I would like to integrate a "virtual blackboard" functionality with my e-learning website. I would like users to be able to participate in "meetings", with the following functionality:
chat (optionaly voice chat/videochat)
virtual blackboard (collaborative drawing)
screensharing (so one of the users can present material like pictures to other users)
ideally Flash or Java applet based (so users wouldn't have to install any additional software - but this is not a requirement, as long as setup wouldn't be too cumbersome)
I guess there are no free solutions, so I'm looking for a paid one. It would be best if users didn't have to set up separate accounts to participate in meetings. Perhaps they could just click on a link with the meeting id.
I googled a little and looked at Adobe Connect Pro. Are there any alternatives that you can recommend?
Checkout BigBlueButton http://www.bigbluebutton.org/
BigBlueButton is an active open source
project that focuses on usability,
modularity, and clean design -- both
for the user and the developer. The
project is hosted at Google Code
http://code.google.com/p/bigbluebutton/
It's not hard to create one with only JavaScript. Then the user really doesn't have to install anything, unlike with Flash or Java.
A pretty good tutorial is here, and additionally Ajax: The Definitive Guide has a good tutorial around Ch. 20 ish.
Influxis also has some Flash based meeting software apps and gives you the source code, so that you may extend them, if you are interested in that.

I want a simple html and javascript based web page for editing a single document for documentation of an app that I am making. it should be editable by multiple people if possible asking for a password before it registers. I have ftp access to a web site but that is it. no database. I did not find anything that will point to a single file and just simply edit it without any software requirements. it would be nice if it were mobile friendly too.
I work for a hosting provider so that is a good question imo. What you are looking for is a flat file storage CMS to avoid a database. Requiring user management and simplicity you will not want to code this from scratch. We deal with alot of CMS (Content Management Systems) and most are bloated and require MySQL.

I fired an installation up and it is very easy to install, has alot of features, and is very WordPress like which means it looks good out of the box and is very easy to use.
I hope this helps you out and if you do use it let me know your thoughts.

all. Anyone have any readings, guides, tutorials, or resources that they particularly recommend for RSS -- especially for going about the task of building an RSS reader?
Seeing as my question landed with a thud, I thought I'd share what I found myself from a little digging, for whoever comes along next.
First off, there are the tutorials offered at http://www.w3schools.com/rss/. The stuff from W3C is always useful, in my experience.
I also offer up this list of books and guides that are either about RSS directly or discuss it at some length:
RSS and Atom in Action: Web 2.0 Building Blocks (Manning)
Java and XML (O'Reilly)
Beginning Java Server Pages (Wrox -- includes a discussion of Java's ROME framework)
Developing Feeds with RSS and Atom (O'Reilly)
You can tell from the above that I was searching specifically for RSS as it relates to Java. But I also found resources about building RSS readers with Python and PHP. Of course there is lots more out there relating to Android, iOS and the like.
I hope the above will be helpful, but if anyone has any further and better resources, how-tos, and guides they recommend, please add them. Thanks!
According to what i have gathered so far,there aren't many resources on rss readers.Apparently readers use polling to track updates.issues of etiquette have emerged in all articles i have come across but none of all articles explains it like this post:
policy for polling rss

Given that Sql Server Reporting Services is designed to be open and extendable, and that the bundled Report Manager isn't that great, are there any alternative open-source SSRS Front-ends out there?
By 'front-ends' I guess I mean web apps that can display the available reports on the reports server, gather the required parameters (hopefully in a more flexible way than Report Manager) and then run the reports. I'm imagining things that are built using the Asp.Net ReportViewer component, but have better parameter gathering.
I've found one on CodePlex: reportviewer.codeplex.com (edit: actually, this looks like a winforms solution, but its the closest I've found) ... but I'm wondering if there are others out there, cos this seems like an area in which lots of people have had to 'roll their own'.
To answer my own question: There didn't seem to be any alternative open-source SSRS Front-ends out there, so I have built one and open-sourced it:
CrissCross at Github
You point it at your SSRS server and then off it goes - it can display the report catalogue and lets users run any report. So far I've optimised it towards reports with lots of optional parameters and lots of multi-picks, but it should be able to handle any SSRS report. And if it can't, you can get stuck into the code and change it.
The main difference to the standard SSRS Report Manager is in the presentation of parameters: CrissCross is more ajaxy, and (being open-source) more customisable.
See the github site for more details.

I have learnt most of the main skill points in ASP.NET model, eg how to use a GridView. I would like to find some complete website with source code to analyse/observe, but so far it seems on the internet most learning resources are dealing with a specific topic. Is it possible to find some?
There are lots of open source asp.net websites out there.
See this list from the Microsoft asp.net site, in particular the starter kits and samples section.
I suggest you download and install the free Web Platform Installer from Microsoft. In the tab Web Applications you can find a lot of ready made applications to learn from.
Check out this video: http://www.asp.net/general/videos/build-your-first-asp-net-application-with-asp-net-web-forms
It explains well where to start and how to create "Hello World" type of application.
Don't bother with Web Platform Installer/other advanced starting kits because they are too complex for someone new with the platform.
There seems to be a lack of sample asp.net websites with available source code. Note an open-source website does not mean you can obtain the website. You may have to buy the website to view the open source. However I did find a large number of real-world websites with available source code in Chinese.

I am aware of a tool which MS has provided which tells you about coss site scripting attack etc.
The tool is http://www.microsoft.com/downloads/details.aspx?FamilyId=0178e2ef-9da8-445e-9348-c93f24cc9f9d&displaylang=en
But are there tools which you have used for ASP .NET applications which do similar to this and which one is widely used in ASP .Net applications ?
Unfortunately CAT.NET is as good as dead so you can rule that one out.
In terms of XSS detection, if you're wanting to test vulnerabilities in an existing app you need not constrain yourself to static code analysis or .NET specific tools. There are plenty of language agnostic scanners out there you can run against the URL of an existing site.
One I've found very useful in the past is Netsparker from Mavituna Security. This is really easy to get up and running with (download it, enter a URL in a nice UI, run the scan) and the results are easily interpretable. You can grab a free community version which will identify persistent and reflective XSS (among other vulnerabilities) or pay for a licensed edition with a heap of additional features.
Are you thinking of the Web Protection Library?
