Zig or Go: How I Choose. When I pick Go and when I pick Zig: Garbage Collector vs allocators, goroutines vs threads, binary size and stability. mtsoukalos.eu/2026/10/zig-or… #ziglang #golang @golang

Zig or Go: How I Choose

I have written several books on Go and one on Zig, so every time I start something new I have to decide which of the two to use. The answer is not always the same and I do not think one language is...

My latest blog post is about Zig memory allocators. Read it at mtsoukalos.eu/2026/10/alloca… #ziglang #Zig #SystemsProgramming

Allocators in Zig: Which One and When

In Zig every function that needs heap memory takes an allocator as a parameter and you decide which one to give it. When I started with Zig this was my first real question, because the Standard...

My latest blog post is about the go list -json option. Learn how to get package data out of the Go tool. Read it at mtsoukalos.eu/2026/10/the-go… #golang @golang

The go list -json Option

After The go -x Option I wanted to write about another Go flag that I use more than I expected to. The go list command prints the import paths of the packages you give it and most people never go...

How to use Command Line Arguments in Zig. How std.process.Init hands you the arguments in Zig 0.17, why toSlice() wants an arena and how to walk them with an iterator and no allocator at all. mtsoukalos.eu/2026/10/comman… #ziglang #Zig #SystemsProgramming

Command Line Arguments in Zig

Most of the Zig programs on this blog begin with the same line that reads the command line arguments and I have never explained it. This post is about that line, what it gives you back and what you...

In my latest blog post, I discuss What Developers Can Learn from the Odyssey: mtsoukalos.eu/2026/10/what-d… #BooksWorthReading #BookRecommendations #Homer #Odyssey #SoftwareDevelopment

What Developers Can Learn from the Odyssey

In Developers Should Read the Classics Too I started with Homer and then never came back to him. Six Classics You Can Finish in a Weekend left him out because the Odyssey is not a weekend book. It...

My latest blog post: Hash Maps in Zig: mtsoukalos.eu/2026/10/hash-m… #ziglang #Zig #SystemsProgramming #programming Enjoy!

Hash Maps in Zig

After Using Array List in Zig, the next data structure that I reach for is the hash map. The Zig standard library has several of them and the names can be confusing, so I will start with the one you...

What Developers Can Learn from the New Testament

This is the second part of What Developers Can Learn from the Old Testament. The New Testament is a much shorter book. It has four accounts of the life of Jesus, one book about the first years after...

The Tower of Babel failed because people stopped understanding each other. Moses had to learn to delegate. Gideon won with 300 people, not 32,000. I wrote a post about what developers can learn from the Old Testament: mtsoukalos.eu/2026/10/what-d…

What Developers Can Learn from the Old Testament

When I wrote Developers Should Read the Classics Too I went from Homer to Plato to Dostoevsky and left out the most printed book of all. Most developers I know have not opened a Bible since school,...

Developers Should Read the Classics Too

Most of what I post here is about Go and Zig. Two weeks ago I posted 21 Ideas from The Black Swan, which has no code in it at all, and it made me think about how little non-technical reading most...
