First thing I did was take a bunch of photos. One of the things that had meaning wasn't the individual items, but the assemblage of the whole: the choices made in the arrangement of tools in the workshop, projects being worked on, th

A casual Google search will turn up evidence. Just one example of many: Uyghur workers, complete with police guards, are being supplied to factories throughout China. "Another new advertisement claimed to be able to supply 1,000 Uyghur

That's an English billion (10^12), given that there are a million square metres to the square km? Mind you, I wouldn't want to be standing within 18m of where it lands, so either definition of "billion" does make sense.

The earth emits about 230W/m^2 in infrared [1] (compare with 1000W/m^2 for solar flux), so it's potentially an idea worth pursuing. This group has posted several records for solar cell efficiency, so they generally know what

I'm guessing the real cause is an aged electrolytic capacitor. The electrolyte can dry out over time causing a change in capacitance. Power supplies are the most common failure in electronics and electrolytic capacitors are a common

I've skied Kosciuszko, after about 3 days of beginner lessons. I've also mountain biked it (up and down, as we we were too cheap to pay for the lift). It's all the same route as it is in a national park, so there are limite

Technically there is no such thing as a continuous wave, as any signal of finite duration (time) must be composed of multiple frequencies, and all signals are of finite duration. This is closely related to the uncertainty principle in phys

The original study of the Bare-nosed wombat was produced by a 15 year old boy, Peter Nicholson, who in the 1960s used to sneak out of his boarding school dormitory of a night to crawl into wombat burrows and make friends with the wombats.

With my engineer's hat on, I can't disagree with you. There's an argument that open hardware suffers from an overdose of pragmatism, which is not unexpected given that we're mostly engineers. Some barriers will require

Try this book: "Understanding Digital Computers : A Self-learning Programmed Text That Will Teach You the Basics for the Microcomputer Revolution" by Forrest M. Mims III. It's dated, but the core material is still relevant.

Also the note at the bottom of that page: that they are doing away with AVX-512. A bit sad for those who need to squeeze maximum performance out of a CPU. (I gather it lives on in Xeon and Zen 4.)

By my understanding "casual blood pressure" is when you sit for 5 minutes in a doctor's office then have a blood pressure measurement taken [1]. "Ambulatory blood pressure" is when a monitor is strapped onto you an

I don't fully get the "lowers blood pressure" claim. Doesn't Table S2 in the paper say that blood pressure stayed roughly the same for people doing high-resistance IMST and went up for the control/sham group doing

A fairer comparison with swiping a credit card would be if you used the wallet like a credit card: just give it to the cashier, let them take out what is required and give it back to you.

Neat idea, though it's not a definitive test. In my experience a microwave oven cavity provides about 40dB attenuation, and it's possible to maintain an LTE connection with that sort of path loss. Hint: If you're ever doing
