I am using an unsigned char to store 8 flags. Each flag represents the corner of a cube. So 00000001 will be corner 1 010001开发者_C百科00 will be corners 3 and 7 etc. My current solution is to &
Is there any (non-mi开发者_如何学Pythoncrooptimization) performance gain by coding float f1 = 200f / 2
Maybe I\'m being misled by my profiler (Netbeans), but I\'m seeing some odd behavior, hoping maybe someone here can help me understand it.
I realize this is way too far into the micro-optimization area, but I am curious to understand why Calls to DateTime.Now and DateTime.UtcNow are so \"expensive\". I have a sample program that runs a c
What is the fastest way of clearing a register (=0) in MIPS assembly? Some examples: xor开发者_如何学编程$t0, $t0, $t0
I am wondering if it is still worth with modern compilers and their optimizations to write some critical code in C instead of C++ to make it faster.
I encountered the following code in JAXMag\'s 开发者_开发知识库Scala special issue: package com.weiglewilczek.gameoflife
In binary search algorithm we have two comparisons: if (开发者_运维问答key == a[mid]) then found;
the project I\'m working on has for each column that needs to be searched a second column called \"ft[columnname]\" which has a FULLTEXT index and only this one is searched against.
I have an array that i use to lookup values. I use the first 2 values to get n rows. for example all rows that have 2 in the first column and 7 in the second.
