ubuntu-12.04

I'm running that configuration : Ubuntu 12.04 Intel HD Graphics 4000 glxinfo give me that parameters: OpenGL renderer string: Mesa X11 OpenGL version string: 2.1 Mesa 8.0.4 OpenGL shading language version string: 1.20 OpenGL extensions: My goal was to run OpenGL 3.3 (and so GLSL 3.3). If I'm easy with development issues, I'm lost in hardware and drivers, so does someone knows a way to achieve that with my configuration? Unfortunally at this moment it looks like this is not possible, since the open source drivers provided by Intel are the only available. There is a version newer than yours

I am trying to run the JUnit on my Linux command prompt /opt/junit/ contains the necessary JARS(hamcrest-core-1.3.jar and junit.jar) and class files and I am using the following command to run the JUnit: java -cp hamcrest-core-1.3.jar:junit.jar:. org.junit.runner.JUnitCore TestRunner TestJunit class: import org.junit.Test; import static org.junit.Assert.assertEquals; public class TestJunit { @Test public void testAdd() { String str= "Junit is working fine"; assertEquals("Junit is working fine",str); } } TestRunner: import org.junit.runner.JUnitCore; import org.junit.runner.Result; import org

I have a VirtualBox machine running Ubuntu 12.04 in a Mac OS X host machine. In my host machine (Mac OS X), I have PostgreSQL installed. I would like to connect to this PostgreSQL server from my Ubuntu virtual machine (I know normally it's the opposite way). I guess I should configure some networking parameters in VirtualBox itself. All I get from Vagrant docs is I need to assign my vm a static IP to use a private network. But once created, how do I reach my host from my guest? I didn't find anything like that in vagrant docs. So, there's probably a good reason for that. Does it make sense? I

I am very new to python.I installed an openflow controller on my Linux PC (Ubunutu 12.04) called RYU using: sudo pip install ryu I was trying to run a python file using ryu-manager as shown below. sudo ryu-manager simple_switch.py Traceback (most recent call last): File "/usr/local/bin/ryu-manager", line 19, in <module> import gevent ImportError: No module named gevent Then I tried to install gevent using: sudo pip install gevent gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -I/usr/include/python2.7 -c gevent/core.c -o build/temp.linux-x86_64-2.7

I have installed cron via apt-get install cron Trying to start cron fails (as expected) because of upstart not running. What is the command line for starting cron properly (i.e. it will read users' crontabs, will read /etc/crontab/* etc)? Please note that I do not want to start the container as a "full" machine, so I don't want to run /sbin/init or upstart . I manage the processes via supervisord , so what I 'm missing is the command line to add to its configuration file. You can run cron without daemon mode. root@xxxxxx:~# cron -f I was just trying to test it: I started /bin/bash in a new
