ubunut 10.04 Lucid Lynx "panel not responding"

I upgraded from 9.10 to 10.04 and started facing a weird issue - sometimes the gnome panel doesnt load.
I used to do a reboot until the panel loads properly.
Today even after the second reboot it didnt load properly.
I did search and found that gnome-weather-applet is the culprit ( thats one of my fav apps :( )
I want to kill the gnome-panel and start it again. ALT+F2 didnt work for me

This is what helped me :

Right click the desktop and choose 'Create Launcher'.
Give it a name like Terminal the command is 'gnome-terminal'
Click OK

Now, run the terminal and kill the gnome-panel
$ killall gnome-panel
and start it
$ gnome-panel --replace
Your panel and system should be completely functional now minus the weather applet.

(You can disable the weather applet next time the panel loads fine or boot with live cd and disable it)
This is the bug https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/482690

django makemessages - invalid multibyte sequence error

Today I was trying to run $ django-admin.py makemessages -a to pull the strings marked for translation from a django app.

I was getting the error invalid multibyte sequence

The problem was that the .po wasn't encoded properly.

This is what helped me.

(on ubuntu 10.04 Lucid Lynx)

1. $ file -i filename

This would give you the MIME type of the file

2. $ iconv --from-code=ISO-8859-1 --to-code=UTF-8 iso.txt > utf.txt

--from-code is what is returned from step 1

3. $ django-admin.py makemessages -a

Hurray no errorr now.

RT Installing Flash player from repository on Ubuntu 10.04 64-bit «

My previous post on this subject provided a quick way of getting Adobe Flash player working under Ubuntu 10.04. It used a rather nice shell script, which got Flash player working, but obviously at the expense of updates via the Ubuntu repositories. I’m now happy to report that I have Flash player working from the repositories. Here’s how to do it:

Go to System -> Administration -> Software Sources and check the “Software restricted by copyright or legal issues (multiverse)” box.

Click on the Other Software tab and ensure that http://archive.canonical.com/ubuntu lucid partner entry exists. Your settings should look like the following images:

Software Sources Software Sources
Click Close and allow the repositories to update.
Now download and run this shell script, which will purge any changes made by the previous previous shell script or attempted installations. It will then install Flash from the correct repository. To do this:

Extract the file to your home directory.

Open a Terminal window and type:
chmod +x ~/new-64bit-flash-installer.sh
~/new-64bit-flash-installer.sh
Allow this to complete, and you should have a fully working 64-bit Flash player, which will be updated by the repositories.
