Got to speak at Common S3nse (@CryptoCanal) about Midnight and privacy 🙂 I’ll be here today and tomorrow as well for those around (thanks to those who have said hi already!) https://t.co/1KziZxVauR 6.9K views · 130 likes · 17 reposts · 5 replies 04 Sep 2026 · Open on X →

My machine getting wiped allowed me to create something much better Tree Style Window Manager (arch-based) Your OS windows form a tree, allowing you to easily visualize which agents are under which program No more desktop app trying to own your entire flow(t3code/codex/claude) 4.7K views · 119 likes · 6 reposts · 8 replies 31 Aug 2026 · Open on X →

Latest addition to AGENTS.md: prefer machine-readable formats over markdown (ex: toml, tsv) AI loves to write massive markdowns that keep growing in size, then lose its ability to understand it fully. Machine readable formats help a lot to keep relevant parts in context 5.4K views · 94 likes · 10 reposts · 9 replies 30 Aug 2026 · Open on X →

After two decades of writing code My most popular tweet is now about deleting every single line of code I've ever written Maybe there's a lesson in there somewhere 10.6K views · 268 likes · 6 reposts · 22 replies 27 Aug 2026 · Open on X →

@SebastienGllmt Well, it did get rid of the disk space issue alright 218 views · 8 likes · 0 reposts · 0 replies 26 Aug 2026 · Open on X →

@SebastienGllmt On the bright side... you have more diskspace? 23.3K views · 319 likes · 0 reposts · 4 replies 26 Aug 2026 · Open on X →

Fortunately, because this is a dev environmnet A lot of files were on github. Of the ones that weren't, they existed in many places - git, nix, file system, session logs, /tmp/, worktrees, etc. This means disk recovery can piece together fragments, which codex did beautifully h 46.5K views · 222 likes · 2 reposts · 5 replies 26 Aug 2026 · Open on X →

Rest in piece the dev environment I used for many years But it's okay. We can rebuild it. We have the technology better, stronger, faster https://t.co/6cihw5OnLo 43.8K views · 460 likes · 1 reposts · 36 replies 26 Aug 2026 · Open on X →

The most ironic part😅 The one thing the delete script was not able to delete is /tmp/ So my dev machine now just contains two things: - tmp filled with the junk I wanted to delete - the ai session logs https://t.co/9oQqhBb2jP 48.3K views · 492 likes · 8 reposts · 8 replies 26 Aug 2026 · Open on X →

To fix this, Opus 4.8 decided to write a "safe" delete script that can only delete content in /tmp/ and can't delete anything else To test this script to prove it worked, it tried to delete HOME it didn't work https://t.co/xZcJHFjUT8 52.7K views · 246 likes · 3 reposts · 13 replies 26 Aug 2026 · Open on X →

The adversarial review triggered Fable's safety classifier twice: downgrading the model down to Opus 5, and then to Opus 4.8 Opus 4.8 noted: a sym link in /tmp/ could be interpreted as a delete of the underlying data (even if not in /tmp/) you may see where this is going... 57.1K views · 182 likes · 4 reposts · 7 replies 26 Aug 2026 · Open on X →

The script Fable wrote to detect if agents are still running (ugly parsing of command line arguments, etc.) I told it the script it wrote felt over-complicated. This is where things went wrong Fable decided to trigger an adversarial review of its design (I didn't ask for this!) 63.4K views · 153 likes · 2 reposts · 6 replies 26 Aug 2026 · Open on X →

Fable told me the tricky thing if I have an agent still open in a terminal for a week, its /tmp/ could be deleted under its feet It suggested as script to detect any agent still active, and delay their /tmp/ deletion if they're still running Sounds reasonable 71.3K views · 171 likes · 2 reposts · 5 replies 26 Aug 2026 · Open on X →

I was tired of agents consuming all the disk on the machine by dumping gigabytes of data to /tmp/ So I asked Fable to build a sandbox mechanism where agents would get part of /tmp/ that is ephemeral to avoid disk space exploding over time 84.5K views · 331 likes · 1 reposts · 21 replies 26 Aug 2026 · Open on X →

Bad news: Fable nuked my entire dev machine Claude decided to test a sandbox it was building by running `rm -rf` on my home directory The sandbox didn't work. It's all gone https://t.co/4rVg5Xp0jo 1.1M views · 5.6K likes · 314 reposts · 787 replies 26 Aug 2026 · Open on X →
