AIGLX + beryl 终于跑起来了

比XGL还要顺畅 哦yeah!

A good article about DocBook

reStructuredText

rst可以让你从文本文件生成html/xml/LaTeX http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html http://docutils.sourceforge.net/docs/user/rst/quickref.html http://docutils.sourceforge.net/docs/user/rst/quickstart.html

还是screen

C-o会和vim里的命令冲突的 所以现在用\\ escape \\\\ 意思是\是命令键,相当于之前的C-a,要打反斜线\就打两个\\ 同理 escape ^Oo 意思是C-o是命令键,C-o o就相当于C-o

看来我应该放弃AIGLX的努力了

https://help.ubuntu.com/community/CompositeManager/AIGLX Information about unsupported hardware The open-source ATI driver (radeon) uses software rendering for alpha (transparency). This makes Compiz unusably slow on a Radeon 9200 (one of the fastest cards supported). No word from ATI on when their proprietary driver (which has proper 3d acceleration) will support AIGLX.

想让screen更像个桌面么?

需要有个好的screenrc screen的默认配置的最大问题是ctrl-A和bash里回到行首的快捷键冲突,导致要使用后者要多打一个a(ctrl-a a)。比较麻烦。 下面这个screenrc重定义了这个快捷键 而且加上了一个更漂亮的caption,有日期时间主机名等 现在terminal是否有tab功能对我来说已经无所谓了 哈哈 # ~/.screenrc # use visual bell vbell on # replace ctrl-A by ctrl-O escape ^Oo # set a big scrolling buffer defscrollback 5000 # Set the caption on the bottom line caption always "%{= kw}%-w%{= BW}%n %t%{-}%+w %-= @%H - %LD %d %LM - %c"

一个python脚本,把一个目录下所有文件转成utf8编码

chardet package is in gentoo-china-overlay layman -a gentoo-china I have already filed a chardet's bug, requesting it to be added to portage However, no response yet #! /usr/bin/python import sys,chardet,shutil,os,tempfile def convert(fname):         fp = open(fname)         text = fp.read()         encoding = chardet.detect(text)['encoding']         rate = chardet.detect(text)['confidence']         if rate > 0.9 and not encoding == 'utf-8':                 tmp,tmpname=tempfile.mkstemp()                 os.write(tmp, unicode(text,encoding).encode('utf-8'))                 shutil.move(tmpname, fname) if __name__=="__main__":         dir = sys.argv[1]         for f in os.listdir(dir):                 pathname = os.path.join(dir, f)                 convert(pathname)

gdb里调试信号处理函数

要执行handle signum nostop 这样在收到信号的时候gdb就不会暂停执行 对于SIGINT,还需要 handle SIGINT pass 这样SIGINT信号就不会被gdb所截住,而是发给正在debug中的程序

Videos of SHLUG's talk on 9.10 is releasing!

http://www.shlug.org/ There were 3 talks on that day. One of them is about Godson. A Godson's real machine was shown during the talk.

Emacs + Gdb

早有耳闻这两者是不错的搭配 真正试验了一把之后发现 那岂止是不错,那是相当的不错! 绝配啊 Linux的程序员一定要试一下 否则终生遗憾 两个提示: 一个是在~/.emacs里定义变量gdb-many-windows:(defvar gdb-many-windows t) 再一个是启用gub-tooltip-mode,这样鼠标指向源代码里的变量时,emacs就能以tooltip提示框的形式显示变量的地址和值。再也不用p和x了。 简直是太方便了,太方便了!

gdb in emacs, gdbtui and inputrc

In readline, C-j functions like "enter" key. However, I defined C-j as menu-complete in my ~/.inputrc. So, in gdbtui and when using gdb in emacs, enter key don't function as usual, instead it performs menu-complete. As a consequence, i can't use gdbtui and gdb in emacs. I solved the problem myself. I just thought that this problem should has something to do with readline library. Maybe my readline is too new? This is my first suspicion. Then I suddenly remembered that I had redefined some key-binding in my ~/.inputrc. Thus, the problem solved. reference: http://tiswww.tis.case.edu/~chet/readline/rltop.html

gdb在c++程序里设置断点

原来需要写出完整的函数名,从namespace开始 比如ost::ScriptCommand::getMember 不需要用mangle过的名字 有时候可能需要执行 set language c++ reference: http://sources.redhat.com/ml/gdb/2005-07/msg00066.html

mozilla-launcher支持aoss了

这样看youtube就不必再手工用aoss firefox来启动了。 还有audacious支持id3 tag的编码侦测了,这是Liu Qing提供的消息。 http://gentoogle.blogspot.com/2006/09/emerge-audacious-112.html
