I was laid off in October after 13 years at Amazon and am still seeking a new opportunity. Please ping me if you know of a full-time remote role working on network and/or infrastructure security (on-prem and cloud-based). I also have experience with embedded/OT/IoT network security and wireless security. After hours I run a small network (AS46577) and fiddle with microcontrollers, embedded Linux, ham radio, and drones. Boosts appreciated. #infosecjobs #getfedihired #jobhunt #jobsearch

Please pick up ham radio. (Just a useful skill.)

@Gargron @scott recent enough Mastodon also pops an OPEN link to the thing you just posted after posting, in the bottom left (at least if you're using the multicolumn layout). After that, you can just keep the started thread open and reply to the last post in it as you go.

Rare-Earth-Free Magnets With High Entropy Borides
Map of the calculated magnetic anisotropy. (Credit: Beeson et al., Adv. Mat., 2025)
Although most of us simultaneously accept the premise that magnets are quite literally everywhere and that few people know how they work, a major problem with magnets today is that they tend to rely on so-called rare-earth elements. Although firmly in the top 5 of misnomers, these abundant elements are hard to mine and isolate, which means that finding alternatives to their use is much desired. Fortunately the field of high entropy alloys (HEAs) offers hope here, with [Beeson] and colleagues recently demonstrating a rare-earth-free material that could be used for magnets.Although many materials can be magnetic, to make a good magnet you need the material in question to be both magnetically anisotropic and posses a clear easy axis. This basically means a material that has strong preferential magnetic directions, with the easy axis being the orientation which is the most energetically favorable.
Through experimental validation with magnetic coercion it was determined that of the tested boride films, the (FeCoNiMn)2B variant with a specific deposition order showed the strongest anisotropy. What is interesting in this study is how much the way that the elements are added and in which way determines the final properties of the boride, which is one of the reasons why HEAs are such a hot topic of research currently.
Of course, this is just an early proof-of-concept, but it shows the promise of HEAs when it comes to replacing other types of anisotropic materials, in particular where – as noted in the paper – normally rare-earths are added to gain the properties that these researchers achieved without these elements being required.

At the end of the day, Linux is the worst operating system that has yet been developed, except for all of the other operating systems. And it's still unusably bad on some basic levels. One day, I believe, we will have good computer systems. But I may not live to see them.

Linux? Pah! All the power of the digital world at your fingertips and... it can't hibernate properly.
macOS? This dude won't even let me install whatever programs I want without a whole song and dance routine. Is this a general purpose computer or a little etch a sketch for kids?
Windows? Don't even get me started on this spyware crap that's holding multiple industries hostage. After the revolution, no one will even want to use windows.

I'm a woke centrist, I use macOS, linux, and windows. And all of them irritate me for different reasons!
