I got tired of looking at the matrix screensaver, it’s always green. I felt like changing the color, but there is no option provided to change the color in the preferences. I downloaded the code and made a simple one character change to make the screensaver blue.

The following is what I did

cd ~/projects
mkdir xscreensaver
cd xscreensaver
sudo apt-get source xscreensaver
sudo apt-get build-dep xscreensaver
cd xscreensaver-5.08/
sudo vim xscreensaver-5.08/hacks/glx/glmatrix.c

I changed g = 0xFF on line 785 to b = 0xFF
save and exit (:wq)

sudo ./configure
sudo make
sudo cp hacks/glx/glmatrix /usr/lib/xscreensaver/glmatrix

Now preview your screensaver to see the results!

If you have Xming installed and are forwarding X11 with putty you may notice that all is well until you need to run a gui application as the root user (after issuing sudo su).

If you just need to run the gui application and don’t require the entire root environment then issuing a sudo app should launch your application in Xming.

However, if you do require the root environment then follow these steps.

sudo su
cat /home/your_username/.Xauthority >> /root/.Xauthority

or you could do this

sudo su
su - your_username -c "xauth list" > X11auth
xauth add $(<X11auth)

I found this solution here: linuxquestions.org

Does your laptop squeal? Is it a nasty high pitch noise that occurs when you are running on battery power.

The solution:

• Download Rightmark CPU Clock Utility: http://cpu.rightmark.org/
• Install it
• Go to the advanced CPU settings and click on the Chipset Button
• Uncheck Enable popdown and popup
• Apply to save
• Be done with it.

If you use python via the command line in Windows vista, you’ll notice that it won’t accept command line arguments if you run a script. For example this won’t work: python myscript.py argument1 argument2 Your python script won’t get the arguments. The fix for Windows Vista is:

1. Get an application called: File Type Doctor
2. Find the .py extension in the application
3. Edit the Open action (add it if it doesn’t exist)
4. Select the right python.exe file for "the application to carry out this action"
5. put this in for the command line arguments (extactly as show, with the quotations): "%1" %*

Problem
I want to mount my folders from my webhost over sftp (ssh) on my Windows machine for free. Something like sshfs for Windows.

Discussion
Currently there is no single application that will let me mount an SFTP connection as a drive. There are however applications such as NetDrive, FTPDrive, etc which will let me mount an FTP connection as a drive. So all that’s left to do is create a FTP to SFTP bridge. What does that do you ask? That creates a FTP proxy to your SFTP connection. It will allow you to send your commands from the FTP server to the SFTP connection. There are two tools that stand out to create the bridge we need. The first is mindTerm, an open source solution written purely in java. The second is Tunnelier by Bitvise. I will be using mindTerm with NetDrive in my solution. If you have success with any other combination feel free to comment about your setup.

Solution

• Tools we will need
  • mindTerm
    • License: Free for personal use
    • download link
  • NetDrive
    • License: Free for non-commercial home use
    • download link

1. Download and extract mindTerm
2. Run mindterm.jar (double click it if you can, otherwise in command prompt type in java -jar mindterm.jar)
3. Type in the host you want to ssh into followed by the username and password
4. In the menu click on Plugins>FTP To SFTP Bridge…
5. Type in 127.0.0.1 for the Listen address
6. Type in  21 for the Listen port
7. Select the Remote system type
8. Click Enable
9. Click Dismiss
10. Next we want to install NetDrive
11. Once netdrive is installed, open it up, and click New Site on the bottom
12. Type in localhost (or whatever you want to call it) for the Site name
13. Type in localhost for the Site IP
14. Type in 21 for the Port
15. Select FTP for the Port
16. Select a Drive letter
17. Check Connect as anonymous
18. Click Save
19. Click Connect
20. Click the X to close the window (will minimize to system tray)

There you have it! A SSH/SFTP connection as a drive in Windows. I have tested it in Windows Vista, however it should work just fine in Windows XP.

I have an old T43 laptop by IBM. Recently I put Ubuntu 8.04 (Hardy) on it and started getting a hissing noise when running on battery power. I found 2 possible solutions:

• add the following to /etc/modprobe.d/options
  • options processor max_cstate=2
• get the linux-server kernel
  • sudo apt-get install linux-server

I didn’t get a chance to try the first option as I already put the linux-server kernel on there. If the first one gives you any luck write a comment and let me know.
