Change git init's default branch name

Change the name of the default branch created by git init

Suppose you want the default branch name created by git init (or tools that shell out to it, like cargo new) to be something other than master. In this example, I'll call it develop.

  1. Add the following to your .gitconfig:

    [init]
        templateDir = ~/.config/git/template/

Enhance Rails Intellisense in Solargraph
# The following comments fill some of the gaps in Solargraph's understanding of
# Rails apps. Since they're all in YARD, they get mapped in Solargraph but
# ignored at runtime.
#
# You can put this file anywhere in the project, as long as it gets included in
# the workspace maps. It's recommended that you keep it in a standalone file
# instead of pasting it into an existing one.

How to stop adverts appearing on your Samsung TV

I'm getting adverts in my TV's UI, help!

Samsung's otherwise excellent 2016 range of UHD TVs received an update that added advertisements to the UI. This has been complained about at great length on Samsung's forums and repeatedly, Samsung have refused to add an option to remove them.

The ads interrupt the clean UI of the TV and are invasive. Here's an example of how they look:

one two

This guide was originally posted on Samsung's TV forums but unfortunately, that site is a super-slow and barely accessible unusable mess.

cons = fn (a, b) -> fn x -> x.(a, b) end end
car = fn (p) -> p.(fn (q, _) -> q end) end
cdr = fn (p) -> p.(fn (_, q) -> q end) end
each = fn (list, func) ->
iter = fn (list, func, next) ->
(fn (a, nil) -> func.(a)
(a, b) -> func.(a); next.(b, func, next)
end).(car.(list), cdr.(list))
end
iter.(list, func, iter)
