Happy LLama 3 day folks! After a lot of rumors, speculations, and apparently pressure from the big Zuck himself, we finally can call April 18th, 2024, LLaMa 3 day! I am writing this, from a lobby of the Mariott hotel in SF, where our annual conference is happening called Fully Connected, and I recorded today's episode from my hotel room. I really wanna shout out how awesome it was to meet folks who are listeners of the ThursdAI pod and newsletter subscribers, participate in the events, and give high fives. During our conference, we had the pleasure to have Joe Spisak, the Product Director of LLaMa at Meta, to actually announce LLaMa3 on stage! It was so exhilarating, I was sitting in the front row, and then had a good chat with Joe outside of the show

Apple presentó dos nuevos planes de almacenamiento, 6TB por $29.99 y 12TB por $59.99.

Horacio y yo hacemos un viaje en el mapa de los medios para hacer una parada en LatinUS. Hace algunos días se dio a conocer el hackeo de la SEDENA que implicó la filtración de 6TB de datos. Loret de Mola tuvo la primicia en LatinUS. ¿Hubo algo interesante y nuevo?

De los 6TB de información hackeados, la 4T dará a conocer información intrascendente para ocultar lo realmente trascendente; respecto al "Rey del Cash" la estrategia es diferente, pues los mensajeros de AMLO se encargarán de manejar todo como un "chisme" sin sustento, siendo que el libro es solo una crónica.Esta es la opinión de Pedro Ferriz de Con.

'Hackeo a la Sedena es un problema muy grave'. ¿Cómo solicitar la factura electrónica o CFDI a un establecimiento comercial?. 'Hackeo de Guacamaya Leaks extrajo 6TB en datos de la Sedena'.

This week's highlights

Western Digital has unveiled its new 22TB CMR and 26TB UltraSMR hard disk drives (HDDs) which are now being tested by select hyperscale cloud . Western Digital has unveiled its new 22TB CMR and 26TB UltraSMR hard disk drives (HDDs) which are now being tested by select hyperscale cloud customers. The reason the storage giant has been able to significantly expand the capacity of HDDs over the years is due to its ever expanding technology portfolio which includes its unique OptiNAND technology, energy-assisted PMR (ePMR), triple-stage actuator (TSA), HelioSeal and now UltraSMR. Western Digital's new ePMR drives leverage the company's OptiNAND technology to unlock higher levels of capacity, performance and data resiliency. For instance, its new 22TB CMR HDD incorporates OptiNAND to deliver areal density on a 2.2TB/platter HelioSeal platform with ten disks. While the average consumer likely doesn't have a need for such a high capacity drive, cloud computing providers and other tech giants can use Western Digital's HDDs to store more data in less space which could help bring down the cost of cloud storage services for end users. UltraSMR By combining OptiNAND with proprietary firmware that leverages HDD system-level hardware advancements, Western Digital's new UltraSMR technology introduces large block encoding with an advanced error correction algorithm that increases track-per-inch (TPI) to enable higher capacity HDDs. The first HDD to use this new technology is the company's new 26TB Ultrastar DC HC670 UltraSMR HDD that features 2.6TB per platter and offers 18 percent more storage capacity. However, as cloud service providers are increasingly adding SMR to their datacenter roadmaps, the drive's 26TB capacity could serve as a tipping point to accelerate adoption. Read More > Samsung, Western Digital join forces on next-gen SSD technology > Western Digital plots to squeeze the tape market with massive archive HDDs > Western Digital customers urged to update to latest version of My Cloud OS EVP and GM of Western Digital's HDD Business Unit, Ashley Gorakhpurwalla provided further insight on the company's HDD technology portfolio in a press release, saying: “As a longstanding partner of the industry's leading cloud providers, we understand their unique requirements in building next-generation cloud infrastructure and invested in several HDD innovations we developed alongside our areal density technology. Our intent with taking this development strategy was not only to address the capacity demands of the world's largest cloud titans but to deliver on a roadmap that would also support the evolving economics of their data centers for decades to come. With ePMR, OptiNAND and now UltraSMR as the foundation of Western Digital's HDD roadmap, our cloud customers can continue rapidly scaling their business by taking advantage of our innovations to lower their storage TCO.” The 22TB Ultrastar DC HC570 HDD will soon begin volume shipments to the channel while the 26TB Ultrastar DC HC670 UltraSMR HDD is set to begin shipping to select customers this summer.

+++BLITZLICHT+++ +Neues Format+ +++ Meine Erfahrungen mit amazon.fr, vom anderen Stern! +++Ich hatte Euch mitgeteilt, dass ich mich in meiner Babypause befinde und daher aktuell keinen Rhythmus für neue Blogs und PodCasts, mit gewohnter Verlässlichkeit, benennen oder auch nur annähernd halten kann. Und so kam mir die Idee für das +++BLITZLICHT+++: Ein PodCast ohne Schnörkel, schnell auf den Punkt und in wenigen Minuten mit allen Informationen, die ihr braucht. Und hier kommt das nächste +++BLITZLICHT+++: Meine neueste Erfahrung mit amazon - allerdings Frankreich. Und was soll ich sagen: vom anderen Stern, unfassbar! "Aufgeschreckt" durch einen Hammerpreis für eine SSD eines namhaften Herstellers mit einer Kapazität, die meine Hemmschwelle für einen Spontankauf auf Null senkte, bestellte ich über amazon Frankreich. Das ist nicht meine erste Untreue amazon Deutschland gegenüber, ich besitze Konten bei amazon quer durch ganz Europa, auch noch in UK. Dass ich nur mit Hilfe des Google Chrome Browsers und dem mittlerweile wirklich guten Übersetzungsmodul in der Lage war, meine Bestellung abzuschicken, muss ich wohl nicht extra erwähnen. Dies hatte mir bei Bestellungen in Spanien und Portugal auch immer treue Dienste geleistet. Die Lieferung der Platte hat drei verdammt lange Tage gedauert. Und als ich endlich die Verpackung öffnen und die Platte an den Rechner packen konnte - hatte das Teil 1,6TB. Und aus. Problem: da fehlten 2,4TB! Ein bisschen technische Nachtschicht später und auch die Installation des von Samsung empfohlenen hauseigenen Tool "Magician", welches keinerlei Werte der Platte lesen konnte und auch die Seriennummer mit "unknown device" quittierte, veranlasste mich, Kontakt zu amazon.fr zu suchen. Und die Odyssee begann: Eine Rückfrage, ob die Platte defekt oder Fake sei, in einem einfachen Englisch, wurde mit einer Antwort, dass nur französische Nachrichten bearbeitet werden können, quittiert. Allerdings, und hier war ich mir bei der Formulierung nicht sicher, wurde auf eine "future e-mail english@amazon.fr" verwiesen. Also, Mail copy-paste-senden. Fehlermeldung, die email existiert nicht. Die Franzosen meinen es echt erst! Über den Artikel einen Chat eröffnen. Jetzt treibe ich es auf die Spitze: ich habe Chrome und kann Euch verstehen. Mal sehen, was ihr könnt, wenn die Nachricht nun auf Deutsch kommt. Es kam wie es kommen musste: nur französisch. Chat beendet. Danke, Antoine! Mir egal, zum Artikel, Rücksendung. Und nun, die nächste Ernüchterung. Eine amazon.es-Bestellung, die nicht meine Erwartungen erfüllt hat, habe ich ebenfalls per "Rücksendung" mit Etikette versehen - und an, ja wirklich, amazon Deutschland geschickt. Auch mit einer UK-Rücksendung lief es so. Und dann: amazon.fr: will Rücksendung an sich selbst, auch wenn das Lager, das meine Sendung in Empfang nehmen sollte, in der Slowakei liegt. Immerhin: die Rücksendung musste ich zahlen, allerdings erstattet amazon.fr pauschal 7,99€ Portokosten. Stand da zumindest, bisher habe ich davon nichts mehr gesehen und gehört. Erstattet habe ich diese auch NICHT bekommen! So wenig Verlass bin ich auch amazon gar nicht gewöhnt... auf jeden Fall wird Frankreich künftig keine Bestellung oder auch nur einen Cent Gewinn mehr mit mir machen!!! Ein kleiner Vergleich zwischen DHL und Hermes ergab schnell, dass Hermes das Paket transportiert. Da ich mich komplett veräppelt fühlte, suchte ich nach einer email von Amazon EU. So einfach lass ich mich nicht abbügeln. Parallel noch eine Mail an .fr geschickt. Und ab ins Bett. Am nächsten Morgen ging das Paket zu Hermes - und als ich aus dem Shop trete, erhalte ich eine englisch-sprachige email von amazon.fr. Ich war baff. Aber der Inhalt machte mich noch mehr baff: Das Etikett, welches ich gestern schon geschickt bekommen hatte, wäre wohl ein Frei-Etikett, wohl komplett bezahlt... aber, wenn ich den Aufdruck richtig verstehe, nur innerhalb Frankreichs. Hermes hat nun bis zum 15.09. gebraucht, um die Platte nun in die Slowakei zu bringen, nun warte ich nur noch auf die Bestätigung, dass die Zahlung zu mir zurück kommt. Das kann wohl auch noch ein wenig dauern... aber, in der Zeit, die ich gebraucht habe, um dem Blog und PodCast fertig zu bekommen, war die Kohle dann auch endlich da. Keine Rückmeldung, ob die Platte nun ging oder nicht. Nun denn - Klartext! Reden wir mal Klartext: +++ + +++: Der Preis war genial, dank Google Chrome als Browser mit integrierter Übersetzung war schnell bestellt, die Lieferung war für grenzüberschreitenden Warenverkehr flott bei mir. Aber... +++ - +++: Als amazon-Tochter nur französisch zu fordern, ist schon mehr als dreist. Erst recht, mit dem Verweis, auf eine KÜNFTIGE email-Adresse. Es sollte Pflicht sein, dass alle Seiten zumindest englisch als Zweitsprache akzeptieren müssen - es gibt genug kostenfreie Übersetzer im Netz! Warum ich zum Unterschied Spanien/UK nun Selbstzahler bin und es nicht lokal adressieren konnte bzw. mir die pauschale Erstattung der Versandkosten nicht erstattet wurde, geht mir tierisch auf den Sack. Ein Kontakt zu amazon EU wäre nett, das möchte ich gerne im Detail erörtern! Und, unter uns gesagt: Finger weg von amazon.fr, wenn ihr nicht französisch sprecht - es gibt genug amazon drum rum, die sich liebend gerne auch in englisch um uns zahlende Kunden kümmern und nicht Rücksendeversandkosten prellen müssen!

Its primary mission was simple yet highly challenging: prevent malaria from spreading across the nation. Armed with a budget of only $10 million and fewer than 400 employees, the agency’s early challenges included obtaining enough trucks, sprayers, and shovels necessary to wage war on mosquitoes.

Dr. Ziya Ma, vice president of Intel® Software and Services Group and director of Data Analytics Technologies, gives Chip Chat listeners a look at data center optimization along with a preview of advancements well underway. In their work with the broad industry, Dr. Ma and her team have found that taming the data deluge calls for IT data center managers to unify their big data analytics and AI workflows. As they’ve helped customers overcome the memory constraints involved in data caching, Apache Spark*, which supports the convergence of AI on big data, has proven to be a highly effective platform. Dr. Ma and her team have already provided the community a steady stream of source code contributions and optimizations for Spark. In this interview she reveals that more – and even more exciting work – is underway. Spark depends on memory to perform and scale. That means optimizing Spark for the revolutionary new Intel® Optane™ DC persistent memory offers performance improvement for the data center. In one example, Dr. Ma describes benchmark testing where Spark SQL performs eight times faster at a 2.6TB data scale using Intel Optane DC persistent memory than a comparable system using DRAM DIMMs. With Intel Optane DC persistent memory announced and broadly available in 2019, data centers have the chance to achieve workflow unification along with performance gains and system resilience starting now. For more information about Intel’s work in this space, go to software.intel.com/ai. For more about how Intel is driving advances in the ecosystem, visit intel.com/analytics. Performance results are based on Intel internal testing: 8X faster insights (8/2/2018) based on Apache Spark* SQL IO intensive queries for Analytics vs. DRAM+HDD at 2.6TB data scale; 9X read transactions and 11X users per system (5/29/2018) based on Apache* Cassandra-4.0 workload doing 100% reads vs. comparable server system with DRAM & NAND NVME Drives; 12.5X faster restart times (5/30/2018) based on running SAP HANA 2.0 SPS 03, and may not reflect all publicly available security updates.

6 metrics for zpool performance, 2FA with ssh on OpenBSD, ZFS maintaining file type information in dirs, everything old is new again, netcat demystified, and more. ##Headlines Six Metrics for Measuring ZFS Pool Performance Part 1 The layout of a ZFS storage pool has a significant impact on system performance under various workloads. Given the importance of picking the right configuration for your workload and the fact that making changes to an in-use ZFS pool is far from trivial, it is important for an administrator to understand the mechanics of pool performance when designing a storage system. To quantify pool performance, we will consider six primary metrics: Read I/O operations per second (IOPS) Write IOPS Streaming read speed Streaming write speed Storage space efficiency (usable capacity after parity versus total raw capacity) Fault tolerance (maximum number of drives that can fail before data loss) For the sake of comparison, we’ll use an example system with 12 drives, each one sized at 6TB, and say that each drive does 100MB/s streaming reads and writes and can do 250 read and write IOPS. We will visualize how the data is spread across the drives by writing 12 multi-colored blocks, shown below. The blocks are written to the pool starting with the brown block on the left (number one), and working our way to the pink block on the right (number 12). Note that when we calculate data rates and IOPS values for the example system, they are only approximations. Many other factors can impact pool access speeds for better (compression, caching) or worse (poor CPU performance, not enough memory). There is no single configuration that maximizes all six metrics. Like so many things in life, our objective is to find an appropriate balance of the metrics to match a target workload. For example, a cold-storage backup system will likely want a pool configuration that emphasizes usable storage space and fault tolerance over the other data-rate focused metrics. Let’s start with a quick review of ZFS storage pools before diving into specific configuration options. ZFS storage pools are comprised of one or more virtual devices, or vdevs. Each vdev is comprised of one or more storage providers, typically physical hard disks. All disk-level redundancy is configured at the vdev level. That is, the RAID layout is set on each vdev as opposed to on the storage pool. Data written to the storage pool is then striped across all the vdevs. Because pool data is striped across the vdevs, the loss of any one vdev means total pool failure. This is perhaps the single most important fact to keep in mind when designing a ZFS storage system. We will circle back to this point in the next post, but keep it in mind as we go through the vdev configuration options. Because storage pools are made up of one or more vdevs with the pool data striped over the top, we’ll take a look at pool configuration in terms of various vdev configurations. There are three basic vdev configurations: striping, mirroring, and RAIDZ (which itself has three different varieties). The first section will cover striped and mirrored vdevs in this post; the second post will cover RAIDZ and some example scenarios. A striped vdev is the simplest configuration. Each vdev consists of a single disk with no redundancy. When several of these single-disk, striped vdevs are combined into a single storage pool, the total usable storage space would be the sum of all the drives. When you write data to a pool made of striped vdevs, the data is broken into small chunks called “blocks” and distributed across all the disks in the pool. The blocks are written in “round-robin” sequence, meaning after all the disks receive one row of blocks, called a stripe, it loops back around and writes another stripe under the first. A striped pool has excellent performance and storage space efficiency, but absolutely zero fault tolerance. If even a single drive in the pool fails, the entire pool will fail and all data stored on that pool will be lost. The excellent performance of a striped pool comes from the fact that all of the disks can work independently for all read and write operations. If you have a bunch of small read or write operations (IOPS), each disk can work independently to fetch the next block. For streaming reads and writes, each disk can fetch the next block in line synchronized with its neighbors. For example, if a given disk is fetching block n, its neighbor to the left can be fetching block n-1, and its neighbor to the right can be fetching block n+1. Therefore, the speed of all read and write operations as well as the quantity of read and write operations (IOPS) on a striped pool will scale with the number of vdevs. Note here that I said the speeds and IOPS scale with the number of vdevs rather than the number of drives; there’s a reason for this and we’ll cover it in the next post when we discuss RAID-Z. Here’s a summary of the total pool performance (where N is the number of disks in the pool): N-wide striped: Read IOPS: N * Read IOPS of a single drive Write IOPS: N * Write IOPS of a single drive Streaming read speed: N * Streaming read speed of a single drive Streaming write speed: N * Streaming write speed of a single drive Storage space efficiency: 100% Fault tolerance: None! Let’s apply this to our example system, configured with a 12-wide striped pool: 12-wide striped: Read IOPS: 3000 Write IOPS: 3000 Streaming read speed: 1200 MB/s Streaming write speed: 1200 MB/s Storage space efficiency: 72 TB Fault tolerance: None! Below is a visual depiction of our 12 rainbow blocks written to this pool configuration: The blocks are simply striped across the 12 disks in the pool. The LBA column on the left stands for “Logical Block Address”. If we treat each disk as a column in an array, each LBA would be a row. It’s also easy to see that if any single disk fails, we would be missing a color in the rainbow and our data would be incomplete. While this configuration has fantastic read and write speeds and can handle a ton of IOPS, the data stored on the pool is very vulnerable. This configuration is not recommended unless you’re comfortable losing all of your pool’s data whenever any single drive fails. A mirrored vdev consists of two or more disks. A mirrored vdev stores an exact copy of all the data written to it on each one of its drives. Traditional RAID-1 mirrors usually only support two drive mirrors, but ZFS allows for more drives per mirror to increase redundancy and fault tolerance. All disks in a mirrored vdev have to fail for the vdev, and thus the whole pool, to fail. Total storage space will be equal to the size of a single drive in the vdev. If you’re using mismatched drive sizes in your mirrors, the total size will be that of the smallest drive in the mirror. Streaming read speeds and read IOPS on a mirrored vdev will be faster than write speeds and IOPS. When reading from a mirrored vdev, the drives can “divide and conquer” the operations, similar to what we saw above in the striped pool. This is because each drive in the mirror has an identical copy of the data. For write operations, all of the drives need to write a copy of the data, so the mirrored vdev will be limited to the streaming write speed and IOPS of a single disk. Here’s a summary: N-way mirror: Read IOPS: N * Read IOPS of a single drive Write IOPS: Write IOPS of a single drive Streaming read speed: N * Streaming read speed of a single drive Streaming write speed: Streaming write speed of a single drive Storage space efficiency: 50% for 2-way, 33% for 3-way, 25% for 4-way, etc. [(N-1)/N] Fault tolerance: 1 disk per vdev for 2-way, 2 for 3-way, 3 for 4-way, etc. [N-1] For our first example configuration, let’s do something ridiculous and create a 12-way mirror. ZFS supports this kind of thing, but your management probably will not. 1x 12-way mirror: Read IOPS: 3000 Write IOPS: 250 Streaming read speed: 1200 MB/s Streaming write speed: 100 MB/s Storage space efficiency: 8.3% (6 TB) Fault tolerance: 11 As we can clearly see from the diagram, every single disk in the vdev gets a full copy of our rainbow data. The chainlink icons between the disk labels in the column headers indicate the disks are part of a single vdev. We can lose up to 11 disks in this vdev and still have a complete rainbow. Of course, the data takes up far too much room on the pool, occupying a full 12 LBAs in the data array. Obviously, this is far from the best use of 12 drives. Let’s do something a little more practical and configure the pool with the ZFS equivalent of RAID-10. We’ll configure six 2-way mirror vdevs. ZFS will stripe the data across all 6 of the vdevs. We can use the work we did in the striped vdev section to determine how the pool as a whole will behave. Let’s first calculate the performance per vdev, then we can work on the full pool: 1x 2-way mirror: Read IOPS: 500 Write IOPS: 250 Streaming read speed: 200 MB/s Streaming write speed: 100 MB/s Storage space efficiency: 50% (6 TB) Fault tolerance: 1 Now we can pretend we have 6 drives with the performance statistics listed above and run them through our striped vdev performance calculator to get the total pool’s performance: 6x 2-way mirror: Read IOPS: 3000 Write IOPS: 1500 Streaming read speed: 3000 MB/s Streaming write speed: 1500 MB/s Storage space efficiency: 50% (36 TB) Fault tolerance: 1 per vdev, 6 total Again, we will examine the configuration from a visual perspective: Each vdev gets a block of data and ZFS writes that data to all of (or in this case, both of) the disks in the mirror. As long as we have at least one functional disk in each vdev, we can retrieve our rainbow. As before, the chain link icons denote the disks are part of a single vdev. This configuration emphasizes performance over raw capacity but doesn’t totally disregard fault tolerance as our striped pool did. It’s a very popular configuration for systems that need a lot of fast I/O. Let’s look at one more example configuration using four 3-way mirrors. We’ll skip the individual vdev performance calculation and go straight to the full pool: 4x 3-way mirror: Read IOPS: 3000 Write IOPS: 1000 Streaming read speed: 3000 MB/s Streaming write speed: 400 MB/s Storage space efficiency: 33% (24 TB) Fault tolerance: 2 per vdev, 8 total While we have sacrificed some write performance and capacity, the pool is now extremely fault tolerant. This configuration is probably not practical for most applications and it would make more sense to use lower fault tolerance and set up an offsite backup system. Striped and mirrored vdevs are fantastic for access speed performance, but they either leave you with no redundancy whatsoever or impose at least a 50% penalty on the total usable space of your pool. In the next post, we will cover RAIDZ, which lets you keep data redundancy without sacrificing as much storage space efficiency. We’ll also look at some example workload scenarios and decide which layout would be the best fit for each. ###2FA with ssh on OpenBSD Five years ago I wrote about using a yubikey on OpenBSD. The only problem with doing this is that there’s no validation server available on OpenBSD, so you need to use a different OTP slot for each machine. (You don’t want to risk a replay attack if someone succeeds in capturing an OTP on one machine, right?) Yubikey has two OTP slots per device, so you would need a yubikey for every two machines with which you’d like to use it. You could use a bastion—and use only one yubikey—but I don’t like the SPOF aspect of a bastion. YMMV. After I played with TOTP, I wanted to use them as a 2FA for ssh. At the time of writing, we can’t do that using only the tools in base. This article focuses on OpenBSD; if you use another operating system, here are two handy links. SEED CONFIGURATION The first thing we need to do is to install the software which will be used to verify the OTPs we submit. # pkgadd loginoath We need to create a secret - aka, the seed - that will be used to calculate the Time-based One-Time Passwords. We should make sure no one can read or change it. $ openssl rand -hex 20 > ~/.totp-key $ chmod 400 ~/.totp-key Now we have a hexadecimal key, but apps usually want a base32 secret. I initially wrote a small script to do the conversion. While writing this article, I took the opportunity to improve it. When I initially wrote this utility for my use, python-qrcode hadn’t yet been imported to the OpenBSD ports/packages system. It’s easy to install now, so let’s use it. Here’s the improved version. It will ask for the hex key and output the secret as a base32-encoded string, both with and without spacing so you can copy-paste it into your password manager or easily retype it. It will then ask for the information needed to generate a QR code. Adding our new OTP secret to any mobile app using the QR code will be super easy! SYSTEM CONFIGURATION We can now move to the configuration of the system to put our new TOTP to use. As you might guess, it’s going to be quite close to what we did with the yubikey. We need to tweak login.conf. Be careful and keep a root shell open at all times. The few times I broke my OpenBSD were because I messed with login.conf without showing enough care. SSHD CONFIGURATION Again, keeping a root shell around decreases the risk of losing access to the system and being locked outside. A good standard is to use PasswordAuthentication no and to use public key only. Except… have a guess what the P stands for in TOTP. Yes, congrats, you guessed it! We need to switch to PasswordAuthentication yes. However, if we made this change alone, sshd would then accept a public key OR a password (which are TOTP because of our login.conf). 2FA uses both at the same time. To inform sshd we intend to use both, we need to set AuthenticationMethods publickey,password. This way, the user trying to login will first need to perform the traditional publickey authentication. Once that’s done, ssh will prompt for a password and the user will need to submit a valid TOTP for the system. We could do this the other way around, but I think bots could try passwords, wasting resources. Evaluated in this order, failing to provide a public key leads to sshd immediately declining your attempt. IMPROVING SECURITY WITHOUT IMPACTING UX My phone has a long enough password that most of the time, I fail to type it correctly on the first try. Of course, if I had to unlock my phone, launch my TOTP app and use my keyboard to enter what I see on my phone’s screen, I would quickly disable 2FA. To find a balance, I have whitelisted certain IP addresses and users. If I connect from a particular IP address or as a specific user, I don’t want to go through 2FA. For some users, I might not even enable 2FA. To sum up, we covered how to create a seed, how to perform a hexadecimal to base32 conversion and how to create a QR code for mobile applications. We configured the login system with login.conf so that ssh authentication uses the TOTP login system, and we told sshd to ask for both the public key and the Time-based One-Time Password. Now you should be all set to use two-factor ssh authentication on OpenBSD! ##News Roundup How ZFS maintains file type information in directories As an aside in yesterday’s history of file type information being available in Unix directories, I mentioned that it was possible for a filesystem to support this even though its Unix didn’t. By supporting it, I mean that the filesystem maintains this information in its on disk format for directories, even though the rest of the kernel will never ask for it. This is what ZFS does. The easiest way to see that ZFS does this is to use zdb to dump a directory. I’m going to do this on an OmniOS machine, to make it more convincing, and it turns out that this has some interesting results. Since this is OmniOS, we don’t have the convenience of just naming a directory in zdb, so let’s find the root directory of a filesystem, starting from dnode 1 (as seen before). # zdb -dddd fs3-corestaff-01/h/281 1 Dataset [....] [...] microzap: 512 bytes, 4 entries [...] ROOT = 3 # zdb -dddd fs3-corestaff-01/h/281 3 Object lvl iblk dblk dsize lsize %full type 3 1 16K 1K 8K 1K 100.00 ZFS directory [...] microzap: 1024 bytes, 8 entries RESTORED = 4396504 (type: Directory) ckstst = 12017 (type: not specified) ckstst3 = 25069 (type: Directory) .demo-file = 5832188 (type: Regular File) .peergroup = 12590 (type: not specified) cks = 5 (type: not specified) cksimap1 = 5247832 (type: Directory) .diskuse = 12016 (type: not specified) ckstst2 = 12535 (type: not specified) This is actually an old filesystem (it dates from Solaris 10 and has been transferred around with ‘zfs send | zfs recv’ since then), but various home directories for real and test users have been created in it over time (you can probably guess which one is the oldest one). Sufficiently old directories and files have no file type information, but more recent ones have this information, including .demo-file, which I made just now so this would have an entry that was a regular file with type information. Once I dug into it, this turned out to be a change introduced (or activated) in ZFS filesystem version 2, which is described in ‘zfs upgrade -v’ as ‘enhanced directory entries’. As an actual change in (Open)Solaris, it dates from mid 2007, although I’m not sure what Solaris release it made it into. The upshot is that if you made your ZFS filesystem any time in the last decade, you’ll have this file type information in your directories. How ZFS stores this file type information is interesting and clever, especially when it comes to backwards compatibility. I’ll start by quoting the comment from zfs_znode.h: /* * The directory entry has the type (currently unused on * Solaris) in the top 4 bits, and the object number in * the low 48 bits. The "middle" 12 bits are unused. */ In yesterday’s entry I said that Unix directory entries need to store at least the filename and the inode number of the file. What ZFS is doing here is reusing the 64 bit field used for the ‘inode’ (the ZFS dnode number) to also store the file type, because it knows that object numbers have only a limited range. This also makes old directory entries compatible, by making type 0 (all 4 bits 0) mean ‘not specified’. Since old directory entries only stored the object number and the object number is 48 bits or less, the higher bits are guaranteed to be all zero. The reason this needed a new ZFS filesystem version is now clear. If you tried to read directory entries with file type information on a version of ZFS that didn’t know about them, the old version would likely see crazy (and non-existent) object numbers and nothing would work. In order to even read a ‘file type in directory entries’ filesystem, you need to know to only look at the low 48 bits of the object number field in directory entries. ###Everything old is new again Just because KDE4-era software has been deprecated by the KDE-FreeBSD team in the official ports-repository, doesn’t mean we don’t care for it while we still need to. KDE4 was released on January 11th, 2008 — I still have the T-shirt — which was a very different C++ world than what we now live in. Much of the code pre-dates the availability of C11 — certainly the availability of compilers with C11 support. The language has changed a great deal in those ten years since the original release. The platforms we run KDE code on have, too — FreeBSD 12 is a long way from the FreeBSD 6 or 7 that were current at release (although at the time, I was more into OpenSolaris). In particular, since then the FreeBSD world has switched over to Clang, and FreeBSD current is experimenting with Clang 7. So we’re seeing KDE4-era code being built, and running, on FreeBSD 12 with Clang 7. That’s a platform with a very different idea of what constitutes correct code, than what the code was originally written for. (Not quite as big a difference as Helio’s KDE1 efforts, though) So, while we’re counting down to removing KDE4 from the FreeBSD ports tree, we’re also going through and fixing it to work with Clang 7, which defaults to a newer C++ standard and which is quite picky about some things. Some time in the distant past, when pointers were integers and NULL was zero, there was some confusion about booleans. So there’s lots of code that does list.contains(element) > 0 … this must have been a trick before booleans were a supported type in all our compilers. In any case it breaks with Clang 7, since contains() returns a QBool which converts to a nullptr (when false) which isn’t comparable to the integer 0. Suffice to say I’ve spent more time reading KDE4-era code this month, than in the past two years. However, work is proceeding apace, so if you really really want to, you can still get your old-school kicks on a new platform. Because we care about packaging things right, even when we want to get rid of it. ###OpenBSD netcat demystified Owing to its versatile functionalities, netcat earns the reputation as “TCP/IP Swiss army knife”. For example, you can create a simple chat app using netcat: (1) Open a terminal and input following command: # nc -l 3003 This means a netcat process will listen on 3003 port in this machine (the IP address of current machine is 192.168.35.176). (2) Connect aforemontioned netcat process in another machine, and send a greeting: # nc 192.168.35.176 3003 hello Then in the first machine’s terminal, you will see the “hello” text: # nc -l 3003 hello A primitive chatroom is built successfully. Very cool! Isn’t it? I think many people can’t wait to explore more features of netcatnow. If you are among them, congratulations! This tutorial may be the correct place for you. In the following parts, I will delve into OpenBSD’s netcatcode to give a detailed anatomy of it. The reason of picking OpenBSD’s netcat rather than others’ is because its code repository is small (~2000 lines of code) and neat. Furthermore, I also hope this little book can assist you learn more socket programming knowledge not just grasping usage of netcat. We’re all set.

We risked it for the biscuit (and gravy)! After stuffing our faces and sipping on mimosas, Alisha and Lara talk lots about drugs, and the local music/entertainment scene with special guest Kendra McKay! Kendra is a local business owner, musician, artist and all-around badass being. She also shares her story of a 3-month legal battle with an old ex, after calling out his abusive behavior during their relationship (and towards other women). For the best ever biscuits and sausage gravy you'll need: -6TB butter-2C flour-1TB sugar-1/4tsp baking soda-1TB baking powder-1tsp salt-1C buttermilk -1lb breakfast sausage-1/2C flour-3 or 4C whole milk (we used buttermilk and it was AMAZING)-1/2tsp salt-2tsp pepper Pre-heat your oven to 450 degrees. Cut the butter into small cubes (this works best if the butter is super duper chilled; we didn't have a pastry cutter and it was fine). Sift the dry ingredients together. Then add your cut up butter, it should be coarse and crumbly. Make a well in the middle of your bowl and add the buttermilk. Stir to combine until the dough is sticky/tacky. At this point you can roll out the dough and fold it over itself 6 times. We just freeformed the biscuits, because that's how we roll. Bake for 12-15 minutes until browned. While the biscuits are baking, make dat gravy, BABY! Brown your sausage in a large skillet on medium-high heat until there's no more pink. Add the flour and stir it up so it gets soaked up by the sausage. Pour in the milk whilst stirring constantly. Cook the gravy 10-12 minutes or until thickened. Season with salt and pepper to taste. Drown your biscuits in this gravy and prepare to reach utter and true bliss.

If you have questions, please share them below.

Hoy nos entretenemos con preguntas muy interesantes donde veremos una de las opciones que más valoro, los objetos inteligentes de Photoshop. Una herramienta básica si queremos aprovechar el máximo de calidad de nuestras imágenes, y que trataremos más en profundidad en el podcast. Ya está aquí la Navidad y con ella un ejército de Umba Lumbas que se unieron a Carrete tras el último podcast de BlackFriday, le damos la bienvenida a estos aventureros a nuestra fábrica de fotógrafos. Quería comenzar el podcast agradeciendo a todos y cada uno colaboración en este año, en especial a los grupos de Telegram, ya que siempre están ahí animando y sumándose a todas las locuras que se me ocurren.  Respondemos a la pregunta que lancé en el último podcast sobre Amazon Ilimitado, gracias a vuestras respuestas pude comprobar que Amazon ha actualizado su aplicación y funciona a la perfección, ¡parece que los chicos de Amazon escuchan este podcast!, por la parte que me toca sólo puedo agradecérselo, ya tengo mis 6TB subidos a la nube. ¡Santa paciencia!. Os he añadido una nueva funcionalidad, a partir de hoy podréis mandar vuestros audios a través de este enlace que también podréis encontrar en la zona de contacto. Ya podéis comentar, compartir, criticar, sugerir o dar vuestra opinión sobre lo que queráis, iremos publicando los audios en nuestro podcast, así que os animo a participar y a hacer vuestro también el podcast. Aprovechamos para anunciar a la tercera ganadora de una licencia Photopills, la última en recibir esta maravillosa aplicación, muchas gracias al equipo por las licencias que han sido repartidas entre los oyentes del podcast y muchas felicidades a Mary Paz (@Lolipey) en Twitter, ya que ha sido la afortunada. Comenzaremos el año con nuevos cursos, un año muy interesante donde se incorporarán nuevos profesores a nuestra escuela. Por mi parte impartiré el curso de Máscaras de Luminosidad y Cómo se Hizo, dos cursos muy interesantes donde empezaremos a ver técnicas más avanzadas y retoques fotográficos de principio a fin, seguro que os va a encantar, no me cabe duda. Jose Manuel Gallego Reina se encargará de otro de los cursos: Mantenimiento y Arreglo de Cámaras Reflex, dónde compartirá con nosotros su experiencia como técnico para enseñarnos aquellas cosas que podremos solventar por nuestra cuenta sin necesidad de acudir a un servicio técnico. Por otra parte Jesús Cabanillas desde Salamanca nos traerá un curso de Fotografía Analógica, también muy demandado por la comunidad. Comenzamos con las preguntas que ocuparán el podcast de hoy. La primera pregunta nos la realiza Jose Manuel García a razón de la última lección del curso de Edición y Trucos de Photoshop: Hola marco una pregunta ¿el objeto inteligente en photoshop trabaja más o menos como Lightroom com el raw que no modifica la foto, sino que guarda los ajustes? Los objetos inteligentes de Photoshop funcionan de forma parecida a un RAW, es un archivo contenedor que guarda información, ajustes, filtros, etc. Para abrir un RAW como objeto inteligente es tan fácil como pulsar la tecla ALT cuando estemos revelando en Camera RAW y veremos que la opción: Abrir Imagen, cambia por Abrir Objeto. De esta forma nos abrirá la imagen como un objeto inteligente de la cual podremos empezar a trabajar de forma muy distinta a como se trabaja con una imagen. Más adelante veremos como trabajar con objetos inteligentes, ya que esta opción nos abre un abanico de posibilidades a la hora del retoque bastantes potentes que deberemos conocer si queremos profundizar en la calidad de nuestro flujo de trabajo. Os dejo la fotografía de la que hablo en el podcast sobre la Capilla Sixtina, una imagen bastante curiosa e interesante que pronto estará disponible en el curso de Cómo se Hizo, donde trabajamos con ella a través de objetos inteligentes.     Segunda pregunta de Fernando García que nos pregunta sobre los derechos de autor, un tema muy interesante y controvertido que ya tratamos en otro podcast anterior. Estimado Marco Antonio Me llamo Fernando, soy un aficionadillo apasionado de la fotografía. Lo primero agradecerte tu trabajo en carretedigital y los podcats, estoy aprendiendo mucho con ellos, te estoy muy muy agradecido por tu gran trabajo. Me gustaría hacerte una consulta sobre un caso que me está pasando estos días: Resulta que participé en un concurso de fotografía en verano de un periódico importante de Guipúzcoa. Mi fotografía no ganó premio ninguno, pero resulta que me entero por casualidad que están usando mi fotografía como foto de cabecera en su Facebook. Es más, están utilizando la foto haciendo banners de publicidad con ella dentro Facebook. (No he mirado en otras redes sociales) Lo que ellos indican en las bases del concurso, es que “Se reservan el derecho de uso de las imágenes participantes para acciones promocionales propias”. No se dignaron a poner el nombre del autor en la foto hasta que me puse en contacto con ellos por el chat del Facebook, lo pusieron a los 5 minutos (ahí se portaron bien). Les comenté lo del derecho moral que indicas en tu podcast , me dieron la razón. En los banner de publicidad no indican el nombre del autor, ¿pueden hacer eso? Están usando la imagen para acciones promocionales propias, eso es correcto “creo”. Mi pregunta es la siguiente: Si subes algo a facebook, le estás dando derecho a facebook para que utilicen tu imagen para lo que quieran “creo”. Ya hay una empresa que está usando mi foto sin mi permiso porque se lo ha dado el “periódico”. ¿El periódico tiene derecho a hacer eso? No sé si me explico… La verdad que hay que leerse muy bien las bases. Me molestó mucho que no indicaran el nombre del autor a la primera. La imagen tiene como 1700 megustas, la han compartido 640 veces etc… y sigue como cabecera de su Facebook desde hace unos 20 días. ¿Legalmente correcto pero éticamente incorrecto? La verdad que me está viniendo bien la experiencia para aprender un poco de derechos de autor.Muchísimas gracias por tu tiempo Y por último y no menos importante, otra pregunta de Alain. Hola: Escribo porque hace poco que me empece a interesar por la fotografía y descubrí la página, aun me estoy poniendo al día con el podcast. Me han dejado una cámara Olympus e500 y te quería consultar una duda. Le voy cogiendo el truco a la Camara, pero al sacar fotos en interiores o en condiciones de no demasiada luz la cámara pide siempre un tiempo de obturación enorme. Es normal que dentro de casa sea muy difícil sacar una foto bien sin usar el flash o se debe a la antigüedad de la cámara? La cámara tendrá  8 o 9 años ya y pensé que el problema podría ser ese. Es que me siento muy frustrado cuando intento usarla en casa y veo que con el móvil si puedo sacar la foto y sin embargo con la cámara no porque me pide medio segundo de tiempo de obturación. Gracias por el podcast, los que no sabemos nada aprendemos mucho con el. También dejamos el podcast donde hablamos de la fotografía móvil, muy interesante.

CEDIA 2016 Each year CEDIA (Custom Electronic Design and Installation Association) holds an event where the industry gathers to show off their wares. It is akin to a mini-CES, but also for many of us represents a best of CES of sorts. When we've been to attend the show, we tend to enjoy it more than CES. It takes the parts of CES that we are interested in and compresses it down to a more manageable show. We didn't go this year but that won't stop us from talking about some of the products we think are interesting. This year the show was from September 13-17 in Dallas, TX. High-Def Digest: Top Six Highlights from CEDIA 2016 Sony UBP-X1000ES Sony has their first entry into the world of Ultra HD Blu-ray players. But there is catch, this ES model is only for integrators. Even so, it's a pretty clear view of what we can expect when the consumer version is finally announced. The Ultra HD Blu-ray was just one part of Sony's booth, but, at least for this event, Sony made it clear that HDR is an important focus in the current line, both in the Master Drive TVs and in projectors like the VPL-VW5000ES. KEF Blade Two With good reason, most of the serious audio demonstrations at CEDIA 2016 required at the least a demonstration enclosure, and at the most indulgent, a suite. The KEF Blade Two, however, stood in a pair right in the open middle of the KEF booth. That stereo image, produced by two Blade Twos running off of a Hegel H360 (and networked FLAC tracks), was so poised in the din of the convention center and the booth, I had trouble even thinking of places in homes and well, luxury hotels, that wouldn't be made better with a pair of the large but not intimidating speakers. Naturally, the rest of the booth, which housed gems like the KEF Ci Series, had that kid in a toy store feel. LG Signature OLED77G6P Not only is the OLED65G6P basically breathe-taking in that undeniable beauty time of way, but the undeniability applies to both the picture and form. And here, in mid-to-late 2016, what could LG do to top this show-stopper? That would be to debut a 77" version. This new model exudes the same lines, but in a greater size more apropos of in-home cinema. The reason I say that now is a good time to make the trek to see the Signature line is that the 77" (and its even bigger $20k price tag) is already ready at certain showrooms in the States. Modulus Media Hub The Modulus Media Hub promises a lot, including DVD and Blu-ray archiving, a wealth of streaming service support, a base 6TB capacity with external expansion, 4K support, remote media access, and a DVR capability that applies to everything (including streaming). But what struck me is that the Modulus has the hardware (apparently) to also host Ultra HD Blu-rays. Unfortunately, that particular capability is not a certainty. CEDIA: Seven Trends We've Seen at CEDIA 2016 (we will discuss 4 of them…) Voice is the New Mouse and/or Swipe Given the Friday Keynote and a number of CEDIA Talks, it was easy to predict VUI would be a pretty hot topic. But as more and more manufacturers in the CEDIA channel explore integrating some manner of voice control into their products – from whole-home audio to security systems – it's pretty clear that the entire industry's betting on the next step in computer interaction. Everybody's at the Table OK, maybe it's not quite time to dump the term “DIY” yet – but seeing products that are pitched directly to the consumer side-by-side with pro models is an incredibly interesting trend. Back to VUI – yeah, you can buy your own interface device, but that same technology is going into gear used in big integration projects. It seems that there's a parallel development at work — and a realization that as a broader spectrum of the populace gets really interested in this stuff, that rising tide will lift every boat. The Home Needs an IT Pro We've heard more stats about the Internet of Things than devices that are actually on the Internet of Things. Alright, that's a total exaggeration, but still – the challenges that the IoT is presenting when it comes to interoperability, security, and network troubleshooting will translate into ever larger opportunities for that less-than-artful acronym “RMR.” Speakers Should Either Be Gorgeous or Invisible Not a new trend per se, but the difference between the “buried in the sheetrock and still sounds amazing” and the speaker-as-sculpture philosophy really struck your humble scribe over the last few days. Both the aural effects of the invisible speakers and the visual impact from those who treat this gear as high-end design has been jaw-dropping. CE Pro: Editor's Pick: 12 Great New Products from CEDIA 2016 Stewart Filmscreen Phantom HALR Screen The top manufacturer in CE Pro's Brand Analysis in the screen category reinforced its standing with its Phantom HALR black screen. Available in sizes up to 40 x 90 feet, with specification options for rollable installations, and acoustically transparent applications, dealers can use it for residential and commercial jobs. The Phantom produced stunning images on the show floor and its brightly lit aisles. Running a demo with Digital Projection, Stewart says it measured a contrast ratio on the floor of 90:1 and the black-and-white video with the screen looked incredible with no hint of color shift. Meyer Sound Demo Over in the world of pro sound, Meyer Sound is a benchmark brand of speakers . About 10 years ago the company migrated into the movie post-production category branching out from its roots as a sound reinforcement company and quickly established itself as a go-to brand. Now it's coming into the residential market and it's bringing the same level of quality. Working with the Dallas-based dealer Elliston Systems, Meyer partnered with Barco, Vutec and Keith Yates Design to deliver one of the best demos ever produced at a trade show. Barco Thor Projector Another benchmark manufacturer coming from the pro market and into the residential field is Barco. Showing its state-of-the-art Thor 6P laser 4K projector, you could say Barco's Thor dropped the hammer on the competition. Showing a mix of content that included 4K HDR, the Thor provided one of the best demos I've seen at a CEDIA show. Barco even realized the importance of audio with home theater and didn't cut corners with the audio portion of its demo. Autonomic MMS-1e Whole-House Music Player Streamlining the size and installation process for dealers, Autonomic introduced MMS-1e Whole-House Music Player and M-120e 4-zone amplifier. These products provide dealers with all of the familiar functions that have made Autonomic a top provider of whole-house audio systems with the simplified connectivity of its eAudioCast audio-over-Ethernet technology. The MMS-1e provides a choice of audio output formats, Wi-Fi support, control system integration, plus the company's great user interface. The MMS-1e carries an MSRP of just $995. Origin Acoustics B&O Partnership Jeremy Burkhardt has demonstrated once again that he is an industry leader. Combining his company's engineering prowess with the famous industrial design of Bang & Olufsen (B&O), Origin announced a partnership with B&O in which jointly developed products will be available in 700 B&O store locations. Select B&O products will be available to Origin dealers. Unlike the trend to hide architectural speakers, the point of the Origin and B&O collaboration is to show these speakers, which feature B&O's famous industrial design. Digital Projection (DP) e-Vision 4K Laser DP annually makes my best product lists for good reason: the company designs great performing products. The e-Vision 4K Laser is designed to balance performance and cost considerations and it meets all of its objectives. The 8,000-lumen projector provides a lamp life of 20,000 hours and 4K compatibility through the new TI 0.66 DLP chip for a reasonable price of $19,999. I was impressed with the e-Vision 4K Laser's bright and punchy, noise-free highly detailed UltraHD images during the company's demo. Epson LS10500 Projector Epson showcased its LS10500 in a great demo. The new LS10500 provides a lamp life of 30,000 hours, HDR compatibility and 1,500 lumens of color brightness and 1,500 lumens of white brightness. While not a true 4K projector in that it is not a native 4K solution, the LS10500 still delivers a vivid, detailed image that is impossible to match at its price point of $7,999 while accepting Ultra HD signals. Phase Technology CI-130 In-Wall Loudspeaker Showing again that it engineers some of the industry's best “secrets,” the company was showing its new IW-210 in-wall sub and its CI-130 in-wall speakers. This hybrid sealed-box design features a unique design that employs foam holes to allow the speaker to defeat some of the common limitations of architectural products. The CI-130 with the IW-210 produced a huge soundstage that was dynamic and seamless in its sonic integration. Sony UBP-X1000ES Ultra Blu-ray Disc Player It would be an understatement to say that Sony crushed CEDIA 2016. The popular electronics company just about stole the show with the introduction of its new Z-series Ultra HD televisions, new ES A/V receivers, and its UBP-X1000ES UltraHD Blu-ray disc player. Checking in at an approximate price point of $900, it's safe to say the Ultra HD Blu-ray disc category is now validated. Arguably the most anticipated product at the entire show, it offers HDR compatibility, as well as the ability to play DVD-Audio, DVD video, CDs, SACDs, Blu-ray discs, 3D Blu-ray discs and BD-ROMs. It also offers streaming services such as Amazon and YouTube as well as Dolby Atmos compatibility. RBH Sound SV 6500 Signature Reference Speaker RBH's lead engineer Shane Rich quietly designs some of the best speakers on the market. Showing his design talent Rich redesigned its Signature Reference speaker to include Air Motion Tweeters (AMT). As always RBH delivers some of CEDIA's best demos and CEDIA 2016 didn't disappoint with a surround clip from Eric Clapton's “Crossroads” shows and the musicianship of Derek Trucks, Warren Haynes and Susan Tedeschi. Highlighting its surround system was the Signature Reference SV-6500 R floorstanding speaker. CE Pro: What Dealers Say about CEDIA 2016 Bose Lifestyle 650 Bose's new Lifestyle 650 home audio system surprised a lot of integrators at CEDIA. One of them, who didn't want to be named because he's a big Sonos dealer, said, "I couldn't get over how much they've improved the platform. ... The fit, the finish, the feel, they look serious." He says the new little speakers deliver "spacious sound" and strong bass and, of all the compliments, "even the [SoundTouch] app looks respectable." Sony Z-Series displays Check social media. Seems everyone took a picture in front of this 100-inch Z-Series display from Sony. One dealer says "It's as good as it gets." It seemed most dealers were impressed with Sony's new Z-Series (Z9D) displays. At the booth it was noted that the 100-incher was only $60,000 – or half the price of Vizio's 120-inch TV. A dealer on RemoteCentral wonders: “The reps are claiming it's on par (or better than) the OLED. Your thoughts?” Integrator Mike Bruemmer of Cincinnati's Mt. Lookout Television and Electronics, agrees with the reps: “Sony Z9D was outstanding. Much better brightness than the OLED. We looked at the Z9 and ran to go look at the G6 [LG OLED]. Z9 is better.” Sony thrived on the 4K projector front as well. Crestron Crestron did not have an official presence at CEDIA this year, but the company's home-automation products appeared at several booths including Amazon Alexa and Sonos. Of all the new control systems integrating with Sonos, Crestron is the only one that embeds the entire Sonos interface in the automation UI. A Crestron dealer noted, “I saw the Crestron demo with Sonos. There is still some work to go. But one has to start somewhere. They have the link right to the Sonos app from the Crestron panel. Which is obviously a compromise at this point having to flip apps. At this point I would still suggest an Autonomic when doing Crestron systems.” Residential Systems: Real Audio Video VR: My CEDIA 2016 Game Changer REAL Audio Video is a top design and integration firm that has been doing ultra-high-end installs for more than 18 years. REAL partnered with another Utah based company, Fractal Mob, to create its new Private Cinema previsualization software, which was demonstrated at CEDIA for the first time. This previs software is not only incredibly innovative, but also potentially game changing in its use of virtual reality for aiding in the pre-sale and design of high end theaters. The two firms worked closely together on the project with REAL acting as technical consultants and providing Fractal with the floorplans, elevations, and reference photos to recreate the room in VR. By using virtual reality, REAL wants to let customers “walk through” their new theater space “before a single nail is driven.” For the demo, Fractal Mob took 4K VR scans of one of REAL's actual, already constructed theater designs. As the firm didn't have access to the actual room, they had to build everything from scratch—speakers, chairs, projector, room, textures, etc.—as if it didn't exist in real life, or exactly as it would be as if someone was previsualizing a room that had yet to be built. After the modeling is complete, the software lets you walk around and explore every inch of the room. The resulting image quality is nearly photo realistic, and in fact is limited by the current hardware limitations in VR rendering and will only improve as computing hardware catches up. Once inside the virtual space, you can walk up to walls and see the micro detail and texture in the fabric and the grain of the wood and quality of the millwork. Sconces gently bathe the sidewalls in light, the intensity and brightness changing as you walk up to them. Look back into the projector room and you see lens flare that changes based on the projected image and where you're standing in the room. There are even micro dust particles floating through the air in the light path of the projector. Kneel down and examine the carpet. Sit in different points in the room and see exactly how big—or small—your intended screen size looks. No more will the question, “Will 120 inches be too big from this seating position?” be a theoretical one. Now you can sit the client in the front row, the middle row, the back row and let them see exactly how big the screen will look at all seating locations. Same with seating. How will four seats look in a row? Put yourself in the space and see exactly how wide the pathways are. Or if the first row is low enough to not have sightline issues. Even more amazing—and educational—the audio tracks your position in the room, letting you move in and out of room modes so a customer can experience exactly what is happening with the audio and why the need for multiple subs and room correction—my friend Adam's specialty—is so crucial. While the VR demo video is playing, the audio also tracks as you turn your head as you turn from side to side, moving the stereo image position. Amazing.

In episode 20: Steve & Paul are back from their European tour after travelling in style. There was just time for quick visits to both BSC and BVE shows in London before walking backwards past Steve's house on an ITV crime special. The results from the 2015 Extrashot Cameraman's Survey are now in and we reveal what piece of kit most people are going to buy this year.  But, have our rates actually gone up enough to afford it? With the usual news, rants and dilemmas…. and the realisation that shooting 6TB of data in one day is probably too much… it's a packed episode.

This week on BSDNow, we will be talking shop with Josh Paetzel of FreeNAS fame, hearing about his best do's and do-nots of using ZFS in production. Also, a quick iX Systems Mission Complete (https://www.ixsystems.com/missioncomplete/) Submit your story of how you accomplished a mission with FreeBSD, FreeNAS, or iXsystems hardware, and you could win monthly prizes, and have your story featured in the FreeBSD Journal! *** FreeNAS Logo Design Contest (https://www.ixsystems.com/freenas-logo-contest/) Rules and Requirements (https://forums.freenas.org/index.php?threads/freenas-logo-design-contest.39968/) For those of you curious about Kris' new lighting here are the links to what he is using. Softbox Light Diffuser (http://smile.amazon.com/gp/product/B00OTG6474?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00&pldnSite=1) Full Spectrum 5500K CFL Bulb (http://smile.amazon.com/gp/product/B00198U6U6?psc=1&redirect=true&ref_=oh_aui_detailpage_o06_s00) *** This episode was brought to you by Headlines A Brief look back at 2015 (http://fossforce.com/2015/12/bsd-brief-look-back-2015/) As we start the show this week, we begin with a brief look back at BSD in 2015, brought to us by Larry at FOSS force. Aside from his issue with tap-to-click on the touchpad, his PC-BSD experience has been pretty good. (Larry, if you hear this, jump on #pcbsd on FreeNode and we will lend a hand) He mentions that this really isn't his first time running BSD, apparently back in ye-olden days he got NetBSD up and running on a PowerBook G3, until an update brought that experience to abrupt ending. He gives a shout-out to the FreeBSD Foundation as being a great go-to source for wrapup on the previous year in FreeBSD land, while also mentioning the great 4.4 release of DragonFly, and some of the variants, such as RetroBSD and LiteBSD He leaves us with a tease for 2016 that work is ongoing on Twitter to port over Mopidy, a python based extensible music server *** A look forward at BSD events throughout 2016 (http://www.bsdevents.org/scheduler/) After a quick look back at 2015, now its time to start planning your 2016 schedule. The BSDEvents site has a calendar of all the upcoming conferences / shows where BSD will have a presence this year. There are quite a few items on the agenda, including non BSD specific conferences, such as SCALE / Fosdem and more. Take a look and see, you may be able to find something close your location where you can come hang out with other BSD developers. (or better yet), if a linux conference is coming to your town, think about submitting a BSD talk! Additionally, if getting BSD Certification is something on your 2016 resolutions, you can often take the test at one of these shows, avoiding the need to travel to a testing center. *** The 'Hidden' Cost of Using ZFS for Your Home NAS (http://louwrentius.com/the-hidden-cost-of-using-zfs-for-your-home-nas.html) An article was recently posted that seems to be trying to dissuade people from using ZFS for their home NAS It points out what experienced users already know, but many newcomers are not strictly aware of: Expanding a ZFS pool is not always as straightforward as you think it should be ZFS was designed to be expanded, and it handled this very well However, a ZFS pool is made up of VDEVs, and it is these VDEVs that provide the redundancy. RAID-Z VDEVs cannot be changed once they are created. You can replace each disk individually, and the VDEV will grow to its new larger size, but you cannot add additional disks to a RAID-Z VDEV At this point, your option is to add an additional VDEV, although best practises dictate that the new VDEV should use an equal number of disks, to avoid uneven performance So, if you started with a 6 disk RAID-Z2, having to add 6 more disks to grow the pool does seem excessive For the best flexibility, use mirrors. If you had used 6 disks as 3 mirrors of 2 disks each, you could then just add 2 more disks at a time. The downside is that using 2TB disks, you'd only have 6TB of usable space, versus the 8TB you would get from those disks in a RAID-Z2 This is the trade-off, mirrors give you better performance and flexibility, but less space efficiency It is important to note that the diagrams in this article make it appear as if all parity information is stored on specific drives. In ZFS parity is spread across all drives. Often times, the data written to the drive is not of a size that can evenly be split across all drives, so the data actually ends up looking like this (http://blog.delphix.com/matt/files/2014/06/RAIDZ.png) The errors as I see it in the original article are: It notes that the hidden cost of ZFS is that if you add a second RAID-Z VDEV, you will have a whole second set of parity drives. While this is a cost, it is the cost of making sure your data is safe. If you had an array with more than 12 drives, it is likely that you would to be able to withstand the failure of the larger number of drives The article does not consider the resilver time. If you did create a configuration with a very wide RAID-Z stripe, the failure of a disk would leave the pool degraded for a much longer time, leaving your pool at risk for that longer period. The article does not consider performance. Two RAID-Z2 VDEVs of 6 disks each will give much better performance than a single VDEV of 10 or 12 disks, especially when it comes to IOPS. *** ZFS Boot Enviroments now availble in the FreeBSD bootloader (https://svnweb.freebsd.org/base?view=revision&revision=293001) It's been in phabricator for a while (and PC-BSD), but the support for Boot-Environments has now landed upstream in -CURRENT This work was helped by cross-project collaboration when an IllumOS Developer, Toomas Soome, started porting the FreeBSD loader to IllumOS to replace GRUB there This gives Beastie menu the ability to look at the ZFS disk, and dynamically list boot-environments that it finds. (Much nicer than GRUB, which required a pre-written configuration file) This work was extended further, when Toomas Soome also ported the Beastie Menu to the UEFI loader (https://svnweb.freebsd.org/base?view=revision&revision=293233) which is now enabled by default for UEFI (https://svnweb.freebsd.org/base?view=revision&revision=293234) All of these changes are scheduled to be merged back in time for FreeBSD 10.3 as well. There is also a patch being worked on to support booting from ZFS in UEFI (https://reviews.freebsd.org/D4515) This is exciting times for doing neat things with ZFS on root, these plus Allans forthcoming GELI support (https://reviews.freebsd.org/D4593) will negate the necessity for GRUB on PC-BSD for example (Kris is very happy) *** Interview - Josh Paetzel - email@email (mailto:email@email) / @bsdunix4ever (https://twitter.com/bsdunix4ever) ZFS Support *** News Roundup RetroBSD being tested on ESP32 (http://retrobsd.org/viewtopic.php?f=1&t=37470) More hardware news for RetroBSD and LiteBSD I don't know much about this hardware, but there is a lot of discussion in the forum threads about it Not sure what you are supposed to accomplish with only 400kb of ram LITEBSD Brings 4.4BSD to PIC32 (https://hackaday.com/2016/01/04/litebsd-brings-4-4bsd-to-pic32/) It is interesting to see these super-small boards with only 512kb of memory, but will crypto offload support It is also interesting to see talk of 140mbps WiFi, can the processor actually handle that much traffic? BSD Unix-like OS is Resurrected for Embedded IoT Market (http://thevarguy.com/open-source-application-software-companies/bsd-unix-os-resurrected-embedded-iot-market) Related to the above stories, we also have an article about BSD making a resurgence on various Internet of things devices, which mentions both RetroBSD and LiteBSD The article mentions that this is an exciting development for embedded vars who now have an alternative licensed open-source OS to potentially use *** HardenedBSD's new Binary Updater (https://hardenedbsd.org/article/shawn-webb/2015-12-31/introducing-hardenedbsds-new-binary-updater) It looks like there is now another way to update your FreeBSD(hardened) system The post by Shawn Web, details how the new updater will work in future releases of HBSD Right now it looks fairly straight-forward, creating both the base.txz and kernel.txz, along with some data for etcupdate It includes a nice option for the kernel name in the update, allowing different kernels to be installed / updated at will Everything is cryptographically signed and verified using the base system openssl The build system is fairly simple, only requiring “sh/git/openssl” to create the binary updates Planned features also include updating of jails, and ZFS boot-environments *** Sometimes, processors need (BSD) love too (http://functionallyparanoid.com/2016/01/02/sometimes-processors-need-love-too/) We have a blog post from Brian Everly, talking about his long journey into legacy processors and the plans for the future to work on better supporting them on OpenBSD ports He begins with the story of his UNIX journey to today, and why this fostered his love for many of these old (and not so old) architectures, such as Sparc64, PPC32, i386. This journey ended up with the purchase of some legacy hardware (ebay is your friend), and the creation of a database listing the major port blockers on each platform This is the great kind of thing folks can do to step up and help a project, even as a weekend hobby it's great to run some hardware and help test / fix up issues that other developers maybe don't interact with as much anymore. *** Beastie Bits The standard MWL disclaimer (http://blather.michaelwlucas.com/archives/2510) PC-BSD 11.0-CURRENTJAN2016 Available (http://lists.pcbsd.org/pipermail/testing/2016-January/010350.html) NetBSD pkgsrc-2015Q3 statistics (http://mail-index.netbsd.org/tech-pkg/2015/12/28/msg016193.html) NetBSD pkgsrc-2015Q4 released (http://mail-index.netbsd.org/tech-pkg/2016/01/01/msg016213.html) First Reproducible builds conference in Athens (http://blog.netbsd.org/tnf/entry/reproducible_builds_conference_in_athens) The creator of the original ThinkPad design passes away (http://www.theregister.co.uk/2016/01/06/thinkpad_designer_obituary) Feedback/Questions Andrew - High Contrast (http://slexy.org/view/s213iCKLwn) John - FreeNAS followup (http://slexy.org/view/s21ClGePLP) Giorgio - Custom Install (http://slexy.org/view/s21527pkO1) Don - ZFS Slowdowns (http://slexy.org/view/s2jOlCsjkU) Fred - Dual Boot PC-BSD/Linux (http://slexy.org/view/s21uaB0FDU) ***

La Universidad de Harvard está demostrando que es capaz de pensar “fuera de la caja”. ¿Cómo? Utilizando el medio de “tirilla cómica” como una de sus herramientas para educar. Y los resultados parecen ser prometedores. Seagate, una compañía líder en el mercado de discos duros acaba de introducir al mercado su modelo “enterprise level” de 6TB. Y una encuesta celebrada en los Estados Unidos por la empresa Harris demostró que más de dos terceras partes de los estadounidenses desconfían de las compañías de tecnología. Y el pasado martes, 8 de abril, Microsoft cesó de ofrecer apoyo técnico para Windows XP, el sistema operativo más popular en la historia de la empresa y el segundo en uso a nivel mundial. Por su parte, AT&T anunció que se propone dejar de ofrecer servicio telefónico terrestre a nivel nacional. Finalmente hablamos sobre la manera correcta y segura de limpiar la pantalla LCD de tu televisor o computadora. Además, incluimos un enlace a un artículo interesantísimo que nos envió Carlos Castillo, uno de nuestros oyentes, que se titula: “10 Razones Por La Que Los Niños No Deben Usar Electrónicos Portátiles Antes De Los 12 Años”. Si tienes niños pequeños, o nietos, te sugiero que lo leas.
