In November 2025, a pull request was opened for the Tailwind website repository to add llms.txt as an endpoint for, you guessed it, providing an LLM-friendly version of the popular CSS framework’s documentation. It first sat idle for a while and the issuer started pinging Tailwind employees for…

If you’d like to spend 6 or 12 weeks programming with kind, curious people, apply to RC! When we began rewriting the RC application earlier this year, I was very much inspired by one of the best question sets I’ve come across: the Oxford All Souls Examination papers. They give a choice of one or two…

It seems every generation has produced its own cohort of overeducated twentysomethings who are stranded between promise and reality, and routinely dismissed as lazy or slow growers. Ben Stiller’s 90s romcom Reality Bites captured that enduring state of uncertainty, creative ambition and emotional…

SAN FRANCISCO, May 21 (Reuters) - AI startup Modal raised $355 million in a new round of financing, valuing the company at $4.65 billion, CEO Erik Bernhardsson ​told Reuters. AI startups have been whipped by two shifts this ‌year: the surge in AI coding and the increasing scarcity of computing…

Hi there! I want to talk a bit about AI and the related shifts in the tech industry. I know this is top-of-mind for lots of y’all, and you might be wondering if it even makes sense to learn new programming skills in this environment. Let’s start with an uncomfortable truth: AI models have become…

Though I have never officially owned the title of DevOps or SRE, the majority of my engineering hours in the first few years of my career were spent on understanding and mitigating incidents. Without exageration, being oncall made me the engineer I am. I was oncall for distributed caching at Twitter…

Listen to Guido and Yoko discuss on The Trillion Dollar AI Software Development Stack on Apple or Spotify. Generative AI is here, and the first huge market to emerge is software development. At first glance, this might seem surprising. Historically, dev tools have not been among the top software…

Restate Team Updated May 7, 2026 11 min read What is Durable Execution? Durable Execution is a programming paradigm that makes ordinary code resilient to crashes, restarts, and infrastructure failures. A durable execution engine records each step of a function as it runs, so when something fails,…

TTHEY ATE TOGETHER every chance they could. They had to. The enormous photocopiers they were responsible for maintaining were so complex, temperamental, and variable between models and upgrades that it was difficult to keep the machines functioning without frequent conversations with their peers…

The social contract of writing May 25, 2026 5 min read llm writing LLMs are making inroads into just about every industry on the planet, they’re everywhere now. AI for X, AI for Y, if there’s a thing that somebody is willing to pay for, there’s another person looking for a way to use LLMs to do it.…

Amazon says it recently achieved a major breakthrough in networking design—and has been quietly deploying the new technology in its data centers since late last year. The company claims it has significantly increased data speeds while reducing energy use, potentially giving the tech giant an edge as…

Lately, I’ve been feeling like I’m losing control over the code I write when I work with agentic code generation. When I finish an agentic session, I get all the outward signs of having written code, but none of the internal processes that happen when we write code by hand. As a quick primer, the…

10th October 2025 - Link Blog Superpowers: How I'm using coding agents in October 2025. A follow-up to Jesse Vincent's post about September, but this is a really significant piece in its own right. Jesse is one of the most creative users of coding agents (Claude Code in particular) that I know. He's…

Hi — Asad here! Remember those $100M packages for AI researchers? Well, here’s the thing: When comp moves for the builders, it doesn’t take long to move for the sellers, too. So, now we’ve got $100M packages for CROs and enterprise reps clearing $10M a year. I even know a company that hired an SDR…

Open the Slurm launch script for OpenRLHF. It parses node IPs from scontrol show hostnames, hardcodes service addresses, and bootstraps a Ray cluster by hand. Now open the one for veRL. Same thing. NeMo RL? Same thing again. Three unrelated frameworks, three sets of nearly identical glue code, all…

Skills have become one of the most used extension points in Claude Code. They’re flexible, easy to make, and easy to distribute. But this flexibility also makes it hard to know what works best. What type of skills are worth making? How do you structure a skill? When do you share them with others?…

All tests were executed against Kafka 4.2.0 using Dimster (and also validated against 4.3.0). In the last post we measured the overhead that the mechanics of share groups adds, and saw that it is pretty small. Likewise we saw that raw throughput was also comparable to consumer groups and even saw it…

I bought a server this week. Not cloud credits, not a managed platform, not a serverless function bobbing in someone else's abstraction. A single rented box at Hetzner with four cores, eight gigs of RAM, and a name: mercury. By the end of the night it was running every site I care about, including…

We have models solving International Math Olympiad problems, AI writing production code, diagnosing diseases, passing the bar. Yet CEOs of the best startups still can’t tell bookings from revenue from ARR at first glance. Neither can most GPs at venture funds. The journalists covering these…

When I make software, this is my sorted list of priorities: Software should be useful to the end user and strive to become software you can love.Software should be correct, as malfunctioning software detracts from the utility users can derive from it.Software should be maintainable and efficient, in…

This post is about the physical laws of backpressure in software systems, latency death spirals, and why unbounded queues are a bug. If you have ever been on call or in charge of ops and system reliability during a massive traffic spike, you know the feeling. The alerts fire, the CPU goes to 100%,…

Editor’s summary Remote work skyrocketed during the COVID-19 pandemic. Research since has prioritized studying the impact of working remotely on productivity and job satisfaction but neglected other consequences such as loneliness and mental health. Emanuel et al. examined pre- and postpandemic…

6th June 2026 I’ve been experimenting with different approaches to running code in a sandbox for several years now, but my latest attempt feels like it might finally have all of the characteristics I’ve been looking for. I’ve released it as an alpha package called micropython-wasm, and I’m using it…

Last winter, our team went through I-Corps training as part of the NSF's POSE—Pathways to Enable Open-Source Ecosystems—program. I-Corps is the National Science Foundation's customer-discovery training, and POSE adapts it for open-source projects. For us, that meant seven weeks and more than a…

Over the last five years, a new model has emerged: companies that own a specific computing workload and abstract away the underlying infrastructure entirely. The customer pays for the service and never has to think about what's running underneath. The vendor becomes the best in the world at running…

There is great anxiety and uncertainty about AI replacing jobs. How can we move past vague warnings and bombastic predictions and bring data to bear on this question? One good way is to look at the profession where AI capabilities are furthest along and adoption has been exceptionally rapid:…

It’s fifteen years ago (bear with me, I’ve been in this industry since the late 90s, most of my good stories start this way), and you’ve got two senior developers at a SaaS company. One of them writes 40% more lines of code than the other. Is that developer better? More impactful for the business?…

Hi Charity, I'm a senior staff engineer, and I’m wondering what advice you might have for a person in my role in a large company to affect priorities and the speed at which work is "expected" to be executed. It feels like the speed at which the teams are being pushed to deliver was not really…

Tech high priests like Sam Altman and Paul Graham are preaching taste (an idea that has actually been percolating in Silicon Valley for a while). Founders are taking etiquette lessons. Starbucks just announced it is rolling back automation and hiring more baristas because customers want to be served…

An ever-increasing volume of debug investigations, document writing, and code is written by robots. This has created a new etiquette question when working with a team - when is it OK to forward the output of an AI to another human to read? On one hand, an AI with robust integration to internal code…
