A simple SimpleDB use case

I’m happy to say that I had the chance to use Amazon AWS for a project of my customer Deltatre.

The news is particularly good because it offers a real argument in the “use or don’t use it” debate, and offers practical innovation to the company.

Technically, we decided to go on with SimpleDB during the development of deltatrePULSE (or simply Pulse) product: the idea of CTO Carlo De Marchis is to create a new distributed system that will open more the Deltatre web/sport platforms. Continue reading A simple SimpleDB use case

Apache, SSL/TSL and SNI status

I’m trying to host my handful of web sites on Amazon, but in EC2 machines there’s support for only one IP (private and public) and, as you know, SSL/TLS encryption let you have only one domain name per IP address: this is a heavy limit (with a reason), but it’s unacceptable for some reasons (public IP addresses scarcity, cost and management overhead).

Besides other solutions (multi-domain certs for example), I would like to go for the most reasonable way: virtual hosted SSL/TLS web sites, exactly the same way we all use today for non-encrypted web sites. I use Apache and for it there are a couple of solutions in the works that implement SNI or Server Name Indication: an extension to TLS protocol that “… permits the client to request the domain name, before the certificate is committed to by the server“. The support in browsers can be also a problem, but every recent browser supports it (with the exception of IE 6 and 7, apart from Vista); try your browser here.

Google Chrome Mac Builds

Here you can find the builds of Chromium (the open source project on which Google Chrome is built) for Mac OS X that the fine guys at Google are preparing for us.

Waiting for an official version of Chrome (and for Firefox 3.1), let’s continue the browsers’ war on features and not on the garbling of web standards!

Blogengine.NET Textile Extension

An extension to add Textile support to Blogengine.NET, directly derived from the Markdown extension by Alexander Schuc (who I thank a lot).

Lightweight Microsoft.NET Process Debugging in Production Environments

Everyone is aware of the problem of discovering the causes of a bug when it’s only present in one environment and, if it’s Production, the problem is even bigger, even if you have a solid error logging system in place.

Recently we faced this same situation and we didn’t have any clues to help us, only that the w3wp process was dying and the ASP.NET session remained locked. After some thought, we arrived at the conclusion that there was an infinite loop somewhere, and we had a vague idea of the “zone” of code where this was happening, but we couldn’t reproduce it in any other environment even after several hours of testing.

The Italian iPhone Scandal

Just today, on the announced first day of iPhone 3G on the market, the Italian “competitive spirit” has struck again: it seems that Vodafone and TIM have “agreed” to maintain prices of the iPhone ridiculously high; luckily someone has noticed it and reported it to the antitrust agency, which will monitor now possible violations of the law: TLC. I-phone, Antitrust opens pre-inquiry on Tim and Vodafone after the petition submitted by the Movement of Defense of the citizen (MDC).

Many people are protesting (as can be seen looking on search engines), and in particular the site melamorsicata.it launched the online petition iPhoneAffossato, which should help to disseminate more information to the public.

Despite the cost too high compared to other countries, the iPhone is selling well (at least judging from the numbers of the Vodafone shop, if they are real…) and probably the boycott, suggested by several parties, will not have the necessary effectiveness to lower the rates of the two companies: have we to hope in the Tre offer?

Bilingual Support

From today my blog supports more than a language, English and Italian.

The reason behind this addition is that I felt a bit uncomfortable writing only in English some posts that I would like to be read also in my language, to support the diffusion of technologies and ideas that I think about as important in the country were I live and work.

The preferred language can be choosen selecting it in the top right of the home page. I added the multilingual support to WordPress installing the qTranslate plugin, very well done even if it has some small defects.

So have a good reading!
