What is the difference between synchronous and asynchronous programming (in node.js)
...output the same thing as #1? Like for instance, database.query finishes so fast that by the time we reach console.log the task is already done.

HTTP vs HTTPS performance
...een http and https? I seem to recall reading that HTTPS can be a fifth as fast as HTTP. Is this valid with the current generation webservers/browsers? If so, are there any whitepapers to support it?

..., "I know it when I see it." The same holds here.
I hate making hard and fast rules like this because the answer changes not only depending on the size and scope of your project, but I think it changes even down to the module level. Depending on what your method is doing, or what the class is sup...
Why do you program in assembly? [closed]
...ler output by the compiler to figure out exactly what to optimize.
Quake's fast inverse square root. Again, the routine doesn't have assembler in it, but you need to know something about architecture to do this kind of optimization. The authors know what operations are fast (multiply, shift) and w...

Why is it faster to check if dictionary contains the key, rather than catch the exception in case it
...and, accessing a value in a dictionary by its key is cheap, because it's a fast, O(1) operation.
BTW: The correct way to do this is to use TryGetValue
obj item;
if(!dict.TryGetValue(name, out item))
return null;
return item;
This accesses the dictionary only once instead of twice.

To edit them
Using code:
ASM: Visitors based, very, very fast.
BCEL: Loads the bytecode as an in memory description of the class file.
Javassit: the easiest one to use, allows you to do pattern matching and expression replacement.
By hand: JBE
