A couple of weeks ago, I started to work with Emacs, and I grow fonder of it every day. During a very short time period, it has become my go-to editor for nearly everything I do on my computer, including (but not limited to) planning my Todos (in org-mode, to be precise), setting up my agenda (org-mode again), taking…
I tried to boot an iOS 12 kernelcache in QEMU: I managed to get as far as IOKit startup before receiving a kernel panic. I learned a lot about how iOS boots up with this project.
Context A few years after I created the Elastic Binary Trees (ebtree) , I started to get some feedback from users who needed to use the...
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...
Learn the historical reason OpenCV stores color images in BGR order instead of RGB, from early camera formats to compatibility decisions.
This summer, I am again working on Rust full-time, and again I will work (amongst other things) on a “memory model” for Rust/MIR. However, before I can talk about the ideas I have for this ...
PostgreSQL trigger performance. Should we use tiggers at all? Find out how triggers perform in performance tests.
Provide a low-overhead data collection framework for troubleshooting Java applications and the HotSpot JVM.

Electronic mail is one of “killer apps” of networked computing. The ability to quickly send and receive messages without having to be online at the same time created a new form of human communication. By now billions of people have used email.
I am a fond Clojure user, and love to use it for both server-side projects and small command-line tools. I love its expressivity and concision, and I like th...
This is part one of a two-part article. Part two is here. A while back somebody told me to check out MiniZinc. Eventually I did and really enjoyed it, so figured I’d write about it here. This is actually going to be a two part article. Right now we’re talking about what it is and how it works, and in the next post…
IT blog about developing and managing enterprise-level software solutions for blockchain, fintech, transportation & logistics, security, edtech, and advertising industries.
Describing three strategies of implementing type classes, aiming to clarify their behavior
How to solve linear systems that have many solutions, or those that have no solutions at all? That's the theme for a thick math textbook, of course, but from...
Jupyter presents a unique programming style where the programmer can change her code while it's running, reducing the cost of mistakes and improving the interactivity of the programming process. I discuss the benefits and limitations of this approach along with the related work.
This is the 6th post in the Learning Clojure focus series. In general, one learns by comparing to what one already knows: I’m learning Clojure in that way. Coming from a Java background, I naturally want to use streaming features. So, what would be the Clojure counterparts of Java’s functions filter(), map(), etc.?
In this tutorial, you are going to learn the basics of Vue.js. While we learn, we are going to build a Todo app that will help us to put in practice what we learn.
Resurrecting an old tradition of this blog, let’s take a simple problem, go over a way too long list of alternative solutions, and evaluate their merits. Our simple problem is this: we want t…
Map any 3D point on or above a triangle-subdivided sphere to a triangle index in constant time, without recursion, table lookups or complicated branching logic.
In this brief post I want to discuss a fairly unusual feature of Haskell - functions that can be parameterized by their return type.
Whether or not you believe that the iPad is the future of computing, it does bring a ton of interesting new features and capabilities to the table, especially with the latest release of the Pro version. This week, let’s take a look at how we as third-party developers can take advantage of some of those capabilities to…
In a few weeks we will release the first public technology preview of EdgeDB—a new open-source object-relational database. This post is a brief introduction and is the first in the series.
