If youre a web developer who builds Ajax-driven applications and wants to learn how to use this technology for making more secure web forms, then look no further. Welcome to the third part of a series focused on making web forms safer with Ajax. Made up of four comprehensive tutorials, this series clarifies how to generate different types of challenge strings via Ajax, which can be incorporated into any existing HTML form with the purpose of protecting it against attacks.
– Introduction
Now that you’ve been introduced to the main subject of this series of articles, it’s time to recall the topics we discussed in the last article. In that tutorial I went through the development of a simple Ajax-based application that could dynamically generate a bunch of elementary …

The HTC Touch Diamond 2 is similar to the Touch Pro 2, except it lacks the keyboard, speakerphone and conference calling capability. And though it’s a fine phone, I prefer the original Touch Diamond’s design.

Everything I said about the software on the Touch Pro 2 holds right with the Touch Diamond 2. It’s all a fantastic implementation of the WinMo platform and looks pretty.

But the TD2 hardware doesn’t blow me away. For one, it lacks the angled backside of the original Touch Diamond, though some may have considered that excessive design. But I loved the way that design tapered the Touch Diamond. With the TD2, the phone is much more boxy and straight forward, lacking the same chic feel as its predecessor. The metallic silver body feels somewhat sterile, and the only real design flourish is a silver patch on the back. It’s also slightly thicker than the original (11.5mm vs 11.3mm)

Obviously the TD2′s screen is larger and better, the guts are a small more powerful and the battery life is improved from the original TD, but I can’t help but want more from this follow-up.

Still, if you don’t need the keyboard—or the extra heft—and want this new HTC UI, pay attention to the Touch Diamond 2 when it finally launches in the second half of this year. It may be worthwhile.

Like Lam, I will forever be infatuated with midrange Sony Ericsson phones. SE knows what their devices can and can’t do and they work within those limitations. The gesture-controlled, designer T707 is no different.

This T707 is essentially a repackaging of core Sony Ericsson phone tech over the last couple years, but in a flashy new shell. Utilizing the rear camera, you can do things like silence a call or alarm by waving your hand over the camera. And one thing I have to give SE credit for is that they always make sure the UI design is fresh looking. the backend programming may essentially be the same, but they keep updating the visuals so as not to look stale.

Other than that, the T707 has eye-catching colors, sleek design and is otherwise a wholly ordinary dumbphone.
