, what do you want on each one of these screens? I want to do image one, image three and image five. Instantly goes up on the screens behind them. All right, I'm done. So that's where it's really important to reduce that friction and make it easy. Not necessarily when we're setting up the data flow because again, I'm only really going to be setting up that data flow once and then maybe changing it when upstream data sources change. That experience for that airline agent, that is multiple times a day. That's where we need it to be frictionless, not on the data integration side. I think it's interesting with airports and other large footprint facilities like mass transport hubs, stadiums, multi use areas where there's a stadium, restaurants, residential, commercial on and on and on and airports in particular, I kind of see two threads to how experience works. I see these gorgeous, very ambitious, very expensive, digital art installations and giant LED walls in newly built airports and they talk about the experience of that and how people are going to feel good about flying and so on. But I see this whole other side and it is much more what you're talking about. A great experience in an airport is not being panicked, not being lost, not being delayed, not knowing where things are, all that sort of stuff. To me, that's a far more important experience, is that kind of how you see it and how some of your clients see it?  Neil Chatwood: There's a few hats I could wear on this. The first hat I'll wear is someone who wants to sell as many licenses as possible. I would rather they have a thousand flat panel screens, right. But that's not where the industry's going. Right. And the big reason for that is, we as an industry, we've watched the price of DV LEDs really just go through the floor to the point where there's real comparisons where it's like, is this a parity with like a 55 inch flat panel now For me to get a DVD, like a modular DVLED the same price. So that's a huge part of it. It's like the cost has finally come down to a point where it's reasonable at scale but a lot of it is also just straight up hype, right? Like airports, like anyone else have to sell and compete with other airports. And this is something that you don't really think about until you get into it but when you've got two airports that are within an hour's drive of each other. They're not only competing for passengers, they're competing for the airlines.  Yeah.  Neil Chatwood: Right? So it's like, If I'm courting with the idea of trying to bring a major airline two that are right next to each other but a good comparison would be like SFO in Oakland, right? So it's like, okay well, if I'm in Oakland, how do I convince people not to go over the bridge to SFO? I'd probably need the carriers that carry the most passengers.  San Jose? Neil Chatwood: Oh yeah. Good example. Yeah. So a lot of these big sexy installations are coming from, you've got to keep up with the Joneses. But also the price of DVLEDs is reasonable now. So there is that part of the market where it's all about the LinkedIn posts and the marketing and the wow factor. Yeah, you're exactly right. So there'll be like a handful of those within an airport, right? Like a good example would be, Nashville. We worked on a project with Nashville airport and the content that provided for that was, Gentle Home out of Montreal, where they all are. So, they provided that in an awesome job but that is just one. It's essentially two screens in probably in a state of, I think about 800 or so,  Something like that. Neil Chatwood: So, the big glitzy installations are now basically a requirement for any new build or any renovation for any airport. There's a couple of projects that I'm aware of that are really interesting. But in terms of decision making, like when I come back down to the fundamental goal of signage in general, not just digital, is to convey information quickly and clearly guide decision making in an environment. Is this generative AI artwork doing that? No, it's not going to help me get some flight on time but it might bring down my blood pressure a little bit, that's what these art installations are, right?  Like they're looking for an opportunity for facilities to express themselves, reinforce their branding, market the local area but also sell advertising which is a huge driving factor on some of these big installations too. So, there's very much like, let's call them the anchors, right? Like they're the anchor installations now where there's millions and millions of dollars being spent and then it's why I've always kind of enjoyed your outlook and your material Dave is like, the boring stuff and that's what I'm into as well and when I'm walking around the world. That's the stuff that I'm like, Oh, that is cool as hell. One of the best bits of boring signage at MSP is that good design is invisible, right? So, there is an underground walkway. It's not a walkway. It's more like a hallway but it's very much a liminal space and you're going under there. I'm trying to imagine putting my hand up. It's probably about 10 feet tall. So it's like, well, there's not much opportunity for overhead signage cause we can only really add probably about eight inches to this, like overhead. So, that team works with a display vendor and they put in, I think it's roughly around it's about a hundred or so feet wide. I know I'm probably over, I get it. It's probably about 80 feet wide. But 80 feet wide by about seven inches high.  So number one, okay, well, we're still compliant with safety and we've got this screen in this hallway now. What's great about it is it's pure wayfinding. All it does is just show people where they need to go. But upstream of this, like this very boring sign is I would estimate two and a half thousand data points. Yeah. In order to get the arrow point in the right way showing, Oh, you're looking for this airline or you're looking for a route with accessibility or you're looking for the TSA. When you add together the time to get to the queue, plus the queue time, which way should you go? What condition are the elevators in? What condition are the escalators in? Where as an airport, do I want to drive people right now, based on what's going on in my space? All that intelligence is above that sign, logically. But as a passenger, I look at it and I'm like, Oh yeah, I'm going with Air Canada today. Bump, I'm done. But the solution is so complex behind it but ultimately, it just means, Hey, this logo appears on screen and this arrow is at 220 degrees and that boils down to that. And I think that use case is beautiful like simplicity in design, it gets rid of the friction. It gets people where they need to be. That's what we're in this business for.  But the bottom line on that is it looks simple to the end user, to the observer, but there's a lot going on behind the curtains to make that work seamless.  Neil Chatwood: Yeah. Again, good design is invisible, right? Like you would have no idea the complexity that goes on with that screen. Like I said, we could talk for a very long time but we're already running longer than I usually do. So I got to wind this down, Neil, this has been great.  Neil Chatwood: Thanks, Dave. Omnivex has been around for a long time. I've been around a long time. You've been around a long time. I'm surprised we've not get to this earlier but thanks so much. I really respect Sixteen Nine and what you've done for the industry. And I encourage you to keep at it. We need a rational voice in this craziness.  All right. Well, thanks. Thanks again.  Neil Chatwood: All right. Thanks a lot, Dave. Take care.

Summary: In this episode, Daniel Newman and Mark Powell discuss various aspects of AV receivers (AVRs) and provide insights into choosing the right one for your needs. They cover topics such as comparing audio technologies, integration with control systems, and additional considerations when selecting an AVR. They emphasize the importance of working with a designer and asking the right questions to make informed decisions. They also caution against relying solely on built-in features like Bluetooth and Wi-Fi for music playback, recommending separate devices for better sound quality. The episode concludes with a reminder to subscribe, comment, and share the podcast. Takeaways When comparing audio technologies, it's important to work with a designer and gather opinions from experts to make informed decisions. Integration with control systems involves considering features like 12 volt triggers, RS232 connections, and network IP control. Built-in features like Bluetooth and Wi-Fi in AV receivers may not offer the best sound quality for music playback, so separate devices may be preferable.

EYE on NPI: Arduino Uno R4 Minima and Uno R4 WiFi Boards

This week's EYE ON NPI is a new spin on an old familiar classic, it's Arduino's UNO R4 Minima and R4 WiFi Boards (https://www.digikey.com/en/product-highlight/a/arduino/uno-r4-minima-and-r4-wifi-boards) now in stock at DigiKey for folks who want a 5V microcontroller board with classic UNO-compatibility but a ton more speed, flash and RAM! The UNO R4 comes in two flavors, the Minima (https://www.digikey.com/short/r70jbj93) is low cost, only $20, whereas the UNO R4 WiFi (https://www.digikey.com/short/qj072pnm) is $27.50 and adds WiFi and BLE via an ESP32-S3 plus a cute monochrome LED grid for scrolling messages or displaying status icons. This pair of dev boards look just like those classic Arduino boards you probably learned to code and hack on, they've been around for almost 20 years, the first board looked very similar, but had a RS232 serial port instead of USB, and all through-hole components (https://blog.arduino.cc/2021/12/09/one-board-to-rule-them-all-history-of-the-arduino-uno/). Through various iterations and improvements, the original board was redesigned to add USB and update to the ATmega168 with the Diecimila (https://docs.arduino.cc/retired/boards/arduino-diecimila) and then the ATmega328 plus auto-power-switching Duemilanove (https://docs.arduino.cc/retired/boards/arduino-duemilanove) in 2009. In 2010 the most popular Arduino to date was released, the UNO, which updated the USB port to use an ATmega16u2 and through various small revisions added the IOref pin to allow 3V power/logic and separate I2C pins since A4/A5 were no longer always connected to a TWI peripheral. Since about 2012, which was the release date of the UNO R3, not a lot has happened with that particular configuration/shape. Arduino the company has released a ton more boards but in different form factors, all available at DigiKey: Nano, Due, MKR, Portenta etc. (https://www.digikey.com/en/supplier-centers/arduino) and you should definitely check them out! But it's also a big deal when the main workhorse of the family gets a respin. Particularly since the new R4 takes a very different direction than the previous UNOs: instead of just upgrading the atmegaxx8 chipset, Arduino has gone with the totally different ARM Cortex-based RA4M series which we've covered on a previous EYE ON NPI (https://blog.adafruit.com/2023/05/25/eye-on-npi-renesas-ra4m1-microcontroller-series-eyeonnpi-digikey-renesasglobal-digikey-adafruit/) In that video we covered a lot about the chip itself so check it out if you're interested in the specifics of that chip family. The chip itself is a similar family to the ARM Cortex M0-based SAMD21 'Arduino Zero' (https://store-usa.arduino.cc/products/arduino-zero?selectedStore=us) but thanks to the Renesas version of this core, we now get the 5V-run RA4M. From Arduino's description, here are some of the updates: - Hardware compatibility with UNO form factor: The UNO R4 Minima maintains the same form factor, pinout, and 5 V operating voltage as its predecessor, the UNO R3. This ensures a seamless transition for existing shields and projects, leveraging the extensive and unique ecosystem already established for the Arduino UNO. - Expanded memory and faster clock: Prepare for more precise calculations and the ability to handle complex projects with ease. The UNO R4 Minima boasts increased memory and a faster clock speed, empowering you to tackle demanding tasks effortlessly. - Extra on-board peripherals: The UNO R4 Minima introduces a range of on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP. These additional components provide you with expanded capabilities and flexibility in your designs. - Extended 24 V tolerance: The UNO R4 Minima now supports a wider input voltage range, allowing power supplies up to 24 V. This enables seamless integration with motors, LED strips, and other actuators, simplifying your projects by utilizing a single power source. - SWD connector: Debugging is a critical aspect of any project. Simply connect an external debugger to the UNO R4 Minima and effortlessly monitor the inner workings of your system. Stay in control and gain valuable insights. - HID support: The UNO R4 Minima comes with built-in HID (Human Interface Device) support, enabling it to simulate a mouse or keyboard when connected to a computer via a USB cable. This convenient feature makes it a breeze to send keystrokes and mouse movements to a computer, enhancing usability and functionality. At $20 a piece, these new Arduino UNO R4s (https://www.digikey.com/short/qj072pnm) are a great price for the high quality you get from Arduino - and there's lots of them in stock at DigiKey for immediate shipment! Grab both the UNO R4 Minima (https://www.digikey.com/short/r70jbj93) and UNO R4 WiFi (https://www.digikey.com/short/qj072pnm), and they'll ship immediately so you can get started moving your 8-bit micro projects to Cortex-M4 by tomorrow afternoon

Inoffensive in every region of the world. Meeting me is a completely different story. Name is Trey. I have been listening to HPR for about a year and after hearing repeated pleas for episodes, I thought I would record some of my own. I cannot guarantee quality of production nor content, but I hope you find them entertaining. This episode is simply an introduction with a little bit of information about me My love of computers began 40 years ago when my parents scrimped and saved to purchase a Texas Instruments TI-99/4a computer. I began programming in BASIC, saving programs to audio cassette tapes. I remember buying magazines to get new programs to enter, save, edit, and turn into something different. Soon I expanded the computer to include 32K of RAM and an RS232 card which allowed me to connect a 300 BAUD modem and connect to bulletin board systems (BBS). BBS became my connection to the world. I later upgraded to a Commodore 64, which gave me a floppy disk. Much faster than saving to tape. I studied electronics & computers in college, then went to work for a large computer vendor, traveling all over fixing computers, networks, and peripherals. After about a decade, I joined a different company where I worked in systems administration and engineering, with a focus on information security. I have worked as security analyst, incident responder, security engineer, and security architect, then built out and managed the SOC for a large organization. Today, I am still focused on information security and I also dabble in clock repair, Ham radio, electronics, and photography. I may record some episodes on some of these topics in the future. Thank you for listening to me prattle on about myself, and have an awesome day.

Scanner School - Everything you wanted to know about the Scanner Radio Hobby

Today we're talking about a classic, the Uniden BC780XLT.  This radio came out in 2000 and it shook up the scanner radio market.  Learn why the power that was behind it made it a go-to scanner for many people at the time and what was available for this model on the aftermarket.    What You Learn in this Week’s Podcast: Learn what the BC780XLT could do right out of the box.  The BC780XLT was strictly analog. You can put a Motorola trunk system in the same bank as conventional frequencies.  You can't mix two trunk systems in the same bank but you can mix conventional and trunking together. This model allows you to search out CTCSS and DCS tones.  You can program 500 channels in 10 banks. It works well as a weather receiver You can program scan delays that are built-in per channel, and you can have a limit hold on each frequency. This scanner has channel alerts. A very cool feature is this scanner’s versatile RS232 serial port. You have a tape-out on the back of the radio Program searches are built-in. You can pre-program ten search ranges and have selectable step sizes. The display was revolutionary for the time. There were many aftermarket software options for this model. People took this scanner with them and actually used it as a portable radio.

Trip reports from the Essen Hackathon and BSDCam, CfT: ZFS native encryption and UFS trim consolidation, ZFS performance benchmarks on a FreeBSD server, how to port your OS to EC2, Vint Cerf about traceability, Remote Access console to an RPi3 running FreeBSD, and more. ##Headlines Essen Hackathon & BSDCam 2018 trip report Allan and Benedict met at FRA airport and then headed to the Air Rail terminal for our train to Essen where the Hackathon would happen over the weekend of Aug 10 - 12, 2018. Once there, we did not have to wait long until other early-arrivals would show up and soon we had about 10 people gathered for lunch. After buying some take-out pizzas and bringing it back to the Linuxhotel (there was a training still going on there so we could not get into our rooms yet), we sat in the sunny park and talked. More and more people arrived and soon, people started hacking on their laptops. Some people would not arrive until a few hours before midnight, but we already had a record appearance of 20 people in total. On Saturday, we gathered everyone in one of the seminar rooms that had rooms and chairs for us. After some organizational infos, we did an introductory round and Benedict wrote down on the whiteboard what people were interested in. It was not long until groups formed to talk about SSL in base, weird ZFS scrubs that would go over 100% completion (fixed now). Other people started working on ports, fixing bugs, or wrote documentation. The day ended in a BBQ in the Linuxhotel park, which was well received by everyone. On Sunday, after attendees packed up their luggage and stored it in the seminar room, we continued hacking until lunchtime. After a quick group picture, we headed to a local restaurant for the social event (which was not open on Saturday, otherwise we would have had it then). In the afternoon, most people departed, a good half of them were heading for BSDCam. Commits from the hackathon (the ones from 2018) Overall, the hackathon was well received by attendees and a lot of them liked the fact that it was close to another BSD gathering so they could nicely combine the two. Also, people thought about doing their own hackathon in the future, which is an exciting prospect. Thanks to all who attended, helped out here and there when needed. Special Thanks to Netzkommune GmbH for sponsoring the social event and the Linuxhotel for having us. Benedict was having a regular work day on Monday after coming back from the hackathon, but flew out to Heathrow on Tuesday. Allan was in London a day earlier and arrived a couple of hours before Benedict in Cambridge. He headed for the Computer Lab even though the main event would not start until Wednesday. Most people gathered at the Maypole pub on Tuesday evening for welcomes, food and drinks. On Wednesday, a lot of people met in the breakfast room of Churchill College where most people were staying and went to the Computer Lab, which served as the main venue for BSDCam, together. The morning was spend with introductions and collecting what most people were interested in talking. This unconference style has worked well in the past and soon we had 10 main sessions together for the rest of this and the following two days (full schedule). Most sessions took notes, which you can find on the FreeBSD wiki. On Thursday evening, we had a nice formal dinner at Trinity Hall. BSDCam 2018 was a great success with a lot of fruitful discussions and planning sessions. We thank the organizers for BSDCam for making it happen. A special mentions goes out to Robert Watson and his family. Even though he was not there, he had a good reason to miss it: they had their first child born at the beginning of the week. Congratulations and best wishes to all three of them! ###Call for Testing: ZFS Native Encryption for FreeBSD A port of the ZoL (ZFS-on-Linux) feature that provides native crypto support for ZFS is ready for testing on FreeBSD Most of the porting was done by sef@freebsd.org (Sean Eric Fagan) The original ZoL commit is here: https://github.com/zfsonlinux/zfs/pull/5769/commits/5aef9bedc801830264428c64cd2242d1b786fd49 For an overview, see Tom Caputi’s presentation from the OpenZFS Developers Summit in 2016 Video: https://youtu.be/frnLiXclAMo Slides: https://drive.google.com/file/d/0B5hUzsxe4cdmU3ZTRXNxa2JIaDQ/view?usp=sharing WARNING: test in VMs or with spare disks etc, pools created with this code, or upgraded to this version, will no longer be importable on systems that do not support this feature. The on-disk format or other things may change before the final version, so you will likely have to ‘zfs send | zfs recv’ the data on to a new pool Thanks for testing to help this feature land in FreeBSD iXsystems ###Call for Testing: UFS TRIM Consolidation Kirk Mckusick posts to the FreeBSD mailing list looking for testers for the new UFS TRIM Consolidation code When deleting files on filesystems that are stored on flash-memory (solid-state) disk drives, the filesystem notifies the underlying disk of the blocks that it is no longer using. The notification allows the drive to avoid saving these blocks when it needs to flash (zero out) one of its flash pages. These notifications of no-longer-being-used blocks are referred to as TRIM notifications. In FreeBSD these TRIM notifications are sent from the filesystem to the drive using the BIODELETE command. Until now, the filesystem would send a separate message to the drive for each block of the file that was deleted. Each Gigabyte of file size resulted in over 3000 TRIM messages being sent to the drive. This burst of messages can overwhelm the drive’s task queue causing multiple second delays for read and write requests. This implementation collects runs of contiguous blocks in the file and then consolodates them into a single BIODELETE command to the drive. The BIODELETE command describes the run of blocks as a single large block being deleted. Each Gigabyte of file size can result in as few as two BIODELETE commands and is typically less than ten. Though these larger BIODELETE commands take longer to run, they do not clog the drive task queue, so read and write commands can intersperse effectively with them. Though this new feature has been throughly reviewed and tested, it is being added disabled by default so as to minimize the possibility of disrupting the upcoming 12.0 release. It can be enabled by running `sysctl vfs.ffs.dotrimcons=1’’. Users are encouraged to test it. If no problems arise, we will consider requesting that it be enabled by default for 12.0. This support is off by default, but I am hoping that I can get enough testing to ensure that it (a) works, and (b) is helpful that it will be reasonable to have it turned on by default in 12.0. The cutoff for turning it on by default in 12.0 is September 19th. So I am requesting your testing feedback in the near-term. Please let me know if you have managed to use it successfully (or not) and also if it provided any performance difference (good or bad). To enable TRIM consolidation usesysctl vfs.ffs.dotrimcons=1’ There is also a diff that adds additional statistics: https://lists.freebsd.org/pipermail/freebsd-current/2018-August/070798.html You can also watch the volume and latency of BIODELETE commands by running gstat with the -d flag ##News Roundup ZFS performance Aravindh Sampathkumar, a Performance Engineer and Sysadmin posts some simple benchmarks he did on a new ZFS server This is NOT an all-in post about ZFS performance. I built a FreeBSD+ZFS file server recently at work to serve as an offsite backup server. I wanted to run a few synthetic workloads on it and look at how it fares from performance perspective. Mostly for curiosity and learning purposes. As stated in the notes about building this server, performance was not one of the priorities, as this server will never face our active workload. What I care about from this server is its ability to work with rsync and keep the data synchronised with our primary storage server. With that context, I ran a few write tests to see how good our solution is and what to expect from it in terms of performance. The article then uses FIO to do some benchmarks. As the author did, make sure you match the FIO block size to the ZFS record size to avoid write amplification. Either tune FIO or adjust the recordsize property in ZFS You also want to consider compression and cache effects Write Performance: Incompressible: 1600-2600 MB/s, Compressible: 2500-6600 MB/s Another over 1200 MB/s is enough to keep your 10 gigabit network saturated The increased latency that is seen with higher number of writers working, may be the result of the ZFS backpressure system (the write throttle). There is some tuning that can be done there. Specifically, since this machine has 768 GB of ram, you might allow more than 4GB of dirty data, which would mean you’d be able to write larger batches and not have to push back while you wait for a transaction group to flush when dealing with gigabytes/sec of writes ###How to port your OS to EC2 Colin Percival reflects on his FreeBSD on EC2 maintainership efforts in his blog: I’ve been the maintainer of the FreeBSD/EC2 platform for about 7.5 years now, and as far as “running things in virtual machines” goes, that remains the only operating system and the only cloud which I work on. That said, from time to time I get questions from people who want to port other operating systems into EC2, and being a member of the open source community, I do my best to help them. I realized a few days ago that rather than replying to emails one by one it would be more efficient to post something publicly; so — for the benefit of the dozen or so people who want to port operating systems to run in EC2, and the curiosity of maybe a thousand more people who use EC2 but will never build AMIs themselves — here’s a rough guide to building EC2 images. Before we can talk about building images, there are some things you need: Your OS needs to run on x86 hardware. 64-bit (“amd64”, “x86-64”) is ideal, but I’ve managed to run 32-bit FreeBSD on “64-bit” EC2 instances so at least in some cases that’s not strictly necessary. You almost certainly want to have drivers for Xen block devices (for all of the pre-Nitro EC2 instances) or for NVMe disks (for the most recent EC2 instances). Theoretically you could make do without these since there’s some ATA emulation available for bootstrapping, but if you want to do any disk I/O after the kernel finishes booting you’ll want to have a disk driver. Similarly, you need support for the Xen network interface (older instances), Intel 10 GbE SR-IOV networking (some newer but pre-Nitro instances), or Amazon’s “ENA” network adapters (on Nitro instances), unless you plan on having instances which don’t communicate over the network. The ENA driver is probably the hardest thing to port, since as far as I know there’s no way to get your hands on the hardware directly, and it’s very difficult to do any debugging in EC2 without having a working network. Finally, the obvious: You need to have an AWS account, and appropriate API access keys. Building a disk image Building an AMI I wrote a simple tool for converting disk images into EC2 instances: bsdec2-image-upload. It uploads a disk image to Amazon S3; makes an API call to import that disk image into an EBS volume; creates a snapshot of that volume; then registers an EC2 AMI using that snapshot. To use bsdec2-image-upload, you’ll first need to create an S3 bucket for it to use as a staging area. You can call it anything you like, but I recommend that you Create it in a “nearby” region (for performance reasons), and Set an S3 “lifecycle policy” which deletes objects automatically after 1 day (since bsdec2-image-upload doesn’t clean up the S3 bucket, and those objects are useless once you’ve finished creating an AMI). Boot configuration Odds are that your instance started booting and got as far as the boot loader launching the kernel, but at some point after that things went sideways. Now we start the iterative process of building disk images, turning them into AMIs, launching said AMIs, and seeing where they break. Some things you’ll probably run into here: EC2 instances have two types of console available to them: A serial console and an VGA console. (Or rather, emulated serial and emulated VGA.) If you can have your kernel output go to both consoles, I recommend doing that. If you have to pick one, the serial console (which shows up as the “System Log” in EC2) is probably more useful than the VGA console (which shows up as “instance screenshot”) since it lets you see more than one screen of logs at once; but there’s a catch: Due to some bizarre breakage in EC2 — which I’ve been complaining about for ten years — the serial console is very “laggy”. If you find that you’re not getting any output, wait five minutes and try again. You may need to tell your kernel where to find the root filesystem. On FreeBSD we build our disk images using GPT labels, so we simply need to specify in /etc/fstab that the root filesystem is on /dev/gpt/rootfs; but if you can’t do this, you’ll probably need to have different AMIs for Nitro instances vs. non-Nitro instances since Xen block devices will typically show up with different device names from NVMe disks. On FreeBSD, I also needed to set the vfs.root.mountfrom kernel environment variable for a while; this also is no longer needed on FreeBSD but something similar may be needed on other systems. You’ll need to enable networking, using DHCP. On FreeBSD, this means placing ifconfigDEFAULT=“SYNCDHCP” into /etc/rc.conf; other systems will have other ways of specifying network parameters, and it may be necessary to specify a setting for the Xen network device, Intel SR-IOV network, and the Amazon ENA interface so that you’ll have the necessary configuration across all EC2 instance types. (On FreeBSD, ifconfigDEFAULT takes care of specifying the network settings which should apply for whatever network interface the kernel finds at boot time.) You’ll almost certainly want to turn on SSH, so that you can connect into newly launched instances and make use of them. Don’t worry about setting a password or creating a user to SSH into yet — we’ll take care of that later. EC2 configuration Now it’s time to make the AMI behave like an EC2 instance. To this end, I prepared a set of rc.d scripts for FreeBSD. Most importantly, they Print the SSH host keys to the console, so that you can veriy that they are correct when you first SSH in. (Remember, Verifying SSH host keys is more important than flossing every day.) Download the SSH public key you want to use for logging in, and create an account (by default, “ec2-user”) with that key set up for you. Fetch EC2 user-data and process it via configinit to allow you to configure the system as part of the process of launching it. If your OS has an rc system derived from NetBSD’s rc.d, you may be able to use these scripts without any changes by simply installing them and enabling them in /etc/rc.conf; otherwise you may need to write your own scripts using mine as a model. Firstboot scripts A feature I added to FreeBSD a few years ago is the concept of “firstboot” scripts: These startup scripts are only run the first time a system boots. The aforementioned configinit and SSH key fetching scripts are flagged this way — so if your OS doesn’t support the “firstboot” keyword on rc.d scripts you’ll need to hack around that — but EC2 instances also ship with other scripts set to run on the first boot: FreeBSD Update will fetch and install security and critical errata updates, and then reboot the system if necessary. The UFS filesystem on the “boot disk” will be automatically expanded to the full size of the disk — this makes it possible to specify a larger size of disk at EC2 instance launch time. Third-party packages will be automatically fetched and installed, according to a list in /etc/rc.conf. This is most useful if configinit is used to edit /etc/rc.conf, since it allows you to specify packages to install via the EC2 user-data. While none of these are strictly necessary, I find them to be extremely useful and highly recommend implementing similar functionality in your systems. Support my work! I hope you find this useful, or at very least interesting. Please consider supporting my work in this area; while I’m happy to contribute my time to supporting open source software, it would be nice if I had money coming in which I could use to cover incidental expenses (e.g., conference travel) so that I didn’t end up paying to contribute to FreeBSD. Digital Ocean https://do.co/bsdnow ###Traceability, by Vint Cerf A recent article from the August issue of the Communications of the ACM, for your contemplation: At a recent workshop on cybersecurity in the U.K., a primary topic of consideration was how to preserve the freedom and openness of the Internet while protecting against the harmful behaviors that have emerged in this global medium. That this is a significant challenge cannot be overstated. The bad behaviors range from social network bullying and misinformation to email spam, distributed denial of service attacks, direct cyberattacks against infrastructure, malware propagation, identity theft, and a host of other ills requiring a wide range of technical and legal considerations. That these harmful behaviors can and do cross international boundaries only makes it more difficult to fashion effective responses. In other columns, I have argued for better software development tools to reduce the common mistakes that lead to vulnerabilities that are exploited. Here, I want to focus on another aspect of response related to law enforcement and tracking down perpetrators. Of course, not all harms are (or perhaps are not yet) illegal, but discovering those who cause them may still be warranted. The recent adoption and implementation of the General Data Protection Regulation (GDPR) in the European Union creates an interesting tension because it highlights the importance and value of privacy while those who do direct or indirect harm must be tracked down and their identities discovered. In passing, I mention that cryptography has sometimes been blamed for protecting the identity or actions of criminals but it is also a tool for protecting privacy. Arguments have been made for “back doors” to cryptographic systems but I am of the opinion that such proposals carry extremely high risk to privacy and safety. It is not my intent to argue this question in this column. What is of interest to me is a concept to which I was introduced at the Ditchley workshop, specifically, differential traceability. The ability to trace bad actors to bring them to justice seems to me an important goal in a civilized society. The tension with privacy protection leads to the idea that only under appropriate conditions can privacy be violated. By way of example, consider license plates on cars. They are usually arbitrary identifiers and special authority is needed to match them with the car owners (unless, of course, they are vanity plates like mine: “Cerfsup”). This is an example of differential traceability; the police department has the authority to demand ownership information from the Department of Motor Vehicles that issues the license plates. Ordinary citizens do not have this authority. In the Internet environment there are a variety of identifiers associated with users (including corporate users). Domain names, IP addresses, email addresses, and public cryptography keys are examples among many others. Some of these identifiers are dynamic and thus ambiguous. For example, IP addresses are not always permanent and may change (for example, temporary IP addresses assigned at Wi-Fi hotspots) or may be ambiguous in the case of Network Address Translation. Information about the time of assignment and the party to whom an IP address was assigned may be needed to identify an individual user. There has been considerable debate and even a recent court case regarding requirements to register users in domain name WHOIS databases in the context of the adoption of GDPR. If we are to accomplish the simultaneous objectives of protecting privacy while apprehending those engaged in harmful or criminal behavior on the Internet, we must find some balance between conflicting but desirable outcomes. This suggests to me that the notion of traceability under (internationally?) agreed circumstances (that is, differential traceability) might be a fruitful concept to explore. In most societies today, it is accepted that we must be identifiable to appropriate authorities under certain conditions (consider border crossings, traffic violation stops as examples). While there are conditions under which apparent anonymity is desirable and even justifiable (whistle-blowing, for example) absolute anonymity is actually quite difficult to achieve (another point made at the Ditchley workshop) and might not be absolutely desirable given the misbehaviors apparent anonymity invites. I expect this is a controversial conclusion and I look forward to subsequent discussion. ###Remote Access Console using FreeBSD on an RPi3 Our friend, and FOSDEM Booth Neighbour, Jorge, has posted a tutorial on how he created a remote access console for his SmartOS server and other machines in his homelab Parts: Raspberry Pi 3 B+ NavoLabs micro POE Hat FT4232H based USB-to-RS232 (4x) adapter Official Raspberry Pi case (optional) Heat-sink kit (optional) USB-to-TTL adaptor (optional) Sandisk 16Gb microSD For the software I ended up using conserver. Below is a very brief tutorial on how to set everything up. I assume you have basic unix skills. Get an RPi3 image, make some minor modifications for RPi3+, and write it to the USB stick Configure FreeBSD on the RPi3 Load the ‘muge’ Ethernet Driver Load USB serial support Load the FTDI driver Enable SSHd and Conserver Configure Conserver Setup log rotation Start Conserver And you’re good to go A small bonus script I wrote to turn on the 2nd LED on the rPI once the system is booted, it will then blink the LED if someone is connected to any of the consoles. There is also a followup post with some additional tips: https://blackdot.be/2018/08/freebsd-uart-and-raspberry-pi-3-b/ ##Beastie Bits Annual Penguin Races Mscgen - Message Sequence Chart generator This patch makes FreeBSD boot 500 - 800ms faster, please test on your hardware FreeBSD’s arc4random() replaced with OpenBSD ChaCha20 implementation MeetBSD Devsummit open for registrations New Podcast interview with Michael W. Lucas Tarsnap ##Feedback/Questions We need more feedback emails. Please write to feedback@bsdnow.tv Additionally, we are considering a new segment to be added to the end of the show (to make it skippable), where we have a ~15 minute deep dive on a topic. Some initial ideas are on the Virtual Memory subsystem, the Scheduler, Capsicum, and GEOM. What topics would you like to get very detailed explanations of? Many of the explanations may have accompanying graphics, and not be very suitable for audio only listeners, that is why we are planning to put it at the very end of the episode. Send questions, comments, show ideas/topics, or stories you want mentioned on the show to feedback@bsdnow.tv

Throw out your breadboard! Dr. Duino: An Arduino Shield for debugging and developing Arduino projects

In the last couple of episodes we have talked about Arduino shields and breakout boards. In this video, we will review a specific Arduino shield that makes developing projects and debugging sketches on the Arduino extremely easy - it's called Dr. Duino.Arduino Shield for Arduino Shields The Dr. Duino is an Arduino Shield. As would expect, it fits snuggly on top of the Arduino headers and has pin headers of it's own, which can easily accept a shield on top. The first thing you notice about Dr. Duino is that it's built like a doughnut - it's got a giant hole in the middle! (FYI - It does not taste like said pastry…) There are a couple reasons for this form factor, but foremost is that even after you stack another shield on top of Dr. Duino, you still have easy physical access to all its resources. Dr. Duino Hardware Resources What resources are we talking about? Dr. Duino has 4 momentary pushbuttons, 5 LEDs, 6 potentiometers, an RS232 connector, and a bunch of access points for 5 volts, 3.3 volts and ground, oh yeah, and a siren (piezo buzzer). So how do you access these resources and why would you even care to? Both great questions! The core feature that allows us to use all the hardware I just talked about are groups of three “jumper” pins that surround the board. Almost every pin on the Arduino is associated with a set of these jumper pins. The middle pin is connected directly to the Arduino pin. The pin on the left is connected to the pin header on top of the Dr. Duino. The pin on the right is connected to the one of the hardware resources on the Dr. Duino board. With each set of these three jumper pins we get a plastic encased "jumper" - it fits snug on top 2 pins, and electrically connects them together. For every Arduino pin that has associated Dr. Duino jumper pins we have 2 decisions: 1) We can route the Arduino pin to the shield above by connecting the center pin to the jumper pin on the left. This passes the Arduino pin directly up to the shield if you have one attached, bypassing the Dr. Duino. 2) Or, we can route the Arduino pin to the resource on the Dr. Duino shield, bypassing the shield above. Each pin has a different "resource" or piece of hardware that you can use. Here is a quick mnemonic for remembering how to place the “jumper” on the “jumper pins” – Left goes Up (to the shield above), Right goes to Down (to the Dr. Duino). Digital pins 5, 6, 10, 11, and 13 have LEDs attached. Digital Pins 7, 8, 9 and 12 have momentary pushbuttons attached. Analog pins A0 - A5 have potentiometers attached and digital pin 3 is attached to the piezo buzzer. All these asset are extremely helpful. For example, let's say I am prototyping with a motor shield. What I want is for every time I press a button, then a servo moves 180 degrees. Instead of having to bust out a breadboard and jumper wires, I simply move a jumper on the Dr. Duino and I now have a preinstalled button. As long as the shield is not using that pin for anything, it's fair game to route that pin to the Dr. Duino. Or, maybe I want to turn a potentiometer to get the servo to move. Once again - scrap the breadboard - just move a jumper on one of the analog pins and you have a built in potentiometer - in fact, every analog pin has its own dedicated potentiometer! Trying to put 6 potentiometers on a breadboard and run jumpers is a major pain - having these built right in and so compact is great. Potentiometers are great for simulating sensor inputs too. Say you are developing a project that lights up LEDs based on inputs from a pressure sensor - but you don't have the sensor yet. No worries - just use the potentiometer built in to the Dr. Duino to simulate the input from the pressure sensor. Another great resource is the piezo buzzer. Most of us get used to using the serial window to debug our sketches. For example - we use the Serial .print() function to send a value to the serial monitor window when some threshold is met. What this ends up doing is dividing our visual attention from the Arduino to the computer monitor. With the piezo buzzer, you can get the same information, but be able to look at your Arduino - it allows you to incorporate more of your senses into the debugging process. All of these features add up to a great little development package - it's like a breadboard full of components all connected on a handy shield. So if I am traveling I don’t have to pack away a bunch of pieces-parts, I can just throw the Dr. Duino in with my Arduino and go for it. A Tool for Learning Arduino Code Another great use of these resources is when you are learning to use Arduino. If you are really trying to jump right into the code, then setting up the circuit can sometimes be a hassle, even if its just a button and an LED. (Yes - I am that lazy!) With Dr. Duino you can work through practically every sketch in the examples section of the Arduino IDE with only some minor code changes (mostly pin designations changes), without having to add a single piece of hardware. That’s a time saver (especially when it’s hard enough to carve out time to learn). Especially if having to place the components just feels like another barrier to practicing your Arduino coding. A Debugging Tool So far, most of my love for the Dr. Duino has come from this development aspect, but the Dr. Duino has actually been designed to help you debug your sketches when using shields. Microcontrollers (like the Arduino uses) are truly at the threshold of hardware and software. The more you know about both the physical and virtual, the better off you will be. Here in also lies a challenge – you can screw up both the hardware and the software. A big part of debugging your work is tracking down where the issue exists – is it the copper or code? (Or both !@#$) The Dr. Duino’s key feature of being able to direct an Arduino pin to or away from a shield you are using enables you to more quickly establish the starting point of debugging. Once you master how the rerouting works, the Dr. Duino will be a go-to shield for developing and debugging. With such a diverse set of applications it’s no wonder Arduino continues to grow wildly popular. Shields like the Dr. Duino make it that much more fun to use Arduino as a rapid prototyping tool. Special Bonus If you are interested in getting your hands on a Dr Duino, you can buy them directly from the Dr. Duino website. The creator of Dr. Duino (Guido Bonelli) has been kind enough to offer Open Source Hardware Group readers a free shipping code. Free Shipping Code: OSHWG_RULES (So true…)

The CAT interface

Foundations of Amateur Radio Today's Amateur Radio is less like the valve or transistor based radio and more like a computer. So much so that most radios today have a mechanism to connect the radio to a computer. This mechanism is called a Computer Aided Tuning interface, or CAT interface. It's a mechanism that's used to allow two way control information to be shared between the radio and a computer. This interaction is a serial connection, generally something called RS232. This is a standard that was developed in 1962 and it specifies things like timing, voltages and other attributes. The electronics from that era don't look much like the ones of today and most of the challenges with getting this stuff to work is related directly to these differences. It should come as no surprise that each manufacturer has their own take on what this whole contraption looks like and most of this technology is not directly compatible across radios. So, let's imagine that you've got a radio and a computer and they're physically connected to each other using a CAT interface of some description. We then need to make sure that things like the speed of both ends is the same, that is, the BAUD rate is the same. Also we need to check that the number of bits, stop bits and parity are also correct. If this sounds a little like 1980's modem talk, you'd be correct. The radio is presenting itself to the computer as a serial device, just like a dial-up modem does. If you've not seen this, just think of it as if the numbers at both ends need to match. Often the radio will have a standard setting, which you should use as a starting point. Now, I'm going to skip over things like IRQs and port addresses, not because it's simple, but because it might work out of the box, or it might cause you to lose hair. If it's the latter, you're going to need to do some IT support and this is about radios and not about computers. I'm also going to gloss over the problem that most modern computers don't have an actual serial port any more, most have something called USB which requires an adapter and software for the adapter, another potential minefield to traverse. Now comes the bit where it all works, right? Nope. Not yet. Next you need to have software that knows how to talk to your radio. It may be programming software, specifically to configure your radio, or it may be generic logging software that reads what mode and frequency you're on and puts that in your log, or it may be something that knows how to correct the frequency of your radio to deal with the Doppler effect of an overflying satellite. In each case, you'll need to tell your software several things. The most basic one of those is the port number. That is, of all of the serial ports on your computer, which one is connected to your radio? Seeing that all Amateur Radio manufacturers agree on everything, all actual control codes and responses are the same across all radios. Oh wait, nope, that's not true. They're not even the same across the same brand, so you'll also need to tell your software which actual radio you're using, which is the perfect opportunity to learn that your shiny new radio doesn't yet exist within the software. So, when you start looking at the CAT interface, you now know that this is a thing that's going to require some homework and planning. To make digital modes work, you need an audio interface to go with the CAT interface, which a whole different set of fun and games, including ground loops, impedance matching, levels, feedback and distortion. Now, if you thought that you and I took a lovely walk through the deep arcane world of serial computer interfaces, wrap your head around this. When we use the current crop of software defined radios, we replicate all of this, both CAT and audio interfaces with virtual versions of cables, BAUD rates and port numbers. Suffice to say, I don't have words. I should add that all of what I've said is just so you get an idea that there is a chain of stuff that needs to work and that any one of these being incorrect will cause none of it to work. So, when you're doing this in your own shack, start at the beginning, get the cable working, set the speed and bits, set the port, pick the radio and cross your fingers. It's not trivial, but it's worth it. I'm Onno VK6FLAB

The TI-99/4A - Tech Specs, Peripherals, Modern Upgrades with Tursi This show is a continuation of the on-going series about the TI-99/4A computer.  In the last couple of episodes, I had TI-99 fans Jim Fetzner and Mark Wills on the show and interviewed them about their experiences with the TI-99 and then we covered the history of the machine.  In this show, I have a new co-host, Mike Brent, better known as Tursi or Harmless Lion, the creator of the Classic 99 emulator and so much more.  After a short interview with Tursi, we discuss the technical aspects of the TI-99, including the tech specs, peripherals, modern upgrades, and connectivity to modern computers.  It’s an information-filled show, so I hope you enjoy it. Before we get into that, I’ll discuss a few new vintage computer-related acquisitions that have come my way, give you the scoop on upcoming shows, and share with you a few pieces of feedback I’ve received about the show from listeners.

AT DT retrobits podcast CONNECT 9600 Welcome to show #007!  Today's podcast focuses on making the connection between retro computers and modern-day PCs. Topics and links discussed in the podcast... E-mails came in from Alan, Ryan and Dave with Libsyn - thanks!  Always great to get e-mails regarding the show. The C64 Take Away Podcast is, in their words, "Your regular fix of Commodore 64 tunes, remixes, news and whatever takes our fancy. Produced and presented by Jan Lund Thomsen of Remix.Kwed.Org fame".  Also check out the parent site, Slay Radio, for streaming retro remixes at various bandwidths. Juiced.GS is a quarterly Apple II publication. The X1541 series of cables connect Commodore computers and disk drives to the parallel port of a standard PC. The Apple Disk Transfer program lets you take Apple disk images, and using a serial cable and real Apple II, turn those images into real disks! Good old RS232 serial ports have been around forever, and can hook up the old and new with relative ease.  Here's a site with lots of technical goodness on RS232. The 64HDD software package, both free and professional versions, allow you to turn a DOS-based PC into a floppy and hard drive emulator for Commodore computers. The Star Commander is a DOS shell program that can handle C64 disk formats, and permits copying of files and disk images to a Commodore drive connected with one of the X cables. The SIO2PC cable connects Atari computers to a PC.  The PC can emulate storage, printers, and more. The Catweasel series of disk controllers are used in modern PCs, and can make your 3.5 and 5.25 drives capable of reading and writing foreign disk formats for retro computer systems.  Information on various Catweasel models is available at the Individual Computers site.
