The science (or art) of hiding messages is called steganography , and in the digital age, can be used to hide secret messages in innocent-looking images. Looking at the picture, you have no idea there’s a secret message hiding inside, but with the correct tools or passwords, the secret message can be revealed.

Last week we asked you if you would pay to watch YouTube videos, following Google’s announcement of subscription-based YouTube channels. The results were pretty much unanimous, and if we go by them, it seems that Google’s decision might not be the most successful one. Only time will tell whether users really stick to this opinion, [...]

It was only 15 years ago that the best you could do to find a person online was look for him on ICQ and hope you find his name. If you managed to do that, you were actually nowhere nearer to knowing anything about this person, except for the fact he owns an ICQ account. If you were very brave, you might have requested to add that person to your contacts, just to see what happens.

All the tools we recommend are good ones, and we usually give you more than one option, so how do you go about choosing one? Which one is really the best?

For many of us, Twitter is fine just the way it is. Despite what you may think, I’m not going to say otherwise. Twitter truly is fine just the way it is. The thing is, and much like everything else, it can also be better, and making it better doesn’t necessarily involve using a third-party [...]

One of the biggest things that happened this week was the launch of paid channels on YouTube. While limited in number and availability to start, this is not something that’s going to stay small for long. YouTube is a video platform that’s always been completely free, and although ads are becoming more and more common, asking people to pay for channel subscriptions is quite a leap of faith from Google. Or is it?

I have been looking for something that could clean up my iPad for me and, according to iMobie, PhoneClean is the program to do that. The free program that claims to free space on your iPhone, iPad, or iPod Touch by deleting files that should be useless to you, such as temporary files, cached and offline files, cookies, script files, and media files that failed to sync properly. On paper, this should be quite useful, especially if you own a 8GB or 16GB iDevice. But does it really work?

Today, you can have such things as self-destructing online messages, self-destructing photos and videos, temporary webpages, and even disposable email addresses. So in that spirit, why not have self-destructing tweets? Twitter’s inherent timeliness is exactly what makes efemr a good idea.

Ever since I was a little kid, I’ve adored optical illusions. Believe it or not, but 1993 found me browsing my parents’ hefty Escher art book, looking for more and more drawings I couldn’t quite figure out. This fascination continued through the famous Autostereogram era, when I learned to see those cool 3D images in seconds, becoming a source of jealousy to all my cross-eyed friends.
