How do you crash a JVM?
... as blowing the stack via recursion, running out of heap memory via object allocations, or simply throwing RuntimeException. But this just causes the JRE to exit with a StackOverflowError or similar exception, which, again is not really a crash.
So what's left? I'd really love to hear what the auth...
What can you do in MSIL that you cannot do in C# or VB.NET? [closed]
...nds by returning the value of method B such that method A's stack can be deallocated once the call to method B is made.
MSIL code supports tail recursion explicitly, and for some algorithms this could be a important optimization to make. But since C# and VB do not generate the instructions to do th...

Create a list from two object lists with linq
...ed execution, using Concat would likely be faster because it avoids object allocation - Concat doesn't copy anything, it just creates links between the lists so when enumerating and you reach the end of one it transparently takes you to the start of the next! This is my point.

Difference between char* and const char*?
...e points, as it could result in Undefined Behavior.
String literals may be allocated in read only memory regions (implementation defined) and an user program should not modify it in anyway. Any attempt to do so results in Undefined Behavior.
So the only difference in that case (of usage with s...
Making the Android emulator run faster
...for the AVD Manager to pick up the Intel Atom (x86) CPU option. Tip: Don't allocate too much RAM. With 1GB RAM, emulator failed to start (with GPU) but with 512MB RAM it ran smoothly and booted really quickly (again with GPU).

In Clojure, when should I use a vector over a list, and the other way around?
...
Vectors have O(1) random access times, but they have to be preallocated. Lists can be dynamically extended, but accessing a random element is O(n).
