Hi, I'm Felix. I'm an eng lead working on Claude. I love watching people take flight and do things they never thought possible.
We often describe that as "being more ambitious" when using AI, which is tricky advice to follow. I wrote a tutorial:

Today we're standing up XBOX LABS (labs.xbox.com). Here is the note that I sent to the team:
Team,
The first video games emerged some 75 years ago. In the time since, there have been booms and busts, but every year there are more great games to play, more devices to play them, and best of all, more people than ever playing. That growth helped make XBOX what it is today, and we've helped shape the industry in return, from bringing hard drives to consoles and online gaming through Xbox Live to Game Pass and cloud gaming, alongside franchises that have brought millions of people together.
In recent weeks, we've seen games rapidly decompiled and rebuilt to run on hardware they were never originally designed to support. Windows PC builds have been translated to run on Apple Silicon or ported to run inside a browser through WebAssembly and WebGPU, the latter now approaching 90% global browser support. Perhaps more surprisingly, we've seen many of the biggest games in the world have been remixed into the source code of another.
These experiments challenge long-held assumptions about our industry: the tether between software and hardware, the boundary between creation and play, and how people discover and experience games. While it is hard to predict the future of gaming, it is easy to see the possibilities in making great games easier to access, giving old games new life and allowing more players to become creators and co-creators. These are unmistakably good outcomes for players, even when (and sometimes because) they challenge our existing business models.
To explore these possibilities, I’ve asked Scott to stand-up XBOX LABS, a small group of game makers, engineers and scientists whose job is to turn emerging ideas into things our players and developers can experience. We'll build in the open, learn from what people do, and measure success by whether more people are playing and creating.
I think XBOX has an important role to play here. Coding became the first major workload for agents because they can write, run, and test software. Games share many of those same properties, and people spend more than 72 billion hours a year playing XBOX games, roughly five times the estimated time spent writing code worldwide. We've spent 25 years learning how to make great games, and I want our game makers to help shape what these new technologies make possible. As we learn, we’ll share the tools we build with developers across the industry, just as we always have.
Our priorities aren't changing. We remain committed to the 4Cs, to making great games, to our hardware and to being responsible stewards of IP and the communities built around it. LABS gives us a way to explore new technology that is game design led without abandoning the work already underway.

Crazy stuff, cool read!
New on our Engineering blog: Creating in-house source control.
In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale.
Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…

Ben Affleck reveals he writes Python, understands convolutional neural networks, worked extensively with GPUs, and used his celebrity status to get private looks at Google and OpenAI’s video models
“I’ve always been kind of into computers since I was young. Then, when film started to move from analog film to digital, I became more interested in that aspect of it. The visual-effects workflow for many years has included machine learning, so I can write pretty shitty Python scripts and stuff like that.
“With convolutional neural networks, which were the precursors to what the transformer can do, which is much more computation simultaneously, you would do things like look at what’s called a tensor. That’s the numerical translation of a visual image in numbers, like the batch number, the frame number and the red, green and blue values of each pixel in each frame. It’s just that simple. That numeric is called a tensor.
“You’d use a convolutional neural network to identify patterns that reveal what’s called edge detection or feature extraction, which is identifying patterns well enough to know, this is where the window ledge is, so we can more easily take the green-screen image out and replace it with something.
“That was familiar to me early on because, prior to Artists Equity, I had a small visual-effects company. I’ve worked with GPUs a lot too. The visual-effects guys said, ‘Hey, you should see. There are a couple: Google and this other company, OpenAI, are doing really interesting stuff with transformers in video.’
“I’ve learned that I can actually just call up and go, ‘Hey, it’s Ben Affleck. Can I come see what you’re doing?’ Sometimes people say yes, to my astonishment.”
$ANET Andy Bechtolsheim says AI has made optics demand about 10 times bigger in five years and the industry is only at the "very beginning"
"So I guess I don't need to tell you that AI has been driving this incredible increase in demand for high-speed optics, which is probably now 10 times bigger than it used to be five years ago..."
"And what I want to talk to you today is that we're not at the end of this journey, but rather the very beginning. There's easily another order of magnitude increase in bits needed for the next generation kind of data centers."
"So what I want to talk about first is what's happening at the data center level, and how we as an industry have to get together to solve these problems of this very rapid and high demand growth as fast as possible, since AI can't wait."

This is the way. Accept code on merit and ensure that a person takes accountability for it. Doesn’t matter if it was typed, chiseled, generated, or bit-flipped via magnetized needle on a chip.
If it’s good, it’s good. If it’s slop, it’s slop.
KDE is working on an official AI / LLM policy, and it reads like the rules of Fight Club.
In short, KDE’s AI policy:
1) Encourages using AI, as long as a human is kept “in the loop”.
2) But you can’t tell anyone that you used AI.
“Don’t disclose LLM usage”.
“Don’t add ‘Assisted-by: [some LLM]” (as is done in the Linux kernel).
“Nobody in KDE should know if you use an LLM”.
In other words: “Welcome to developing KDE with AI. The first rule of developing KDE with AI is: you do not talk about developing KDE with AI.”

As one of the co-founders of open source, I fully endorse this message.
I didn't write down the theory of open source and then persuade the mainstream to embrace it just so it could become a political chew-toy for the people this guy rightly calls "screeching retards".
I have never seen a take trigger so many retards into hallucinating and blasting out the worst possible criticisms.
Yeah, he's rich and maybe he's a little hypocritical to make political points while saying he's being apolitical, but like.
Who the fuck cares. He's bringing people into open source, and now the screeching retards once again make the normies go "wow I want nothing to do with this".
SHUT THE FUCK UP AND EMBRACE CHOICES AND GROWTH IN THE OPEN SOURCE ECOSYSTEM.
Remember all of the times some rich and powerful entity did some things and it made FOSS better in the end because we can always fork projects that get hijacked?
Look at who is paying the Linux Foundation and other open source institutions, and look at the people who are actually putting in the work to build out open source to make the entire ecosystem better. They're not random brokies.
If you don't like it, shut the fuck up. Fork. Write your own code. Maintain your own shit with 500 million users for free. I don't care. If you're not going to do this, shut the fuck up and get the fuck out of MY industry. Fuck you.

In March 2026, I started on a TUI-based music player called cliamp. It was made as a tribute to Winamp, which we all love.
I gained traction on my first post, which was really shitty compared to what I can do now, but nostalgia kicked in.
It was a few months ago, included as the default Omarchy TUI music player.
cliamp has separate providers, like
- Spotify
- YouTube Music
- Jellyfin
- SSH streaming
- Local streaming
- 30k+ radio channels
- And much more
It can run in daemon mode (no tui), it has IPC to be controlled by and from whatever you want, a full cli.
The cliamp radio channel has exploded, and in the last seven days it has had around 115,000 sessions in total.
The goal is to make cliamp even better, so I am working on the architecture. E.g., better IPC, so you can run it in daemon mode and build what you want on top of it to control it.
I am also working on a GUI version that will use the IPC, as many have requested a GUI.
Anyways, here's a short video of cliamp. It is pretty. It might not be the best UX to use yet, but it is the prettiest TUI music player out there.
Thanks
This might be the best video Syntax has put out all year.
