There are some guys at Mozilla working on implementing a PDF reader using HTML5 and JavaScript. It is called [pdf.js][1] and one of the developers just made an interesting [blog post][2] about the project.

There is an open source HTML5/javascript reader available called Trapeze though its still in its early stages.

Demo site:

You can use the [Google Docs][3] PDF-viewing widget, if you don&#39;t mind having them host the &quot;application&quot; itself.

I had more suggestions, but stack overflow only lets me post one hyperlink as a new user, sorry.

Well it&#39;s not even close to the full spec, but there is a [JavaScript and Canvas based PDF viewer][1] out there.

I have a `PreferenceCategory`, xml file and I have defined all preferences in it, I call this from class that extends `PreferenceActivity`. I am unable to set the background of my settings screen, this screen is displayed with help of xml file shown below. Please see that I have already defined the `android:background=&quot;#041A37&quot;`, still the screen remains default color: black.


    public class MyPreferenceActivity extends PreferenceActivity {
        @Override
        public void onCreate(Bundle savedInstanceState) {
            Context mContext=super.getBaseContext();
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.layout.preference);
            //v.setBackgroundColor(Color.rgb(4, 26, 55));
        }
    }

Although I have set `android:background=&quot;#041A37&quot;` in every file, the background doesn&#39;t turn into navy blue, or any other color for that matter. It remains default color, black. How to change the background color. Please let me know any pointers / hints , if you had faced same issue let me know what changes you made to set the background color.

I am currently writing my first Android application and I keep running into references to background and foreground services. Since I intend on using a service in my application I was hoping to get a clarification between the two and how they are used.

What is the difference between a background and foreground service?

Is there any open source Javascript based PDF Viewer available? Any guide to developing this kind of script that renders PDF docs would be helpful.

I am encoding a string that will be passed in a URL (via GET). But if I use `escape`, `encodeURI` or `encodeURIComponent`, `&amp;` will be replaced with `%26amp%3B`, but I want it to be replaced with `%26`. What am I doing wrong?

URL encode sees “&amp;” (ampersand) as “&amp;amp;” HTML entity

I have an `input` field that saves a URL, I&#39;d like this saved input to recognize when &quot;Http//&quot; is absent from the start of the variable but have no idea where to begin... is it possible to check only a portion of a string? - then have a function that will append if necessary?

How to **trigger a JavaScript function when someone selects a given text fragment** on a page using mouse?  
Also, is there any way to **find the position of selected text** on the page?

Update:
To be more clear, text fragment  can be part of a sentence or a word or a phrase or whole a paragraph.

The old JS SDK had a function called FB.ensureInit. The new SDK does not seem to have such function... how can I ensure that I do not make api calls until it is fully initiated?

I include this in the top of every page:

    &lt;div id=&quot;fb-root&quot;&gt;&lt;/div&gt;
    &lt;script&gt;
      window.fbAsyncInit = function() {
        FB.init({
          appId  : &#39;&lt;?php echo $conf[&#39;fb&#39;][&#39;appid&#39;]; ?&gt;&#39;,
          status : true, // check login status
          cookie : true, // enable cookies to allow the server to access the session
          xfbml  : true  // parse XFBML
        });
        FB.Canvas.setAutoResize();
      };
    
      (function() {
        var e = document.createElement(&#39;script&#39;);
        e.src = document.location.protocol + &#39;//connect.facebook.net/en_US/all.js&#39;;
        e.async = true;
        document.getElementById(&#39;fb-root&#39;).appendChild(e);
      }());
    &lt;/script&gt;

How can I inspecting PDF files, preferable with a tool?

Use case: I&#39;m trying to programmatically generate PDF files (using iText).  I&#39;m having trouble achieving certain layouts, but I have PDF files with text laid out the way I want (generated from Word).  I would like to reverse engineer how they do it.

[PDF Inspector][1] seems to be good, but I&#39;m looking for something for Windows.

Hey, for quite a while now, I am looking for a pdf viewer for the command line.

As I like to work without X on Linux, and often work on a remote machine, I would like to have a tool to read pdfs. There are quite a lot of really good graphical programs (evince, okular, acroread, ...) to do the job, so I figured there should be at least one decent text-mode tool. But I don&#39;t even know of a crappy one!

Currently, I either start X only to read pdfs, or use pdftohtml+lynx.
However, the latter does not produce a very good output, and most documents are just unreadable, especially if they contain mathematical formula.

Google is full of people saying either it&#39;s not possible or suggesting the pdftohtml version.

I realise, this is not exactly a programming question, but I am currently considering starting a project to implement such a program, unless there already is a good one out there.

Thanks for any suggestions.

I want to merge many PDF files into one using [PDFBox][1] and this is what I&#39;ve done:

    PDDocument document = new PDDocument();
    for (String pdfFile: pdfFiles) {
        PDDocument part = PDDocument.load(pdfFile);
        List&lt;PDPage&gt; list = part.getDocumentCatalog().getAllPages();
        for (PDPage page: list) {
            document.addPage(page);
        }
        part.close();
    }
    document.save(&quot;merged.pdf&quot;);
    document.close();


Where `pdfFiles` is an `ArrayList&lt;String&gt;` containing all the PDF files.

When I&#39;m running the above, I&#39;m always getting:
    
    org.apache.pdfbox.exceptions.COSVisitorException: Bad file descriptor

Am I doing something wrong?  Is there any other way of doing it?

How to merge two PDF files into one in Java?

Can anyone recommend a library/API for extracting the text and images from a PDF?
We need to be able to get at text that is contained in pre-known regions of the document, so the API will need to give us positional information of each element on the page.  

We would like that data to be output in `xml` or `json` format.  We&#39;re currently looking at *PdfTextStream* which seems pretty good, but would like to hear other peoples experiences and suggestions.

**Are there alternatives (commercial ones or free) for extracting text from a pdf programatically?**

I&#39;d like to use PDF versions of my matlab plots in a LaTeX document. I&#39;m saving the figures using the &quot;saveas&quot; command with the PDF option but I get huge white space around my plots in the pdf files. Is this normal? How can I get rid of it? Automatically, of course, since I have &quot;a lot&quot; of plots.

I have been reading through the backlog of answered questions on SO regarding &quot;How to promote an open source project&quot;. Not surprisingly, many of the answers pointed people to SoureForge/FreshMeat and other sites etc as well as blogging and whatnot. This started me thinking where is the best place to host a project and why?

As my first project is currently hosted on CodePlex, I started to wade through the Google search results to collect information on the pros/cons of each; however the comparisons that I found are rather dated (2+ years old). 

http://www.stum.de/2008/12/13/sourceforge-vs-codeplex/  
http://www.developmentnow.com/blog/2006/11/codeplex-vs-sourceforge/  
http://www.spacesocket.com/forum/thread-6654.html  
etc...

So the next question becomes &quot;Should I host my project on multiple sites&quot; to which the following post provides the expected answer (thankfully! as that would be a pain to maintain).

https://stackoverflow.com/questions/536528/hosting-an-open-source-project-at-several-sites

Based on the current state of various Open Source hosting sites such as CodePlex, GitHub, Google Code, SourceForge, etc, etc is there any notable pros/cons of one site over the other? i.e., should I stick with CodePlex or am I missing out by not using one of the alternatives? Will one bring about more traffic to a new and unknown project?

I plan on exploring each site in more detail to see what they all offer, but given the vast knowledge of the good folks on SO, figured I would start with this question first.

**UPDATED**

As per erjiang answer below... I am currently using Mercurial for version control, and I am open to anything other than TFS. Also, my current project is only me developing, but future projects may be collaborative so worth considering...

Where to host an Open Source Project: CodePlex, Google Code, SourceForge?

&gt; **Possible Duplicate:**  
&gt; [Open Source Alternatives to Reflector?](https://stackoverflow.com/questions/2425973/open-source-alternatives-to-reflector)  
&gt;
&gt; I don&#39;t consider this to be a duplicate, as the contact of the other questions is about learning how reflector works, and this question is about coping when reflector stops being free

Now that Red-Gate has said .NET Reflector will [no longer be free][1], is there an alternative that save the pain of getting a purchase order approved?

It seems that [jetbrains may be bringing out a tool][2]:

&gt; Good news is that we’re preparing a
&gt; standalone binary-as-a-source
&gt; application, i.e. a decompiler +
&gt; assembly browser to explore whatever
&gt; .NET compiled code is legal to
&gt; explore. We don’t have any specific
&gt; date for release, but it’s going to be
&gt; released this year, and it’s going to
&gt; be free of charge. And by saying
&gt; “free”, we actually mean “free”.

Also [ilspy][3] is a new open source tool that seems to be making good progress.
ILSpy is the open-source .NET assembly browser and decompiler.

&gt; Development started after Red Gate
&gt; announced that the free version of
&gt; .NET Reflector would cease to exist by
&gt; end of February 2011.

Is there a “free” alternative to .NET Reflector?

Does C (or any other low-level language, for that matter) even have source, or is the compiler the part that &quot;does all the work&quot;, including parsing? If so, couldn&#39;t different compilers have different C dialects? Where does the stdlib factor into this? I would really like to know how this works.

Is C open source?

I&#39;m looking for a library to generate QR codes in .NET I&#39;ve stumbled across a few paid ones, but very few free ones that look any good. Anyone have experience with a good free open-source library?

Thanks
