Why developers matter in understanding the next wave of mobile computing.
Last week, for the second week in a row, IIS administrators have had to face Code Red. More than a simple virus, Code Red could represent a new acceleration in the online virus war and shows that we may not be ready, as an industry, for the era of web services. A Rapid Epidemic Now that I’ve got your attention, let’s take a quick look at how Code Red spread. First of all, there was a simple buffer overflow problem in Microsoft Index Server, for which the company produced a patch. A month later, Code Red starting showing up. However, its rate of growth was relatively slow at the beginning. The true epidemic did not start until July 19th, when Code Red exploded onto the scene, increasing the number of infected servers from just around 300 at 00:15am to 2994 by 7:30am, over 30,000 by 14:40pm and over 300,000 in the 6 hours after that. In other words, in less than a day, Code Red went from a relatively small annoyance to a full blown attack on the net infrastructure. Had no one rung the bell on it, it would have taken only a couple of days for it to…Read More
For the past few weeks, I’ve been experimenting with OmniSky’s new wireless service for the Palm V and I have to admit that it has affected my wireless usage. Running over AT&T’s CDPD network, the service allows Palm V users to get full access to the net at speeds of up to 19.2kbps. Priced at $300 for the modem and a $40 monthly rate for unlimited access, the service is still not cheap but it is starting to approach the reasonable area once you realize how much you can do with it. The basic software package comes with some of the same clips that are available on the Palm VII and a few extra programs like a full mail package which allows you to connect to your POP3 server. However, I decided to get rid of that piece of software once I discovered Ptelnet, a small telnet client for the palm. This allows me to access a Unix server on which I not only have an email client but also a Usenet client, as well as a web browser (lynx) and an FTP client. As a result, this telnet client works as the perfect on the road kit. For more…Read More
