This is how I git
Every now and then I get questions on how to work with git in a smooth way when developing, bug-fixing or extending curl - or how I do it. After all, I work on open source full time which means I have very frequent interactions with git (and GitHub). Simply put, I work with git … Continue reading This is how I git →

It would not only get Python into the browser, but with the fact that both iOS [https://developer.apple.com/documentation/javascriptcore] and Android [https://developer.android.com/guide/webapps]…

Important women in CS who aren't Grace Hopper (2018)
I’m tired of hearing about Grace Hopper, Margaret Hamilton, and Ada Lovelace. Can’t we think of someone else for once? I went ahead and compiled a bunch of really important women according to some fairly arbitrary rules: There’s a specific thing you can point to and say “That. That’s their contribution.” This leaves…

Parallel Seam Carving
Seam carving is a technique for content-aware resizing, which changes the size of an image while attempting to preserve the interesting content of the image. The basic idea behind the technique is to remove low-energy seams: paths of pixels that are similar to their surroundings. A removed seam can be either vertical…

Guide to Making 3D Maps with Satellite Imagery in R
E ver since I released rayshader to the public, there’s been one question that comes up time and time again: “How do I use rayshader to overlay satellite imagery onto a 3D surface?” And I can see why: 3D maps with real satellite images are super cool, and there are few detailed tutorials out there on how it’s done in…

Letsencrypt, the Good, the Bad and the Ugly
Letsencrypt is a pretty neat concept: free secure certificates for web servers, in order to increase the adoption of HTTPS across the web. The basic idea is that certificates should be free, that the barrier to install them should be as low as possible and that updating certificates should be automated. It protects…

Google Apple Contact Tracing (GACT): a wolf in sheep’s clothes?
I wrote a critical piece about the Google Apple Contact Tracing (GACT) platform a few days ago . This resulted in quite some discussion, which brought some more arguments to the fore, that I would like to address and clarify here. Here I focus on my area of expertise: privacy. My colleague Tamar Sharon wrote an…

If someone asks if you have any questions, ask a question

ARM and Lock-Free Programming
I was inspired by the release of Apple’s M1 ARM processor to tweet about the perils of lock-free programming which led to some robust discussion. The discussion went pretty well given the inanity o…

Appearances vs. Experiences: What Makes Us Happy
In the search for happiness, we often confuse how something looks with how it’s likely to make us feel. This is especially true when it comes to our homes. If we want to maximize happiness, we need to prioritize experiences over appearances.

Towards a Rust Foundation
In my #rust2020 blog post , I mentioned rather off-handedly that I think the time has come for us to talk about forming a Rust foundation. I wanted to come back to this topic and talk in more detail about what I think a Rust foundation might look like. And, since I don’t claim to have the final answer to that question…

My Engineering Axioms
A few months back I gave a talk in which I shared a list of my personal engineering axioms – things that, over the years, I've come to think of as generally true and useful to have in mind when writing code, building things, and working with others.

Ruby Concurrency Final Report
Ruby's native I/O methods traditionally blocked the calling fiber, leaving event-loop libraries to provide replacement wrappers. This Ruby Concurrency Progress Report presents a lightweight per-thread Fiber Scheduler which lets those native operations cooperate with an event loop. It explains the implementation and…
