如果head tracking能够应用于游戏之中，那种现场感就真的太令人震撼了。想象一下，CS里面一颗一颗呼啸而来的流弹，极品中车窗外的景色，一切都会随着你的头部的移动而相应变化。此时此刻，小小的屏幕，真的成为了看世界的一面窗户。

这是slashdot上面的一篇奇文，与君共享之

There is a sad truth to the world today. I am part of a dying breed of people known as "shell users." We are an old-fashioned bunch, preferring the warm glow of a green screen full of text over the cold blockiness of a graphical interface. We use ssh, scp, and even occassionally ftp. Back in the days before high-speed connections ("broadband"), we would dial up during off-hours to avoid being slammed with huge phone bills. The whole "Microsoft Windows" fad will fade away sooner or later, but in the interim, our kind is facing extinction.

Because there are fewer and fewer of us, I must help keep our lineage alive. I am looking for someone to help me do this. I need a woman (obviously) who is willing to raise a child with me in the method of Unix. Our child will be introduced to computers at a young age, and will be setting emacs mode before any other child can even read. I earn a sufficient income to support a family in modest comfort. Other than the fact our child will be bright, text-based and sarcastic, we will otherwise be a normal family. We will even go to Disney World and see Mickey Mouse.

So, if you are a woman between the ages of 23 and 43 who is ready to raise a child in the way of the shell, let me know so we can begin the process. (If you are ready to raise more than one child, even better.)

PS - yes, this is for real. Given the right person, I would obviously propose before we ... call fork().
PPS - I only set emacs mode for my ksh session. I only edit files using vi. Just wanted to clear that up. And I'm looking to raise the child(ren) as a dedicated couple, so if you aren't interested in being married, you may wish to select() a different posting.

N.B. - on the issue of relocation. I live in a place where my income/expense ratio is proper (i.e., greater than 2:1). I'm willing to live anywhere in the world where this remains true. I've been to much of the country as well as foreign nations. There are no limits to where I will live *so long as the job market for unix admins is robust enough to be sustainable.* And yes, I am interested in a strictly monogamous situation. I've been known to actually turn down offers of "two chicks at the same time."

作为一个技术为主的blog，大量的代码肯定是有的。但是这个iblog默认对代码没有什么支持。贴代码不是很方便，而且贴出来的代码也是和其他的文字没有啥区别。

但是我们可以发现其他的很多blog都可以高亮显示代码的，看起来还是很漂亮的。那么如何在iblog里面是代码也可以五颜六色呢？

命令历史（history命令，或~/.bash_history文件）的功能主要是使用户避免重复输入很长的命令。但是每个铜板都有两面，命令历史由于是明文保存，所以如何你在bash的命令行中输入了一些特殊的重要的信息，那么这些信息就很可能被其他人轻而易举的获取。

命令历史的另外的一个问题是，我们使用频率最高的命令并不是我们最希望保存下来的命令。什么命令使用频率最高？无非是ls, cd, who, ps等等。保存这些命令一点价值都没有。占用一些磁盘空间倒是小事，他们会把我们真正想要保持的命令挤出.bash_history文件才是大事。

那么，如何是好？ 

虽然18m的春节晚会不算质量上乘，但是好在中了个三等奖，了胜于无，也算不虚此行。
