Introduction The Linux kernel in Ubuntu provides a packet filtering system called netfilter , and the traditional interface for manipulating netfilter are the iptables suite of commands. iptables provide a complete firewall solution that is both highly configurable and highly flexible.

Despot77 posted a great looking Conky Lua configuration at Gnome-Look that displays some beautiful rings for the cpu, clock, ram, swap, disk, net and also comes with an easy way to display the weather that doesn't involve you register to any website, work with API keys and so on. Another thing I like about this configuration is that it comes with various color themes and distribution logos: Fedora, Linux Mint and Ubuntu (update: the package also provides Debian and openSUSE configurations). Here is a screenshot of my desktop - setting it up took under one minute so don't get scared about the instructions below, it's actually quite easy: To set it up (obviously, you must install conky first), download the archive from Gnome Look , extract it and: 1. Create a folder called ".conky" in your home directory and copy the Linux Mint / Ubuntu / Fedora image to this folder.
A new screenshotting tool has been added to the Ubuntu Software Center.

What is Enrollix? Enrollix is a free software for GNU/Linux, Windows and OS X useful to manage enrollments of people to associations, communities, groups, classes, teams, magazines and events like meetings, parties, etc. The software allows to collect detailed personal data of members and of their enrollments with a possible fee, to select them according to any kind of filter and to produce a small balance of the revenues, which can be saved in a CSV (comma separated value) file; this file can be opened with a spreadsheet like Calc or Excel. Furthermore, it is possible to prepare different models of certificates (like a receipt or a certificate of membership) within the software and then print them with the data of any member, also with a possible progressive number (like protocol) within it.
