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 .
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
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…
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...
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.
Yeah, so about that OpenPOWER Minimum Viable Product JavaScript JIT for Firefox. This happened (all timings from an unoptimized debug build ...
How I got nerd sniped into benchmarking legacy x86 instructions
You might have heard people say that functional programming is more academic, and real engineering is done in imperative style. I’m going to show you that real engineering is functional, and …
Git ls-files is up to 5 times faster than fd or find in this benchmark, but why?
Native-like Navigation for Web apps
A year ago I wrote a post comparing .NET 5 performance with its predecessor on Fusion performance tests, and honestly, I was quite…
List of all the plugins I use in PyCharm and Idea.
Sedano et al (2017)[1] on "Software Development Waste" identified and describe that software projects manifest nine possible types of waste, in terms of loss of productivity and unnecessary friction.
“JPEG” or the image encoding specification by the “Joint Photographic Experts Group” (JPEG) is a truly universal format at this stage. You really cannot go very far on the internet without seeing a JPEG file. The amount of content encoded in JPEGs must be surely biblical by now. If there is one thing that is going to…
Supply chains attacks are all the rage these days, whether to deliver RATs, cryptocurrencies miners, or credential stealers. In Rust, packages are called crates and are (most of the time) hosted on a central repository: https://crates.io for better discoverability. We are going to study 8 techniques to achieve Remote…
What is a Container? Container vs. VM? Docker vs. Kubernetes. How to organize the learning efficiently?
This is a little sed challenge that ocurred to me somewhat recently, when I wondered how many weeks were between 2 dates. Of course, I just looked at the calendar and counted, but then I wondered what kind of sed script I’d need in the middle of a cal -y | ... | wc -l pipeline to get the same answer.
