Open {re}Source has a new look: its own mark and palette, on the same design system as the other products and tools I publish. How I did the whole rebrand in eight days 👇
Julien Déramond@JulienDeramondSep 25
I rebranded everything I publish in eight days, on spare time, with Claude and a private repo. Not a designer: Claude did the visuals, I was a human colour picker. Then DTCG tokens, 4 npm packages, ~80 PRs. Now, back to Bootstrap v6. deramond.dev/blog/rebranding…
"I was a human colour picker": colour round 18 of my rebranding. Eight palettes, each pairing gold with another colour (ultraviolet, magenta, azure, cyan, jade, steel, rose, periwinkle), render the same UI so only the colours change. I picked cyan and gold.

We launched OSS Scanner, which gives critical open source projects free, periodic vulnerability scans from our strongest models. Each finding includes a proof-of-concept, and a patch where possible. red.anthropic.com/oss-scanne…

On October 8, 2026, Anthropic opened OSS Scanner: free, periodic vulnerability scans for open source projects with a critical impact on security. Maintainers opt in with a PR. Reports are model-generated, with no human triage before they reach you. anthropic.com/research/launc…

Git was built for offline humans. Anthropic's clients are agents: 30,000+ merges a day in September 2026. So they rebuilt source control in-house: Scion replaces Git, Antique does code review. The ideas are meant for Git, GitHub and GitLab. anthropic.com/engineering/re…

Redesigning source control at Anthropic

As our merges per day grew more than tenfold, source control became our biggest development bottleneck. Here, we share how we migrated to an in-house version control system in five months.

Hacktoberfest 2026 runs all October, and for the first time, pull requests don't count: it's now 300+ in-person Fests, online challenges and stickers, run by MLH and DEV. What changed, how to take part, and what twelve years taught open source: openresource.dev/articles/ha…
Timeline of Hacktoberfest's rules. 2014: four pull requests to any public repository, a T-shirt in return. 2020: projects opt in with the hacktoberfest topic, spam disqualifies; 9,598 pull requests flagged as spam or invalid. 2023: no more T-shirt, a digital badge and a tree instead. 2025: six pull requests, a T-shirt again for the first 10,000. 2026, highlighted in gold: pull requests no longer count; 300+ Fests, online challenges and stickers, run by MLH and DEV.

Due to AI, I have disabled external pull requests on all my repos. Open source, as we have known it, was fun while it lasted. (It’s been 15 years for me) I will still maintain projects and handle issues.

GitHub trick: to sort an issue search by 👍, add sort:reactions-+1-desc On VS Code, the top one is a 2015 request to change the workbench font: 3,783 👍. Works across GitHub, with any reaction. So react with 👍 instead of commenting "+1": only reactions count.
GitHub issues of microsoft/vscode, searched with is:issue state:open sort:reactions-+1-desc. First result: #519, "Allow to change the font size and font of the workbench", opened in 2015, 602 comments, 3,783 thumbs-up. Next: mouse shortcut customization, 1,926.

Also new in the guide today: chapters open with "In short" and end with "Do this now", a checklist you can tick and copy as Markdown. Shorter URLs (old links still work), alt text on 20 images. openresource.dev/guide/promo…

Nice seeing an open source project just say “we’re recharging” instead of acting like everything runs on infinite energy. npmx is pausing maintainer activity on GitHub and closing Discord for a week. Feels rare. Maintainers are humans too 💙 npmx.dev/recharging
