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.

Predicted this 🙃

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?

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

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

A highly requested feature has just shipped in T3 Chat 👀

Devs working on their side projects

"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.

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

We need more that look like this

"Why do you use gpt-5.6 and kimi k3 inside of Claude Code?" This vid goes in depth on what Claude Code gets right, what Codex gets wrong, and how to copy my setup :) Blessed by Tibo btw

Kimi K3 is really, really good.

This is the most pissed off I've ever been on camera.

I have officially moved the majority of my dev work over to Linux. I couldn't be happier. Here's a video about how and why I made the move.

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

I'm sorry, I need to crash out about local models for a bit.

Over the last month, I burned over $200k in tokens with gpt-5.6-sol. I built a lot. Instead of just reacting to the benchmarks, news, tweets, etc, I went a different route. This video is an overview of all the cool shit I built using the new model. Proper review coming soon™

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

"Ultra" mode is not what you think. I did a deep dive on Codex's newest feature to try and help y'all understand it better.

The Codex app is dead, and I am unhappy about it.

Happy America Day nerds

"This article could have been a video" (did a deep dive on how to maximize usage in gpt-5.6 on your Codex subscriptions)

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

Oliver Tree will be mostly remembered for memes. I hope we don't forget that he was a genuinely great artist too. Feels like a good time to share his debut track "Forget It" (w/ Getter). RIP Oliver. You brought joy to millions in your short time here. 💙

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

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

I have a lot of ideas. I wish I could build them all. I don't have the time. I decided to give them all away in hopes of someone else building them.

If you're curious how I managed to do over $20,000 in inference on the last 48 hours, here's a video all about it. Spoiler: loops are really powerful

Here's the video that Charlie Greenman is still trying to get taken down over a year later. Posting here because X is unlikely to fall for false reports of "privacy concerns" due to public tweets being visible in a video.

Don't make the same mistakes I did. Here's a video on how to get the most out of Fable, full of real world examples of Fable helping me ship.
