If you are seeing Mongo soft rlimits warnings in your logs, or a WARNING: soft rlimits too low. Number of files is 256, should be at least 1000 when you login to mongo shell via mongo from the commandline, or any mysterious/unexplained mongo connection errors... follow this how-to exactly and it will resolve the issue for you.
(Source of this how to found at basho/basho_docs#1402)
First file:
sudo vi /Library/LaunchDaemons/limit.maxfiles.plist
...containing:
WARNING! Do not install anything from update sites before installing Eclim! This is because Eclim determines available project natures (android, scala, etc) by trying to discover them at install time. If they are installed on a per-user basis, it won't find them. If you're installing Eclim for use with an existing Eclipse install
You're also better off not to install any plugins via your package manager. Eclim will give you the option to install plugins associated with each project nature from its install wizard.
Install Eclipse Luna. On Arch Linux, it's available in extra.
pacman -Sy eclipse

| * This is an attempt to find a minimal set of type classes that describe the map-reduce programming model | |
| * (the underlying model of Google map/reduce, Hadoop, Spark and others) | |
| * The idea is to have: | |
| * 1) lawful types that fully constrain correctness | |
| * 2) a minimal set of laws (i.e. we can't remove any laws, | |
| * 3) able to fully express existing map/reduce in terms of these types | |

| # Python script to find the largest files in a git repository. | |
| # The general method is based on the script in this blog post: | |

| # The above script worked for me, but was very slow on my 11GB repository. This version has a bunch | |
| # of changes to speed things up to a more reasonable time. It takes less than a minute on repos with 250K objects. | |
