The Isolation Trap: Erlang
Erlang's mailbox design is more disciplined than Go's channels: only the owning process can read from a mailbox, and sends are asynchronous. Yet the four failure modes of shared mutable state still show up, just in different shapes.

JVM exceptions are weird: a decompiler perspective
Some time ago, I played around with decompiling Java class files in a more efficient manner than traditional solutions like Vineflower allow. Eventually, I wrote an article on my approach to decompiling control flow, which was a great performance boost for my prototype. At the time, I believed that this method can be…

Bug finding is slow in spite of many eyeballs

A hundred million cars run curl
One of my hobbies is to collect information about where curl is used. The following car brands feature devices, infotainment and/or navigation systems that use curl - in one or more of their models.

Showing GUIs from Shell Scripts
Ever written a quick (shell) script to automate a small task at some point? Then that script grew over the years and perhaps ended up in the hands of way more users than you originally anticipated? If you were lucky enough to experience this, maybe you wondered: Wouldn't it be nice to have a GUI for that script?

Nuitka Progress in 2015 – Python Compiler

You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of.
