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.

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.?

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.
