Summary: Wuffs’ PNG image decoder is memory-safe but can also clock between 1.22x and 2.75x faster than libpng , the widely used open source C implementation. It’s also faster than the libspng , lodepng and stb_image C libraries as well as the most popular Go and Rust PNG libraries. High performance is achieved by…
A basic introduction to Western music theory using the Python programming language to derive scales, chords, and modes in every key.
After I wrote most of this blog post the night of October, 5th 2021 I wasn't sure I would post it. After the events of the last 36 hours, I felt I needed to capture my experience on my website where it can only be edited by me. After reading this, I hope you will have a clear set of datapoints from my point of view…
I’ve been lurking the fish shell for a couple of years now (and the nushell but it is another story for another time). Not so long ago, I decided to try it, and it’s simply… amazing. If I had to state one feature that makes me like to use it, it’ll be the autocompletion, hands down. It’s the first time I just take a…
I love a good bug, especially ones that are initially hard to explain but then ...
This article summarizes some lower level aspect of how GPU executes. Although GPU programming is not that complicated when compared to CPU, it also doesn’t match to what hardware is doing exactly. The reason is that we can’t just program GPU without some API, which is an abstraction over its inner workings. Since few…
Performance comparison of counting and sorting word frequencies in various languages (Python, Go, C++, C, AWK, Forth, and Rust)
Writing your own TCP/IP stack may seem like a daunting task. Indeed, TCP has accumulated many specifications over its lifetime of more than thirty years. The core specification, however, is seemingly compact[^tcp-roadmap] - the important parts being TCP header parsing, the state machine, congestion control and…
Over the last few years, the software development community’s love affair with the popular open-source relational database has reached a…
No matter what language you program in or what applications you use: everything you do with a computer today is powered at some level by a piece of C/C++ code.
I've been using Bash functions quite liberally over the past couple years, but last week I discovered that they can be much better than I thought. In this post, I'll explain how I thought they worked, why I was wrong, and how that makes them better.Function syntax
I have been working at Facebook as a software engineer for a while now. During this time, I have got different inquiries from friends and…
Detailed look into all the machinery involved in rendering Emoji
Comparing the core values of our text editors, describing the history of Neovim's development, and discussing the rise of VSCode.
Crusader Kings III is a pretty impressive game. It’s impressive not only for its official content, but also for its extensive modding…
How does AWS Lambda work under the hood? Let's find out together!
There are a whole bunch of popular interview questions that can be solved in one of two ways: Either using common data structures and algorithms in a sensible manner, or by using some properties of...
To be successful at digital transformation you need to optimize the key feedback loops in your software engineering organization
Hey, that took only a month, which means that it’s time, once again, to display some Emacs charts. And since this is the tenth post in this series, I thought I’d natter on even more tha…
I'm certainly not a world-class expert, but I have put my 10,000 hours of deliberate practice into programming. Here are 31 of my reflections on programming.
At this point, most developers use Git as a tool for collaboration. We have our rote-learned commands to pull, commit, and push. And of course, there's that one coworker who knows a bit more about Git…
...though it's not the flagship borrow checking that's at fault. What I noticed, and would like to share with you today, is that the exhaustiveness checking performed by the Rust compiler on match patterns is a superset of the SAT problem.…
In shell scripting you sometimes come across comparisons where each value is prefixed with "x". Here are some examples from GitHub:
I am very proud to say that after about 10 months of work I finished writing my Emacs Lisp book . If you haven’t heard of it yet, it’s called “Hacking your way around in Emacs” and it is an intermediate-level textbook on Emacs Lisp, showing a lot of useful things on about 100 pages.
It's common for me to get excited about a personal project, put a bunch of time into it, and then lose interest. As much as possible, I want these projects to continue working; upkeep isn't fun. What does designing for minimum maintenance look like? The biggest piece is minimizing your dependencies, and limiting them…
