Unfinished Business with Postgres
7 years ago I left Heroku. Heroku has had a lot of discussion over the past weeks about its demise, whether it was a success or failure, and the current state.

Sabotage
In many places it seems to have become the norm to celebrate overwork, sleep deprivation and chronic stress. Ordinarily if you reveal that you are unhappy, unproductive and causing yourself mental and physical harm, people will be concerned and try to intervene.

In particular, there wasn’t a lot of information about A* on the web, so I decided to collect all my notes about pathfinding [1] together in one place in the 1990s. But then in the 2010s I started making…

Roguelike Tutorial: Up-to-Date and Literate
Started on 9th May, 2019 it took almost five months to finish. It again puts the tutorial in a place I am happy with for now, and it will likely stay there for quite some time. Given the priorities and circumstances in my life, I don’t expect to keep working on it for time to come.

Reducing the maximum latency of a bound buffer in Erlang
Recently I came across two great articles on the Pusher blog: Low latency, large working set, and GHC’s garbage collector: pick two of three and Golang’s Real-time GC in Theory and Practice . The articles tell the story of how Pusher engineers reimplemented their message bus. The first take was done in Haskell. During…

Over the new year holiday time I had a chance to get away from it all, and snuck up to Finland to sit in a lodge on the Gulf of Finland, sip coffee, take saunas and read. I brought along a few books, the only programming one being Brian W …

This is an interactive tutorial series about Conflict-Free Replicated Data Types, or CRDTs for short. Their purpose is to allow seamless replication of data on different nodes in a distributed system. Merging is by construction always possible, without any conflicts. This series assumes no knowledge about CRDTs, but…
