Fifty problems with standard web APIs in 2025
Recently, I made a free game . It's a little mystery investigation game which I was inspired to write after enjoying games like Case of the Golden Idol , Roottrees are Dead , and Return of the Obra Dinn . I thought my UX ideas were pretty simple, so I decided to implement it in HTML5 .

I spent a year building an Android course for the elderly
This is my story about an adventure into online teaching, video course making, and choosing a hard-to-reach audience, who desperately needs help.

Curl doesn’t spew binary anymore
One of the least favorite habits of curl during all these years, I've been told, is when users forget to instruct the command line tool where to store the downloaded file and as a direct consequence, curl instead sends a lot of binary "gunk" to the terminal. The end result of that is at best … Continue reading curl…

Go 1.18 will embed source version information into binaries
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

Windows 3.1 All Over Again
Reactive programming and thread sharing. Javascript, Node.js, Go, Rails, Elixir and Erlang. Rewind the clocks to Windows 3.1 In 1992 with Windows 3.1 we had this thing non-preemptive multitasking, i.e. “Cooperative Multitasking”. Cooperation is a funny term, it should actually be “Programmer Controlled Multitasking”…

Think in math, write in code (2019)
Programmers love to discuss programming languages. We not only debate their technical merits and aesthetic qualities, but they become integrated into our personal identities, along with the values and traits that we associate with them. Some even defend a form of Linguistic Determinism that thinking is confined to…

Speculating the entire x86-64 instruction set in seconds with one weird trick
As cheesy as the title sounds, I promise it cannot beat the cheesiness of the technique I’ll be telling you about in this post. The morning I saw Mark …

I wrote a linker everyone can understand
When we wrote our assembler we made many design choices that helped us cut down on the complexity of the assembler itself. One of those decisions was to have the assembler directly output executables. That was a good choice in that it allowed us to quickly test as we were developing: once we implemented an opcode, we…

Counting Things in Python: A History
Sometimes the Pythonic way to solve a problem changes over time. As Python has evolved, so has the Pythonic way to count list items. Let’s look at...

Using Fourier Transforms to Multiply Numbers
The purpose of this article is to show you step-by-step examples of how to use the Fourier transform algorithm to multiply two numbers. The primary advantage of using fourier transforms to multiply numbers is that you can use the asymptotically much faster 'Fast Fourier Transform algorithm', to achieve better…

Reverse-Engineering YouTube: Revisited
Back in 2017 I wrote an article in which I attempted to explain how YouTube works under the hood, how it serves streams to the client, and also how you can exploit that knowledge to download videos from the site. The primary goal of that write-up was to…

Programming Books You Wish You Read Earlier
There are so many programming books out there, sometimes it's hard to know what books are best. You won't find cracking the coding interview, the pragmatic programmer, or even the best python book. These are the best programming books curated from each major Software field.

Neural network from scratch
In this edition of Napkin Math, we’ll invoke the spirit of the Napkin Math series to establish a mental model for how a neural network works by building one from scratch. In a future issue we will do napkin math on performance, as establishing the first-principle understanding is plenty of ground to cover for today!

Swift Achieved Dynamic Linking Where Rust Couldn't (2019)
For those who don’t follow Swift’s development, ABI stability has been one of its most ambitious projects and possibly it’s defining feature, and it finally shipped in Swift 5 . The result is something I find endlessly fascinating, because I think Swift has pushed the notion of ABI stability farther than any language…

Emacs 26 Brings Generators and Threads
Emacs 26.1 was recently released . As you would expect from a major release, it comes with lots of new goodies. Being a bit of an Emacs Lisp enthusiast , the two most interesting new features are generators ( iter ) and native threads ( thread ).
