Smooth GPS data
...it mostly to "interpolate" between readings - to receive updates (position predictions) every 100 millis for instance (instead of the maximum gps rate of one second), which gives me a better frame rate when animating my position.
Actually, it uses three kalman filters, on for each dimension: latitu...
What are the use cases for selecting CHAR over VARCHAR in SQL?
...ght wondering why their drives are full. In other words, it leads to more predictable growth of the size of a database.
So those are 3 ways an online (OLTP) system can benefit from char over varchar. I hardly ever use char in a warehouse/analysis/OLAP scenario because usually you have SO much dat...

...uirements, then they would have said so. We are not mind-readers, we can't predict every eventuality in each question. That way lies madness.

Does List guarantee insertion order?
...ter science textbook. Just like Queue and Stack, a List is a well defined, predictable and well understood data structure - if the .NET implementation differed (or if it changes) a lot of software would break.

Is it worthwile to learn assembly language? [closed]
...els. As you research assembler you will learn about cpu pipelining, branch prediction, cache alignment, SIMD, instruction reordering and so on. Knowledge of these will help you write better high-level code.
Furthermore, the conventional wisdom is to not try to hand-optimise assembly most of the tim...
Dilemma: when to use Fragments vs Activities:
...But for Activity, it will be a nightmare to manipulate those stuff.
A much predictable lifecycle. As long as the host Activity is not recycled. the Fragments in the backstack will not be recycled. So it's possible to use FragmentManager::getFragments() to find specific Fragment (not encouraged).

Sql Server string to date conversion
...ontrol, then the app can control the format. No matter how much you try to predict your users' behavior, they'll always figure out a dumber way to enter a date that you didn't plan for.
Until Denali, though, I think that @Ovidiu has the best advice so far... this can be made fairly trivial by imple...
Jquery - How to make $.post() use contentType=application/json?
...ad json, will only allow an object or array, not a string--thus why jquery predicts things this way. If you have a server that reads strings, numbers, etc without being wrapped in an object, you must specify the content-type as in this answer.

What techniques can be used to speed up C++ compilation times?
...e the common instantiations among the three files. It is hard to generally predict if the improvement can be significant or not. But one evident fact is that you would lose parallelism in your builds (you can no longer compile the three files at the same time).
Further, if any of these files happen ...
