Where can I find a Qt tutorial in PDF format. I have looked all over google but can't find one. I need to be able to read it offline as I can't always be on the internet. Thanks!
If you're looking for a tutorial or a book, rather than QT docs have a look at this free ebook :
C++ GUI Programming with Qt 4
The author has released the first edition with an open license. If you like it You can still buy the printed second edition in amazon.
There is no PDF directly from trolltech that I know of, but all of the docs are under
Qt\200x.xx\qt\doc\html
where 200x.xx represents the version of the Qt SDK. Mine is 2009.01 for example.
You could use one of many HTML to PDF converters to achieve what you're looking for.
You can actually use an html to pdf converter created with QT... http://code.google.com/p/wkhtmltopdf/
am i too late?
you can also use an html spider that downloads an entire website.
The second edition is also freely available (but only in HTML format):
C++ GUI Programming with Qt 4, second edition. Click the Sample Content tab to access them. The chapters are all there (but in the wrong order---however, the table of contents is listed at the bottom of the page so you can see the correct order). All the examples are available from the Downloads tab.
A more advanced book is also available (but it is not free): Advanced Qt Programming

I'm very new in building web application using ember.js. I went through the ember.js official guide and found ember.js is very much interesting. I have learned the basic structure of ember.js. But I need a tutorial which will help me to go through building a complete web application using ember.js describing different part of its development process. That may be in document or video tutorial. Please help me to find out the best tutorial to learn ember.js.
You can find a lot of material on EmberWatch, I'd suggest starting with the one which considered to be the official guide by Tom Dale.
I think we are yet to discover complete Ember.js tutorial, nevertheless you can use these resources to help get you started.
I would definitely start with Official Guide
If you do not want to use Ember Data which is still in early stages you can read this blog
A lot of useful information have been presented on EmberCamp 2013
If you want to see real world application source code, check Discourse

My company wants users to be able to gather different documents from our website (for instance, manuals, installation instructions, etc) and put them all in one place (kind of like a shopping cart) to then print out all at once when their visit is over. Are there any applications that I can leverage to do this? We want something that's fairly plug-and-play because this is a late-stage requirement. I feel like I've come across something like this before but can't remember where.
Any suggestions would be greatly appreciated! Thanks!
There should be scripts where it bunches all of the selected documents into a zipfile for you. I've seen it on Joomla sites where you select different modules you want to download and it puts it into one package. Sorry I can't help with actual code.
You say "shopping cart" but are users paying for these documents?
If so, you can outsource the downloads to a third party like PayPal to handle the digital downloads. PayPal API will let you handle a shopping cart.
If not, why not just have a link to a PDF on the document's description page? Then they can save, print, whatever. (My two cents, of course, but I don't see the big advantage to bundling a bunch of documents just to unbundle them on the other end.)

Is there some flowchart diagram tool that would (or could be made to) integrate with a self-hosted wiki?
Requirements:
basic functionality (e.g., drawing some boxes and some arrows)
would strongly prefer it to be visual (i.e., not written out in text that then gets converted)
allows for dynamic editing
it is important that the tool can be integrated into the wiki (e.g., as an extra panel somewhere)
can be run from a personal server
free
I've looked around at other threads here concerning a diagram tool, but they are either desktop applications, online ones which reside on third-party servers, or cost money.
[Edit] Thanks for the responses, but I would like them to be dynamically editable (I've added this to the requirements). What I mean is that I would like to integrate (or run it from a private server) some online collaborative diagramming tool. While I could create a JPG of something made in Graphviz and upload it, this is not easily editable. I would have to upload the source file somewhere, which someone would have to download and edit, then upload the new JPG.
Graphviz dot diagrams can be embedded in some wikis. Unfortunately for your requirements, it's text that gets converted. It's fairly simple to learn and use though.
http://www.graphviz.org/
EDIT: It's free / open source.
I've been looking for something similar - collaborative flowcharts in a wiki. The most interesting so far is this Mediawiki extension: http://www.flowchartwiki.org/wiki/index.php/Main_Page
Balsamiq Mockups for XWiki is the closest thing I've seen. It's more of a previsualization tool however for application mockups, though I'm not sure if this is the kind of tool you're looking for.
It is free if you qualify under their licensing.
Another option would be using Mediawiki with the Dia extension.
I like using the svgedit plugin in dokuwiki for quick diagramming on the run. It produces standard SVG text files and has an always up to the date javascript wysiwyg editor. And, I submitted a bug/feature request on github and the requested functionality was added post haste.
Edit: FOSS!
i understand this question is old enough. but you could try Origramy. it's a Flash-based visual tool. and XML as the result can be get from the component. alas integration to wiki must be made separately
Not sure of the technology you have on your server, but Open Diagram can create a jpg image file on the server which can then be referenced as a normal image in your wiki. Its open source.
I've enjoyed the simplicity of UMLet for a while as a desktop app. Don't let the name fool you! There is more than just UML - it has a lot of basic charting elements in it. It's not pretty, and it can be awkward sometimes, but it works. Has basic visual items in a template/toolbox that you double-click on to reproduce on your canvas. You can then move it about, resize it, or edit the item and modify it via text.
There isn't an existing online integration method (that I've seen), but being that it's good old fashioned java, you might be able to make it happen.
It's free and distributed under the GNU General Public Licence.
honestly i think you are going to have to use Java and code an applet. there are wondrous advancements in javascript libraries (AJAX, JQuery) that also might assist in this...
cheers my friend.

Ok here it goes, hope this is an original idea. Scenario is this. I have hosted a personal website, which contains a wordpress blog as well. I have a windows mobile connected to internet via GPRS.
I want to write an application for my windows mobile, which would track my current GPS coordinates (I don't have GPS but have figured out a way to find out the coordinates), and upload them to my site, where I'd provide a web service which can get or set GPS coordinates. Then I want to display my current location in my blog (as a wordpress plugin) or in another page, where it talks with my web service again to obtain my latest GPS coordinates.
So am I reinventing the wheel or there's a complete solution available for me to achieve such a thing?
Any pointers please. It's not directly programming related, but it sure involves programming!!!
Sounds like Google Latitude.
There are quite few of these types of applications/systems.
I myself have written a similar system to try to recover my phone if it gets stolen.
On codeplex you can find This (not mine).

Does any body know what powers Google Charts? I have been using it for a while but not sure what Google used to build it.
They bought the Gapminder library for doing charts. It's a Java library as far as I know, but they don't seem very anxious to release the code as open-source.
Everything at google is done in C++, Java, or Python. I'm guessing the internals is probably done in one of the latter two.
Mathplotlib was my guess too - ( thanks "davidg" ).
SVG - got my own doubts because you don't have to go the length of server side SVG just to produce a static image. No panning or scaling required so not sure if they used SVG
I feel the touch of SVG there..
Maybe Internal engine to generate and work with SVG and export images as PNG images.
Any other thoughts?
Just guessing here: they must be using Python with some charting library and then returning the produced files. There are a few tools to do charts in Python. Matplotlib and ReportLab come to mind.
What is sure is that you can do it with a Java servlet.
Eastwood is an open source implementation of the Google Chart API.
(powered by JFreeChart)
Probably just libraries they have written themselves, it's pretty easy to throw together a chart drawing library, but hard to do it right. So someone hacked together a custom java/C++/python library using already available stuff to be able to update the graphics of his charts easily, and then it extended.
That's the great thing about it, that you can make your own version without much effort, just change the URL and design your own flash animation of the chart. And that the data available in the graphs is easily webscraped..
Just theory, but something like this is perfect small project to do in 20% of your time.
