The majority of performance improvements in modern processors are due to increased core count rather than increased instruction execution frequency. To maximise hardware utilization, applications need to use multiple processes and threads. Servers that process discrete requests are a good candidate for both…
It's been five great years, but now it is time for me to move on and try something else. During these five years I've met and interacted with a large number of awesome people at Mozilla, lots of new friends! I got the chance to work from home and yet work with a global team … Continue reading I’m leaving Mozilla →
The Pivot is celebrated in startup land. Huge successes like Twitter and Slack are all the results of pivots. So surely pivoting is a good thing, right? Well, I am not so sure. And I certainly don’t want entrepreneurs to think that pivoting is the right thing to do when their original idea fails. It […]
The sound made by the Krakatoa volcanic eruption in 1883 was so loud it ruptured eardrums of people 40 miles away, travelled around the world four times, and wa
What’s going on in the brains of people who meditate? Anecdotal evidence suggests that meditation does something to people’s minds and bodies…quiets and calms t
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.
How I wrote GoAWK, how I tested it, and how I measured and improved its performance.
A short essay about the evolution of programming languages.
tl;dr: Rebuilding a target because its mtime is older than the mtimes of its dependencies, like `make` does, is very error prone. redo does...
These are some of the most amazing generated images I’ve ever seen. Introducing BigGAN, a neural network that generates high-resolution, sometimes photorealistic, imitations of photos it’s seen. None of the images below are real - they’re all generated by BigGAN.
In this article we’ll go on a journey from 4-bit microcontrollers to room-sized mainframes and learn how porting C to each of them helped people separate the essence of the language from the environment of its birth. I’ve found technical manuals and videos for this article to help bring each computer to life.
As of last nightly (20181115100051), Firefox now supports Wayland on Linux, thanks to the work from Martin Stransky and Jan Horak, mostly.
A handy rule of thumb for creating a confidence interval for the probability of an event you haven't seen happen yet.
Type inference is a major feature of several programming languages, most notably languages from the ML family like Haskell. In this post I want to provide a brief overview of type inference, along with a simple Python implementation for a toy ML-like language.
Last week I wrote a couple of different pieces on passwords, firstly about why we're going to be stuck with them for a long time yet [https://www.troyhunt.com/heres-why-insert-thing-here-is-not-a-password-killer/] and then secondly, about how we all bear some
Since February 2016, I have been participating in DIYRobocars meetups here in the SF Bay Area, wherein a bunch of amateur roboticists compete in autonomous time trials with RC cars. I had been doing very well in the competition with essentially just a glorified line-following robot, but have lately upgraded to a full…
One of the main use cases for the Zig Programming Language is operating system development and embedded development. So, what better way to make sure the language is suitable than to work on a project in this field?
An Unexpected Consequence of a Bad Header
My dad started teaching me Basic when I was about 7 years old, and since about that age I knew that I wanted to build software for a living. It was obviously a fun and useful thing to do, and something that I could do well. But there is a big — and I mean Grand Canyon-scale BIG — difference between “programming” and…
Tensorflow 2.0 will be a major milestone for the most popular machine learning framework: lots of changes are coming, and all with the aim of making ML accessible to everyone. These changes, however, require for the old users to completely re-learn how to use the framework: this article describes all the (known)…
In this article we will look at the various ways an object can be copied in Javascript. We will take a look at both shallow and deep copying. While shallow copying is rather straightforward, deep copying is more tricky. Currently, there is a HTML5 specification for a deep copy algorithm but it is not publically…
Modern processors execute instructions in parallel in many different ways: multi-core parallelism is just one of them. In particular, processor cores can have several outstanding memory access requests "in flight". This is often described as "memory-level parallelism". You can measure the level of memory-level…
I know a change is going to come If you’re an early employee at a startup, one day you will wake up to find that what you worked on 24/7 for the last year is no longer the most important thing R…
