ONJava.com: ONJava 2005 Reader Survey Results, Part 1

ONJava.com: ONJava 2005 Reader Survey Results, Part 1: Chi sono gli sviluppatori Java? Il questionario annuale di onjava.com, un sito O’Reilly, mostra risultati interessanti.
Fra le cose notevoli, un predominio assoluto di Eclipse (76%), un ruolo minoritario per NetBeans (22%) e un ruolo di nicchia per gli ambienti commerciali, come JBuilder e IntelliJ.
Per quanto riguarda il piano acquisti, nessuno ha intenzione di comprare qualcosa quest’anno e ricorrere piuttosto all’open source.
“The feedback to this year’s ONJava survey was tremendous. We received 988 responses in just 12 days–well ahead of last year’s response. It’s great to see that so many people are so interested in Java and how we cover it on the site.”

Scott Wiltamuth’s C# blog : Kids Programming Language (KPL)

Scott Wiltamuth’s C# blog : Kids Programming Language (KPL):
Un linguaggio pensato per i bambini? Interessante.
KPL è basato su .net e può creare codice C# o VB dal sorgente KPL.
Le demo dovrebbero essere divertenti e giocabili.
“Today I had a chance to meet with several people who are working on Kids Programming Language (KPL). KPL is a freely downloadable development environment and immersive runtime for helping kids learn to program. If you have kids who are at the ‘learning to program’ age, which seems to get lower and lower every year, check out this tool. The demo was very cool! The KPL overview has a quick description and some screenshots.

KPL is based on .NET, and includes its own immersive runtime for doing things like using sprites and collision detection. The tool can generate C# or VB code from the KPL code, which enables kids to learn in KPL and graduate to VB or C#.”

ONJava.com: What Is a Portlet

ONJava.com: What Is a Portlet: “‘Portlets are web components–like servlets–specifically designed to be aggregated in the context of a composite page. Usually, many portlets are invoked to in the single request of a portal page. Each portlet produces a fragment of markup that is combined with the markup of other portlets, all within the portal page markup.’ (from the Portlet Specification, JSR 168)”
Le portlet sono interessanti perché sono un modo di realizzare una pagina web per componenti, ma il framework necessario per realizzare portlet potrebbe introdurre limitazioni e vincoli tali da complicare qualche parte del compito mentre ne semplifica altre.
Questo articolo sembra un buon punto di partenza per iniziare a studiare.

Guide to Using XMLHttpRequest (with Baby Steps) from WebPasties

Guide to Using XMLHttpRequest (with Baby Steps) from WebPasties: “The XMLHttpRequest object is a handy dandy JavaScript object that offers a convenient way for webpages to get information from servers without refreshing themselves.”
Un tutorial eccellente sull’uso di un oggetto estremamente critico per realizzare applicazioni dinamiche, che mosra tutti i lati del discorso, soprattutto il modo (corretto) di fare interrogazioni asincrone.
