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.

If you need to set up a mailing list, I will suggest two choices:
- http://www.phplist.com/ An open source email campaign manager, with an hosted option The Free account has an unlimited number of contacts, but a 300 message per month limit.
- http://www.mailchimp.com Commercial hosted solution. Very nice site, with a strong appeal. Free Up to 500 contacts, so the first seems better.
One of the best thing of scripting languages like Python is the ability to fast prototype complex things. In the past ten years, if you like to build distributed application you was forced to use huge and heavily languages like Java.

Abbiamo fatto una rapida analisi dell’ Apple iPad in un articolo precedente: vediamo questa volta come l’iPad si inserisce in una possibile strategia globale dell’azienda di Cupertino.
La maggior parte delle osservazioni che faremo sono corroborate da accadimenti storici, il resto sono previsioni di breve termine ma illuminanti.

C'è stata molta eccitazione intorno alla presentazione dell'iPad da parte della Apple.
Il prodotto finale risulta una specie di "iPhone più grosso", con funzionalità simili al Kindle di Amazon, che ovviamente consta circa 200 dollari di meno.
E allora dove sta la novità, la geniale lungimiranza di Steve Jobs?
In realtà l'iPad è un passo avanti nel tentativo di creare un ecosistema che faccia terra bruciata dei concorrenti, come già è successo per l'iPhone ("il solito cellulare touch..."ricordate?): vediamo perché.

Da Acquadro.it, leggiamo questo suggerimento su come trasferire le email da Outlook al vostro Mac:
Nel mio recente passaggio a MacOsX, uno dei problemi che ho dovuto risolvere è stato il trasferimento delle email dal vecchio PC ( Outlook Express su WinXp) a Mail di Apple. Ho installato un mail server sul PC (hMailServer),creato un account e trasferito dal O.E le email via IMAP in windows. Sul Mac ho aggiunto un nuovo account che puntasse al server mail installato e copiato in locale tutti i messaggi.

Every Year, Giovanni consider some "trends" based on his consultant experience. This trends have been gathered in the last six months, and are printed at regular basis. This thoughts are note merely "preference", but are strong opinions based on IT firms products, cleared by buzz-words and soap-opera-like scoop (like "Wired" bad ideas are :).
CMS Market is still facing PHP simplicity versus huge software house products.
Druapl & Wordpress are good. Drupal is an ace if you are very dynamic needs. For instance, multi-language sites, forums, polls and so on are a snap to install. But if usability is a concern, choose wordpress. joomla/Mambo are not so good in my own opinion, but I’d like to her a comment from you.

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.
