i have an Educational website and i create always pdf files from my learning and ad them for download
but there is many learchers that download my files and reupload them somewhere else
i used google dmca but is there any way to Prevent from re-uploading my files?
One way is to use your .htaccess to prevent hotlinking, but even if you do that, you'll again have the problem that when someone views the document via an in-browser extension (e.g. Adobe Reader, Foxit PDF Reader), they can save it and you've lost control over what they can do with it. Or, depending on how you've set up your site, they can simply directly download it, leaving you again back at square one.
Hence, the solution is to bypass direct access to the document. And, there are a number of ways to do that, which varies based on technique and web software (platform) used.
However, since you didn't mention a particular platform or technology: you can use web controllers (MVC type controllers) to broker the dynamic viewing and displaying of the documents in tandem with a client-side tool / plugin to do the displaying for you (much like Scribd).
However, Scribd uses a proprietary Flash PDF viewer called iPaper, and while it isn't available for use, you can find many other alternatives on the web. One that comes highly recommended (there's even a tag on SO for it) is FlexPaper, an open source plugin that implements a client-side web-based PDF viewer - which I think will suit your needs perfectly (from here):
This project provides a light weight document viewer component
enabling PDF files to be viewed without having any PDF reader software
installed. This project provides both Flex library and stand-alone web
version.
Here are some demos of it in action:

Sorry, by mistake posted partial comment. Anyway...
Why do you afraid of reuploading of your files ? Put links to original site into the PDF and get profit of this. More copies, more downloads, more popularity for your resource. If you indeed would like to make PDFs available from your site only, you have to hide files from users and provide some functionality to read them from your web site only (you can use existing sites of this type). That makes duplicating of your resources to be harder task, but be ready that many users reject to read it this way.

I've published a WPF app to the Microsoft Store. While it generally runs find I do find that some functionalities are missing. For example - I'm using TaskbarItemInfo to indicate stats on the Taskbar icon but it doesn't seem to make any effect.
(sample)
Dispatcher.Invoke(new Action(() =>
{
TaskbarItemInfo.ProgressValue = value;
TaskbarItemInfo.ProgressState = pstate;
}));
I did find out that when I go to the path installed by the store (C:\Program Files\WindowsApps...) and copy the content to another folder on my hard drive, everything works fine.
This leads me to believe the problem is around a more restricted permissions for the store folder, but it's only an assumption at this point.
My questions are:
Is there any knowledge or docs around restrictions for store apps?
Is there a way to simulate the store environment without publishing? Feels like trial & error is not very effective
Link to the app (just for reference): link
Is there any knowledge or docs around restrictions for store apps?
Yes, there is a document that lists the things you need to know before you package your desktop application. Here is it: Prepare to package a desktop application.
Is there a way to simulate the store environment without publishing? Feels like trial & error is not very effective
Generally, I'd suggest you create a sideload desktop-bridge package, then deploy and test it in your device first. This should be easier to find out issues than directly upload it to the store.

My blog currently runs Jekyll and the Minimal Mistakes theme, and uses the theme's built in functionality to add the Disqus comments system.
This JavaScript-based commenting system, to me sort of defeats the purpose of having a static blog in Jekyll, considering:
Its JavaScript creates a decisively non-static page.
Comments are not stored with the website.
Comments are stored in some database instead of flat-text files.
My question is, therefore: What is a suitable system for comments that stays as close to the Jekyll philosophy as possible (an ideally runs on gh-pages)?
I found several possible candidates:
Isso is a comments system which is looks similar to Disqus, it works with a SQLite database
Jekyll::StaticComments seems pretty suitable, but it means you have to manually add the comments from emails.
Are there any other options? If so, what would work with gh-pages, and what would work on a self-hosted Jekyll blog?
Here's another solution which is dynamic and uses JavaScript, but doesn't store the comments at a 3rd party provider:
This guy made a static website with Jekyll, but uses GitHub's issue tracker to create his comments.
He uses GitHub Pages to host his blog, and for each new post, he creates a new issue in his blog's repository.
Then, he uses JavaScript to get the issue's comments from the GitHub API and show it on the page.
Here's a blog post which explains how to set this up:
GitHub hosted comments for GitHub hosted blogs
Whether a javascript loaded, externally hosted comment system "defeats the purpose" of a static site is a matter of opinion.
For me, the point is to be able to host the site as entirely static resources, to take advantage of caching, CDN, distributed hosting, etc. I have seen huge advantages to that, and externally hosting my comments doesn't conflict at all.
That being said, it's an interesting question.
Isso (like Disqus) uses JS on the client side and requires server side software (Python based) that you have to manage, so it doesn't seem like this is any closer to your ideal.
Jekyll::StaticComments is in the right direction, but it's not supported on gh-pages if you have GitHub processing your Jekyll site (you can of course generate the static site yourself and then host it on GitHub Pages).
You also need a way for users to submit comments, and then to get those comments into a file that can be used by the generation process (not necessarily via email as you thought though).
So you need to take comments from somewhere, possibly email, possibly yet another third party hosted app (SimpleForm maybe).
And then you need to manually put them into the YAML site, regenerate, then publish, or, you can set up an automated build process for your site, which can pull the user submitted content when available and build and publish automatically.
Other than manually accepting comments through an off-site medium, you're going to deal with something dynamic somewhere.

I'm relatively new to the web development scene, so please excuse any frustratingly obvious questions.
What I've found myself to struggle with is understanding how all the different technologies of web design fit together - how they all fit into the flow of development and their heirarchy.
I understand the basic html,css,javascript flow. HTML defines your structure and content, CSS comes in and then defines the presentation of said content, and finally javascript adds a layer of interaction and defines how the website behaves. Given that, it's easy for me to see how jQuery etc fit into the picture.
As I move towards making more dynamic sites though, I find myself inundated with trying to learn/balance many web technologies and frameworks (django, mysql, sql, innodb, drupal, rails, php, wordpress etc, etc). I realize that some of what i just listed overlap and serve the same function, but that just goes to show my general confusion with the topic. For example, the django example: I understand django is a web framework that runs on python to help you develop web apps quickly, however, the relationship between the server, html, and python is cloudy to me.
Does anyone know of a good source that can outline how all these puzzle pieces fit together (or feel like offering their description of such matters)?
Thanks :-)
I don't know of any resources that explains this the way you're looking for so I'll just add my take. Maybe we can see where I've goofed.
I like to split the technologies into two camps, Client Side and Server Side.
Client Side is anything that runs on or in the web browser on a user's computer, tablet, smartphone, etc. These technologies include:
HTML (for structure)
CSS (for designing the structure)
JavaScript (for making the structure do stuff)
Server Side is anything that requires a connection to a web server and resources on said machine. This may be a web server running on your localhost as a development machine or a server connected to the Internet. These technologies include:
Web server (Apache, nginx, ...) This is what the user actually connects to via www.example.com in their browser
Server Side Language (PHP, python, ruby, ASP.net, ...) This is what provides access to a physical data storage, like a...
Database (MySQL, SQLite, PostgreSql, MongoDB, ...) This is where the data about your website or app is stored
So, in your example a user would connect to a web server, access a file holding a python script that connects to the site's database and then produces the appropriate HTML, CSS and JavaScript to generate a webpage on the browser's screen.
Obviously this is overly simplified and there's a lot more that goes into it but this is it in a general nutshell.
I would also definitely read this post a lot.

Before I start: I know this is a very broad question, but it is the best way I could phrase it, I have searched around a lot and can only seem to find generic explanations. I searched SO and didn't find much. I have also skimmed through some pages in the wordpress codex, and didn't find anything really useful.
I would like to create a simple database driven blog-style website, it will really only consist of stories (their title, date, content, etc), I just began teaching myself web development and my idea of how database driven websites work has proven to be completely wrong. I figured you would always need a file connecting to the database for each article, but the more I read I learn about mark up being generated on request, and so on, so the actual /year/month/day/article doesn't actually have to exist on the server, or that may be wrong, that is why I am here.
As I said I cannot find much on this topic that isn't a generic graphic of a server interacting with a web page. How does one go about creating a database driven website of this style? Are the files/directories not actually on the server but only created on a case by case basis as someone requests it? If so, then why can you type out a complete url and it be there with out throwing a 404? I have a lot of questions, really all I need is a strong explanation of how these sites work, code examples, and so on. Could someone explain how they work or point me to information (recommended articles, examples or books)?
EDIT: Please don't recommend a framework, I want to understand how these sites work and build one myself.
It's actually quite simple. Wordpress's index page calls wp-blog-header.php. That file calls for other files, and those files call for other files. It goes on for some time until all the contents of the page are actually loaded.
The databases come in when you start thinking about having users. Obviously the user information is stored in the database. Beyond that, Wordpress keeps post titles, dates, and other information in the database for easy loading later on.
Comments are also stored in the database. Each comment is associated with a number, and in the database, just like the posts, the dates/times as well as the usernames associated with the comments are kept.
Further exploration in the actual Wordpress files will reveal a lot of interesting features.
You might want to check out Django. It is an open source Python web framework that provides a lot of the functionality you are talking about. It also has a lot of very good high-level documentation with even a free e-book. It is centered a bit more on newspaper type sites than blogging, but most of the same principles apply. If you are new to python and like to use IDEs I would recommend checking out PyCharm. It has tight Django integration and makes for simple project setup and debugging.
Generally speaking, you'll use a framework that will take input parameters (year/month/day/article), run some code to fetch data from the database, and dynamically create the webpage. There isn't an actual .html file sitting on the webserver. One of the most popular frameworks to do websites like you're describing is Ruby on Rails, which makes it incredibly simple to do.

Are there any tools out there which uses Image Recognition(searching, comparing, validating images) as base for automating and testing GUI software.I know ranorex supports it. Are there any better tools?Are there any gotchas in using Image Recognition to drive test automation?
Ok, first of all, I DO understand the previous answers: testing apps using image recognition isn't the best way to test GUIs. But, at the same time, I don't understand why you aren't answering the question in first place. He's asking for tools that work that way, I'd think he's smart enough to understand where he's going into.
Ok, now the main subject, my choice would includes:
Sikuli, a MIT project under the GNU-like MIT license. It uses Python over Jython. Free.
TestPlant eggPlant, a tool that works through a VNC server, so you can test apps in any VNC compatible platform (including smartphones). It has some nice features like OCR, test schedule and so on. It uses SenseTalk. Not free, you could request a trial.
Routine Bot, I've never used it but it seems pretty useful.
I would also discourage using Image Recognition with SendKeys and Click at Coordinates or (Button Images) to do UI testing. I have been recently using UI Automation to automate the testing of a WPF application with success. By placing small breadcrumbs (Automation.AutomationID="OkButton") throughout our application's XAML I have been able to write some C# Unit Tests that exercise different aspects of the application. Even without the breadcrumbs UI Automation is still capable of exercising an application, but it is slightly more difficult when trying to identify the controls on the UI.
A decent article on Code Project is available as a starting point.
http://www.codeproject.com/KB/WPF/UIAutomation.aspx
You will also need UI Spy, a free tool from Microsoft, which helps you find controls and manually exercise the controls through UI Automation as guidance for writing the scripts. The tool is buried in the Windows Vista SDK, after installation search for UISpy.exe. The UI Spy tool can still run on a Windows XP machine by just copying the EXE to the target machine.
Consider AutoItScript for driving Windows-based GUIs in test scenarios - AND scraping off the UIs. Consider tesseract open source optical character recognition. Also OpenCV for machine vision.
Free AutoItScript works at the API level in that you can read states of various Widgets and Windows sections, send actions to these UI components too, wait for state changes etc. It's possible to produce highly robust automation code that will ensure focusing on Windows and resolution independence.
Let me suggestion another solution.
It's not a complete UI automation framework, but rather a specific tool just for the Image validation.
It will allow you to ignore the unstable part of your images as well (random data, etc.)
It will integrate with any other UI testing framework you choose:Selenium, Sikuli, etc.

thanks for your comment! please Take a look at RoutineBot – interface testing software based clicking on certain image patterns and see for yourself how this idea is implemented in an
automation tool!
Old question, but perhaps this answer may prove useful to someone. I currently am using two products,
Testing Anywhere, by Automation Anywhere (http://www.automationanywhere.com/Testing/)
and Quick Test Professional, by HP (http://www8.hp.com/us/en/software-solutions/software.html?compURI=1172957#.UhJBwpLW5-k)
Both of them do the job well enough, and both support the use of image recognition. I am not entirely convinced that image recognition is in itself a bad thing. As with all things, you have to tailor your approach to your particular needs and use the right tool for the job.
Just thought I'd add another entry to this thread. Things may have changed, not sure, but when I last saw the demo, this product offered Sikuli-like IDE/interface/capabilities while being a commercial product and supported actual devices beyond simulator. Don't know if the tool has improved to detect objects by identifiers beyond images now or not.
