i got the SDN4 - university example from here
https://github.com/neo4j-examples/sdn4-university. We could run the project and test it. There is this authentication code in the angularjs front end code, but the back end api is not available for the same. Is it available somewhere?
It hasn't been implemented yet (though a PR is welcome)

I've just started learning Django and from the first tutorials i've followed or test i've done, it seemed to me (note: i'm a beginner at the whole web developing thing) that you can use it to do anything (back end as well as front end). Now thinking about the many frameworks and libraries for the front end I thought that I was missing something, so after a bit of research i came to the conclusion that the back end part is there only to provide a rest service to use with a front end framework. Do anyone for example uses the templates in Django, if so for what purposes?
Am I missing something about front end - back end integration?
Thanks.
I don't know where you got the idea that no-one uses templates in a back-end framework. Of course we do. The vast majority of sites do not use front end frameworks. Even today the idea of rendering everything in Javascript is controversial - see here for a whole range of reasons why it may not be a good idea.
Most sites don't need that level of interactivity, anyway. StackOverflow (although it's done in .NET, not Django, but the concept is the same) is a great example: the bulk of the work is done on the back end using templates, and Javascript is used to add enhancements in the browser, not to do the whole work.
If you're only interested in providing a RESTful webservice, then you'd be better using a lightweight framework, like flask. Django provide much more, it comes with a good template system, with well-defined and easy-to-implement models, with powerful routing capabilities, that help you build a website from scratch very fast.
This doesn't mean that you cannot build a RESTful API in Django and use a SPA on the presentation layer.
To answer your question, it all depends on the design of your website. If you're planning to develop a public website that has a lot of content and you want it to be indexed by search engines, then using the Django routes and views helps you accomplish this (not that SPA's can't have SEO, however it's a little bit complex for them).
I'm just getting started with EmberJS and saw the "routing" example on the emberjs.com page. It takes the form of a mail client.
I've downloaded all the files (app.js, application.hbs, etc) but can't figure out how to get it to "work".
There seems to be missing an HTML as the entry point?
OR, if nothing is missing, how do I view this app within a browser?
Unfortunately, although this example makes its point (showing how you don't need a lot of code to do something that is traditionally complicated), you can't use the files directly without some tooling to compile the templates, for instance.
It is recommended for any new Ember project to use Ember CLI to do this work for you. You should check out the 'Getting Started'-section of their website, and then read through the section on using modules and the resolver, which will explain the ways in which the example you are looking at would be different.
The official Ember Guides are very good for getting started, and I'd recommend you check that out (make sure you read that modules-part if you're using ember-cli (which you should) before you go through the guides). Also, please join us on IRC on #emberjs if you have any questions that would need some more back and forth.
Welcome!
Delphi used to include a demos folder for web Services, but no longer seems to include this.
I just tried the Delphi 7 demo projects (SOAPDMServerWAD, a server with almost no UI at all, and SOAPDMClient) and was unable to get them to function, even in Delphi 7.
If anybody has ever made a similar demo work in Delphi XE, or Delphi 2010, identical to the old SOAPDMServerWAD+SoapDMClient demos, working in Delphi XE, and with at least the minimal UI that comes from the Delphi SOAP Server application wizard, that would be perfect.
Update: The demo appears all the way up to Delphi 2010 but uses the now-obsoleted WAD (web-app-debugger), I tried to port it to the new Indy runtime/web-app-development-harnessing-code, but I can't seem to get it working. The demo runs, but the server has no User interface, and does not appear to be running any HTTP server (tested using a regular web browser, via http://localhost:port/ urls. By the way, try googling for a demo, and this url comes up, and I asked less than an hour ago. That's scary, google.
Update2 See my own answer below, a link is coming soon with working code.
I have posted the complete set of demos for SOAP on CodeCentral as item 28789.
These contain every single one of the Delphi 2007 era SOAP demos from the WebServices folder, now updated for Delphi XE and XE2, including converting the old WAD servers into new INDY VCL servers. You'd think that was impressive, except it's not. It's really easy. Just use the wizard to create a new project, and then add the web service interface and implementation units, and any other units that belong in the old demo, to the project. Once they're added to the project, they just work. Basic demo SOAP Servers are really easy to build in Delphi, once you have a working demo, you'll find it's pretty easy to modify and extend it.
The demo that best answers the question I asked above is in the SOAPDataModule sub-folder.
The basic problems with the demo from the 2007 era are two:
The WAD (web app debugger) is gone. you have to make a new server using the Indy server, for optimal demo purposes, saving you from using WAD (which is gone) or setting up ISAPI environment, under IIS, which is hardly ideal for demo purposes. The new demo project I made is called SoapDMServerINDY, and it consists of a data module (datamod_u.pas), a VCL form User Interface unit (IndyServerVCLFormUnit.pas) and an Indy Server web module, called IndyServerWebModule.pas.
The Delphi 2007 demo broke thanks to the new practice of having a Debug/Win32 subfolder that the demo executable is now in, you need to go up further. I fixed the demo server so that it warns you with an error message if the data files cannot be located, saving you from the mysterious "XML parsing error". I also added some error checking in a few of the demos so that it tells you that you need to install interbase for this demo to work, since some of the demos require Interbase installed and running, and one requires an alias called IBLOCAL to exist, and preferably a table called EMPLOYEE to exist.
The elements of this demo are a server (SoapDMServerINDY, based on the code from SOAPDMServerWAD), and the client SOAPDMClient which connects to the demo and has two pages, one page will show basic data access via a DBGrid + dataset remoting, and the second page shows how to invoke a custom SOAP method.
To use the demo: You have to start the server, click the start button, then start the client and click Connect.
Hello all CodeIgniter guys :), I'm new to CodeIgniter andIi have now put my project on github. Here is my github page: https://github.com/SimonJ/Hip-hop-project
So I would hear about someone bothered to look through my files and make comments about what I can do better so I can learn something new :)
I have tried to use ocular template system but I get this error:
An Error Was Encounter Unable to load the Requested Class: ocular
Do you know what I'm doing wrong?
This question borders on the edge of belonging on Code Review instead of Stack Overflow, but I'll help you with your templating issue.
Are you running PHP 5 on your server? It looks like Ocular is using "public" and "private" words for functions and variables.
You are running an older version of Codeigniter by the looks of it because I don't see a folder called "core" in your application folder. There's a community version of CI called Reactor here or you can get the standard CI 2.0 from EllisLab here. I would upgrade to one of those, personally I would use Reactor.
Ocular is great but Phil Sturgeon has a lighter template library simply called template you might be interested in looking at as well, here. Like I said in the first paragraph of this answer, go to Code Review if you would like to have your code critiqued and reviewed.
PS. Welcome to Codeigniter, it's an awesome PHP framework.
We develop custom survey web sites and I am looking for a way to automate the pattern testing of these sites. Surveys often contain many complex rules and branches which are triggered on how items are responded too. All surveys are rigorously tested before being released to clients. This testing results in a lot of manual work. I would like to learn of some options I could use to automate these tests by responding to questions and verifying the results in the database. The survey sites are produced by an engine which creates and writes asp pages and receives the responses to process into a database. So the only way I can determine to test the site is to interact with the web pages themselves. I guess in a way I need to build some type of bot; I really don't know much about the design behind them.
Could someone please provide some suggestions on how to achieve this? Thank you for your time.

Check out selenium: http://selenium.openqa.org/
Also, check out the answers to this other question: https://stackoverflow.com/questions/484/how-do-you-test-layout-design-across-multiple-browsersoss
You could also check out WatiN.
Sounds like your engine could generate a test script using something like Test::WWW::Mechanize
Usual test methodologies applies; white box and black box.
White box testing for you may mean instrumenting your application to be able to make it go into a particular state, then you can predict the the result you expect.
Black box may mean that you hit a page, then consider of the possible outcomes valid. Repeat and rinse till you get sufficient coverage.
Another thing we use is monitoring statistics for our service. Did we get the expected number of hits on this page. We routinely run a/b tests, and I have run a/b tests against refactored code to verify that nothing changed before rolling things out.

I can think of a couple of good web application testing suites that should get the job done - one free/open source and one commercial:
Selenium (open source/cross platform)
TestComplete (commercial/Windows-based)
Both will let you create test suites by verifying database records based on interactions with the web app.
The fact that you're Windows/ASP based might mean that TestComplete will get you up and running faster, as it's native to Windows and .NET. You can download a free trial to see if it'll work for you before making the investment.
Check out the unit testing framework 'lime' that comes with the Symfony framework. http://www.symfony-project.org/book/1_0/15-Unit-and-Functional-Testing. You didn't mention you language, lime is php.
I would suggest the mechanize gem,available for ruby . It's pretty intuitive to use .
I use the QEngine(commerical) for the same purpose. I need to add a data and check the same in the UI. I write one script which does this and call that in a loop. the data can be passed via either csv or excel.
check that www.qengine.com , you can try Watir also.
My proposal is QA Agent (http://qaagent.com). It seems this is a new approach because you do not need to install anything. Just develop your web tests in the browser based ide. By the way you can develop your tests using jQuery and java script. Really cool!
