1. Cross-compiling issues on uClibc;
2. Porting Linux applications from glibc to uClibc.
A few causes of segmentation fault can be summarized as follows, attempt to execute a program that does not compile correctly. Note that most compilers will not output a binary given a compile-time error.buffer overrunsusing uninitialized pointersdereferen
转眼间已闲置约70天,当初退出那份工作的勇气,已经成为回忆。无论如何,我坚信自己的选择是正确的,现在需要的是准备,为新的机会。
三年间一直从事所谓研究工作,其实也就是预研工作,主要是软件原型产品开发方面。这是一个基本能接触到软件生命周期所有过程的机会,也是一个能自我发现的工作。因为工作机会,总是能够接触一些设计、代码优化的工作。在Google的帮助下,有着众多网友的推荐,我觊觎某个机会一睹大师手笔。Programming Pearls,Design Patterns(GoF),代码经验与设计
Problem: You are given an array of n integers. All the integers occur even number of times except one. Find this integer with O(n) time and O(1) additional space. Solution: Due to the time and space required, it's not poss
路人母亲:“你为什么把苹果丢掉?”
路人小孩:“因为苹果烂了。”
路人母亲:“烂的,你可以把它(烂掉的部分)切掉,它还是一个好苹果嘛。你把它丢掉就没有了!”
符老师:“你看,丢掉,就完了。”

题:x>0,y>0,且x+2y=1,求u=1/x+1/y的最小值。
俺们号称还是学过高数的,x用y表示后,立即求y,使得取u'=0,叭啦叭啦一堆算式得u最小值。好累!
可是我家领导说既然x+2y=1,那么u=3+(2y/x+x/y),中学数学内容!没办法,我家领导是专业人士,服!
