Merge a git repo as a subdir

In one of my previous gists, there are instructions for converting a repo subdir to a separate repo. In this git we'll go in opposite direction. Suppose we have 2 git repositories A and B.

Problem

Merge B repo into A as dir b/.

Solution

# Clone A
git clone https://github.com/korya/A

WAL-E needs to be installed on all machines, masters and slaves.

How to install WAL-E

Only one machine, the master, writes WAL segments via continuous archiving. The configuration for the master postgresql.conf is:

archive_mode = on
archive_command = 'envdir /etc/wal-e.d/env wal-e wal-push %p'
archive_timeout = 60

Get the share counts from various APIs

Share Counts

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.

XMLHttpRequest

  1. Create a new request
  2. Prepare the request
  3. Set the onload callback. The callback can access the response by referencing this.responseText.
  4. Send the request
  var xhr = new XMLHttpRequest();
