mac os x 10.6: boot from usb
I always like to play around and I hate CDs etc. That's the reason I took an .iso of the dvd and restored it onto a usb diskdrive and restarted the computer while holding down alt(option) key and selected that usb disk.
everything is fine. mac os is now even better than before and the price is more than right. The best feature is the dock and gallery view with scrolling and folder traversing.
BTW: The .iso must be on a mac formated disk, mounted (by double clicking) and then using the disk utility can be restored to the usb disk. But you'll have to drag the mounted iso to source and select the usb disk. somehow I always forget to do that and it takes a few minutes until I realize I need to do it this way.
Have fun.

Excel remove text from the beginning =replace(a1,1,4,"")
Remove the first 4 characters from a string:

result is

result is

excel is bad - trailing characters is worse
I had to copy some text from a table in IE to Excel and then use a concatenate() formula.
But the result contained always a trailing space or so it seamed.
But =trim() or =clean() did not remove it.
Thanks to the online help, I found the following which solved my problem:
=TRIM(SUBSTITUTE(A4,CHAR(160),CHAR(32)))

After a long time I found out:
mod_autoindex is responsible for the generation:
I had to put in the following:
IndexOptions FancyIndexing HTMLTable VersionSort FoldersFirst NameWidth=* SuppressDescription
- Most importantly for me was the NameWidth=*, i.e. automatically size it to the longest name and FoldersFirst so it's like explorer.
IndexStyleSheet "/css/style.css"
- With this I was able to put in a stylesheet and change the font and background
IndexIgnore P*_files components.swf loadflash.js
- This helped to get rid of some files from displaying

Convert vmware machine to virtualbox 3.x
Today I found a nice vmware appliance that was only available as a vmware image. But I dissed vmware server and workstation a long time ago (except fusion) and try to make use of virtualbox.
But virtualbox lacks a lot of things but this is how I was able to move that appliance to virtualbox:
1) the appliance came with the following files:
.nvram
.vmdk
.vmsd
.vmx
.vmxf
2) I started virtualbox and imported the .vmdk
This is really great: Virtualbox can handle .vmdk natively!
3) I opened the .vmx in an editor (for me that means vim) and extracted:
scsi0.virtualDev = "lsilogic"
guestOS = "other26xlinux"
memsize = "512"
4) I created (wizard) a new virtualbox machine using:
Linux, Linux 2.6
512MB ram
use existing harddisk, that's where I choose the disk that I imported in step 2
5) Just for fun I started the machine without changing any settings (like SCSI etc.)
I left all the other settings at default and started the machine, but it crashed:
unkown interrupt or fault at EIP 000000060 c0100295 00000294
and that messages appeared endlessly.
I could not see the previous messages besides uncompressing linux ..... it was too fast.
6) I stopped the machine using HOST+Q then select stop
7) Ok now here come the changes that I should have done before, but I list them here in separate steps.
7.1 Under System -> Processor: check -> Enable PAE/NX
This fixed the unknown interrupt message thing (but the machine would still reboot after the inital steps)
7.2 Under Hard Disks -> Enable Additional Controller->SCSI(Lsilogic)
7.3 and change the attachments-> Slot -> to SCSI Port 0
Now I was able to boot and the system started nicely. But no network!!!
8) vmxnet: Device in slot 0000:00:03.0 is not supported by this driver.
vmxnet: probe of 0000:00:03.0 failed with error -16
Now I immediately new that was bad news and I had to try to get this machine to accept the new network adapter.
The default adapter that virtualbox 3.04 on my machine at least:
PCnet-FAST III (NAT)
I read on a webpage that Intel PRO/1000 MT Desktop would be a better choice.
So I changed it to Network ->Adapter 1-> Adapter Type: Intel PRO/1000 MT Desktop (8254OEM), NAT was ok for me.
9) Still no networking, eth0: error fetching interface information: Device not found
Ok, now I did not really now what kind of distribution it was and I needed to have a look at the network config etc.
9.1) I saw that it was Grub but it looks like it has a timeout=0, because it only displayed the menu very very quickly.
I have not found out how to stop Grub from continuing. Even after 10 times of Host+R
Hitting escape as it was said here did not work:
Occasionally, GRUB requires some simple intervention. Perhaps a new kernel isn’t working correctly with your system or maybe you want to bring the system into a different runlevel than the default. Hit the ESCAPE key to interrupt the GRUB countdown and bring up GRUB’s main menu.
Maybe someone knows how to stop that thing.
9.2) Ok to access the files I used ubuntu-9.04-desktop live iso cd which I added to virtualbox library and then under CD/DVD-ROM -> mount -> iso image file -> ubuntu-9.04-desktop-i386.iso
9.3) I quickly checked the boot order under System->Motherboard->Boot Order and noticed that the default is Floppy-CD/DVD-ROM-HardDisk-Network. That was fine.
10) Live ISO cd running and with ubuntu I just clicked on Places->Home Folder and selected the 4GB Disk it listed. This mounted the hard disk as /media/disk read/write and I did not even have to search for which disk and what parameters to use mount with
11) Using the terminal I checked if there is a configuration like on red hat or on debian but it was not!
12) In /etc/modprobe.conf I found the following statement:
alias eth0 vmxnet
this I changed into
alias eth0 e1000
13) I also changed /boot/grub/menu.lst timeout=30 just so I can enter single user mode
But on that machine I could not just add Single at the end of kernel but had to use init=/bin/bash
Finally, the vmware appliance ran on virtualbox!!!
But virtualbox lacks a lot of things but this is how I was able to move that appliance to virtualbox:
1) the appliance came with the following files:
.nvram
.vmdk

Finally, the vmware appliance ran on virtualbox!!!
Linux - what to do if single user mode does not work
I just been through the problem, where I desperately needed root access to a system and could not boot into single user mode.
It uses grub, but the timeout=0, I was able to mount the harddisk and edit the menu.lst under /boot/grub/menu.lst to timeout=30.
Also I added a second entry and put the word "single" behind the kernel line:
kernel /boot/bzImage rw root=/dev/sda1 Single
but when I booted into the system it just booted into Runlevel 3 as usual.
What I had to do is to add init=/bin/bash to that line and then I was accessing the system again.
Update:
You should run:
sync
reboot
but reboot failed!!
there was a message init: timeout opening/writing control channel /dev/initctl
I had to run reboot -f !!
