Sunday, 29 March 2009. In an attempt to create a video game, I came across the problem of creating a maze (see figure).

Tuesday, 15 October 2013. Mobile Ads do not work (for app developers). In my humble opinion mobile ads just doesn' work for App developers as a mean to generate revenue from their apps. You have an average CTR of 0.21% , but you only get one cent or two cent per click. Meaning that you need millions of viewers per month to get a decent revenue. In my own experience I had an app with AdMob ads, and indeed I got a daily CTR of 0.17/0.2/0.22; much in line with the average CTR found. View my complete profile.

Wednesday, 22 April 2009. NSDateFormatter in OSX 10.4.11. Today I found some strange behaviour in the NSDateFormatter :. If I execute the following code :.

TheTime setStringValue: formattedDateStringTime] ;. Then , instead of displaying the time, it shows me the date. If I add the following line on top :. I cop...
