#TIL go:embed has a "all:" rule. Without it, dot files are silently ignored. Took me* a while to figure out! * my coding agent

Life cycle of a single purpose tool: - first draft as a shell script - 2nd version as a python script when it's a couple hundreds of lines - 3rd version as a Go package when it grows to thousands of lines Back in the days this used to be annoying, now coding agents make the evolution seamless.

Dear googler friends following me, ChromeOS 144 broke flip laptops like HP dragonfly / brya. Flipping is not detected anymore. please fix asap

ksid: fast 63 bits sortable unique IDs in Go - Generation: ksid (~33 ns) is >7.5x faster than both uuid v4 (~250 ns) and uuid v7 (~290 ns). - Encoding: ksid (~24 ns) is ~2.7x faster than uuid (~65 ns). - Decoding: ksid (~8 ns) is ~1.8x faster than uuid (~15 ns). Use case: <1000 ID/µs, <100 servers

[The Onion article proposal] A nation that idolizes psychopaths surprised popular psychopaths act in psychopathic ways.

Happy LLM quota cool down period for those who celebrate

#TFW you have clean go.mod, add *one* "tool" line and it creates a 779 lines go.sum file.

If you ever wrote Go with the official OpenAI or Anthropic SDKs, you know how this feels... (it looks even more fun with bluesky compression) genai is a sane AI library, made for both humans and coding agents. v0.2.0 just came out! pkg.go.dev/github.com/m...

People with engineering productivity background have an unfair advantage with coding agents.

#TFW opus is editing a python file, a new pylint warning triggers, and opus disable the warning in .pylintrc. good dog.

"Ok anything I should note before I clear your memory?" is a surprisingly effective prompt just before clearing a long planning session, especially if you just asked to dump everything in a markdown file just before.

Love Go? Love AI? Hate their SDKs? Try genai! An opinionated high performance professional-grade AI SDK. I just released v0.1.0. I love to hear feedback. maruel.ca/post/genai-v...

Two decades ago, Peter and I were reviewing every single change on the internal Chrome mailing list. I got really good at doing a lot of code reviews fast. We were very pedantic. It helped the chrome code base to be coherent. I didn't know this skill would be so valuable today with coding agents!

Claude was a bit too happy with killing processes, especially the desktop environment (!), therefore I made Xfce harder to kill within md. Available in the next release or use md start --tag edge

I don't understand products where the customer can pay to not see any ad at all. Advertisers will pay a shit ton of money to reach the top 1% and HENRYs, and the company just cut themselves off from this income stream! All that remains is the lower value ads. Everyone loses.

anthropic.com/news/claude-... I wish this was not the case but history proves them right.

#TIL the Shawinigan Handshake happened in Hull.

GitHub Actions have been misbehaving for two days. Who's noticed?

Safely YOLO Claude Code your git repo via SSH&VNC over Tailscale to a docker container: export TAILSCALE_API_KEY=tskey-api... git clone github.com/maruel/md ~/md cd my-project ~/md/md start --display --tailscale Then vncviewer <host>.<tailnet>.ts.net:5901 and/or ssh user@<host>.<tailnet>.ts.net

Annoying that current SOTA models have not been updated for developer.chrome.com/blog/remote-...

Claude Web + OnShape Goal: Text emboss via projection on a sphere using a cylindrical normal. Brainstormed with Sonnet. It failed but got me on the right path. You still need to know the tools, "vibe designing" will only get you this far. Value is it unblocks on flows via in-context brainstorm.

Claude translated "Plan" into "Forfait" in French and this is hilarious. "Approuver ce forfait" sounds really funny in place of "Approve this plan".

#TFW a coding agent messes up my project's SQL migration files generated by @drizzle.team and I need to clean this up manually. Me pictured below, after a few hours reading about how it all works.

I want to congratulate PP reelection as the CPC chief. This is the best way to ensure we are not governed by the pseudo Reform Party after the next elections.

a lot of public figures seem to be trying the Lance Armstrong/Bernie Madoff technique

“your clawdie is a generous upvoter”

oh my, Google gave 250k$ USD for a bug report that allowed direct sandbox escape. crbug.com/453094710

me with a cold

I now run all my tests with no retry. Whenever one flakes, I ask my coding agent to fix it. This was mostly an issue with e2e tests.

I condensed a braindump of the tips I gave to various people at the agivc.ca Ottawa Hacker House in the past weeks. Enjoy! maruel.ca/post/agent_c...

Anyone else run "claude --model haiku -p 'Say hello, nothing else'" at 5:30am to kick the 4:25 quota window earlier in the day?

never thought I'd see Gary tan tweet a Canadian flag.

it's like doing the 2nd industrial revolution in 5 years instead of 45

I have children thus I don't use nix?

I started forcing the coding agent to have a one liner "purpose" description on each source file. During the build, the AGENTS-dot-md files are populated with the list of files and their purpose via a script. It seems to help, I feel the agent guesses less and doesn't make as many mistakes.

the only way to do it (a symlink)

even today, every byte matters consider base32 instead of hex encoding

Opus just told me YAGNI I guess it's really tired I'm pushing it too hard

I can't wait for Opus to be trained to use t.TempDir() and t.Cleanup() in its next version. Using context.Background() in unit tests is so go1.23 aka 2023.

Sending `I'd like to tighten the linter for the typescript code` to a coding agents on a large enough typescript project is really fun to watch.

@rbyers.net I hope employees get ARM64 workstations soon so the team finally ship a linux/arm64 binary. :)

Ottawa folks, did you know there's a Hacker House downtown? The team organizes a hackathon this Saturday. Register at luma.com/ja2lt6zy

Twitter is similar to walking in the metro. You end up having to ignore noisy drug addicts lying on the floor. Except that there it's nazi billionaires.

Tried the 1mo BF deal on the nazi site: it had a huge impact on reach after ~2 weeks - Reach is essentially non-followers 98% - Reach (impressions) is massively dominated by iOS - Users who like my tweets are on Android, then Web&iOS - Crowd is 25y-34y

I made my coding agent container "md" work with Android's ADB so now I can have my coding agent build and push an android app to my phone over wifi, all from within a docker container! This is both incredibly dangerous and pretty cool. github.com/maruel/md

If I had an infinite amount of free time I'd get one of these and implement bluetooth heart rate monitor support (HRM BLE). That'd be really nice. I wonder if someone is crazy enough to attempt this kind of project. www.waveshare.com/esp32-c6-tou...

Dell's Thunderbolt 5 Dock (SD25TB5) delivers 240W~300W over its USB-C connector. Frankly, it's impressive.

another debugging war story!

Fascinating thar all the display ads in downtown Ottawa are variations of "screw you USA"

If you enjoy debugging war stories, read this one about adding VR support to Half-Life 2. I won't say more to not spoil it. mastodon.gamedev.place/@TomF/115589...
