As we all know, varScoping your ColdFusion code is an absolute must for any non-trivial project.
CF9 brings many enhancements to CFScript, such as being able to write entire CFC's in script, including component, function and property tags.
However varScoper won't work with cfScript defined functions/components. It just doesn't attempt to check functions declared in script.
The question is, what is everyone using for varscoping their cfScript based CFC's?

VarScope is under an Apache licence, so is "open source". You could always touch base with the bloke in charge of it and see if he'd be interested in third-party updates to it, and perhaps you could make the changes yourself? It would certainly earn you community brownie points!
Not an entirely satisafactory answer, I know.
To answer your actual question: until CF has full CFScript coverage for the functionality we use (or are likely to want to use) in CFCs we won't implement any script-only CFCs. And for our tag-based ones we just use a tight coding standard and have code peer review before committing anything for release. Occasionally we run varscoper, but it does a less good job of finding problems than two sets of eyes do: varscoper does seem to come up with a lot of false positives.
Another consideration is that if you have 100% unit test coverage (yes, I know: who does?) then checking what's in the variables scope of a CFC after you've run your tests will show up any leaks into the variables scope.

I have been research on what is unit testing, integration testing and system testing.
I am writing a thesis on an exam system I am creating using php, jquery, javascript and mysqli programming. It is basically an exam system which connects to the database where the teachers are able to create exams and students take the created exams.
Anyway what my question is that does anyone have an examples or know any useful websites of different techniques to use to be able to fulfil these types of testing methods. If you can name these procedures then I will be more than happy to research those methods and be able to include those in my testing methods in my thesis.
When you provide an example or name the techniques, can you state if they are either unit testing, integration testing and system testing.
Thank you very much :)
Take a look at that, I think it will be helpful for you: http://www.istqb.org/downloads

With respect to this question, is it always necessary to have perfectly concurrent-safe web-application or can a developer afford to let some possible concurrent issues untreated (e.g. when money is not involved) because probability of them happening is very low anyway. What is the best practice?
NOTE: If I say concurrent issues I mean the issues raising from overlapping executions of scripts. I do not mean the multi-user issues like classic lost-update with the timestamp solution cause probability of these things is imho significant and I am pretty sure here that the best practice is to always treat them.
If you're going to run your code on a web server, you should always write your code in such a way that multiple copies of it can run at the same time.
It's really not that difficult. In most cases database transactions around state modifying operations is all that is needed (or using a lock file, or any of the other well-known solutions to this problem).
Note: if all you're doing is reading data then there are no concurrency issues.

This question may seem to be naive.
But I think it'll be much worse if I don't ask it at all.
When a discussion begins about the features of Python that the developers love the most, they usually mention list comprehension, syntax relying on indentation (thus avoiding brackets, etc.) and some other.
At such moments I ask myself a question why there can't be made a language based on C++ but having a syntax like in Python and having all the features like list comprehensions, generators.
I understand that such a language won't have all the features that Python has, e.g. eval or exac statements (because they rely on Python being an interpreting language), may be some others that I don't know of.
But I also know that there is a project called Shedskin which makes a C code of a Python code (with some restrictions on what can be used in Python code).
So, are there some real reasons why it's impossible to create such a language that will combine all the best features of Python and a very fast code that produces C++? Or it's just the turn of events that Python for some reasons became very popular and it turned out to be interpreted, so a lot of people use it for its greatest features still discontent at the speed of the code, and some of them struggle to create something (like Shedskin or Psyco) to speed it up?
Google as created a language called Golang ( or Go). It is a compiled language with python like syntaxe. There are alot of video and documenttation that will answer your question there.

Is there a DI framework comparable to Google Guice? And what does Google use?
There is nothing as mature or standard as Guice in the C++ world. However, some people have put together simplistic implementations on their own. Here's a couple.
http://adam.younglogic.com/2008/07/dependency-injection-in-c/ (source for implementation is at the end of the post)
http://sourceforge.net/projects/qtioccontainer/ (requires Qt)
http://code.google.com/p/autumnframework/ (hasn't been touched since 2007)
http://programmaticallyspeaking.blogspot.com/2010/04/beautiful-dependency-injection-in-c.html (more of a description, really)
http://sourceforge.net/projects/cpp-resolver/ ("Alpha" quality)
You're unlikely to be satisfied by any of these.
If you really wanted to put in the effort to rally the world around a DI framework for C++, probably the way to go about it would be to make a proposal to the Boost guys.
I'm the author of wallaroo. It's actively developed and has the following features:
it's lightweight but powerful
its interface supports both C++11 and C++98 with boost
it's type safe
it doesn't need custom preprocessors / code generators
you can load classes defined in shared libraries
you can use a DSL syntax for object creation and wiring or
you can get object creation and wiring by parsing one or more xml / json file.
Any comment, suggestion or request are welcome.
There is a recent one that looks very interesting called Hypodermic, i haven't tested it but it looks pretty active
I am currently authoring one called sauce, whose design (and name) is directly inspired by guice. I still consider it alpha, but you may find it useful.

I'm trying to set up a really basic e-commerce site with Django, and am trying to figure out the best place to start. I am relatively comfortable with the framework itself, but have never done any sort of e-commerce development in any language, so I want to learn about some best practices so I don't make any huge or obvious mistakes.
I've looked at Satchmo, and even went as far as installing and playing around with it, but it looks like way more than I want. I basically want to show users a list of things, and let them click a button to buy one. No cart, no shipping, just click a button, connect with Authorize.net (or something similar) to do the transaction, and then display a confirmation page.
Any suggestions or online tutorials people have found helpful? Even perhaps a tutorial in another language. Or maybe a really lightweight Django plugin that doesn't try to do everything like Satchmo? I've been coming up with very little so far.
Thanks!
I did some research recently that may be of interest. Basically, I think Satchless is the most promising right now.
I haven't used it, but Lightning Fast Shop is a Django-based alternative to Satchmo, which is supposed to be pretty lightweight and so might fit your needs a bit better.
