Looks like @VirginMediaIE in Dublin doesn't work in Dublin starting from Sunday. Does anyone know any details, because I am unable to receive any updates or information about it, neither from the office nor from the support team? My three SIMs are offline totally

Today I learned about `git commit --fixup=<commit>` and `git rebase --update-refs --autosquash -i <commit>` and my life has significantly improved. I fear no stacked PRs. Bring it.

I give you a list of integers... like 1, 4, 17, 40, 75... how do you quickly set the bits at the corresponding indexes?... e.g., build word (1<<1) | 1<<4) |... You can use AVX-512 or another other fancy ISA you want. Go!!! And share the answer with @geofflangdale

What's the known best method for "indexes to bits"? We have 0 to 64 indexes, in order, in the range [0..63]. e.g. AVX-512 register of 64x8b values and a mask to indicate which are valid. Output is 64b value where bits are true iff the bit number was in the indexes.

I just made llamafile 1.3x - 5x faster than llama.cpp on CPU for many prompt / image evaluation use cases and hardware. justine.lol/matmul/

Terminal flamegraph tools feel under-appreciated. My default flow used to be: record a profile, scp it off my server, <input type="file" /> upload it into some website, click to generate. TUI flamegraph tools are much simpler! For perf: github.com/4rtzel/tfg. For go pprof: github.com/laixintao/flamesh….

I'm curios, do people care about avx without avx2? I heard that PS4 had avx but not avx2, also couldn't confirm via google. What is your expirience? #simd

Need `array_proxy` help. I have a container where iterator returns pair<int, int>. Unfortunately there is code that does `auto& x = it->second`. I know that std::views::zip doesn't have an `operator->` but that's not ideal for me. Is there a way? godbolt.org/z/nb6EhczE5

My SWAR code for single-character search within a string is __slower__ than the `std::string::find`. That’s not true for the 2-character, 3-character, or 4-character long needles. Anything else I’m missing here? github.com/ashvardanian/Stri…

Docker vs. containerd vs. Podman 🧵 Containers are everywhere, and Docker is the most popular (and user-friendly) way of running them. But it's definitely not the only way! I prepared a series of exercises to help you explore the alternative single-host runtimes 👇

I wouldn't recommend to use official meson support in CLion 2023.3 or CLion Nova. Better to use legacy way by opening compilation database in IDE. Legacy way is still much more friendly and it has less errors. #meson #clion #jetbrains
