This is because Google uses geo-targeting to determine what results you may be |
| 21 |
interested in (assuming your geo-location from your IP address), and |
| 22 |
|
| 23 |
because of the Google data centre that you are getting connected to (updates |
| 24 |
of search results and their ranking is not instantaneous across the globe), |
| 25 |
and |
| 26 |
|
| 27 |
because if you are logged in to Google (mail, et al) your search history will |
| 28 |
bias the results you may receive, and |
| 29 |
|
| 30 |
because recent searches (whether logged in or not) are cached and will affect |
| 31 |
what you're getting served. |

People searching for pubs in the UK are bound to get different results to |
| 35 |
people searching for pubs in Australia. |
| 36 |
|
| 37 |
Of course if you want to search for pubs in Australia while you are browsing |
| 38 |
from the UK things are going to get tricky ... |
| 39 |
|
| 40 |
In such cases you want to add: |
| 41 |
|
| 42 |
The location in the search results: e.g. pubs + Australia (to filter the UK |
| 43 |
Google results for Australian pubs), or go to www.google.au and then search |
| 44 |
from there for pubs (Australian Google results for pubs). There could be |
| 45 |
other more sophisticated ways but can't recall them off hand. |
| 46 |
|
| 47 |
Now, if someone sends you a non-lmgtfy.com link you can look at the Google TLD |
| 48 |
to determine the country the results are from and search accordingly. |

Mount the ISO with loopback and then navigate into it as a normal fs: |
| 76 |
|
| 77 |
# mkdir /mnt/iso |
| 78 |
# mount -o loop LiveCD.iso /mnt/iso |
| 79 |
# ls -la /mnt/iso |
| 80 |
# cp /mnt/iso/some_file |
