I scrape Arxiv to find underused Greek variables which can add some diversity to math; the top 10 underused letters are ϰ, ς, υ, ϖ, Υ, Ξ, ι, ϱ, ϑ, & Π. Avoid overused letters like λ, and spice up your next paper with some memorable variables!
A complete list of SQLite releases in a single page and a chronology are both also available. A detailed history of every check-in is available at SQLite version control site .
A while ago, I was curious how the speed of document.getElementById compared to document.querySelector in Javascript for selecting a single element by ID. querySelector has to do a lot more work, so one would expect that it would be slower, but I didn't know if the difference was enough to care about.
PHP 8.1 is a major update of the PHP language. Enums, readonly properties, first-class callable syntax, fibers, intersection types, performance improvements and more.
With the unprecedented advances of modern machine learning comes the tantalizing possibility of smart data-driven autonomous systems across a broad range of real-world settings. However, is machine learning (especially deep learning) really ready to be deployed in safety-critical systems?
Emacs has a reputation for being borderline unusable out of the box, of being bloated but somehow surprisingly bare. This is largely a discoverability problem1. The solution the Internet has settled on seems to be “Emacs distributions” like Doom, Spacemacs or Prelude that glue together dozens (sometimes hundreds) of…
Depend on abstractions, not on concretions
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…
2024 Update: Part 2 is out! Let’s make a gzipped file and see what’s in it. We’ll keep it simple: just write 8 ‘a’s to a file. $ echo "aaaaaaaa" > test.out $ xxd test.out 00000000: 6161 6161 6161 6161 0a aaaaaaaa. As we can see, our file is 9 bytes long. We have 8 ‘a’ bytes written, plus a Line Feed (LF) character…
JDK 17 has been out for a few months and it’s not just packed with new language features. The performance boost compared to older JDK versions is also really significant. It becomes especially clear when compared to the previous LTS releases, JDK 8 and JDK 11. Much of the improved performance comes from new features…
Introducing QOI — the Quite OK Image Format . It losslessly compresses RGB and RGBA images to a similar size of PNG, while offering a 20x-50x speedup in compression and 3x-4x speedup in decompression. All single-threaded, no SIMD. It's also stupidly simple .
Ever wondered what browsers do to get JavaScript to execute quickly? Let’s take a look.
I talk about tree sitter, CEDET, and Combobulate -- my "paredit-style" package that's designed to work with most programming languages.
What the creators of Processing — now 20 years old — did right
Collaboration on rich text is hard to model with plain-text approaches. We review the challenges and how to construct a CRDT for rich text.
How we developed Oso to let you query your database using your authorization policy.
The intended audience for this article is undergrad students who already have a good grasp of Java, or seasoned Java developers who would like to explore an in-depth analysis of various hash table implementations that use Open Addressing. The reader should be familiar with Java generics, collections, basic data…
Building a modern front end in Django without reaching for a full-blown JavaScript framework. Choosing the right tools for the job, and bringing them into your project.
5 bash tricks I find myself using often that I wish I'd discovered sooner.
The code for this post is at my Github repository: github.com/arxanas/detect-recruiter-spam. However, I have not included my pre-trained model, since it cont...
In this essay, Carson Gross explores HATEOAS (Hypermedia as the Engine of Application State), explaining how it enables REST APIs through hypermedia responses and contrasting it with modern JSON-based APIs. Using clear HTML examples, Carson demonstrates how HATEOAS allows clients to discover available actions…
Learn how to use PostgreSQL with the Go programming language using the pgx driver and toolkit in a very productive manner. Furthermore, with the provided source code, you'll be able to learn how to write efficient and sound unit and integration tests, ready to be run locally or on a Continuous Integration environment…
This paper appears in Advances in Exception Handling Techniques , edited by A. Romanovsky, C. Dony, J.L. Knudsen, and A. Tripathi. This book, published in 2001, is part of Lecture Notes in Computer Science, Volume 2022 , published by Springer .
I’ll be walking you step by step on how I built a bare-metal, 3-node Kubernetes cluster running on Raspberry Pi. I'll also share some tips and tricks I learned along the way.
Can we move our development environment from our local machines to a remote server, and interact with it through a browser-mediated IDE?
It's like a Let's Play, but for obscure software documentation. I tried to learn Nix, and it was pretty hard. I kept a diary of every command I tried, every wrong assumption that I made, and every realization that I had along the way.
