I have a project that is using a 125Khz RFID cards,dots, stickers.
I need a card reader that has a read length of AT LEAST 4-7 metres.
The reader will collect all tags within that range and check them against an inventory.
I have not been able to find any RFID readers that have this range, and I am not sure if it is at all technically possible.
Does anyone know if this is technically possible with a 125khz RFID?
According to wikipedia http://en.wikipedia.org/wiki/Radio-frequency_identification the maximum range for 120–150 kHz (LF) is 10cm.

I have started some work on SVG graphics and i constantly come across the word ''arbitrary shapes''.
What exactly is an arbitrary shape?
An arbitrary shape is just that.. An arbitrary shape.
The word arbitrary in this context means any as in: not a specified, or specific, kind of shape.
This is not really a programming question though.. But rather an English language question.

One of the key features of Boyer-Moore's algorithm is searching for good suffix. It requires to build a table of shifts on each possible suffix? But how to build this shift table? I don't understand it. Thank you!
There is an excellent explanation in the german wikipedia. I know this might not help, but with a bit of luck you can try to understand the example which is very clear.

I want to do mindmaps which are of the quality of mindmeister that you could include picture and links etc and would be able to export it reasonably well and print it.
I love X-Mind. I don't know if it does what you need, but I only use a small subset of it and still it rocks!
It has a very complete free version that never expires and doesn't contain crapware.

I prefer Freeplane but FreeMind can do the same things:

I am looking for tools which would help me create & analyse surveys. I have a list of about 8000 questions and the answers expected are a fixed set {Yes, No, Can't Say}. Does Excel/Google Docs allow me the liberty to implement such a requirement in short time?
I got my work done via Excel.
