I had my fair share in designing and building large systems. I've taken part in rewriting Uber's distributed payment systems [https://blog.pragmaticengineer.com/distributed-architecture-concepts-i-have-learned-while-building-payments-systems/] , designing and shipping Skype on Xbox One and open-sourcing RIBs…
When we implemented the git portion of Sublime Merge , we chose to use mmap for reading git object files. This turned out to be considerably more difficult than we had first thought. Using mmap in desktop applications has some serious caveats, and here's why:
Full engine for the Wolfram Language can be deployed on any system--and called from programs, languages, web servers. Available for anyone to download, for free, to use in their software development projects.
I’ve written about lots of computer vision and machine learning projects like object recognition systems and face recognition projects. I…
Long ago, on Svalbard, when you were a young witch of forty-three, your mother took your unscarred wrists in her hands, and spoke:
A new edition of the book Modern C and much more are now available under a CC license via the following page This edition is the result of a collaboration with Manning, and improves a lot over the…
This post introduces paging, a very common memory management scheme that we will also use for our operating system. It explains why memory isolation i…
This article is based on historical research and on simply reading the Vim user manual cover to cover. Hopefully these notes will help you (re?)discover core functionality of the editor, so you can abandon pre-packaged vimrc files and use plugins more thoughtfully.
Client-side navigation is supposed to make your pages load faster. But when I tried it, it was actually slower! Why?

For my ten years in the Erlang community, I decided to cover a few topics such as hype phases and how this related to Erlang, the ladder of ideas within the language and how that can impact adoption, what changed in my decade there, and what I think Erlang still has to bring to the programming community at large.
In 1963, the philosopher Edmund Gettier published a three-page paper in the journal Analysis that quickly became a classic in the field. Epistemologists going back to the Greeks had debated what it meant to know something, and in the Enlightenment, a definition was settled upon: to know something is to have a…
It's well known that if you drag a file from Finder and drop it into Terminal, the full path of the file will output in Terminal. The same behavior occurs with copy and paste too. This has always been a very convenient but innocuous operation… until macOS 10.15 Catalina. I've discovered that on Catalina, pasting a…
In which I lament the fact that many frontend Web engineers don't understand the end product of their work, HTML.
قلب is a programming language exploring the role of human culture in coding. Code is written entirely in Arabic, highlighting cultural biases of computer science and challenging the assumptions we make about programming. It is implemented as a tree-walking language interpreter in JavaScript.
I had the opportunity to work on scaling a React rendering service, adapting a fixed hardware provision to deal with increasing load. Over the course of many months, incremental improvements were made to the system to enable it to cope with demand. I thought it might be useful to share the more interesting insights…
In the previous post we described the Firewall Rules architecture and how the different components are integrated together. We created a configurable Rust library for writing and executing Wireshark®-like filters in different parts of our stack written in Go, Lua, C, C++ and JavaScript Workers.
In this article, we explain how to scale Elixir to handle 100k connections per second.
Rendering text, how hard could it be? As it turns out, incredibly hard! To my knowledge, literally no system renders text “perfectly”. It’s all best-effort, although some efforts are more important than others.
