I'd like to learn a few more languages to "expand my mind" a bit, and I find working through problems the best way to learn. I have been doing most of my programming in C, sometimes C++, and perl. With these tools, I seem to be able to solve the problems I encounter, but you know the expression "when you have a hammer, everything looks like a nail?" I feel like I am stuck in a single paradigm, and I would like to change.
What I'm looking for is a resource similar to Project Euler, but with more generic/real world problems(Project Euler is very mathematical) which highlight the benefits of different languages. The idea would then be to work through the problem set with each language and note the relative difficulty of completing each problem in the given language.
1) Does such a resource exist?
2) What are some problems you would include? Remember: these should show the strengths of each language.
Thanks!
CodeChef (http://www.codechef.com/) and Sphere Online Judge (https://www.spoj.pl/problems/classical/) both look like good options for you. Their problems aren't necessarily practical, but they are less explicitly mathematical than Project Euler, and their judges accepts programs written in plenty of languages. The Python wiki recommends a few others (http://wiki.python.org/moin/ProblemSets), but they aren't quite as flexible.
I haven't used either site, so I can't recommend any specific problems. Just make sure to include some logic problems so you can revel in the awesomeness of prolog :)

as the final project for a programming course I took I've made a small tool which deals with databases issues. It works and I think it could be useful to others, so I'd like to put the code on the net to see if it actually is.
I'm aware of various source code hosts such as GitHub or Google Code, however they seem more oriented towards group development and I'm not sure if they're good for individual complete projects as well. I'm not saying I'm opposed to collaboration, but those platforms just seem a bit too much for something so simple.
Does anyone have any idea on how I should share the code?
Github would be fine - just because git allows multiple developers on a project doesn't mean it is required.
Most of the complexity is there if you need it but you do not have to ever visit those screens. The last time I looked at the network view for my more complex projects was a long time ago!

There is a site that I would like to replicate i would like to know how there database is structured. Is there a tool that can help with this process?
That's not possible because the web pages do not have (direct) information on the underlying data dictionary. They have HTML, JS, CSS. They have no data model not even SQL queries.
You can look at the HTML/JS code which might give you some ideas, that indirectly, lead you to a possible design. This is the work any professional database designer should be able to do.
You would need to ask the web site owners what is the data dictionary or use some form of cracking (illegal in most countries, I guess) to have access to the server/dbms.
But even if you could have access to the data dictionary it is not necessarily obvious how that translates into the web pages you are vieweing. That's because usually there is data transformation (business rules) to arrive to the web pages, usually through some form of templating.
What you need is reverse engineering, and for that the main tool is the brain. You could use some scripting to extract useful data, eg, label elements or table headings.

I'm currently about to begin work on a project and I'm wondering which library is the best to use.
The project is to create a simulation of a particular scenario. It's main requirements are:
Animation on various parts / objects
User input for some variable, including the constructor parameters of some objects.
Collision detection
Flood algorithm.
Images will be required and the 'pattern' aspect of fabric would be perfect for a couple of objects
I'm attempting to model the Macondo well disaster.
I recently discovered Fabric js and was excited, very excited at the prospect of being able to use objects. I then looked a bit harder and found many other libraries that are available.
I'd like to ask what the benefits of using Fabric js are over those of the alternative libraries. From what I've described, would Fabric be able to cater to all the requirements and would an alternative framework be a better solution?
Thanks for any help.

Does anyone know of any good obfuscation tools, plugins and or scripts that will work well with Actionscript? Since AS3 is based on ECMAScript I'm guessing that Javascript obfuscators might work as well.
Ideally I'm looking for something that would allow to set the level of obfuscation, or to only obfuscate parts of code, ie variables or private methods, etc.
If you want to protect your final SWFs, you'll need to obfuscate the SWF rather than obfuscating the source code. While changing variable / function / etc names in the source code before compilation will provide some protection, it makes the process much more complex and misses out on several additional levels of possible obfuscation available by processing the compiled SWF.
There are numerous SWF obfuscators available; here's a topic that covers that (note all of the linked topics on the right-hand side). My personal favorite is secureSWF.
I use Flash Secure Optimizer cheap and secure
There is no need to obfuscate your code since it is compiled and that will take care of it. Now if you are referring to a de-compiler then don't because it will correct all your obfuscation.

I'm just about to rewrite my personal site as a learn-as-you-go project and am thinking of open-sourcing the code (see this question).
Are there any examples of large-ish web sites (not desktop applications) which have made their code open-source? Or is this generally thought of as a bad idea because it would be easier for a malicious hacker to find any security holes in the code?
WordPress is the best example, I can think of in your case.
And, the security implications come from the loopholes, you might leave by mistake or in coding process. But, then when you are open-sourcing the project, a lot of people may contribute and help you resolve those issues, which is how WordPress also works. They have a bug-tracker setup for them for this purpose.
