Yes. x86 processors translate instructions to internal micro opcodes before scheduling or running them. Those look nothing like the x86 instructions.

It is partly historical notoriety. It allows one to prove certain statements that seem counter-intuitive. So proofs that employ it can often be viewed with some skepticism. Moreover, this axiom is _independent_ of the other axioms in ZFC. I

One of my highest-cited papers didn't pass peer-review. But that's okay. The citations (of the pre-print version) speak for themselves. If papers like these are good enough that new students entering the field use it as a ramp-up

I couldn't actually figure out how to opt out of third-party tracking. They say I have to visit my wireless account, but not sure where to from there.

Huh, for some reason I had just assumed that it must be open based on the buzz around it. Cool.

For the uninitiated, WTH does semi-public mean? Did GPT-3 only provide an API but not the model?

Hmm. You're right, not if we are restricting ourselves to rectangles. But if we make A u-shaped, with B nestled in it, we'll be in business!

If they have customers who need that kind of database, I'm sure they will be willing to help out with the testing. The setup doesn't have to be too crazy. Storage appliances with 20-30 hard drives are fairly common, actually. Even

It does, in that it's much easier for me sign up with a throwaway username. It's also part of the reason HN doesn't require these SSO integrations.

The material nature of hardware is barely any higher than that of software. Yes, you cannot just copy bits around, but you can take the same design and fabricate millions of chips for pennies. The cost of production for any given chip of Si

I haven't looked at your past blogs, but it certainly sounds like you are making perfection the enemy of good. Your blogs don't have to be perfect, it just needs to be better than the current state, while not causing unanticipated

People generally expect equality to produce either true or false. Not a tri-value pair. That interpretation makes sense to me when I read the docs, but is way too easy to miss when I'm actually doing comparisons.

by lopsidedBrain 6y ago
The comparison is fair because it tries to automate expertise. I'm sure you know exactly how much of which filter to apply for similar results. Laymen like ourselves will need a lot more trial and error. Their contribution here is to p

I work in exactly two modes of `gcc` usage. I either accept `./a.out` as the name I deserve, or I write a `CMakeLists.txt`. There nothing in between.

My trick has always been to rely on tab auto-completion. mv foo-<tab> mv foo-bar-baz foo-<tab> mv foo-bar-baz foo-bar-baz Now I can edit the second part pretty quickly. Downside: you have to at least type `foo-`

> Why is storage necessary? Have you ever tried wiring any non-trivial logic without flip-flops? Say, a simple signal routing layer. Even the most basic bits of logic becomes much less efficient to downright impossible without storage.

That is sounds more appropriate for either terminating the program or resumable exceptions like division by zero. In languages with a try-catch construct (specially C++), the complexity of implementing exceptions has to do with stack unwin

Pretty much every successful open source project that people pay attention to is one that has had long-term support behind it. Linux, Mozilla, gcc, clang, git. Almost always, that support begins with the original author. Protects that don&#

I can't speak for the toolchain maintainers. But with appropriate flags to force or skip those passes, yes I can see something like this being merged in.

GCC does this too fwiw. Whether or not it is considered a bug, it doesn't have one particular root cause. Several common optimization passes assume small function body. Since functions are typically small, many optimizations use this a

The part you quoted does not talk about buggy code. Bugs will always exist, the idea is to prepare for them. Migrate systems incrementally, run versions in parallel, have tested rollback strategies at every step, so on and so forth. Not cut
