First round of this book has just been finished. It is a wonderful book. It focuses on teaching readers how to analyze & solve problems, including typical CS algorithm problems and also some interesting Maths problems. But actually I am not interested in

<br />I TOTALLY skipped Maths part of CLRS in this 2nd round. You know what, I can finish nearly 100 pages per day, for the first 200 pages of this book. (Practice Problem not included of course... I guess I will tackle them in the 3rd round)<br /> <br />I

C语言测试是招聘嵌入式系统程序员过程中必须而且有效的方法。这些年，我既参加也组织了许多这种测试，在这过程中我意识到这些测试能为带面试者和被面试者提供许多有用信息，此外，撇开面试的压力不谈，这种测试也是相当有趣的。    从被面试者的角度来讲，你能了解许多关于出题者或监考者的情况。这个测试只是出题者为显示其对ANSI标准细节的知识而不是技术技巧而设计吗？这个愚蠢的问题吗？如要你答出某个字符的AS

作者： 黄镭  程序员需要知道什么？　　作为程序员必须掌握的最基础的知识是什么？在做了十几年程序员后回头看这个问题，我发现最基础的知识既不是某种语言的语法，也不是算法。而是计算机的工作原理。因为程序员的工作是指挥计算机按照他（她）的想法干活。不了解计算机的脾气是无法有效的指挥的。计算机非常"笨"而且"懒"，必须使用排列好的指令序列（程序）去"踢"它，"踢"一下它才动一下，不小心把它"踢"进了死胡同

As a CS lover, I guess you must have read CLRS, maybe 2nd version, or even 3rd version. Unless you are a Math fan, you may find it too theoretical, and probably you were abashed by its tons of Math details. I think CLRS is mainly for ones who intend to dev

According to http://www.youtube.com/watch?v=e6mTwgZuV50, the most significant update in CLRS 3rd is the introduction of Parallel Algorithm (Chapter 27). There’s a free e-doc version of this chapter from Intel : http://software.intel.com/sites/products/docu

Finally Turing machine is introduced. With NFA\PDA in mind, readers should be able to understand Turing machine without too much effort. Again, Prof. Michael Sisper deserves a title of Teaching Guru.

一般认为在c中分为这几个存储区 1栈 - 有编译器自动分配释放 2堆 - 一般由程序员分配释放，若程序员不释放，程序结束时可能由OS回收 3全局区（静态区），全局变量和静态变量的存储是放在一块的，初始化的全局变量和静 态变量在一块区域，未初始化的全局变量和未初始化的静态变量在相邻的另一块区域。 - 程序结束释放 4另外还有一个专门放常量的地方。 - 程序结束释放 在函数体中定义的变量通常是在栈上，

老大讲没有经验的工程师经常会掉到细节的陷阱里去从而无法从大局角度去考虑一个系统。反观自己和新来的几个intern，还真的是这样，包括原来在俱乐部做设计讨论的时候，大家也常常掉到一些细节里面，比如在考虑一个大的系统的时候，思路常常会转到某个技术细节到底该怎么实现的陷阱里。

回来这几天主要在重新阅读《自己动手写操作系统》 ，有了8个月的实习经验再来看这个就要驾轻就熟得很多。很快的浏览了这本书里讲的关于保护模式、保护模式下的中断处理章节，有了一个很清晰的感性认识，基本扫除了对保护模式的心理障碍。感觉x86保护模式基本就是在GDT IDT cr3(pdbr)三个表的控制下进行。还有一个最关键的技术没有理解透彻：多进程切换时的堆栈切换，包括tss。《自》这本书写的的确好，唯

终于有"后"了,呵呵~ 2号拿到书,3号开始看,到今天看完,整整一个礼拜 .总的来讲这本书还是绝对经典的,分别对语言细节和设计两个方面进行了恰到好处的讲解.不过感觉还没有足够深入,可能就是因为这个Meyes又写了More一书
