The problem is with the ath9k driver.

The fix is in a more recent version of the ath9k driver. To install it, simply install the linux-backports-modules-karmic and linux-backports-modules-wireless-karmic-generic packages:

david@continuity:~$ sudo apt-get install linux-backports-modules-karmic linux-backports-modules-wireless-karmic-generic

Next: reboot.

Simple as that.

ps. Technically, you should be able to unload the old module and load the new module, but my laptop didn’t seem to play well with that… or, at least, the Network Manager in Ubuntu didn’t like it. When in doubt, take the Windows approach: reboot.

To install Eclipse 3.4, grab the appropriate download from http://www.eclipse.org/downloads/packages/eclipse-classic-34/ganymeder. Keep in mind, it’s big, approximately 150MB.

Once downloaded, extract it. In my case, I unzipped it to my own $HOME/bin directory, as I didn’t want to mess with the system installation of Eclipse 3.5. This will create an eclipse subdirectory containing an eclipse binary.

As I’m only going to be using this version of Eclipse for working with Force.com, I renamed the unzipped directory and created an alias for convenience.

david@continuity:~/bin$ ls
eclipse
david@continuity:~/bin$ mv eclipse eclipse-3.4

I added my alias to $HOME/.bashrc:

alias force.com=$HOME/bin/eclipse-3.4/eclipse

If you wanted to go even further, you could create a launcher in your applications menu or on your toolbar or desktop. However, I’m not that in love with Force.com (or even Eclipse)…

Next, launch Eclipse and follow the installation instructions for the Force.com IDE at http://wiki.developerforce.com/index.php/Force.com_IDE_Installation_for_Eclipse_3.4.x. There’s no point in me repeating those instructions – they’re comprehensive and easy to follow.

Enjoy.

So, to get testing done in a more timely manner, I’ve had to resort to quick hacks at the command line to test the Cubetree API, verify their message format, etc:

david@continuity:~$ curl -d "login=MyUsername&password=MyPassword" -D headers https://www.cubetree.com/api/v1/login && curl -s -b headers https://www.cubetree.com/api/v1/feed | python -c "
import sys
for item in eval(sys.stdin.read()): print 'Creator: %s\nAction: %s\n' % (item['creator-name'], item['action'])
"

. . .

Creator: David Taylor
Action: has to keep reminding himself: Although a Cubetree integration would be much easier with Ruby/Python/C#/etc (any common language, really), Force.com can make other tasks much easier 

Creator: David Taylor
Action: got the custom setting code to work in Force.com ... it required knowing about an undocumented variable, SetupOwnerId ... go on, try Googling it and see for yourself  :-) 

. . .

All in the name of good, clean fun.

dovecot: IMAP(nerida [AT] mygreenme.com.au): Ambiguous mail location setting, don't know what to do with it: /var/spool/vmail/mygreenme.com.au/nerida/ (try prefixing it with mbox: or maildir:)
dovecot: IMAP(nerida [AT] mygreenme.com.au): Mail storage creation failed with mail_location: /var/spool/vmail/mygreenme.com.au/nerida/

Curiously, this has never occurred before, even though I provide virtual hosting services for other domains in the same manner.

Not to worry…

The fix requires finding the dovecot query that produces the mail= value and prefixing it with the desired mail format. I prefer maildir:. So, in my case, that involved editing /etc/dovecot/dovecot.conf and changing from:

  userdb static {
    args = uid=vmail gid=vmail home=/var/spool/vmail/%d/%n/ mail=/var/spool/vmail/%d/%n/
  }

to:

  userdb static {
    args = uid=vmail gid=vmail home=/var/spool/vmail/%d/%n/ mail=maildir:/var/spool/vmail/%d/%n/
  }

Simple.

Oh, also, in the logs above I changed the “@” symbols to ” [AT] ” … my wife would never let me live it down if I primed her new mail account with spam.

The Blueman Project

To get started, you will need to add the repository for the blueman project. As root:

root@continuity:~# add-apt-repository ppa:blueman/ppa
root@continuity:~# apt-get update
. . .
root@continuity:~# apt-get install blueman
. . .

After it is installed, you may need to start/restart the bluetooth service.

root@continuity:~# restart bluetooth

Enable Bluetooth

If, like me, you’re using GNOME, you can find the new Bluetooth Manager in your menu under System -> Preferences. Start the Bluetooth Manager. Its icon should appear in your task bar. Left-click on the icon to open the Bluetooth Manager interface. At this point, make sure you have enabled bluetooth on your computer (typically a switch or button on your laptop… or even a USB dongle for your desktop).

Enable bluetooth on your iPhone. Go into the Settings application, press the General button, then press the Bluetooth button. Press the Bluetooth switch to turn it on. The interface should now say Now Discoverable.

While you are searching for your iPhone and pairing with your iPhone, you need to make sure your iPhone remains on and unlocked and in the Bluetooth screen. Your iPhone is only discoverable while in this screen.

Pairing

Back to the Bluetooth Manager interface on your computer. Press the Search button. A list of visible bluetooth devices should appear (if there is more than one visible bluetooth device in the vicinity) and one of them should be your iPhone. Your iPhone will be identified by the name you have given it using iTunes (in my case David’s iPhone) or by the default name, iPhone.

If you see multiple iPhones you will need to select the one that has a matching bluetooth MAC address for your iPhone. To determine your iPhone’s bluetooth MAC address, go into the Settings application on your iPhone, press the General button, press the About button, then scroll down to the Bluetooth value. Your iPhone will be listed in the Bluetooth Manager interface with this address as a sub-heading. Take a note of this and make sure you go back to the Bluetooth screen so that your iPhone is discoverable again.

Back to the Bluetooth Manager. Select your iPhone. Click on the plus icon to register it.

For the next step, you will need to select a 4 digit passcode to use to authenticate your computer to your iPhone. Click on the keys icon. A dialog box will appear. Type in your chosen 4 digit passcode and click on OK. Your iPhone should now prompt you for a passcode. Enter the same 4 digit passcode. Your computer and iPhone are now paired.

Enable Tethering

Enable internet tethering on your iPhone. In the Settings application, back in the General settings, press the Network button. Press the Internet Tethering switch to turn it on.

Back to the Bluetooth Manager on your computer. Right-click on your iPhone and click on Connect To: Network Access Point. After a short while, a new network connection should be announced in your task bar. In the Bluetooth Manager, select your iPhone and click on the star icon to indicate that you trust this device.

Finished

From now on, as long as bluetooth is enabled on both your computer and iPhone and internet tethering is also enabled, you will be able to right-click on the bluetooth icon in your task bar and connect to the internet via your iPhone.

While you’re not using Bluetooth and Internet tethering, I highly recommend you disable them on your iPhone and laptop to conserve battery power.
