Performance of Ajax Applications on Mobile Devices

Mikko Pervilä has released his execellent Masters Thesis on measuring Ajax performance on different mobile devices

From the Abstract:

This thesis evaluates the presentational capability and measures the performance of five mobile browsers on the Apple iPhone and Nokia models N95 and N800. Performance is benchmarked through user-experienced response times as measured with a stopwatch. 12 Ajax toolkit examples and 8 production-quality applications are targeted, all except one in their real environments. In total, over 1750 observations are analyzed and included in the appendix. Communication delays are not considered; the network connection type is WLAN.

Results indicate that the initial loading time of an Ajax application can often exceed 20 seconds. Content reordering may be used to partially overcome this limitation. Proper testing is the key for success: the selected browsers are capable of presenting Ajax applications if their differing implementations are overcome, perhaps using a suitable toolkit.

Blood, Bullets, Bombs, and Bandwidth

A short article on internet-contractors in Iraq. It resembles a Bruce Sterling short story.

Ryan Lackey wears body armor to business meetings. He flies armed helicopters to client sites. He has a cash flow problem: he is paid in hundred-dollar bills, sometimes shrink-wrapped bricks of them, and flowing this money into a bank is difficult. He even calls some of his company's transactions "drug deals" – but what Lackey sells is Internet access. From his trailer on Logistics Staging Area Anaconda, a colossal US Army base fifty miles north of Baghdad, Lackey runs Blue Iraq, surely the most surreal ISP on the planet. He is 26 years old.
