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 […]
Two weeks ago, it was holographic cops. This week, it’s humanoid robot doctors. Or is it? We’re pretty sure it’s not, as MediBot, supposedly a $10,000 medical robot from Tesla, appears to be completely made up. Aside from the one story we came across, we can’t find any other references to it, which we think […]
Thunderstorms were raging across southern Germany as Elliot Williams was joined by Jenny List for this week’s podcast. The deluge outside didn’t stop the hacks coming though, and we’ve got a healthy smorgasbord for you to snack from. There’s the cutest ever data cassette recorder taking a tiny Olympus dictation machine and re-engineering it with […]
Something rather significant happened on the Internet back in May, and it seems that someone only noticed it on September 3rd. [Youfu Zhang] dropped a note on one of the Mozilla security mailing lists, pointing out that there was a certificate issued by Fina for 1.1.1.1. That IP address may sound familiar, and you may […]
A few years ago, I bought an 8 mm home movie camera in a second hand store. I did a teardown on it here and pulled out for your pleasure those parts of it which I considered interesting. My vague plan was to put a Raspberry Pi in it, but instead it provided a gateway […]
