git: Error: Some Local Refs Could Not Be Updated; Try Running ‘git remote prune origin’ To Remove Any Old, Conflicting Branches

Lately I have been working on a Ruby project that has a bunch of different branches that various developers are working on. One of the development servers has multiple virtual hosts and at certain points in the code release cycle the various virtual hosts could be completely split from the main branch of Ruby code either because of a bug fix, a specific feature, or any number of other reasons. The other night I needed to bring one of the virtual hosts to a near production release to test some features of a product that uses the web application to record data and when I attempted to “git pull” I received an error which is described in detail below along with what I ended up doing to resolve the problem.

Windows 7: Schedule A chkdsk On Reboot

My Dell laptop has been claiming there is a hard drive issue for some time however when I reboot and let Windows 7 scan the drive it either doesn’t scan the drive or it scans the drive and still claims there is an issue. I believe the drive doesn’t have any major issues and that it has something else to do with the fact that it is a solid state drive. To get past the problem of Windows always claiming that it needs to scan the drive on reboot I scheduled a scan for the next reboot. Below is information on how to schedule a chkdsk scan on next reboot.

LiteSpeed Error: [STDERR] uninitialized constant Rack::Handler::LSWS::RewindableInput

Awhile back I upgraded the “rack” gem on one of our CentOS Linux servers that runs LiteSpeed and Ruby. The upgrade took the rack gem from rack version 1.0.0 to rack version 1.0.1. After upgrading the Rack gem I attempted to visit the site located on the server where the gem was updated only to receive a 503 error from LiteSpeed. During the troubleshooting process I looked at the LiteSpeed error logs and noticed errors that lead me back to the Rack gem I had just updated. Below I describe the error in more detail and what can be done to resolve the issue of rack-1.0.1.

Canfield Imaging Systems: Backup VISIA SQL Database And Upgrade VISIA 4.2 To VISIA 5.0

One of my clients uses VISIA medical imaging software from Canfield Imaging Systems for various forms of medical research projects. They have had the VISIA software and imaging station for a year or more and recently needed to upgrade the software to take advantage of some new features available in VISIA 5.0. The client’s VISIA installation was at VISIA 4.2 so it required a major update to get to VISIA version 5.0. Upgrading the software is fairly easy but it is important to make sure you have current backups before the upgrade begins. Follow the directions below to first backup your the Microsoft SQL Server, backup the VISIA files, and then proceed with upgrading VISIA 4.2 to VISIA 5.0.

Redmine Error Moving Issue Between Projects: Failed To Save 1 Issue On 1 Selected

I had a Redmine ticket I had been working on with our customer support team at work. After working through the initial ticket that was loosely related to a customer initially ended up being a larger issue and I decided to move the ticket to an engineering project as that is where I actively work tickets typically. When I attempted to move the ticket I received an error stating that it had failed to save. Below I describe what the issue ended up being and how I temporarily modified a setting so I could move the ticket.
