If you’re a Staff PM-type who wants to work in NYC and thinks about self-improving software or how we might make software systems “evolve” more on their own; I’ve got the gig for you! Join me to build “dark factories” at @datadoghq. DMs open

Honestly, smart. Every SaaS (at least) should have a skunkworks team that is attempting to rebuild their product from scratch with the best tech periodically. This tells you 1) Is it a real worry that someone can just vibe-code you out of their stack (and how expensive is it roughly to do), and 2) Can you take any of your products and build them better with basically a full refactor/rebuild. This isn’t easy to do well. There are a lot of ways to copy the product poorly, but it’s not crazy.
This is INSANE. Cisco’s president Jeetu Patel has given a 27-year-old engineer unlimited AI tokens to try to rewrite 98% of the company’s legacy code within 24 months, Fortune reports. Padmanabhan Krishnamurthy thinks he can do it with a two-person team. He has just four weeks to prove the approach.

This might be heresy but: 1. Code reviews are a massive productivity tax with tiny quality benefits 2. They should not be mandated 3. The author should feel free to request a review if they want it 4. If you don't trust your engineers, invest more in CI, or hire better ones

last night i slept soundly while a new service ramped up to a few billion tokens come thru infer/con and learn how you too can rest easy
If your inference latency or uptime keeps you up at night, you belong at INFER/CON 😅 SF, Nov 16, with some of my favorite people to nerd out with on inference and performance: @dzhulgakov, @charles_irl , and Alexis Lê-Quôc (@datadoghq), plus many more. Join us!

"If there is a time engineers can afford to take on technical debt, it's now. A more capable model can repay it down the line. Don't overthink it." This reframes tech debt in a way that's underappreciated and extremely pragmatic advice for those building with AI today. From a chat with @stevenkplus1 at @datadoghq, with a packed cafe on a Monday afternoon. We covered Devin, AI and math, formal verification, appreciating life, and more. Reminded me of this slide on tech debt from a talk at Datadog. nitter.cf/nerdsane/status/210780…
Love all financial derivations of technical debt. This was a real/fun presentation at Datadog.

Quick but fun trip to SF with the @datadoghq crew for @vercel Ship to see @rauchg and his team do it big 🚀

Excited to introduce Scout 1.0, the model powering Bits Investigation, Datadog’s AI SRE agent for complex troubleshooting and late-night alerts. We post-trained GLM-5.3 Flash to match frontier models at much lower cost on our internal AlertEval benchmark. 🧵

Linus Torvalds says, rules prohibiting AI usage are “UTTERLY STUPID” and “idiotic”. For the Linux kernel, Torvalds says, “we’re not going to make stupid rules that say ‘you can’t use tools for X’”.

See you in SF!
TOMORROW: We'll be at @vercel Ship in SF 👋🏻 If you build on Vercel, come say hi and see how @datadoghq monitors your Vercel functions. → With Agent Observability, follow every step your AI agents take - from prompts to tool calls - and see what each one costs to run. → With Real User Monitoring, connect frontend performance to what your users actually experience. → And with Application Performance Monitoring, trace a request from your Vercel functions all the way to the services behind them. We'd love to see what you're building! @diamondbishop

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. Asha

I built my first “AI” to (poorly) play chess using Pascal when I was 13. I wish I could tell that little nerd where things would go

Wartime vs. Peacetime leadership. It’s easy for organizations to fall into design by committee and then ship their org chart when they’re in peacetime. AI acceleration should have everyone in war time. 1 product leader/vision is the right approach to take big swings.
Meta built Muse with just 200 people. “The whole executive team, everyone knew that this was probably going to be one of the most important products that Meta would ship this year.” “But we had the restraint organizationally to make sure it was a really small focused team working on it... because we knew it was a single work of art.” “This is even now starting to plague a lot of the AI labs. They become this Frankenstein, almost Cronenberg amalgamation of a bunch of different people's points of view.” “It's sort of like PM hell, where every PM has a thing that they're trying to jam into the product.” “Muse had to be the exact opposite. There's one clear point of view.” — @alexandr_wang

It's irresponsible to let humans review code
There's been a lot of debate about AI vs human code review recently. Here's some actual data and observations from inside Meta: - Engineers now push ~3x the code they did a year ago. Human review capacity obviously didn't triple. - In an analysis involving 535k+ reviewed diffs, the production-incident rate for AI-reviewed diffs was 1/50th that of human reviewed. - The revert rate for AI reviewed diffs was 1/3rd of the human reviewed. - Median review wall time dropped by 35% compared to human-reviewed diffs. - Experts then looked at every production incident caused by AI-approved diffs. A human reviewer wouldn't have caught any of those issues anyway in a manual review. - Meta's internal coding agent lands ~3,000 diffs a week, and 59% need zero human edits. Human review as default for most code changes is already obsolete, and might even be riskier. Source in comment below.
