Simple Github -> Discord webhook

Step 1 - Make a Discord Webhook

  1. Find the Discord channel in which you would like to send commits and other updates

  2. In the settings for that channel, find the Webhooks option and create a new webhook. Note: Do NOT give this URL out to the public. Anyone or service can post messages to this channel, without even needing to be in the server. Keep it safe! WebhookDiscord

Step 2 - Set up the webhook on Github

  1. Navigate to your repository on Github, and open the Settings Settings

What to do when your ubuntu distro is End-of-Life

Let's say you're using Ubuntu 13.04 (Raring Ringtail, released in April 2013) and it just went End-of-Life on you, because it's supported for only 6 months, and the deprecated packages are taken down after 12 months.

You'll probably figure this out the hard way. When you run sudo apt-get update, it will eventually report these errors:

Ign http://archive.ubuntu.com raring-updates/universe Sources/DiffIndex
Err http://security.ubuntu.com raring-security/main Sources
  404  Not Found [IP: 91.189.91.15 80]
Err http://security.ubuntu.com raring-security/universe Sources
  404  Not Found [IP: 91.189.91.15 80]
