HFS+ Bit Rot
HFS+ is a terribly old filesystem with serious flaws. I sincerely hope that Apple comes with an update of the filesystem for WWDC 2015. After all they have been working on Swift for the past 4 years and we have just learned about it last week. HFS+ is seriously old HFS+ was released in 1998, in the era of Mac OS…

Learn Wayland by writing a GUI from scratch
Wayland is all the rage those days. Distributions left and right switch to it, many readers of my previous article on writing a X11 GUI from scratch in x86_64 assembly asked for a follow-up article about Wayland, and I now run Wayland on my desktop.

Best Practices for Time Travelers (2003)
When John Titor first showed up on IRC chat in October of 2000, he was enjoying a neat kind of double billing - as his 38-year-old self sat downstairs in the kitchen, typing away, a two-year-old version of himself lay sound asleep upstairs in bed.

We Looked for Work as a Software Development Team
Part of this story is a common one. Established company in an industry undergoing major disruption hires developers to innovate back to viability. Management lacks clear vision of what that means and so chops and changes ( not pivots, that’s something else) technology strategy several times. After two years of hard…

My tutorial and take on C++20 coroutines
Over the last 25 years, I’ve written a lot of event-driven code in C++. A typical example of event-driven code is registering a callback that gets invoked every time a socket has data to be read.
