Touchpad Mod Upgrades – Bump to Cyanogenmod Alpha 2 and WebOS 3.0.4 while maintaining dual boot heaven (easy)

Note: I performed the below from Ubuntu 11.04 x64

After this process, you will be on CM7 a2 (newest Cyanogenmod – steps 1-2) and WebOS 3.0.4 (newest – steps 3).  Once you pull the WebOs update, moboot (what let you pick which OS to boot to) will no longer be the active bootloader.  But we have you covered (steps 4 – 7) – you will be booting via moboot in no time flat!  WOOT!

 

1) Download CM7 a2 update from here (http://rootzwiki.com/showthread.php?4011)
2) Upgrade to CM7 alpha 2 via clockworkmod Clockworkmod using the file obtained from step 1
3) After CM7 upgrade, reboot into web os and pull 3.0.4 OTA WebOs update
4) Connect Touchpad to PC and put in USB mode.
5) Create ‘cminstall’ folder on touchpad and then copy ‘update-moboot_0.3.3.zip’ to the folder (should have this file from when you installed CM7 a1).
6) Eject Touchpad and restart into USB Mode (Large White USB Icon) by  holding “Power + Volume Up”
7) Locate the ACMEInstaller that you originally loaded CM7a1 on your touchpad with and execute “novacom boot mem:// < ACMEInstaller” from terminal and let it do its magic…

You are up to date to date and dual booting again with the latest and greatest.

Critical error on Couchapp push with Ubuntu

I am hoping that in posting this, someone is able to save a little time and frustration.

On my Ubuntu 10.10 machine with CouchDB 1.0.1 installed, I began experiencing the following error every time I attempted to ‘couchapp push’ my couchapp changes:

[CRITICAL] Expecting object: line 2 column 3 (char 4)

After a bit of noggin scratching (and perhaps a little mumbled cussing), I started thinking about the fact I had not upgraded my couchapp install since long before I last upgraded CouchDb.

Running the following cleared up all error and put me back in the happy land of  ‘couchapp push’:

“easy_install -U couchapp”

Yup… Just a version issue…  Hope this saves someone a few gray hairs…

Restarting Vino-Server from CLI

As is often the case, I am posting this here just as much for myself as I am for others Googling this problem…

Sometimes Vino-Server on Ubuntu can be flaky, preventing me from logging in, even though it is showing as running. I recently stumbled onto a helpful thread at UbuntuForums that assisted me…

Using the following, you should be able to get Vino back to behaving…

you@machine-name:~$ export DISPLAY=:0.0
you@machine-name:~$ /usr/lib/vino/vino-server &

I find this particularly useful when I am able to SSH in, but can’t VNC…

Hope this helps someone!
