Resetting your keychain in Mac OS X

I had a couple of weird issues on my MacBoook Air for several weeks now. Every time I tried to use iTunes, it keeps spitting out an error saying, “iTunes can’t verify the identity of the server.” In addition to iTunes, I also had an issue with the App Store. I can’t login, and it’s displaying a blank page. I tried going to an Apple Store, but the wait is 7 hours, so I called Apple Support. Since my laptop is 4 years old, Apple wants me to purchase one-time support fee of $29. I said no thanks. After a couple of hours of googling and troubleshooting, I finally found a fix. All I needed to do was reset my keychain. If you have the issue I had with iTunes and the App Store, try resetting your keychain. I’m glad I didn’t cough up $29 for a simple fix.

11 Attacks on Fiber Backbone

The FBI is investigating 11 attacks on Internet Fiber backbone in the San Francisco Bay Area this past year. The cutting of the fiber cables resulted in the disruption of Internet access to local businesses, as well as residential areas. Is this an act of vandalism or something more sinister? The attacks reveals the vulnerability of the Internet infrastructure. How do you exactly protect hundreds of miles of fiber optic cables? You can’t put up thousands of security cameras as a deterrent. That would be impractical. In this particular incident, the attackers were able to get to an underground vault. Why aren’t these vaults secure? Why aren’t there any surveillance cameras?

Windows 7 and Windows 10

When Microsoft decided to make Windows 10 a free upgrade, it pushed many people that were still on Windows XP to purchase Windows 7, since Windows 7 gets them to the promised land, which is Windows 10. It’s a brilliant strategy by Microsoft to get people who were reluctant in purchasing another Windows product, to actually spend for a new OS. It might be a free upgrade, but you need at least Windows 7 to upgrade to the new OS. We just hope Microsoft delivers on Windows 10, because they have had a spotty record with regards to releasing Windows OS.

Nova OS

Meet Nova OS, Cuba’s Linux-kernel based operating system, built by students of University of Computer Sciences.

The operating system is called Nova OS and the latest available version is 4.0, released March 22, 2013, which is based on Canonical’s Ubuntu 12.04 LTS (Precise Pangolin) and built around the GNOME 3.4 desktop environment.

Yes, that means Nova OS does not use Ubuntu’s Unity user interface, providing users with a traditional layout comprising two panels, using GNOME’s GNOME-Shell interface, but with a custom design.

At the moment, Nova OS 4.0 is distributed in three editions, Escritorio, Ligero, and Servidor. The Escritorio edition is the main one, also known as the Desktop CD, which provides users with a complete GNOME-based desktop environment.
