Custom-built keyboards are very cool, but I will never understand putting all this love into a non-ergonomic design. Typing on something with no separation or tilt murders your wrists! Mechanical keyboard enthusiasts will spend ages refinin

Per your chart, single-thread performance has been basically flat since 2012. There's also negligible difference between SATA and NVME SSDs for regular desktop work (there are many videos demonstrating this). I have a six-year-old comp

Take a look at this story, where covid-positive hairdressers interacted with over a hundred clients (all involved wearing masks) without infecting any of them: https://www.cdc.gov/mmwr/volumes/69/wr/mm692

Yes, this has also helped me (at one point my wrists were bad enough I had to start mousing with my non-dominant hand). It seems like pulling exercises such as deadlifts or pull-ups or just rock climbing in general help the most.

Currently I use the Microsoft Natural Ergonomic Keyboard 4000, an enormous dinosaur which can reliably be bought for $20 used. I had the Microsoft Sculpt keyboard for a few years before that, which I liked, but the build quality was very ba

The three most impactful things you can do to avoid wrist injuries are: (1) Ensuring your chair, desk, and keyboard are set up so your wrists are straight when typing (2) Using a split/tilted keyboard so your wrists do not need to rota

There are only a couple competitors that are split, ortholinear, and mechanical (ergodox and some small custom others). They all charge over $300 afaik. You can get decent split/standard/membrane keyboards for $80-120 from goldtou

I've been getting deep into the home office ergonomics hole now that I'll be working from home indefinitely. There's a real danger here - I generally pride myself as someone who is conscientious of consumerist tendencies, but

Israel is an extension of American interests in the Middle East, an esteemed member of the empire. Palestine is, among other things, used as a test lab for riot control tactics & equipment [0]. Maybe you're from the UK where it

The system can of course continue to grind & lurch for a very long period of time. However, here we have a global forcing function: climate change, and the likely mass refugee crisis. America is not set up politically to welcome those r

Well, you can't rewrite anything in TLA+. It's a formal specification language, not verification language. So you usually use it to catch spec- or algorithm-level logic & concurrency bugs then manually write the code to corres

Quantum computers are modeled with extremely basic linear algebra. Quantum states are vectors and gates are matrices which multiply those vectors to get new vectors. How much simpler do you want? You can explain most of it as rotations arou
