Reply guy

The latest scourge of Twitter is AI bots that reply to your tweets with generic, banal commentary slop, often accompanied by a question to "drive engagement" and waste as much of your time as possible.

I just found out that the category name for this genre of software is reply guy tools. Amazing.

Quoting Summer Yue

Nothing humbles you like telling your OpenClaw “confirm before acting” and watching it speedrun deleting your inbox. I couldn’t stop it from my phone. I had to RUN to my Mac mini like I was defusing a bomb.

I said “Check this inbox too and suggest what you would archive or delete, don’t action until I tell you to.” This has been working well for my toy inbox, but my real inbox was too huge and triggered compaction. During the compaction, it lost my original instruction 🤦‍♀️

My thanks to Sentry for sponsoring last week at DF. Sentry is running a hands-on workshop: “Crash Reporting, Tracing, and Logs for iOS in Sentry”. You can watch it on demand. You’ll learn how to connect the dots between slowdowns, crashes, and the user experience in your iOS app. It’ll show you how to:

  • Set up Sentry to surface high-priority mobile issues without alert fatigue.
  • Use Logs and Breadcrumbs to reconstruct what happened with a crash.
  • Find what’s behind a performance bottleneck using Tracing.
  • Monitor and reduce the size of your iOS app using Size Analysis.

🎬 Slingshot

letterboxd.com/danielpietzsch/film/slingshot-2024/

Movie poster for “Slingshot”.
This review may contain spoilers. Tap or click to view.

Good space movie. Has great atmosphere overall (apart from a few soundtrack choices maybe). Liked the themes of the movie. The acting was great for the most part. And it has a good twist (or two?)! The very end is a bit unnecessary, when they could've just ended the movie right with the countdown in the airlock.

👍 Recommended!

Taalas serves Llama 3.1 8B at 17,000 tokens/second

Taalas serves Llama 3.1 8B at 17,000 tokens/second

This new Canadian hardware startup just announced their first product - a custom hardware implementation of the Llama 3.1 8B model (from July 2024) that can run at a staggering 17,000 tokens/second.

I was going to include a video of their demo but it's so fast it would look more like a screenshot. You can try it out at chatjimmy.ai.

They describe their Silicon Llama as “aggressively quantized, combining 3-bit and 6-bit parameters.” Their next generation will use 4-bit - presumably they have quite a long lead time for baking out new models!

Recovering lost code

Reached the stage of parallel agent psychosis where I've lost a whole feature - I know I had it yesterday, but I can't seem to find the branch or worktree or cloud instance or checkout with it in.

... found it! Turns out I'd been hacking on a random prototype in /tmp and then my computer crashed and rebooted and I lost the code... but it's all still there in ~/.claude/projects/ session logs and Claude Code can extract it out and spin up the missing feature again.
