Whether it be with React, VueJS, Angular, or in Rust, modern web applications are composed of 3 kinds of pieces: Components Pages Service Components are reusable pieces and UI elements. An input field, or a button, for example. Pages are assemblies of components. They match routes (URLs). For example, the
What can software learn from Christopher Alexander? Many programmers know that the idea of design patterns comes from architecture, but Christopher Alexander's writing has much more for us than just the Gang of Four design patterns. This post is a somewhat assorted collection of ideas for better software and…

Node.js® is a free, open-source, cross-platform JavaScript runtime environment that lets developers create servers, web apps, command line tools and scripts.
Announcing urllib3's bounty program The urllib3 team is excited to announce the start of our bounty program! We’ve recognized that one of the biggest challenges to shipping v2.0 is not having e...
I’ve had numerous requests for a guide to building BasiliskII on iOS. Let me know of anything is unclear or would benefit from more details!

How I sped up GoAWK by switching from a tree-walking interpreter to a bytecode compiler and virtual machine interpreter.
In Emacs version 28 Emacs developers introduced so-called read symbol shorthands. If you’re interested in the rationale, feel free to search the Emacs developer mailing list for the discussion. However, it does seem that not everyone likes the idea of shorthands as a substitution for namespaces (or packages, if you’re…
Towards the end of last year, I switched from working on PHP at JetBrains, to working on LLVM at Red Hat. While it was already under discussion beforehand, this catalyzed the creation of the PHP foundation , which now pays multiple people to work on PHP. Special thanks for this go to Roman Pronskiy, who did most of…
We announce and explore the possibilities for bringing set-theoretic types into Elixir.
I defined a QT Object that contains an integer value and uses QT signal along with awl::Observable based on virtual functions to notify the subscribers when the value changes:
I still have my Nokia 5800 lying around. It runs Symbian. That platform is quite different from Android. For one thing the internal storage size is 81 MB - less than what your single android app takes up, even in RAM, and it works faster than modern smartphones - e.g. the SMS app opens instantaneously. Another…
(Most) C++ implementations provide at least 8, 16, 32, and 64-bit signed and unsigned integer types. There are annoying implicit conversions, discussions about undefined behavior on overflow (some think it’s too much UB, others think it’s not enough), but for the most part they do the job well. Newer languages like…
Falling out of love with warp Back when I wrote this codebase, warp was the best / only alternative for something relatively high-level on top of hyper. I was never super fond of warp’s model — it’...
The Year of the Brutal Desktop
Recently, Aria Beingessner published an interesting essay “ Rust’s Unsafe Pointer Types Need An Overhaul ”. There are several parts to this essay, all of which address issues which cause me pain in Rust, and which I would love to see fixed. I want to focus on one issue: Rust’s usize conflates address, data, and object…
I'm currently working on a macOS app that's built with Racket and allows the user to write small scripts to process and filter some data. While Racket is definitely my preferred language and I could easily use it for these scripts, my target audience for this app would probably appreciate a more familiar language. I…
I have done a few previous blog posts on who has contributed to PostgreSQL , but I did not do one last year. A couple people mentioned to me...
A technical recruiter, having discovered that that the ways of Unix hackers were strange to him, sought an audience with Master Foo to learn more about the Way. Master Foo met the recruiter in the HR offices of a large firm.
Code level discussion of web scraping, gray hat automation, growth hacking and bounty hunting
In this talk, Andrew Hyatt shows how to use SQLite to store and retrieve information using the triples package. Afterwards, he wil handle questions over BigBlueButton.
Pair programming is where two programmers work together on a single computer. One writes the code, while the other observes and offers suggestions. I'm not talking about debugging or brainstorming together, but this p...
Some may think Fortran is an archaic language, and certainly not one that should be taught, but in any respects modern Fortran is an exceptionally good language to teach programming in. Certainly b…
