Google and Sprint WiMax Deal

Saturday, July 28th, 2007

WiMax is the next generation wireless technology that will allow wireless broadband access for the “last mile” with DSL speeds. The promise of WiMax is that it will operate over large distances that lie outside the reach of traditional WiFi networks.

Sprint is betting on this new technology and building up a network ahead of the competition. The Reston based telecommunications provider is planning to roll out WiMax networks in Boston and Chicago at the beginning of the second quarter.

Under the revenue share deal with Google Sprint would provide the network access and Google would contribute it’s saech capability and free applications such as instant messaging, e-mail and online calendars.

At the moment nobody seems to be able to catch up with Google’s drive to conquer and dominate new emerging technologies. The free applications only serve as the backbone on which Google seeks to expand it’s ad network.

Bluehost CPU quota

Monday, July 2nd, 2007

The CPU quota is surrounded by a lot of mystery, speculations and rumours. Recently, Alligosh, Bluehost’s principal systems administrator dropped into the bluehost forum and gave an exact definition of what constitutes the CPU limits.

The Bluehost CPU quota defined:

The CPU quota is calculated using a set number of runtime CPU seconds over a set number of realtime seconds.

With us, if you use more than 40 CPU seconds over a 60 realtime second period, the cpu quota system will suspend the website until the average over the last three minutes is below 40 CPU seconds. The three minute average is calculated every 15 seconds for the previous three minutes. As soon as your average is below the 40 CPU seconds, you will be unsuspended.

Also, processes are not terminated for going over the quota, as we don’t like killing half done processes. After the process finishes, it’s entire CPU usage is added into the last minute of processes.

If you have 200 processes in a minute that each use .5 CPU seconds, it will get you suspended. If those same processes take two minutes, you won’t get suspended.

Since the last sentence didn’t make any sense Alligosh later clarified that he meant to say .4 CPU seconds which makes sense again.
