Wired has a fascinating story this week, about the length Sophos has gone to for the last 5 years, to track down a group of malicious but clever security researchers that were continually discovering vulnerabilities and then using those findings to attack real-world targets. Sophos believes this adversary to be overlapping Chinese groups known as […]
Out of curiosity, I redrew the Supercon Vectorscope badge schematics in KiCad last year. As you might suspect, going from PCB to schematic is opposite to the normal design flow of KiCad and most other PCB design tools. As a result, the schematics and PCB of the Vectorscope project were not really linked. I decided […]
This week, Jonathan Bennett and Dan Lynch chat with Josh Bressers, VP of Security at Anchore, and host of the Open Source Security and Hacker History podcasts. We talk security, SBOMs, and how Josh almost became a Sun fan instead of a Linux geek. – https://opensourcesecurity.io – https://hackerhistory.com – https://infosec.exchange/@joshbressers – https://anchore.com Did you know […]
Even in the advanced world of 2024, robots are still better in science fiction than in reality. Star Trek gave us the erudite and refined Data, Rogue One gave us the fierce yet funny K-2SO, and Big Hero 6 gave us the caring charmer named Baymax. All these robots had smarts, capability, and agency. More than that, though—they were […]
Problem solved? If the problem is supplying enough lithium to build batteries for all the electric vehicles that will be needed by 2030, then a new lithium deposit in Arkansas might be a resounding “Yes!” The discovery involves the Smackover Formation — and we’ll be honest here that half the reason we chose to feature […]
With the 2024 Hackaday Supercon looming large on the horizon, Editors Elliot Williams and Tom Nardi start this episode off by talking about this year’s badge and its focus on modular add-ons. From there they’ll go over the results of a particularly challenging installment of What’s that Sound?, discuss a promising DIY lathe that utilizes […]
Leading off the week is the controversy around the Linux kernel and an unexpected change in maintainership. The exact change was that over a dozen developers with ties to or employment by Russian entities were removed as maintainers. The unfortunate thing about this patch was that it was merged without any discussion or real explanation, […]
The Vectrex was a unique console from the early 1980s. Developed by a company you’ve probably never heard of—Smith Engineering—it was put into production by General Consumer Electronics, and later sold by Milton Bradley. It was an outright commercial failure, but it’s remembered for its sharp vector display and oddball form factor. The Vectrex was […]
This week Jonathan Bennett and David Ruggles chat with James Smith about Manyfold, the self-hosted 3D print digital asset manager that’s on the Fediverse! Does it do live renders? Does it slice? Listen to find out! https://floppy.org.uk/ https://manyfold.app https://github.com/manyfold3d/manyfold Did you know you can watch the live recording of the show Right on our YouTube […]
If you want to deliver the maximum power to a load — say from a transmitter to an antenna — then both the source and the load need to have the same impedance. In much of the radio communication world, that impedance happens to be 50Ω. But in the real world, your antenna may not […]
