Click on one point on a widget and drag it to another point on another widget, and a connection (wire, cable, line) is made between the two.
I'm looking for a (open source) web toolkit that has this type of widget, but I don't even know what it is called. So it's a bit difficult to find. Examples would be nice.
Check out this project: https://github.com/sporritt/jsPlumb.
Here's the demo in action: http://jsplumb.org/jquery/demo.html
we have done something like this in Flash ActionScript with getting the initial co-ordinates of the items and the co-ordinates of of the destination position.
Further we called DrawLine function using these for points and it was very eay task.
For opensource i am not sure but it should be very easy in my opinion.

I am in need to draw some diagrams for documentation. Thinks like tables, flow charts, tree, etc.
I usually work in Linux environments and use Latex to write text and write mathematical formulas and equations. What else do you use to draw the things above?
Thanks in advance.
A unsorted list of tools that I generally like:
PGF: A really useful LaTeX macro package for drawing all kind of professional graphics.
Graphviz: A tool to "program" directed graphs and other things with automatical layout.
Balsamique: Web-tool for prototyping GUIs with PDF-export.
Ascii-Art-Tools like Ditaa or aafigure
Dia Diagram Editor: old but usefull GUI for drawing diagrams

This question was asked in an interview. First, I came up with B-tree. He asked me to be more specific and asked me to describe how I would store the data so that it would be easier to retrieve.
Can you please throw some light on this. Thanks in advance
You question isn't really clear.
"Good" ways to store the data depend on what you want to do with it.
If you want access parts of your data, a list of offsets suffices. If you want to search in text, using an additional inverted index in combonation with docIds->offsets is great. If you have frequent updates to your data and reading is rare, none of those make sense. So it really depends
Sounds like an open question, so you can demonstrate your vast experience of ... well, http://en.wikipedia.org/wiki/NoSQL would be my guess, but you could argue that http://en.wikipedia.org/wiki/Dbm answers the question.

There are many applications to recognize similar faces. The most popular is Picasa. How do these applications do the following?
1) Detect face
2) Check for similar in database.
I would read this paper "Robust Real-Time Face Detection" to get started
also this one is interesting

Is there any robust image hashing implementation in any programming language that I can use? This image hashing at minimum be able to generate the same hash for images that are altered in minor form (resized, rotated, minor touch, cropped etc ) .
The best example will be Tineye.com. They somehow hash each image and they are able to detect other duplicate images with minor modification.
I found some research but not implementation.

By this I mean, whats the best way show the uptime of systems? Idealy id like to show some sort of percentage figure, like what the webhosts do. ie 99.5% uptime.
Is there a standard way to determine this?
We use Pingdom to monitor our servers, and they generate the sort of numbers you're looking for (we just use the free account). They also seem to have an API which will let you get your info programatically - no guarantees that'll work with a free account, though.
Hope this helps!
