Fix “bind() to 0.0.0.0:80 failed (98: Address already in use)” nginx error

Recently, I have been buying VPSes with various companies to test setting up a light, fast and efficient Linux box to run some of my sites.

For the last two major versions of Mozilla Firefox on Windows 7, I have been getting a “Software Update Failed. The update could not be installed.

WindowsBackend object has no attribute iso_path error in Wubi Ubuntu installation

After almost a year of not using Ubuntu, I tried out Ubuntu 11.10, codenamed Oneiric Ocelot (what’s up with the harder-to-spell names?). Since this was a trial run, to see how things had changed, I decided to install Ubuntu from within Windows, using the Wubi (Windows based Ubuntu) installer. Wubi installs Ubuntu in a folder […]

“Could not lock /var/lib/dpkg/lock’ error on Ubuntu

In Ubuntu, you can install programs and packages in three ways – terminal commands (sudo apt-get install), Synaptic package manager (which does not come installed by default anymore) and Ubuntu Software Center (which is the preferred way of installing apps on Ubuntu now).

Stop Facebook face recognition feature in photo tags

Photo uploading and sharing is a big part of the social experience on Facebook. The number of photos uploaded on Facebook every year is in the billions, beating out even dedicated photo sharing sites like Flickr.
