Scripted Jenkins Plugins install

Jenkins has a very rich catalog of plugins and it's quite easy to install and update them via UI. BTW, when you want to add tons of plugin via UI, it's a fairly long and boring procedure.

Hopefully, mass installation (or update) could be easy using a simple bash script (curl/python required) :

Create a file containing plugins to be installed (or updated), ie iplugins :

This is a little trick I use to spin up the packages instalation on Debian/Ubuntu boxes in Vagrant.

I add a simple function that checks if a directory named something similar to ~/.vagrant.d/cache/apt/opscode-ubuntu-12.04/partial (it may have another path in Windows or MacOS) and create the directory if it doesn't already exist.

def local_cache(basebox_name)
  cache_dir = Vagrant::Environment.new.home_path.join('cache', 'apt', basebox_name)
  partial_dir = cache_dir.join('partial')
  partial_dir.mkdir unless partial_dir.exist?

# Downloading Oracle JVM without browser

Oracle requires you to accept its licence agreement before downloading its JVM.
It's a pain for those of us who do automation, native packages, Jenkins JVM deployment on slave...

I used Firefox and Firebug to sniff network exchanges.

Dark theme for Mac Slack App

These instructions are my personal implementation of the Slack Black Theme repo. In particular, it is an amalgamation of the css styles in this issue: https://github.com/widget-/slack-black-theme/issues/48

Open ssb-interop.js

Its location will be at /Applications/Slack.app/Contents/Resources/app.asar.unpacked/src/static/ssb-interop.js

Add the contents of slack-dark-theme.js
