Can you trust in Wikipedia?
Question: My daughter's homework assignment asked her to use Wikipedia as a source for her research. Is Wikipedia reliable?
Answer: Wikipedia contains a wealth of interesting information; however, it shouldn't be trusted as a reliable academic source. Content on Wikipedia is written collaboratively by anonymous users, which means anyone can contribute. The site does have a peer review process to prevent errors, but there have been several instances on Wikipedia where false information has been published. Talk to your daughter's teacher and recommend Scholarpedia.com. It uses the same concept as Wikipedia, except to contribute you must be a university faculty member or researcher. Any content they contribute is reviewed by other experts.
Free photo editing
Q: On your radio show, I heard you mention a free alternative to PhotoShop. What was that software called again?
A: Paint.NET is a cross between Photoshop and Windows' built-in MS Paint. This download was created as a free replacement for MS Paint. The tools are easy to use and include options to add text, patterns, shapes and gradients to any photo using layers. You can sharpen images, remove red eye and add effects such as motion blur.
