Google Glasses-Scrutiny


I went through all the media and text that is out on the internet about Google glasses. The basic concept seems really innovative.
I don’t know whether all the computing power of the system is contained in those glasses or there is a separate computing hub that powers the glasses. The device needs a compulsory internet connection for basic apps that it showcases .Taking the Indian scenario, the chances of a person owning the device having an internet connection fast enough to send and receive huge chunks of data is low. Another factor that comes into play is the size of the device. Will it be able to deliver high levels of processing power enough to render High-Definition content for movies and moreover games.
Google previously said that the device will be completely voice-operated. Imagine a person talking to his device in the middle of the street asking directions. That would look humorous. When it comes to serious business, it would be highly inconvenient to use your device in workplaces or libraries. What if a person is in the midst of a serious business meeting and has to make an urgent message. But, now it seems they have corrected this by installing a track-pad onto the device. So, they have this problem corrected, but still it would be difficult to type text.
According to Intellectual Property centric blog Patentbolt, Google has just been granted three design patents on 17th of May with one highlighting how its Project Glass could work with hand gestures.

That would add to the ease in operability. But that would not be enough.

The visuals that the device would generate on the Head Mounted Display (HMD) will disrupt the view of the user. It would be really annoying to have your device flash a message on your HMD while you are driving or rather while you are walking on the streets.
It would become necessary to wear the device to execute basic phone services. Though, I don’t see this to be a problem but I’m sure there will be people who will not want to do that.
The applications on the device might be running either on cloud or natively on the device. If the former is the case, then it will be a serious privacy issue, because if it sends and receives data from all kinds of sensors that are planned on it. You actually lose your “Right to Privacy”. This could result in dystopian outcomes.
Overall, if Google does away with the problems stated above (which I am sure they will), it may work but if it doesn’t I guarantee you buddy; this is just another “Product Failure” for a promising and innovative product of Google.

MySQL Table Corruption - Automatic Maintenence

Whether you're running WordPress or any other software powered by MySQL, you are relying on MySQL tables always being available and problem free.

Unfortunately MySQL table corruption is a fact of life. 

Network latency, server shutdown, hard drive running out of space and memory defragmentation are just some causes of MySQL table corruption.

A corrupted MySQL table could render your site useless, lead to loss of revenues and basically make your life a living hell.

MySQL offers two command-line tools to check for table corruption:

* mysqlcheck - uses the SQL statements CHECK TABLE, ANALYZE TABLE, and OPTIMIZE TABLE. To invoke mysqlcheck for checking all of your databases you run: mysqlcheck --all-databases

myisamchk - runs on the raw MySQL files, bypassing the server, myisamchk is faster but unlike mysqlcheck cannot be executed while the server is running.
