Hint for authors: when discussing linear algebra (or really most other kinds of math), follow normal conventions. In this case, the convention would be that - (the minus sign) means subtraction. It does not mean "and also", espe

For most purposes, I would avoid the shunt and use a current transformer (for AC) or a DC current sensor (conceptually the same thing but with a Hall effect sensor or other mechanism that works for DC). This way you don’t need anything to

If you want to entertain yourself and you have a car that has a distinct start action (so a real ICE or some hybrids), you can do an easy experiment. Get in the car while it’s off. Press the brake pedal down, fairly firmly, release it, and

Many cars (especially ICE cars) may not have operational brake boost when you first get in to them — the vacuum that the power brakes rely on can easily be gone. So you step on the brakes without assist, then you start the engine, and then

This is a piece of cake using GitHub’s excellent permission system. (I’m joking, of course. Service accounts are nowhere to be seen. OAuth can’t even scope to an organization , let alone a repository. And this whole github.dev thing illus

It sounds like the Loop, as it currently exists, is not actually able to do any of the above. It can take you from an unpleasant “station” to another one. This limitation isn’t fundamental, but it is still a limitation of the system as bui

Hah, you read more of it than I did :) I’m willing to believe that there is some other code path that thinks that a path like "a/../b" is not allowable, and Claude saw that and wanted to enforce it, and then forgot abou

This is kind of a sad situation. Tridge is an excellect programmer and a very respected member of the community, and I totally get it. rsync, like most old C projects, has a lot of accumulated cruft, and things that would be nice to fix,

Worse: go look at the MMSE. I bet that, at least for patients with reasonably functional memory, taking the MMSE and then taking it again a few weeks later from the same examiner will tend to improve the score the second time.

The fact that xlock crashing unlocks an X11 session is, IMO, pathetic.

Go find some class action settlements. There’s a good chance the total damages (substantially) less than the profits from whatever behavior generated the lawsuit, and that’s not even accounting for interest. So, no.

Right. And IMO it works poorly. It’s extremely common to see a settlement such that the company still ends up ahead on its problematic behavior.

IMO it would be better if there was a general mechanism to prevent profiting from corrupt business practices. For example, a court could determine how much money Microsoft made by selling perpetual licenses that turned out to be a lie, add

I find myself wondering whether AMD has made some absurd high-level error like treating the Vivado as a separate business division with its own expenses and revenue and expecting it to be profitable. One thing that AI is not about to solve

Just a quick reminder: > This causes problems for signed data if you ever want to do things like compression since you need to know the exact bytes that were signed. If you are verifying a signature by taking some logical data structure,

You’re making a fascinating assumption that the tax authorities’ systems are at all integrated with the Secretary of State systems.

How useful is speculative decoding in a batched setting where you get paid for throughput (aggregated across users) and you mostly don’t get paid for latency or single-session throughput?

It’s also fraught because schools will spend increasingly large fractions of the time preparing kids for tests instead of teaching them anything.

You must be using only lame languages like C or Go or Python that aren’t optimized for laptop warming during compilation. Try using a Real Language with a Real Compiler, like C++ or Rust or Swift, and build decent-sized projects using all

True. But methyl isocyanate has the regrettable property that it was quite useful, to the point that there was a crappy, poorly maintained factory with tanks of it on site, with extraordinarily regrettable results. https://en.wi

I think you're missing my point. A sewage treatment plant may or may not be stinky, but I very much want to live in range of one so that my sewage gets treated. Similarly, living near a railway line means I can ride the train. Livin

Yes, absolutely, but it will depend on where one is, the surrounding geography, etc. A hairdryer pointed at me from 1m away running 24/7 will make me notably warmer. A hairdryer 20m away is probably unnoticeable. A 1GW datacenter is

I’m sure there is real data and real math available. For heating: imagine a 1km^2 campus. That’s 1e6 m^2, and peak daylight is around 1kW/m^2. So peak daylight on the campus is about 1GW. (Wow, just covering the whole campus with so

To me, datacenters, especially for AI (which tolerates an extra hundred ms of latency quite well) seem like an unusual form of development. Many forms of development have similar downsides: they destroy green space, they can be noisy, they

Got a source for that? I searched a bit and found so evidence that its combustion products are notably hazardous. I did find an SDS stating that MMA’s combustion products do not have special hazards.

MMA can apparently cause some issues that are more subtle than death. I would MUCH rather eat 1g of vitamin C than 1g of MMA. Also, vitamin C is not volatile, so there is no risk of inhaling it as a gas.
