Sometimes we make mistakes. Fortunately, sometimes we can undo our mistakes. Undo is a command or option in many computer or phone programs that undoes the last change made, reverting the data or program to its state before the change was made.

Adobe Photoshop has long been one of the premier image-editing computer programs available. If you're a graphic designer, professional photographer, or illustrator, this is probably what you use. But it isn't cheap, it doesn't run on all operating systems; and it probably includes more functionality than is needed for most hobbyists, scientists, or students, adding to its complexity. Fortunately, there are free options to Photoshop, including some that are easy to use. Below, we review three of the most popular applications we've used. (We should mention that web-based
Utilities exist to help you find and clean your system of old and unused files. This allows you to free up disk space. In this article we will look at installing and running on personally-managed Linux systems a utility that's free and available not only for many Linux distributions, but also Windows and Mac OSX.
Before we begin, it is important to keep in mind that running utilities that delete files with elevated privileges can break a system. One must always exercise care when doing so. Always keep in mind when running BleachBit that its file deletions are
Due to the interest received towards development/programming, in this blog post we're going to take the time to detail how to get started with web development using a local virtual machine environment. We'll also go over how to write a simple "Hello World" script in PHP.

Microsoft Windows Vista turned 10 years old and reached its end-of-life (EOL) on April 11, 2017. As such, Microsoft no longer offers security updates, technical support, software, and content updates for Vista. Machines running Vista no longer meet UT minimum security requirements, leaving these systems vulnerable to attacks. In addition, new hardware, software, and third party software updates may no longer work with Windows Vista. In short, keeping Windows Vista installed on your systems is a disaster waiting to happen.
Microsoft has ended support for older versions of its popular web browser Internet Explorer (IE) as of Tuesday, January 12, 2016. After that date, Microsoft will no longer be releasing security updates, patches, or bug fixes for all versions of Internet Explorer except Internet Explorer 11 and later. After January 12, if you are still running an unsupported version of IE on the campus network, you are putting the University at risk.
In an effort to keep the campus computing environment safe and secure for everyone, all Windows computers should be upgraded to IE 11 as soon as
If you are running Windows 8 (not 8.1), you need to upgrade ASAP! The January 12, 2016 Patch Tuesday contained the last updates for Windows 8. If you are still running Windows 8, it's time to update to Windows 8.1 or Windows 10, or risk exposing your PC to unpatched security risks.
Thanks to a quirk in Microsoft's support lifecycle, Windows 8 is no longer supported. This is because Windows 8.1 is considered a service pack to Windows 8, and Microsoft provides two years to upgrade to a service pack before discontinuing support for the previous release. Since
