Hello friends!
Welcome to this week’s Sloth Bytes. I hope you had a great week.
You think 4x faster than you type. Your IDE should keep up.
Wispr Flow lets you dictate prompts, acceptance criteria, and bug reproductions inside Cursor or Warp — with automatic file name and variable recognition. Say user_id, get user_id. Say useEffect, get useEffect.
Paste directly into GitHub, Jira, or Linear. Give coding agents the full context they need without typing a novel.
89% of messages sent with zero edits. Millions of developers use Flow daily, including teams at OpenAI, Vercel, and Clay. Free on Mac, Windows, and iPhone.
Ghost: Unlimited Postgres For Agents
Your agent builds faster than a 2-project free tier allows. Ghost gives it unlimited postgres. No credit card. Try free.
Claude Code just got a lot less stingy, thanks to SpaceX
Unexpected blessing this week if you felt like running one prompt in Claude Code was nerfing all of your tokens.
Anthropic just announced a partnership with SpaceX that substantially increases compute capacity, and the rate limit changes landed immediately for Claude Code users:
Claude Code's 5-hour rate limits are doubled for Pro, Max, and Team plans
The peak hours limit reduction is gone for Pro and Max: no more getting throttled during busy hours
API rate limits for Opus models are substantially raised
The SpaceX deal is part of a broader push Anthropic has been making on compute infrastructure. More compute means more headroom to actually let people use the thing instead of hitting walls every few hours.
CVE-2026-31431: A 732-byte script that roots every Linux distro since 2017
copy.fail dropped last week and it's not great news if you run Linux servers.
The short version: one Python script, 732 bytes, gets you root on basically every Linux distro shipped since 2017. Ubuntu, RHEL, Amazon Linux, SUSE: same script, no modifications needed. A researcher named Xint found a logic bug buried deep in the Linux crypto layer that, when chained together with two other kernel interfaces, lets you write 4 bytes anywhere in memory you want. That's all it takes.
What makes it worse than your average Linux exploit is that it doesn't need any of the usual tricks. No race condition, no guessing kernel offsets per distro. It just works, every time, reliably.
Two more things that make it harder to defend against than normal: your file integrity checker won't catch it because the exploit writes to memory, not disk. And if you're thinking "at least I'm in a container". It escapes those too.
A patch is available. If you run Linux servers or containerized workloads, update now.
The creator of Vagrant and Ghostty just rage-quit GitHub. Kind of.
Basically, an update on last week’s news.
Mitchell Hashimoto has been GitHub user #1299 since 2008. He built Vagrant, co-founded HashiCorp, and more recently made Ghostty, the terminal a lot of you are probably using right now. The guy lives and breathes open source.
This week he wrote a post saying Ghostty is leaving GitHub. Not because of drama, not because of politics. Because it keeps going down. He literally kept a journal for a month marking every day GitHub broke his workflow. Almost every single day had a mark. On the day he wrote the post, GitHub Actions had been down for two hours straight.
So he's moving everything: issues, PRs, releases to a self-hosted Gitea instance. Done.
The post blew up on Hacker News immediately, and honestly the comments are full of developers who've been quietly feeling the same way. When someone that embedded in the platform for 18 years finally says "I'm out," it hits different.
GitHub is so dominant most of us never think twice about alternatives. Maybe worth having a backup plan.
Why TUIs are back in 2026 - a good explainer on why terminal UIs are having a genuine renaissance. Electron fatigue, AI agents living in the terminal, and macOS/Windows losing native UI coherence all contributed. If you've been curious why tools like Warp, Charm, and Ghostty are getting so much traction, this explains it.
Container filesystem from scratch - an interactive tutorial that builds a container filesystem layer by layer from nothing. Covers overlay filesystems, image layers, and how Docker actually stores and stacks changes. The kind of thing that makes containers feel a lot less magical and a lot more understandable.
Stripe formatted 25 million lines of Ruby overnight - Stripe runs the world's largest Ruby codebase and used rubyfmt, a zero-config Rust-based formatter, to reformat all 25M lines in a single night without breaking anything. The interesting part is how they did the rollout: staged by team, automated conflict resolution, and a custom diff strategy to prevent git blame becoming useless.
Bash is not enough for large-scale CI - a well-argued case for why shell scripts can't replace a proper CI orchestrator once you hit scale. No error propagation, no dependency graph, no retries, no distributed execution. Written by someone who has built CI systems at scale and clearly had to have this argument many times.
Bun just shipped a native S3 client - Bun added a built-in S3 client directly into the runtime. No SDK install, no aws-sdk dependency, just Bun.s3. Supports streaming, multipart uploads, presigned URLs, and works with any S3-compatible storage (R2, MinIO, etc.). For anyone running Bun in production with cloud storage, this is a nice reduction in dependencies.
GitHub alternatives: GitLab, Codeberg, Sourcehut - not saying GitHub is going anywhere, but the recent breach is a good reminder that single points of failure are risky. GitLab is the full-featured alternative with self-hosting. Codeberg is the privacy-first open source option. Sourcehut is for the "I want everything to be minimal and fast" crowd. Worth knowing your options.
Zero to Mastery ML course materials - Daniel Bourke's complete ML and data science course, fully open on GitHub. Covers everything from NumPy basics to neural networks and deployment. One of the best structured learning resources for getting into machine learning without paying for a bootcamp.
That’s all from me!
Have a great week, be safe, make good choices, and have fun coding.
If I made a mistake or you have any questions, feel free to comment below or reply to the email!
See you all next week.
