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.

In the past week I learned Flask, a very young and promising python framework. I have already learned Django, Cherrypy, Web2Py and TurboGears.
Anyway, if you are planning a medium sized project, I like to suggest you Flask, because of these feature:

On June 20, 2011, Dropbox had a serious security bug. It was possible to login to an account with “a wrong password”. Like to say Dropbox account system was naked, because “a small number of users[…] could have logged into an account without the correct password”!

I Fatti
Pisapia, il candidato di sinistra (e non tanto di centro 
ha vinto a Milano con il 55,1% delle preferenze.
A Napoli, è stata premiata una coalizione vicina a quella uscente ma distinta, e De Magistris con oltre il 65% delle preferenze avrà parecchia liberta di manovra poiché potrà contare su una maggioranza solida, composta da persone fedeli al suo partito.
Pisapia è stato scelto durante le primarie del centro sinistra, ed ha battuto il candidato moderato Boeri.
L’Italia dei Valori, di cui fa parte De Magistris, non ha mai risparmiato a Berlusconi una critica feroce e circostanziata.

Inversion of Control (IoC) is a very good idea.
But as the clever Joel Spolsky noted, sometimes you need to be a super-natural hero to use it:
… I try not to be judgemental (HAHA!), but I think that people who use IoC containers are (A) very smart and (B) lacking in empathy for people who aren't as smart as they are. Everything makes perfect sense to them, so they have trouble understanding that many ordinary programmers will find the concepts confusing. It's the curse of knowledge. The people who understand IoC containers have trouble believing that there are people who don't understand it. …
I have trouble using Spring in at least two projects. On the third, it was a disaster, because a single software-architect-guy keeps passing around the Spring context factory as method parameter, getting beans from it!

Dapper is a single file you can drop in to your project that will extend your IDbConnection interface. [...]
A key feature of Dapper is performance. The following metrics show how long it takes to execute 500 SELECT statements against a DB and map the data returned to objects.
The performance tests are broken in to 3 lists:
- POCO serialization for frameworks that support pulling static typed objects from the DB. Using raw SQL.
- Dynamic serialization for frameworks that support returning dynamic lists of objects.
- Typical framework usage. Often typical framework usage differs from the optimal usage performance wise. Often it will not involve writing SQL.
