Bumping the major version for fun is actually a pain, since configure scripts set upperbounds on major versions to be future-proof, anticipating breaking changes. Now it's just another edge case to deal with, and old versions of curl-d

Not the same... you need: `-S` to print error messages and `-f` to return exit code on non-200 responses. Also, --no-clobber is very recent (v7.83), so unlikely to work in general. So `curl -fLOsS ...`

Another point that I don't think gets emphasized a lot is that research software developers use spack as a dev tool on their laptop/cluster. Setting up easybuild locally is too much effort? If developers maintain spack recipes bec

The package definitions are quite declarative even though the language is imperative, see an example here [1]. For hashes, Spack uses the normalized (comments, whitespace etc removed) abstract syntax tree. With Spack it's easier to con

It doesn't have it, but what sort of undo do you think of? Undo the latest installation on disk? Roll back to the previous environment?

You still need both `needs: ...` and `stage: ...` > In GitLab 14.0 and older, you can only refer to jobs in earlier stages. > In GitLab 14.1 and later you can refer to jobs in the same stage as the job you are configuring. Why bother

- Github Action's design is much better, just look at [1] for example, there's a lot of low-hanging fruit in Gitlab that's not done for some reason - I've had tons of issues with their kubernetes runners, hard to debug s

Sometimes you can do this in two instructions per 16 / 32 / 64 chars (sse / avx / avx-512 resp): shuffle & compare. The gist of it is lookup[hash(char)] == char where 'lookup[hash(char)]' correspon

It's also a great way to spread misinformation if the paper has issues. This post goes viral, but news about it getting retracted won't. The article shouldn't refer to it as "published in December". It should say th

They say published, and link to a pre-print. It's not peer reviewed.

I've had too many issues trying to (recursively) reset all submodules after switching branches and cloning. Once submodules get in a limbo state it's a massive pain to get back to normal.

Is there an infinite recursion in /tmp? Do you use a bubblewrap-like pivot_root trick?

A few more CVEs and we're at OpenSSL 1.1.1z, followed by v1.1.1.za, and it is going to break some package manager that in a certain locale orders versions as 1.1.1.za > 1.1.1z, and its users will be stuck on a vulnerable version.

Do you have references for this? My understanding is that low heart rate training is still standard for elite endurance athletes.

I wonder if this bug in logic (instead of buffer overflows) would also have been less likely in a different language. Would it have been more obvious in a language where it's easier to work with dynamically allocated arrays and strin

Aren't C++ compilers also interpreters for large subsets of the language, all the template / constexpr / consteval stuff ;)

If you have a slow filesystem and you’re compiling C, make has a “lot” of overhead due to implicit rules. There are many more rules than you write, unless you set stuff like .SUFFIXES: to nothing

Do note that GNU make is still being developed. It even had breaking changes in the recent 4.4 release. Also GNU make 4.3 has at least one bug (e.g. on Ubuntu 22.04) where tgt: gcc hello errors when you have a directory wit

The downside of C++ is that exceptions can come from any possible function call depth, whereas in C you only have to deal with error return codes. So in that sense it’s easier to deal with errors in C, and harder to test the error paths in

You can have RAII with GCC extensions in C: char *buf __attribute__ ((__cleanup__(free_buf))) = malloc(1024); This calls free_buf(buf) when buf goes out of scope. I’ve actually seen projects use it in the wild to close files or free memory

I wonder to what extent compilers even emit avx512 instructions apart from the common ones (load, store, shuffle, arithmetic) in case you don’t want to manually optimize for sse / avx / avx2 / avx512.

They should put energy labels on programming languages. It’s convenient to use Python, but a waste of cpu cycles
