Fare il cloud da zero: cloudStorm
Aug 10th
A Gioorgi.com ci siamo già occupati di argomenti prettamente sistemistici come la virtualizzazione di ambienti Unix. Visto il successo del Cloud Computing, abbiamo pensato di tornare sull’argomento.
In questo articolo mostrerò come creare insieme di macchine configurate in modo omogeno, con il minor effort sistemistico possibile. Si tratta di un primo esercizio molto semplice.

MeeGo avrà più successo del Symbian?
Mar 2nd
This entry is part 4 of 4 in the series IT Economy
C’è stato poco tempo fa il Mobile World Congress di Barcellona. Vista la vicinanza con il rilascio di iPad, e l’aggressività di Apple (che sositene essere un forte competitor Mobile), vale la pena fare qualche rilfessione.
Tra le tante presentazioni fatte, mertiano una citazione Windows Mobile 7 e MeeGo.
Con Windows Mobile Microsoft punta fare concorrenza diretta ad Apple, ma dovremo aspettare il Natale 2010 per vedere cosa succederà. Di certo il nuovo sistema operativo di Redmond è più esigente in fatto di risorse e quindi speriamo le usi bene….

Managing Cluster of Unix Machines Part3: Speed setup
Dec 7th
Setting up a bunch of Linux machines is easier now, thank to company like http://turnkeylinux.org/
At Gioorgi.com we have the need to setup a tiny box with PHP Mysql and a bunch of unix utilities, to automate common tasks.
We took one of the TurnKey iso, and then we customized it via the apt-* utilities. Let’s see the steps
(more…)Mastering clusters of Unix machines part2: the right tools
Oct 12th
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.
OpenPKG is a very clever stuff, because enable you to install multiple copies of the same software with minimal effort.
CFEngine is “an automated suite of programs for configuring and maintaining Unix-like computers.”
One of the strong ideas, is the cfengine ability to “self-repair” configuration, which More >
Mastering clusters of Unix machines part1: the right VM
Oct 5th
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 More >
forums.humdi.net • View topic – can vnstat be used to avoid overage automatically???
Sep 12th
vnStat doesnt currently have integrated a feature for executed commands or getting alerts sent when some predefined limit is reached but is seems Ill need to add that to the TODO list since you arent the only one requesting this.Even with the current version, such feature isnt too hard to make using a script. See the example that Ive attached to this post. Gunzip it gunzip trafficalert.sh.gz, make it executable chmod 755 trafficalert.sh and edit is before putting it to for example /etc/cron.hourly if a hourly resolution is enough for your use. The limit variable in the script is in More >
WebDAV versus Sshfs
Aug 3rd
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.
WebDAV
Samba and NFS are for sure more fast and reliable, but webdav offers some nice feature:
- Webdav is easy to set up on apache web server
- Webdav uses simple http protocol extension, so you can use it also behind web proxy
- You can use HTTPS protocol to get SSL encryption
- Apple uses it for its iDisk solution, so you get the More >
The best netbook-friendly Linux distros
Jun 12th
Hands-on We loved the Xandros based OS the Asus put on the original Eee PC for its simplicity and direct access to applications. Likewise Acer’s version of Linpus, installed on the Linux versions of its Aspire One netbook. For 90 per cent of the tasks anyone’s likely to perform on a netbook, they’re spot on and allow the machines to boot up in under 20 seconds.

A very good hosting provider
Mar 3rd
After my past experience with bad hosting provider, I am happy to say I have find a very good hosting service. If you need VPS hosting, Rimuhosting is a very good choice.
After about two years with Rimuhosting, I can summarize their feature here:
- They have a very good entry-price for a virtual hosting
- System aministrator has a very prompt response: on every issue I get support in 24 hours, also on Sunday
- Rimuhosting uses a Xen virtualization mechanism which is very effective. I have tried other virtualized solution, which are worst.
- Java hosting works well, without problems.
- The default Bandwith is very huge (30GB). There is More >
