What is the hipe around 'dependency injection' adapted from Java and introduced in Symfony 2? Could someone give an example of a problem and a solution with and without a dependency injection?

BTW: It's not from Java world only. DI and variations of DIC are used in most of high level programming languages. It's an universal practice helping you to write more maintanable code.

I tired find answer in here, but I couldn't find it.
Thanks in advance.

The problem is that my dll deals with encryption and the key is stored in constant variable. I want the key to be difficult to get. I understand that there's no way to hide it completely, but I hope there's a way to make it difficult to get the key. What could you suggest?
Thank you for your help!
What you are after is specifically tool that is capable of doing "String Obfuscation"
This free tool does it well

You could apply the security update which is going to be released today.
Alternatively, read scottgu's FAQ about it, including interim measures.

This is more of an open question rather than looking for one specific answer.
As we all know there is no one answer that fits all solutions but I am curious to find out how you structure you asp.net MVC solutions and any pitfalls you may have come across in your design or things that you would do differently if you could start again.
The standard asp.net MVC template is just a basic template and I'm sure I've read/heard in a podcast that Scott Hanselman stated the only reason the Model folder is there is so people didn't ask where's the model. This already implies that maybe it should be moved to its own separate class.
Personally in the small MVC apps I've done I've separated out the model into its only class that holds the model and the repository while the 'MVC' project has the controller and the views. This has generally workout without any issues but as I said these have only been small apps.
So what are most people doing?
- Just using the standard template?
- Separating out just the model?
- Separating out the model and the controller?
- Separating out even move so all the data access is done through web services or some sort of data portal?
- Or something totally different?
Finally how are people creating unit tests? Just one unit test class that test each of the projects or a unit test class for each project?
Personally I use Jimmy Bogard's approach: Organizing ASP.NET MVC solutions.
To be honest, most of the time I have found the standard template tidy enough for me to simply re-use it. I would say its really just down to your own particular organizing preferences.
If my model got really large I would definitely consider creating a separate class library project for it.

I'm working with a small team of analysts and statisticians on what will be a medium-sized body of R code. They're smart people, but they're not trained or experienced as programmers, per se. (I am.) They've written some R code, but for our project to be expandable, efficient, and maintainable, it needs to become well-structured, and rather more piratical. One of the better way to learn to be a better programmer is to study elegant existing code. Can anyone suggest some open source examples of R code (on CRAN or wherever) that you think are particularly clear, literate, and good examples? Functional is good, S3 objects are OK, deep magic is bad.
My two favorite packages can both be browsed on R-Forge and are very well documented (although they may be too big for an introduction):
The caret homepage and source code.
The zelig homepage and and source code.
I think that the Google style guide does a great job of capturing the style of the Core team, although Hadley has his own style guide which can be read if you're looking at his packages. You can browse Hadley's packages on Github (and his homepage is full of useful content), in particular:
plyr
ggplot2
reshape
This article on the R-Wiki is also a good read for seeing ways to optimize code.
Not strictly related, but make sure you get them used to using Source Control (perforce, subversion, git, rcs, etc) as quickly as possible. That reduces the learning pains.
