That's a great idea, I should do that. There is another team that does something similar but everyone complains about it (it's not as good as your template).

This is a huge pet peeve of mine. At work I'm an expert on part of the code base that sees a fair number of contributions.I get many private IMs from colleagues asking me to "Approve please" or something like that with a dump

Fortran is pretty great: * First-class tensor manipulations (like numpy but in the core language) * Fast math with the right compiler * Automatically sized multi dimensional arrays on the stack * Zero cost C interop * Minimal runtime, no GC

It's more like hiring a personal assistant who is expected to work all the time quickly and unsupervised, won't learn on the job, has shockingly good language skills but the critical thinking skills of a toddler.

The trickiest problems with VT aren't due to mutability. Mutability is problematic with any kind of concurrent programs. The difficult problems are execution problems like pinning. There are plenty of existing concurrency libraries on

It's really not hard to reproduce, - vt1 locks lock1 - vt1 suspends on lock2 - n VTs attempt to initialize a singleton that requires lock1, so they all suspend within pinning class init. - you release lock2. - all platform threads are

We've been looking at virtual threads in a project at work and what we found is that it is quite difficult to adapt existing code to run with virtual threads. For example, class initialization pins a thread so any singleton defined in

I was that teenager and I still think Perl is very neat but I don't think I can write it anymore without lots of doc reading.

Did Forth inspire the stack-based VMs of python and java? I don't know about that part of CS history well, but a very large proportion of all code runs on stack based byte code interpreters.

Didn't they take their array programming from Fortran? The Fortran, numpy and matlab array syntaxes are basically identical, down to broadcasting and reduction rules.

We don’t have em dashes as punctuation in French —- commas are usually used instead —- so we get overly excited about using them when we can —- everybody likes novelty.

I think the jury is still out on Uber. They first became profitable in 2023 after 15 years of massive losses. They still burned way more money than they ever made.

My guess is that it doesn’t work for several reasons. While we have millions of LOCs to train models on, we don’t have that for ASTs. Also, except for LISP and some macro supporting languages, the AST is not usually stable at all (it’s an i

Languages that choose to fix this problem at the hash code level have hash codes that are still deterministic within a given program execution. They are not deterministic between executions, cf https://docs.python.org/3&#x2F

Lists aren’t copied on prepend. Tries (like scala’s Vector) or trie maps (the core map types of Scala, Clojure and probably Haskell?) aren’t copied on updates. In fact, whether a data structure is an immutable or persistent data structure o

You could do like a captcha but for computers. Here are some molecule, find the ground state geometry of all of them. You give some you already solved just to root out whether the solver is actually solving or faking it.

I was under the impression that the bad crawlers exist because it's cheaper to reload the data all the time than to cache it somewhere. If this changes the cost balance, those companies might decide to download only once instead of ove

C++ is (according to Bjarne Stroustrup) a general purpose programming language that can be used to build general business software and applications with, not just a systems PL. This is why perf is all over the place —- the core language is

C compilers are just too smart IMO to make C portable assembly. Your example doesn’t always ADDI either, for example if it is inlined https://godbolt.org/z/vv9rvKsxn This isn’t qualitatively different from what the JVM

They aren’t equally expensive everywhere. They are cheap on the JVM.

The parent example can be made clearer like this: https://godbolt.org/z/MKWbz9W16 Dead code elimination only works here because integer overflow is UB.

I'm not sure you understood the article. You can have a very low load but each task on your queue takes a while to process, in which case you want fair distribution of work.
