In a nutshell, xargs is an alternative to fully expanded shell for loops. Given the right options, xargs can be made to exhibit for-loop-like behavior. But out of the box, it is a way to pipe a bunch of arguments to a single command in one fell swoop.
In 聽A small primer on xargs聽you will find a deep explanation on xargs usage. The article teach me a bunch of tricks I am not aware of (and I know Unix from ‘93….yes, 1993…).This can save a great deal of compute time if you are piping a long list of arguments to a command rather than iterating over them one at a time.

In my code ramblings during the developement of Code Zauker, I ended up studing a bit NoSql聽 database.
Code zauker started using Redis, because Redis is a very bold memory-based no-sql db. Redis also support complex data type like sorted set, lists and so on, which was very userful. Anyway I needed a very fast way of doing statistics on data collected by code zauker, for inspecting data and finding out new feature I’d like to add to it. Worst, my current pocket pose a hard limit on a redis instance in terms of available RAM. So I started thinking a lot about a redis drop-in replacement for Code Zauker.

When Google Code was shut down, I have the lucky to read this article on how it worked. The article give you a bunch of Google-Go code. Because Go-language is too small and unusual for my brain, I took the idea and reimplemented it using Ruby and聽Redis.
And because my nickname is Daitangio, I decided to call the project like the Daitarn3 antagoinst: the Code Zauker![1]
