Android: AsyncTask vs Service
...g: Android will not keep your app alive just because your app is using the CPU. It has to have some way of knowing that your app still has work to do; that's why Services are registered with the OS, and AsyncTasks aren't.
Multithreading
AsyncTasks are all about creating a background thread on whic...

Creating an object: with or without `new` [duplicate]
...ng to some specific implementation (say, a computer with an x86-compatible CPU) is needlessly restrictive and leads to a lack of rigour/provability within the scope of the rules defined by the C++ standard. The C++ standard gives rules about storage duration, not about some hypothetical data structu...

Why is an int in OCaml only 31 bits?
...for a simple integer.
Also, you cannot pass such an integer object to the CPU to perform fast integer arithmetic. If you want to add two integers, you really only have two pointers, which point to the beginning of the object headers of the two integer objects you want to add. So, you first need to ...

When is assembly faster than C?
... uint64_t for 32x32 => 64-bit multiplies fails to optimize on a 64-bit CPU, so you need intrinsics or __int128 for efficient code on 64-bit systems.
_umul128 on Windows 32 bits: MSVC doesn't always do a good job when multiplying 32-bit integers cast to 64, so intrinsics helped a lot.
C does...
How does Java handle integer underflows and overflows and how would you check for it?
...r absolute value than the computer can actually represent in memory on its CPU. So underflow does not apply to Java Integers. @BalusC
