About SSL Certificates

A SSL certificate is a way to encrypt a site’s information and create a more secure connection. Additionally, the certificate can show the server’s identification information to site visitors. Certificate Authorities can issue SSL certificates that verify the server’s details while a self-signed certificate has no 3rd party corroboration.

What the Red Means

The lines that the user needs to enter or customize will be in red in this tutorial!

Emoji are extremely popular picture characters and emoticons that are an integral part of Japanese tech culture and communication, and now with OS X Lion onward (yes, Mountain Lion and 10.9 too), the Emoji character set is available to everyone on a Mac regardless of your localization settings. They’re quickly taking the world by storm with their inclusion on the iPhone and iPad keyboards as well, and using them on the Mac is a fun way to emphasize dialog and messaging between people. Some of the characters are pretty funny so even if you have no intention on using them they’re fun to browse through.

The best Linux file system, Ext2 or Ext4?

Google, which knows a thing or two about fast systems has decided, for their purposes anyway, that Ext4 is the best and close to the fastest file system of all.

Google’s Michael Rubin, a senior staff engineer, wrote, “Google is currently in the middle of upgrading from ext2 to a more up to date file system. We ended up choosing ext4.”

Rubin then explains, “The driving performance reason to upgrade is that while ext2 had been ‘good enough’ for a very long time the metadata arrangement on a stale file system was leading to what we call “read inflation”. This is where we end up doing many seeks to read one block of data. In general latency from poor block allocation was causing performance hiccups.”
