up - tool for writing Linux pipes

https://github.com/akavel/up

up is the Ultimate Plumber, a tool for writing Linux pipes in a terminal-based UI interactively, with instant live preview of command results.

The main goal of the Ultimate Plumber is to help interactively and incrementally explore textual data in Linux, by making it easier to quickly build complex pipelines, thanks to a fast feedback loop. This is achieved by boosting any typical Linux text-processing utils such as grep, sort, cut, paste, awk, wc, perl, etc., etc., by providing a quick,interactive, scrollable preview of their results.

Erlang 'process'

https://www.quora.com/What-is-the-difference-between-system-threads-and-process-threads-as-in-Java-threads

Excerpt:

Erlang uses the term "process" because it does not expose a shared-memory multiprogramming model. Calling them "threads" would imply that they have shared memory.

Mongo - exporting and importing a single database

On Source Machine
-------------------------
mongo
> show dbs
> exit

mongodump -d abc_xyz_development

(Above command will create a dump/abc_xyz_development folder and put all the files inside it. This folder will need to be zipped and sent to whoever wants to import the database)

On Target Machine
-------------------------

Drop existing database
mongo

> show dbs

> use abc_xyz_development;
> db.dropDatabase();
> exit

Restore from Dump folder:
Command:
  mongorestore -d
E.g.
  mongorestore -d abc_xyz_development ~/abc_xyz_development
