铅笔的好处
|
Thursday, November 27, 2008
这种铅笔在美国很是流行，大家写东西都喜欢拿出一支铅笔，或者挂在耳朵上。相反在国内大家还是用水笔和圆珠笔多些，小学以后大家除了画图都不怎么用铅笔了吧。我个人很喜欢这种铅笔。
- 铅笔的好处在于，写错之后可以擦，于是作业纸和考卷都可以显得干净好多。
- 铅笔的可用性是可观的，只要铅芯没断，总是可以写的，而铅心有没有断是一眼就能看出来的。而圆珠笔水笔之流看着好好的其实却写不出来的情况实在碰到过太多次了。
- 铅笔几乎可以在任何材质上书写。有过这么个笑话/题目，就是关于太空失重的情况下怎么写字？铅笔也。
- 自带橡皮的铅笔还可以省去带橡皮的麻烦。想擦把铅笔倒过来就可以了。橡皮和铅笔共存亡!
- 铅笔触及纸面的压感好，这种反馈让我们可以很容易的控制书写的重轻缓急，这是圆珠笔之流很难做到的。同时，铅笔书写产生的刷刷声也是相当悦耳的。
- 通常情况下铅笔总是长的，并且有棱有角，于是比较好挂在耳朵上且不容易掉落。这种便携性的好处不言而喻。
- 铅笔买回来都要削的。比起用削铅笔刀削出来的铅笔，用小刀削出来的更漂亮。而削铅笔的动作是一种对手指手腕身体协调性小脑等的锻炼，并对未来削苹果生梨之类有着潜在的好处。
python下编译成pyc和pyo

其实很简单
用
用
----------------
ps，其实是为了解决如下问题
gnome-panel里有个music-applet的plugin
exaile的rating scale 是0-5星，而music-applet里是0-8星
将/usr/lib/python2.6/site-packages/musicapplet/plugins/exaile.py里的scale改成0-5
然后用上述方法编译一下，再重新载入music-applet就解决问题了.
用
python -m py_compile exaile.py编译成pyc文件

python -O -m py_compile exaile.py编译成pyo文件

一个叫Dayo的哥们面的，面了有一个小时。小总结一下：
1.Bluetooth耳机相当不争气啊 估计是没用对，用手机接的结果耳机就不管用了，估计是自己没弄好
2.搜索a和b之间的距离，应该想到相遇问题，考虑both-side，可以减少搜索节点数
3.hash table的作用是避免搜索整个list/array

这是怎么做到的呢？
echo -e ‘#define cat(c,d) c##.d \n #define mb(a,b) a##@b \n mb(cat(xiyou,wangcong),cat(gmail,com))’| gcc -E -xc - 2>/dev/null |tail -n 1看看这个语句的输出
xiyou.wangcong@gmail.com
这是怎么做到的呢？
echo -e ‘#define cat(c,d) c##.d \n #define mb(a,b) a##@b \n mb(cat(xiyou,wangcong),cat(gmail,com))’用来生成一段C代码，只有宏定义的C代码。
gcc -E -xc - 2>/dev/null再用gcc进行伪编译(-E)，-xc指定这是c代码。这里当然会出错，用2>/dev/null将出错信息删除
tail -n 1把最后一行输出，这样就是所要的邮件地址了

解决T400在linux下无法待机的问题

这个问题并不是一直存在的，当我从Hardy转战到Arch的时候，突然发现不能suspend了。与其说不能suspend，更准确的说法是成功suspend之后无法唤醒。log一切正常，但屏幕只有黑色的底和一个不能移动的鼠标。若干次试验之后可以确认是xf86-video-intel引起的，但迟迟没有找到解决办法。
今天似乎人品有点爆发，在网上看无关贴的时候看到了这个和这个。一试发现果然可以。

Windows 7 初体验
|
Tuesday, November 04, 2008
尽管是一个GNU和Open Source的爱好者，但同时身为一个新软爱好者，当Windows 7在PDC上颇受好评的时候，看看那台老机，反正闲着也是闲着，就当当小白鼠了。这次试用的版本是M3泄露版，版本号6801，也是网上盛传的pre-Beta。花了一个晚上从迅雷down下来iso刻盘安装，安装过程较xp还是要简单的，没什么多少设置的地方。一番等待之后，Login窗口就出现了，很Vista。
装完之后，可以通过Windows Update来下载驱动，很方便。
评分只有1.0，不过Aero好好的用起来没什么问题。
这就是传说中的SuperBar，给人眼前一亮的感觉。
下面是桌面平铺两个窗口
最大化
注意到有一些新的UI设计，也是从Office 07演化过来的吧
另外mspaint默认是保存为png的，不知道是不是toold了呢
再说说使用的感觉，这个pre-beta版给人的感觉一点也不pre也不beta，还挺稳定的样子。当然UI没有什么改变，延续Vista的式样，个人觉得也挺顺眼。Aero Shake这个版本里没有，挺期待的。Aero Shake是有的，很好玩，不过只是用来玩玩而已，用触摸板晃起来不方便><..据说内核是重写过的，占用的资源相对Vista那可是相当少啊，开机开了Aero也只有400多点M内存，用了半天也就500来M。
装上了Chrome Beta, Firefox 3.1 Beta，整一个白鼠机嘛。
