Ruby concurrency is hard: how I became a Ruby on Rails contributor
For the past several weeks, I've been trying to fix a cranky spec in Karafka integrations suite, which in the end, lead me to become a Ruby on Rails micro-contributor and submitting similar fix to several other high-popularity projects from the Ruby ecosystem. Here's my story of trying to make sense of my specs and […]

Map Data: False Assumptions
Famously, engineers tend to make wrong assumptions about a lot of things: Names and time are two well-known examples. Maps are a rich source of edge cases. Especially when you start dealing with gl…

Delimiter-first code
A new top-level syntax for programming languages is proposed to show advantages of this method. New syntax is arguably as simple, but more consistent, better preserves visual structure and solves some issues in code formatting.

ML code generation vs. coding by hand: what we think programming will look like
Will ML code generation like GitHub Copilot replace coding by hand? We say no: developers still maintain generated code, so abstraction matters.

Jax vs. Julia (Vs PyTorch)
A while ago there was an interesting thread on the Julia Discourse about the “state of machine learning in Julia”. I posted a response discussing the differences between Julia and Python (both JAX and PyTorch), and it seemed to be really well received! Since then this topic seems to keep coming up, so I thought I’d…

JEP 431: Sequenced Collections
Introduce new interfaces to represent collections with a defined encounter order. Each such collection has a well-defined first element, second element, and so forth, up to the last element. It also provides uniform APIs for accessing its first and last elements, and for processing its elements in reverse order.

Devious SQL: Message Queuing Using Native PostgreSQL
An interesting question came up on the postgresql IRC channel about how to use native PostgreSQL features to handle some sort of queuing behavior. While the specific usage was related to handling serialization of specific events to some external broker, the specifics are less important than the overall structure.

What Is Rust's Unsafe? (2019)
I’ve seen a lot of misconceptions around what the unsafe keyword means for the utility and validity of Rust and its marketing as a “safe systems language”. The truth is a lot more complicated than a single pithy tweet can possibly sum up, unfortunately; here it is as I see it.

How to JIT – An Introduction
When I wrote the introductory article for libjit , I aimed it at programmers who know what JITs are, at least to some extent. I did mention what a JIT is, but only very briefly. The purpose of this article is to provide a better introductory overview of JITing, with code samples that don't rely on any libraries.
