Upgrading to 10.8.2 will install java7 and disable java6. Java7 is only 64 bit, chrome is 32 bit.
Fix:
1 2 3 4 | sudo mkdir -p /Library/Internet\ Plug-Ins/disabled sudo mv /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin /Library/Internet\ Plug-Ins/disabled sudo ln -sf /System/Library/Java/Support/Deploy.bundle/Contents/Resources/JavaPlugin2_NPAPI.plugin /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin sudo ln -sf /System/Library/Frameworks/JavaVM.framework/Commands/javaws /usr/bin/javaws |
NOTE: Enabling java6 might introduce security holes.

Open /etc/xdg/autostart/update-notifier.desktop, find NoDisplay and edit it to false.
154 155 156 157 158 159 160 161 162 163 | ... Icon=update-notifier Exec=update-notifier Terminal=false Type=Application Categories= NotShowIn=KDE; NoDisplay=false X-GNOME-Autostart-Delay=60 X-Ubuntu-Gettext-Domain=update-notifier |
Update-notifier will then show up in the application gnome-session-properties, where it can be disabled. When disabled, a modified version of update-notifier.desktop is written to ~/.config/autostart/.
Windows 7 system image backup saves the whole windows partition in raw format inside a VHD-file(Virtual Hard Disk). The VHD format is also used in virtual environments, as Hyper-V and Virtualbox. Unfortunately Windows system restore is limited in the capability to restore to another disk layout. But with the use of vdfuse in virtualbox-fuse(universe) it's possible to restore the partitions manually with a Ubuntu Live system. Then you are in complete control yourself, disk layout etc.
This was done to restore a system disk(crashed SSD) to a regular hard drive which was already in use (contained the backups). The partition on the regular hard drive was moved to make room for the system partitions in the beginning, and the backup was mounted through vdfuse and restored with dd.
Walk through
Prepare a Ubuntu Live system(USB, cdrom, etc) and boot it. Partition the new disk with GParted. In my special case, I moved my existing partition to the right/end of disk. Then I noted the new placement:
1 | sudo fdisk -l /dev/sdb |
I'm not sure where Windows system image stores (if it does) the MBR, but you could search through the WindowsImageBackup folder for a file of 512 bytes. Most likely, it manually creates the partitions and writes a fresh boot sector. This can also be done by creating the partitions and using a Windows install disc/USB to repair the startup. There should be a 100MB "System reserved" primary partition with bootflag enabled, and the Windows partition itself. Here I just copy the working MBR from the crashed disk:
1 2 | MAKE SURE YOU KNOW WHICH HARD DRIVE IS WHICH BEFORE USING DD sudo dd if=/dev/sda of=/dev/sdb bs=512 count=1 |
Then I added the already moved partition (the data is still there, we just lost the reference to the partition when moving MBR from sda to sdb).
1 | sudo fdisk /dev/sdb |
If you haven't a moved a partition, skip this step: Reboot computer, use an Windows install disk to check the integrity of the moved partition (chkdsk), when done boot Ubuntu again.
Add universe to apt sources(/etc/apt/sources.list):
1 2 3 4 | ## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu ## team. Also, please note that software in universe WILL NOT receive any ## review or updates from the Ubuntu security team. deb http://archive.ubuntu.com/ubuntu/ precise universe |
archive.ubuntu.com can be replaced with your local mirror. Usually the local mirror is named XX.archive.ubuntu.com, where XX is your country code (no for Norwegian -> no.archive.ubuntu.com).
Update apt and install virtualbox-fuse:
1 2 | sudo apt-get update sudo apt-get install virtualbox-fuse |
Mount the partition which contains the backup (WindowsImageBackup directory). Find the VHD-files. Create two empty directories and mount the VHD-files(read only):
1 2 3 4 | sudo mkdir /media/f1 sudo mkdir /media/f2 vdfuse -r image-file1.vhd /media/f1 vdfuse -r image-file2.vhd /media/f2 |
Inside the VHD-files, there is a Partition1 file. This is the raw image of the partition backed up. In f1/f2 you should find one Partition1 file which is 100MB, and another which is the same size as your Windows partition. You could mount these files to look at the backup:
1 2 3 4 | sudo mkdir /media/temp sudo mount -o loop,ro /media/f1/Partition1 /media/temp ls /media/temp sudo umount /media/temp |
When ready, use dd to copy its contents to you new partition:
1 2 3 | MAKE SURE YOU KNOW WHAT YOU ARE DOING, DD DOES NOT CARE ABOUT YOUR IGNORANCE!! sudo dd if=/media/f1/Partition1 of=/dev/sdXX bs=64M |
if is the input file, of is the output file. XX is the partition, one character and one number. sda1 is sda's first partition, sdc3 is sdc's third partition.
Umount the partition with the backups, reboot and cross your fingers.

This was done with Atheros AR5001 (ath5k, Linux Mint 10, 2.6.35).
Install hostapd and DHCP-server.
1 | apt-get install hostapd dhcp3-server |
/etc/hostapd/hostapd.conf:

Add with to sudoers(with visudo):
1 2 | # Allow admin users to share internet connection %admin ALL=NOPASSWD:/usr/local/bin/ics |
Add shortcut to desktop with command "sudo /usr/local/bin/ics start" and "sudo /usr/local/bin/ics stop".
I have a backintime running every hour. Sometimes, it's running when I suspend/hibernate the machine. The suspend will fail, because backintime refuses to suspend. BIT will fail because network is pulled down. Then we have backintime running forever, and suspend/hibernate failing forever too(until you kill BIT manually).
This script will wait until backintime is done, and then let the computer suspend/hibernate.
/etc/pm/sleep.d/01_backintime:
1 2 3 4 5 6 7 8 9 10 | #!/bin/bash case "${1}" in hibernate|suspend) while pgrep -f "/usr/bin/backintime "; do sleep 5 done ;; esac exit 0 |
Remember to make the file executable.
Run this script at startup of Gnome.

Some file systems hangs on resume from suspend/hibernate, especially network file systems and FUSE-filesystems(encfs by example). I've created a script to unmount file systems when suspending/hibernating:
