  A Hello, World Servlet


Servlets are the pure Java solution to handle web requests. Many application will use servlets instead of JSP and others will use servlets in conjunction with JSP. Experienced JSP programmers use servlets in conjunction with JSP to create clearer and simpler applications. The servlets handle Java processing: form handing, calculation and database queries. JSP formats the results. Servlets belong in WEB-INF/classes. On this machine, the source is in Java source in /var/www/hosts/www.caucho.com/we...

  Is Scala Only for Computer Scientists?


I have experience struggling through these kinds of things andI know enough about the subject that I can understand why they did it that way. But my concern is that this should be an example that a beginner could understand, and they can't. There's too much depth exposed. Here's the example, which is written as a script: import scala.io.Source._ case class Registrant(line: String) { val data = line.split(",") val first = data(0) val last = data(1) val email = data(2) val payment = da...

  Scala, Patterns and The Perl Effect


He tried to understand that one concept for a couple of months before it made sense to him. Admittedly, partial functions are not intuitive for anyone who has been schooled in traditional programming, but still, looking at the problem he was trying to solve it seemed like James was required to expend too much effort relative to the simplicity of the problem (as he pointed out, now that he understands the concept it seems straightforward). He showed me the code, and it was basically a situa...

  Are frameworks making developers dumb?


Last week I got to take interviews to hire senior java developers with around 5 years of experience. But after the interview process is over I felt like the frameworks makes developers life easier but at the same time making them dumb.Everyone puts almost all the new frameworks on their resume claiming they have "Strong, working experience on Spring, Hibernate, Web Services etc".Here is how the interviews went on.Me: You have used Spring in your latest project. What are the advant...

  Five-minute Multimethods in Python


So what are multimethods? I'll give you my own definition, as I've come to understand them: a function that has multiple versions, distinguished by the type of the arguments. (Some people go beyond this and also allow versions distinguished by the value of the arguments; I'm not addressing this here.) As a very simple example, let's suppose we have a function that we want to define for two ints, two floats, or two strings. Of course, we could define it as follows: def foo(a, b): if...
