This week Jonathan and Rob chat with Tom Herbert about XDP2! It’s the brand new framework for making networking really fast, making parsers really simple, and making hardware network acceleration actually useful with Linux. https://medium.com/@tom_84912/xdp2-this-changes-everything-at-least-for-ai-ml-infrastructure-850c1ba82771 https://medium.com/@tom_84912/programming-a-parser-in-xdp2-is-as-easy-as-pie-8f26c8b3e704 Did you know you can watch the live recording of the show right on our YouTube Channel? Have someone […]
There was a recent recall of so-called ‘radioactive shrimp’ that were potentially contaminated with cesium-137 (Cs-137). But contamination isn’t an all-or-nothing affair, so you might wonder exactly how hot the shrimp were. As it turns out, the FDA’s report makes clear that the contamination was far below the legal threshold for Cs-137. In addition, not […]
Is it finally time to cue up the Bowie? Or was the NASA presser on Wednesday announcing new findings of potential Martian biosignatures from Perseverance just another in a long line of “We are not alone” teases that turn out to be false alarms? Time will tell, but from the peer-reviewed paper released simultaneously with […]
I’ve been flying quadcopters a fair bit lately, and trying to learn some new tricks also means crashing them, which inevitably means repairing them. Last weekend, I was working on some wiring that had gotten caught and ripped a pad off of the controller PCB. It wasn’t so bad, because there was a large SMT […]
Fresh hacks here! Get your fresh hot hacks right here! Elliot and Dan teamed up this week to go through every story published on our pages to find the best of the best, the cream of the crop, and serve them up hot and fresh for you. The news this week was all from space, […]
Two billion downloads per week. That’s the download totals for the NPM packages compromised in a supply-chain attack this week. Ninety-nine percent of the cloud depends on one of the packages, and one-in-ten cloud environments actually included malicious code as a result of the hack. Take a moment to ponder that. In a rough estimate, […]
Last time, we built a case for a PCB that handles 100 W of USB-C power, an old project that I’ve long been aiming to revive. It went well, and I’d like to believe you that the article will give you a much-needed easy-to-grasp FreeCAD introduction, Matrix knowledge upload style, having you designing stuff in […]
This week Jonathan and Dan chat with Frank Vasquez and Chris Simmonds about Embedded Linux, and the 4th edition of the Mastering Embedded Linux Programming book. How has this space changed in the last 20 years, and what’s the latest in Embedded Linux? Mastering Embedded Linux Development on Amazon https://2net.co.uk/ The Linux Plumbers Conference Call […]
Last time, I described how to write a simple Android app and get it talking to your code on Linux. So, of course, we need an example. Since I’ve been on something of a macropad kick lately, I decided to write a toolkit for building your own macropad using App Inventor and any sort of […]
There’s a saying in mine country, the kind that sometimes shows up on bumper stickers: “If it can’t be grown, it has to be mined.” Before mining can ever start, though, there has to be ore in the ground. In the last edition of this series, we learned what counts as ore (anything that can […]
