Created this by pasting together a few screenshots from a NetBeans profiler session – of a Spring + Hibernate web-app running within JBoss. Quite interesting to see how the business logic is …
Last week was the release of Oracle’s GraalVM. As stated on the website: GraalVM is a universal virtual machine for running applications written in JavaScript, Python 3, Ruby, R, JVM-based languages like Java, Scala, Kotlin, and LLVM-based languages such as C and C++. GraalVM removes the isolation between programming…
Jumping on the recent trend, I picked up a copy of A Philosophy of Software Design based on Cindy’s recommendation. It’s a fairly concise read at 160 pages, and I skimmed through it over the last few days, writing up some notes along the way.
Much has been written about fuzzing compilers already, but there is not a lot that I could find about fuzzing compilers using more modern ...
Note: This post was originally titled “Stop writing lambda expressions in Python” but I’ve changed the title after deciding that it was a little...
IOTA is a cryptocurrency targeting the internet of things. It purports to be scalable, decentralized, and feeless. Unfortunately it is none of those things.
A few weeks ago my most popular repository on GitHub was crowbar , a Rust crate that I’m particularly proud of. It wasn’t necessarily good , but it did something interesting. It has 168 stars.

“Common what?” is a common reply I get when I mention Common Lisp. Perhaps rightly so, since Common Lisp is not all that common these days. Developed in the sixties, it is one of the ol…
A short essay about the evolution of programming languages.
Quote: if you DO want to get performance from changing mallocs, make sure to test them with your own app Another Quote: in our humble opinion, overall winner...
I’ve been digging into .NET Internals for a while now, but never really looked closely at how the ‘Just-in-Time’ (JIT) compiler works. In my mind, the interaction between the .NET Runtime and the JIT has always looked like this:
Having just written rather a sad piece on my company’s blog, I thought I’d cheer myself up a bit — and explain a few things that have been hugely …
Have you ever watched a school of fish, a flock of birds, or even a crowd of people and watched how they move?
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...
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 ...

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...
