I'm joining @OpenAI at the end of the month, and I can't wait to get started! I'll be working on everything related to Codex, bringing what I learned building Codex Monitor, and working with the developer experience team!

What's the point anymore? Codex literally reviewed 500+ open issues, grouped them, and sorted them for me in less than 3 minutes. Everything became easy. It's just a matter of will, drive, and ideas. The only bottleneck is me having to manage all that

But this will be solved soon. If I had enough time, I would code an autonomous Codex GitHub agent that basically takes issues one by one, implements them, tests them, or closes them.

The future is literally at our fingertips. I believe we're almost there with the model if we build enough tooling to become autonomous around it. And if we're patient enough, we'll get the model that will do all of it itself anyway.

I keep seeing people say they'll get rusty if they let the AI write everything. Well, the truth is that you can't compete anyway. It's time to sharpen your agentic skills rather than refine your decades-old programming skills.

One thing that didn't change with agentic programming is that good software is still obsessing over every little detail. Both technical and UI based. That's still the fun part for me.

I've been testing the Codex official macOS app for the last couple of weeks. Yes, funny, I know! But I didn't know they were making their own until a week after I started and released Codex Monitor! It's OpenAI's take on the IDE of the future, and it's pretty good! 🧵for more

All in all, it's a very solid first release! I can't recommend it enough; this is truly the flow of the future, and I'll only improve from there. It has many different features from Codex Monitor. I see my own app as a simpler/leaner version of the Codex official app.

And I'll continue to maintain mine; both can cohabit. I don't see a problem with it. And the Codex team has been amazing with all the feedback they've gotten on their own app, and it's already steadily improving!

About worktree: the Codex app has a very cool feature. Once you have changes on a worktree, you can sync the change to your local repo, it'll create a branch for you and keep it in sync between your worktree and repo. This is amazing and makes Worktree much better to work with!

And it also has all the features you expect from this kind of new, agentic-driven environment. A sidebar with the git diff changes, a terminal, a way to quickly add and sort workspaces, easy access to all Codex /commands, plan and code mode, etc... And multiple run commands!

Another awesome feature is that you can easily start new agents locally, in a worktree, or as a cloud agent. To me, that's a super powerful feature! Your worktree and cloud agents are combined in the sidebar. And you can easily apply cloud/worktree changes on your local repo.

Another feature they have is automation! You can create an agent cron job that runs on a specific day at a specific time. In my case, I have a daily review of my open PR and issues, but what you can do is pretty limitless!

You can see all your agents' threads per workspace in the sidebar and quickly switch between them. It has most of what I ever wanted from those new kinds of agentic/orchestrator IDEs. And no, no code editor, we all agree on that!

You can also manage and edit your skills and install new ones from an ever-growing marketplace of skills! Also within the new Codex app! Can't wait to see where this will go. Skills have been a bit messy, with a ton of libraries and repos all over the place.

I’m on X and I see the retarded White House posts, the fat JD meme and the massive no kings protest. And I’m here and I see the same things. I think it’s how it should be.

TBH I don’t think blocking is a good idea. You need to see the stuff, you need to know about it. Blocking something online doesn’t make the problem disappear. It just makes him think you live in a fairy tale. And it’s not real.

This post is unavailable.

New UFO documentary to make you believe there is a cabal of elites with enough organizational power to hide all that stuff from the public. And it’s international and all that shit. Brother, we can’t even have one stable government, and you want me to believe that?

If you like living in an autocracy, this is what it looks like. You can, as an American, make fun of Russia all you want, but soon your country will be the same. No press, no governmental agencies for statistics, no accountability.

When you are an iOS developer, every day is Xmas - LLM edition: I didn’t grasp this at first. This is using a third-party LLM, running with Apple’s MLX and using their new system that maps LLM output into Swift structured data. This is how he got that nice UI updating live.
