This week's EYE ON NPI is another great step forward in Bluetooth Low Energy development, it's Nordic's new nRF54 series (https://www.digikey.com/en/product-highlight/n/nordic-semi/nrf54l15-multiprotocol-soc) and nRF54L15 Wireless SoC Development Kit (https://www.digikey.com/en/product-highlight/n/nordic-semi/nrf54l15-wireless-soc-development-kit). This is the heir-apparent to the popular nRF52840 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52840-CKAA-R/15929796) series chip which we know and love so much. The nRF54 series comes in L and H variants, for 'low' and 'high' power, but even the L series is a step up, with Cortex M33 running at 128MHz, and up to 1.5MB ReRAM (https://en.wikipedia.org/wiki/Resistive_random-access_memory) / 256KB SRAM. The H series is a whole new ball-game with dual M33 running at 320MHz, 2MB of ReRAM and 1MB of SRAM plus upgraded peripherals. Wow, the nRF series has come such a long way from the baby-steps of the SPI-peripheral nRF8001 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF8001-R2Q32-T/4626390) to the early ARM Cortex M0 plus BLE combo chip, the nRF51 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF51822-QFAB-R7/4626396). We still use that nRF51 in many of our Bluetooth LE boards like the Feather 32u4 and M0 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/2995/5823444), also as a SPI-peripheral-to-BLE converter. The next big upgrade was the nRF52832 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52832-QFAB-R/6051565) which bumped the processor from an M0 to an M4, but didn't do a huge bump to the Flash or SRAM compared the nRF51. The big leap after that was the nRF52840 which is still an amazing chip: USB peripheral means you can use this chip as the main processor, and it can do all your processing, user interface, sensor reading and wireless communication with only a few passives to support it. There was an nRF5340 released about two years ago (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF5340-CLAA-R/14323741) but much like Windows releases, we tend to skip every other chip. We happened to check digikey.com/new yesterday and saw the nRF54L (https://www.digikey.com/short/zf8pz0cr) series pop up, which is exciting as it was pre-announced about a year ago (https://www.youtube.com/watch?v=XG8bRNaNHrg) and is now shipping to customers! The nRF54L (https://www.digikey.com/short/zf8pz0cr) comes in three variants, which is not surprising because we've seen earlier chips come in 'lite' versions that cut pricing by having less flash or RAM. All variants have a 128MHz Cortex M33 with a RISC-V co-processor, and a BLE stack. One interesting thing we noted, is that instead of flash memory, which is big and expensive and hard to do with modern fab processes, the nRF54 uses ReRAM (https://en.wikipedia.org/wiki/Resistive_random-access_memory) which is non-volatile and uses memristor technology, which is pretty cool! The nRF54 series supports BLE 6, one new capability is channel sounding (https://en.wikipedia.org/wiki/Channel_sounding) which will improve the ability of phones to locate 'find my' tags that have become such a popular usage for the nRF chipset. Traditionally, the nRF52 chips in these tags use RSSI to measure approximate distance. There's been some improvements on the technology such as Angle-of-Attack that was introduced in BLE 5.1 (https://www.youtube.com/watch?v=EosGQtGioiY) but now with a broad-sprectrum burst it's looking like some of the lessons from UWB (https://blog.adafruit.com/2024/03/15/sera-nx040-ultra-wide-band-and-bluetooth-combo-module-eyeonnpi-digikey-digikey-lairdconnect-adafruit/) are being integrated to the BLE specification to improve item location. The nRF54L series is launching with the L15 variant (https://www.digikey.com/short/rd9fr19f), that's the one with the most memory, so it's a good start: once you have your design settled you can transition to the smallest chip you can get away with. They're coming into stock shortly so sign up at DigiKey to get notified when the package you're looking for arrives. While you wait, you can order up one of the nRF54L15-DK (https://www.digikey.com/short/qvhqv85q) dev kits, which are only $39 and in stock right now for immediate shipment. Order today and you'll get everything you need to start developing the nRF54 (https://www.nordicsemi.com/Products/Development-hardware/nRF54L15-DK) - a built in debugger, power management chip, broken out GPIO, user buttons and LEDs. While you wait for your dev kit to arrive, you can start thinking about the nRF54H series (https://www.nordicsemi.com/Products/nRF54H20) which is the high-end chip with dual M33 running at 320 MHz, 1 MB of SRAM, 2MB of ReRAM , high speed USB and I3C support (https://www.youtube.com/watch?v=hC4zkvdVag4)!

実施日時: 2024年11月3日　日曜礼拝　メッセンジャー: 吉田耕三牧師　聖書箇所: ローマ15章14～21節　長さ・サイズ: 28:37 (26.2MB)

1GB blocks are coming. Since November last year, 20 rollups have launched according to Celenium, the Celestia block explorer and those rollups have since published over 75GB of data. Following the Lemongrass upgrade, Celestia will aim to execute the roadmap across three different core tracks with the broader vision of enabling end-user verifiability to the fullest extent possible. 1. Abundant Blockspace: Targeting 1GB blocks to scale for a wide range of rollups. 2. Verifiable Blockspace: Ensures blockspace can be verified by any user, on any device. 3. Frictionless Blockspace: Reduces friction for rollup developers and users. Celestia being inherently modular means the chain isn't limited by execution layer overhead or state bloat. This flexibility allows for high-throughput apps, speeding up existing crypto applications and enabling new possibilities, like fully onchain apps. In today's special podcast, we're diving into Celestia's roadmap and what it means for the future of the modular ecosystem with Nick White. Nick, the COO of Celestia, walks us through the next phase of their roadmap. One of the most significant shifts is the move from 2MB to 1GB blocks, entering the "fiber-optic" era of DA, where abundant block space could transform onchain possibilities. ...However, do we really need all this blockspace? Where are the novel apps? Will Celestia transition to validity proof sampling? How will Celestia make it easy for anyone to run a light node? These questions and many more answered in today's pod as we break down the key takeaways from Nick's insights and what they mean for the modular ecosystem.

Episode 196   There's something we take for granted these days, something that wasn't even possible a short while ago. Let's go back to 2008, to the first iPhone, the 3G. What you could send & receive with one, if you could afford the data plan, was restricted to voice, text & small images. That's because at the time, the cellular networks could transmit at around a third of a Megabyte per second, which went up to 2Mb/second when 3G was fully available. Then LTE/4G started becoming available in North America, reaching 97 percent by 2013. With those data speeds, you could watch brief standard definition videos, and social networks like Instagram & Snapchat began letting you record and send short clips. By the late twenty teens, advanced 4G infrastructure was fast enough, from 12 to 80 MPS, for people to watch 4K videos on their devices, bringing platforms like TikTok along with it. Now with 5G out, lag-free high-def video is available almost everywhere. And if you are a marketer trying to reach consumers, it means that  video must be part of the mix.    There are still quirks to these platforms that we need to figure out. Some of their ad units include ecommerce options for selling products while the ad's in front of them. More broad that this, it's hard to know how these platforms will react to videos you post. They know so much about a user's privacy, it's raised issues of which country that data's shared with. Clearly, this calls for an expert's help.     Our guest graduated from San Francisco State University and FIDM with a business degree and started working in-house at consumer eCommerce brands, running their digital marketing programs. After helping brands in every category from skincare & cosmetics to Books to jewelry, she built her own agency team to do this, Pennock, which is named after the rural Minnesota town where her family are from.  Let's go to  Northern California where she lives with her husband Tyler and three kids, to talk to Nikki Lindgren.   Chapter Timestamps: 00:00:00 - Intro 00:03:12 - Welcome Nikki 00:09:05 - Video on platforms like TikTok 00:23:37 - PSA 00:24:26 - Reporting to stakeholders 00:29:59 - Ad campaign optimization 00:35:05 - Contacting Nikki   Links to all the people, products and concepts mentioned in show is available on the Funnel Reboot site's show page.

We're slowly but surely trying to de-SAMD51'ify our product line since that chip has a 2024 ETA. a bummer because we really loved that chip but it's probably a good time to transition since it can be a year until we get some and even then, the dates have been pushed multiple times. so, first up is the matrix portal m4 https://www.adafruit.com/product/4745 ! instead of a samd51 + esp32, we've got a version with ESP32-S3 WROOM which has 8MB of flash, and 2MB of PSRAM. the S3 has a nice peripheral that can be used to drive these matricies very fast, and the 2 MB of PSRAM will make this possible to drive lots of panels! we kept the same outline shape and functionality, including the built in accelerometer, which makes this LED sand demo a quick port.

Story 64 from 'A Lifetime Doing Nothing' by Ian McCrorie. When someone says hello to me in Korean, I invariably reply “kamsahamnida.” My response is immediate and trips naturally off my tongue. Unfortunately “kamsahamnida” does not mean “hello.” It means, “thank you.” But I don't care. To my ear, “kamsahamnida” sounds like a greeting. It sounds more like a... narrated by Ian McCrorie 2022 3 minutes 39 seconds Listen to Streaming Audio Your browser does not support the audio element.

Welcome to the Chicago Beer Pass: Your ticket to all the great beer events happening in and around Chicago.On this episode of Chicago Beer Pass, Brad Chmielewski and Nik White are doubling down with two different IPAs in December. Both of the IPAs the guys are drinking come from Penrose Brewing Company in Geneva. Brad got these cans a few months ago when he was out in the suburbs on his Oktoberfest crawl, so they have been hanging out in the fridge for a couple months. At a time of the year when stouts and big winter beers have taken over the shelves, it’s nice to have a great IPA.As the guys crush these cans, they talk about Nik’s trip to Bixi Beer in Logan Square. For years both Nik and Brad haven’t been the biggest fans of Bixi, but that may have changed. Not only was Nik’s recent trip there delicious, he also learned that Pipeworks will be taking over as guest brewer there. The idea that Pipeworks is taking over the space is very, very interesting. However, this news raises many questions about what that means for Bixi and Pipeworks going forward.Having issues listening to the audio? Try the MP3 (55.2MB) or subscribe to the podcast on iTunes!

Story 59 from 'A Lifetime Doing Nothing' by Ian McCrorie. I have spent most of my adult life avoiding gainful employment. I remember telling my guidance counselor at the age of fourteen that I wanted to be a shepherd. I pictured myself lazing under a giant oak, my trusty staff at my side, ready to rescue any wayward sheep. But shepherding was not on his list of future occupations, so he checked off actuary for me. For years I thought the two were synonymous. narrated by Ian McCrorie 2022 3 minutes 37 seconds Listen to Streaming Audio Your browser does not support the audio element.

Story 58 from 'A Lifetime Doing Nothing' by Ian McCrorie. I don't do fun. I shun hysteria. I never understood the causal relationship between indulging in a fun activity and happiness. Having the bejesus scared out of me on a roller-coaster is not, in and of itself (as we used to insert into arguments in Philosophy 101), fun. It is terrifying. The fun can only arise, if at all, when the ride is... narrated by Ian McCrorie 2022 3 minutes 36 seconds Listen to Streaming Audio Your browser does not support the audio element.

Story 47 from 'A Lifetime Doing Nothing' by Ian McCrorie. We used to drive to Toronto every Christmas vacation to spend the holidays with my grandmother.

In 2010 haalde Disney de eerder geflopte maar intussen tot cultstatus verheven film ‘TRON' uit 1982 van onder het stof met een reboot. Cultuurjournalist Ben Van Alboom was de geknipte man voor de organisatie van een Belgische avant première, mét after party. Op de gastenlijst: seksuoloog Wim Slabbinck. Retrospectief gesproken blijft ‘TRON' een mijlpaal, als een van de eerste films die zo intens gebruik maakte van digitale animatie, gemaakt op een computer met amper 2MB geheugen. We zagen een Jeff Bridges als posterboy. Maar ook een profetisch verhaal over privacy, data en open source-systemen, stelt Wim vast. Maar ook het ontwerp is bijna te vergelijken met de manuscripten van de monniken. En hij legt een link met het Covid Safe Ticket. Ben weet dan weer dat Tron vandaag een crypto-currency is. De vervolgfilm ‘TRON: Legacy' was een visueel snoepje, maar kon het het origineel overstijgen? Los van de fenomenale muziek van Daft Punk, natuurlijk. Het is het perfecte opstapje naar het tweede seizoen van de podcast die volgende week start met de eerste Pixar-film, de eerste langspeelfilm die integraal met de computer werd gemaakt. Die eerste uitzending kan je live bijwonen in Cinema Cartoon's in Antwerpen op zondag 24 april, gevolgd door een uitzonderlijke vertoning van Pixars laatste: ‘Turning Red'!

Today's episode with Barbara Arrowsmith-Young and Drew will open your mind to new possibilities in how you can change your brain. Barbara is an innovator and author in the field of neuroeducation. Used worldwide, her work utilizing the principles of neuroplasticity to enhance cognitive functioning was begun in 1978. Barbara's vision is to put the brain into the education equation. She is passionate about enhancing “the learner's ability to engage with what is out there in the external world.” In order to support herself in bringing this gift she'd created into the world, Barbara came to the Hoffman Process in 1996. In other words, she had a vision but needed to clear the negative behaviors, moods, and ways of thinking standing in her way. As a result, Barbara has made and continues to make her vision a reality. Looking forward, she sees promise in her work to help addicts rewire their brains, as well as helping those with the cognitive impact of long-haul Covid. Through fierce dedication, Barbara has transformed the considerable challenges she was born with into the gift she now shares with the world. She says she won't ever retire; that she'll continue to work in this area until she is “no longer here.“ More About Barbara and her work: As the Director of the Arrowsmith Program, others have recognized Barbara's work as one of the first examples of the practical application of neuroplasticity to address learning difficulties. Barbara continues to engage in research to understand how we can drive neuroplastic change in the brain to benefit learners worldwide. Born with severe learning disabilities, Barbara received the diagnosis of having a mental block in grade one. Another way of saying this in today's world would be multiple learning disabilities. Barbara read and wrote everything backward. In addition, processing concepts in language was difficult for her, she continuously got lost, and was physically uncoordinated. Through heroic effort, Barbara eventually learned to read and write from left to right and mask a number of the symptoms of her learning disabilities. Relying on her formidable memory and iron will, she made her way to graduate school. There she chanced upon research that inspired her to invent cognitive exercises to “fix” her own brain. Barbara's book, The Woman Who Changed Her Brain, interweaves her personal tale with riveting case histories from her more than thirty years of working with both children and adults.

La naissance d'une mère peut parfois se faire dans la douleur. Mais quand est-il de la naissance d'un père ? Les jeunes pères peuvent aussi subir des chute d'hormone à la naissance de leur bébé. Certains sont aussi sensible à un déclanchement d'un mal-être plus ancien. Autant de raison qui peuvent déclencher une dépression post partum chez les papas.Dans cet épisode, Antoine vous raconte son histoire, sa dépression post partum. Quels en sont les causes, comment elle s'est installée, comment elle se manifestait ? Et on revient évidemment sur la nécessité de sortir de l'isolement, de parler, de se faire accompagner.

Chez un fœtus la trachée et l'œsophage ne forment qu'un au début de sa vie et se divise aux alentours de la 4e semaine de grossesse. Mais dans certains cas cette division peut mal se passer et il en résulte alors une atrésie de l'œsophage.C'est une malformation congénitale peu connue dont la petite Jeanne souffre. Qui dit peu connu dit forcément sensibilisation des médecins, des familles et du milieu éducatif. Et c'est aussi le but de cet épisode. Car le combat de ces guerriers extraordinaires n'est pas si simple et il peut parfois être rempli de complications. Solène revient sur la première année de sa fille Jeanne qui fut vraiment une terrible expérience. Mais malgré tout, elle en parle avec beaucoup de sagesse et de courage. Alors comment on vit ces premiers instants de mères tout en ayant son bébé maintenu en vie par de multiples sondes ? Comment arrive - t-on à rester fort pour vivre le quotidien malgré tout ? Comment on fait pour avancer et avoir confiance quand l'équipe médicale n'est, elle-même, pas sûre de ses diagnostics ?Voici l'histoire émouvante de Solène et sa fille Jeanne.-----------------------------------------------Liens utiles :AFAO - Association Française de l'Atrésie de l'Œsophage-----------------------------------------------Si vous aimez ce podcast et que vous voulez m'aider à le faire grandir, prenez le temps de mettre 5 étoiles sur Apple podcast et un commentaire.Retrouvez moi surInstagram @gdtp.podcast / https://www.instagram.com/gdtp.podcast/Facebook https://www.facebook.com/gdtp.podcast Pour ne manquer aucun épisodes et découvrir les coulisses : http://eepurl.com/hp_6nb Pour témoigner de votre histoire : grandsdefistoutpetits@gmail.com Bonne écoute !------------------------------------------------Création originale : Nadia DavoulouryProduction, enregistrement, montage : Nadia DavoulouryDesign by @estellesableMusique originale by @diyopmusique (https://www.facebook.com/diyopmusique)Titre: Intro To WoumAuteur: CloudKickerSource: https://cloudkicker.bandcamp.comLicence: https://creativecommons.org/licenses/by/3.0/deed.frTéléchargement (2MB): https://auboutdufil.com/?id=474 Voir Acast.com/privacy pour les informations sur la vie privée et l'opt-out.

Allan reports on his trip to BSD Taiwan, new versions of Lumina and GhostBSD are here, a bunch of OpenBSD p2k17 hackathon reports. This episode was brought to you by Headlines Allan's Trip Report from BSD Taiwan (https://bsdtw.org/) BSD TW and Taiwan in general was a fun and interesting experience I arrived Thursday night and took the high speed train to Taipei main station, and then got on the Red line subway to the venue. The dorm rooms were on par with BSDCan, except the mattress was better. I spent Friday with a number of other FreeBSD developers doing touristy things. We went to Taipei 101, the world's tallest building from 2004 - 2010. It also features the world's fastest elevator (2004 - 2016), traveling at 60.6 km/h and transporting passengers from the 5th to 89th floor in 37 seconds. We also got to see the “tuned mass damper”, a 660 tonne steel pendulum suspended between the 92nd and 87th floors. This device resists the swaying of the building caused by high winds. There are interesting videos on display beside the damper, of its reaction during recent typhoons and earthquakes. The Taipei 101 building sits just 200 meters from a major fault line. Then we had excellent dumplings for lunch After walking around the city for a few more hours, we retired to a pub to escape the heat of the sunny Friday afternoon. Then came the best part of each day in Taipei, dinner! We continued our efforts to cause a nation wide shortage of dumplings Special thanks to Scott Tsai (https://twitter.com/scottttw) who took detailed notes for each of the presentations Saturday marked the start of the conference: Arun Thomas provided background and then a rundown of what is happening with the RISC-V architecture. Notes (https://docs.google.com/document/d/1yrnhNTHaMDr4DG-iviXN0O9NES9Lmlc7sWVQhnios6g/edit#heading=h.kcm1n3yzl35q) George Neville-Neil talked about using DTrace in distributed systems as an in-depth auditing system (who did what to whom and when). Notes (https://docs.google.com/document/d/1qut6tMVF8NesrGHd6bydLDN-aKBdXMgHx8Vp3_iGKjQ/edit#heading=h.qdghsgk1bgtl) Baptiste Daroussin presented Poudrière image, an extension of everyone's favourite package building system, to build custom images of FreeBSD. There was discussion of making this generate ZFS based images as well, making it mesh very well with my talk the next day. Notes (https://docs.google.com/document/d/1LceXj8IWJeTRHp9KzOYy8tpM00Fzt7fSN0Gw83B9COE/edit#heading=h.incfzi6bnzxr) Brooks Davis presented his work on an API design for a replacement for mmap. It started with a history of address space management in the BSD family of operating systems going all the way back to the beginning. This overview of the feature and how it evolved filled in many gaps for me, and showed why the newer work would be beneficial. The motivation for the work includes further extensions to support the CHERI hardware platform. Notes (https://docs.google.com/document/d/1LceXj8IWJeTRHp9KzOYy8tpM00Fzt7fSN0Gw83B9COE/edit#heading=h.incfzi6bnzxr) Johannes M Dieterich gave an interesting presentation about using FreeBSD and GPU acceleration for high performance computing. One of the slides showed that amd64 has taken almost the entire market for the top 500 super computers, and that linux dominates the list, with only a few remaining non-linux systems. Sadly, at the supercomputing conference the next week, it was announced that linux has achieved 100% saturation of the top 500 super computers list. Johannes detailed the available tools, what ports are missing, what changes should be made to the base system (mostly OpenMP), and generally what FreeBSD needs to do to become a player in the supercomputer OS market. Johannes' perspective is interesting, as he is a computational chemist, not a computer scientist. Those interested in improving the numerical libraries and GPU acceleration frameworks on FreeBSD should join the ports team. Notes (https://docs.google.com/document/d/1uaJiqtPk8WetST6_GnQwIV49bj790qx7ToY2BHC9zO4/edit#heading=h.nvsz1n6w3gyq) The final talk of the day was Peter Grehan, who spoke about how graphics support in bhyve came to be. He provided a history of how the feature evolved, and where it stands today. Notes (https://docs.google.com/document/d/1LqJQJUwdUwWZ0n5KwCH1vNI8jiWGJlI1j0It3mERN80/edit#heading=h.sgeixwgz7bjs) Afterwards, we traveled as a group to a large restaurant for dinner. There was even Mongolian Vodka, provided by Ganbold Tsagaankhuu of the FreeBSD project. Sunday: The first talk of the day Sunday was mine. I presented “ZFS: Advanced Integration”, mostly talking about how boot environments work, and the new libbe and be(1) tools that my GSoC student Kyle Kneitinger created to manage them. I talked about how they can be used for laptop and developer systems, but also how boot environments can be used to replace nanobsd for appliances (as already done in FreeNAS and pfSense). I also presented about zfsbootcfg (zfs nextboot), and some future extensions to it to make it even more useful in appliance type workloads. I also provided a rundown of new developments out of the ZFS developer summit, two weeks previous. Notes (https://docs.google.com/document/d/1Blh3Dulf0O91A0mwv34UnIgxRZaS_0FU2lZ41KRQoOU/edit#heading=h.gypim387e8hy) Theo de Raadt presented “Mitigations and other real Security Features”, and made his case for changing to a ‘fail closed' mode of interoperability. Computer's cannot actually self heal, so lets stop pretending that they can. Notes (https://docs.google.com/document/d/1fFHzlxJjbHPsV9t_Uh3PXZnXmkapAK5RkJsfaHki7kc/edit#heading=h.192e4lmbl70c) Ruslan Bukin talked about doing the port of FreeBSD for RISC-V and writing the Device Drivers. Ruslan walked through the process step by step, leading members of the audience to suggest he turn it into a developer's handbook article, explaining how to do the initial bringup on new hardware. Ruslan also showed off a FreeBSD/MIPS board he designed himself and had manufactured in China. Notes (https://docs.google.com/document/d/1kRhRr3O3lQ-0dS0kYF0oh_S0_zFufEwrdFjG1QLyk8Y/edit#heading=h.293mameym7w1) Mariusz Zaborski presented Case studies on sandboxing the base system with Capsicum. He discussed the challenges encountered as existing programs are modified to sandbox them, and recent advancements in the debugging tools available during that process. Mariusz also discussed the Casper service at length, including the features that are planned for 2018 and onwards. Notes (https://docs.google.com/document/d/1_0BpAE1jGr94taUlgLfSWlJOYU5II9o7Y3ol0ym1eZQ/edit#heading=h.xm9mh7dh6bay) The final presentation of the day was Mark Johnston on Memory Management Improvements in FreeBSD 12.0. This talk provided a very nice overview of the memory management system in FreeBSD, and then detailed some of the recent improvements. Notes (https://docs.google.com/document/d/1gFQXxsHM66GQGMO4-yoeFRTcmOP4NK_ujVFHIQJi82U/edit#heading=h.uirc9jyyti7w) The conference wrapped up with the Work-in-Progress session, including updates on: multi-device-at-once GELI attach, MP-safe networking on NetBSD, pkgsrc, NetBSD in general, BSD on Microsoft Azure, Mothra (send-pr for bugzilla), BSDMizer a machine learning compiler optimizer, Hyperledger Sawtooth (blockchain), and finally VIMAGE and pf testing on FreeBSD. Notes (https://docs.google.com/document/d/1miHZEPrqrpCTh8JONmUKWDPYUmTuG2lbsVrWDtekvLc/edit#heading=h.orhedpjis5po) Group Photo (https://pbs.twimg.com/media/DOh1txnVoAAFKAa.jpg:large) BSDTW was a great conference. They are still considering if it should be an annual thing, trade off every 2nd year with AsiaBSDCon, or something else. In order to continue, BSD Taiwan requires more organizers and volunteers. They have regular meetups in Taipei if you are interested in getting involved. *** Lumina 1.4.0 released (https://lumina-desktop.org/version-1-4-0-released/) The Lumina Theme Engine (and associated configuration utility) The Lumina theme engine is a new component of the “core” desktop, and provides enhanced theming capabilities for the desktop as well as all Qt5 applications. While it started out life as a fork of the “qt5ct” utility, it quickly grew all sorts of new features and functionality such as system-defined color profiles, modular theme components, and built-in editors/creators for all components. The backend of this engine is a standardized theme plugin for the Qt5 toolkit, so that all Qt5 applications will now present a unified appearance (if the application does not enforce a specific appearance/theme of it's own). Users of the Lumina desktop will automatically have this plugin enabled: no special action is required. Please note that the older desktop theme system for Lumina has been rendered obsolete by the new engine, but a settings-conversion path has already been implemented which should transition your current settings to the new engine the first time you login to Lumina 1.4.0. Custom themes for the older system may not be converted though, but it is trivial to copy/paste any custom stylesheets from the old system into the editor for the new theme engine to register/re-apply them as desired. Lumina-Themes Repository I also want to give a shout-out to the trueos/lumina-themes github repository contributors. All of the wallpapers in the 1.4.0 screenshots I posted come from that package, and they are working on making more wallpapers, color palettes, and desktop styles for use with the Lumina Theme Engine. If your operating system does not currently provide a package for lumina-themes, I highly recommend that you make one as soon as possible! The Lumina PDF Viewer (lumina-pdf) This is a new, stand-alone desktop utility for viewing/printing/presenting PDF documents. It uses the poppler-qt5 library in the backend for rendering the document, but uses multi-threading in many ways (such as to speed up the loading of pages) to give the user a nice, streamlined utility for viewing PDF documents. There is also built-in presentation functionality which allows users to easily cast the document to a separate screen without mucking about in system menus or configuration utilities. Lumina PDF Viewer (1.4.0) Important Packaging Changes One significant change of note for people who are packaging Lumina for their particular operating system is that the minimum supported versions of Qt for Lumina have been changed with this release: lumina-core: Qt 5.4+ lumina-mediaplayer: Qt 5.7+ Everything else: Qt 5.2+ Of course, using the latest version of the Qt5 libraries is always recommended. When packaging for Linux distributions, the theme engine also requires the availability of some of the “-dev” packages for Qt itself when compiling the theme plugin. For additional information (specifically regarding Ubuntu builds), please take a look at a recent ticket on the Lumina repository. + The new lumina-pdf utility requires the availability of the “poppler-qt5” library. The includes for this library on Ubuntu 17.10 were found to be installed outside of the normal include directories, so a special rule for it was added to our OS-Detect file in the Lumina source tree. If your particular operating system also places the the poppler include files in a non-standard place, please patch that file or send us the information and we can add more special rules for your particular OS. Other Changes of Note (in no particular order) lumina-config: Add a new page for changing audio theme (login, logout, low battery) Add option to replace fluxbox with some other WM (with appropriate warnings) Have the “themes” page redirect to launching the Lumina theme engine configuration utility. start-lumina-desktop: Auto-detect the active X11 displays and create a new display for the Lumina session (prevent conflict with prior graphical sessions). Add a process-failure counter & restart mechanism. This is particularly useful for restarting Fluxbox from time to time (such as after any monitor addition/removal) lumina-xconfig: Restart fluxbox after making any monitor changes with xrandr. This ensures a more reliable session. Implement a new 2D monitor layout mechanism. This allows for the placement of monitors anywhere in the X/Y plane, with simplification buttons for auto-tiling the monitors in each dimension based on their current location. Add the ability to save/load monitor profiles. Distinguish between the “default” monitor arrangement and the “current” monitor arrangement. Allow the user to set the current arrangement as the new default. lumina-desktop: Completely revamp the icon loading mechanisms so it should auto-update when the theme changes. Speed up the initialization of the desktop quite a bit. Prevent loading/probing files in the “/net/” path for existence (assume they exist in the interest of providing shortcuts). On FreeBSD, these are special paths that actually pause the calling process in order to mount/load a network share before resuming the process, and can cause significant “hangs” in the desktop process. Add the ability to take a directory as a target for the wallpaper. This will open/probe the directory for any existing image files that it can use as a wallpaper and randomly select one. Remove the popup dialog prompting about system updates, and replace it with new “Restart (with updates)” buttons on the appropriate menus/windows instead. If no wallpapers selection is provided, try to use the “lumina-nature” wallpaper directory as the default, otherwise fall back on the original default wallpaper if the “lumina-themes” package is not installed. lumina-open: Make the *.desktop parsing a bit more flexible regarding quoted strings where there should not be any. If selecting which application to use, only overwrite the user-default app if the option is explicitly selected. lumina-fileinfo: Significant cleanup of this utility. Now it can be reliably used for creating/registering XDG application shortcuts. Add a whole host of new ZFS integrations: If a ZFS dataset is being examined, show all the ZFS properties for that dataset. If the file being examined exists within ZFS snapshots, show all the snapshots of the file lumina-fm: Significant use of additional multi-threading. Makes the loading of directories much faster (particularly ones with image files which need thumbnails) Add detection/warning when running as root user. Also add an option to launch a new instance of lumina-fm as the root user. [FreeBSD/TrueOS] Fix up the detection of the “External Devices” list to also list available devices for the autofs system. Fix up some drag and drop functionality. Expose the creation, extraction, and insertion of files into archives (requires lumina-archiver at runtime) Expand the “Open With” option into a menu of application suggestions in addition to the “Other” option which runs “lumina-open” to find an application. Provide an option to set the desktop wallpaper to the selected image file(s). (If the running desktop session is Lumina). lumina-mediaplayer: Enable the ability to playback local video files. (NOTE: If Qt5 is set to use the gstreamer multimedia backend, make sure you have the “GL” plugin installed for smooth video playback). lumina-archiver: Add CLI flags for auto-archive and auto-extract. This allows for programmatic/scriptable interactions with archives. That is not mentioning all of the little bugfixes, performance tweaks, and more that are also included in this release. *** The strongest KASLR, ever? (https://blog.netbsd.org/tnf/entry/the_strongest_kaslr_ever) Re: amd64: kernel aslr support (https://mail-index.netbsd.org/tech-kern/2017/11/14/msg022594.html) So, I did it. Now the kernel sections are split in sub-blocks, and are all randomized independently. See my drawing [1]. What it means in practice, is that Kernel ASLR is much more difficult to defeat: a cache attack will at most allow you to know that a given range is mapped as executable for example, but you don't know which sub-block of .text it is; a kernel pointer leak will at most allow you to reconstruct the layout of one sub-block, but you don't know the layout and address of the remaining blocks, and there can be many. The size and number of these blocks is controlled by the split-by-file parameter in Makefile.amd64. Right now it is set to 2MB, which produces a kernel with ~23 allocatable (ie useful at runtime) sections, which is a third of the total number supported (BTSPACENSEGS = 64). I will probably reduce this parameter a bit in the future, to 1.5MB, or even 1MB. All of that leaves us with about the most advanced KASLR implementation available out there. There are ways to improve it even more, but you'll have to wait a few weeks for that. If you want to try it out you need to make sure you have the latest versions of GENERICKASLR / prekern / bootloader. The instructions are still here, and haven't changed. Initial design As I said in the previous episode, I added in October a Kernel ASLR implementation in NetBSD for 64bit x86 CPUs. This implementation would randomize the location of the kernel in virtual memory as one block: a random VA would be chosen, and the kernel ELF sections would be mapped contiguously starting from there. This design had several drawbacks: one leak, or one successful cache attack, could be enough to reconstruct the layout of the entire kernel and defeat KASLR. NetBSD's new KASLR design significantly improves this situation. New design In the new design, each kernel ELF section is randomized independently. That is to say, the base addresses of .text, .rodata, .data and .bss are not correlated. KASLR is already at this stage more difficult to defeat, since you would need a leak or cache attack on each of the kernel sections in order to reconstruct the in-memory kernel layout. Then, starting from there, several techniques are used to strengthen the implementation even more. Sub-blocks The kernel ELF sections are themselves split in sub-blocks of approximately 1MB. The kernel therefore goes from having: { .text .rodata .data .bss } to having { .text .text.0 .text.1 ... .text.i .rodata .rodata.0 ... .rodata.j ... .data ...etc } As of today, this produces a kernel with ~33 sections, each of which is mapped at a random address and in a random order. This implies that there can be dozens of .text segments. Therefore, even if you are able to conduct a cache attack and determine that a given range of memory is mapped as executable, you don't know which sub-block of .text it is. If you manage to obtain a kernel pointer via a leak, you can at most guess the address of the section it finds itself in, but you don't know the layout of the remaining 32 sections. In other words, defeating this KASLR implementation is much more complicated than in the initial design. Higher entropy Each section is put in a 2MB-sized physical memory chunk. Given that the sections are 1MB in size, this leaves half of the 2MB chunk unused. Once in control, the prekern shifts the section within the chunk using a random offset, aligned to the ELF alignment constraint. This offset has a maximum value of 1MB, so that once shifted the section still resides in its initial 2MB chunk: The prekern then maps these 2MB physical chunks at random virtual addresses; but addresses aligned to 2MB. For example, the two sections in Fig. A will be mapped at two distinct VAs: There is a reason the sections are shifted in memory: it offers higher entropy. If we consider a .text.i section with a 64byte ELF alignment constraint, and give a look at the number of possibilities for the location of the section in memory: The prekern shifts the 1MB section in its 2MB chunk, with an offset aligned to 64 bytes. So there are (2MB-1MB)/(64B)=214 possibilities for the offset. Then, the prekern uses a 2MB-sized 2MB-aligned range of VA, chosen in a 2GB window. So there are (2GB-2MB)/(2MB)=210-1 possibilities for the VA. Therefore, there are 214x(210-1)˜224 possible locations for the section. As a comparison with other systems: OS # of possibilities Linux 2^6 MacOS 2^8 Windows 2^13 NetBSD 2^24 Of course, we are talking about one .text.i section here; the sections that will be mapped afterwards will have fewer location possibilities because some slots will be already occupied. However, this does not alter the fact that the resulting entropy is still higher than that of the other implementations. Note also that several sections have an alignment constraint smaller than 64 bytes, and that in such cases the entropy is even higher. Large pages There is also a reason we chose to use 2MB-aligned 2MB-sized ranges of VAs: when the kernel is in control and initializes itself, it can now use large pages to map the physical 2MB chunks. This greatly improves memory access performance at the CPU level. Countermeasures against TLB cache attacks With the memory shift explained above, randomness is therefore enforced at both the physical and virtual levels: the address of the first page of a section does not equal the address of the section itself anymore. It has, as a side effect, an interesting property: it can mostly mitigate TLB cache attacks. Such attacks operate at the virtual-page level; they will allow you to know that a given large page is mapped as executable, but you don't know where exactly within that page the section actually begins. Strong? This KASLR implementation, which splits the kernel in dozens of sub-blocks, randomizes them independently, while at the same time allowing for higher entropy in a way that offers large page support and some countermeasures against TLB cache attacks, appears to be the most advanced KASLR implementation available publicly as of today. Feel free to prove me wrong, I would be happy to know! WIP Even if it is in a functional state, this implementation is still a work in progress, and some of the issues mentioned in the previous blog post haven't been addressed yet. But feel free to test it and report any issue you encounter. Instructions on how to use this implementation can still be found in the previous blog post, and haven't changed since.

We explore whether a BSD can replicate Cisco router performance; RETGUARD, OpenBSDs new exploit mitigation technology, Dragonfly's HAMMER2 filesystem implementation & more! This episode was brought to you by Headlines Can a BSD system replicate the performance of a Cisco router? (https://www.reddit.com/r/networking/comments/6upchy/can_a_bsd_system_replicate_the_performance_of/) Short Answer: No, but it might be good enough for what you need Traditionally routers were built with a tightly coupled data plane and control plane. Back in the 80s and 90s the data plane was running in software on commodity CPUs with proprietary software. As the needs and desires for more speeds and feeds grew, the data plane had to be implemented in ASICs and FPGAs with custom memories and TCAMs. While these were still programmable in a sense, they certainly weren't programmable by anyone but a small handful of people who developed the hardware platform. The data plane was often layered, where features not handled by the hardware data plane were punted to a software only data path running on a more general CPU. The performance difference between the two were typically an order or two of magnitude. source (https://fd.io/wp-content/uploads/sites/34/2017/07/FDioVPPwhitepaperJuly2017.pdf) Except for encryption (e.g. IPsec) or IDS/IPS, the true measure of router performance is packets forwarded per unit time. This is normally expressed as Packets-per-second, or PPS. To 'line-rate' forward on a 1gbps interface, you must be able to forward packets at 1.488 million pps (Mpps). To forward at "line-rate" between 10Gbps interfaces, you must be able to forward at 14.88Mpps. Even on large hardware, kernel-forwarding is limited to speeds that top out below 2Mpps. George Neville-Neil and I did a couple papers on this back in 2014/2015. You can read the papers (https://github.com/freebsd-net/netperf/blob/master/Documentation/Papers/ABSDCon2015Paper.pdf) for the results. However, once you export the code from the kernel, things start to improve. There are a few open source code bases that show the potential of kernel-bypass networking for building a software-based router. The first of these is netmap-fwd which is the FreeBSD ip_forward() code hosted on top of netmap, a kernel-bypass technology present in FreeBSD (and available for linux). Full-disclosure, netmap-fwd was done at my company, Netgate. netmap-fwd will l3 forward around 5 Mpps per core. slides (https://github.com/Netgate/netmap-fwd/blob/master/netmap-fwd.pdf) The first of these is netmap-fwd (https://github.com/Netgate/netmap-fwd) which is the FreeBSD ip_forward() code hosted on top of netmap (https://github.com/luigirizzo/netmap), a kernel-bypass technology present in FreeBSD (and available for linux). Full-disclosure, netmap-fwd was done at my company, Netgate. (And by "my company" I mean that I co-own it with my spouse.). netmap-fwd will l3 forward around 5 Mpps per core. slides (https://github.com/Netgate/netmap-fwd/blob/master/netmap-fwd.pdf) Nanako Momiyama of the Keio Univ Tokuda Lab presented on IP Forwarding Fastpath (https://www.bsdcan.org/2017/schedule/events/823.en.html) at BSDCan this past May. She got about 5.6Mpps (roughly 10% faster than netmap-fwd) using a similar approach where the ip_foward() function was rewritten as a module for VALE (the netmap-based in-kernel switch). Slides (https://2016.eurobsdcon.org/PresentationSlides/NanakoMomiyama_TowardsFastIPForwarding.pdf) from her previous talk at EuroBSDCon 2016 are available. (Speed at the time was 2.8Mpps.). Also a paper (https://www.ht.sfc.keio.ac.jp/~nanako/conext17-sw.pdf) from that effort, if you want to read it. Of note: They were showing around 1.6Mpps even after replacing the in-kernel routing lookup algorithm with DXR. (DXR was written by Luigi Rizzo, who is also the primary author of netmap.) Not too long after netmap-fwd was open sourced, Ghandi announced packet-journey, an application based on drivers and libraries and from DPDK. Packet-journey is also an L3 router. The GitHub page for packet-journey lists performance as 21,773.47 mbps (so 21.77Gbps) for 64-byte UDP frames with 50 ACLs and 500,000 routes. Since they're using 64-byte frames, this translates to roughly 32.4Mpps. Finally, there is recent work in FreeBSD (which is part of 11.1-RELEASE) that gets performance up to 2x the level of netmap-fwd or the work by Nanako Momiyama. 10 million PPS: Here (http://blog.cochard.me/2015/09/receipt-for-building-10mpps-freebsd.html) is a decent introduction. But of course, even as FreeBSD gets up to being able to do 10gbps at line-rate, 40 and 100 gigabits are not uncommon now Even with the fastest modern CPUs, this is very little time to do any kind of meaningful packet processing. At 10Gbps, your total budget per packet, to receive (Rx) the packet, process the packet, and transmit (Tx) the packet is 67.2 ns. Complicating the task is the simple fact that main memory (RAM) is 70 ns away. The simple conclusion here is that, even at 10Gbps, if you have to hit RAM, you can't generate the PPS required for line-rate forwarding. There is some detail about design tradeoffs in the Ryzen architecture and how that might impact using those machines as routers Anyway... those are all interesting, but the natural winner here is FD.io's Vector Packet Processing (VPP). Read this (http://blogs.cisco.com/sp/a-bigger-helping-of-internet-please) VPP is an efficient, flexible open source data plane. It consists of a set of forwarding nodes arranged in a directed graph and a supporting framework. The framework has all the basic data structures, timers, drivers (and interfaces to both DPDK and netmap), a scheduler which allocates the CPU time between the graph nodes, performance and debugging tools, like counters and built-in packet trace. The latter allows you to capture the paths taken by the packets within the graph with high timestamp granularity, giving full insight into the processing on a per-packet level. The net result here is that Cisco (again, Cisco) has shown the ability to route packets at 1 Tb/s using VPP on a four socket Purley system There is also much discussion of the future of pfSense, as they transition to using VPP This is a very lengthy write up which deserves a full read, plus there are some comments from other people *** RETGUARD, the OpenBSD next level in exploit mitigation, is about to debut (https://marc.info/?l=openbsd-tech&m=150317547021396&w=2) This year I went to BSDCAN in Ottawa. I spent much of it in the 'hallway track', and had an extended conversation with various people regarding our existing security mitigations and hopes for new ones in the future. I spoke a lot with Todd Mortimer. Apparently I told him that I felt return-address protection was impossible, so a few weeks later he sent a clang diff to address that issue... The first diff is for amd64 and i386 only -- in theory RISC architectures can follow this approach soon. The mechanism is like a userland 'stackghost' in the function prologue and epilogue. The preamble XOR's the return address at top of stack with the stack pointer value itself. This perturbs by introducing bits from ASLR. The function epilogue undoes the transform immediately before the RET instruction. ROP attack methods are impacted because existing gadgets are transformed to consist of " RET". That pivots the return sequence off the ROP chain in a highly unpredictable and inconvenient fashion. The compiler diff handles this for all the C code, but the assembly functions have to be done by hand. I did this work first for amd64, and more recently for i386. I've fixed most of the functions and only a handful of complex ones remain. For those who know about polymorphism and pop/jmp or JOP, we believe once standard-RET is solved those concerns become easier to address seperately in the future. In any case a substantial reduction of gadgets is powerful. For those worried about introducing worse polymorphism with these "xor; ret" epilogues themselves, the nested gadgets for 64bit and 32bit variations are +1 "xor %esp,(%rsp); ret", +2 "and $0x24,%al; ret" and +3 "and $0xc3,%al; int3". Not bad. Over the last two weeks, we have received help and advice to ensure debuggers (gdb, egdb, ddb, lldb) can still handle these transformed callframes. Also in the kernel, we discovered we must use a smaller XOR, because otherwise userland addresses are generated, and cannot rely on SMEP as it is really new feature of the architecture. There were also issues with pthreads and dlsym, which leads to a series of uplifts around _builtinreturn_address and DWARF CFI. Application of this diff doesn't require anything special, a system can simply be built twice. Or shortcut by building & installing gnu/usr.bin/clang first, then a full build. We are at the point where userland and base are fully working without regressions, and the remaining impacts are in a few larger ports which directly access the return address (for a variety of reasons). So work needs to continue with handling the RET-addr swizzle in those ports, and then we can move forward.

It WILL be considered experimental and won't be an installer option yet. This initial release will only have single-image support operational plus basic features. It will have live dedup (for cp's), compression, fast recovery, snapshot, and boot support out of the gate. This first H2 release will not have clustering or multi-volume support, so don't expect those features to work. I may be able to get bulk dedup and basic mirroring operational by release time, but it won't be very efficient. Also, right now, sync operations are fairly expensive and will stall modifying operations to some degree during the flush, and there is no reblocking (yet). The allocator has a 16KB granularity (on HAMMER1 it was 2MB), so for testing purposes it will still work fairly well even without reblocking. The design is in a good place. I'm quite happy with how the physical layout turned out. Allocations down to 1KB are supported. The freemap has a 16KB granularity with a linear counter (one counter per 512KB) for packing smaller allocations. INodes are 1KB and can directly embed 512 bytes of file data for files 512 bytes. The freemap is also zoned by type for I/O locality. The blockrefs are 'fat' at 128 bytes but enormously powerful. That will allow us to ultimately support up to a 512-bit crypto hash and blind dedup using said hash. Not on release, but that's the plan. I came up with an excellent solution for directory entries. The 1KB allocation granularity was a bit high but I didn't want to reduce it. However, because blockrefs are now 128 byte entities, and directory entries are hashed just like in H1, I was able to code them such that a directory entry is embedded in the blockref itself and does not require a separate data reference or allocation beyond that. Filenames up to 64 bytes long can be accomodated in the blockref using the check-code area of the blockref. Longer filenames will use an additional data reference hanging off the blockref to accomodate up to 255 char filenames. Of course, a minimum of 1KB will have to be allocated in that case, but filenames are
