Encrypting & Decrypting a String in C# [duplicate]
...tions was 1000, but the parameter is intended to be increased over time as CPU speeds increase. As of 2005 a Kerberos standard recommended 4096 iterations, Apple iOS 3 used 2000, iOS 4 used 10000, while in 2011 LastPass used 5000 iterations for JavaScript clients and 100000 iterations for server-sid...
Android Game Keeps Getting Hacked [closed]
... anything that can be read can also be decompiled, it just a matter of CPU power and stubborness. Obfuscation still lets the code run so while decompiling/deobfuscating the code, the cracker can still compare the running version with the original. It might delay the cracker or stop the less exp...

Lock, mutex, semaphore… what's the difference?
...r of threads to enter, this can be used for example to limit the number of cpu, io or ram intensive tasks running at the same time.
For a more detailed post about the differences between mutex and semaphore read here.
You also have read/write locks that allows either unlimited number of readers or...
What is an uninterruptible process?
... no non-sleeping process, it switches to a "dummy" process which tells the cpu to slow down a bit and sits in a loop — the idle loop).
If a signal is sent to a sleeping process, it has to be woken up before it will return to user space and thus process the pending signal. Here we have the differe...

Is 'switch' faster than 'if'?
...h statement provokes the compiler into sending the value directly into the CPU registers rather than putting it on the stack first. This is therefore in favour of the switch statement and not a balanced test.
Oh and I think you should also reset counter between tests. In fact, you probably should b...
