We've been buying servers from Dell since the 2000s at 37signals , but I was never too impressed with their personal computers. They either felt cheap or enterprisey to me. Like they were made exclusively for people who are handed standard-issue laptops by corporate, and not…
On this hot summer’s day in Basel, Switzerland, the seventh HTTP workshop started. These events tend to work roughly the same way and the people in the room are also to large extent familiar and known since previous editions. Forty people in a meeting room, where we take turns…
AI made our pull requests 3.5x bigger, but our defect detection dropped. PR data from two projects shows what happens to code quality when AI writes the code. The post We 3.5x’d Our Pull Requests with AI: Now We Catch Fewer Bugs appeared first on Pawel Brodzinski on Leadership…
Towards the end of 2025, it seemed that we couldn’t get through a week at Provet without some kind of infrastructure degradation. Outages were piling up, they were hard to diagnose, and customers were losing patience. When a major AWS outage hit in October, our customers didn’t…
What does this mean?
LLMs generate code incredibly fast, but to ensure they generate exactly what is intended, they need clear boundaries. Abstractions and Domain-Specific Languages (DSLs) provide a strong harness that guides LLMs right from the start. Unmesh Joshi describes how the example of…
To be brutally honest, this (making Claude my social media manager) all started because I felt inadequate about self-promotion. And being an engineer, my response to feeling bad about something is to ask what I can build and what data would make the feeling go away. So at the…
It had nothing to do with software engineering.
Your “Bluesky account” is not just a Bluesky account: it is an account that can be used with a variety of other applications. This post is going to be an exploration of part of what that means from a technical perspective, so if you’re not a software developer, this post isn’t…
TL;DR: is your refrigerator running malware? If so, you better catch it!
A presigned URL is a replay attack you did on purpose. Replayable auth tokens are the textbook way to create vulnerable systems, but Tigris ships them as a first-class feature with presigned URLs and so does every other object storage system on the planet. However this isn't an…
Taste used to be a byproduct of the reps. Agents took the reps. So if you're junior you now have to go get the taste and judgment on purpose. A builder's look at the weakening entry level, the two debts we now owe, and concrete ways to build judgment when the machine writes the…
