Web 2.1 ??

Watched some good videos about google wave (from google io 2009), and also a video about the history of how the web evolved until now..
Just been thinking if it is possible to create a distributed version control over all the contents (at least the public ones) of the internet?
If the companies out there just somehow stores every version of their websites, so we (as internet users) do not need to worry about stale links anymore as the company stores it along with the new pages..

if the company goes down, then maybe it can submit the contents (public ones) to a public server maybe ??

problems: copyright..

Some improvements of web2.0?

It would be nice if we can somehow add sticky notes to video??And also if there is a website that can process other websites, simplify their layouts so the end users are not trapped within a complex UI...i.e. www.curtin.edu.au I am at lost when navigating the website..a quick look of it will scare me of not finding what i want.

Tips and Tricks for working with Mobile Terminal.
Introduction

This page is a collection of tips and tricks that people have found useful. Please feel free to leave your own in the comments, but put feature requests in the Issues section.
Tips
Hide the Keyboard

Tap twice quickly on the screen to hide the keyboard. Repeat to bring it back.
Control Characters

You can send a control-C by pressing the "bullet" key (First press ".?123", then "#+=", then the circle on the middle right), then press the C key. This can be useful when you want to escape out of a long running program such as ping. Control-C can also be accessed with a short Up-Right and Control is a short Down-Right swipe, after which the cursor will turn highlight red, from here press any character q, x, c, A to complete or the delete button to exit Control mode.

Escape is control-[ or a short Up-Left swip, which may come in handy with vi. Tab is control-I or a short Down-Left swip (yay tab completion).
Swipe Controls

Swipe Type Direction Action
Short Up-Right Control-C
Short Down-Right Control-
Short Up-Left Esc
Short Down-Left Tab
Short up/down/left/right arrow keys (respectively)
Long Up None (functions as up-arrow)
Long Down Enter
Long Left None
Long Right None
Two Finger Up Config
Two Finger Down Hide Keyboard
Two Finger Left Page-Up/Next
Two Finger Right Page-Down/PREV

None of the Two Finger Swipes seem to work right in 2.0 firmware
Multiple Terminals

Terminal comes with four terminal windows. Tap on the battery icon to go right, tap directally on the time to go left, and tap on the carrier name (AT&T or iPod) to crash Terminal (or do a really quick killall Terminal depending on how you look at it).
Things to do with your terminal

While this is in no way a full how-to for UNIX systems, these are some of the commands that you may find useful for your Terminal.

Mobile Browser + Access Keys

Access Keys is just a shortcut for some commands that you can execute by pressing a combination of keys on the keyboard.

Depending on your browser, you should

* Mozilla Firefox 1.5: hold Alt, press access key
* Mozilla Firefox 2, 3 on Windows and Linux: hold Alt-Shift, press access key
o Mozilla Firefox on Mac OS X: hold Ctrl, press access key
* Internet Explorer 6: hold Alt, press access key
* Internet Explorer 7: hold Alt-Shift, press access key
* Opera (all platforms): press Shift-Esc, then press access key (Shift-Esc will display the list of choices)
* Google Chrome: hold Alt, press access key
* Safari: hold Ctrl-Alt, press access key

See access keys for more information on this concept.

1. Have a look at .hg\requires file and maybe delete the line that has fncache
2. Try cloning it again hg clone ssh://user@host//path
