Greenlet Vs. Threads
...l when there's a lot of work to be done in userspace, and that's typically CPU-heavy stuff. Concurrency is useful for breaking apart problems, enabling different parts to be scheduled and managed more easily in parallel.
Greenlets really shine in network programming where interactions with one sock...
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...
Ternary operator is twice as slow as an if-else block?
...itional with 1000 iterations: 47710ms
My system details:
x64 i7-2720QM CPU @2.20GHz
64-bit Windows 8
.NET 4.5
So unlike before, I think you are seeing a real difference - and it's all to do with the x86 JIT. I wouldn't like to say exactly what is causing the difference - I may update the post ...
What do we mean by Byte array? [closed]
..., numbers from -128 to 127, single characters using ASCII e.g. 'a' or '%', CPU op-codes), each byte in a byte array may be any of these things, or contribute to some multi-byte values such as numbers with larger range (e.g. 16-bit unsigned int from 0..65535), international character sets, textual st...

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 ...
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...
