I've been told about car's plate image database that are avaliable on the web for free download to develop image processing and automatic number plate recognition algorithms, does anyone have a link to download or at least some keywords to search on the web?
If it's not legal or is there any ethic issues i would thank if you notice me.
It's perfectly legal to do so, as long as the images are CC (Creative Commons) licensed, or you have permission of the website owner to do.
A quick search for number plate image database yields some results:
Examples of test images
Academic Document (More examples of number plates)
Good small library of number plates.

On eulerproject.net the context is mainly related to mathematics.
Is there a website for practising (and solving) common issues of algorithms, which are non-mathematical?
I am talking about issues e.g. NP-hard problems or good strategies for efficient data handling (divide+conquer, dictionaries..).
Thanks for every helpful answer in advance.
Kind regards
Project Rosalind has a good selection of problems relating to bioinformatics algorithms.
Hackerrank has a choice of problems in categories including NP-complete, Dynamic programming, Graph theory.
you can find problems on topcoder
and there

I was wondering if anyone had knew of a website that provides a great review of data structures and algorithms. I would like it to specifically geared towards interview questions with regards to data structures and algorithms. Would implementation of all of these data structures be something good to review?
Thanks!
This page is a good starting point:
This webpage covers the space and time Big-O complexities of common algorithms used in Computer Science. When preparing for technical interviews in the past, I found myself spending hours crawling the internet putting together the best, average, and worst case complexities for search and sorting algorithms so that I wouldn't be stumped when asked about them. Over the last few years, I've interviewed at several Silicon Valley startups, and also some bigger companies, like Yahoo, eBay, LinkedIn, and Google, and each time that I prepared for an interview, I thought to msyelf "Why oh why hasn't someone created a nice Big-O cheat sheet?". So, to save all of you fine folks a ton of time, I went ahead and created one.

I am a newbie in Matlab field. And i want to learn more about methodology to comparing 2 images to know the similarity between them.
I need more information in international journal / international proceeding, book or another reprort that describe about it.
I Will use it as my literature study.
Is there any suggestion what is the similar journal,book or proceeding that has discussed about it? If has, please include the title and link of them..
Thank You for the attention.
For journals I would recommend the IEEE Transactions on Image Processing:
http://ieeexplore.ieee.org/xpl/RecentIssue.jsp?punumber=83
This is a good general intro from MIT:
http://www.mit.edu/~ka21369/Imaging2012/tannenbaum.pdf
You need to define "similarity" better.
In the image compression sense, similarity is a function of the pixel-wise difference between the images (PSNR, and other metrics).
In a computer vision sense, you would want to see if the two images contain similar content such as objects or scenes. I would recommend using Google Scholar for that.

I'm looking for research papers or studies made on Unit Testing and TDD effectiveness.
Points of interest:
Does TDD reduce Development time?
Does overall development cost reduced as well?
Is the result product more stable?
StudiesOfTestDrivenDevelopment has a summary and more links.
Microsoft Research: Realizing quality improvement through test driven
development: results and experiences of four industrial
teams
An article on infoQ: Empirical Studies Show Test Driven Development Improves Quality.
And a link to the Realizing quality improvement through TDD study.
"TDD seems to be applicable in various domains and can significantly reduce the defect density of developed software without significant productivity reduction of the development team." The study compared 4 projects, at Microsoft and IBM that used TDD with similar projects that did not use TDD.

http://www.thycotic.com/casestudy4.html
Take a look at papers by Nancy Van Schooenderwoert (et al) at www.agilerules.com. In particular "Embedded Agile Project by the Numbers With Newbies"
http://www.slideshare.net/ZendCon/test-driven-development-presentation has a nice presentation explaining TDD though it is geared to Zend and PHP.
http://biblio.gdinwiddie.com/biblio/StudiesOfTestDrivenDevelopment has a number of relevant links
