+1. AGPL demonstrates excellent forward thinking. We need more AGPL software.

Yes, they are making themselves vulnerable to disruption in the mid-term. Short-term, they are still golden.

Not to defeat your point, but $0.42/watt is considered a bit too expensive nowadays (unless, it includes shipping). The regular price for monocrystalline silicon solar panels is around $0.21/watt on Alibaba ([1]), not including sh

USSR had multiple classes (despite being a classless society on paper). Nomenklatura ([1]) and some other smaller classes had access to western press and were often allowed to travel to the "capitalist countries". Even at home, th

As other commenter said, the magic happens not just between photons, but between photons and non-linear optical materials, in which these photons travel. While not directly related to computing, I was fascinated to learn that lasers routine

The magic of JLCPCB is that they can do SMT mounting quickly, cheaply and for as low as 3-5 boards. My standard iteration time is about 8 days (which includes shipping from Shenzhen to SF Bay Area) and it liberates me from a need running an

Got it, thanks. Btw, have you followed their SMT Assembly service offering? I've assembled 40+ designs with them this year, and it does seem like they do it on their own instead of delegating. Nobody comes close to their prices and ass

Nice catch about one of the company being bankrupt. I've taken a deeper look at Lyten and it does not seem to be a savior here either: 1. They need to produce graphene at scale and they don't yet have a solid plan to do that. 2. L

If we speak about what's available in laboratories, Lithium–sulfur battery gives around 550 Wh/kg with up to 1500 charge-discharge cycles ([1]). Not available commercially, but there are a few companies that try to commercialize t

If your goal is to pass a certain message publicly, then the injection is an attack to your goal. These injections often completely broke functionality of any even slightly non-standard blog engines, as they were not tested by the designers

Thank you. My memory lied to me. I stand corrected, although the reason to include Angela to the list is now physical chemistry. :)

Some ISPs inject their own ads on non-encrypted pages. It was a prevalent practice in Russia as early as 2007-2010. Not sure if it's true for other countries and modern times, but the technical point is still valid: by using HTTPS, thi

True. It's also very cheap to add that functionality, since GPS breakouts that can be accessed via UART can be bought on Ebay for as cheap as $11: https://www.ebay.com/itm/363562034686

From what I understand, it's a play around the Amazon Inventory Storage fees ([1], [2]), which normally are $0.75 per cubic foot monthly, but grow to $6.90 per cubic foot, if stored for more than a year and not sold. It's possible

For someone like me who is familiar with JAX, but only recently starting to consider to pay attention to Julia (it does have a momentum), would it be possible to provide any good examples of using GPU / multiple GPUs from Julia? I&#x27

From the post: > JAX on GPU outperforms everything I've only skimmed through the blog post, but it feels that the GPU acceleration without a need to write any custom code, was the primary reason to choose JAX.

Thank you. This is exactly the mistake I made. It raised some flags in my head when I read it, but then again - Romans did so many things out of lead that I did not challenge it.

Quicksort is actually possible; it's really simple. What really would tick the box is Timsort: https://en.wikipedia.org/wiki/Timsort

by krasin 5y ago
Good point. I somehow was thinking about metal springs (Romans used springs from lead, for instance), but there's no reason to restrict it to metal.

Springs could be used instead of rubber bands. While "coil spring" is a relatively modern invention, other kinds of springs are known from the Bronze Age, accoding to https://www.designingbuildings.co.uk/wiki/
