Unlock iPhone get Sued

Dell, Solio, Provia and More

August 27, 2007

Today has been a pretty hectic day for me as I was up late at an uncle and aunt’s 50th anniversary party last night (amazing number of years isn’t it?). This AM I had a meeting with the doctor who tells me I am healthy but have higher blood sugar than I should. I would appreciate any of my readers reminding me to not eat chips or cookies going forward. Yes I am serious.   Tomorrow I have major (for me anyway) dental work and I will be at Pepe’s Pizza later this week with college friends and I will not be dieting.

Use Skype, go to Jail

August 24, 2007

OK, I have been writing about Skype almost continually and this is not intentional. There is just a great deal of news about the company lately. For example, George Ou discusses today how a man in the UK was arrested for using a neighbor’s WiFi network. He went on to say he was reviewing a Skype phone which automatically connected to an open WiFi network in an unfamiliar area.

Ixia on Skype Outage

August 22, 2007

You may have seen my recent blog post about what we learned from the Skype outage. I have had much feedback about this article and I found it important enough to publish in an upcoming TMC magazine. I won’t tell you which as I would like you to read them all of course.   One of the letters I received regarding the post was actually something the author allowed me to publish. The quantity of mail I receive where the author wants me not to publish the comments is astounding actually.   The e-mail below agrees with my thoughts regarding the Skype outage and since it comes from Ixia, a testing company no one should be surprised.

Skype Retracts Microsoft Blame

August 22, 2007

In previous posts it was mentioned that Skype blames Microsoft for the recent outage it had last week. More recently Skype has issued a statement saying it does not diectly blame Microsoft for the problem but instead it clarified the Microsoft update patches caused a chain reaction which caused their network to fail.   Here are the details:

1. Are we blaming Microsoft for what happened?
We don’t blame anyone but ourselves.

Videoconferencing

August 21, 2007

TMC is proud to have partnered with SightSpeed to launch a videoconferencing channel on TMCnet which is designed to bring together the community of videoconferencing decision-makers in a single location online.   Expect this channel to be updated frequently and worth bookmarking to keep up to date on the latest in all things having to do with the videoconferencing space.   I have selected some articles from the channel you may find interesting.     Here is some of the current news from the site which could also be of interest:  

Skype Outage Article

August 21, 2007

Jon Arnold and I were both quoted recently in a San Francisco Chronicle article titled Skype reveals outage source, tells customers it won't happen again. The article is extremely well-written, gets perspective from a number of people and weaves each viewpoint into a cohesive whole.   My quote follows below:  
The technology relies on user computers to route phone calls and handle some of the call authentication. There are thousands of computers and servers that are tapped to act as these supernodes in the Skype network.   That reliance has allowed Skype, owned by San Jose's eBay, to keep phone calls free between members and extremely cheap for calls to nonsubscribers. But an outage like last week's reveals the inherent vulnerability in the system when a large number of computers are affected within a short span of time, said Rich Tehrani, chairman of the Internet Telephony Conference and Expo and president of TMC, a communications and technology media company.   "The fate of the users is not in the control of one company, and that's the problem," Tehrani said.
