ubuntu-12.04

I am rather new to Linux (Ubuntu) and installing (Python) packages. I'm having trouble with mkvirtualenv and can not solve it: ~$ mkvirtualenv mysite70 New python executable in mysite70/bin/python Traceback (most recent call last): File "/usr/lib/python2.7/site.py", line 562, in <module> main() File "/usr/lib/python2.7/site.py", line 544, in main known_paths = addusersitepackages(known_paths) File "/usr/lib/python2.7/site.py", line 271, in addusersitepackages user_site = getusersitepackages() File "/usr/lib/python2.7/site.py", line 246, in getusersitepackages user_base = getuserbase() # this

I need to switch the base URL of my working copy in subversion. According to the manual for 1.7 I should be able to use svn relocate. http://svnbook.red-bean.com/en/1.7/svn.ref.svn.c.relocate.html However, on Ubuntu Linux 12.04 I have version 1.6 which doesn't appear to have the relocate command. Is there a way to accomplish this in subversion 1.6 or by some other method? I found the answer I was looking for. It's just a matter of running svn switch --relocate OLD_URL NEW_URL It looks like on subversion 1.7 you can use the new syntax: svn relocate NEW_URL 来源： https://stackoverflow.com

New to XMonad and loving it so far. I have a fairly vanilla / regular XMonad setup and am having problems with dmenu . When I login and hit mod+p nothing happens. If I then open a terminal and hit xmonad --restart then mod+p , dmenu will be working. There must be something wrong with my xmonad.hs ? I tried a no-customization setup of XMonad and things were working normally (i.e. dmenu was working after login). My questions: Is there something wrong with my xmonad.hs ? Why won't dmenu work unless I xmonad --restart ? Could something fail in xmonad.start that would prevent dmenu from loading

I've installed Eclipse and jdk manually. My JAVA_HOME is set, and I am able to run the java -version and javac -version commands, but when I try to run Eclipse, it shows the following message: A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: /home/$USER/development/eclipse/jre/bin/java java in your current PATH How can I fix this? Distro: Ubuntu 12.0.4 64 bits. Java: java version "1.6.0_45" Java(TM) SE Runtime Environment (build 1.6.0_45-b06) Java HotSpot(TM) 64

I'm using Ubuntu 12.04LTS Desktop to develop a Shopify App (using the shopify_app gem), and I ran into this problem when processing the callback URL. Faraday::Error::ConnectionFailed (Connection reset by peer - SSL_connect) Looking at the shopify-app-discuss group here and here, it seems that the problem is with Ubuntu 12.04 and its OpenSSL. I tried to install the most up-to-date OpenSSL, but nothing. One alternative that I found was to use a different, older OpenSSL, one that RVM provides. $ rvm remove 1.9.3 (or whatever version of ruby you are using) $ rvm pkg install openssl $ rvm install 1
