I started RavenDB in a spare bedroom, because of a problem that wouldn't let me sleep.

I’m currently working on a pretty deep optimization cycle in how RavenDB and Voron (its storage engine) handle I/O.

A while ago, MongoDB purchased VoyageAI for 220 million dollars.

About twenty years ago, I was working on what would eventually become RavenDB, and I needed an engine to handle queries.

I've written before about why I think the “modern” approach of solving every problem by adding agents is a doomed path.

Everyone talking about coding models fixates on the same number: how fast the thing generates code.

I am looking into some regex work, and I ran into a performance problem.

Deep in the heart of Corax (RavenDB’s querying engine), everything deals with something called a Posting List.

I still remember the bookstore.

In the 2000s, the hottest move in software was offshoring.

I’m convinced that in hell, there is a special place dedicated to making engineers fix flaky tests.

No, the title is not a mistake, nor did I use my time travel pass to give you insights from the future.

One of our team leads has been working on a major feature using Claude Code.

You read the story a hundred times: “I told Codex (or Claude, or Antigravity, etc.) to build me a full app to run my business, and 30 minutes later, it’s done”.

Like everything else, we have been using AI in various forms for a while now, from asking ChatGPT to write a function to asking it to explain an error, then graduating to running it on our code in the IDE, and finally to full-blown independent coding assi…

I have run into this post by John Rush, which I found really interesting, mostly because I so vehemently disagree with it.

I am working a bit with sparse files, and I need to output the list of holes in my file.

I needed to export all the messages from one of our Slack channels.

Modern coding agents can generate a lot of code very quickly.What once consumed days or weeks of a person’s time is now a simple matter of a prompt and a coffee break.The question is whether this changes any of the fundamental principles ofsoftware develo…
