• Ubuntu 14.04.1 will not load - stops in tty1

  - by Mitya Stiglitz

  I was following some "guides" on how to clean my system and have cleaned it so well that it doesn't work anymore. Example: in synaptic, I completely removed all packages in "Not installed: residual configuration" and a ton of other packages I "don't need". I know this has probably been asked a trillion times but I really need to find out how to get back to the working OS I had about two hours ago. One hour of googling has not helped me, so I am asking here. When I start Ubuntu, usually nothing happens for quite some time and then tty1 starts. I can log in normally, but I don't know how to proceed from there. I can do: less /var/log/apt/history.log and get a log, but I don't know how to get started with this...

• Facebook like button for a Facebook feed item

  - by jverdeyen

  Here is what I do: When the admin of a website i'm creating adds a new 'news' item to his website, it directly posts the same item on the Facebook 'fanpage' of the website. This is done by an Facebook app with the permissions to post an item on the Facebook fanpage. So far so good. I'm getting the new post id from the facebook graph. Here is what I want to achieve: I'm adding a 'like' button on the original website, but when this is clicked it should be referenced to the same post item on the facebook page. So if someone likes the news post on the website he should also like the referencing facebook feed post. Which is exactly the same. Can this be done? I've been playing around with the href etc of the like button, without any success. When I hit the like button it likes the url given, but is doesn't recognizes that this is a feed post. Any idea? Thx in advance.

• logging a facebook user ID to a local database from a facebook 'like'

  - by Azzam

  I am creating a site that allow users to vote on webpages similar to digg.com. Users login with 'facebook connect' and logged in users can submit, vote, comment, etc and these details appear in their profile ie. number of submits, votes, comments, etc. I have also added in facebook 'likes' to the system. I would however like to be able replace the internal voting platform with facebook 'likes'. What I would like to be able to do is identify when any of the site users vote on a facebook 'like'. Although a facebook 'like' can be made outside of my site I am only interested when a logged in user submits a 'like' so this can contribute towards their stats. Is this possible, if so how? Thanks Azzam

• Example to get Facebook Events using sdk v4 from fan page into Wordpress site [on hold]

  - by Dorshin

  Been trying to update to the new FB php sdk v4 for pulling events into my website, but having trouble finding how to do it. I want to pull public event information from a FB "page" using their fan page ID number. For example, a venue that has multiple events. What are the minimal classes I need to "require_once" and "use" to only pull the events (don't need to login)? The site is on Wordpress which doesn't use sessions, so what do I do with the "session_start()" statement? Will it work anyway? Could I get a basic code example of how to get the event info into an array? (I want to make sure I get the syntax correct) So far I've got the below code, but it is not working. session_start(); require_once( 'Facebook/GraphObject.php' ); require_once( 'Facebook/GraphSessionInfo.php' ); require_once( 'Facebook/FacebookSession.php' ); require_once( 'Facebook/FacebookCurl.php' ); require_once( 'Facebook/FacebookHttpable.php' ); require_once( 'Facebook/FacebookCurlHttpClient.php' ); require_once( 'Facebook/FacebookResponse.php' ); require_once( 'Facebook/FacebookSDKException.php' ); require_once( 'Facebook/FacebookRequestException.php' ); require_once( 'Facebook/FacebookAuthorizationException.php' ); require_once( 'Facebook/FacebookRequest.php' ); require_once( 'Facebook/FacebookRedirectLoginHelper.php' ); use Facebook\GraphSessionInfo; use Facebook\FacebookSession; use Facebook\FacebookCurl; use Facebook\FacebookHttpable; use Facebook\FacebookCurlHttpClient; use Facebook\FacebookResponse; use Facebook\FacebookAuthorizationException; use Facebook\FacebookRequestException; use Facebook\FacebookRequest; use Facebook\FacebookSDKException; use Facebook\FacebookRedirectLoginHelper; use Facebook\GraphObject; function facebook_event_function() { FacebookSession::setDefaultApplication('11111111111','00000000000000000'); /* make the API call */ $request = new FacebookRequest($session, '/{123456789}/events','GET'); $response = $request->execute(); $graphObject = $response->getGraphObject(); } So far, not getting anything in the $graphObject and it's throwing this error as well: PHP Fatal error: Uncaught exception 'Facebook\FacebookAuthorizationException' with message '(#803) Some of the aliases you requested do not exist: v2.0GET' in ../Facebook/FacebookRequestException.php:134 After I get something in the $graphObject, I want to add the info to a DB table. This part I am OK on. Thank you for the help.

• how to resume facebook session key after user change facebook password

  - by aviavi

  hey i have iphone application that using facebook connect. users login to the iphone application using facebook connect. and then i receive their sessionKey back to my server, and i am using the sesssionkey to post actions to users wall. the iphone application keeps the user logged in allways. which means that every times the user will open the application, he will not need to make login again. the problem is that, when the user change his facebook password the user sessionKey also changes. and when the user enter to my iphone applicaiton, the user is shown as loggedin, and then i recieve to my server the user old sessionkey, and when i try to post to the user wall facebook tells me that the session is inavlid. it is ok because the user change his password and the session changes too. my question is how can i check in the iphone if the session key has changed ? and if it changes to promote the user to make login again.

• Facebook link to facebook.com/company-page doesn't work

  - by Teo

  For the last 2 days I'm trying to find the reason why my previous setup, which was a link to my websites Facebook pages doesn't work anymore. I assume that I mistakenly changed something in the Facebook developer area, but I can't remember what it was. The bottom linked my previously to the Facebook.com/company-page, now the same Bottom links me just to Facebook.com. I guess I saw some redirect in the tab, but I'm not sure since it's too fast changing to Facebook.com. The original link in the footer is correct : <a href="http://facebook.com/company-page " target="_blank" class="facebook_ico"></a>. Any ideas?

• Facebook events api: Event member (FQL)

  - by sunil-khedar

  I am fetching the event members for facebook events. Till yesterday I was getting the proper counts of members of an event. But suddenly the counts have following issues: For lot of plans on every consecutive request, I am getting random number of members. Strange issue. Seems facebook servers are not synced properly or something similar. Earlier for the same query string (mentioned below), I was getting the correct counts. But now the count is much less. It seems that at least for a few events now they are sending only the members who are connected with our application (we are using facebook connect). Example: for the following query currently I am getting "31" members. But on event page members count is much more. FQL: FB.Facebook.apiClient.fql_query('SELECT uid, eid, rsvp_status FROM event_member WHERE eid=336671213618', function(result, error){alert(result.length);}); Event page: http://www.facebook.com/event.php?eid=109411842404023 Is there any recent change in facebook API or policies? Thanks in advance.

• What is the difference between a Facebook Group and a Facebook Page

  - by jmort253

  I created a Project Management Stack Exchange Facebook Page to help promote the new Project Management Stack Exchange Site. One of the users suggested a Facebook Group instead. I use Facebook, and I've searched the help pages, but it's not immediately clear to me what the advantages and disadvantages are. Can you provide a list of uses for Groups and uses for Facebook Pages and perhaps some links to resources that help differentiate one from the other?

• How to remove a Facebook App from Facebook's search results?

  - by Gavin

  I have a Facebook app so users can login to my website using their Facebook account, but when you type my website name into Facebook's search (the search box right next to the Facebook logo) the app shows up in the search results. When I click it, it says "Misconfigured App - Sorry, the details for AppName cannot be displayed because the app is misconfigured." I want to remove my app from Facebook's search results, because it's not meant for users, but I can't figure out how to do it. Any ideas?

• How to send a Facebook notification through their API

  - by at

  I asked this on the Facebook Developers Forum with no responses.. How do I send notifications to users so they show up in the Notifications globe icon tab on the top left of a user's Facebook page? Some applications I use have their notifications show up there, but I don't see how that mechanism works in Facebook's API docs. Neither are there any permissions which seem to be required to send users notifications.

• Facebook like and share create a fanpage

  - by nblumoe

  We are using the facebook like plugin with the share button. The URL points to a resource of our app. For example http://apps.facebook.com/appname/resources/id The first time this resource/url is shared or liked, everything works fine. The share for example holds the URL given above. But if the same resource/url is shared again, an error occurs. Facebook did create a fanpage for that resource like http://www.facebook.com/pages/appname So from now on, share/likes refer to that page instead of the resource/url of our app. The URL we use for the like plugin is correct and always points to the app resource URL. The fbappid in there is correct, too. Furthermore the page of the resource holds open graph meta tags like og:url, also pointing to the correct URL. The facebook linter/debugger returns URLs to the correct app resource URLs, when checking the liked/shared resource. Why is a fanpage created instead and the URL exchanged in shares/likes? How to fix it? We want the share to include the URL of the app resource and to increase the like count for that open graph object.

• Cocos2d: Changing b2Body x val every frame causes jitter

  - by Joey Green

  So, I have a jumping mechanism similar to what you would see in doodle jump where character jumps and you use the accelerometer to make character change direction left or right. I have a player object with position and a box2d b2Body with position. I'm changing the player X position via the accelerometer and the Y position according to box2d. pseudocode for this is like so -----accelerometer acceleration------ player.position = new X -----world update--------- physicsWorld-step() //this will get me the new Y according to the physics similation //so we keep the bodys Y value but change x to new X according to accelerometer data playerPhysicsBody.position = new pos(player.position.x, keepYval) player.position = playerPhysicsBody.position Now this is simplifying my code, but I'm doing the position conversion back and forth via mult or divide by PTM_. Well, I'm getting a weird jitter effect after I get big jump in acceleration data. So, my questions are: 1) Is this the right approach to have the accelerometer control the x pos and box2d control the y pos and just sync everthing up every frame? 2) Is there some issue with updating a b2body x position every frame? 3) Any idea what might be creating this jitter effect? I've collecting some data while running the game. Pre-body is before I set the x value on the b2Body in my update method after I world-step(). Post of course is afterwards. As you can see there is definitively a pattern. 012-06-19 08:14:13.118 Game[1073:707] pre-body pos 5.518720~24.362963 2012-06-19 08:14:13.120 Game[1073:707] post-body pos 5.060156~24.362963 2012-06-19 08:14:13.131 Game[1073:707] player velocity x: -31.833529 2012-06-19 08:14:13.133 Game[1073:707] delta 0.016669 2012-06-19 08:14:13.135 Game[1073:707] pre-body pos 5.060156~24.689455 2012-06-19 08:14:13.137 Game[1073:707] post-body pos 5.502138~24.689455 2012-06-19 08:14:13.148 Game[1073:707] player velocity x: -31.833529 2012-06-19 08:14:13.150 Game[1073:707] delta 0.016667 2012-06-19 08:14:13.151 Game[1073:707] pre-body pos 5.502138~25.006948 2012-06-19 08:14:13.153 Game[1073:707] post-body pos 5.043575~25.006948 2012-06-19 08:14:13.165 Game[1073:707] player velocity x: -31.833529 2012-06-19 08:14:13.167 Game[1073:707] delta 0.016644 2012-06-19 08:14:13.169 Game[1073:707] pre-body pos 5.043575~25.315441 2012-06-19 08:14:13.170 Game[1073:707] post-body pos 5.485580~25.315441 2012-06-19 08:14:13.180 Game[1073:707] player velocity x: -31.833529 2012-06-19 08:14:13.182 Game[1073:707] delta 0.016895 2012-06-19 08:14:13.185 Game[1073:707] pre-body pos 5.485580~25.614935 2012-06-19 08:14:13.188 Game[1073:707] post-body pos 5.026768~25.614935 2012-06-19 08:14:13.198 Game[1073:707] player velocity x: -31.833529 2012-06-19 08:14:13.199 Game[1073:707] delta 0.016454 2012-06-19 08:14:13.207 Game[1073:707] pre-body pos 5.026768~25.905428 2012-06-19 08:14:13.211 Game[1073:707] post-body pos 5.469213~25.905428 2012-06-19 08:14:13.217 Game[1073:707] acceleration x -0.137421 2012-06-19 08:14:13.223 Game[1073:707] player velocity x: -65.022644 2012-06-19 08:14:13.229 Game[1073:707] delta 0.016603

• Ubuntu 10.04 and fedora 14 grub conflict

  - by sawren

  I tried to triple boot Windows xp, Fedora 14 and Ubuntu 10.04. I first installed Windows xp, then fedora followed by Ubuntu. The problem is that i don't get option to boot Ubuntu while Xp boots fine. It seems Ubuntu was unable to replace Fedora's grub with its own at MBR. Looking at their grub conf file, Fedora and Ubuntu identifies same harddisk as two different devices and i do have another 80 GB harddisk which doesn't have any OS. Below is the details on my partitions and partial information from grub files of both OS.

• Facebook Application Tab URL

  - by Paul

  I have a facebook application that can be added to fan pages as a tab. The application requires that users are authenticated in order to use it. This can be accomplished by using requirelogin=1 in a link which is visible only to users who have NOT added the application. This part works fine. However, after the user has given my application permission from the dhtml pop up that requirelogin opens, I want the tab to reload. In order to do that, I need the full URL to be included in the link as follows: <a href="http://www.facebook.com/pages/PAGE_NAME/PAGE_ID?v=app_APP_ID" requirelogin=1>Authorize</a> I cannot figure out how to get the full url or, at least, the PAGE_NAME to build this url dynamically. Seems like the app should be able to know where it is without any special permissions.

• Navigating between pages in a Facebook Platform iframe application

  - by Jimmy Cuadra

  I'm working on a Facebook Platform application that runs in iframe mode, and I'm having trouble understanding how to navigate between pages within the app. Let's say the first page that is loaded within the iframe at my canvas URL is one.html. Within that page, there is a link to two.html that just changes the source of the iframe and doesn't reload the Facebook chrome. When I do this, all the Facebook fb_sig_* query string parameters that Facebook passes to the original page aren't included, and so two.html has no awareness of the connection to Facebook and no ability to make API calls to generate the content for the page. One possible solution would be to manually extract all the Facebook parameters from one.html and append it to the link to two.html myself. This seems really ugly and I figured there had to be a cleaner way. For reference, my application is written in Perl and uses the WWW::Facebook::API module as a client library. I didn't see anything in it that I can use to easily reconstruct the Facebook parameters for use with links in iframe apps. Another possible solution would be to store all the Facebook parameters in a session on my server on the first page load, and just use the values in that session on subsequent page views. But what happens if the data I've stored no longer matches what Facebook would have sent if it were a completely new request (i.e. something in the user's Facebook session changed)? Is there something obvious I'm missing? What is the standard approach to navigating between pages within an iframe app? Facebook's documentation is atrocious and I haven't been able to find anything that clearly explains how this works. I also realize this wouldn't be an issue with an app using FBML instead of an iframe, but my understanding is that iframe apps are now encouraged over FBML apps, though again this seems ambiguous since so much of Facebook's documentation is outdated and contradictory.

• Linking a facebook app's page to an existing facebook business page

  - by Dan

  I have a facebook app page, and a separate facebook business profile page. The business page was created, but not by me, some time before the app and its page were created. Is there any way to connect the two pages, or import the content and friends from one to the other? The older profile page has some content; a set of friends and wall posts that I don't want to lose. It was created before I had a chance to set up an app page. Since the app was created more recently, it does not have any content posted to it. I intended the app page to eventually hold some advertising info for my main website itself (non-canvas, just using fb for the connect api etc). The idea being that as people sign up on my site through facebook's OAuth, I could use the graph api to post to their wall. The wall posts are working as expected but naturally they are directing users to the facebook app page, which has no content, friends etc. I'd prefer to be directed to the original business page, where the party is really happening. Now it seems that the two pages are completely separate; what would I need to do to direct the users to the business page?

• Auto Login facebook user into application

  - by user537562

  So, Here is the scenario I am trying to fix. A returning user is logged into facebook but not logged into the application. In this case when the user tries to load the application, since the user cookie is not attained yet, it redirects the user to the login page. I googled around and found this solution, FB.Event.subscribe('auth.sessionChange', function(response) { if (response.session) { window.location.reload(); } } basically whats happening here is, we are registering to facebook for a login/logout event and when it receives a response, we reload the page. Now its loads the right page since we have the user cookie on our site domain after the first load. this works, but the problem is the double load. It takes a lot of time. How can I attain the user cookie on server side for returning user? so that I don't have to do the initial page reload. Also, I have looked at yelp, and somehow they are able to load the user information without doing double load, does any body know they are able to do it? Any help is greatly appreciated, Thanks!

  According to http://github.com/facebook/python-sdk/blob/master/src/facebook.py , In my canvas application, i can do the following call to get my access_token, which will work because my user has used facebook to login: import facebook myDict = facebook.get_user_from_cookie(cookies, app_id, app_secret) # my access_token is myDict["access_token"] myDict is alwas None, any ideas?
