Tinyurl.com had on its own 11 characters, bit.ly 6 characters( only half!!!) and now j.mp –only 4 characters wasted. Twitter allows only 140 characters - Need to save two characters in a tweet? You either have to use the SMS language - rework your wording by changing “people” to “ppl” or “for” to “4” for example, or, if you want to include a link, you can use a shorter URL.The natural evolution of shortening websites followed the shrinking idea: Starting with tinyurl.com who had on its own 11 characters, going to bit.ly 6 characters( only half!!!) and finishing with the newest addition, making URLs look like they were getting just a little too long, when Bit.ly introduced j.mp –only 4 characters wasted.

URL shortening too long? j.mp is the answer

No method is perfect – GPS needs clear sky, aGPS improves this but still needs some satellites to be seen, GSM works like a charm if you have lots of antennas but falls dramatically if you’re in a remote place and WiFi positioning is good in cities, but absolutely lacks in remote zones. Only the composition of all can cover all the situations encountered in a normal life – crowded city when going to work and big, empty spaces when going to mountains to relax.

GPS vs aGPS vs WiFi vs GSM localization


GPS is the oldest one from the frameworks available to the large audience. It isn't the first positioning system, but it is the one with the most success and longevity. It started as a military project in 1957. Because of the cold war, once the Russians sent to space the first man-made satellite, a team of scientists started monitoring its radio transmissions. The crucial discovery was that, because of the Doppler Effect, the signal transmitted frequency increases as the satellite approached, and lowers as it continued moved away from them.

The software as industry relies more on reusability and on site modifications. If a programmer finds a piece of code, of course respecting the intellectual property, can easily adapt it to his project. This approach is called adaptive, because these methods focus on adapting quickly to changing realities – no customer knows from the start exactly what he needs from the start.

Agile vs Waterfall





The roots of agile programming as we know it can be traced back to 2001. At Snowbird ski resort in the Wasatch Mountains of Utah, a group of seventeen people met have fun, but also to find common ground on a issue that was too much discussed but no result can be achieved.They were adepts of Extreme Programming, SCRUM, DSDM, Adaptive Software Development, Crystal, Feature-Driven Development, Pragmatic Programming and other agile techniques, joined together by the need for an alternative to documentation driven, heavyweight software development processes.
