As a work colleague asked me about how I setup my "multi-live-system-thumbdrive": As a base I installed https://grml.org/ but I am sure another system using grub2 would also work. This installed grub on my USB thumbdrive with a rather simple main grub.cfg:

## grub2 configuration
source /boot/grub/header.cfg

insmod regexp

for config in /boot/grub/*_default.cfg ; do source "$config" ; done
for config in /boot/grub/*_options.cfg ; do source "$config" ; done

Paste text on VNC terminal that don't allow copy-paste

Prepare script on terminal
Copy data
Run script
Move focus to destination target
Script will 'type' for you

Let's Destroy C

I have a pet project I work on, every now and then. CNoEvil.

The concept is simple enough.

What if, for a moment, we forgot all the rules we know. That we ignore every good idea, and accept all the terrible ones. That nothing is off limits. Can we turn C into a new language? Can we do what Lisp and Forth let the over-eager programmer do, but in C?

Configure systemd-resolved to use a specific DNS nameserver for a given domain

Building a mingw-w64 GCC cross-compiler with nixcrpkgs: instructions for Terry, October 2018

Install Nix, the functional package manager. You'll need Linux (but macOS might work too).
Make sure you have at least 4 GB of free space available for /tmp and a few GB of free space available for /nix.
To get my recipes, run: git clone https://github.com/DavidEGrayson/nixcrpkgs && cd nixcrpkgs && git checkout 4f7b11d That commit is the current tip of the dev/david/2019 branch.
To build a i686-w64-mingw32 C/C++ cross-compiling toolchain and a hello world program, run: nix-build -A win32.hello
To build Qt and its examples, run: nix-build -A win32.qt.examples
To just build the toolchain itself, run: nix-build -A win32.gcc
