Not all instructions on modern processors cost the same. Additions and subtractions are cheaper than multiplications which are themselves cheaper than divisions. For this reason, compilers frequently replace division instructions by multiplications. Roughly speaking, it works in this manner. Suppose that you want to…
This is insane: more than 28,000 visitors came to read Part I of “HFT in my backyard”. Some of them are inevitably bots, but my logs reveal the majority to be human readers from bank desks, technol…

It's not about technology for its own sake. It's about being able to implement your ideas.
Ah, Zig . I have a love-hate relationship with this one. A “new” (reading: appeared a couple years ago , already — yes, already ), language with high ambitions. Zig was made to run at low-level, with a simple design to solve many problems C has (macros, allocators, error handling, more powerful types like baked-in…
The "Waterfall" methodology was a historic accident and they knew it.
In this blog post, we'll examine the virtualization obfuscation used by Nike
Almost nobody understands how traceroute works. Worse, it's not a real tool
This here is the epitome of craziness. I could very well give up my search for more scary things in Emacs because I very much doubt I’ll find anything more fear-inducing, but first of all, let’s explain what’s wrong with it. Unlike my previous examples it’s not something I can show you by just pointing at code…

VS Code collects telemetry data to help understand Microsoft how to improve the product. Is it above board? Can I turn it off completely?
A guide to all the Magic Methods in Python
This summer, cruising down the I-5 through California’s Central Valley to the Los Angeles Basin, I unwittingly stumbled upon a most exasperating development: the country strip mall . First, let me state that I don’t hate. I’ve got nothing against Petco, Starbucks, OfficeMax, et al. When overcome by the desire for a…
See A Satellite Tonight is my most successful side project so far, with 5 million users since launch in 2019. It's been entirely a solo project, and I've used it as a proving ground for a bunch of tech that I wanted to learn. It took dozens of APIs and services to put together the experience I wanted: The front page…

One of the most useful lessons I learned from working at Facebook had nothing to do with technology: Doubt the media. Always doubt the…
