Performance results naturally depend on the underlying hardware. The following benchmarks show the execution times for sorting 50 million doubles using different sorting implementations. The measurements were taken on an Apple M1 system using Clang and on an AMD Ryzen 3 Linux system using GCC , both compiled with the…
Undo and redo have been a staple operation of text editors probably since the first typo was ever made, yet there has not been a lot of innovation around refining the idea of what undo and redo could be. Let’s explore what I mean…
Github Renamed Me - We will change your SSH keys and you will like it
What connections are, how they affect our systems, and how and why pooling works.
For most people I interact with, I’m just another text-based program for the most of the time. If input and output are so simple, could I be replaced by the model? For this to work, the model would need to not only understand my writing style but also know a lot about me. The best source for this is my Telegram…
I’ve been watching the Chinese TV show 他来了，请闭眼 (Love Me If You Dare). It’s a good show, kinda reminiscent of the BBC series Sherlock, likewise a crime drama ...
If you had asked me whether or not it was possible to get a 2x speedup for my LazySorted project by adding a single line of code, I would have told you "No way, substantial speedups can really only come from algorithm changes." But surprisingly, I was able to do so by adding a single line using the __builtin_prefetch…
Jorge Silva's personal blog on programming and software engineering
This is a tutorial on building your own shell using Rust, in the spirit of the build-your-own-x list. Creating a shell is a great way to understand how the shell, terminal emulator, and OS work together.
During my recent trip to Vietnam I took the opportunity to visit some schools and see how computer science was taught there. Officially, foreigners require permission from the department of education to enter schools. But it's much simpler (and the results are more representative) to simply show up unannounced. A…
Dmitry.GR: The first complete documentation of Sony Memory Stick from HW to DATA
Let’s explore some basic concepts that will help us create a simple chess AI:
SQLite's optimizer creates indexes automatically to improve query performance with only nested loop joins.
This is a followup to my previous post on the stack monoid, but is intended to be self-contained.
In the previous posts, we've explored the SQLite file format and built a simple SQL parser. It's time to put these pieces together and implement a query…
How does git store different versions of a file? What about a commit? Find out creating your own commit without the help of git.
Personal experience with moving away from Apple's world.
Machine code isn't scary. If you can make sure your JSON conforms to a JSON schema, you can write machine code.
Four years ago today, the Rust async/await feature was released in version 1.39.0. The announcement post says that “this work has been a long time in development – the key ideas for zero-cost futures, for example, were first proposed by Aaron Turon and Alex Crichton in 2016”. It’s now been longer since the release of…
Go is one of my favorite programming languages, but it is still far from perfect.
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…
We think we do, but in fact every web developer will happily sacrifice simplicity to the first shiny thing promising them relief from the mildest of ailments.
