`og:title` is one of the open graph meta tags. `og:...` properties define objects in a social graph. They are used for example by Facebook.

`og:title` stands for the title of your object as it should appear within the graph (see here for more [http://ogp.me/][1] )


  [1]: http://ogp.me/

The `property` in meta tags allows you to specify values to property fields which come from a property library. The property library (RDFa format) is specified in the head tag.

For example, to use that code you would have to have something like this in your `&lt;head` tag. `&lt;head xmlns:og=&quot;http://example.org/&quot;&gt;` and inside the `http://example.org/` there would be a specification for `title` (og:title).

The tag from your example was almost definitely from the [Open Graph Protocol](http://ogp.me/), the purpose is to specify structured information about your website for the use of Facebook (and possibly other search engines).

A degree of control is possible over how information travels from a **third-party website to Facebook** when a page is shared (or liked, etc.). In order to make this possible, information is sent via Open Graph meta tags in the `&lt;head&gt;` part of the website’s code.

Probably part of [Open Graph Protocol][1] &lt;strike&gt;for Facebook&lt;/strike&gt;.

Edit: guess not only Facebook - that&#39;s only one example of using it.

It feels  strange to me to use `-Wl,-Bstatic` in order to tell `gcc` which libraries I want to link with statically. After all I&#39;m telling `gcc` directly all other information about linking with libraries (`-Ldir`, `-llibname`).

Is it possible to tell the gcc driver directly which libraries should be linked statically?

**Clarification:** I know that if a certain library exists only in static versions it&#39;ll use it  without `-Wl,-Bstatic`, but I want to imply `gcc` to prefer the static library. I also know that specifying the library file directly would link with it, but I prefer to keep the semantic for including static and dynamic libraries the same.

HTML5 supports the `&lt;svg&gt;` tag, allowing to embed SVG into HTML.

Digging a little deeper, can I nest some HTML inside my `&lt;svg&gt;` fragment? For example, I&#39;d like to put a CSS&#39;ed `&lt;table&gt;` in some part of my SVG graphics.

I made a small test and Chrome12 didn&#39;t like the HTML `&lt;p&gt;` inside the `&lt;svg&gt;`.
Is there some technique to make it work (such as maybe an html container tag?)?

Can I embed HTML into an HTML5 SVG fragment?

Can someone please help me get my head around this bug? With Firefox its working fine but with Internet Explorer 7 its not. It seems not to understand the `display: inline-block;`.


**html:**

    	&lt;h2&gt;...&lt;/h2&gt;
    &lt;/div&gt;

I have an HTML login form that contains following elements (in this order):

- `input type=text` (user name input)
- `input type=password` (password)
- `input type=submit` (Login button)

Why does the Android browser show &quot;Go&quot; button in soft keyboard instead of &quot;Next&quot; button when the focus is in the `text input`? This causes user to fail to login very easily because after entering the user name, the user presses the bottom right button in the keyboard (usually the correct action) and the form will be submitted with an empty password, which obviously is not going to work. [This behavior would make sense in case my browser was set to remember passwords and the password manager would be able to fill in the password. However, this is not the case here as you can test yourself below.]

I&#39;d like to have the input type text to have &quot;Next&quot; button and the input type password (the last input before the submit) to have the &quot;Go&quot; button.

An example of problematic form is at https://peda.net/:login (this form contains code to detect &quot;Enter&quot; key for the input and prevents submitting the form unless the last visible form input is focused).

Do you know a real fix for this issue? I know that if I were implementing native application, I&#39;d use `android:imeOptions=&quot;actionNext&quot;` (see https://stackoverflow.com/questions/6327886/how-to-change-the-softkey-keyboard-go-button-to-next-android). However, in this case it&#39;s an HTML form and Android default browser.

The problem is visible with at least following configurations:

- &quot;Browser&quot; system app running on Android 2.3.4 (Cyanogenmod 7)
- &quot;Browser&quot; system app running on Android 4.2.2 (Cyanogenmod 10.1)
- &quot;Browser&quot; system app running on Android 4.3.1 (Cyanogenmod 10.2 M1)
- &quot;Browser&quot; system app (AOSP Browser) running on Android 4.4.2 (Cyanogenmod 11.0 M3)
- &quot;Browser&quot; system app (AOSP Browser) running on Android 5.5.1 (Cyanogenmod 12.1) [has an arrow icon instead of word &quot;Go&quot;]
- &quot;Browser&quot; system app (AOSP Browser) running on Android 6.0.1 (Cyanogenmod 13.0) [has an arrow icon instead of word &quot;Go&quot;]

If I have a `.html` file in a GitHub repository, e.g. for running a a set of JavaScript tests, is there any way I can view that page directly—thus running the tests?

For example, could I somehow actually see the test results that would be produced by [the jQuery test suite][1], without downloading or cloning the repo to my local drive and running them there?

I know this would basically put GitHub in the static content hosting business, but then again, they just have to change their mime-type from [`text/plain`][2] to `text/html`.

When you share a link on facebook it will automatically find images on the website and randomly picks one as a preview. How can you influence the preview image? When a person shares the website link on his facebook?

How can I set a website image that will show as preview on Facebook?

I am modifying my app to be able to catch if a user tries to publish without having the facebook app installed (required for SSO).  Here is the code I am using:

    try{
		ApplicationInfo info = getPackageManager().
                getApplicationInfo(&quot;com.facebook.android&quot;, 0 );
	    return true;
	} catch( PackageManager.NameNotFoundException e ){
	    return false;
    }

The problem is, it is always catching an error.  According to the question [here], I need to request the appropriate permission but I don&#39;t know what permissions I need to request.

Is my problem a permission one or something else?

How to check if Facebook is installed Android

I need to develop an app that has the share function. I have to share on Facebook, twitter, email and maybe other services. 

How can I do this? There a library on the net? For the iOS development there were ShareKit, but for Android?

Thanks :)

Facebook callback has started appending `#_=_` hash underscore to the Return URL

Does anyone know why? What is the solution?

Facebook Callback appends &#39;#_=_&#39; to Return URL

Why does it always happen to me?

This happens after my application verify for user user login and redirect user to the authentication page:  

`https://www.facebook.com/dialog/oauth?client_id=XXX&amp;redirect_uri=http%3A%2F%2Fexample.com%2Fmyappname%2F&amp;state=YYYYYY&amp;scope=offline_access%2Cpublish_actions`

But instead of showing the authorization page, Facebook shows an error page with 
&gt; An error occurred. Please try again later.


Is there any configuration I have to do before try to authenticate my users?

All is done with PHP using the PHP-SDK classes.

Here is a pure Python-specific design question: 

    class MyClass(object):
        ...
        def get_my_attr(self):
            ...

        def set_my_attr(self, value):
            ...

and 

    class MyClass(object):
        ...        
        @property
        def my_attr(self):
            ...

        @my_attr.setter
        def my_attr(self, value):
            ...

Python lets us to do it either way. If you would design a Python program, which approach would you use and why?

Using @property versus getters and setters

I&#39;m currently making a .properties file that needs to be loaded and transformed into an array.  But there is a possibility of anywhere from 0-25 of each of the property keys to exist.  I tried a few implementations but i&#39;m just stuck at doing this cleanly.  Anyone have any ideas?


    foo.1.filename=foo.txt
    foo.1.expire=200
    
    foo.2.filename=foo2.txt
    foo.2.expire=10
    
    etc more foo&#39;s
    
    bar.1.filename=bar.txt
    bar.1.expire=100

where I&#39;ll assemble the filename/expire pairings into a data object, as part of an array for each parent property element like `foo[myobject]`

Formatting of the properties file can change, I&#39;m open to ideas.

Better way to represent array in java properties file

So, I&#39;m trying to figure out the best (most elegant with the least amount of code) way to allow overriding specific functions of a property (e.g., just the getter, just the setter, etc.) in python.  I&#39;m a fan of the following way of doing properties, due to the fact that all of their methods are encapsulated in the same indented block of code (it&#39;s easier to see where the functions dealing with one property stop and the functions dealing with the next begin):

    @apply
    def foo():
        &quot;&quot;&quot;A foobar&quot;&quot;&quot;
        def fget(self):
            return self._foo
        def fset(self, val):
            self._foo = val
        return property(**locals())

However, if I want to inherit from a class that defines properties in this manner, and then, say, override the `foo` setter function, it seems tricky.  I&#39;ve done some searching and most of the answers I&#39;ve found have been to define separate functions in the base class (e.g. `getFoo` and `setFoo`), explicitly create a property definition from them (e.g. `foo = property(lambda x: x.getFoo(), lambda x, y: x.setFoo(y), lambda x: x.delFoo())`), and then override `getFoo`, `setFoo`, and `delFoo` as needed.

I dislike this solution because it means I have to define lambas for every single property, and then write out each function call (when before I could have just done `property(**locals())`).  I also don&#39;t get the encapsulation that I had originally.

Ideally, what I would like to be able to do would be something like this:

    class A(object):
        def __init__(self):
            self.foo = 8
        @apply
        def foo():
            &quot;&quot;&quot;A foobar&quot;&quot;&quot;
            def fget(self):
                return self._foo
            def fset(self, val):
                self._foo = val
            return property(**locals())

    class ATimesTwo(A):
        @some_decorator
        def foo():
            def fset(self, val):
                self._foo = val * 2
            return something

And then the output would look something like:

    &gt;&gt;&gt; a = A()
    &gt;&gt;&gt; a.foo
    8
    &gt;&gt;&gt; b = ATimesTwo()
    &gt;&gt;&gt; b.foo
    16

Basically, `ATimesTwo` inherits the getter function from `A` but overrides the setter function.  Does anybody know of a way to do this (in a manner that looks similar to the example above)?  What function would the `some_decorator` look like, and what should the `foo` function return?

Overriding properties in python

Can a reserved word be used as an object&#39;s property name?

This issue was raised indirectly in a previous Stack Overflow question: https://stackoverflow.com/questions/5306315/browser-support-for-using-a-reserved-word-as-a-property-name-in-javascript. The answer seemed general consensus by [Alex Wayne](https://stackoverflow.com/users/62076/alex-wayne): 

&gt; You can use those words, but only as strings and not shorthand
&gt; properties.
&gt; 
&gt;     foo[&#39;class&#39;]; // cool
&gt;     foo.class;    // not cool

While I think that they are probably more knowledgeable than me in this area and it is probably a _bad idea_ to use reserved words in some situations, I think their conclusion is wrong based on two points:

* testing of the reserved words using them as a &quot;shorthand&quot; properties

* the HTMLFormElement makes it impossible _not_ to use reserved words in &quot;shorthand&quot;

First, using the reserved word list, each was added as a property to an `Object` and `HTMLElement`, both as `obj[&quot;word&quot;]` and `obj.word`, and then retrieved as `obj[&quot;word&quot;]` and `obj.word`.  In each of the 63 cases all eight tests worked correctly.

Second, the HTMLFormElement necessitates this works because it retrieves in its elements using shorthand notation.  If `&lt;input name=&#39;typeof&#39; value=&#39;scalar&#39; /&gt;` is an element of a form, then `form.typeof` == &quot;scalar&quot;.

From my experience, reserved words are usually data inflicted (e.g. a column named &quot;private&quot;), not program inflicted. As such they contaminate JSON objects, and from there input, and from there the HTMLFormElement. Simply put, without a huge amount of (IMHO unnecessary) work, it&#39;s impossible to keep reserved words _not_ being forced to work correctly in shorthand.

It seems to me these real problems:

* care needs to be taken not to conflict with existent **properties**, not reserved words

* (many if not all) **variables** cannot be reserved words

* use of reserved words as properties can be (but are not necessarily) confusing

Is this conclusion correct then, that reserved words as property names, and accessing them either as strings or shorthand, is just fine - as long as a little common sense is applied to the situation?

As the title implies I&#39;m trying to generate Facebook Open Graph meta tags dynamically, but I can&#39;t get it working. Is it even possible?&lt;br&gt;

&lt;h1&gt;UPDATE:&lt;/h1&gt;
&lt;p&gt;Finally I got it working with the help of @saccharine. The following code is working for me: &lt;/p&gt;

    &lt;?php
    
    $params = array();
    if(count($_GET) &gt; 0) {
    	$params = $_GET;
    } else {
    	$params = $_POST;
    }
    // defaults
    if($params[&#39;type&#39;] == &quot;&quot;) $params[&#39;type&#39;] = &quot;restaurant&quot;;
    if($params[&#39;locale&#39;] == &quot;&quot;) $params[&#39;locale&#39;] = &quot;en_US&quot;;
    if($params[&#39;title&#39;] == &quot;&quot;) $params[&#39;title&#39;] = &quot;default title&quot;;
    if($params[&#39;image&#39;] == &quot;&quot;) $params[&#39;image&#39;] = &quot;thumb&quot;;
    if($params[&#39;description&#39;] == &quot;&quot;) $params[&#39;description&#39;] = &quot;default description&quot;;

    &lt;/html&gt;

or this:&lt;br&gt;
http://mysite.com/index.php?locale=de_DE&amp;description=hi&amp;type=bistro &lt;br&gt;

Having that accomplished: I can now publish actions to the user&#39;s stream:

    function postRestaurant() {
    	FB.api(&#39;me/MY_APP_NAMESPACE:have_lunch?\
    	start_time=2000-12-12T04:00:00&amp;\
    	expires_in=7200&amp;\
    	restaurant=&#39; + encodeURIComponent(getRedirectURI() + &#39;?type=restaurant&#39; + &#39;&amp;description=arnold&#39; + &#39;&amp;title=stalone&#39;), &#39;post&#39;, function (response) {
    		if (!response || response.error) {
    			console.log(&#39;postRestaurant: Error occured =&gt; &#39; + response.error.message);
    		} else {
    			console.log(&#39;postRestaurant: Post was successful! Action ID: &#39; + response.id);
    		}
    	});
    }

Works like a charm! : ]

Generating Facebook Open Graph meta tags dynamically

I work on a large scale, high volume, public facing web application. The successful operation of the application is very important to the business, and so there are a number of MI tools that run against it.

One of these MI tools essentially looks at the html that is sent to the browser for each page request (I&#39;ve simplified it quite a lot, but for the purpose of this question, its a tool that does some analysis on the html)

For this MI tool to get the data it needs, we put meta data in the head element. Currently we do it as html comments:

    &lt;!doctype html&gt;
    &lt;html xmlns=&quot;http://www.w3.org/1999/xhtml&quot; xml:lang=&quot;en&quot; lang=&quot;en&quot; class=&quot;&quot;&gt;
    &lt;head&gt;
    	&lt;!-- details = 52:AS6[rxSdsMd4RgYXJgeabsRAVBZ:0406139009] --&gt;
    	&lt;!-- policy id = 1234567890 --&gt;
    	&lt;!-- party id = 0987654321 --&gt;
    	&lt;!-- email address = user@email.com --&gt;
    	&lt;!-- error = 49 --&gt;
    	&lt;!-- subsessionid = bffd5bc0-a03e-42e5-a531-50529dae57e3--&gt;
    	...

And the tool simply looks for a given meta data comment with a regex

As this data is meta data, I&#39;d like to change it to html meta tags because it feels semantically correct. Something like this:

    &lt;!doctype html&gt;
    &lt;html xmlns=&quot;http://www.w3.org/1999/xhtml&quot; xml:lang=&quot;en&quot; lang=&quot;en&quot; class=&quot;&quot;&gt;
    &lt;head&gt;
    	&lt;meta name=&quot;details&quot; content=&quot;52:AS6[rxSdsMd4RgYXJgeabsRAVBZ:0406139009]&quot; /&gt;
    	&lt;meta name=&quot;policyId&quot; content=&quot;1234567890&quot; /&gt;
    	&lt;meta name=&quot;partyId&quot; content=&quot;0987654321&quot; /&gt;
    	&lt;meta name=&quot;emailAddress&quot; content=&quot;user@email.com&quot; /&gt;
    	&lt;meta name=&quot;error&quot; content=&quot;49&quot; /&gt;
    	&lt;meta name=&quot;subsessionid&quot; content=&quot;bffd5bc0-a03e-42e5-a531-50529dae57e3&quot; /&gt;
    	...

This feels more semantic, and I can get the MI tool to work with it no problem - just a case of changing the regexes. However it now gives me a problem with the w3c validator. It wont validate because the meta names I&#39;m using are not recognised. I get the error &quot;Bad value details for attribute name on element meta: Keyword details is not registered.&quot; and it suggests I register these name values on the WHATWG wiki.

Whilst I could do this it doesn&#39;t feel right. Some of my meta tags are &#39;generic&#39; (such as error and emailAddress) so I could probably find an already registered name value and use that. However, most of them are industry/organisation specific. It feels wrong to register a public name value called subsessionid or partyId as these are specific to my organisation and the application.

So, the question is - what is considered best practice in this case? Should I leave them as html comments? Should I use meta tags as above and not worry that w3c validation fails? (though that is increasingly important to the organisation) Should I attempt to register my meta name values on WHATWG wiki, but knowing they are not very generic? Or is there another solution?

Appreciate your thoughts, cheers

Edited to show the the final solution:

The full answer I&#39;m going with is as follows. Its based on Rich Bradshaws answer, so his is the accepted one, but this is what I&#39;m going with for completeness:

    &lt;!doctype html&gt;
    &lt;html xmlns=&quot;http://www.w3.org/1999/xhtml&quot; xml:lang=&quot;en&quot; lang=&quot;en&quot; class=&quot;&quot;&gt;
    &lt;head&gt;
    	&lt;meta name=&quot;application-name&quot; content=&quot;Our app name&quot; 
    		data-details=&quot;52:AS6[rxSdsMd4RgYXJgeabsRAVBZ:0406139009]&quot; 
    		data-policyId=&quot;1234567890&quot;
    		data-partyId=&quot;0987654321&quot;
    		data-emailAddress=&quot;user@email.com&quot;
    		data-error=&quot;49&quot;
    		data-subsessionid=&quot;bffd5bc0-a03e-42e5-a531-50529dae57e3&quot;
    	/&gt;
        ...

This validates, so all boxes ticked :)
