Paraphrased suggestions from a Wired magazine article to make your passwords harder to crack - Don't reuse passwords. If you do, a hacker who gets just one of your accounts will own them all. If you must a dictionary word as your password, then string several together into a pass phrase. Avoid standard number substitutions. Think “P455w0rd” is a good password? N0p3! Cracking tools now have those built in. Use the longest possible password. Enable two-factor authentication when offered.  Give bogus answers to security questions - not something hackers can get through social-engineering Scrub your online presence so that your personal information isn't easily available. Use a unique, secure email address for password recoveries. Also see:  Don't let Chrome & Firefox remember your passwords on a shared computer

"Through 20 years of effort, we've successfully trained everyone to use passwords that are hard for humans to remember, but easy for computers to guess."  - XKCD While some websites have a password strength checker to gently suggest that a chosen password may not be good enough others don't give you the liberty of choosing your own password pattern while framing one. Some websites enforce rules that THEY think will be right for their users. They don't care if devising good passphrases or using the shift-to-the-right method work better for you. As a result of this, users will have to break their pattern of framing & the chances of forgetting a password are higher. To me, a reasonable password policy is one that allows alphanumeric and special characters and is of five characters or more. I have been collecting & seeking from friends, examples of whimsical password policies that they encounter online. Here is a list of websites that...

My wife and I built a simple Windows 8 Store geo-location based app called GeoBuzz . It is a free app that lets you discover the world around you. It uses your location coordinates to fetch geo-tagged articles from Wikipedia about or related to the places around you.

Where in the World? is a simple game that is a mashup of Picassa & Google Maps. This geography game lets you view public photos stored by users around the world on Picassa and guess where they were taken. There is no information on how exactly points are scored. The closer your guess is about where a geo-tagged photo is shot, the more points you win. I noticed that if your guess about the location is close to 150 kilometers, you get 600 points while there are no points if your guess is more than 5000 kilometers away. Each round has 5 different photos and you can play unlimited rounds. There is hardly any element of competition. The overall score is not logged. The game could have been better designed and also adapted as a mobile app. GeoGuessr is a similar geography game. Wonder which came first?
