Jepsen: Bufstream 0.1

Background Kafka is a popular streaming system which provides replicated, sharded, append-only logs. Bufstream is a drop-in replacement for Kafka designed to prioritize data governance and cost efficiency in cloud environments. Like Kafka, Bufstream provides a collection of named, partially ordered logs called topics. Each topic is divided into partitions. Each partition is a totally ordered, append-only list of records (also called...
What I wish someone told me about Postgres

I’ve been working professionally for the better part of a decade on web apps and, in that time, I’ve had to learn how to use a lot of different systems and tools. During that education, I found that the official documentation typically proved to be the most helpful. Except…Postgres. It’s not because the official docs aren’t stellar (they are!)–they’re just massive. For the current...
Functors to Monads: A Story of Shapes

For many years now I’ve been using a mental model and intuition that has guided me well for understanding and teaching and using functors, applicatives, monads, and other related Haskell abstractions, as well as for approaching learning new ones. Sometimes when teaching Haskell I talk about this concept and assume everyone already has heard it, but I realize that it’s...
Locking Mechanisms in High-Load Systems

In the world of concurrent systems, especially when we're dealing with high-load distributed environments, finding a balance between data consistency and system performance is a constant headache. The main catch here is synchronization mechanisms, especially locks. These guys ensure that processes don't step on each other's toes when sharing resources. In this blog post, let's break down what locks are,...

OpenAI's new "Orion" model reportedly shows small gains over GPT-4

Language model development seems to have hit a ceiling. OpenAI's upcoming Orion model barely outperforms GPT-4, its predecessor, according to a new report. This slowdown affects the entire AI industry. The Information reports that OpenAI's next major language model, codenamed "Orion," delivers much smaller performance gains than expected. The quality improvement between GPT-4 and Orion is notably less significant than what...
