Delete Git branch locally and remotely

I stumble across this one every so often. And since I have to look it up every time, I may as well document it. Today's post is small and easy.

To delete a Git branch after the completion of a feature or bug fix, you can use the following commands. Cause the CLI rules, right, RIGHT? Anyway, back to the task at hand.

## Delete a remote branch
$ git push origin --delete <branch> # Git version 1.7.0 or newer 
$ git push origin :<branch> # Git versions older than 1.7.0

Result window is too large, from + size must be less than or equal to: [10000] but was [1000000]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level parameter

I suppose the proper fix would be to modify the code to use the scroll API, but for a quick fix, you can use the following:

curl -XPUT http://localhost:9200/doraana/_settings -d '{ "index" : { "max_result_window" : 1000000 } }'

Use kibana

With Elastic server: http://localhost:9200/doraana, with index: doraana

Introduction

Mina is a gem which is very simliar to Capistrano but much FASTER!
See https://github.com/nadarei/mina for the gem

Cross-platform means of getting user's home directory in Ruby

On unix platforms (linux, OS X, etc), ENV["HOME"], File.expandpath('~') or Dir.home all rely on the HOME environment variable being set. But sometimes you'll find that the environment variable isn't set--this is common if you're running from a startup script, or from some batch schedulers. If you're in this situation, you can still get your correct home directory via the following:

require 'etc'
Etc.getpwuid.dir

Having said that, since this question is asking for a "cross-platform" method it must be noted that this won't work on Windows (Etc.getpwuid will return nil there.) On Windows, ENV["HOME"] and the methods mentioned above that rely on it will work, despite the HOME variable not being commonly set on Windows--at startup, Ruby will fill in ENV["HOME"] based on the windows HOMEPATH and HOMEDRIVE environment variables. If the windows HOMEDRIVE and HOMEPATH environment variables aren't set then this won't

iTerm2 - color 'ls' and other outputs for MacOS

That's right. For OS X and BSD's ls, the flag is -G. Many people customize the behavior of ls by replacing it with an alias that adds extra options. I have the following in my .bashrc, for example:

alias ls='LSCOLORS=gxfxcxdxbxexexabagacad /bin/ls -bFHGLOPW'

Besides enabling colors in general, this sets the LSCOLORS variable in order to change which ones ls uses.
