HTTP vs HTTPS performance
...
The overhead is NOT due to the encryption. On a modern CPU, the encryption required by SSL is trivial.
The overhead is due to the SSL handshakes, which are lengthy and drastically increase the number of round-trips required for a HTTPS session over a HTTP one.

What is the list of possible values for navigator.platform as of today? [closed]
...his definition is a bit vague. A decade ago a 'platform' would either be a CPU architecture or an operating system. In recent years handheld and media devices can be platforms too.
The interpretation
As with everything on the web, our fate is in the hands of the mighty browser vendors. In this case...
Encapsulation vs Abstraction?
...f you go down all the way to the raw silicon, the people who designed your CPU did so using circuit diagrams written in terms of "diodes" and "transistors", which are abstractions of how electrons travel through semiconductor crystals.
In software, everything is an abstraction. We build programs wh...
Are non-synchronised static methods thread safe if they don't modify static class variables?
... technically the method is to be inlined and the parameters will be CPU registers. Nonetheless the answer is correct

How does this milw0rm heap spraying exploit work?
...e chunk, the probability of jumping there is high). When we jump there the CPU will keep executing or cl, [edx] instructions until in reaches the beginning of shellcode that's put in memory.
I've disassembled the shellcode:

...worse code in the other. I think you'd either optimize this for a specific CPU or leave it as it is and let the compiler to choose what it thinks it's better.

How do you create an asynchronous method in C#?
...Seconds(1));
}
return DateTime.Now;
}
If your async method is doing CPU work, you should use Task.Run:
private static async Task<DateTime> CountToAsync(int num = 10)
{
await Task.Run(() => ...);
return DateTime.Now;
}
You may find my async/await intro helpful.

What is the fastest/most efficient way to find the highest set bit (msb) in an integer in C?
...intrinsics like ARM GCC's __clz (no header needed), or x86's _lzcnt_u32 on CPUs that support the lzcnt instruction. (Beware that lzcnt decodes as bsr on older CPUs instead of faulting, which gives 31-lzcnt for non-zero inputs.)
There's unfortunately no way to portably take advantage of the various...

What is the memory consumption of an object in Java?
... memory alignment done by a particular JVM implementation for a particular CPU type. It looks like a Long is 8 bytes of Object overhead, plus 8 bytes more for the actual long value. In contrast, Integer had an unused 4-byte hole, most likely because the JVM I use forces object alignment on an 8-byte...
