Do you like Arduino?
Do you like dynamic programming languages like ruby?
Well, the RAD is your Ruby Arduino Development!
We just find out that link on hacker news, which comments worth a read.

Because of the success of my article on java closure, I have decided to write another article on functional programming.
In the last year functional programming is waving back to us, for a lot of reason. Let’s summarize the facts:
Functional programming is based on the core concept of pure function. The main advantages of functional programming is the lack of side-effects, at least at the syntax-level of the language.

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.

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.
Integrate lambdaj in your software architect toolkit (italian link)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.

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.

Cappuccino è un progetto interessante, anche se molto particolare.
Cappuccino is an open source framework that makes it easy to build desktop-caliber applications that run in a web browser. Cappuccino is built on top of standard web technologies like JavaScript, and it implements most of the familiar APIs from GNUstep and Apple's Cocoa frameworks.
With Cappuccino, you don't need to know HTML. You'll never write a line of CSS. You don't ever have interact with DOM. We only ask developers to learn one technology, Objective-J, and one set of APIs. Plus, these technologies are implementations of well known and well understood existing ones. Developers can leverage decades of collective experience to really accelerate the pace of building rich web applications.
Tra i bonus di Cappuccino c'è la possibilità di programmarlo come se si stesse programmando in Objective-C ed in particolare in Cocoa. Può rappresentare un ottimo investimento se avete un background in XCode. L'interfaccia e le librerie constano in circa 10MB di codice compresso: non esattamente una passeggiata.Una delle applicazioni più complicate è http://280slides.com/ che però a tempi di caricamento abbastanza alti.

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.
On Python there is a nice library called Pyro, which used with success:

After reading an interesting article on Erlang and Java interoperability, I have decided to dedicate my spare time to Erlang.
O’Reilly has just published a wonderful book on Erlang, so I decided to dive into it.

The revamp of Jython 2.5, the python interpreter written in Java, is a very good news, because give us the chance to think of a new way of coding. Looking at Google trends, JRuby and Jython are emerging as key pieces of a new puzzle.

The trends of this october are about some upcoming products. A clear analisys of QuarkXPress failure is sketched in roughlydrafted site. I do not think the same consideration can be applied to Vista.
As Joel said, M$ can throw away much money before only starting to see its market reduced.
