Installing the Opera web browser on Fedora

2013-05-20

I use Firefox as my primary web browser, however I like to have at least one other browser installed as a secondary browser, which can be useful testing. Recently I found that I was having stability problems with Google Chrome on my Fedora 16 work station (in particular with Flash), so decided it would be a good time to take another look at Opera as a replacement.

Unfortunately there is no yum repo available for Opera, so you will have to go to their website and download the correct .rpm file:

Download Opera

Adding a read-only MySQL user

2013-03-06

Sometimes you may need to let a user have access to your MySQL database, for example for viewing data directly during testing or for running reports, but you do not want these users to update data or make schema changes.

It is actually quite easy to set up a read-only account in MySQL using the GRANT statement, which is ideal for these purposes.

Connect to your database as root, then add your new user like so:

 1 



CREATE USER 'tester'@'%' IDENTIFIED BY 'password';
