Code-first vs Model/Database-first [closed]
... Model First doesn't support user-defined SQL functions (at least in EF4, don't know if this has changed). With Database First, you can import UDFs and use them in your LINQ queries.

SecurityException: Permission denied (missing INTERNET permission?)
...ms too. It's is especially important when your project set targetSdk to at least 23 as then you must support new permissions model (detailed documentation). If you are not ready, ensure you keep targetSdk to at most 22 as this ensures even new Android will use old permission system when your app is...
STL or Qt containers?
...wth, which is more wasteful), but it's important to note that you could at least implement this feature, if need be.
The same is true of doubly linked lists, which could use XOr linking to drastically reduce space used. Again, this is impossible with Qt, due to it's requirements for growth and COW.

Getting multiple keys of specified value of a generic Dictionary?
...es, only the keys, so any search over it using a value is going to take at least linear time. Your best bet is to simply iterate over the elements in the dictionary and keep track of the matching keys or switch to a different data structure, perhaps maintain two dictionary mapping key->value and...

Fastest sort of fixed length 6 int array
...or any optimization, it's always best to test, test, test. I would try at least sorting networks and insertion sort. If I were betting, I'd put my money on insertion sort based on past experience.
Do you know anything about the input data? Some algorithms will perform better with certain kinds o...

In addition there are at least 3 Backbone boilerplates that include Lo-Dash by default and Lo-Dash is now mentioned in Backbone’s official documentation.
Check out Kit Cambridge's post, Say "Hello" to Lo-Dash, for a deeper breakdown on the differe...
Does JavaScript have the interface type (such as Java's 'interface')?

What is dynamic programming? [closed]
...tring, the recursion branches three ways, meaning it grows at a rate of at least 3^n – indeed, even faster since most of the calls reduce only one of the two indices, not both of them.
So how can we make the algorithm practical? The important observation is that most of these recursive calls...
Structure padding and packing
... is MUCH slower). You could arrange the variables in the program until the least padding is done (as it was greatly exemplified in some other answers) but if that's not enough you could explicitly disable padding, which is what packing is.
