Shrink Go binaries 7x with this one weird trick
Ok, I lied, there’s no weird trick. However, you can easily reduce a Go binary size by more than 6 times with some flags and common tools.

The Problem with Macros
So we’re supposed to be writing a game, right? But in order to make progress, we have to fix a bug. And in order to fix the bug, we have to write a test. And in order to write a test, we have to write a test framework. And in order to write a test framework, we have to understand a thing or two about macros. Okay. So…

Things I like about Gleam's Syntax
Gleam is a Type-Safe programming language that transpiles to Erlang And javascript . , so you can run its code on the BEAM. I’ve slept on Gleam for a while because its syntax. It was too much Rust and not enough Elixir for me.

Architecture of a Real World Haskell Application
There were numerous posts on reddit, SO and the like which were asking for how to architect real world Haskell applications. Well, this is my go at it for an in-house testing tool which is used extensively. I would not claim myself an advanced Haskeller, some of the code is probably not idiomatic Haskell (and also…

Lush: My favorite small programming language
I meant to write about this when I started my blog in 2009. Eventually Lush kind of faded out of my consciousness, as it was a lot easier to get work doing stuff in R or Matlab or whatever. The guy…

Python's Type Checking Renaissance
You may have heard that TypeScript has been taking the web development space by storm in the last few years , bringing to it static types. I believe the same thing is starting to happen in the world of Python, where type checkers like mypy , Pyre , and Pyright are increasingly used, at least where Python is used by…

The cost of Go's panic and recover
TL;DR ¶ Some of the wisdom contained in Josh Bloch’s Effective Java book is relevant to Go. panic and recover are best reserved for exceptional circumstances. Reliance on panic and recover can noticeably slow down execution, incurs heap allocations, and precludes inlining. Internal handling of failure cases via panic…

strcpy: A niche function you don't need
The C strcpy function is a common sight in typical C programs. It’s also a source of buffer overflow defects, so linters and code reviewers commonly recommend alternatives such as strncpy (difficult to use correctly; mismatched semantics), strlcpy (non-standard, flawed ), or C11’s optional strcpy_s ( no correct or…

Why Elixir (2014)
It’s been about a year since I’ve started using Elixir. Originally, I intended to use the language only for blogging purposes, thinking it could help me better illustrate benefits of Erlang Virtual Machine (EVM). However, I was immediately fascinated with what the language brings to the table, and very quickly…

The Strict Aliasing Situation Is Pretty Bad
One thing that works well in practice in cases where you really don’t want to process single bytes at a time is to use a union for going from one type to another. Granted, writing one member of a union and reading from a different one also isn’t allowed per the standard, but every compiler I’ve come across allows it…
