Inspired by this excellent web post “Ruby or Python? Well, it depends...”,
I agree with it at 100%:

Ruby or Python? This is the Question! Well it might not be the Question, but it’s a common question for many developers looking to break free from the statically typed language they know and learn a dynamic language. I personally know them both(though I know a bit more Ruby, than Python) and in this article I’ll share my personal opinion on their strengths and weaknesses. You’d probably do good to learn them both, but my arguments here may lead you to pick only one of the languages depending on you preferences.

Nei mesi passati ho avuto l’opportunità di lavorare come software architect per un progetto basato su .NET e C#.

Da molti anni non bazzicavo in ambito Microsoft, e quindi è stata una utile palestra. Ho pensato di scrivere questo piccolo manuale per sviluppatori java con la ventura di dover diventare… C#-enabled.

Node.js is a Javascript application server based on Google V8 Javascript Engine. Node.js has a very good package manager these days, with a bunch of libraries on it. So it is the new buzz.

Utilities like Telnet and remote control programs like Symantec's PC Anywhere let you execute programs on remote systems, but they can be a pain to set up and require that you install client software on the remote systems that you wish to access. PsExec is a light-weight telnet-replacement that lets you execute processes on other systems, complete with full interactivity for console applications, without having to manually install client software. PsExec's most powerful uses include launching interactive command-prompts on remote systems and remote-enabling tools like IpConfig that otherwise do not have the ability to show information about remote systems.

Sometimes, a client-based refresh of the session is the only viable option.

Anyway, we must define this a “bad idea”, because you can end up stuffing even more problems on your architecture…

Now this is something that may or may not be useful to a lot of people, depending on you situation, you may want the user to elect to refresh their Session or not (like banks usually do); but this is for applications that may have a lot of idle time and users are annoyed with their Sessions dying... considering most users don't know what a Session is, but they know that the application stops working correctly.

It uses jQuery and is incredibly simple, just a few lines of code, and no screen flicker or any annoyance to the user at all; ignorance is bliss. First I include the following in the code-behind in any page you need to keep refreshed (works on masterpages as well)[…]

via Automatically refresh your user’s Session behind the scenes using jQuery and Asp.Net.

1. Download this patch for the visual studio 2008 SP1
2. Download the documentation file from this link http://code.jquery.com/jquery-1.4.1-vsdoc.js
3. Take a rest near the Coffe machine and convert there your co-workers

I have used Google in the past 8 years (I know, I am a bit old). Then I was annoyed because of a bad behavior of Google with my AdSense account (shutdown without being able to talk back to someone for explanation).

Mozy, una società che offriva backup con spazio illimitato, ha dovuto fare marcia indietro. Mozy è considerato un esempio di Cloud computing, e fa parte della costellazione di società che fanno capo a EMC2, che ha nel Cloud una dei suoi cavalli di battaglia. Al momento Mozy offre per 6$ 50GB al mese.

My Big Company asked me to develop a small-sized application using C# and WebForms. The Customer was a big Italian Bank, and it asked for that technology: I was chosen because of my Java seniority, but I was zero on .NET knowledge

The “C# 4.0 In a Nutshell” was a real time-saver for my. The 1000-pages book written by Joseph&Ben Albahari will give you a complete look to the C# Technology.

How many times have you read or written the same two or three lines of code that frequently seem to go together, and even though they operate on different objects, feel like the same thing? And how often these repetitions involve some sort of collections iteration or more generically manipulation? These repetitions in the code is something that developers eventually learn to filter out and ignore when reading code, once they figure out where the interesting parts are placed. But even if the developers get used to it, it slows them down. Code like that is clearly written for computers to execute, not for developers to read.

lambdaj is designed to easily manipulate collections. Its features are intended to filter, convert, index and aggregate the items of a collection without explicitly iterate on it.

Integrate lambdaj in your software architect toolkit (italian link)

Old web site requires sometimes to show a big “Loading…” gif in the front of the page. It is not trivial to do it, especially if you have already plenty of jQuery forms developed, with complex form submission, and half the site in an ajax form.

After the success of Closure in Java we like to show you a good example in C# too.

C# has a very strong support for Lambda functions, because it needs to support the LINQ language constructs.

So defining a closure is quite easy. Best, it is possible to define a “delegate” , which is a typed function: the compiler will help you to avoid errors because will match the lambda function against the delegate.

Per sviluppare bene un software, vi sono tante regole da seguire. Se vi danno la responsabilità di una architettura, vi sono però tre piccoli principi che mi hanno salvato più di una volta. Senza pretendere che essi valgano per tutti, ma conscio del fatto che in oltre 15 anni di programmazione ad oggetti mi hanno salvato più di una volta, eccoli qui:
