Computers and Internet Links
- Web directories are for stable, permanent starting points that one can confidently link to.
- Google directory
- This is based on Open Directory (dmoz.org)
- What I used to use:
- Other directory structures:
- Web search engines
are for heavy-duty, once-off user-driven searches.
- Google
- What I used to use:
Books (Search inside books)
Image search engines
Music search
OCR
finger was what people used for self-expression
before the Web and personal home pages.
You would put your "home page" in your ".plan" file,
which finger would display when called.
- finger gateways
- There used to be servers
that could interpret your .plan file
as HTML.

- I'm not into
real-time chatting
any more
(I used to be when I was first on the Internet),
but the idea of
3-D visual worlds
that you can wander round is interesting.
As long as I don't have to talk to anyone.
- Google
- Wikipedia
- Second Life
has a 3-D Dublin.
- TCD researchers
(and here)
have built a 3-D Dublin.
- Most artificial worlds are uninteresting compared to for example
real historic worlds
as they used to be.
I would love to see inside actual historic buildings,
populated by the correct historical characters and their property
instead of by parties of tourists and artificial guides and notices.
I would love to see the following for example:
- Wilton
populated by the family of the 10th Earl.
- Eighteenth century Dublin, where you can wander and turn corners at will.
- Medieval Dublin.
- Medieval Cambridge.
- Over the next century, more and more 3-D models of real worlds, present and historic,
will come onto the Web,
and the whitespace between them will diminish,
so that eventually you can place yourself in College Green, Dublin, in 1790,
and just start walking.
Head out of town, into the countryside, which will all exist in simulation,
and just keep on going.
This international, decentralised, 3-D world, something that could never have existed
before the Web, could eventually become the unifying interface to the world's
historical and geographical information.
-
Google Earth
is now allowing people design their own 3-D versions of real buildings,
and Google will embed accurate designs in their 3-D map.
So the 3-D world can be built in a distributed fashion by thousands of people.
Next step - allow different time periods.

- Google Street View
- IE bug
- If you embed a Google Street View
on a page (with iframe), there is a
bug on IE which will jump to this location
on the page (rather than top of page) on page load.
-
search for discussion of bug
- See the bug
- See fix for the bug
using iframe onload calling a delayed scrollTo
(delay is crucial)
- The above fix may need modifications in these cases:
- If there is a label on the page:
It will always go to the top,
even if the link is to:
file.html#label
- If there is an overloaded page:
If there is a lot to load on the page
(e.g. two Street Views on the page,
or one Street View plus one Google Maps)
then
it needs more of a delay before jumping.
This is an image, not an embedded control:
Click to enter
Google Street View
of Cambridge.
Click to rotate and move about.
Beautiful. I have dreamed of this for years.
- I can write a
6 line program in Shell
to turn my desktop background into a dynamically-updating live view of Dublin.
Ultimately one could imagine a continuous live video background, coming from
anywhere in the world.
Live video cameras could be put in completely inhospitable spots,
like on the outside of trains or aeroplanes, underwater, or on the surface of Mars.
- You can use a layered jpg
to implement inline live video.
e.g. Dublin.
