Free Open-Source Time Tracker ActivityWatch is an app that automatically tracks how you spend time on your devices. It is the best free and open-source time tracking software for Windows, macOS, Linux, and Android. It is privacy-first and cross-platform, and a great alternative to services like RescueTime, ManicTime, and WakaTime. Unlike closed-source time trackers, your data stays on your device
For the last several years, I’ve been building and maintaining developer tools in my spare time, chiefly mise. What started as a simple rewrite of asdf in Rust has become an incredibly successful local dev manager. mise now has 27k+ stars on GitHub and is the 10th most downloaded Homebrew formula. In fact, roughly 1% of users typing brew install are running brew install mise. I’ve also watched mis
I've sold out 2026-04-08 What a nice WebGL shader. Look at draining your battery. Table of contents So, this is awkward. I've joined Cristina, Jakob, Ramiz, Vegard, Armin, and Colin at Earendil. And I'm taking pi, the little coding agent that could, with me. Now, before you get out the pitchforks, hear me out. Why would you do that? Many reasons! Let me give you a "quick" history lesson. "It's lik
Introducing EmDash — the spiritual successor to WordPress that solves plugin security2026-04-01 The cost of building software has drastically decreased. We recently rebuilt Next.js in one week using AI coding agents. But for the past two months our agents have been working on an even more ambitious project: rebuilding the WordPress open source project from the ground up. WordPress powers over 40%
Because code gets cheaper and cheaper to write, this includes re-implementations. I mentioned recently that I had an AI port one of my libraries to another language and it ended up choosing a different design for that implementation. In many ways, the functionality was the same, but the path it took to get there was different. The way that port worked was by going via the test suite. Something rel
The latest news from Google on open source releases, major projects, events, and outreach programs for early career developers. by Cyrus Stoller & Miguel Osorio, OpenTitan Last year, we shared the exciting news that fabrication of production OpenTitan silicon had begun. Today, we're proud to announce that OpenTitan® is now shipping in commercially available Chromebooks. The first OpenTitan part is
The React Foundation has officially launched, hosted by the Linux Foundation. In October, we announced our intent to form the React Foundation. Today, we’re excited to share that the React Foundation has officially launched. React, React Native, and supporting projects like JSX are no longer owned by Meta — they are now owned by the React Foundation, an independent foundation hosted by the Linux F
More than a million developers use OpenAI’s multi-agent coding assistant every week. Named Codex, usage has increased 5x since the start of January, the team tells me. In the first week of February, OpenAI launched the Codex desktop app, a macOS application that CEO Sam Altman calls “the most loved internal product we’ve ever had”. A few days later, OpenAI shipped GPT-5.3-Codex, which they describ
Find places by name or address (Geocoding) Nominatim can power the search box on your website, allowing your users to type free-form queries (“Cafe Paris, New York”) in any language. It also offers a structured query mode (“postcode=12345”, “city=London”, “type=cafe”) that helps you to automate geocoding of extensive address lists. Look up addresses for a location (Reverse geocoding) Given a latit
2025年のオープンソース活動の振り返りとGitHub Sponsorsでの収入をまとめた記事です。 今年はtextlintとJSer.infoにMCPサーバーを実装しました。 また、JavaScript PrimerをES2025に対応し、secretlintに新しい検出ルールを追加しました。 AI連携とECMAScript最新仕様への対応が中心の年でした。 TSKaigi 2025とYAPC::Fukuoka 2025では、継続的なメンテナンスについて発表しました。 サプライチェーン攻撃対策についてはZennに記事をまとめました。 npmパッケージ/GitHub Actionsを利用する側/公開する側でサプライチェーン攻撃を防ぐためにやることメモ 今までの振り返り 2014年: https://efcl.info/2014/12/31/oss-in-2014/ 2015年: https
by Tanner Linsley on Nov 24, 2025. Two years ago I went all in on TanStack. No consulting, no safety nets, just a commitment to build open source at a professional, sustainable level. What started as a handful of libraries I built at Nozzle has grown into a real ecosystem powering millions of developers and many of the largest companies in the world. I can share plenty of numbers in this post, but

The Challenge Free, publicly available source code is the infrastructure on which all of digital society relies. It is vital to the functioning of governments, private companies, and individual lives. However, few realize that public code is built and maintained almost exclusively by unpaid volunteers, and the enormous amount of work required is in desperate need of institutional support. Without
React Conf is around the corner and it's been almost 10 years since Prettier was released. I figured it would be a good time to recount the journey from its early days to now. This is the story of how the "Space vs Tabs Holy War" ended, not through one side winning over the other but instead a technological invention making it the underlying source of tensions no longer being a thing. Back Story S
米国においてオープンソース・ライセンスが契約ではなく「著作権の一方的な許諾」であると長らく見做され、Jacobsen v. Katzerの訴訟でその効力が法的にも認められるようになった流れは前回の記事で解説したが、一方でこの訴訟の判決はオープンソース・ライセンスが法的に強制力のある契約として認知されるまでの道のりの一歩でもあった。 今回は4つの訴訟での判示からこの長い道のりの過程を詳細に示しつつ、ライセンスが強制力のある契約として確立することで、国境を越えたライセンス違反リスクにどのような影響が生じているのかを日本企業、そしてコミュニティへの影響を含めて解説していく。 English version: https://shujisado.org/2025/09/17/from-permission-to-contract-dual-enforcement-and-rising-risk-i
