As a backend developer, you may not realize that Java was initially born on embedded devices like set-top boxes and gateways. We discussed this topic for the first time almost three years ago in Foojay Podcast #2 with James Gosling, Johan Vos, Erik Costlow, and Frank Delporte (https://foojay.io/today/foojay-podcast-2/).In this episode #55, we look into the history of the Java Micro Edition and how things evolved. Nowadays, with processors becoming increasingly powerful, we can run the exact same Java runtime on any Linux system, from the biggest cloud servers to the smallest Raspberry Pi Zero. Let's find out what can be done with Java in the embedded world.GuestsRobert von Burghttps://www.linkedin.com/in/eitchme/https://mstdn.gsi.li/@eitchDaShaun Carterhttps://www.linkedin.com/in/dashaun/https://twitter.com/dashaunhttps://vmst.io/@dashaunPavel Petroshenkohttps://www.linkedin.com/in/pavel-petroshenko-5220092/Content00:00 Introduction of the topic and guests04:53 Java is running on more devices than we can imagine06:18 History of Java MEhttps://www.oracle.com/java/technologies/javameoverview.html https://en.wikipedia.org/wiki/SavaJe Jasper S20: https://vimeo.com/198239375 Jasper S20: https://www.phonescoop.com/articles/article.php?a=77&p=1498 15:55 Java on modern embedded devices22:25 Are modern embedded devices still "embedded"?25:24 Current modern Java is perfect for embedded useshttps://www.pi4j.com 30:10 How Java moved to ARM on Mac and cloud34:48 Green Computing = Reducing costsPresentation by Miro Wengner: https://www.youtube.com/watch?v=zP4xeeY3HIA https://thenewstack.io/which-programming-languages-use-the-least-electricity/ 37:47 Recent Java evolutions impacting embedded use41:51 Is there a need for real-time Java?LED strips with Java: https://www.pi4j.com/examples/jbang/pixelblaze_output_expander/ 49:44 Spring IO presentation by DaShaunhttps://2024.springio.net/sessions/spring-boot-on-the-edge 51:38 Java on RISC-Vhttps://riscv.org/blog/2024/04/java-21-and-22-now-available-on-risc-v-a-collaboration-between-rise-and-eclipse-adoptium 53:27 More details about the product Robert develops with Javahttps://www.pi4j.com/featured-projects/soft-real-time-plc-written-in-strolch/ https://strolch.li/ 59:09 Network alternatives on embedded (e.g. LoRa)1:03:42 What will the future bring to embedded Java?Pi4J Spring Boot: https://www.youtube.com/watch?v=I62IviQLNts https://openjdk.org/projects/leyden/ https://openjdk.org/projects/crac/ 1:09:07 Conclusion

What A SHOW folks, I almost don't want to write anything in the newsletter to MAKE you listen haha but I will I know many of you don't like listening to be babble. But if you chose one episode to listen to instead of just skimming the show-notes, make it this one. We've had 2 deep dives, one into the exciting world of multi-modalilty, we chatted with the creator of Moondream1, Vik and the co-founders of Prophetic, Wes and Eric about their EEG/fMRI multimodal transformer (that's right!) and then we had a DEEP dive into the new Hourglass Diffusion Transformers with Tanishq from MedArc/Stability.

In todays episode I spoke with SeedSigner (The man), Keith Mukai (Lead Dev) and Nick Klockenga (Lead maintainer) about the recent updates to the Seed signer project. Before we dive into it lets remind ourselves what the seed signer project is and why its so important. What is SeedSigner? SeedSigner offers anyone the opportunity to build a verifiably air-gapped, stateless Bitcoin signing device using inexpensive, publicly available hardware components (usually < $50). SeedSigner helps users save with Bitcoin by assisting with trustless private key generation and multi-signature wallet setup, and helps users transact with Bitcoin via a secure, air-gapped QR-exchange signing model. You can use SeedSigner to complete these tasks: Calculate word 12/24 of a BIP39 seed phrase Create a 24-word BIP39 seed phrase with 99 dice rolls Create a 24-word BIP39 seed phrase by taking a digital photo Temporarily store up to 3 seed phrases while device is powered Guided interface to manually create a SeedQR for instant input BIP39 passphrase / word 25 support Native Segwit Multisig XPUB generation w/ QR display Scan and parse transaction data from animated QR codes Sign transactions & transfer XPUB data using animated QR codes Live preview during photo-to-seed and QR scanning UX Optimized seed word entry interface Support for Bitcoin Mainnet & Testnet Support for custom user-defined derivation paths On-demand receive address verification User-configurable QR code display density Responsive, event-driven user interface To build a SeedSigner you will need the following components. – Raspberry Pi Zero version 1.3 (not “W”) – Waveshare 1.3 LCD Hat (240 x 240 pixels) – Aokin / AuviPal/ (other) RPI Camera – “Orange Pill” Enclosure Now that we have reminded ourselves what the project is and why its here we can continue. What I love about SS is anyone in the world can build one without anybody knowing they have it, this is especially useful in countries where freedom money is not welcome. I've been following this project for a few years now and continue to be impressed by the vision and team. Since I last spoke to SS they have built a new operating system helping with faster boot times as well as reducing the attack surface. As well as talking technical updates we also discus the pros and cons of working with a fully open source project and why the team are so passionate about what they do. It was really interesting to hear how the three team members met and how they have been working together to help refine and build this incredible project. It was a pleasure speaking to the SeedSigner team and I hope you enjoy listening as much as I enjoyed recording this.

Happy 10th birthday Raspberry Pi! The tiny computer has come a long way in just ten short years. It all started when Raspberry Pi Foundation founders Eben Upton and Rob Mullins set out to create an affordable, easy-to-use computer that students could use to learn coding. And they succeeded - Raspberry Pi has become one of the most popular computers in the world, with millions of units sold.The Raspberry Pi HardwareThe first devices were not intended to be the massive platform they are today, Instead, the plan was simply to make a few thousand devices to encourage children to learn to code. Raspberry Pi devices were first sold in 2012, and the response was overwhelming. Not only did students love them, but makers and hobbyists snapped them up as well. It quickly became clear that there was a much larger market for the tiny computers than originally anticipated.The Raspberry Pi Foundation has always been focused on education, and they continue to work with schools and organizations around the world to promote coding and computer science education. In addition to their educational initiatives, they have also developed several tools and resources that have made it easier for makers of all levels to create amazing projects.Over the years, Raspberry Pi has undergone several iterations, each one more powerful than the last. The original Model B was followed by the Model B+, the Raspberry Pi Zero, the Raspberry Pi A+ and A series, the Raspberry Pi Compute Module, and the Raspberry Pi Model B+. Beyond that, there have been a whole lot more.The Raspberry Pi 4 is just one example of how much Raspberry Pi has changed over the years. The original Model B had just 256MB of RAM and a 700MHz single-core processor. The latest Raspberry Pi 4 has a quad-core processor clocked at up to 1.5 GHz, as well as 8 GB of RAM. It also features improved networking with dual-band 802.11ac Wi-Fi and Bluetooth Low Energy (BLE) on board.In addition to hardware changes, the Raspberry Pi Foundation has also made several changes to the operating system over the years. The original Raspberry Pi devices ran on a modified version of Debian Linux, but the Raspberry Pi Foundation later developed their own operating system, Raspbian. Raspbian is based on Debian and is optimized for the Raspberry Pi hardware. Since then, the platform has transferred to Raspberry Pi OS, another Linux-based operating system.The Raspberry Pi communityAs amazing as all of the changes to Raspberry Pi have been, perhaps the most impressive thing about the tiny computer is the community that has grown up around it. There are now millions of Raspberry Pi devices in use all over the world, and there are countless projects and applications for them.From small projects like retro gaming consoles and media centers to large-scale deployments like industrial control systems and weather stations, Raspberry Pi is being used for everything. The possibilities are truly endless, and the Raspberry Pi community continues to come up with new and innovative ways to use the tiny computers.As Raspberry Pi celebrates its tenth birthday, it's clear that the best is yet to come. Thank you for being a part of this incredible journey, and we can't wait to see what the next ten years have in store for Raspberry Pi.

We talk with mother/daughter team Miki and Kate Rezentes about their experiences learning and working with Elixir and as women in the tech industry. Miki presented “Greasing the Wheel of Adoption” at ElixirConf. Her focus was on the people aspect of adoption and we had a great time going deeper on that topic here. Kate, who is just starting her career as a developer, talks about ways we can share tech with the young people around us. We get their ideas and suggestions for ways to support women in tech, young people learning tech, and more!

Great Scott has a new video about synchronous switching converters that was great! Chris was hanging out with a friend in the chip industry, talking about power converters. Past guests at chip companies Matt Duff (ADI) Hank Zumbahlen (ADI) Mike Engelhardt (LT) There was a presentation by Werner Johansson about doing a digitally controlled power circuit using Atmel parts Should Dave be programming in Aussie++? It is now "officially endorsed" by Dave In Dave's 1024th video, he got really old code working Raspberry Pi Zero 2 W has been released and is "the most efficient" Mentoring exercise talking to a student looking to get hired, Chris mentioned the student should get lots of tools in their toolbelt Dave expanded on us talking about Flux.ai last week in a video on EEVblog2 about tools Chris is now looking for an engineering laptop, but it really doesn't have to be that different from a normal laptop The Framework laptop is modular, but how often will you use those features? Chris has been trying out the Sparkfun Micromod system, but thinks it will have limited usefulness Are modular standards doomed to fail over the long term? What are some good examples of a truly modular system? PC/104 is an older modular system discussed before (and is still around)

Over the past few weeks, there has been a bit of a roller coaster over at Raspberry Pi. Most recently, last week the organization announced that Raspberry Pi 4 boards would be going up in price by $10. But, this week, they are back with some good news - a brand new entry in the Zero family: the Raspberry Pi Zero 2 W.This is an upgrade over the existing Raspberry Pi Zero and Zero W. All three have the same board layout with the same ports and structure. This is important to the Raspberry Pi family, as it allows for one model to be switched out for another as new hardware is introduced, or inventory is made available. These days, the inventory levels would be the biggest concern. All of the boards support an SD card for storage and booting, mini HDMI for external display, and USB for power.The original Zero, which sells for $5, comes with no wireless connectivity. The Zero W adds Wi-Fi and Bluetooth to the mix and brings the price to $10. The new Zero 2 W maintains the wireless options, though only Wi-Fi N 2.4 GHz, but improves the on-board processing. This board takes the processor from a single-core processor to a quad-core ARM Cortex 853. Clearly, this is going to add a lot of new capabilities to the small form factor board that was simply not available before. This upgrade will only bring the price to $15. Unfortunately, the upgrade in processor does not come with an upgrade in RAM, leaving you at 512 MB.For example, while the older boards were simply not powerful enough to do any on-board AI processing, the new Zero 2 W can. In fact, it can process more than a single frame per second in object and facial recognition. The older boards were capable of some minor game emulation, but the new board is capable of getting up into the realm of a PlayStation 1. This makes it great for small game systems, even portable and handheld systems.But, why a Zero rather than the more powerful Raspberry Pi 4? The Zero family uses a lot less power, both in idle and in stressed circumstances. This means that your portable game system can run longer. It is also smaller, so it can be used in tight spaces, such as in a robot. It's also significantly cheaper, with the new model coming in at $15, versus the current $35 for the 1GB model of Raspberry Pi 4.The Zero 2 W joins a growing list of boards from the Raspberry Pi family. Currently, they have sold over 40 million of these boards around the world in the last 9+ years, since they first board debuted. As they grow in popularity, it is expected that the number will grow quicker. Avram has long said that everyone interested in electronics should own a Raspberry Pi, and this new model is in a great sweet spot for capabilities and price.

We talk with Peter Ullrich about his experience sending SMS messages from a Raspberry Pi Zero using Nerves. We cover what went well, what didn't and get a glimpse into the current state of Nerves for a newbie when dealing with hardware. Peter also tried Livebook for Nerves and had a great experience with that. We discuss the challenges of hardware systems dealing with the “real world” but see how Elixir makes the process easier to model and think about.

Special guest: Paul Everitt Brain #1: Why I use attrs instead of pydantic Tin Tvrtković, @tintvrtkovic attrs vs dataclasses Since dataclasses are a strict subset of attrs functionality. Recommend using attrs in most cases over dataclasses attrs is faster, has more features, releases more frequently, offers over a wider range of Python versions. attrs vs Pydantic attrs is a library for generating the boring parts of writing classes; Pydantic is that but also a complex validation library. a structuring/unstructuring library, ex converting to json and back attrs has opt-in validation that you have more control over cattrs can be used for structuring/unstructuring converters are opt-in for attrs, built into Pydantic, and can be wrong. example using Pendulum that Pydantic mishandles Summary attrs + cattrs + validators where necessary, converters where necessary will be faster you'll have more control Kind of a “small, sharp, specialized tools” vs “swiss army knife” comparison. Michael #2: mclfy via __dann__ Mcfly is an incredible Ctrl+r replacement McFly replaces your default ctrl-r shell history search with an intelligent search engine that takes into account your working directory and the context of recently executed commands. McFly's suggestions are prioritized in real time with a small neural network. Features Rebinds ctrl-r to bring up a full-screen reverse history search prioritized with a small neural network. Augments your shell history to track command exit status, timestamp, and execution directory in a SQLite database. Maintains your normal shell history file as well so that you can stop using McFly whenever you want. Includes a simple action to scrub any history item from the McFly database and your shell history files. Designed to be extensible for other shells in the future. Written in Rust, so it's fast and safe. Paul #3: Textual and boilerplate removal In the race to make Textual the most talked-about package in Python Bytes history… I'd like to zoom in on a Twitter discussion he had about removing boilerplate I have traditionally been opposed to the convention-over-configuration approach that most successful Python projects have taken I dislike magic variable and file names, prefer explicit is better than implicit, actual symbols Lately, because of…tooling But Will's approach to “boilerplate removal” is compelling, as it remains mypy friendly Still, I find it flawed…code meant to be read 2 years from now…that stuff that is implied-away, worries me Will is great at working-in-the-open, being a gentle, encouraging public figure Brian #4: xdoctest “The xdoctest package is a re-write of Python's builtin doctest module. It replaces the old regex-based parser with a new abstract-syntax-tree based parser (using Python's ast module). The goal is to make doctests easier to write, simpler to configure, and encourage the pattern of test driven development.” “The main enhancements xdoctest offers over doctest are: All lines in the doctest can now be prefixed with >>>. Old-style doctests with ... are still valid. Additionally, the multi-line strings don't require any prefix (but its ok if they do have either prefix). Tests are executed in blocks, rather than line-by-line, thus comment-based directives (e.g. # doctest: +SKIP) are now applied to an entire block, rather than just a single line. Tests without a "want" statement will ignore any stdout / final evaluated value. This makes it easy to use simple assert statements to perform checks in code that might write to stdout. If your test has a "want" statement and ends with both a value and stdout, both are checked, and the test will pass if either matches. Output from multiple sequential print statements can now be checked by a single "got" statement. (new in 0.4.0).” Features I love “The new got/want tester is very permissive by default; it ignores differences in whitespace” You can make doctest normalize whitespace, but why should you have to? Michael #5: Automate the standing desk with python via Joe Riedley, by David Kong “When I first started using it, I was very excited, but I quickly found myself sitting all day, in spite of the fancy desk.” I took off a few screws and … voila! A row of pins neatly exposed right in front. The pins in my control box, when connected correctly, simulate the pressing of the buttons on the front of the box. Raspberry Pi Zero, the simplest, most basic version. It doesn't have all the bells and whistles, but it does everything I needed for this simple project, and it's just $5(!). And the code from gpiozero import LED # The LED library allows easy pin control from time import sleep import randomrelay = LED(17) # I connected the relay to pin 17 and groundwhile True: relay.on() sleep(1) relay.off() sleep(random.randint(45, 60) * 60) Paul #6: Hypermodern Python Cookiecutter I've been noodling with some code the last two years about bringing frontend DX to Python web dev Learning and talking more than adoption Running a modern Python project is a LOT of housekeeping Hypermodern Python Cookiecutter from Claudio Jolowicz teleported me to a state of the art I was looking for Poetry, Nox, GHA, pre-commit, flake8, PyPI uploads from CI, release drafter, Black, prettier, pytest, mypy, Sphinx and friends, GitHub labeler It's NOT AT ALL just a cookiecutter The best part…it's an enormously-detailed user guide, some blog posts with the “why”, it's actively maintained The PR workflow is really well explained and wired up This could be…a course, a webinar Thanks Claudio Extras Michael: ActiveState's 2021 Software Supply Chain Security Survey Python 3.9.7 and 3.8.12 are now available From Shlomi Lanton, on your #2 Brian talked about having a history of all files to find the ones that were updated last, so I created granpa caffinate: you mentioned the MacOS /usr/bin/caffeinate tool on "https://pythonbytes.fm/episodes/show/247/do-you-dare-to-press-.".

This week we have a FreeBSD Foundation development update, tell you about sprinkling in the TrueOS project, Dynamic WDS & a whole lot more! This episode was brought to you by Headlines OpenSSH Removes SSHv1 Support (http://undeadly.org/cgi?action=article&sid=20170501005206) In a series of commits starting here (http://marc.info/?l=openbsd-cvs&m=149359384905651&w=2) and ending with this one (http://marc.info/?l=openbsd-cvs&m=149359530105864&w=2), Damien Miller completed the removal of all support for the now-historic SSHv1 protocol from OpenSSH (https://www.openssh.com/). The final commit message, for the commit that removes the SSHv1 related regression tests, reads: Eliminate explicit specification of protocol in tests and loops over protocol. We only support SSHv2 now. Dropping support for SSHv1 and associated ciphers that were either suspected to or known to be broken has been planned for several releases, and has been eagerly anticipated by many in the OpenBSD camp. In practical terms this means that starting with OpenBSD-current and snapshots as they will be very soon (and further down the road OpenBSD 6.2 with OpenSSH 7.6), the arcane options you used with ssh (http://man.openbsd.org/ssh) to connect to some end-of-life gear in a derelict data centre you don't want to visit anymore will no longer work and you will be forced do the reasonable thing. Upgrade. FreeBSD Foundation April 2017 Development Projects Update (https://www.freebsdfoundation.org/blog/april-2017-development-projects-update/) FreeBSD runs on many embedded boards that provide a USB target or USB On-the-Go (OTG) interface. This allows the embedded target to act as a USB device, and present one or more interfaces (USB device classes) to a USB host. That host could be running FreeBSD, Linux, Mac OS, Windows, Android, or another operating system. USB device classes include audio input or output (e.g. headphones), mass storage (USB flash drives), human interface device (keyboards, mice), communications (Ethernet adapters), and many others. The Foundation awarded a project grant to Edward Tomasz Napierała to develop a USB mass storage target driver, using the FreeBSD CAM Target Layer (CTL) as a backend. This project allows FreeBSD running on an embedded platform, such as a BeagleBone Black or Raspberry Pi Zero, to emulate a USB mass storage target, commonly known as a USB flash stick. The backing storage for the emulated mass storage target is on the embedded board's own storage media. It can be configured at runtime using the standard CTL configuration mechanism – the ctladm(8) utility, or the ctl.conf(5) file. The FreeBSD target can now present a mass storage interface, a serial interface (for a console on the embedded system), and an Ethernet interface for network access. A typical usage scenario for the mass storage interface is to provide users with documentation and drivers that can be accessed from their host system. This makes it easier for new users to interact with the embedded FreeBSD board, especially in cases where the host operating system may require drivers to access all of the functionality, as with Windows and OS X. They provide instructions on how to configure a BeagleBone Black to act as a flash memory stick attached to a host computer. +Check out the article, test, and report back your experiences with the new USB OTG interface. *** Spring cleaning: Hardware Update and Preview of upcoming TrueOS changes (https://www.trueos.org/blog/spring-cleaning-hardware-update-preview-upcoming-trueos-changes/) The much-abused TrueOS build server is experiencing some technical difficulties, slowing down building new packages and releasing updates. After some investigation, one problem seemed to be a bug with the Poudriere port building software. After updating builders to the new version, some of the instability is resolved. Thankfully, we won't have to rely on this server so much, because… We're getting new hardware! A TrueOS/Lumina contributor is donating a new(ish) server to the project. Special thanks to TrueOS contributor/developer q5sys for the awesome new hardware! Preview: UNSTABLE and Upcoming TrueOS STABLE update A fresh UNSTABLE release is dropping today, with a few key changes: Nvidia/graphics driver detection fixes. Boot environment listing fix (FreeBSD boot-loader only) Virtual box issues fixed on most systems. There appears to be a regression in VirtualBox 5.1 with some hardware. New icon themes for Lumina (Preferences -> Appearance -> Theme). Removal of legacy pc-diskmanager. It was broken and unmaintained, so it is time to remove it. Installer/.iso Changes (Available with new STABLE Update): The text installer has been removed. It was broken and unmaintained, so it is time to remove it. There is now a single TrueOS install image. You can still choose to install as either a server or desktop, but both options live in a single install image now. This image is still available as either an .iso or .img file. The size of the .iso and .img files is reduced about 500 Mb to around 2Gb total. We've removed Firefox and Thunderbird from the default desktop installation. These have been replaced with Qupzilla and Trojita. Note you can replace Qupzilla and Trojita with Firefox and Thunderbird via the SysAdm Appcafe after completing the TrueOS install. Grub is no longer an installation option. Instead, the FreeBSD boot-loader is always used for the TrueOS partition. rEFInd is used as the master boot-loader for multi-booting; EFI partitioning is required. Qpdfview is now preinstalled for pdf viewing. Included a slideshow during the installation with tips and screenshots. Interview - Patrick M. Hausen - hausen@punkt.de (mailto:hausen@punkt.de) Founder of Punkt.de HAST - Highly Available Storage (https://wiki.freebsd.org/HAST) News Roundup (finally) investigating how to get dynamic WDS (DWDS) working in FreeBSD! (http://adrianchadd.blogspot.com/2017/04/finally-investigating-how-to-get.html) Adrian Chadd writes in his blog: I sat down recently to figure out how to get dynamic WDS working on FreeBSD-HEAD. It's been in FreeBSD since forever, and it in theory should actually have just worked, but it's extremely not documented in any useful way. It's basically the same technology in earlier Apple Airports (before it grew into what the wireless tech world calls "Proxy-STA") and is what the "extender" technology on Qualcomm Atheros chipsets implement. A common question I get from people is "why can't I bridge multiple virtual machines on my laptop and have them show up over wifi? It works on ethernet!" And my response is "when I make dynamic WDS work, you can just make this work on FreeBSD devices - but for now, use NAT." That always makes people sad. + Goes on to explain that normal station/access point setups have up to three addresses and depending on the packet type, these can vary. There are a couple of variations in the addresses, which is more than the number of address fields in a normal 802.11 frame. The big note here is that there's not enough MAC addresses to say "please send this frame to a station MAC address, but then have them forward it to another MAC address attached behind it in a bridge." That would require 4 mac addresses in the 802.11 header, which we don't get. .. except we do. There's a separate address format where from-DS and to-DS bits in the header set to 1, which means "this frame is coming from distribution system to a distribution system", and it has four mac addresses. The RA is then the AP you're sending to, and then a fourth field indicates the eventual destination address that may be an ethernet device connected behind said STA. If you don't configure up WDS, then when you send frames from a station from a MAC address that isn't actually your 802.11 interface MAC address, the system would be confused. The STA wouldn't be able to transmit it easily, and the AP wouldn't know how to get back to your bridged ethernet addresses. The original WDS was a statically configured thing. [...] So for static configurations, this works great. You'd associate your extender AP as a station of the central AP, it'd use wpa_supplicant to setup encryption, then anything between that central AP and that extender AP (as a station) would be encrypted as normal station traffic (but, 4-address frame format.) But that's not very convenient. You have to statically configure everything, including telling your central AP about all of your satellite extender APs. If you want to replace your central AP, you have to reprogram all of your extenders to use the new MAC addresses. So, Sam Leffler came up with "dynamic WDS" - where you don't have to explicitly state the list of central/satellite APs. Instead, you configure a central AP as "dynamic WDS", and when a 4-address frame shows up from an associated station, it "promotes" it to a WDS peer for you. On the satellite AP, it will just find an AP to communicate to, and then assume it'll do WDS and start using 4-address frames. It's still a bit clunky (there's no beacon, probe request, etc IEs that say "I do dynamic WDS!" so you'd better make ALL your central APs a different SSID!) but it certainly is better than what we had. Firstly, there are scripts in src/tools/tools/net80211/ - setup.wdsmain and setup.wdsrelay. These scripts are .. well, the almost complete documentation on a dynamic WDS setup. The manpage doesn't go into anywhere near enough information. So I dug into it. It turns out that dynamic WDS uses a helper daemon - 'wlanwds' - which listens for dynamic WDS configuration changes and will do things for you. This is what runs on the central AP side. Then it started making sense! So far, so good. I followed that script, modified it a bit to use encryption, and .. well, it half worked. Association worked fine, but no traffic was passing. A little more digging showed the actual problem - the dynamic WDS example scripts are for an open/unencrypted network. If you are using an encrypted network, the central AP side needs to enable privacy on the virtual interfaces so traffic gets encrypted with the parent interface encryption keys. Now, I've only done enough testing to show that indeed it is working. I haven't done anything like pass lots of traffic via iperf, or have a mix of DWDS and normal STA peers, nor actually run it for longer than 5 minutes. I'm sure there will be issues to fix. However - I do need it at home, as I can't see the home AP from the upstairs room (and now you see why I care about DWDS!) and so when I start using it daily I'll fix whatever hilarity ensues. Why don't schools teach debugging? (https://danluu.com/teach-debugging/) A friend of mine and I couldn't understand why some people were having so much trouble; the material seemed like common sense. The Feynman Method was the only tool we needed. Write down the problem Think real hard Write down the solution The Feynman Method failed us on the last project: the design of a divider, a real-world-scale project an order of magnitude more complex than anything we'd been asked to tackle before. I understand now why half the class struggled with the earlier assignments. Without an explanation of how to systematically approach problems, anyone who didn't intuitively grasp the correct solution was in for a semester of frustration. People who were, like me, above average but not great, skated through most of the class and either got lucky or wasted a huge chunk of time on the final project. I've even seen people talented enough to breeze through the entire degree without ever running into a problem too big to intuitively understand; those people have a very bad time when they run into a 10 million line codebase in the real world. The more talented the engineer, the more likely they are to hit a debugging wall outside of school. It's one of the most fundamental skills in engineering: start at the symptom of a problem and trace backwards to find the source. It takes, at most, half an hour to teach the absolute basics – and even that little bit would be enough to save a significant fraction of those who wash out and switch to non-STEM majors. Why do we leave material out of classes and then fail students who can't figure out that material for themselves? Why do we make the first couple years of an engineering major some kind of hazing ritual, instead of simply teaching people what they need to know to be good engineers? For all the high-level talk about how we need to plug the leaks in our STEM education pipeline, not only are we not plugging the holes, we're proud of how fast the pipeline is leaking. FreeBSD: pNFS server for testing (https://lists.freebsd.org/pipermail/freebsd-fs/2017-April/024702.html) Rick Macklem has issued a call for testing his new pNFS server: I now have a pNFS server that I think is ready for testing/evaluation. It is basically a patched FreeBSD-current kernel plus nfsd daemon. If you are interested, some very basic notes on how it works and how to set it up are at: http://people.freebsd.org/~rmacklem/pnfs-planb-setup.txt (http://people.freebsd.org/~rmacklem/pnfs-planb-setup.txt) A Plan B pNFS service consists of a single MetaData Server (MDS) and K Data Servers (DS), all of which would be recent FreeBSD systems. Clients will mount the MDS as they would a single NFS server. When files are created, the MDS creates a file tree identical to what a single NFS server creates, except that all the regular (VREG) files will be empty. As such, if you look at the exported tree on the MDS directly on the MDS server (not via an NFS mount), the files will all be of size == 0. Each of these files will also have two extended attributes in the system attribute name space: pnfsd.dsfile - This extended attrbute stores the information that the MDS needs to find the data storage file on a DS for this file. pnfsd.dsattr - This extended attribute stores the Size, ModifyTime and Change attributes for the file. For each regular (VREG) file, the MDS creates a data storage file on one of the K DSs, in one of the dsNN directories. The name of this file is the file handle of the file on the MDS in hexadecimal. The DSs use 20 subdirectories named "ds0" to "ds19" so that no one directory gets too large. At this time, the MDS generates File Layout layouts to NFSv4.1 clients that know how to do pNFS. For NFS clients that do not support NFSv4.1 pNFS, there will be a performance hit, since the IO RPCs will be proxied by the MDS for the DS server the data storage file resides on. The current setup does not allow for redundant servers. If the MDS or any of the K DS servers fail, the entire pNFS service will be non-functional. Looking at creating mirrored DS servers is planned, but it may be a year or more before that is implemented. I am planning on using the Flex File Layout for this, since it supports client side mirroring, where the client will write to all mirrors concurrently.

Summary of the preliminary LLDB support project (http://blog.netbsd.org/tnf/entry/summary_of_the_preliminary_lldb) What has been done in NetBSD Verified the full matrix of combinations of wait(2) and ptrace(2) in the following GNU libstdc++ std::call_once bug investigation test-cases Improving documentation and other minor system parts Documentation of ptrace(2) and explanation how debuggers work Introduction of new siginfo(2) codes for SIGTRAP New ptrace(2) interfaces What has been done in LLDB Native Process NetBSD Plugin The MonitorCallback function Other LLDB code, out of the NativeProcessNetBSD Plugin Automated LLDB Test Results Summary Plan for the next milestone fix conflict with system-wide py-six add support for auxv read operation switch resolution of pid -> path to executable from /proc to sysctl(7) recognize Real-Time Signals (SIGRTMIN-SIGRTMAX) upstream !NetBSDProcessPlugin code switch std::callonce to llvm::callonce add new ptrace(2) interface to lock and unlock threads from execution switch the current PTWATCHPOINT interface to PTGETDBREGS and PT_SETDBREGS Actually building a FreeBSD Phone (https://hackaday.io/project/13145-bsd-based-secure-smartphone) There have been a number of different projects that have proposed building a FreeBSD based smart phone This project is a bit different, and I think that gives it a better chance to make progress It uses off-the-shelf parts, so while not as neatly integrated as a regular smartphone device, it makes a much better prototype, and is more readily available. Hardware overview: X86-based, long-lasting (user-replaceable) battery, WWAN Modem (w/LTE), 4-5" LCD Touchscreen (Preferably w/720p resolution, IPS), upgradable storage. Currently targeting the UDOO Ultra platform. It features Intel Pentium N3710 (2.56GHz Quad-core, HD Graphics 405 [16 EUs @ 700MHz], VT-x, AES-NI), 2x4GB DDR3L RAM, 32GB eMMC storage built-in, further expansion w/M.2 SSD & MicroSD slot, lots of connectivity onboard. Software: FreeBSD Hypervisor (bhyve or Xen) to run atop the hardware, hosting two separate hosts. One will run an instance of pfSense, the "World's Most Popular Open Source Firewall" to handle the WWAN connection, routing, and Firewall (as well as Secure VPN if desired). The other instance will run a slimmed down installation of FreeBSD. The UI will be tweaked to work best in this form factor & resources tuned for this platform. There will be a strong reliance on Google Chromium & Google's services (like Google Voice). The project has a detailed log, and it looks like the hardware it is based on will ship in the next few weeks, so we expect to see more activity. *** News Roundup NVME M.2 card road tests (Matt Dillon) (http://lists.dragonflybsd.org/pipermail/users/2017-March/313261.html) DragonFlyBSD's Matt Dillon has posted a rundown of the various M.2 NVMe devices he has tested SAMSUNG 951 SAMSUNG 960 EVO TOSHIBA OCZ RD400 INTEL 600P WD BLACK 256G MYDIGITALSSD PLEXTOR M8Pe It is interesting to see the relative performance of each device, but also how they handle the workload and manage their temperature (or don't in a few cases) The link provides a lot of detail about different block sizes and overall performance *** ZREP ZFS replication and failover (http://www.bolthole.com/solaris/zrep/) "zrep", a robust yet easy to use ZFS based replication and failover solution. It can also serve as the conduit to create a simple backup hub. The tool was originally written for Solaris, and is written in ksh However, it seems people have used it on FreeBSD and even FreeNAS by installing the ksh93 port Has anyone used this? How does it compare to tools like zxfer? There is a FreeBSD port, but it is a few versions behind, someone should update it We would be interested in hearing some feedback *** Catching up on some TrueOS News TrueOS Security and Wikileaks revelations (https://www.trueos.org/blog/trueos-security-wikileaks-revelations/) New Jail management utilities (https://www.trueos.org/blog/new-jail-management-utilities/) Ken Moore's talk about Sysadm from Linuxfest 2016 (https://www.youtube.com/watch?v=PyraePQyCGY) The Basics of using ZFS with TrueOS (https://www.trueos.org/blog/community-spotlight-basics-using-zfs-trueos/) *** Catching up on some OpenBSD News OpenBSD 6.1 coming May 1 (https://www.openbsd.org/61.html) OpenBSD Foundation 2016 Fundraising (goal: $250K actual: $573K) (http://undeadly.org/cgi?action=article&sid=20170223044255) The OpenBSD Foundation 2017 Fundraising Campaign (http://www.openbsdfoundation.org/campaign2017.html) OpenBSD MitM attack against WPA1/WPA2 (https://marc.info/?l=openbsd-announce&m=148839684520133&w=2) OpenBSD vmm/vmd Update (https://www.openbsd.org/papers/asiabsdcon2017-vmm-slides.pdf) *** Beastie Bits HardenedBSD News: Introducing CFI (https://hardenedbsd.org/article/shawn-webb/2017-03-02/introducing-cfi) New version of Iocage (Python 3) on FreshPorts (https://www.freshports.org/sysutils/py3-iocage/) DragonFly BSD Network performance comparison as of today (https://leaf.dragonflybsd.org/~sephe/perf_cmp.pdf) KnoxBUG recap (http://knoxbug.org/content/knoxbug-wants-you) *** Feedback/Questions Noel asks about moving to bhyve/jails (https://pastebin.com/7B47nuC0) ***
