Do asynchronous operations in ASP.NET MVC use a thread from ThreadPool on .NET 4

...ons (such as database and network calls to remote services). If you have a CPU intensive operation, asynchronous actions won't bring you much benefit. So why can we gain benefit from I/O intensive operations? Because we could use I/O Completion Ports. IOCP are extremely powerful because you do not...

How can you do anything useful without mutable state?

... every object every time something in its state changes, I'll spend all my CPU time doing nothing but constructing objects. I'm thinking about game programming here, where you've got lots of things moving around on the screen (and off-screen) at once, that need to be able to interact with each other...

What are the barriers to understanding pointers and what can be done to overcome them? [closed]

... Take a basic CPU, say something that runs lawnmowers or dish washers and implement it. Or a very very basic subset of ARM or MIPS. Both of those have a very simple ISA. – Daniel Goldberg Dec 12 '09 a...

Simple way to encode a string according to a password?

... repetition. Including the iteration count ensures that you can adjust for CPU performance increases over time without losing the ability to decrypt older messages. A password alone can be as safe as a Fernet 32-byte random key, provided you generate a properly random password from a similar size ...

What is the strict aliasing rule?

...ut aliasing, it can omit those instructions, load buff[0] and buff[1] into CPU registers once before the loop is run, and speed up the body of the loop. Before strict aliasing was introduced, the compiler had to live in a state of paranoia that the contents of buff could change at anytime from anywh...

Fastest way to determine if an integer's square root is an integer

...that works ~35% faster than your 6bits+Carmack+sqrt code, at least with my CPU (x86) and programming language (C/C++). Your results may vary, especially because I don't know how the Java factor will play out. My approach is threefold: First, filter out obvious answers. This includes negative nu...

What is state-of-the-art for text rendering in OpenGL as of version 4.1? [closed]

...GPU, but it is much easier and more efficient to that kind of thing on the CPU, as it is a strictly sequential operation and not at all trivial (think of kerning). Also, it would need another feedback pass, which would be another sync point. Render the previously generated data from the feedback buf...

A new option, -fno-aggressive-loop-optimizations, was added to disable this aggressive analysis. In some loops that have known constant number of iterations, but undefined behavior is ...
