This is because Google uses geo-targeting to determine what results you may be interested in (assuming your geo-location from your IP address), and because of the Google data centre that you are getting connected to (updates of search results and their ranking is not instantaneous across the globe), and because if you are logged in to Google (mail, et al) your search history will bias the results you may receive, and because recent searches (whether logged in or not) are cached and will affect what you're getting served. People searching for pubs in the UK are bound to get different results to people searching for pubs in Australia. Of course if you want to search for pubs in Australia while you are browsing from the UK things are going to get tricky ... In such cases you want to add: The location in the search results: e.g. pubs + Australia (to filter the UK Google results for Australian pubs), or go to www.google.au and then search from there for pubs (Australian Google results for pubs). There could be other more sophisticated ways but can't recall them off hand. Now, if someone sends you a non-lmgtfy.com link you can look at the Google TLD to determine the country the results are from and search accordingly. > > SCNR :P > > shortcircuit:12@serenity~ > Fri Sep 23 08:44 AM > !501 #1 j0 ?0 $ wtf is scnr > SCNR: sorry, could not resist > > Ah. > > > alternatively you could use catalyst: > > http://www.gentoo.org/proj/en/releng/catalyst/ > > > > or you just mount the iso, modify it, run mkisofs on it and burn it. > > the mkisofs options you are looking for are -b and -c. > > I knew there was going to be something I wasn't going to know, and it > looks like the values passed to -b and -c are it. > > I don't want to build a CD from scratch (and doing so looks like it > would require setting up a fully "generic" box to build).

Mount the ISO with loopback and then navigate into it as a normal fs: # mkdir /mnt/iso # mount -o loop LiveCD.iso /mnt/iso # ls -la /mnt/iso # cp /mnt/iso/some_file -- Regards, Mick
