After working with unix for years, we noticed it is difficult to get a very uniform approach to unix management.

Often different Linux distributions share very little, configuration is different every time. Worst, some good unix tools (like cron, syslog, etc) can be used in a distributed environment, but are very difficult to configure, very user unfriendly and so on.

One day, we have the need to create a fast cluster of linux machine, specialized and easy to segragate in different networks (for better security). We need web servers, integration servers (running java hudson), huge developer machines (running for instance eclispe) and so on.

It was not easy to find a good environment. This research lead us also to consider a very huge set of different and complex management software. In this series of article, we will show what we discovered.

Or final goal is to have a way to define a set of linux virutal machines, connect them and manage all using open source software. We also want tools easy to understand. We do not want super-optimized stuff, we have the “just it works well” approach.

We thinked about these types of virtual machine: super light LAMP servers, medim sized java tomcat servers (or udson servers), big database machines and super big development machines.

News Corporation's James Murdoch says that a 'dominant' BBC threatens independent journalism in the UK and that free news on the web provided by the BBC made it 'incredibly difficult' for private news organizations to ask people to pay for their news.

via Slashdot | James Murdoch Criticizes BBC For Providing "Free News".

It is not the first time Murdoch is trying to fool us. Murdoch new war is trying to persuade people news on the web must be paid. It is difficult to fight this war, nowedays: it is like to try to get paid for email delivery, or for accessing to things like twitter or facebook.

At Gioorgi.com we evaluted a internet file system common gateway for connecting network resources. We compared two solutions: a webdav file system and an ssh-fs file system. The solution should be viable via MacOSX and Linux, but also Windows support will be a plus.

This magic CSS code is able to change the orientation of the printed page:

@page port {size: portrait;}
@page land {size: landscape;}
.portrait {page: port;}
.landscape {page: land;}

For more information, take a look to the CSS Print Profile specification

I thinked it was not possible to define printing orientation via a simple CSS! A very nice discovery indeed…

Several years ago I had the need of keep in sync three computers.  After some questions on a java mailing list, a very smart guy suggested me Unison.

Unison is a file-synchronization tool for Unix and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.

Unison shares a number of features with tools such as configuration management packages (CVS, PRCS, Subversion, BitKeeper, etc.), distributed filesystems (Coda, etc.), uni-directional mirroring utilities (rsync, etc.), and other synchronizers (Intellisync, Reconcile, etc). However, there are several points where it differs:[…]

At Gioorgi.com we have used plenty of web frameworks.

Giovanni Giorgi used Seaside,  a lot of PHP frameworks, Java Struts, RubyOnRails, and Python Django.

We have started to look for Web2Py, a compact,  easy to learn  python web framework.

From the most notable feature, it runs also on Google App Engine. Written by an Italian University professor for teaching web development, spots a very clean design, and a robust security infrastructure. We  suggest it because installation (and upgrading) is a snap.

Let’s take a look to it…
