This document provides information on typical command-line options and environment variables that can affect the performance characteristics of the Java HotSpot Virtual Machine.
CopyFS aims to solve a common problem : given a directory, especially one
full of configuration files, or other files that one can modify, and which
can affect the functionning of a system, or of programs, that may be important
to other users (or to the user himself), how to be sure that a person
modifying the files will do a backup of the working version first ?
This filesystem solves the problem by making the whole process transparent,
automatically keeping versionned copies of all the changes done to file under
its control.
It also allows a user to select an old version of the files, for example to
repair a mistake, and allows him/her to continue edition from this point.
Lsyncd watches a local directory trees event monitor interface (inotify or fsevents). It aggregates and combines events for a few seconds and then spawns one (or more) process(es) to synchronize the changes.
FSArchiver is a system tool that allows you to save the contents of a file-system to a compressed archive file. The file-system can be restored on a partition which has a different size and it can be restored on a different file-system. Unlike tar/dar, FSArchiver also creates the file-system when it extracts the data to partitions. Everything is checksummed in the archive in order to protect the data. If the archive is corrupt, you just loose the current file, not the whole archive.

shapeless is an exploration of generic (aka polytypic) programming in Scala derived from the various talks I've given over the course of 2011 on implementing scrap your boilerplate and higher rank polymorphism in Scala.
Functional dependencies are a near-standard extension to Haskell (present in GHC and elsewhere) which allow constraints on the type parameters of type classes to be expressed and then enforced by the compiler.
mod_spdy is an open-source Apache module that adds support for the SPDY protocol to the Apache HTTPD server. This allows for faster page loading and more efficient bandwidth utilization when loading https URLs in SPDY-enabled browsers.
Voy a organizar algunas pruebas en ambientes nuestros para tener herramientas como para pedir la instalación en producción, ya que siempre son reticentes a "cosas nuevas".
Gracias por la data!
