jQuery Mobile: document ready vs. page events
...e content for that page is “enhanced” (styled)
A transition (slide/pop/etc) from the existing page to the new page occurs
This is a average page transition benchmark:
Page load and processing: 3 ms
Page enhance: 45 ms
Transition: 604 ms
Total time: 670 ms
*These values are in millisecond...
Do you (really) write exception safe code? [closed]
...If you are catching everything in your top control scope (thread, process, etc.), then you can be sure that you will continue to run in the face of exceptions (most of the time). The same techniques will also help you continue to run correctly in the face of exceptions without try/catch blocks ever...

There will be 16 patterns in total. If you take advantage of rotational and reflectional symmetry there will be even fewer.

Perforce for Git users? [closed]
...s a pretty traditional revision control system (closer to CVS, Subversion, etc.) and normally is considered to be less complicated than modern distributed revision control systems.
Trying to map commands from one to the other is not the right approach; concepts from centralized vs. distributed revi...
What is an existential type?
...definition, list all possible uses, their relation to abstract data types, etc.) because I'm simply not knowledgeable enough for that. I'll demonstrate only (using Java) what this HaskellWiki article states to be the principal effect of existential types:
Existential types can be used for severa...
What is the optimal algorithm for the game 2048?
...ontaining no hard-coded intelligence (i.e no heuristics, scoring functions etc). The AI should "know" only the game rules, and "figure out" the game play. This is in contrast to most AIs (like the ones in this thread) where the game play is essentially brute force steered by a scoring function repre...
What is a NullPointerException, and how do I fix it?
...ou should know, Java types are divided into primitive types (boolean, int, etc.) and reference types. Reference types in Java allow you to use the special value null which is the Java way of saying "no object".
A NullPointerException is thrown at runtime whenever your program attempts to use a null...
How can I sort arrays and data in PHP?

Your rewrite contains a lot of details (pass by reference, big table etc.), but that detail distracts from the smooth introduction to the core topic of the workings of the comparison function, IMHO. I explicitly refer to the manual several times on purpose, because that's where such detail sho...
What kinds of patterns could I enforce on the code to make it easier to translate to another program

The amount of machinery you need to do this well is vast (especially if you want to be able to do this for multiple languages in a general way), and then...
