My preferred code style is 2-space K&R. This is intended to provide a justification for this style.

Why K&R?

K&R style has the following properties:

1. Provides symmetric size (in terms of screen space consumed) between the opening and closing syntax of a clode block.
2. Forces no empty or meaningless lines, thereby avoiding artificial distance between related things that should be together.
3. Consumes the minimum vertical space while keeping the opening and closing syntax of a block on separate lines from the content.

Seeing this error in the bash shell when launching some apps, such as scite:

** (scite:5298): WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files

Update as per comments below.

It appears adding this library fixes the problem: at-spi2-core

How @extend Works

@akhleung is working on hcatlin/libsass and was wondering how @extend is implemented in the Ruby implementation of Sass. Rather than just tell him, I thought I'd write up a public document about it so anyone who's porting Sass or is just curious about how it works can see.

Note that this explanation is simplified in numerous ways. It's intended to explain the most complex parts of a basic correct @extend transformation, but it leaves out numerous details that will be important if full Sass compatibility

Rust maintainer perfectionism, or, the tragedy of Alacritty

I did not submit this to Hacker News and did not intend that this post would have high circulation but have no real problem with it being there or with it having such. I have more recent comments below. This post is from January 2020 and predates the Modular Font Editor K (MFEK) project.

I have not worked on Rust projects in quite a while, and don't know if I ever will again. I feel many crate maintainers are way too perfectionist, for example, despite all the developer hours that went into this PR, it took the effort within years to be (halfway) merged.

There's always a reason not to merge, isn't there? It would be better done with a new nightly language feature, or the function signature should have a where clause, or the documentation is not perfect. There's always a new nit to pick in the world of Ru

Sass/Less Comparison

In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.

For Less, I'm using the JavaScript version because this is what they suggest on the website. The ruby version may be different.
