There are quite a few articles on how to do this around the internet but I noticed the other day that we did not have one so I decided to make a quick post on how to do this. In previous versions of Windows such as XP all you had to do was press F8 at boot time and the administrator account icon would appear on the log on screen so that administrative tasks could be preformed. This is not the case in Windows Vista or Windows 7. Below I will show how to enable the Administrator account using a elevated command prompt.
ActionView::TemplateError (comparison of Fixnum with nil failed) on line #38 of app/views/layouts/base.rhtml
The below error is another error related to upgrading Redmine. I imagine part of the reason I had a lot of errors is because I hadn’t upgraded this installation of Redmine, which we really just use for development, for a long time. In fact the upgrade took this installation of Redmine from 0.8.3 to Redmine 0.9.3. After I completed all of the steps in the Redmine upgrade I attempted to bring up the Redmine site in my Chrome browser but I received a 500 error from the LiteSpeed web server. The resolution was easy and is displayed below along with more details regarding the error.
Adding Redmine Project Error: ActiveRecord::StatementInvalid (Mysql::Error: Unknown column projects_count in field list
I was working on a project today for a client and after the initial research I realized that the project actually warranted an entire sub project account in Redmine. The reasoning behind this was even though the project would be using the same Ruby project code as the primary project this specific side project would need to allow access to the tickets for one of our partners. The easiest way to allow the partners accounts access to only a specific set of tickets, their own wiki, etc. would be to generate a sub Redmine project underneath of the primary Redmine project. So obviously the first thing to do was to add the project so I could start configuring it and this is where I ran into the initial issue. I received an internal server error when attempting to add the sub project within Redmine. Below I describe the issue, what I think caused the issue, and the end resolution that allowed me to start adding sub projects within Redmine again.
How to Switch Between Different Versions of GCC and G++ in Backtrack 4 Final (Or Any Version Of Ubuntu)
I had a Backtrack user on IRC today asking about using different versions of GCC in Backtrack. Since Backtrack is based on Ubuntu Linux this article will apply to any version of Ubuntu but I wanted to write something specifically for Backtrack users. There are many reasons for needing different versions of GCC and G++. One of the main ones is installing a program which requires a kernel module to be built. What happens is that if the kernel was built with GCC-4.1 and GCC has since been updated to GCC-4.3 sometimes the build will fail dude to a kernel/GCC –version mismatch. Below I detail the steps to downgrade from GCC-4.3 to GCC-4.1 on Backtrack Linux.
A friend of mine who is a DJ dropped one of his friends external hard drives in the dark the other night while spinning at a club. Once he got home he attempted to plug his friends external USB hard drive, which is a 1TB SimpleDrive (model #96300-41001-170), into his computer but it was not being recognized. Once he tried a couple of other things he gave me a call to see if I could look at it. Without going into details about what was wrong with the hard drive itself I thought others might find it useful to have instructions including pictures about how to remove the hard drive from the SimpleDrive case. Below I describe how to remove the hard drive from a external USB 1 Terabyte SimpleDrive.
