   Hi, I made this. This shouldn't be on HN yet. It's not quite ready for that.

   I don't think builtin compression is necessary, but it would be better if the CLI supported it similarly to tar. Compressing a 57.5 MB .hop archive with `gzip -c` returns an 11.7 MB file. This is a similar compression ratio as tar -&gt

   Offsets and lengths are stored as unsigned 32 bit integers. This saves space/memory, but means it won’t work for anything bigger than 4 GB Maybe that’s overly conservative. Wouldn’t be hard to change

   Good idea, worried a little about impact to serialization/deserialization time though. Maybe could still store it as a flat array

   Hop reduces the number of syscalls necessary to both read and check for the existence of multiple files nested within a shared parent directory. You read from one file to get all the information you need instead of reading from N files and

   The numbers shown are with zip -0, which disables compression.

    What do you think of NURBS? eg http://verbnurbs.com/ . It’s intended for 3D instead of 2D, but still kind of relevant How do you plan on doing text rendering? I feel like that’s often a challenge with cross-platform UI frame

    I globally import this via usingnamespace: pub const string = []const u8; This lets me do: &[_]string{“hi”} A little better, but not great.

    Running the benchmarks locally (zig is fastest, but that's probably expected) zig (~1 week older than HEAD): ./zig-out/bin/qsort filling shuffling running took 177.46ms rust nightly: cargo

    I’ve been using Zig for a new JavaScript build tool and I really like it. It’s great for writing performance-critical code. It took me about two weeks to feel comfortable & productive in it.

    If you look near the end of the line for each result, that % value is the margin of error. > readFileP x 2,182 ops/sec ±4.00% (67 runs sampled) This means readFileP took between 2,094 and 2,270 ops/second. > fs.readFile x 2

    I agree in principle, but for some reason, the underlying implementation for fs.promises is completely separate. I think this is where fs.promises.readFile reads the actual file https://github.com/nodejs/node/blob&

    just.js (#9) looks interesting https://github.com/just-js/just It seems to be a much tinier JavaScript runtime than Node.js (still using v8), but linux only The benchmark is probably unrealistically optimized code but

    Turns out this was a bug – it wasn't properly adding `--wait` when opening the editor. Its fixed in 1.1.15.

    It works with non GitHub repos, but it’s not as fast. When it detects a GitHub link, it downloads the tarball from GitHub & and separately downloads the specific file linked (or the readme) using JSDelivr as a CDN. This is much faster t

    Author here — this is actually not a bug, but a deliberate design decision (so long as you meant, when the editor closes). I’m sorry for the confusion. git peek is not a faster alternative to git clone. It’s for quickly reading other peopl

    A different kind of tab-based filesystem that would be nice: Expose all the resources used in each tab in a virtual filesystem (JS, CSS, images, HTML, fonts, etc) in a folder for each tab. Basically Chrome Developer Tool's Sources tab
