But also check that it's not overridden in Settings -> Configure Shortcuts

Noto Mono + Color Emoji Font Configuration for KDE/Konsole

Konsole/KDE apps use QT rather than the GTK emoji setup. So standard Ubuntu setup doesn't seem to work.

If you want the Snake emoji in your Python venv Powerline then see below!

To test we create a file much larger than we’d read in with a typical AoC question - let’s mimic day 11 of 2021 (also valid for day 09 too) available here.

shuf -i 1000000000-9999999999 -n 10000000 -o big_test.txt

With a file this big, my original solution runs out of memory due to garbage collection issues. The problem here was misunderstanding eager comprehensions - the nested map should be part of the list comprehension itself not applied afterwards!

A good link about comprehensions in Scheme for reference.

There is no WSL or Multipass on Guix, but we can get the same thing with QEmu (and a lot more). But it’s a bit trickier to get started!

Guix packages required:

• qemu (possibly can get away with minimal package)
• cloud-utils (for cloud-localds)
• cdrkit-libre (for genisoimage, used by cloud-localds)

Create the following user data file - there may be more in this than you need.

Can be used from qemu Ubuntu instance (see other gist).

Clone and build this on the host:
https://github.com/ponty/framebuffer-vncserver

Run it *as root*:
sudo ./framebuffer-vncserver -t /dev/input/by-path/platform-i8042-serio-1-event-mouse -k /dev/input/by-path/platform-i8042-serio-0-event-kbd

You can use the direct /dev/input/eventX as well if you want.

Interfacing C with Emacs Lisp

Introduction

This document provides a step-by-step guide for interfacing C with Emacs Lisp, designed for readers familiar with basic Ubuntu, C, and Emacs usage.

Installing Necessary Tools

GNU Scientific Library (GSL)

• Install GSL: sudo apt-get install libgsl-dev

Emacs

(I compiled Emacs 29.1 from source, but this should also work)

• Install Emacs: sudo apt-get install emacs
