Core Coding Standard

Coding practices are a source of a lot of arguments among programmers. Coding standards, to some degree, help us to put certain questions to bed and resolve stylistic debates. No coding standard makes everyone happy. (And even their existence is sure to make some unhappy.) What follows are the standards we put together on the Core team, which have become the general coding standard for all programming teams on new code development. We’ve tried to balance the need for creating a common, recognizable and readable code base with not unduly burdening the programmer with minor code formatting concerns.

A set of instructions on how to fix the harfbuzz + Infinality issue and restoring good-looking, Infinality-like font rendering.

Disclaimer: Please follow this guide being aware of the fact that I'm not an expert regarding the things outlined below, however I made my best attempt. A few people in IRC confirmed it worked for them and the results looked acceptable.

Attention: After following all the steps run gdk-pixbuf-query-loaders --update-cache as root, this prevents various gdk-related bugs that have been reported in the last few hours. Symptoms are varied, and for Cinnamon the DE fails to start entirely while for XFCE the icon theme seemingly can't be changed anymore etc.

Check the gist's comments for any further tips and instructions, especially if you are running into problems!
