Whether you write compilers, web services or Django admin panels, you probably use hash maps more than all other data structures combined. In fact, you may not remember the last time you used anything else. This is not a coincidence: any conceivable data structure can be implemented with a hash map; therefore, there…
The article should help people to understand the benefits of React and Angular for making an educated decision to choose between Angular or React. It tells my story why I moved from Angular to React after using both libraries for years. It's not just another click-bait article, but an article with lots of experiences…
The macOS command-line tool hdiutil is used to manipulate disk images. From the WHAT'S NEW section of man hdiutil on the latest macOS 27 Golden Gate beta:
The nuance between timestamp with and without time zone
In my never ending quest to have oksh support every C compiler in existence, I sometimes find C compilers in places you wouldn't expect them. Today, I'd like to demonstrate the C compiler built into the Digital Mars D compiler, or DMD for short. Recent versions of DMD have a complete C11 compiler built in named…
Contrary to popular belief, by default, react component doesn't care whether its props changed or not. It will always re-render when its parent renders.
Ben Nadel discusses one of the lessons learned from 10 years of CodePen: solve only problem at a time - a message worth amplifying.
Gödel’s first incompleteness theorem states that there are mathematical statements that can neither be proven or disproven. His proof is fairly difficult to ...
Exploring the computational complexity of chess. Code snippets in Python so you can do the same.
Programmers on the internet often use Turing-completeness terminology. Typically, not being Turing-complete is extolled as a virtue or even a requirement in specific domains. I claim that most such discussions are misinformed --- that not being Turing complete doesn't actually mean what folks want it to mean, and is…
Timsort: A very fast , O(n log n), stable sorting algorithm built for the real world — not constructed in academia. Timsort is a sorting algorithm that is efficient for real-world data and not created in an academic laboratory. Tim Peters created Timsort for the Python programming language in 2001.
The “official” Python Docker image is useful, but to actually understand why, and to use it correctly, it’s worth understanding how exactly it’s constructed.
Intro Espressif Systems released their ESP32-S3 SoC a few years ago, but only recently have they released more documentation and support of ...
How to use the python web scraping framework Scrapy to crawl indeed.com. Learn data engineering strategies for getting actionable insights from public information.
Ever wanted to know how exactly did Quake’s precomputed visibility work? I did, so I wrote vis.py , a reimplementation of their algorithm in Python. This guide has all the information you need to understand vis , the tool used by Quake, Half-Life and Source Engine games.
Some time ago, I came across the Wikipedia article of Niels Henrik Abel , and something there burnt its way into my mind. Abel changed the face of mathematics, despite dying at 27. And here comes the thing – I give the mic to Wikipedia now:
Wayland is all the rage those days. Distributions left and right switch to it, many readers of my previous article on writing a X11 GUI from scratch in x86_64 assembly asked for a follow-up article about Wayland, and I now run Wayland on my desktop. So here we go, let's write a (very simple) GUI program with Wayland…
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
As I continue reading An Introduction to Parallel Programming, I cannot help but notice a connection between communication among processors, communication among human beings, and communication within the individual self....
I recently wanted to take a hierarchy of items and draw them in a nice tree structure. For example, a Family Tree. At the time, I thought “This will be easy, I’ll just Google for an alg…
Clarifying the shebang (#!) mechanism: A step-by-step look using strace and kernel code shows how Linux handles script execution directly, revealing the shell isn't involved initially.
Manipulating actually-big-data is just as easy as performing an analysis on a dataset with only a few records.
A post by Eshel Yaron introducing the Emacs Trust Manager
Okay, promises, promises. Here's the first of my bucket list projects I'm completing which I've intermittently worked on for literally two d...
I recently released papaya, a fast and feature-complete concurrent hash table for Rust. In this post I want to dive into the design and research that went into creating it, as well as why you might consider using it over existing solutions.
