Calling Chrome web browser from the webbrowser.get() in Python

How I should call webbrowser.get() function so I open the chrome web browser? I'm running Ubuntu 11.04 and Python version 2.7. Using webbrowser.get('chrome') yields an error. The quick workaround is to make Chrome the default browser in your system and then use simply webbrowser.get(). I've just checked that on ubuntu 10.10 and it worked just fine. EDIT Just reviewed the code of /usr/lib/python2.6/webbrowser.py. You should do like this: In [5]: webbrowser.get('/usr/bin/google-chrome %s').open('http://google.com') Created new window in existing browser session. Out[5]: True In [6]: webbrowser

问题 I am trying to edit sources.list using vi editor but getting the following error while saving the file: /etc/apt/sources.list" E212: Can't open file for writing 回答1: For some reason the file you are writing to cannot be created or overwritten. The reason could be that you do not have permission to write in the directory or the file name is not valid. Vim has a builtin help system. I just quoted what it says to :h E212 .

How to enable global menu bar for Emacs on Ubuntu (Unity 11.04)

I use latest Ubuntu 11.04 which has Unity desktop. I am learning to use Emacs 23. As you know, Unity has top panel. I want to enable global menu bar for Emacs so that I could save valuable screen space. (I use small screen laptop) How to enable global menu bar? Your help will be much appreciated. Thank you. appmenu-gtk (which provides the global menu bar) specifically blacklisted emacs since it does not play nicely together so unfortunately you probably can't use it with emacs. Use your favorite editor to open this file: /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so Find the word "emacs"

I installed APC on my ubuntu 11.04 linux and I want to make some performance benchmarks to see what's the speed improvement over PHP without APC but I don't know how to disable/remove the APC. I tried to empty my apc.ini files but it didn't worked. Still after I load a page for the first time, the page will be stored in the cached and the second time I load the page, it loads much faster. Here's a PHP file that I use to measure the time. <?php function getTime() { $a = explode (' ',microtime()); return(double) $a[0] + $a[1]; } $Start = getTime(); ?> <?php require_once("includes/connection.php"

问题 How can i extend default lib search path in ubuntu(in a way that it is also persistent) ? no, I do not want export LD_LIBRARY_PATH based temporary solution, rather some way to extend the default lib search path ? while google-ing, I cam across some info, that in ubuntu the default search path resides in /etc/ld.so.conf.d , but editing libc.conf does not extended the default path.. so i think either i am doing it wrong, or something is missing... the edited libc.conf looks like... # libc
