Getting Sun JDK 6 on a Strato V-Server with Ubuntu 8.04 LTS

admin — Sun, 01 Nov 2009 21:28:48 +0000

I installed Java 6 on a Strato V-Server today that a default installation of Ubuntu 8.04 LTS.
Per default, the multiverse packages are all disabled, so you need to edit the file /etc/apt/sources.list to make it look like this:

# See sources.list(5) for more information, especialy
# Remember that you can only use http, ftp or file URIs
# CDROMs are managed through the apt-cdrom tool.

deb ftp://ftp.stratoserver.net/pub/linux/ubuntu hardy main restricted universe multiverse
deb-src ftp://ftp.stratoserver.net/pub/linux/ubuntu hardy main restricted universe multiverse

deb ftp://ftp.stratoserver.net/pub/linux/ubuntu hardy-updates main restricted universe multiverse
deb-src ftp://ftp.stratoserver.net/pub/linux/ubuntu hardy-updates main restricted universe multiverse

deb ftp://ftp.stratoserver.net/pub/linux/ubuntu hardy-security main restricted universe multiverse

deb-src ftp://ftp.stratoserver.net/pub/linux/ubuntu hardy-security main restricted universe multiverse

Then don’t forget to run

sudo apt-get update
sudo apt-get upgrade

Setting up an Ogre3D Project in Code::Blocks IDE on Ubuntu

admin — Mon, 22 Jun 2009 00:26:31 +0000

These steps are for ubuntu users. the paths may differ for other linux distributions but i think the steps are the same.

Be sure to have installed Ogre3D and code::blocks on ubuntu before you proceed. The ogre3d wiki is a good start if you search for installation how-to’s.

Step 1:

Open Code::Blocks and create an ogre3D project with the wizard.

Step2:

After creation right click the project in your workspace and choose the “Project Build Options“.

Go to the “Linker Settings” tab and change the libOIS and libOgre paths according to my screenshot:

Step 3:

Goto the “Search directories” tab and in the “compiler” subtab add the path to the ExampleApplication.h file.

in my case it’s

/home/myuser/Development/lib/ogre/Samples/Common/include

You should be able to compile your project now. )

Step 4:

Now we need to make sure, that the the run command also works on our small project.

Therefore we need to change the execution path of our project’s binary.

This can be done by right-clicking the project in the workspace again but this time select the “Properties…” option.

Switch to the “Build targets” tab and alter the parameter for “Execution output dir:” to your ogre3d installations sample folder.

In my case this is

/home/myuser/Development/lib/ogre/Samples/Common/bin

Now you can run the project.

That’s it. Happy coding.

So you also have a problem with the menu font size in Mathematica 7.0?

The solution for KDE 4 users is fairly simple:
You may not have set the correct DPI for your system.

In KDE this is done in the Apearance tab in the System Settings.
Goto Fonts and there will be the drop down for Force Fonts DPI.

Set it to 96 DPI and restart Mathematica. That’s it.

Forcing 96 DPI in KDE control center.

Yes, it is possible and it’s not that hard as you may think:

sudo apt-get remove cabextract
sudo apt-get install cabextract
./ies4linux

try running this command that actually worked for me:

./ies4linux –no-gui

Update GRUB MBR settings after VISTA or XP reinstallation

admin — Wed, 13 Aug 2008 09:07:34 +0000

I trashed my vista installation on my dual boot system this weekend. As we all know, vista is quite keen on controlling the Master Boot Record (BMR) .

All my tries to use update-grub failed.
After yahooing for a while I found the Super Grub Disk – a stand-alone bootable CD-Rom Image that leads you through grub update (and many other grub related tasks) with easy menus and online help.

It took me 3 minutes to get my grub installation working again.

Unable to open device "hal:///org/freedesktop/Hal/devices/usb_device_*": Permission denied

admin — Sun, 01 Jun 2008 21:37:07 +0000

My Brother-2030 printer denied printing for the last month and I couldn’t find redemption.

The IPP report message was:
Unable to open device "hal:///org/freedesktop/Hal/devices/usb_device_": Permission denied

But I figured it out. The final solution is easy:

sudo chmod 700 /usr/lib/cups/backend/usb
sudo chmod 700 /usr/lib/cups/backend/hal

I post this, because I’m not the only one having these kind of problems with HAL and a USB printer while using ubuntu (with 64 bit architecture).
Maybe this will help someone searching for a solution.

UDATE:
I updated the command with Jim Morris’ comment.
