Why systemd is a problem for embedded Linux
I don’t want to post yet another anti-systemd rant, but I think the ubiquity of systemd could eventually create real problems for embedded Linux. I just wish I knew what to do about it.

FreeBSD – a lesson in poor defaults
This page lists some of the changes I make to a vanilla install of FreeBSD for security hardening. Some changes to increase network performance or make things a bit more sane are also included. It only covers basic changes that a sysadmin can make to a running system.

A simplified model of Fil-C
I've seen lots of chatter about Fil-C recently, which pitches itself as a memory safe implementation of C/C++. You can read the gritty details of how this is achieved, but for people coming across it for the first time, I think there is value in showing a simplified version, as once you've understood the simplified…

Curl doesn’t spew binary anymore
One of the least favorite habits of curl during all these years, I've been told, is when users forget to instruct the command line tool where to store the downloaded file and as a direct consequence, curl instead sends a lot of binary "gunk" to the terminal. The end result of that is at best … Continue reading curl…

I wrote a linker everyone can understand
When we wrote our assembler we made many design choices that helped us cut down on the complexity of the assembler itself. One of those decisions was to have the assembler directly output executables. That was a good choice in that it allowed us to quickly test as we were developing: once we implemented an opcode, we…

Intel Virtualization and Apple Silicon
The transition to Apple Silicon brought about many exciting things, but one of the capabilities left behind was access to the world of Intel-based virtual machines. X86_64 just isn't a trivial architecture to emulate, and it may never be feasible to do so on Apple Silicon at a useful speed as the operating systems you…

I Built Linux from Scratch
Linux From Scratch or LFS is a project that provides and maintains a set of instructions of how to build your own Linux system from scratch. I am always curious to understand how things work ‘under the hood’, and since I’m a daily Linux user i decided to take on the challenge to try and complete building Linux From…

Ideas for getting started in the Linux kernel
Getting new people into OSS projects is always a challenge. The Linux kernel is no different and has it’s own set of challenges. This is a follow up and expansion of some of what I talked about at Flock about contributing to the kernel.

X: The First Fully Modular Software Disaster
X-Windows is the Iran-Contra of graphical user interfaces: a tragedy of political compromises, entangled alliances, marketing hype, and just plain greed. X-Windows is to memory as Ronald Reagan was to money. Years of "Voodoo Ergonomics" have resulted in an unprecedented memory deficit of gargantuan proportions…
