Mark Di Marco

`lt` has been a fun toy project. I doubt the population of TUI enthusiasts and Linear.app users is very big, but the point of the project was to build something for me, and learn some #rust along the way.

Thanks for the post! It was fun to see a few GH stars trickle in. Thanks for your work on @ratatui.rs, it is a fun library to work with.

Is this vibe coding? Asking for a friend.

Thanks! In mobile the menu is rough. Sort of slapped the mobile fix on at the end, not super proud of that. I’ll take another look and see if I can make that better.

I put together a website that lets you compare programming language features across multiple languages: dialectical.dev

I’ve got Zig, Rust, Nim, Python, Kotlin, Typescript, Elixir, Go, and Gleam in there.

LMK if I should add anything else! Language concept or language.

ep9 v8: Initial implementation of optional chaining ⛓️‍💥 A quick tour through compiler design to see how v8 implemented optional chaining in Javascript

It was fun to see how v8 (and this @nodejs.org and @chromium.social and co) added optional chaining (?.) to the language. Just ~250 lines of code to get the initial version in!

Node.js — Node v23.6.0 (Current) Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine.

Node.js v23.6.0 is out! 🥳🎉

This release enables the flag --experimental-strip-types by default.

Node.js will be able to execute TypeScript files without additional configuration!

⚠️ This feature is experimental, has limitations and is subject to change.

The Day 1 #AdventOfCode solution we've all been waiting for: COBOL

65 years ago a committee met in the Pentagon to standardize a new programming language, and soon COBOL-60 was born.

Can you guess the name of the sorting algorithm used in the SORT-ARRAYS procedure?

I look for commits in all sorts of programming languages, and so far throughout my research, Zig has been my favorite “new” language that not enough people are talking about.

Here were a few patterns from my Bun.sh episode that stuck out:

@ziglang.bsky.social

waffle tips + waffle stroke + waffle unit: auto by Fil · Pull Request #2215 · observablehq/plot unit: auto (closes waffle unit: auto #2214) waffle tips #2132 (merge commit, closes Waffle mark tooltips are always on axis line #2129) waffle stroke #2204 (merge commit closes Waffle pattern doe...

@fil.rezo.net and I are working on further improvements to the waffle mark, including better tooltips, better stroke, and a better default unit for very large or very small values. github.com/observablehq...

ep8 plot: waffle mark 🧇 Observable's data visualization library is full of fun little tricks, especially with this waffle mark commit

The implementation of the waffle mark in @observablehq.com’s Plot library is a lot more elegant and clever than I thought it would be: open.substack.com/pub/commithi...

ep5 zed: Improve performance of select-all-matches Speeding up Zed's select-all-matches by a factor of 250 with 75 lines of Rust

A review of a fun small commit to the @zed.dev editor that had a huge performance boost - always fun digging into commits like these. open.substack.com/pub/commithi...

ep7 duckdb: Add Damerau-Levenshtein string comparison function A flashy new open-source database and it's relationship to academic papers from the 60s and 70s

I had a lot of fun exploring the origins of some @duckdb.org functionality in my latest Commit History episode! open.substack.com/pub/commithi...

I’m looking for interesting open source projects to do an episode of my show on!
