This week's EYE ON NPI is a powerful pocket-sized 'puter - it's the new PocketBeagle 2 from beagleboard.org! (https://www.digikey.com/en/product-highlight/b/beagleboard/pocketbeagle-2) This is a nice update from the beagleboard team to replace the deprecated PocketBeagle (https://www.digikey.com/short/bcmnqt01) - this new version gives you a lot more processor power at a much lower price. It's perfect when you want a full-featured single-board computer with a ton of GPIO and analog inputs, in a very smol package for easy integration. The PocketBeagle 2 is built around a TI Sitara AM6232 (https://www.digikey.com/short/83md98qd) dual-core Cortex-A53 plus dual Cortex-M4 subprocessor, with 512MB of external DDR4 SRAM. There's 4 MB of onboard eMMC flash, plus a socket for external microSD cards. There's also essentials like USB C for the native device, and a picoprobe-compatible (https://www.digikey.com/short/fq4wmp2b) UART port. What's great about the PocketBeagle 2 (https://www.digikey.com/short/17jh4q7b) is that compared to many single-board computers, the design is fully open source (https://github.com/beagleboard/pocketbeagle-2) verified-and-tested, so if you want to design your own board to add or remove peripherals/components, you can just pick up an AM6232 (https://www.digikey.com/short/83md98qd) from DigiKey and route your own design. Of course, with the high density BGA chip design, it's for experts: many makers and small-scale designers will be better off just adding the 2x18 Cape Headers (https://docs.beagle.cc/boards/pocketbeagle-2/04-expansion.html) which give you a ton of power and GPIO. For example, if you want to connect an external USB device to the host peripheral, those pins plus power and ground are on P1. If you want to connect a TTL graphical display (https://www.digikey.com/short/z9mfvzr8), the HSYNC/VSYNC/DE/Data pins are all on the P1/P2 - they're called VOUT. There's also multiple I2C and SPI ports and analog inputs. The PocketBeagle 2 (https://www.digikey.com/short/17jh4q7b) is back compatible with older peripherals you can pick up to get started designing 'Capes' (the name used for plug-in peripherals). Since the boards use 0.1" socket headers, its easy to prototype with jumper wires or DIY a design with simple CAD software and hand soldering. You can check out the GamePup (https://www.digikey.com/short/n2pp834m)which shows how to connect USB host, external battery, TFT display and lots of buttons. Or the TechLab (https://www.digikey.com/short/852dqn2c) which has 7-segment display, buzzer, USB serial and host, PWM'able RGB LED and I2C accelerometer. (https://www.beagleboard.org/boards/techlab) There's open source design files that you can use to kickstart your own Pocket Cape design (https://github.com/beagleboard/capes/tree/master/pocketbeagle/TechLab) Best of all, the PocketBeagle 2 (https://www.digikey.com/short/17jh4q7b) from beagleboard.org is almost half the price of the original PocketBeagle...and DigiKey has them in stock right now for instant shipment! Book today and you'll have a tiny and powerful single board Linux computer in your pocket by tomorrow afternoon. And don't forget... next week, June 19 2025, there's a webinar you can join to learn more (https://event.on24.com/wcc/r/4906084/A19039CF9E3C1ED0F430C14932B23630?partnerref=nph) about how to use the PocketBeagle 2 - it's free and run by the folks who designed the board, so register to get a reminder and watch!

This week's EYE ON NPI is a sweet valentine, as the Bard famously spoke "What's in a connector? That which we call a Hirose DF40F Series Board-to-Board connector by any other word would smell as sweet" (https://en.wikipedia.org/wiki/A_rose_by_any_other_name_would_smell_as_sweet). OK, well, maybe we chocolate-fudged that reference a bit but it's still a perfect day for lovers of reliable products from Hirose as today we're looking at the Hirose DF40F and friends (https://www.digikey.com/en/product-highlight/h/hirose/df40f-series-board-to-board-connectors) - diamond-rock solid connectors that mate together perfectly like perfect partners. Ok, I know your number one question, it's how to pronounce Hirose (https://www.youtube.com/watch?v=v4wd9qEZV5A) - is it "high rose"? We got ya, it's "hero say"! And they are definitely heroes when it comes to designing connectors, with well-thought-out components that you probably use all the time. For example, did you know that the ultra-popular u.FL connector (https://www.digikey.com/en/product-highlight/h/hirose/ufl-series) used almost in every RF product is from Hirose (https://en.wikipedia.org/wiki/Hirose_U.FL), patented by them in 1993 (https://patents.google.com/patent/US5180315)? Hirose DF40 connectors have popped up in many developer boards, due to their high density and ease-of-use. The first time we saw them was on the Intel Edison boards (https://en.wikipedia.org/wiki/Intel_Edison), which featured a 70-pin DF40 (https://www.adafruit.com/product/2227) for high speed USB or SDIO interfaces. More recently, the same DF40 family is seen on the popular Raspberry Pi Compute Module 4 (https://www.digikey.com/en/products/detail/raspberry-pi/SC0696/13530919), as dual 100 pin connectors that pass USB, Ethernet, PCIe, eMMC, DVI, DSI and CSI MIPI, and DPI parallel TFT displays. You can check out Shawn Hymel's guide on making an adapter board for the CM4 if you want tips on laying out and soldering DF40's (https://www.digikey.com/en/maker/projects/creating-a-raspberry-pi-compute-module-4-cm4-carrier-board-in-kicad/7812da347e5e409aa28d59ea2aaea490) And looking at the specs for the DF40 series (https://www.hirose.com/product/series/DF40) we see that these connectors are very well 'rounded': they can handle high voltages like 30V AC or DC, high speeds up to 10 Gbps, and fairly high currents 0.3A per pin - just double or triple up pins if you need more current capacity. That means you don't need separate power connectors and can power single board linux computers like the CM4 directly over the same connectors that pass HDMI and PCIe data for reliable and compact connectivity. Compared to 2.54mm or 2mm pitch headers, you don't have to worry about pins getting bent or the high offset height from IDC connectors because the Hirose DF40 series can be as low as 2mm, or as high as 4mm if you need height for component clearance. They're good for at least 30 mating cycles, with grooves to help align for easy mate and de-mate, just make sure to press down flat in the center and lift from two opposite edges so you minimize torque. If you have a submodule or multi-stacked board design and you need a low-profile, high-speed and high-power connector, the Hirose DF40F series of board-to-board connectors (https://www.digikey.com/short/dnr4r5j1) is trusted and reliable by many. I think of Hirose as the "YKK Zippers" of connectors (https://ykkamericas.com/products/zippers/): if you design a $100 board and it fails because of a poorly crafted $1 connector, the quality and reputation of your product is damaged - but if you use a reliable, enjoyable connector that makes good contact each time, the quality and reputation is enhanced! You can order DF40 and DF40F series in a wide series of sizes and configurations from DigiKey (https://www.digikey.com/short/dt70d4t0) all in stock right now and available for immediate shipment, like FTD (https://www.ftd.com/). Book today and your favorite Hirose connectors will ship instantly so that you can get to stacking and snapping by tomorrow afternoon.

This week's EYE ON NPI will stick by your side like a faithful hound- it's the BeagleBoard.org BeaglePlay® Single Board Computer (https://www.digikey.com/en/product-highlight/b/beagleboard/beagleplay). Single Board Computers (SBCs) are like tiny computers that are less powerful than desktops but much better at booting quickly and interfacing with hardware. They also tend to run Linux or BSD because it's easier to get those OS's ported to new chipsets than convincing Apple or Microsoft! This new generation of SBC from BeagleBoard builds on their prior success with the BeagleBoard (https://www.digikey.com/short/1cmb3dtf) and BeagleBone (https://www.digikey.com/short/c52dpz47) by adding a ton more interfaces and connectors so many projects can be built with no soldering. Here's a bullet list to get us started: AM6254 SoC processor 16 GB eMMC storage 2 GB DDR4 memory Supports expansion with OLDI, 4-lane CSI, and QWIIC connectors CSI for compatibility with the BeagleBone AI-654, Raspberry Pi Zero W, and compute modules Full-size HDMI connector Small size: 8 cm x 8 cm USB Type-C® with 5 V @ 3 A input connector mikroBUS connector RJ45 Ethernet connector for Gigabit Ethernet Wi-Fi 2.4 GHz and 5 GHz capabilities BLE and SubG MicroSD slot USB Type-A connector at 480 Mbit Grove connector The main processor is the TI Sitara AM6254 (https://www.digikey.com/short/507rmwr2) with quad-core 64-bit A53 and a Cortex M4 coprocessor. This chip is paired with 2 GB of DDR4 RAM and 16 GB of eMMC storage for a powerful AI-ready chipset that has tons of onboard graphics support such as 1080P HDMI and 4 lanes of OLDI/LVDS. This chip has 9x UARTS, 5x SPIs, 6x I2C's, 3x PWM modules, 3x quad encoders, and 3x CAN-FD, and of course some GPIO. Note there's no ADC or DAC - you'd use SPI to connect those externally. Note this board doesn't have a 2x20 header like a Raspberry Pi, or even the dual header strips from the BeagleBone - but in exchange it stuffs a ton of hardware support directly onto the PCB. For example, if you'd like to add a camera, there's an onboard 22-pin 0.5mm pitch CSI FPC connector that is compatible with the Pi Zero camera cables (https://www.adafruit.com/product/5211) - use that adapter to interface with any low cost Pi Camera modules or compatibles. For video output, a vertical full-sized HDMI port will connect to any monitor or display. In fact we plugged in our desktop monitor and powered the Play with a USB wall adapter, and it immediately came up with an X desktop display. Mouse and keyboard can be added via the USB 2.0 socket, a mini hub will allow multiple devices since there's only one type A port. The BeaglePlay does a great job of including everything you may want to expand your Raspberry Pi with. For example, there's a BQ32002 Real Time Clock (https://www.digikey.com/short/p0h10jbq) with a CR1220 coin cell holder right on board - normally that would have to be included as a separate module. A microSD card slot can be used for storing large amounts of data: unlike most SBCs, there's onboard 16GB eMMC so you don't have to juggle SD cards to install the OS. There's also a ton of expansion ports! For I2C, the onboard QWICC (https://www.sparkfun.com/qwiic) JST SH connector lets you use the hundreds of SparkFun sensors as well as any Adafruit Stemma QT (https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma) devices. For UART/PWM/ADC/I2C/GPIO you can use the onboard Grove connector. Finally, for networking either to the Internet or to a sensor network, there's Gigabit Ethernet, WiFi 2.4G and 5G, BLE and Sub-G networking. Yeah that's a lot! It's almost all provided by the onboard TI SimpleLink CC1352P7 (https://www.ti.com/product/CC1352P7) which boasts support for 6LoWPAN, Amazon Sidewalk, Bluetooth 5.2 Low Energy, IEEE 802.15.4, MIOTY, Proprietary 2.4 GHz, Thread, Wi-SUN NWP, Wireless M-Bus (T, S, C, N mode), Zigbee. Note LoRa is not in there, so if you need LoRa that would be added with a separate module. There's also an RJ-11 with Single-Pair Ethernet (https://blog.adafruit.com/2020/08/27/eye-on-npi-harting-single-pair-ethernet-eyeonnpi-digikey-ethernet-digikey-harting-adafruit/) which makes this a good fit to connect to industrial robotics or automation. All this hardware is available at a great price of under $100 at Digi-Key, we already picked one up and we're going to try and get Blinka working on it (https://github.com/adafruit/Adafruit_Blinka) so that all of our CircuitPython libraries will 'just run' in CPython. Especially given the ready-to-run Stemma QT / Qwiic port on the side, this is an excellent board for a powerful but solder-free configurable SBC. Digi-Key has tons of BeaglePlay's stock for immediate shipment, so order today (https://www.digikey.com/short/jpztmq3w) and you will be playing with your new BeaglePlay by tomorrow afternoon.
Why the PBP? Lately I've been thinking a lot about power consumption when it comes to computing. Intuitively, I know that arm devices pull significantly less power than amd64 machines but I've never really tested this in the real world. So, some preliminary power consumption stats: big amd64 laptops (thinkpad x220 and t490) pull at most 65 watts small arm SOCs typically pull at most 15 watts most android phones pull at most 18 watts Pentium 4 pulls at most 250 watts These numbers are fairly easy to find: just look at the power supply for a MAXIMUM OUTPUT value or something similar. This is the point at which the power supply fails so we can safely assume this is the maximum power draw for any given computer. Of course, this is DC output and not AC output and anyone who knows anything about electricity knows that converting AC to DC is expensive but these values are useful as a general estimate. I wrote something similar about computer power consumption some time ago My goal in all of this was to find a self contained computer that runs UNIX, doesn't take much power, isn't a consumption rectangle (smartphone), and can be charged from both AC with a rectifier and stored DC without an inverter. Charging from existing stored power was probably the most novel consideration. Everything else is a given. A few obvious answers come to mind: Raspberry Pi 4 is not self contained and using a pitop in public is a good way to get the bomb squad called on you beaglebone black is good too but neither self contained nor popular enough for wide OS support Pinebook Pro is self contained and is supported by some of the operating systems I'd like to run The PBP is an obvious choice. It's an open hardware ARM laptop that can be charged via a barrel cable (AC->DC) or via USB-C. Charging from USB-C is a very useful feature because it means I can easily choose between charging from the mains where efficiency loss is acceptable and charging from a DC source where efficiency loss is unacceptable. The actual use case is "what computer can I run off of a old car battery or the alternator in my car without burning power with an inverter?". I'll revisit this use case in a later section. Initial notes I took these notes immediately upon opening the PBP. They remain unedited because I want to be honest on the first impressions. shipping I was worried about DHL dropping my package out of a plane. Or leaving it out in the rain. Or having one of the employees use it as a soccer ball. Or having the thing get stuck in customs. It ended up arriving safely and was packaged well. Two boxes within a padded envelope within another envelope. Surprising for DHL. hardware impressions Touchpad sucks and trackpad scrolling sucks (it's probably just KDE). Installing synaptics drivers allegedly fix this problem. keyboard is comfortable, clickly, full sized despite being a chicklet keyboard. I don't like that the and keys are backwards when compared to a thinkpad. I really like the thinkpad keyboard layout. Shift+enter seems to type the M character. My muscle memory for key chording is now broken. This appears to be a fundamental design flaw with KDE. Passively cooled, gets a bit warm. display is sharp (IPS) and almost too high resolution for my eyes (1920x1080 instead of 1366x768). I can fix this in software. enabling/disabling mic/wifi/camera through the keyboard is confusing and (seemingly) does not perform the "kill switch" via hotplugging like the Thinkpad X220's wifi kill switch. Charger comes with both US and EU prongs. software impressions it's manjaro :( it's KDE :( it comes with mpv :) bluez instead of bluetoothd :( firewalld instead of UFW WiFi dongle. To get around no RJ45 port, I use a USB->RJ45 adapter. I have an ASIX ax88772 dongle (UGREEN branded but I'm not sure that matters). Both of these dongles seem to work with every single operating system and hardware configuration I've tried them with. Arm is strange, so we must boot from an SD card (running any OS, in my case NetBSD) in order to burn an image to the internal storage. From a separate machine, the options passed to dd are important. $ wget https://cdn.netbsd.org/pub/NetBSD/NetBSD-9.3/evbarm-aarch64/binary/gzimg/arm64.img.gz $ wget http://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/x86_64/.9.0_2022Q2_pkgbuild/All/u-boot-pinebook-pro-2022.01nb1.tgz $ gunzip ./arm64.img $ tar xzf ./u-boot-pinebook-pro-2022.01nb1.tgz $ sudo umount /dev/sdx* $ sudo dd if=./arm64.img of=/dev/sdx status=progress conv=fsync bs=1M $ sudo sync $ sudo dd if=./u-boot-pinebook-pro-2022.01nb1/share/u-boot/pinebook-pro/rksd_loader.img of=/dev/sdx seek=64 conv=sync status=progress $ sudo sync $ sudo eject /dev/sdx And, to install NetBSD to the internal EMMC, the process is similar. NetBSD's version of dd varies slightly but the options passed are important. # ftp https://cdn.netbsd.org/pub/NetBSD/NetBSD-9.3/evbarm-aarch64/binary/gzimg/arm64.img.gz # gunzip ./arm64.img # dd if=./arm64.img of=/dev/rl0d conv=sync bs=1m # sync # PKG_PATH="http://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/aarch64/9.3/All/" pkg_add pkgin # pkgin install u-boot-pinebook-pro # sudo dd if=/usr/pkg/share/u-boot/pinebook-pro/rksd_loader.img of=/dev/rld0 seek=64 conv=sync # sync # reboot And, some more desktop centric things after booting from EMMC: # passwd # echo "postfix=NO" >> /etc/rc.conf # echo "xdm=YES" >> /etc/rc.conf Installing pkgin (and some packages): # PKG_PATH="https://cdn.NetBSD.org/pub/pkgsrc/packages/NetBSD/aarch64/9.3/All/" pkg_add pkgin # sed -i'' -e 's/9.0/9.3/g' /usr/pkg/etc/pkgin/repositories.conf # pkgin install vim git mozilla-rootcerts mozilla-rootcerts-openssl The rest is NetBSD specific and I've avoided getting into it here because it doesn't have anything to do with the PBP. Performance The PBP has 6 cores (2 fast, 4 slow) and 4gb ram. The cpu is fairly slow but entirely usable. On large procedural jobs like software compilation, it's painful. For concurrent jobs, it's mostly fine. Compiler performance As expected, the PBP is slower when it comes to compilation than a standard amd64 machine. Surprisingly enough, NetBSD was significantly slower than Manjaro. This is likely due to the Linux kernel knowing how to better handle multiple CPUs with varying speeds. sequential jobs I used plan9port because it's a fairly large but portable project. Compilation is largely sequential, invokes many standard shell utilities, and involves extra preprocessor steps to convert 9 C into something a standard UNIX compiler like GCC or Clang can compile.

Same 8th gen Core i7 (make -j7): real 27.36 user 170.21 sys 11.30 Same 2nd gen Core i5 (make -j7, approaching the exponential decay of marginal returns on concurrent processing): real 77.07 user 292.46 sys 10.00 On the PBP (make -j7) (running stock Manjaro image): real 220.60 user 1145.40 sys 59.90 On the PBP (make -j7) (running NetBSD): real 319.30 user 1560.87 sys 255.33 Web browser testing Because the PBP has similar hardware specifications to the adware subsidized craptops sold by google, I thought it would be a good idea to compare web browser performance on these systems as well. I found a few web browser benchmark tests at browserbench.org. They're probably snakeoil but running JS tests is a good way to put a number on how performant $browser on $hardware is. Scores from the JetStream2 test JetStream 2.1 is a JavaScript and WebAssembly benchmark suite focused on the most advanced web applications. It rewards browsers that start up quickly, execute code quickly, and run smoothly. For more information, read the in-depth analysis. Bigger scores are better. Thinkpad T490 79.555 Thinkpad X220 39.983 PBP (manjaro) 19.148 I don't have an chromesumption book to test against, so all I can say is that the PBP is slower than a workhorse amd64 machine when it comes to interpreting javascript. Conclusion Did the PBP fulfill it's needs? The intended use case was "UNIX machine I can charge from an existing battery or alternator". This immediately invokes ideas of "why would I even need wifi support?" Ultimately, I ended up flashing a bad image to the SPI flash chip and I cannot get the system to boot (or even show signs of life). I have attempted to enter maskrom mode to re-flash the SPI but I am unsuccessful. There are a few other things I need to try. I'll update this if I ever get it functional again. I did not have the opportunity to test the machine in the exact environment I got it for but it was fun before I bricked it. Again, a place for updates. Who is the PBP for? HACKERS! Obviously, the types of people who are interested in pine64 devices and similar SBCs are already computer owners (if not computer hoarders). It's unlikely that the PBP will become my (or anyone's) primary computer but that doesn't mean that it's useless. The entire point of arm SBCs is to have fun so why not have fun? Just don't flash your SPI if you want it to work as expected. Some final thoughts on open hardware Oftentimes, before purchasing freedom centric hardware, I search for a few reviews so that I can set my expectations correctly. Oftentimes these reviews are very epidermal: they're not even skin deep. These reviewers are consumers producing reviews for a consumer audience, not hackers producing in-depth reviews for hacker audience. These types of reviews are frustrating for me but fundamental flaws seem to shine through the lack of thoroughness. I think that the general negative reviews on open hardware largely stem from unrealistic expectations. The community seems to over-hype many of these devices out of ignorance, stating that $freedomDevice is the $proprietaryAlternative killer, the end all be all device that will usher in the year of the Linux $deviceCategory. Oftentimes, it seems like the high expectations fall flat when confronted with the reality of open hardware: it's either way too expensive or way too experimental. It seems like many of these devices are lacking both developer time and users who are both enthusiastic and knowledgeable. Pitfalls of mobile UNIX include bad power management, difficulty hotplugging wireless chipsets, graphical interfaces attempting to cope with the fact that they don't have a physical keyboard, etc. There is still much work to be done. As for users, it seems that the most enthusiastic users always have the impression that $linuxDevice will have 1:1 feature parity with $proprietaryDevice. Maybe it's just that the loudest users are heard or that we only want to hear utopian dreams of a free software future. A prime example of this conflict between expectations and reality: Linux smartphones. It doesn't help when many linux smartphones over the years were advertised as a viable android competitor rather than anything other than what they actually were: an arm board attached to a touch screen and a modem. I oftentimes ask myself "what is open source worth?". How much money are you willing to throw at an idea you like? Surely, money thrown at an idea you like is being used better than money thrown at an idea you don't like. In many cases, it seems like open hardware devices are more expensive than their proprietary counterparts for a few reasons. The two largest reasons are small batch manufacturing and the fact that open hardware isn't subsidized by pre-installed adware (in the case of nearly every device that comes pre-loaded with proprietary software). What is open source worth? A few extra dollars, a few extra hours of configuration, a few extra papercuts, and a clean conscious knowing that I didn't pay for yet another windows license I will never use and will never get a refund for. Open source is worth investing in because the, albeit slow, improvements to open hardware and software have wider implications than just "buying a laptop with Linux pre installed". Future projects something with the raspi NetBSD in depth "why is my lightbulb running android?" and other Internet-Of-Terror ideas turning a router into a general purpose computing device (probably MIPS because where else am I going to find a MIPS CPU? Might as well do something novel instead of $arm-project-1209)

Launched in March, the Experiential Marketing Measurement Coalition (EMMC) is out to standardise core metrics and assessment methodologies and promote them, alongside aggregating and sharing anonymous benchmarks. In this episode, EMMC founders Dax Callner, strategy director at Smyle, Katie Streten, head of experiential strategy for VMLY&R Commerce and Matt Sincaglia, VP of strategy & analytics at RedPeg Marketing, talk about the inspiration they drew from the lack of certified approaches to measurement in “our space” and the subsequent thinking and planning behind the coalition. They discuss measuring what matters, bypassing the competitive instinct to deliver telling detail for the whole membership, which includes the likes of Astound, DRP, Explori, George P Johnson, Impact and Velocity, presenting understandable core metrics and the ‘So What’ test.

It’s a totally free marketplace that simplifies the buying and selling process, and help you learn about EVs along the way too. KIA CV PROTOTYPE SPOTTED AT FAST CHARGING: 175 KW AT 43% SOC "A camouflaged Kia CV prototype was recently seen at an IONITY fast-charging station, charging at a really high rate. According to the image, posted by Hank Scribner, the car was charging at 174 kW (569 V and 306 A) at 43% of State of Charge (SOC). Over the previous six minutes, the car received 15.562 kWh, which translate to an average of almost 156 kW." says InsideEVs: "Anyway, the 800 V batteries in the new cars from Hyundai Motor Group (Hyundai, Kia and Genesis) should be really strong in terms of charging rate. Kia said that replenishing 100 km (62 miles) of range will take as little as 4 minutes (of course at optimum conditions and with a proper DC fast charger)." https://insideevs.com/news/492429/kia-cv-prototype-spotted-fast-charging-175kw/?utm_source=RSS&utm_medium=referral&utm_campaign=RSS-all-articles VOLKSWAGEN ID.3 TOUR 5 HAS 5-SEATS DESPITE ITS 82 KWH BATTERY "Volkswagen has introduced a new version of the ID.3 model, called Tour 5, which surprised us a little bit because it has 5-seats and an 82 kWh battery - a combination that did not exist previously. When the German manufacturer first announced the ID.3 and its three battery options (48 kWh, 58 kWh and 82 kWh), it turned out that only the two first would be 5-seaters. The larger battery version was a 4-seater (without panoramic roof option), reportedly because of the weight limitation." says InsideEVs: "It was not good news for the all-electric compact, but now it seems that the issue was somehow solved, as the German configurator offers a 5-seat, 82 kWh battery version (77 kW usable). Three ID.3 (82 kWh) versions are offered, but only one with five seats. We have no idea how the problem was solved (if the weight was the limitation) - it could be anything from higher energy-dense cells, through a slimming treatment or removal of the most weight-intense options for this version." https://insideevs.com/news/492441/volkswagen-id3-tour-5-seats/?utm_source=RSS&utm_medium=referral&utm_campaign=RSS-all-articles KIA E-NIRO TOPS THE UK’S EV SALES CHARTS Kia e-Niro tops the UK’s EV sales charts for the second consecutive month, with 757 units sold Kia accounts for almost one in five EVs sold in the UK year-to-date The Niro model family was the brand’s best-seller in February. With 1,215 units sold across all three variants (including e-Niro, Self-Charging Hybrid and Plug-in Hybrid variants), the Niro family was the sixth best-selling model in the UK in February, with the fully electric e-Niro accounting for 757 of these sales. Combined with sales of the Soul EV (41 units in February, 105 units year-to-date), Kia BEVs account for almost one in five (19 per cent) of all fully electric vehicles sold in the UK so far this year. OCTOPUS ENERGY JOINS UP WITH IONITY "UK energy supplier and charging network operator Octopus Energy has signed a roaming agreement with Ionity. Ionity’s HPC chargers in the UK and mainland Europe will be now be connected to Octopus Energy’s Electric Juice Network (EJN)." repotrs electrive: "Octopus Energy says that Electric Juice Network users will receive a five per cent discount when charging at Ionity stations. At Ionity’s standard price of £0.69/kWh, that would be £0.65/kWh." https://www.electrive.com/2021/03/05/octopus-energy-joins-up-with-ionity/ TESLA LAUNCHES NEW SOCIAL MEDIA PLATFORM TO ‘ENGAGE’ ITS COMMUNITY "Tesla is launching today a new social media platform called “Engage Tesla” to serve as a “home base” for owners’ clubs and Tesla’s policy team. The automaker will also be discontinuing its forum." according to electrek: "Tesla writes in the description: “Starting March 15th, Tesla Forums will become read only. To continue the conversation with the Tesla community visit engage.tesla.com.”. Engage Tesla is a new platform for both Tesla’s public policy team and Tesla Owner’s Clubs. Its goal is to create a digital home base for all of our work, and make it easier for Tesla community members to learn what’s top of mind for us, take meaningful action, and stay in the loop. We hope you’ll join us in getting involved.”" https://electrek.co/2021/03/05/tesla-launches-new-social-media-platform-engage-community-promote-policies/ TESLA NOW ACCEPTING REIMBURSEMENT REQUESTS FOR EMMC REPLACEMENTS "Late last year Tesla announced it would begin offering Model S and Model X owners free replacements of their eMMC (embedded MultiMediaCard). The memory chips were included in vehicles built prior to 2018 and would eventually fail as it was too small for its intended purpose." according to Drive Tesla Canada "Fortunately owners who had already paid out of pocket for the replacement were told at the same time they may be eligible for reimbursements, and more information would come in February. They were a few days late, but Tesla has now launched a new form online for those owners to submit their information to request a refund. Tesla says to log in to your Tesla account where if you are eligible you will find the claim form." https://driveteslacanada.ca/model-s/tesla-now-accepting-reimbursement-requests-for-emmc-replacements/?utm_source=rss&utm_medium=rss&utm_campaign=tesla-now-accepting-reimbursement-requests-for-emmc-replacements FEDEX DELIVERY TRUCKS TO BE ALL ZERO-EMISSIONS ""FedEx has announced that its fleet of pickup and delivery trucks will be all-EV by 2040. The move to an all-electric fleet is part of the package-delivery company's goal to be carbon-neutral by 2040." according to Autoblog: "FedEx operates a fleet of some 200,000 pickup and delivery trucks. The company says it will spend $2 billion to achieve its goal of carbon-neutrality, which in addition to an electrified truck fleet will also involve reducing the fuel demand for its planes." https://www.autoblog.com/2021/03/05/fedex-trucks-all-ev-2040/ VW TO BUILD A ‘HIGH RANGE’ AND ‘SHORT CHARGING TIME’ EV FOR 2026 "Volkswagen is going all in on electric vehicles, and at an event detailing its even more aggressive future plans, the German automaker said that it has an electric sedan planned with a 2026 launch, dubbed Project Trinity. VW says that the Trinity sedan will set "new standards" with its charging speed, battery range, and in other technology." repoerts Car & Driver: "VW released a sketch of the Trinity, showing a sweeping roofline that resembles that of the Audi A7. In January, German newspaper Welt reported that the new sedan will have a starting price of around $42,000, which would make it slightly more expensive than the Tesla Model 3." https://www.caranddriver.com/news/a35741685/vw-to-build-ev-trinity-2026/ You can listen to all 1011 previous episodes of this this for free, where you get your podcasts from, plus the blog https://www.evnewsdaily.com/ – remember to subscribe, which means you don’t have to think about downloading the show each day, plus you get it first and free and automatically.

Dieser Chip wird durch das Schreiben von temporären Dateien massiv belastet und die Schreibleistung sinkt mit dem Alter. Mittlerweile hat Tesla einen #Garantie-Austausch dieses Chips auch bei Ausfall nach der 4 Jahre-Regelgarantie versprochen. Kann so eine gebremste MCU1 mit einem neuen AP3-Board funktionieren? Ich versuche mich in Rückschlüssen aus meinen Erfahrungen in Sachen Maschinensteuerung auf die Tesla-Computer und Netzwerke.
Hackaday editors Elliot Williams and Mike Szczys recount the coolest hacks from the past week. Most clocks keep time with a quartz crystal, but we discuss one that uses a tuning fork... like the kind you use to tune a piano. Ghidra is a powerful reverse engineering tool developed by the NSA that was recently put to good use changing an embedded thermometer display from Celsius to Fahrenheit. We talk turkey on the Texas power grid problems and Tesla's eMMC failures. And of course there's some room for nostalgia as we walk down memory lane with the BASIC programming language.

Microsoft prepara un parche para un curioso bug de una sola línea que puede camuflarse dentro de casi cualquier archivo, incluso sin abrirlo, y puede corromper en parte o totalmente el almacenamiento interno. Funciona haciendo que Windows busque el icono correspondiente al archivo, pero no puede y acaba corrompiendo la tabla de ficheros NTFS. India y Turquía pondrán a prueba las políticas de WhatsApp. La junta de competencia de Turquía y la Corte Superior de Delhi revisarán si los cambios recientes de privacidad en WhatsApp incumplen las respectivas leyes nacionales. EE.UU. añade Xiaomi a una lista negra "secundaria". Una orden presidencial de última hora, impedirá a empresas estadounidenses invertir en la firma china a partir de noviembre de 2021 tras asociarla con el ejército chino. Podrá seguir usando Android, etc. Hay dos listas diferentes. La más famosa está gestionada por el Ministerio de Comercio, y es donde están Huawei, DJI, etc. pero no Xiaomi. Las acciones cayeron un 10% igualmente. Xiaomi entrará en una segunda lista que depende de Defensa, donde también está Huawei, pero no es la que impide la comercialización normal, solo las inversiones. Samsung presenta los Galaxy S21 en tres modelos diferentes. Normal, Plus y Ultra que llegarán el 29 de enero por precios desde 859 hasta 1.439 euros. Las pruebas iniciales dan una muy buena primera impresión, pero les costará destacar. — También sin cargador. Vienen de la mano de unas etiquetas inteligentes con Bluetooth que costarán 35 euros cada una. Lidl vende sus propios auriculares inalámbricos por 20 euros. Dentro de su marca Silvercrest, cuentan con un diseño y prestaciones muy similares a los AirPods, aunque de color negro. Vienen incluso con carga inalámbrica en la cajita. Están agotados online. LG pone a la venta una mascarilla electrónica por 150 euros. Pesa 126 gramos en total, cuenta con una batería, un sistema de ventilación activo y unos filtros desechables que se deben cambiar cada siete y 30 días respectivamente. Nike denuncia a cientos de webs e influencers. En total unos 1.000 cargos diferentes a empresas e individuales que operan tiendas con productos falsificados de la marca, principalmente calzado deportivo. De momento los acusados permanecen bajo sello. Cisco se niega a parchear unas vulnerabilidades graves que afectan a varios routers y cortafuegos destinados a individuales y pequeños negocios porque había pasado la fecha límite de mantenimiento... hace solo un mes. Multa a Caixabank por la gestión de datos personales. El banco español tendrá que pagar 6 millones de euros en una pareja de multas por irregularidades en varios puntos en el alta, baja y cesión de datos de los clientes. — La mayor multa por RGPD en España. Disney se apunta a los estrenos simultáneos y gratuitos digitales. Ha estrenado películas de pago en Internet + cine, luego otras solo en Disney+ pero sin coste adicional, y ahora prueba el último formato que le queda: estrenar en el cine y sin coste extra en streaming. EE.UU. obligará a Tesla a reparar todos los Model S y X viejos. Los modelos vendidos desde el 2012, en su lanzamiento, hasta 2018, contenían unas memorias eMMC que se van degradando en capacidad con el tiempo. Unos 158.000 coches. Este tipo de problemas serán cada vez más comunes a medida que los coches se computizan. Tras años de quejas, Tesla abrió hace unas semanas un programa de recambios, ahora las autoridades le obligarían a hacerlo de forma completa. TCL presenta una tableta con pantalla de tinta electrónica de color. Se llama NXTPAPER, costará 350 euros, y en vez de LCD tendrá una pantalla de tinta electrónica de nueva generación que permite mostrar colores, mucho menor consumo y un refresco relativamente rápido (vídeo).

Show #830 Good morning, good afternoon and good evening wherever you are in the world, welcome to EV News Daily for Sunday 5th July 2020. It’s Martyn Lee here and I go through every EV story so you don't have to. Thank you to MYEV.com for helping make this show, they’ve built the first marketplace specifically for Electric Vehicles. It’s a totally free marketplace that simplifies the buying and selling process, and help you learn about EVs along the way too. IONITY CELEBRATES 250TH FAST-CHARGING STATION IN EUROPE "IONITY, the European fast-charging network, founded in 2017 by BMW Group, Daimler AG, Ford Motor Company and the Volkswagen Group with Porsche AG, and joined by Hyundai Motor Group (Hyundai and Kia) in 2019, celebrates its 250th charging location." says InsideEVs: "The company announced the news on July 3, 2020, about six months since the milestone of 200 stations. The pace of new installations was probably significantly lowered by the COVID-19 lockdown, so we are wondering whether the target of 400 locations by the end of 2020 is still the case. IONITY's website shows that there are 251 stations installed, while another 49 are under construction. Most of the chargers are supplied by Tritium (55%: 569 chargers at 139 stations), followed by ABB (41%: 424 chargers at 108 stations) plus 5 stations with a total of 28 Porsche Engineering chargers." https://insideevs.com/news/432240/ionity-250-fast-charging-station-europe/ TESLA INSTALLS 500TH SUPERCHARGER IN UK & IRELAND "Tesla continues to expand its electric vehicle charging network around the world, following the announcement of its CEO Elon Musk. To meet growing demand, 500 Supercharger devices have now been installed in the UK and Ireland. The first Superchargers appeared in the UK in 2014 and are now available in 63 locations. Tesla has already installed 42 new Superchargers this year, which confirms the company's intention to expand globally." reports Tesmanian: "Previously, the company’s Supercharger Network expansion has slowed down to allow for the ramp in the production of Supercharger V3 units. V3 Supercharging uses the same principle as Tesla’s current Superchargers but adds a 1MW power cabinet to the equation. That means 250kW peak charging rates per car. To date, eight V3 Superchargers have been installed in the UK - all at the brand’s Park Royal service center in London. Model 3 is compatible with the device as standard, and models S and X come with an adapter that allows them to use the same system." https://www.tesmanian.com/blogs/tesmanian-blog/tesla-installs-500th-supercharger-in-uk-ireland TESLA UPDATES WARRANTY ON PROBLEMATIC MEDIA UNIT AND TOUCHSCREEN "Tesla has updated its warranty for its already problematic media unit and touchscreen with a ridiculously shorter two-year or 25,000-mile limit." is the wording of electrek today: "As we previously reported, Tesla had a problem with the embedded Multi-Media-Card memory (eMMC) in its original MCU (the central media unit with a touchscreen). It is being overwritten to the point of failure, and many early Tesla owners are having to replace it. This week, Tesla updated the warranty on replacement MCUs and slashed the length of coverage in half." https://electrek.co/2020/07/04/tesla-updates-warranty-problema BUICK TO INTRODUCE VELITE 6 PHEV IN CHINATIC-MEDIA-UNIT-TOUCHSCREEN/ "Buick is adding the VELITE 6 plug-in hybrid electric vehicle (PHEV) to its new energy vehicle (NEV) portfolio in China. The model is expected to be launched this month. The VELITE 6 PHEV will be powered by Buick eMotion electric drive technology that leverages GM’s global electrification expertise." reports Green Car Congress. And don't get that confused with the Buick Velite 7 I've previously reported on: "Based on a variant of the BEV2 platform that the Chevrolet Bolt EV debuted in 2016, the brand-new Buick Velite 7 EV includes a state-of-the-art battery pack that will allow it to offer an electric range of up to 500 kilometers – equivalent to about 311 miles – with a full charge, calculated under the conditions of the New European Driving Cycle (NEDC). In China, this makes it the most efficient electric crossover in its class. Aesthetically, the Velite 7 EV boasts a relatively simple design with a distinctive front fascia, and might share a few body panels with the upcoming Chevrolet Bolt EUV. The company has announced that the new high-performance lithium-ion modular battery that mounts the new Buick Velite 7 has a higher energy density, thanks to improved cell chemistry. Additionally, the battery pack has an advanced structural design and BMS thermal management system that meets GM’s global standards" as per GM Authority https://www.greencarcongress.com/2020/07/20200704-buick.html https://gmauthority.com/blog/2020/06/brand-new-buick-velite-7-ev-crossover-unveiled-in-china/ TESLA SUPERCHARGING USAGE HITS PRE-COVID 19 HIGHS @elonmusk: "North American Supercharger usage is now at pre-covid high, Europe about a week behind, China & Asia-Pacific in general doing great" TEPCO TO REUSE CHINESE EV BATTERIES FOR ENERGY STORAGE "Japanese utility Tokyo Electric Power Co. Holdings will launch a storage battery business utilizing used electric-vehicle batteries from China, Nikkei has learned. The plan is to assemble used batteries into a containerized energy storage system to assist renewable-energy plants" writes Nikkei Asian Review: "Transmission and distribution unit Tepco Power Grid will purchase used EV batteries from trading companies in China and elsewhere, combining 20 to 30 vehicles' worth of them into a container-type battery. The batteries will then be sold to solar and other renewable-energy plants for 30% to 50% less than new batteries. Tepco hopes to grow the business into a new revenue stream. EV batteries are generally replaced after seven to 10 years, but the used batteries still have about 70% of their original capacity" https://asia.nikkei.com/Business/Energy/Tepco-to-reuse-Chinese-EV-batteries-for-energy-storage AUDI, ENBW TO TURN ELECTRIC CAR BATTERIES INTO GRID SUPPORT TOOLS "Audi and utility EnBW are setting up an electric car battery operation at EnBW's Heilbronn plant to build scaleable storage facilities by the end of this year, drawing on retired batteries to help power grids." according to Car and Bike.com: "Electric vehicle battery recycling and reuse has become a priority for car and battery makers while renewable energy companies face the problem of how to absorb surpluses of wind and solar power to avoid waste and disruption to the stability of grids, slowing the transition to purely carbon-free energy system. Audi has been testing the behaviour of electric car batteries, which represent a third of an EV's unit costs, in a research setting in Berlin for three years. The batteries to be used for the commercial phase of the project come from test cars, which have run hundreds of thousands of kilometres, Kupfer said. "A used EV battery still can function for another three to 10 years," he said." https://www.carandbike.com/news/audi-enbw-to-turn-electric-car-batteries-into-grid-support-tools-2257009 ELECTRIC CAR SCRAPPAGE SCHEME REJECTED BY GOVERNMENT MINISTERS "Hopes of a new scrappage scheme reportedly offering up to £6,000 towards the cost of an electric car have been dashed now that the government appears to have rejected the idea." says the RAC: "The Times reports that a letter from Rachel Maclean, junior minister for transport and the environment, reads: “the government has no plans at this stage to introduce a scrappage scheme.” A similar scrappage scheme was dismissed in 2018 as ministers believed it was “difficult to deliver [and] potentially open to abuse.” At present, the government provides a grant of up to £3,000 only towards the purchase of plug-in cars, although this was cut by £500 in March." https://www.rac.co.uk/drive/news/motoring-news/electric-car-scrappage-scheme-rejected-by-government-ministers/ [mention for Premium Partners] You can listen to all 829 previous episodes of this this for free, where you get your podcasts from, plus the blog https://www.evnewsdaily.com/ – remember to subscribe, which means you don’t have to think about downloading the show each day, plus you get it first and free and automatically.

In this episode I speak with author and physician Dr. Lewis Mehl-Madrona about how he brings storytelling and narrative into his healing processes. A teacher in many respects, Lewis believes that telling a story (or “sharing a case-study” in doctor talk), is the most effective way to teach. This conversation is helpful in shifting the way you look at your life and the stories you tell yourself that not only affect your neurological and mental health, but your physical health as well. What are the biological consequences of the stories that we tell ourselves? Can we rewrite our stories to better our lives? “We are the swarm of stories that surround our physical body.” - Lewis Mehl-Madrona Topics we cover include: Indiginous knowledge Narrative medicine The Power of Talking Circles Imagery & Narrative in Healing Issues of Psychology during Birthing Epigenetics vs. genetics in disease About our guest: Lewis Mehl-Madrona, MD, graduated from Stanford University School of Medicine and trained in family medicine, psychiatry, and clinical psychology. He has been on the faculties of several medical schools, most recently as associate professor of family medicine at the University of New England. He is the author of Coyote Medicine, Coyote Healing, and Coyote Wisdom, a trilogy of books on what Native culture has to offer the modern world. He has also written Narrative Medicine, Healing the Mind through the Power of Story: the Promise of Narrative Psychiatry, and, his most recent book with Barbara Mainguy, Remapping Your Mind: the Neuroscience of Self-Transformation through Story. Lewis currently teaches with the family medicine residency at Eastern Maine Medical Center (EMMC) in Bangor, where he does inpatient medicine, outpatient precepting, and obstetrics. He works in consultation-liaison psychiatry at EMMC and also at Acadia Hospital. He serves on the Board of Directors of the Coyote Institute for Studies of Change and Transformation. Lewis has been studying traditional healing and healers since his early days and has written about their work and the process of healing.

Hackaday Editors Mike Szczys and Elliot Williams shed some light on a true week of hacks. It seems like all kinds of projects are doing this the "wrong" way this week and its delightful to see what they learn along the way. Hovercrafts can work using the coanda effect which uses the blowers on the outside. You can dump your Linux logs to soldered-on eMMC memory, and chain sprockets can be cut from construction brackets. If you really want to build your own rebreather you can. All of these hacks work, and seeing how to do something differently is an inspiring tribute to the art of hardware hacking... you can learn a lot by asking yourself why these particular techniques are not the most commonly used. Plus, Mike caught up with Alessandro Ranellucci at Maker Faire Rome last weekend. In addition to being the original author of slic3r, Alessandro has been Italy's Open Source lead for the last several years. He talks about the legislation that was passed earlier this year mandating that software commissioned by the government must now be Open Source and released with an open license.

FreeBSD 10.4-RELEASE is here, more EuroBSDcon travel notes, the KRACK attack, ZFS and DTrace on NetBSD, and pfsense 2.4. This episode was brought to you by Headlines FreeBSD 10.4-RELEASE Available (https://www.freebsd.org/releases/10.4R/announce.html) FreeBSD 10.4-RELEASE is out. The FreeBSD Project dedicates the FreeBSD 10.4-RELEASE to the memory of Andrey A. Chernov. Some of the highlights: 10.4-RELEASE is the first FreeBSD release to feature full support for eMMC storage, including eMMC partitions, TRIM and bus speed modes up to HS400. Please note, though, that availability of especially the DDR52, HS200 and HS400 modes requires support in the actual sdhci(4) front-end as well as by the hardware used. Also note, that the SDHCI controller part of Intel® Apollo Lake chipsets is affected by several severe silicon bugs. Apparently, it depends on the particular Apollo Lake platform whether the workarounds in place so far are sufficient to avoid timeouts on attaching sdhci(4) there. Also in case a GPT disk label is used, the fsckffs(8) utility now is able to find alternate superblocks. The aesni(4) driver now no longer shares a single FPU context across multiple sessions in multiple threads, addressing problems seen when employing aesni(4) for accelerating ipsec(4). Support for the Kaby Lake generation of Intel® i219(4)/ i219(5) devices has been added to the em(4) driver. The em(4) driver is now capable of enabling Wake On LAN (WOL) also for Intel® i217, i218 and i219 chips. Note that stale interface configurations from previous unsuccessful attempts to enable WOL for these devices now will actually take effect. For example, an ifconfig em0 wol activates all WOL variants including wolmcast, which might be undesirable. Support for WOL has been added to the igb(4) driver, which was not able to activate this feature on any device before. The same remark regarding stale WOL configurations as for the em(4) driver applies. Userland coredumps can now trigger events such as generating a human readable crash report via devd(8). This feature is off by default. The firmware shipping with the qlxgbe(4) driver has been updated to version 5.4.66. Additionally, this driver has received some TSO and locking fixes, performance optimizations as well as SYSCTLs providing MAC, RX and TX statistics. Mellanox® ConnectX-4 series adapters are now supported by the newly added mlx5ib(4) driver. OpenSSH received an update to version 7.3p1. GNOME has been updated to version 3.18. Xorg-Server has been updated to version 1.18.4. Check out the full release notes and upgrade your systems to 10.4-RELEASE. Thanks to the FreeBSD Release Engineering Team for their efforts. *** EuroBSDcon 2017: "travel notes" after the conference (https://blog.netbsd.org/tnf/entry/eurobsdcon_2017_travel_notes_after) Leonardo Taccari posted in the NetBSD blog about his experiences at EuroBSDcon 2017: Let me tell you about my experience at EuroBSDcon 2017 in Paris, France. We will see what was presented during the NetBSD developer summit on Friday and then we will give a look to all of the NetBSD and pkgsrc presentations given during the conference session on Saturday and Sunday. Of course, a lot of fun also happened on the "hall track", the several breaks during the conference and the dinners we had together with other *BSD developers and community! This is difficult to describe and I will try to just share some part of that with photographs that we have taken. I can just say that it was a really beautiful experience, I had a great time with others and, after coming back home... ...I miss all of that! :) So, if you have never been in any BSD conferences I strongly suggest you to go to the next ones, so please stay tuned via NetBSD Events. Being there this is probably the only way to understand these feelings! Thursday (21/09): NetBSD developers dinner Arriving in Paris via a night train from Italy I literally sleep-walked through Paris getting lost again and again. After getting in touch with other developers we had a dinner together and went sightseeing for a^Wseveral beers! Friday (22/09): NetBSD developers summit On Friday morning we met for the NetBSD developers summit kindly hosted by Arolla. NetBSD on Google Compute Engine -- Benny Siegert (bsiegert) Scripting DDB with Forth -- Valery Ushakov (uwe) News from the version control front -- Jörg Sonnenberger (joerg) Afternoon discussions and dinner After the lunch we had several non-scheduled discussions, some time for hacking, etc. We then had a nice dinner together (it was in a restaurant with a very nice waiter who always shouted after every order or after accidentally dropping and crashing dishes!, yeah! That's probably a bit weird but I liked that attitude! :)) and then did some sightseeing and had a beer together. Saturday (23/09): First day of conference session and Social Event A Modern Replacement for BSD spell(1) -- Abhinav Upadhyay (abhinav) Portable Hotplugging: NetBSD's uvm_hotplug(9) API development -- Cherry G. Mathew (cherry) Hardening pkgsrc -- Pierre Pronchery (khorben) Reproducible builds on NetBSD -- Christos Zoulas (christos) Social event The social event on Saturday evening took place on a boat that cruised on the Seine river. It was a very nice and different way to sightsee Paris, eat and enjoy some drinks and socialize and discuss with other developers and community. + Sunday (24/09): Second day of conference session The school of hard knocks - PT1 -- Sevan Janiyan (sevan) The LLDB Debugger on NetBSD -- Kamil Rytarowski (kamil) What's in store for NetBSD 8.0? -- Alistair Crooks (agc) Sunday dinner After the conference we did some sightseeing in Paris, had a dinner together and then enjoyed some beers! Conclusion It was a very nice weekend and conference. It is worth to mention that EuroBSDcon 2017 was the biggest BSD conference (more than 300 people attended it!). I would like to thank the entire EuroBSDcon organising committee (Baptiste Daroussin, Antoine Jacoutot, Jean-Sébastien Pédron and Jean-Yves Migeon), EuroBSDcon programme committee (Antoine Jacoutot, Lars Engels, Ollivier Robert, Sevan Janiyan, Jörg Sonnenberger, Jasper Lievisse Adriaanse and Janne Johansson) and EuroBSDcon Foundation for organizing such a wonderful conference! I also would like to thank the speakers for presenting very interesting talks, all developers and community that attended the NetBSD devsummit and conference, in particular Jean-Yves and Jörg, for organizing and moderating the devsummit and Arolla that kindly hosted us for the NetBSD devsummit! A special thanks also to Abhinav (abhinav) and Martin (martin) for photographs and locals Jean-Yves (jym) and Stoned (seb) for helping us in not get lost in Paris' rues! :) Thank you! *** WiFi Vulnerability in WPA2: KRACK (https://www.krackattacks.com/) “We discovered serious weaknesses in WPA2, a protocol that secures all modern protected Wi-Fi networks. An attacker within range of a victim can exploit these weaknesses using key reinstallation attacks (KRACKs). Concretely, attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted. This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on. The attack works against all modern protected Wi-Fi networks. Depending on the network configuration, it is also possible to inject and manipulate data. For example, an attacker might be able to inject ransomware or other malware into websites.” “Note that if your device supports Wi-Fi, it is most likely affected. During our initial research, we discovered ourselves that Android, Linux, Apple, Windows, OpenBSD, MediaTek, Linksys, and others, are all affected by some variant of the attacks. For more information about specific products, consult the database of CERT/CC, or contact your vendor.” FreeBSD Advisory (https://www.freebsd.org/security/advisories/FreeBSD-SA-17:07.wpa.asc) As of the date of this recording, a few weeks ahead of when this episode will air, the issue is fixed in FreeBSD 11.0 and 11.1, and a workaround has been provided for 10.3 and 10.4 (install newer wpa_supplicant from ports). A fix for 10.3 and 10.4 is expected soon. They will more than likely be out by time you are watching this. The fix for 10.3 and 10.4 is more complicated because the version of wpasupplicant included in the base system is 2.0, from January 2013, so is nearly 5 years old, so the patches do not apply cleanly. The security team is still considering if it will try to patch 2.0, or just replace the version of wpasupplicant with 2.5 from FreeBSD 11.x. OpenBSD was unwilling to wait when the embargo was extended on this vulnerability and stealth fixed the issue on Aug 30th (https://marc.info/?l=openbsd-cvs&m=150410571407760&w=2) stsp@openbsd.org ‘s Mastodon post (https://mastodon.social/@stsp/98837563531323569) Lobste.rs conversation about flaw and OpenBSD's reaction (https://lobste.rs/s/dwzplh/krack_attacks_breaking_wpa2#c_pbhnfz) “What happened is that he told me on July 15, and gave a 6 weeks embargo until end of August. We already complained back then that this was way too long and leaving people exposed. Then he got CERT (and, thus, US gov agencies) involved and had to extend the embargo even further until today. At that point we already had the ball rolling and decided to stick to the original agreement with him, and he gave us an agreeing nod towards that as well.” “In this situation, a request for keeping the problem and fix secret is a request to leave our users at risk and exposed to insiders who will potentially use the bug to exploit our users. And we have no idea who the other insiders are. We have to assume that information of this kind leaks and dissipates pretty fast in the security “community”.” “We chose to serve the needs of our users who are the vulnerable people in this drama. I stand by that choice.” As a result of this: “To avoid this problem in the future, OpenBSD will now receive vulnerability notifications closer to the end of an embargo.” NetBSD: “patches for the WPA issues in KRACK Attacks were committed Oct 16th to HEAD & are pending pullup to 6/7/8 branches” (http://mail-index.netbsd.org/source-changes/2017/10/16/msg088877.html) As of this recording, Dragonfly appears to use wpa_supplicant 2.1 which they imported in 2014 and has not been touched in over a year (https://github.com/DragonFlyBSD/DragonFlyBSD/commits/master/contrib/wpa_supplicant) *** News Roundup NetBSD - dtrace and ZFS update (https://mail-index.netbsd.org/tech-kern/2017/10/13/msg022436.html) Chuck Silvers writes to the tech-kern mailing list of NetBSD: I've been working on updating netbsd's copy of the dtrace and zfs code to rebase from the existing ancient opensolaris version to a recent freebsd version. most of the freebsd changes are pretty close to what netbsd needs, so that seems like a more useful upstream for us. I have things working well enough now that I want to share the code in preparation for committing. this update improves upon our existing dtrace/zfs code in several ways: picks up all the upstream zfs fixes and enhancements from the last decade zfs now supports mmap on netbsd, so you can run executables stored in zfs dtrace fbt probes can now be used in kernel modules (such as zfs) A patch is provided here: http://ftp.netbsd.org/pub/NetBSD/misc/chs/diff.cddl.20171012 which needs to be applied using “patch -E” as it adds and removes files. He provides the following summary for the diff: freebsd's dtrace/zfs code as of r315983 (2017-03-26), adapted for netbsd. a few updates to our copy of freebsd's libproc. build system support for using -fno-omit-frame-pointer everywhere and disabling other compiler optimizations that confuse dtrace. sample kernel config changes for a couple evbarm configs (the ones I tested). module/ksyms enhancements for dtrace integration. genfs API enhancements to support zfs. an option to have mutexes not become no-ops during a panic. uvm_aobj API change to support 64-bit aobj sizes (eg. for tmpfs). Known issues with the patch include: unloading the zfs module fails even with no zpools imported if you've done much with zfs since it was loaded. there's some refcounting problem that I haven't tracked down yet. the module refcounting for active fbt probes is bogus. currently module refcounting is protected by kernconfig_lock(), but taking that lock down in the bowels of dtrace seems likely to create deadlocks. I plan to do something fancier but haven't gotten to it yet. the dtrace uregs[] stuff is probably still wrong. the CTF typeid overflow problem is still there (more on this below). Unsupported features include: the ".zfs" virtual directory, eg. ".zfs/snapshot/foo@bar" zvols ZFS ACLs (aka. NFSv4 ACLs) NFS exporting a ZFS file system setting dtrace probes in application code using ZFS as the root fs new crypto hashes SHA512_256, skein, and edonr (the last one is not in freebsd yet either) zio delay injection (used for testing zfs) dtrace support for platforms other than x86 and arm A more detailed description of the CTF typeid overflow is also provided. Check out the full thread with followups and try out the patch if you're on NetBSD. *** pfSense 2.4.0-RELEASE Now Available! (https://www.netgate.com/blog/pfsense-2-4-0-release-now-available.html) Jim Pingle writes about the new release: We are excited to announce the release of pfSense® software version 2.4, now available for new installations and upgrades! pfSense software version 2.4.0 was a herculean effort! It is the culmination of 18 months of hard work by Netgate and community contributors, with over 290 items resolved. According to git, 671 files were changed with a total 1651680 lines added, and 185727 lines deleted. Most of those added lines are from translated strings for multiple language support! + Highlights FreeBSD 11.1-RELEASE as the base Operating System New pfSense installer based on bsdinstall, with support for ZFS, UEFI, and multiple types of partition layouts (e.g. GPT, BIOS) Support for Netgate ARM devices such as the SG-1000 OpenVPN 2.4.x support, which brings features like AES-GCM ciphers, speed improvements, Negotiable Crypto Parameters (NCP), TLS encryption, and dual stack/multihome Translation of the GUI into 13 different languages! For more information on contributing to the translation effort, read our previous blog post and visit the project on Zanata WebGUI improvements, such as a new login page, improved GET/POST CSRF handling, significant improvements to the Dashboard and its AJAX handling Certificate Management improvements including CSR signing and international character support Captive Portal has been rewritten to work without multiple instances of ipfw Important Information: 32-bit x86 and NanoBSD have been deprecated and are not supported on pfSense 2.4. Read the full release notes and let them know how you like the new release. *** OpenBSD changes of note 629 (https://www.tedunangst.com/flak/post/openbsd-changes-of-note-629) Use getrusage to measure CPU time in md5 benchmarking. Add guard pages at the end of kernel stacks so overflows don't run into important stuff. This would be useful in FreeBSD, even just to detect the condition. I had all kinds of strange crashes when I was accidently overflowing the stack when working on the initial version of the ZSTD patches before ZSTD gained a working heap mode. Add dwxe driver for ethernet found on Allwinner A64, H3 and H5 SoCs. Fix a regression caused by removal of SIGIO from some devices. In malloc, always delay freeing chunks and change ‘F' option to perform a more extensive check for double free. Change sendsyslog prototype to take a string, since there's little point logging not strings. The config program tries to modify zero initialized variables. Previous versions of gcc were patched to place these in the data segment, instead of the bss, but clang has no such patches. Long long ago, this was the default behavior for compilers, which is why gcc was patched to maintain that existing behavior, but now we want a slightly less unusual toolchain. Fix the underlying issue for now by annotating such variables with a data section attribute. *** t2k17 Hackathon Report: Philip Guenther: locking and libc (https://undeadly.org/cgi?action=article;sid=20170824080132) Next up in our series of t2k17 hackathon reports is this one from Philip Guenther: I showed up at t2k17 with a couple hold-over diffs from e2k17 that weren't stable then and hadn't gotten much better since, so after a red-eye through Chicago I arrived in the hackroom, fired up my laptop and synced trees. Meanwhile, people trickled in and the best part of hackathons, the conversations and "what do you think about this?" chats started. Theo introduced me to Todd Mortimer (mortimer@), who's been hacking on clang to implement RETGUARD for C programs. Over the hackathon we discussed a few loose ends that cropped up and what the correct behavior should be for them as well as the mechanics of avoiding 0xc3 bytes (the RET opcode) embedded in the middle of other multi-byte x86 machine code. Fun stuff. Martin (mpi@) and I had a conversation about the desirability of being able to sleep while holding netlock and pretty much came down on "oof, the scheduler does need work before the underlying issue driving this question can be resolved enough to answer it". :-( After some final hammering I got in an enhancement to pool(9) to let a pool use (sleeping) rwlocks instead of (spinning) mutexes and then immediately used that for the per-CPU pool cache pool as well as the futex pool. Further pools are likely to be converted as well kernel upper-level locking changes are made. Speaking of, a larger diff I had been working on for said upper-level locking was still suffering deadlock issues so I took a stab at narrowing it down to just a lock for the process tree, mostly mirroring the FreeBSD proctreelock. That appears to be holding up much better and I just have some code arrangement issues around sysptrace() before that'll go out for final review. Then most of the way through the week, Bob (beck@) vocally complained that life would be easier for libressl if we had some version of pthread_once() and the pthread mutex routines in libc. This would make some other stuff easier too (c.f. /usr/X11R6/lib/libpthread-stubs.*) and the TIB work over the last couple years has basically eliminated the runtime costs of doing so, so I spent most the rest of the hackathon finding the right place to draw a line through libpthread and move everything on the one side of the line into libc. That code seems pretty stable and the xenocara and ports people seem to like—or at least accept—the effects, so it will almost certainly go in with the next libc bump. Lots of other random conversations, hacking, meals, and beer. Many thanks to Ken (krw@) and local conspirators for another excellent Toronto hackathon!

Today on BSD Now, the latest Dragonfly BSD release, RaidZ performance, another OpenSSL Vulnerability, and more; all this week on BSD Now. This episode was brought to you by Headlines DragonFly BSD 4.8 is released (https://www.dragonflybsd.org/release48/) Improved kernel performance This release further localizes cache lines and reduces/removes cache ping-ponging on globals. For bulk builds on many-cores or multi-socket systems, we have around a 5% improvement, and certain subsystems such as namecache lookups and exec()s see massive focused improvements. See the corresponding mailing list post with details. Support for eMMC booting, and mobile and high-performance PCIe SSDs This kernel release includes support for eMMC storage as the boot device. We also sport a brand new SMP-friendly, high-performance NVMe SSD driver (PCIe SSD storage). Initial device test results are available. EFI support The installer can now create an EFI or legacy installation. Numerous adjustments have been made to userland utilities and the kernel to support EFI as a mainstream boot environment. The /boot filesystem may now be placed either in its own GPT slice, or in a DragonFly disklabel inside a GPT slice. DragonFly, by default, creates a GPT slice for all of DragonFly and places a DragonFly disklabel inside it with all the standard DFly partitions, such that the disk names are roughly the same as they would be in a legacy system. Improved graphics support The i915 driver has been updated to match the version found with the Linux 4.6 kernel. Broadwell and Skylake processor users will see improvements. Other user-affecting changes Kernel is now built using -O2. VKernels now use COW, so multiple vkernels can share one disk image. powerd() is now sensitive to time and temperature changes. Non-boot-filesystem kernel modules can be loaded in rc.conf instead of loader.conf. *** #8005 poor performance of 1MB writes on certain RAID-Z configurations (https://github.com/openzfs/openzfs/pull/321) Matt Ahrens posts a new patch for OpenZFS Background: RAID-Z requires that space be allocated in multiples of P+1 sectors,because this is the minimum size block that can have the required amount of parity. Thus blocks on RAIDZ1 must be allocated in a multiple of 2 sectors; on RAIDZ2 multiple of 3; and on RAIDZ3 multiple of 4. A sector is a unit of 2^ashift bytes, typically 512B or 4KB. To satisfy this constraint, the allocation size is rounded up to the proper multiple, resulting in up to 3 "pad sectors" at the end of some blocks. The contents of these pad sectors are not used, so we do not need to read or write these sectors. However, some storage hardware performs much worse (around 1/2 as fast) on mostly-contiguous writes when there are small gaps of non-overwritten data between the writes. Therefore, ZFS creates "optional" zio's when writing RAID-Z blocks that include pad sectors. If writing a pad sector will fill the gap between two (required) writes, we will issue the optional zio, thus doubling performance. The gap-filling performance improvement was introduced in July 2009. Writing the optional zio is done by the io aggregation code in vdevqueue.c. The problem is that it is also subject to the limit on the size of aggregate writes, zfsvdevaggregationlimit, which is by default 128KB. For a given block, if the amount of data plus padding written to a leaf device exceeds zfsvdevaggregation_limit, the optional zio will not be written, resulting in a ~2x performance degradation. The solution is to aggregate optional zio's regardless of the aggregation size limit. As you can see from the graphs, this can make a large difference in performance. I encourage you to read the entire commit message, it is well written and very detailed. *** Can you spot the OpenSSL vulnerability (https://guidovranken.wordpress.com/2017/01/28/can-you-spot-the-vulnerability/) This code was introduced in OpenSSL 1.1.0d, which was released a couple of days ago. This is in the server SSL code, ssl/statem/statemsrvr.c, sslbytestocipherlist()), and can easily be reached remotely. Can you spot the vulnerability? So there is a loop, and within that loop we have an ‘if' statement, that tests a number of conditions. If any of those conditions fail, OPENSSLfree(raw) is called. But raw isn't the address that was allocated; raw is increment every loop. Hence, there is a remote invalid free vulnerability. But not quite. None of those checks in the ‘if' statement can actually fail; earlier on in the function, there is a check that verifies that the packet contains at least 1 byte, so PACKETget1 cannot fail. Furthermore, earlier in the function it is verified that the packet length is a multiple of 3, hence PACKETcopybytes and PACKET_forward cannot fail. So, does the code do what the original author thought, or expected it to do? But what about the next person that modifies that code, maybe changing or removing one of the earlier checks, allowing one of those if conditions to fail, and execute the bad code? Nonetheless OpenSSL has acknowledged that the OPENSSL_free line needs a rewrite: Pull Request #2312 (https://github.com/openssl/openssl/pull/2312) PS I'm not posting this to ridicule the OpenSSL project or their programming skills. I just like reading code and finding corner cases that impact security, which is an effort that ultimately works in everybody's best interest, and I like to share what I find. Programming is a very difficult enterprise and everybody makes mistakes. Thanks to Guido Vranken for the sharp eye and the blog post *** Research Debt (http://distill.pub/2017/research-debt/) I found this article interesting as it relates to not just research, but a lot of technical areas in general Achieving a research-level understanding of most topics is like climbing a mountain. Aspiring researchers must struggle to understand vast bodies of work that came before them, to learn techniques, and to gain intuition. Upon reaching the top, the new researcher begins doing novel work, throwing new stones onto the top of the mountain and making it a little taller for whoever comes next. People expect the climb to be hard. It reflects the tremendous progress and cumulative effort that's gone into the research. The climb is seen as an intellectual pilgrimage, the labor a rite of passage. But the climb could be massively easier. It's entirely possible to build paths and staircases into these mountains. The climb isn't something to be proud of. The climb isn't progress: the climb is a mountain of debt. Programmers talk about technical debt: there are ways to write software that are faster in the short run but problematic in the long run. Poor Exposition – Often, there is no good explanation of important ideas and one has to struggle to understand them. This problem is so pervasive that we take it for granted and don't appreciate how much better things could be. Undigested Ideas – Most ideas start off rough and hard to understand. They become radically easier as we polish them, developing the right analogies, language, and ways of thinking. Bad abstractions and notation – Abstractions and notation are the user interface of research, shaping how we think and communicate. Unfortunately, we often get stuck with the first formalisms to develop even when they're bad. For example, an object with extra electrons is negative, and pi is wrong Noise – Being a researcher is like standing in the middle of a construction site. Countless papers scream for your attention and there's no easy way to filter or summarize them. We think noise is the main way experts experience research debt. There's a tradeoff between the energy put into explaining an idea, and the energy needed to understand it. On one extreme, the explainer can painstakingly craft a beautiful explanation, leading their audience to understanding without even realizing it could have been difficult. On the other extreme, the explainer can do the absolute minimum and abandon their audience to struggle. This energy is called interpretive labor Research distillation is the opposite of research debt. It can be incredibly satisfying, combining deep scientific understanding, empathy, and design to do justice to our research and lay bare beautiful insights. Distillation is also hard. It's tempting to think of explaining an idea as just putting a layer of polish on it, but good explanations often involve transforming the idea. This kind of refinement of an idea can take just as much effort and deep understanding as the initial discovery. + The distillation can often times require an entirely different set of skills than the original creation of the idea. Almost all of the BSD projects have some great ideas or subsystems that just need distillation into easy to understand and use platforms or tools. Like the theoretician, the experimentalist or the research engineer, the research distiller is an integral role for a healthy research community. Right now, almost no one is filling it. Anyway, if that bit piqued your interest, go read the full article and the suggested further reading. *** News Roundup And then the murders began. (https://blather.michaelwlucas.com/archives/2902) A whole bunch of people have pointed me at articles like this one (http://thehookmag.com/2017/03/adding-murders-began-second-sentence-book-makes-instantly-better-125462/), which claim that you can improve almost any book by making the second sentence “And then the murders began.” It's entirely possible they're correct. But let's check, with a sampling of books. As different books come in different tenses and have different voices, I've made some minor changes. “Welcome to Cisco Routers for the Desperate! And then the murders begin.” — Cisco Routers for the Desperate, 2nd ed “Over the last ten years, OpenSSH has become the standard tool for remote management of Unix-like systems and many network devices. And then the murders began.” — SSH Mastery “The Z File System, or ZFS, is a complicated beast, but it is also the most powerful tool in a sysadmin's Batman-esque utility belt. And then the murders begin.” — FreeBSD Mastery: Advanced ZFS “Blood shall rain from the sky, and great shall be the lamentation of the Linux fans. And then, the murders will begin.” — Absolute FreeBSD, 3rd Ed Netdata now supports FreeBSD (https://github.com/firehol/netdata) netdata is a system for distributed real-time performance and health monitoring. It provides unparalleled insights, in real-time, of everything happening on the system it runs (including applications such as web and database servers), using modern interactive web dashboards. From the release notes: apps.plugin ported for FreeBSD Check out their demo sites (https://github.com/firehol/netdata/wiki) *** Distrowatch Weekly reviews RaspBSD (https://distrowatch.com/weekly.php?issue=20170220#raspbsd) RaspBSD is a FreeBSD-based project which strives to create a custom build of FreeBSD for single board and hobbyist computers. RaspBSD takes a recent snapshot of FreeBSD and adds on additional components, such as the LXDE desktop and a few graphical applications. The RaspBSD project currently has live images for Raspberry Pi devices, the Banana Pi, Pine64 and BeagleBone Black & Green computers. The default RaspBSD system is quite minimal, running a mere 16 processes when I was logged in. In the background the operating system runs cron, OpenSSH, syslog and the powerd power management service. Other than the user's shell and terminals, nothing else is running. This means RaspBSD uses little memory, requiring just 16MB of active memory and 31MB of wired or kernel memory. I made note of a few practical differences between running RaspBSD on the Pi verses my usual Raspbian operating system. One minor difference is RaspBSD turns off the Pi's external power light after booting. Raspbian leaves the light on. This means it looks like the Pi is off when it is running RaspBSD, but it also saves a little electricity. Conclusions: Apart from these little differences, running RaspBSD on the Pi was a very similar experience to running Raspbian and my time with the operating system was pleasantly trouble-free. Long-term, I think applying source updates to the base system might be tedious and SD disk operations were slow. However, the Pi usually is not utilized for its speed, but rather its low cost and low-energy usage. For people who are looking for a small home server or very minimal desktop box, RaspBSD running on the Pi should be suitable.

The AnandTech podcast is back once more, this time with Ian and Andrei recapping their time at Mobile World Congress 2015. We kick things off with a look at the flagship smartphones to come out of the show, Samsung's Galaxy S6 and HTC's One M9. We follow this up with a look at some of the photography-centric products to come out of the show, including the Lenovo Vibe Shot and Panasonic Lumix CM1. Of course no MWC would be complete without SoCs, and MWC has Qualcomm's Snapdragon 820, ARM's forthcoming Cortex-A72 CPU, and Intel's new Atom x3/x5/x7 brands. Then we switch gears to peripherals, including Qualcomm's new ultrasonic fingerprint scanning tech, Sandisk's hybrid eMMC tech, and modem tech from Broadcom and Altair. Finally we close things out with SteamVR and the first supporting headset, the HTC Vive.

So at DEF CON this year we’re doing exactly that, we’re hacking everything. We’ve taken all of our previous experience exploiting embedded devices and used it to bring you a presentation filled with more exploits than ever before™. This presentation will feature exploits for over 20 devices including but not limited to TVs, baby monitors, media streamers, network cameras, home automation devices, and VoIP gateways. Gain root on your devices, run unsigned kernels; it’s your hardware, it’s internet connected, and it’s horribly insecure. We will also be following last year’s tradition of handing out free hardware to assist the community in rooting their devices. This year we will have a select number of eMMC adapters for presentation attendees. Amir Etemadieh (@zenofex) is a Research Scientist on the R&D team at Accuvant LABS. Amir founded the GTVHacker group which has released public exploits for every device within the Google TV platform as well as multiple other non-Google TV devices including The Roku Media Player and The Google Chromecast. Prior to starting GTVHacker, Amir conducted independent research on a long list of consumer devices and is currently listed on multiple "Security Hall of Fame" pages for successfully completing bug bounties. CJ Heres (@cj_000) is an IT systems manager and security consultant who works with a simple philosophy: using a simple approach, one can solve most complex problems. CJ's recent work has been heavily focused on consumer electronics including Blu-Ray players, thermostats, Smart TVs, media streaming devices such as the Roku and Google TV, DVR's, and everything inbetween. CJ has previously spoken at DEF CON 20 and 21, as well as B-Sides Boston 2013. Mike Baker (@gtvhacker) (AKA [mbm]) is a firmware developer, better known as the Co-Founder behind OpenWrt. He hacks stuff. Hans Nielsen (@n0nst1ck) is a security wizard at Matasano Security. When he isn't busy protecting your in-house and external applications from evil, he enjoys writing software, hacking apart consumer electronics, designing prototype boards. Hans is a tinkerer at heart with an ability to quickly reverse and/or design hardware and software through whatever means necessary.
