My boss wants me to write a simple RSS feed for an C++ MFC app that will pull and display information from the company's website. It also must be able to grab program updates from the website, tell the user that there are updates and then install the updates. Are there any tutorials that follow these guide lines? How would stackoverflow.com implement these requirements? Libraries, tutorials or guidance would all be great!
RSS is not more than XML (Ref). Under Windows/MFC you can use MSXML directly or use this MSXML wraper class, tinyxml, or other any other XML library to handle XML.
Update:
To download RSS you can use CHttpFile.

Can you tell me how can I make a program that automatically downloads an XML of an URL and takes it's titles, ddescription etc.. If you can recommend me a good API or library, please give me and a link to tutorials how to use it. :)
You can use the cross platform libcurl to easily download webpages through http (and various other protocols).

I have basic website I developed in Django and SQL lite.
I want to add this feature to it.
A user should be able to click a button and record a message that is no longer than 10 seconds and save it.
It can be saved on server as an audio file or can be saved on the database if that is more efficient and possible.
Can you please let me know if Django already has any component or plugin or something that I can use?
If it doesn't exist, what are my best options. If I need to write from the scratch, can you point me to any tutorials/blogs, etc?
Thanks for your time

As far as I know there's no such plugin for django. But it's not mainly django's work to do this. You can record audio via javascript using Web Audio API, or by using one of several projects (see this answer). Also if you have to support older browsers I think that your best bet is to use flash for this purpose (but some mobile browsers don't support it). So the best thing is to use some sort of fallback mode with html5&javascript implementation for browsers that support Audio API and use flash for others.
My situation: I'm working on a web monitoring dashboard that assembles informations from different applications and sources and generate graphs, info graphics and reports.
The applications I'm trying to integrate are CACTI, Nagios, and other local private monitoring tools. I had no problem to integrate these applications, except for Nagios (I don't have much experience with it).
What I want to know is if there is a way to use Nagios as a Web Service, or something similar, so I can expose some of the informations and use it to generate my own reports on my dashboard application.
Is it possible to do that without any epic effort?
thanks for reading.
Nagios 4.x starting with version 4.4 now includes CGIs for JSON output. Installing the newest version of Nagios might be the easiest way to go.
See the announcement here.
Review the slides from Nagios World Conference 2013 here.
The Check_MK Multisite GUI (Web base GUI using MK Livestatus) offers a web service mode, where you can send queries/commands as URL parameters and get the response as JSON in the body.
The trick is: Create a view in the GUI, which fits your needs. Then extract the URL of that view and add the parameter output_format=json. Now you should have the output in a parsable format.
For example, this URL should give you a JSON list of all services:
check_mk/view.py?view_name=allservices&output_format=json
You can try:
1) MK Livestatus http://mathias-kettner.de/checkmk_livestatus.html
it's not web service but it can give current data without any complicated action. All you need redirect this data.
2)status-json plugin http://exchange.nagios.org/directory/Addons/APIs/JSON/status-2Djson/details which return data in JSON format.
3)NagiosWS plugin but I wasn't able to get to work it yet. I think it can be done for Nagios 2.x
4)GroundWork Foundation plugin. I think I will try use it now.
I was able to get to work 1 and 2 solution now.
Otherwise you can use Icinga which can give you some JSON or XML output. Icinga is fork of Nagios and can be installed with saving all your nagios data and plugins. At least it written on Icinga's site =) They have some other solution like PHP lib.
Sorry, I cannot post only 2 link while I'm newbie on this site.
Best regards.
Worked for me - MK Livestatus http://mathias-kettner.de/checkmk_livestatus.html it's not web service but it can give current data without any complicated action. All you need redirect this data.
Does anyone know if there is a help authoring tool out there that can produce help documentation for a software product that looks like a wiki? We are currently using the Confluence wiki engine, which is absolutely brilliant and we were wondering if there is anything like that but without the need for an Apache server. Something stand-alone that can give our users the help documentation they need. We have used help authoring tools and they all seem so clunky compared to a wiki.
Use Wiki on a Stick.
Its a single .html file written in Javascript/html and saves the changes onto itself.
You don't even need Apache. Awesome tool!
How about Juli? It generates static HTML so you can browse documents by browser only.
It is used for:
Juli documentation itself.
Edgar project documentation (another my OSS project).
My personal wiki/blog. I'll show later since new users can only post two links(stackoverflow limitation)
Our company has a set of 3d modeling softwares written in c++ with qt based gui. We are planning to offer these applications to customers to try them from a web browser. I mean to say, we need to create web interfaces for native c++ codes. Please suggest me which technology, languages should be used. If possible please give some links to some white papers or case studies for this kind of projects. I am totally clue less :)
Ideally you would keep your c++ code on the server and use a mixture of HTML and Javascript on the browser. However since 3d modeling is so client centric you may have to run some c++ code directly in the browser.
There are a few options to look at:
Emscripten
Adobe Alchemy
Google Native Client
A Java Applet using NestedVM
Netscape plugin API
ActiveX
You could also run a few instances of your application on your server inside an XVnc session and let people use it through a VNC viewer applet. The simplest solution however is still to offer a downloadable demo of your application.
Have a look at Wt
Take a look at Native Client.
Soon you might be use WebGL to do 3D in the browser. But how long it will take for browsers to include it I do not know. But it might be good to look at it to not rule out using it in the future.
If creating everything again is too expensive, always you can create a distributed application:
One program running the main application in C++ and generating (for example) XML files.
A web application reading the XML files generated by the C++ application and translating them into the web application language (for example Adobe Flex).
Good luck!
