In the past I used CentOS Linux the open source RedHat Enterprise Linux clone but these days I find myself using Ubuntu Linux more and more often because so many more packages that clients want installed are more up to date. One command I used to use on CentOS all the time was the yum whatprovides command which would allow me to search for specific applications, scripts, libraries, etc. to figure out what packages I needed to install. The command that is similar on Ubuntu is apt-file which does not come installed by default. Below I show the output of an example yum whatprovides command on CentOS Linux followed by what needs to be done to use apt-file on Ubuntu Linux.
The question has come up numerous time on how to get a refund on an iPhone app or iPod Touch app purchased from the iTunes store so I decided to write a quick howto. After completing the below process Apple should respond within a couple days and refund your money with a week or so as long as the request for a refund is valid. It is possible you won’t get a response at all if the request to refund the cost of the application is not valid. Follow the directions below to complete a refund request for applications purchased from the iTunes Store.
I believe the QualXServ Service Agreement which comes installed on Dell netbooks, laptops, and desktops is really just a PDF file. The PDF file is the service agreement for in-home or on-site repair which typically comes with the purchase of a new Dell computer. When you remove the application from your installed Programs the PDF is removed from your system. I recommend simply copying the QualXServ.pdf file from its default location to another location before removing the application from your computer just in case you happen to need it. Follow the directions below to save the file to a familiar location and then remove the application from your PC.
I recently updated iTunes and QuickTime on my Windows 7 PC and afterwards noticed that when opening a .PSD (Photoshop Document) file that instead of opening in Photoshop the file opened in PictureViewer. I wasn’t even familiar with PictureViewer at first however after a little searching I realized that PictureViewer is now installed with QuickTime by default which is really annoying since I already have dozens of picture viewing applications. Anyhow what it meant was that I needed to modify how file types associated to applications which is what is described in more detail. I will first describe how to change a single file type to match a single application and then I will describe how to associate a single program to many file types at the same time.
Yesterday I needed to upgrade a single application on CentOS Linux. First I figured out that the application was part of the coreutils RPM package which is currently only available up to version coreutils 5.97-23 on CentOS. The current coreutils package is already up to coreutils 8.5 and upgrading coreutils is near impossible on CentOS because of other package requirements that it needs. Below are instructions on how to download the coreutils source, build the coreutils applications in a new directory, and then upgrade one application.
