Here’s how to revert to a previous firmware version on your iPod Touch (iPhone?), even when apple states in it’s release notes for the new (beta) firmware that it’s not possible to revert 
The trick is to correctly enter your iPod into the DFU (Device Firmware Update) mode.
- start iTunes
- connect your iPod to your computer
- press the power button and home button down for at 10 seconds
- release the power button and?keep the home button pressed until iTunes shows a message that it has found an iPod in recovery mode
- option – click on the restore button in iTunes
- select your firmware file (in my case 2.2.1), if you can’t find it, download it here and rename the .zip file into .ipsw, then select it in iTunes
- the firmware update starts, but keep patient! (sometimes it seems nothing happens, but wait, you will see it does)
If you’re lucky to have a monitor calibration gadget (xrite iONE, huey, …) it’s quite easy to calibrate your monitor to see the correct colors. I was wandering how i could use these devices to calibrate my monitors for HD video editing – the question was what white point and what gamma value to choose for this?
Important: I’m trying to setup my monitors to judge colors of video material targeted for LCD/Plasma monitors, not for CRT TVs!
After some research i found the specifications dealing with HDTV:
ITU-R BT.709
EBU – Tech 3299
To put it short, the targets to use in the calibration software are:
White Point: 6500 K (D65)
Gamma: 2.22
I tried to burn both DVD-R DL and DVD+R DL media on my (pre late) 2008 macbook pro with no luck. Toast 9 reported a “Media Error” and i also got an error when i tried it by burning a folder directly with Finder. After some googling i found a very easy, yet very successful fix:
clean your DVD drives lens
Yes, it’s really that simple! I put an old and very cheap DVD lens cleaning DVD in my builtin slotloading DVD drive, let it spin for some seconds and then hit the eject button. After this cleaning Toast started burned my DVD+R DL disk without trouble. I will try it with DVD-R DL next.
Update: even DVD-R DL are working without a problem now!
After playing around with my LaFonera and ddWRT i decided to go back to the original LaFonera firmware. I liked ddWRT for it’s feature-richness, but as my requirements changed i don’t need the router to sit inside the LaFonera and thought it would be good to re-join the fon community
I found most of the commands to achieve this on Stefano Testi’s Blog in this article. I ran into some problems because i tried this on Mac OS X, so i added some steps to this procedure to succeed.

I’ve set my sleepmode of my macbook pro to use the “old” style of sleeping and my mac was very stable and had nearly no problems with waking from sleep.
But as my battery seems to loose capacity i had the problem that if your battery empties very fast in sleep mode 0 (old style), you will loose all data and your mac will shutdown!
Therefore i will switch back to the original setting and as i had to google for how to do it, i take a note in my blog
Old style:
1
| sudo pmset -a hibernatemode 0 |
Standard on new macbooks:
1
| sudo pmset -a hibernatemode 3 |
To check the status:
1
| pmset -g | grep hibernatemode |

i also had some problems with my Mighty Mouse where the scroll ball stopped scrolling down 
i did a quick research and found this link from apple where you’re told how to feedclean your mouse.
and yes, it really worked, i took a wet cloth rubbed the nipple of the mouse in all directions while holding the mouse upside down and voil? – it works again.
if i get problems again in the future or if this doesn’t work, you can try to repair the mouse by dissasembling the enclosure. How this is done without breaking the mouse can be found here
