Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.
For the sake of this example, let’s pretend the subfolder containing your site is named dist.
Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).
Suppose you have a number of nodes on a network that spin up cron jobs to perform various tasks. However, you need the nodes to cooperate to ensure that multiple nodes don't spin up the same task. You can easily implement this functionality on top of RethinkDB as follows:
// A single node atomically pushes jobs onto an array in the database
r.table('admin').get('jobs').update({ job_list: r.row('job_list').append(JOB_DESCRIPTION)) })
| r.table("test").filter( function(doc) { | |
| return doc("adresses").contains(function(adress) { | |
| return adress("city").eq("Paris") | |
| }) | |
| }) | |
