OS

What OS stands for? The question occurred to me when I viewed Coolnicsky's blog (Long time no update!). I knew OS meant "旁白、独白" in Chinese but I never thougut about where the abbreviation came from. As people saying "Acknowlege what is known as known, and GOOGLE what is not!", I G it and the answer is "Off Screen", not what I guessed like Outside Sound or Oral XXX...

OS also means Operating System such as Windows, Linux, Mac OS...

Linus vs C++

大牛Linus在骂C++,这人脾气也太火爆了...如此看来回去把C++仍了吧...
我觉得C++ STL挺好用的啊...OK, I am a substandard programmer...

*YOU* are full of bullshit.

C++ is a horrible language. It's made more horrible by the fact that a lot
of substandard programmers use it, to the point where it's much much
easier to generate total and utter crap with it. Quite frankly, even if
the choice of C were to do *nothing* but keep the C++ programmers out,
that in itself would be a huge reason to use C.

Calm down

AH~~~~~~~~~~~~
I regret not preparing TOEFL early, 5555...

It seems many Canadian Universities provide Msc programs with scholarship and no GRE requirment, but my pity oral part score cannot fulfill any!!! :sad: Now that the only I can say is TAKE IT EASY, EASY AND EASY.

p.s. I installed Ubuntu 7.10, a new version. It's much more stable than I considered. I'm trying to drop XP and move to Linux, facing the biggest problem --QQ. Tencent doesn't release any Linux version of QQ and changes the protocol frequently so as to prevent others' development on QQ client. Narrow-minded!

继续忙碌中

忙完整整3天的数模比赛,我已近乎崩溃,3天睡10小时,到最后只看到同学张嘴就是不能反应他在说什么了。

Bless我们的论文,说起来内容也很拗口,股指的事件窗口影响模型、指数预测的SVM和线性趋势衰减模型,胡乱拼凑了一番,到最后不得不承认对股票的预测方法和扯淡区别不大,如果能和直接用前一天收盘价预测一样,已经谢天谢地了,弄不好就给你来一个一天跌1000点-__-

现在忙于数字信号处理、Linux程序设计、自动控制三座大山的期末大作业,bless自己,bless人的能力无限,over。

3D桌面

还记得《少数派报告》里面确认罪犯的那个超酷的三维系统么?

还是忍不住冒着崩溃的危险在新的Ubuntu下面装了Beryl的Xgl桌面。上次装Aiglx+Beryl的时候系统就彻底崩溃了,还好这次的Xgl没有~

装上后发现X-window变得超级!@#$%^&*,半透明、阴影、前后遮挡、扭曲、渐变、贴在立方体上的四个旋转桌面,甚至还有超炫的水波特效。不过还好,x1400的显卡还算跑得顺畅。不过除了好玩还真是没什么用处......

World Coded

看Linux的内核代码分析,偶然看到Linus的一句话:RTFSC--Read the f**king source code.

然后发现身后的同学在看Matrix...忽然又幻想世界也许就是代码的,如果我们看到源代码,就可以做上帝的事情...

然后就想到模式识别课的非线性多层神经网络和反向传递算法,是不是模型和代码真的可以模拟任何东西呢?

疯了疯了,代码开始占据我生活的每个角落......

怀抱Linux

忍不住好奇心的驱使,装上了Ubuntu(Linux的一种版本),其实大家知道的一般是Redhat吧,不过Ubuntu最近很火啊,可能是比较容易上手的关系。

我算是彻彻底底的Linux新手,所以亦步亦趋的跟着网上的指导做,不时备份程序以防不测。现在终于几乎搞定了内核、驱动、常用软件等东西,中间系统崩溃过几次,还好通过我以前的备份、可怜的几条Linux命令,都恢复过来。

Linux的系统机制,自由开源的理念精神,很多要学习的东西。越来越发现,自己对本专业兴趣在降低(甚至有些失望),对计算机软件方面倒是兴趣很大:(

毅然退掉了专业推荐选修《数据库》,去选了计算机的必修《操作系统》,我想我知道我喜欢什么,要做什么。

sigh,可是该死的基金导师又忽然拦下院里教改讨论的事情,让我们在三两天内搞出个网上讨论的系统......这其实和我们研究的方向还是有不小差别的,他也说的很清楚,只要系统能够work,让领导方便、开心,目的就达到了,具体如何弄的不重要。就连基金课题的导向,也是领导满意第一,这样什么优秀论文就都有了。原来,就连PKU也不过是官僚笼罩下的一个类科研机器而已,国内的研究状况可见一斑。

回到Linux,看到的是一种大气。(似乎跳跃比较大-__-///)
