mysql.m compile 64 bit ubuntu linux

So I downloaded the awesome file exchange mysql.cpp file to link Matlab.

http://www.mathworks.com/matlabcentral/fileexchange/8663-mysql-database-connector

Then I installed the mysql and the extra libraries I thought I needed.

Then in Matlab I ran:

mex -I/usr/include/mysql -L/usr/lib/mysql -lmysqlclient mysql.cpp

and I got this error:

Warning: You are using gcc version "4.5.2-8ubuntu4)". The version
currently supported with MEX is "4.3.4".

mex: compile of ' "mysql.cpp"' failed.

After digging around on the Internet I finally found the solution, and it was very simple:

Navigate to here:

$MATLAB_ROOT/sys/os/glnxa64/

(first make a backup of that folder just in case). and run these two commands:

mv libstdc++.so.6 libstdc++.so.6.orig
mv libgcc_s.so.1 libgcc_s.so.1.orig

Then I didn't even need to restart my Matlab session, I just reran the mex compile command it it worked! Yay!

How to 3 monitors 2 graphics cards ubuntu xorg.conf

Important points:
Make sure binary drivers are installed for your graphics cards.
Use nvidia-settings to create and test your xorg.conf files. I noticed it was a lot easier to start with one screen, get each one working individually and then combine.

Backup, backup, backup your working xorg.conf. I screwed this up >10xs and it was nice to have a backup. Also alt-ctrl-backspace came in very handy so I could quickly retest my xorg.conf by restarting.

Option "Xinerama" "1" was needed so I could pass windows between my screens. I had issues using this if compiz effects were enabled, so I just turned off all, looks like it is an issue specific to 11.04, not older versions.

Also lspci |grep VGA was helpful to see my card info, this was needed in the xorg.conf file. I had issues with the relative screen positioning so I used absolute positioning which I would recommend.

Please post comments with any questions or feedback.

Ubuntu Mint Install Nividia GTX 480 Drivers

First I went to the Nividia website:

http://www.nvidia.com/object/linux-display-amd64-285.05.09-driver.html

And found the right driver for my system. Downloaded the ./NVIDIA-Linux-x86_64-285.05.09.run file.
Change the permissions so I could execute:

chmod 777 ./NVIDIA-Linux-x86_64-285.05.09.run
Then I executed it:
./NVIDIA-Linux-x86_64-285.05.09.run

But it gives me a warning and says I have to kill my xserver. I Do this (I am using gnome):
sudo /etc/init.d/gdm stop

After I kill it I run the same command I tried above and follow the directions and it worked fine.

"You have not chosen to rust "Entrust.net"" ubuntu ica fix

So I installed the new citrix ica client so I could remote into work on my ubuntu netbook but I get this error when trying to open up the application:

"You have not chosen to rust "Entrust.net"... blah blah blah SSL error...

To fix this you need to copy the Entrust.net certificates to your ICAClient/keysyore/cacerts/ directory.

Mine was located here:
/usr/lib/ICAClient/keystore/cacerts/

To get the Entrust.net certificates you can download them directly here:
wget https://www.entrust.net/downloads/binary/entrust_ssl_ca.cer

Or go to the www.entrust.net/downloads and find the root certificates. Then answer a few stupid questions and download it.

Once you downloaded it you have to change the file extension from .cer to .crt. Once you have copied that file into the folder above you are DONE! I didn't have to close my browser or even login again, I just clicked on the application and it worked perfectly!

ubuntu how to copy all file types to a single folder

So I wanted to figure out an easy way to search my computer and my servers for a specific file type, in my case .eps figure files and copy them all to a single folder for me to review.

So first I need to make a folder to copy them do so I did this:

First I made the directory
mkdir figall

Move to the root folder
cd /

Now copy all files with extension .eps to my folder
sudo find -name "*.eps" -exec cp \{\} ~/Desktop/figall/ \;

Now I could repeat this for any file extension:
sudo find -name "*.jpg" -exec cp \{\} ~/Desktop/jpgall/ \;
sudo find -name "*.doc" -exec cp \{\} ~/Desktop/docall/ \;
sudo find -name "*.tex" -exec cp \{\} ~/Desktop/texall/ \;

make ubuntu gnome look like windows XP

This was great, I downloaded it and within minutes my entire desktop looked just like windows. Don't get me wrong, I hate windows and I can't wait for it to go out of business but this is funny and now people that use my computer will be clueless that it is not windows.

http://ubuntu.online02.com/node/14

Here is the direct link:
http://ubuntu.online02.com/files/XpGnome.tar.gz

Just:

tar -xvf XpGnome.tar.gz
cd XpGnome
sudo ./InstallXpGnome.sh
