3. Uninstall VMWare Tools
After a failed installation of VMWare Tools I got following message:

The solution was to run the uninstaller first and run the VMWare setup again:
1. ./vmware-uninstall.pl

You know the problem when you go into your device manager and you find unknown devices with missing drivers. What to do in this case?

Go into your device manager:
Start->Control Panel->Device Manager->Double Click on the unknown device->Details->Hardware-IDs

Lookup the hardware ID’s in the net or on this webpage: www.pcidatabase.com. The first number stands for the vendor and the second is for the device. For example in this case VEN_10DE stands for NVIDIA Corporation and 042f for NVIDIA Quadro NVS 290.

Well I do love dropbox but I don’t like to put sensitive data on it because I simply don’t trust other companies taking care of my security. I use a open source program called truecrypt to encrypt my hard drives, usb sticks etc. and it’s doing a great job. After a little research in the Net I found out you can also use it with dropbox. You might think when you create an encrypted container that with each change in it it would transfer the whole file again. Luckily dropbox just transfers the changes instead of the whole file. But I red on somebodies blog that you need to make a small change in truecrypt.

Deactivate in Truecrypt->Settings->Preferences…->Preserve modification timestamp of file containers

Open Command Console and type:
nslookup
set type=mx

There are long description on the net how you can change the settings on your Iphone over ssh. But I found a much easier solution. Just download and install VoIPover3G. You can find it in Cydia. Another useful application is Backgrounder which makes it possible to keep skype running on the background.

Unfortunately SQL Express 2005/2008 doesn’t come with a Backup Agent. So I searched the net for a couple of solutions to schedule it. There are some good TSQL scripts but a little program which you can run in Windows Task Planer. It is called ExpressMaint and can be downloaded here: Info ExpressMaint

It’s awesome how many games you can find on cydia. Especially the games from id-software. Wolfenstein 3d, doom and quake… who doesn’t remember them? Wolfenstein 3d was one of the first 3d ego shooter.
It is also fun to install super nintendo emulator and then you can play all nintendo games like super mario, megaman, zelda and much more…

The emulator I installed from cydia was called snes4iphone. It is pretty stable and you have mainly two different kind of modes to play. Either you can play in portrait or in landscape mode. If you choose portrait you can see the control buttons and in landscape you can see them as well but they are half transparent.

If you do a google search for SNES Rom files you will find plenty of them. To be able to play them you need to copy it into the /var/mobile/Media/ROMs/SNES/ directory on your iPhone with a SSH connection. If the directory doesn’t exist create it but be careful with the spelling. If you don’t know how to setup an SSH connection search my blog for it.

This tool is great and is exactly what I was looking for. You can find it in Cydia. With the help of this tool you can easily switch on/off 3G/WLAN/SSH etc. It also shows your IP. It took me a while to find out where the program was hidden. To see the settings you need to tap with both fingers on top of the screen where you can see the time and your phone career.

  
My current iPhone Theme

1. Install WinterBoard on Cydia
2. Download a iPhone Theme you like and extract the *.zip or *.rar file somwhere temporary
3. If you have SSH installed get WinSCP (Windows) or for example Transmission (Mac) and connect with to your iPhone
4. Copy the files into /Library/Themes/Your Theme Name
5. Go into Winterboard and refresh
6. Select theme and close Winterboard
7. Done

Note:
If you check your in your theme folder there is a folder called icons. So for each program you have installed you can create a custom icon. You just need to name it the same as the application is called. Simple;-)
