- Forms of URL:
- Menu of all copies of the page:
https://archive.org/*/URL
Harder for user. Have to click to get into one copy.
- Link to a specific copy of the page. Something like:
https://archive.org/20150905220008/URL
Hard-coded for each URL.
- Link to whatever you have for that year/date:
https://archive.org/2015/URL
Server-side logic will find the best match it has for that date.

- finger protocol
-
"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.
- 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.
- Virtual reality
- Virtual reality communities
- 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.

Beautiful. I dreamed of something like this for years
before 2007.
- 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.
Miscellaneous
- Network files with macros:
- Trying to edit a file on network (with sftp) that contains macros.
- Security settings block this.
- Lot of issues setting a network location (with sftp) as a "Trusted location".
- Quick solution:
Copy to C: drive for editing. Copy back to network when done.
- To change to UK English proofing:
Review - Language - change proofing language
- To get high quality images (essential!)
- File - Options (at bottom) - Advanced - Image Size and Quality
- Set for "All new documents"
- Do not compress images in file

How to split a PDF
- online image processing
- online image background remover
(e.g. remove a busy background from a photo)
- online video converters
- Microsoft Paint "Save As" directory:
- If open application for first time, "Save As" leads to some place random like "This PC".
- If right-click on image and open, "Save As" leads to some place random like "Pictures".
- If go into Paint, select dir, select file, make changes, "Save As" keeps current dir.
- If hit "new image" in the previous though, directory is lost.
- So the trick is to start by selecting a file, and always edit existing file and "Save As" rather than starting a new file.
