I am looking to buy a good book on data visualisation and would love to here your recommendations. My background is mathematical and I am currently working on a data analysis tool for my employer. The two books that have intrigued me so far are
The Visual Display of Quantitative Information by Tufte
Interactive Data Visualization: Foundations, Techniques, and Applications by Ward
I'm more interested in algorithms and efficient ways to analyse the data. I'd like a book that could explain how to make graphs similar to the ones on this website.

The list post suggested by #gary comtois is great, but if you are looking for algorithms I would suggest looking at:
http://oreilly.com/catalog/9780596514556
It assumes programming knowledge but isn't the most challenging of books. However it covers plotting graphs, treemaps and other things.
The bibliography is also quite good.
Hope it helps.

I've been programming with OOP for a year. But I think sometimes, my solutions to the problem, code quality and so on, is not the best as it could be. Are there any good books on writing good and quality OOP code (programming language doesn't matter) for advanced programmers? What would you recommend?
I'm reluctant to suggest a "patterns" book, but Design Patterns is pretty good. It's much more descriptive than proscriptive -- and some of the patterns won't make any sense at all, until you've fought the underlying problem that leads to the patterns -- but if you read the book with the mindset that they are trying to provide a grammar that programmers can use to talk about problems rather than tools that are the Best Possible Solutions, then it is an excellent book.

I'm looking for some callable way to get information about famous people and celebrities. Given a string, I'd like to determine if it's the name of a famous person, and if so, if they're alive and perhaps what category they fall into (e.g. Actor, Musician, Athlete).
Does anyone know of any publicly available APIs to do such a thing? The best I can come up with is Wikipedia, but it's pretty problematic because much of the info must be parsed, and isn't in a reliable and predictable format.
I'd also like to be able to offer suggestions for possible names when the initial search turns up nothing (since the strings will be from people and may contain misspellings).
Try DBpedia, the "preparsed" (RDF) version of Wikipedia. It can be queried using SPARQL. It includes much of the info in the English-language Wikipedia.
Try the Wikipedia API:

It appears there's also an API for IMDB:

I have done some research and found test plan over 40 pages. It includes so many elements that it is difficult to keep track. Additionally, it is not provided any examples, just a description of the different tests such as acceptance test, system test, etc. If anyone have made some good and simple test plan for the development of a product and could share, so that I can gain inspiration with example would be very helpful.
yeah, i find that a pain to when i just want to do the thing, and people explain around it - im like "just bloody show me an example template i can rip off!"
this is why i write my articles with a pragmatic approach (e.g. Writing a System Test Plan)
its short, has an explanation of the reasoning behind the test structure, and gives the actual template

I'm new to the VxWorks Environment are there any good sources of information out there?
2 Books helped me:
Real-Time Concepts for Embedded Systems ISBN-10: 1578201241 ISBN-13: 978-1578201242
(Basic RT concepts, Common Patterns)
Tornado and VxWorks: What's not in the Manual ISBN-10: 3833410698 ISBN-13: 978-3833410697
If your budget allows it, I would recommend taking one of the courses offered by WindRiver. My company brought in one of their trainers to teach a class on-site and it was excellent. They provided hands-on programming activities and a lot of information. If you are new to the concepts of real-time or embedded programming, they provided the necessary background information, and even if you were already familiar with these (as I was), there was plenty of useful training specific to VxWorks and Workbench. I believe they also organize their own courses, in addition to coming to companies. Course Schedule

I need to implement a Diff algorithm in VB.NET to find the changes between two different versions of a piece of text. I've had a scout around the web and have found a couple of different algorithms.
Does anybody here know of a 'best' algorithm that I could implement?
Well I've used the c# version on codeproject and its really good for what I wanted...
http://www.codeproject.com/KB/recipes/diffengine.aspx
You can probably get this translated into VB.net via an online converter if you can't do it yourself...
I like An O(ND) Difference Algorithm and Its Variations by Eugene Myers. I believe it's the algorithm that was used in GNU diff. For a good background see Wikipedia.
This is quite theoretical and you might wish to find source code, but I'm not aware of any in VB.
I don't know for sure if it's the best diff algorithms but you might want to check out those links that talks about SOCT4 and SOCT6
