How I Doubled My Lookup Performance with a Bitwise Trick
https://www.reddit.com/r/programming/comments/1m0tcd6/how_i_doubled_my_lookup_performance_with_a/
<!-- SC_OFF -->Hey folks, While working on a Cuckoo Filter implementation, I originally used a simple byte array to store 4-slot buckets, each holding 1-byte fingerprints. Then it hit me—those 4 bytes fit perfectly into a 32-bit integer. So why not treat the whole bucket as a single uint? That small insight led to a few evenings of playing with bitwise operations. Eventually, I replaced loops and branching with a compact SWAR (https://en.wikipedia.org/wiki/SWAR). Here's what it is in one line: ((bucket ^ (fp * 0x01010101U)) - 0x01010101U) & ~(bucket ^ (fp * 0x01010101U)) & 0x80808080U) != 0 Over 60% faster positive lookups and more than 2× faster negative lookups. I liked the result enough to write up the whole journey in an article: the idea, the math, step-by-step explanation, and the benchmarks. If that one-liner looks scary, don't worry—it's not as bad as it seems. And it was fun stuff to explore. <!-- SC_ON --> submitted by /u/axel-user (https://www.reddit.com/user/axel-user)

LOON v1.0 - a modular language that compiles to JSON
https://www.reddit.com/r/programming/comments/1m1rybf/loon_v10_a_modular_language_that_compiles_to_json/
<!-- SC_OFF -->I know i already posted about this on this reddit, however, the version i posted not only was a pre-release, but it was also unpolished and still in an experimental phase. "But what is LOON?" LOON, short for Label Oriented Object Notation, is a language for structuring data in a modular way. Unlike languages like YAML, it features value referencing, reusable code, file imports and a compiler to JSON. "Ok, but what does this do? Like how does this help me?" It doesn't have to help you, this a passion driven project, none of this was made to solve, but rather to make something for: - Me: for learning Others: as a thing i like to showcase "But, in a hypothetical universe where this has a real use, where would i use it?" Well, since it compiles to JSON, you can use it for file configs, building APIs and webapps, so all the tools that you already use in Javascript don't need to change, you just need the compiler. "So... that's it?" Yeah! And if you like it you can star the repo ^ Have a great time! <!-- SC_ON --> submitted by /u/PerformerDazzling601 (https://www.reddit.com/user/PerformerDazzling601)

Show: ggc – A terminal Git client with both CLI and interactive UI
https://www.reddit.com/r/programming/comments/1m1eiu1/show_ggc_a_terminal_git_client_with_both_cli_and/
<!-- SC_OFF -->Hi all, I recently built ggc (https://github.com/bmf-san/ggc), a Git client that runs entirely in the terminal — offering both traditional subcommands and a fuzzy-search-based interactive UI. It started as a personal need: my Git aliases and shell scripts were growing out of control. I wanted something fast, lightweight, and shareable. So I wrote it in Go. 🔹 Highlights: - Run ggc to launch an interactive Git UI (branch checkout, staging, stashing, etc.) - Or run ggc for familiar subcommands - Built-in workflows like addcommitpush and stashpullpop - No external dependencies — just Go stdlib + x/term It’s open source, and I’d love to hear what you think — especially if you’ve built CLI tools or worked on similar ideas.

Are self maintained language frameworks worth it?
https://www.reddit.com/r/programming/comments/1m17sde/are_self_maintained_language_frameworks_worth_it/
<!-- SC_OFF -->I recently joined a company that uses Haskell for its backend. On top of that, they’ve built their own custom framework for it. Since I’m new to both Haskell and this in-house setup, I’ve been wondering: Was it really necessary to build a whole new framework? What kind of circumstances make maintaining your own framework worthwhile? Are the trade-offs—like developer ramp-up time and maintainability—justified in the long run? Curious to hear your experiences or opinions—especially if you’ve worked with in-house frameworks in lesser-used languages. <!-- SC_ON --> submitted by /u/Willing-Bookkeeper75 (https://www.reddit.com/user/Willing-Bookkeeper75)
