Volvo working on crash proof car

Yes, what we thought is impossible, is supposedly possible, as soon as 2020, Volvo says. In fact, they’re even releasing concept version of the car next month, which will showcase the car’s abilities. lats60In fact, the car they will be showcasing will be released in 2010. So what does it do? Full collision warning plus full auto break, as well as pedestrian detection.

Volvo states that up until now, they have only focused on protecting the driver from crashing into other vehicles, however they are now focusing on protecting unprotected pedestrians. They also said that it is their first car to use full auto break, a big jump from the previous 50%, thanks to new sensor technology.

The new car utilizes cameras and radars, and if a collision is imminent, the car first warns the driver, and if no action is taken, it automatically does a full auto break.

It appears that Volvo is now marketing it as the first accident proof car.

Why mirroring is not enough

“Journalspace.com has fallen and can’t get up. The post on their site describes how their entire database was overwrittenservers through either some inconceivable OS or application bug, or more likely a malicious act. Regardless of how the data was lost, their undoing appears to have been that they treated drive mirroring as a backup and have now paid the ultimate price for not having point-in-time backups of the data that was their business.”

I’m not an expert in this field, however by the looks of it, it seems the mirror just duplicated the wiped database. As comments on Slashdot stated, you need to do regular backups to tape. It may be expensive, but it is definitely worth it. Quantcast claims that they had 14,000 visitors a month (not as much as Maddox, mind you!) and an Alexa ranking of 106,881.

According to the owner of JournalSpace, the server had two drives, where the data was mirrored between them, however what happened, is one drive had the database wiped, and the other drive just copied the wiped database. According to a data recovery company, the information is lost for good, and so they are shutting down. If anyone’s interested, the server is Mac OS X Server. Supposedly one of the staff sabotaged the server after he left, and they believe that it is quite possible that they did additional damage at a later date.
