Having to do a load to get the metadata is probably why. Say you have a big array of strings and you care about the compactness of that array for cache reasons, so making the string structs small matters. You probably want to do some operat

I was mainly responding to the claim that these black boxes produce a hypothesis that is useful as a basis for scientific theories. I don’t think it does, because it offers no explanation as to the how and why, which is as we agree the prim

Fair. I guess the interesting thing for protein folding research then is that there appears to be a way to approximate/simplify the calculations required to predict folding patterns that doesn’t require the precision of existing foldin

There is an issue scientifically. I think this point was expressed by Feynman: the goal of scientific theories isn’t just to make better predictions, it’s to inform us about how and why the world works. Many ancient civilizations could accu

At one point I bought a bunch of pens from jetpens because I wanted to find “the best pen” (for me at least). I bought like 10 different kinds, some of which were I think exclusive to Japanese markets, some ballpoints, some gel rollers, etc

It basically never should unless the inliner made a terrible judgement. Devirtualizing in C++ can remove 3 levels of pointer chasing, all of which could be cache misses. Many optimizations in modern compilers require the context of the func

Seems like inspecting the JVM byte code for errors would be the next step.

GDB can kind of do this, you can have commands fire when a breakpoint is hit and continue automatically, and if you want to take it further you can use Python and execute Python code to inspect the state of the CPU and memory in some progra

I don’t think any of the proposals by AI x-risk people are actionable or even desirable. Comparing AI to nukes is a bad analogy for a few reasons. Nukes are pretty useless unless you’re a nation state wanting to deter other nations from in

I think Bell’s inequality implies the state can’t be deterministic but hidden. I’m not sure how you could evaluate the “quality” of the randomness, or if there are existing results analyzing this.

AdGuard is useful on iOS because of how limited browsers are on it. They also provide a DNS adblocking service which for someone less technical who can’t setup a pihole is a useful service.

It is much easier to locate someone (physically) transmitting RF signals illegally than someone using a VPN illegally.

I agree that tech companies have nonexistent support because they refuse to hire people to do it, but the DMCA is a terrible law and enables people to do this way too easily. It should cost money (or something) to file a DMCA claim to preve

There’s probably a way to make an analog AI chip programmable, but yeah the wiring (model architecture) is fixed when you fabricate/design the circuit. I think we’ll start to see simple models deployed to edge devices soon where low po

My understanding is that this doesn’t work for back propagation because it needs to know the forward pass computation exactly to adjust the weights. Analog computation introduces error in the form of noise (thermal, environmental, etc) whic

This is pretty much my issue with this article. By its criteria assembly isn’t low level, which makes the claim pretty uninteresting. You could argue there are/were processors that had low level ISAs (VLIW, no OoO exec, no memory reord

This seems like a silly point to make. It’s still an emerging technology, and will ultimately be the end-all-be-all technology if humanity can solve AGI. Even if we don’t any time soon specialized models will certainly provide massive produ

Aren’t there analytical solutions to stoplight scheduling? Or do they make inaccurate assumptions about traffic when used in practice?

With GCC/clang you can write an ASSERT/ASSUME macro that does this. Basically: if (!cond) __builtin_unreachable();

Yeah but presumably they won’t let you fast forward ads. AFAIK Twitch already does this, I’m surprised YouTube hasn’t.

Turns out there is! __builtin_launder seems mostly equivalent to what the author proposes but probably more reliable. Facebook’s folly library appears to use both, preferring the builtin.

I feel like there should be a builtin that takes a void* and returns a void* which basically marks the input as aliased by the returned pointer regardless of the TBAA rules.

It’s because frequency range for MoCA overlaps with the upper frequencies of DOCSIS3.1. The modem was probably receiving/transmitting in the MoCA range and that data looked like junk. Installing a PoE filter at the modem prevents both

The minimum standard required to graduate public high school in the US is abysmally low. You can probably get through some schools without ever showing up because the teachers and administrators don’t want to deal with you. They are incenti

It’s arguable whether public schools provide positive socialization in the first place. I imagine it largely depends on the school, the teachers, the other students, and the individual, but plenty of people come out of public school with po
