http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_important_configuration_changes.html#_minimum_master_nodes

The minimum_master_nodes setting is extremely important to the stability of your cluster. This setting helps prevent split brains, the existence of two masters in a single cluster.

When you have a split brain, your cluster is at danger of losing data. Because the master is considered the supreme ruler of the cluster, it decides when new indices can be created, how shards are moved, and so forth. If you have two masters, data integrity becomes perilous, since you have two nodes

# https://github.com/composer/composer/issues/2798
# Failed to enable crypto
grafhax commented on Dec 3, 2014

I've encountered this problem when setting up new dev environments on my mac. To solve the issue i've had to make sure the php-curl library was compiled with php and updated. I generally do this using MacPorts to manage/compile the libs.

# update the ports tree (software list)
$ sudo port -v selfupdate
# install php (shortcut for compiling php with our required libs)
$ sudo port install php56

GitHub Javascript Strategy

Unless otherwise necessary (such as mobile development), the GitHub javascript codebase is based off jQuery. You can safely assume it will be included on every page.

File naming

• All jquery plugins should be prefixed with jquery, such as jquery.facebox
• All github-specific jquery plugins should be prefixed with jquery.github. Like jquery.github.repo_list.js
• All page-specific files (that only run on ONE page) should be prefixed with page. page.billing.js
