Predicted this 🙃

Introducing SoraMarker - the easiest way to add the Sora watermark to any video

Grok 3 is, uh, not great at coding

Claude Code has regressed an absurd amount in the last few days. Timestamps no longer update unless you un-focus/re-focus the tab. "thinking" doesn't show at all. I had a query run for 6 minutes with 0 output. This is genuinely unpleasant to use.

I made a Chrome extension that blocks Twitter unless I have work currently running in Claude Code

Took a bit of hunting, but I managed to get a VLC v4 nightly build running on my Mac. It's so good. Buttery smooth. Zero issues. UI is significantly better too. How can we help ship this faster, VideoLAN?

Skate spot is swarmed by Super Bowl stuff and an anti circumcision protest lol. Will still be here an hour or two at least

Backend devs supporting frontend devs

Eight Sleep Tried reinstalling app and everything with no luck. I just want to sleep 😭😭

What a wild ride this has been. Over 7 million messages backfilling on demand, with another 15 million on the way. We did it. Everyone's now using the latest T3 Chat. I'm so relieved we finally shipped.

Grok 3 is here and it fails the "hexagon ball bouncing" test spectacularly

T3 Chat now runs R1 over 6.5x faster than the official DeepSeek API

Dev: "it's a simple feature, the user will understand" User:

Miss this. Can’t wait till I’ve healed up and can skate more

"I bet you, if you dig hard enough, you could find a way where GW Basic is faster than Rust" Your understanding of programming languages is too far removed from reality to take part in this discussion.

A highly requested feature has just shipped in T3 Chat 👀

mark I thought making a browser was supposed to be hard?

Devs working on their side projects

We need more that look like this

T3 Chat now supports image upload! Only with Claude for now (blame Azure)

I'm scared to make this video, but I feel like I have to. It's time to talk about Google.

swe-bench is kind of a shitshow, and it makes evaluating LLMs hard. DeepSWE is the first agentic code bench that makes sense.

Struggling to pick what agent, model, and effort levels to use? Miss the "slot machine" feel of Claude Code when using other tools? `npx slotslop "[prompt]"`

Sensitive content

Claude Mythos is the start of the end. I think this is my psychosis moment.

Codex, Claude Code, and Cursor are all great tools. They're also much more different than you think. I did a comparison of the three, but not in the usual way. I went deep on how they differ philosophically.

The GitHub hack is really, really bad.

Claude Code is basically unusable at this point. I give up.

You should delete your CLAUDE․md/AGENTS․md file. I have a study to prove it.

Opus 4.8 is here. It's pretty good. Is Anthropic back on top?

I cancelled my Claude Code sub. I give up.

Coding with agents is a trap, and we all fell for it.

Wow, someone already made a whole movie in the Ghibli style

Agent harnesses aren't the black magic many of y'all seem to think they are. To prove it, I built one.

Agents are good at bash. Bash is not good for agents. We should cut our losses and restart now before it is too late.

My AI coding workflows have changed a lot over the last few months. 5.5 forced me to rethink everything, and I'm better for it.

The Claude Code Desktop app is an affront on software. As developers, we should be offended that they chose to ship something this awful. Rushed out my video because I feel like I'm going insane.

Apple is falling apart. I can't take it anymore. Here's a video of me crashing out about it for an hour.

The Niri window manager feels like exactly what I was looking for. Holy shit this is good.

Moltbook is one of those rare moments in time where you can tell everything is changing. I filmed myself exploring and...yeah...

Third episode of Nerd Snipe is live! This time I try to get Ben in on my Anthropic conspiracy theories (and explain why Claude got dumber) 00:07:30 T3 Code Banned? 00:16:08 How Claude Caching Works 00:24:00 Why Claude Seems Dumber 00:38:03 The Conspiracies Begin...
