Download the android source as a zip

Hmmm, the repo script doesn't appear to be working thanks to conflicting variables on the work set up. So to get a zip of the android source I went to http://rgruet.free.fr/public/ and downloaded the latest.

All the other google results were severely outdated.

compile kernel module from c file

make -C M=`pwd`
That is all. .ko sitting there:

Installing libkeyutils-dev solved the problem.

How to grep for tab

Enable the location bar in nautilus ubuntu's file browser.

The more and more I sit with Ubuntu I find myself in gconf-editor doing things, whether it's adding the week to the time (handy in European workplaces), making the minimize maximize and close buttons sit in the correct corner with the correct order, or in this case get that location bar back.

So the steps:

$ gconf-editor

apps->nautilus->preferences->always_use_location_entry

You could do this in one line, but I'm sure there's a few other things in gconf-editor that will keep you busy.

BankID Ubuntu 10.04 64-bit

Ahhh the woes of a 64 bit machine bite again. I'm still Using Ubuntu 10.04 (I haven't seen anything worth upgrading for) so installing BankID isn't a problem as Swedbank's sucurity program has a Ubuntu distribution. But getting it to show up in Firefox is the step that they leave out of the instructions.

The missing line is:

$ nspluginwrapper -i /usr/local/lib/personal/libplugins.so

ns plugin wrapper wraps your 32 bit plugin so that your 64 bit machine can use it. After restarting your browser, in your Tools -> Addons -> Plugins you should see a Nexus entry which is your bank ID.

Now I don't need to switch back to windows for anything.
