Dynamic programming futures

JavaScript, Perl, PHP, Python, Ruby, and other dynamic languages are remaking the Web and bringing programming to the masses. Where should developers place their bets?

When a decision must be made, some believe it makes sense to go with popularity. The rich will get richer. PHP is the first language that many people learn after mastering HTML, and it will always be as comfortable as a childhood home. PHP server platforms from Zend Technologies offer better performance, making it possible to write a serious application in the language.

But will PHP be able to shake the casual structure that encourages beginners to whip up spaghetti code? Will it be able to continue to mix the presentation layer and the application layer without driving everyone insane? Will Zend's collection of server optimizations provide enough performance to overcome any limitations of the language?

Others suggest that developer passion will produce the dominant language. Perl and Python attract some of the smartest minds who see programming as a craft. Their insight and devotion to creating elegant solutions is bound to produce a great platform in two years.

Hearts and minds

The same credibility with programming hipsters, however, can scare away the bulk of programmers and limit a language to a niche. This isn't fatal, but it can come close if the masses flock to something simpler. The cool library writers can follow demand.

Some want to place their bets on Ruby on Rails, a striking and elegant solution that produces sophisticated results in no time. A few lines of code produce a full interface with all of the pages necessary to create, update, and delete records.

This simplicity often turns into shackles when the programmers reach the edge of the framework's capabilities. Changing little details or producing slightly unorthodox output can be maddening.

There are many other options. Some developers love Groovy, the dynamic language integrated with the Java API. A programmer gets the rock-solid foundation of compiled Java code mixed with the flexibility to diddle with the Java objects in real time.

And then there are others who see languages such as JavaScript rising from the browser and colonizing the server. A unified platform makes everything simpler. Yes, Netscape wanted this to happen years ago, but thanks to the lightning performance of the new JavaScript semi-compilers, the language is bound to look even more attractive.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
