🎃 Scarier than a Friday deploy

Goodbye GitBook: our handbook moved into its own (not haunted) house

Our handbook lives at the same address, but it's no longer served by GitBook. Maxime rebuilt it as a static Astro site next to our website, so it now shares the website's styles and fonts and feels like part of MarsBased.

Nothing changes for readers or editors: the content is still Markdown on GitHub, old links redirect to the new paths, and every merge goes live within minutes. One less third-party dependency, and new features are now just a pull request away.

What scares developers the most? We asked our team

• "Visual Basic source code written in perfect Spanish, including accents."

• "Light theme." 🙈

• "I'll stick with the classics: deploys on Fridays." 🏝

Git got ghosted: how Anthropic outgrew it

Juan Salvador shared this one: Anthropic went from around 2,500 merged changes a day in May to more than 30,000 in September, so they built Scion, their own source control system, and moved their monorepo off git in five months. Beyond the infrastructure, it's a good look at how engineering changes when Claude writes most of the code: the human value shifts to design, trade-offs and steering agents away from over-engineering.

A nightmare on Env Street

Two heads-ups this month. Xavi flagged that Railway disclosed on October 21 that an attacker may have accessed customers' environment variables, and it recommends rotating every secret stored there. The same day, Node.js shipped security releases for all supported lines (22.x, 24.x and 26.x) fixing ten vulnerabilities, which Marta and Àlex flagged. If you run Node.js in production, it's a good moment to update.

Your Claude Code sessions will rise again

Daniel kept putting off restarting his Mac so he wouldn't lose his iTerm tabs, each one running a Claude Code session. So he put together a small save/restore with no extra tools:

• claude-save: saves the iTerm window (tabs, order and tab groups) and records which Claude session is running in each tab.

• claude-restore: after the restart, brings the window back as it was and runs claude --resume <id> in each tab, so every conversation picks up where it left off.

Both live in iTerm's Scripts menu: save before shutting down, restore when you start up again.
