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 .

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…

On mutex performance and WTF::Lock
One of the things I’ve been doing this quarter is removing Gecko’s dependence on NSPR locks . Gecko’s (non-recursive) mutexes and condition variables now use platform-specific constructs, rather than indirecting through NSPR. This change makes things smaller, especially on POSIX platforms, and uses no dynamic memory…

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…

GCC 5.1 released
Command-line optimization and target options are now streamed on a per-function basis and honored by the link-time optimizer. This change makes link-time optimization a more transparent replacement of per-file optimizations. It is now possible to build projects that require different optimization settings for…

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
