I would love to see a space and comment preserving json parser. Being able to programmatically update a config file without losing formatting and such sounds like a big win.

A quick sanity check is that there aren't many solar-powered flying creatures. A 15W solar panel is about three square feet, and probably weighs several pounds. A 15W quadcoptor is about two square feet and has a takeoff weight of less

> one thing desperately missing is a free GPU. I wonder if the Larrabee approach would work here: many simple RISC-V cores running in parallel, with wide vector units and a little specialized hardware (eg texture sampling).

It's a country where only top level officials have access to the internet, most places don't have working electricity, and there's virtually no interaction with the rest of the world.

North Korea doesn't exactly have a large pool of technically skilled people available.

Do you have a link to info about that kernel/userspace incompatibility? I thought Linus' mantra was "we don't break userspace".

The restriction is because commercial activities are prohibited over amateur radio, and encrypted traffic would prevent that rule from being enforced. I believe there's an exception for controlling remote devices when you need to make

Yes, there are large difficulties to creating reversible computers in practice. However, it's the theoretical benefits (such as no minimum power dissipation) that motivate people to work on them.

Reversible computers are turing-complete. The only requirement is you either have to store all intermediate results (no erasing), or you have to periodically "uncompute" them. I don't remember what the minimum bound on the ov

2. Reversible operations have no minimum amount of energy that must be dissipated as heat, unlike irreversible operations which must dissipate every time bits are erased. So each computer individually could be consuming no energy, so both t

The benefit of a reversible computer is that there is no minimum amount of energy it must dissipate as heat in order to perform its computations. Every time a bit of information is erased, a certain amount of energy must be dissipated as he

If you had a "sufficiently smart compiler" you wouldn't need register renaming and instruction reordering, but such a compiler has consistently failed to appear. That's a big part of the whole Itanium fiasco. If you want

Back in the 80s, instruction decode was a large part of the logic in a CPU (thus the motivation for RISC). Currently, it's a tiny fraction. It's been many years since a simpler instruction set was useful for reducing the complexit

How is bare-metal coding on something like the beagleboard black? Does it have the same issues, or is it a more open platform?

I would attribute that more to Intel's revenue than anything special about the company though.

Where does that number come from? One data center * 24 backup generators * 3 MW each = 72 MW per data center. Four of those = 288 MW > 1/4GW. Google has more than three data centers.

The prototype kilogram was made of platinum-iridium because they are very nonreactive and fairly hard, so once the prototype was made it would be unlikely to be accidentally modified. If you tried to use water ice as a standard, you'd

I wonder if you could incorporate a wire mesh into the zeolite to improve the heat distribution.

I'm glad I saw this, because I didn't have an email or password set up. In the future, when a major feature like this is removed, it would be nice to see a banner across the top for people who will be affected.

Good point, but you could have as many swear words as you want in your page content.

As far as I know, there was never any registrar who insisted on approving your site's content before they would give you a DNS entry. Even if there was, there were many other places you could register that didn't.
