• Gnome-shell fails to load on 12.10

  - by Githlar

  I'm usually the one answering questions, but in this I'm throughly stumped! My Setup: Ubuntu 12.10 (Dist upgrade form 12.04) ATI M96 [Mobility Radeon HD 4650] Upon the first installation of 12.10 I had all kinds of issues getting the Legacy ATI drivers to install (I guess the source for the drivers isn't kosher with kernel 3.5). So, I added the repository ppa:makson96/fglrx - which has a version of the ATI source patched to work with kernel 3.5. After installation of fglrx-legacy from that PPA, gnome-shell and all my graphics work fine... until today. The Problem I unsuspended my computer today and the screen was black (not off, the black from the gnome lock screen). I'd move my mouse/hit a key and the background would flash and then it'd go back to black. Restarted via VT1 Logged into Gnome (gnome-shell) session, but no gnome-shell! Investigation: First, I went to VT1 and tried export DISPLAY=:0;gnome-shell --replace. It appeared to work fine, switch back to X and nothing. Went back to VT1 and saw this error message: JS ERROR: !!! Exception was: TypeError: Object 0x7fc748129c30 is not a subclass of (null), it's a xO JS ERROR: !!! message = '"Object 0x7fc748129c30 is not a subclass of (null), it's a xO"' JS ERROR: !!! fileName = '"/usr/share/gnome-shell/js/ui/tweener.js"' JS ERROR: !!! lineNumber = '218' JS ERROR: !!! stack = '"()@/usr/share/gnome-shell/js/ui/tweener.js:218 wrapper()@/usr/share/gjs-1.0/lang.js:204 ()@/usr/share/gjs-1.0/lang.js:145 ()@/usr/share/gjs-1.0/lang.js:239 init()@/usr/share/gnome-shell/js/ui/tweener.js:49 init()@/usr/share/gnome-shell/js/ui/environment.js:96 @<main>:1 "' Window manager warning: Log level 32: Execution of main.js threw exception: TypeError: Object 0x7fc748129c30 is not a subclass of (null), it's a xO Note: Everywhere it says "it's a xO", xO is actually garbled and changes every time (I'm thinking memory corruption?) This error is thrown by line 96 of /usr/share/gnome-shell/js/ui/environment.js: tweener.Init() Did a purge of fglrx-legacy, reboot, reinstall fglrx-legacy, reboot... same thing. Did a ppa-purge of ppa:gnome3-team/gnome3, and reinstalled gnome-shell and ubuntu-desktop from the standard repositores... same thing. I'm really at a loss here.

• Rails 3: How do I call a javascript function from a js.erb file

  - by user321775

  Now that I've upgraded to Rails 3, I'm trying to figure out the proper way to separate and reuse pieces of javascript. Here's the scenario I'm dealing with: I have a page with two areas: one with elements that should be draggable, the other with droppables. When the page loads I use jQuery to setup the draggables and droppables. Currently I have the script in the head portion of application.html.erb, which I'm sure is not the right solution but at least works. When I press a button on the page, an ajax call is made to my controller that replaces the draggables with a new set of elements that should also be draggable. I have a js.erb file that renders a partial in the correct location. After rendering I need to make the new elements draggable, so I'd like to reuse the code that currently lives in application.html.erb, but I haven't found the right way to do it. I can only make the new elements draggable by pasting the code directly into my js.erb file (yuck). What I'd like to have: - a javascript file that contains the functions prepdraggables() and prepdroppables() - a way to call either function from application.html.erb or from a js.erb file I've tried using :content_for to store and reuse the code, but can't seem to get it working correctly. What I currently have in the head section of application.html.erb <% content_for :drag_drop_prep do %> <script type="text/javascript" charset="utf-8"> $(document).ready(function () { // declare all DOM elements with class draggable to be draggable $( ".draggable" ).draggable( { revert : 'invalid' }); // declare all DOM elements with class legal to be droppable $(".legal").droppable({ hoverClass : 'legal_hover', drop : function(event, ui) { var c = new Object(); c['die'] = ui.draggable.attr("id"); c['cell'] = $(this).attr("id"); c['authenticity_token'] = encodeURIComponent(window._token); $.ajax({ type: "POST", url: "/placeDie", data: c, timeout: 5000 }); }}); }); </script> <% end %> undo.js.erb $("#board").html("<%= escape_javascript(render :partial => 'shared/board', :locals => { :playable => true, :restartable => !session[:challenge]}) %>") // This is where I want to prepare draggables. <%= javascript_include_tag "customdragdrop.js" %> // assuming this file had the draggables code from above in a prepdraggables() function prepdraggables();

• Debug JS from browser without a server/localhost

  - by sazpaz

  So something I do very frequently is writing random scripts in JS without really being part of an app. To run them I just paste them in the console of either Chrome of FF which works as a nice REPL, or if I really need more fancy debugging I just add it to my test app on localhost and browse it from the browser. Is there a way to get all the good debugging of a browser (breakpoints, locals, etc), without it being served from a server?, e.g by just copy-pasting my code into console or something?

• change .htaccess to not pass .js/.css/.jpg requests through to index.php

  - by Dean

  Hey guys, bit of a mod_rewrite noob, I've got: RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 Which I believe says "If the file or directory exists, don't pass it to index.php". I'd like another line which says "If it's a .jpg, .css, .js - don't pass it to index.php". Any help appreciated. Thanks :)

• Rails 2 and Ngnix: https pages can't load css or js (but will load graphics)

  - by Max Williams

  ADMISSION: i've posted this same question on stackoverflow, before realising it's probabaly better suited to superuser, but it kind of depends on the answer: If it turns out to be a problem in my nginx config, it's definitely superuser. If it turns out to be a problem in my Rails config (or code) then it's arguably stackoverflow. I'm adding some https pages to my rails site. In order to test it locally, i'm running my site under one mongrel_rails instance (on 3000) and nginx. I've managed to get my nginx config to the point where i can actually go to the https pages, and they load. Except, the javascript and css files all fail to load: looking in the Network tab in chrome web tools, i can see that it is trying to load them via an https url. Eg, one of the non-working file urls is https://cmw-local.co.uk/stylesheets/cmw-logged-out.css?1383759216 I have these set up (or at least think i do) in my nginx config to redirect to the http versions of the static files. This seems to be working for graphics, but not for css and js files. If i click on this in the Network tab, it takes me to the above url, which redirects to the http version. So, the redirect seems to be working in some sense, but not when they're loaded by an https page. Like i say, i thought i had this covered in the second try_files directive in my config below, but maybe not. Can anyone see what i'm doing wrong? thanks, Max Here's my nginx config - sorry it's a bit lengthy! I think the error is likely to be in the first (ssl) server block: server { listen 443 ssl; keepalive_timeout 70; ssl_certificate /home/max/work/charanga/elearn_container/elearn/config/nginx/certs/max-local-server.crt; ssl_certificate_key /home/max/work/charanga/elearn_container/elearn/config/nginx/certs/max-local-server.key; ssl_session_cache shared:SSL:10m; ssl_session_timeout 10m; ssl_protocols SSLv3 TLSv1; ssl_ciphers RC4:HIGH:!aNULL:!MD5; ssl_prefer_server_ciphers on; server_name elearning.dev cmw-dev.co.uk cmw-dev.com cmw-nginx.co.uk cmw-local.co.uk; root /home/max/work/charanga/elearn_container/elearn; # ensure that we serve css, js, other statics when requested # as SSL, but if the files don't exist (i.e. any non /basket controller) # then redirect to the non-https version location / { try_files $uri @non-ssl-redirect; } # securely serve everything under /basket (/basket/checkout etc) # we need general too, because of the email/username checking location ~ ^/(basket|general|cmw/account/check_username_availability) { # make sure cached copies are revalidated once they're stale add_header Cache-Control "public, must-revalidate, proxy-revalidate"; # this serves Rails static files that exist without running # other rewrite tests try_files $uri @rails-ssl; expires 1h; } location @non-ssl-redirect { return 301 http://$host$request_uri; } location @rails-ssl { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_read_timeout 180; proxy_next_upstream off; proxy_pass http://127.0.0.1:3000; expires 0d; } } #upstream elrs { # server 127.0.0.1:3000; #} server { listen 80; server_name elearning.dev cmw-dev.co.uk cmw-dev.com cmw-nginx.co.uk cmw-local.co.uk; root /home/max/work/charanga/elearn_container/elearn; access_log /home/max/work/charanga/elearn_container/elearn/log/access.log; error_log /home/max/work/charanga/elearn_container/elearn/log/error.log debug; client_max_body_size 50M; index index.html index.htm; # gzip html, css & javascript, but don't gzip javascript for pre-SP2 MSIE6 (i.e. those *without* SV1 in their user-agent string) gzip on; gzip_http_version 1.1; gzip_vary on; gzip_comp_level 6; gzip_proxied any; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; #text/html # make sure gzip does not lose large gzipped js or css files # see http://blog.leetsoft.com/2007/7/25/nginx-gzip-ssl gzip_buffers 16 8k; # Disable gzip for certain browsers. #gzip_disable "MSIE [1-6].(?!.*SV1)"; gzip_disable "MSIE [1-6]"; # blank gif like it's 1995 location = /images/blank.gif { empty_gif; } # don't serve files beginning with dots location ~ /\. { access_log off; log_not_found off; deny all; } # we don't care if these are missing location = /robots.txt { log_not_found off; } location = /favicon.ico { log_not_found off; } location ~ affiliate.xml { log_not_found off; } location ~ copyright.xml { log_not_found off; } # convert urls with multiple slashes to a single / if ($request ~ /+ ) { rewrite ^(/)+(.*) /$2 break; } # X-Accel-Redirect # Don't tie up mongrels with serving the lesson zips or exes, let Nginx do it instead location /zips { internal; root /var/www/apps/e_learning_resource/shared/assets; } location /tmp { internal; root /; } location /mnt{ root /; } # resource library thumbnails should be served as usual location ~ ^/resource_library/.*/*thumbnail.jpg$ { if (!-f $request_filename) { rewrite ^(.*)$ /images/no-thumb.png break; } expires 1m; } # don't make Rails generate the dynamic routes to the dcr and swf, we'll do it here location ~ "lesson viewer.dcr" { rewrite ^(.*)$ "/assets/players/lesson viewer.dcr" break; } # we need this rule so we don't serve the older lessonviewer when the rule below is matched location = /assets/players/virgin_lesson_viewer/_cha5513/lessonViewer.swf { rewrite ^(.*)$ /assets/players/virgin_lesson_viewer/_cha5513/lessonViewer.swf break; } location ~ v6lessonViewer.swf { rewrite ^(.*)$ /assets/players/v6lessonViewer.swf break; } location ~ lessonViewer.swf { rewrite ^(.*)$ /assets/players/lessonViewer.swf break; } location ~ lgn111.dat { empty_gif; } # try to get autocomplete school names from memcache first, then # fallback to rails when we can't location /schools/autocomplete { set $memcached_key $uri?q=$arg_q; memcached_pass 127.0.0.1:11211; default_type text/html; error_page 404 =200 @rails; # 404 not really!

• Can't call animated png script from external js file

  - by Tomas

  Hello, I'm trying to put an animated PNG dinamicaly from external .js file. First I found a simple animated png solution, which draws an animation wherever you put the code within tags, but now it looks like I don't know how to call the function properly from external file. The script is from www.squaregoldfish.co.uk/software/animatedpng, and it looks something like this: <script type="text/javascript" src="animatedpng.js"></script> <div id="pnganim" align="center"> <script> fishAnim = new AnimatedPNG('fish', 't01.png', 3, 100); fishAnim.draw(false); </script> </div> Now, I'm trying to call this from external.js file and jquery: function addFish(){ $('#pnganim').html('<script type="text/javascript" src="animatedpng.js" />'); fishAnim = new AnimatedPNG('fish', 'fish01.png', 3, 100); myFish = fishAnim.draw(false); $('#pnganim').append(myFish); } ... and it's not working. After I click a button that calls the addFish function, it opens only the first frame on a blank page. What am I doing wrong here? Thanks

• Dynamically load Jquery into .js page

  - by RussP

  Please excuse me if I'm simple here, I want to create a simple widget that people can access from their websites - e.g by copy/past something like <script language="javascript" src="test2.js"></script> <div id="test"></div> anywhere in their web pages. where is dynamically filled via Jquery and the functions in/on test2.js. I can do it if JQuery is actually "printed" on the page of test2.js, but I cannot get any JQuery functions to work if I try to include/call JQuery dynamically. How do you call JQuery via javascript and then get it to work with the functions on the page? And/Or is there an easy way to add the <div id="test"></div> dynamically aswell? Sure I can body.append etc. but that only adds at the bottom of the page. Is there a way to .append in the position where the script include <script language="javascript" src="test2.js"></script> is actually placed? Hope I make sence.

• Sorcery/Capybara: Cannon log in with :js => true

  - by PlankTon

  I've been using capybara for a while, but I'm new to sorcery. I have a very odd problem whereby if I run the specs without Capybara's :js = true functionality I can log in fine, but if I try to specify :js = true on a spec, username/password cannot be found. Here's the authentication macro: module AuthenticationMacros def sign_in user = FactoryGirl.create(:user) user.activate! visit new_sessions_path fill_in 'Email Address', :with => user.email fill_in 'Password', :with => 'foobar' click_button 'Sign In' user end end Which is called in specs like this: feature "project setup" do include AuthenticationMacros background do sign_in end scenario "creating a project" do "my spec here" end The above code works fine. However, IF I change the scenario spec from (in this case) scenario "adding questions to a project" do to scenario "adding questions to a project", :js => true do login fails with an 'incorrect username/password' combination. Literally the only change is that :js = true. I'm using the default capybara javascript driver. (Loads up Firefox) Any ideas what could be going on here? I'm completely stumped. I'm using Capybara 2.0.1, Sorcery 0.7.13. There is no javascript on the sign in page and save_and_open_page before clicking 'sign in' confirms that the correct details are entered into the username/password fields. Any suggestions really appreciated - I'm at a loss.

• Issues with Ext-JS 1.1 date fields and Firefox 3.x / IE 8

  - by Cruachan

  I'm modifying an older website for a client that uses Ext-JS 1.1 and I'm having issues with display of date fields in IE and particularly Firefox. The site was left in a semi-implemented state previously, so there's not been a perceived problem before. In Chrome and Safari everything looks fine and the datepicker drops down and displays correctly. However in Firefox the picker is displayed widened to cover the maximum scrollable brower width (very wide indeed), and in IE it's truncated to about two thirds of the width it should be. I am somewhat uncertain that this is due to our css, but because Chrome and Safari work fine I think it might be a problem with Ext-js itself. I realise that this is an old version of Ext-JS, but because everything else works fine I don't want to go to the trouble of upgrading unless that would be very straightforward (but how difficult would that be?) I don't myself use ExtJS and this is the only website my client has with it - so I'm really looking for the simplest possible solution.

• jQuery in Opera User JS Doesn't Work

  - by Axonn

  Hello ::- ). I'm playing with some Opera User JS. I included "1jquery.min.js" in my User JS folder (1 in front because Opera loads them alphabetically). Unfortunately, it doesn't appear to be working. window.onload = OnWindowLoad; $(document).ready(function() { alert ($('#area_19')); }); function OnWindowLoad () { alert ($('#area_19')); alert(document.getElementById("area_19")); } What's interesting about this code is that the first two alerts come back in NULL, but the last one does find the object! So the element definitely exists in the page, but my jQuery seems unable to get it. What's even stranger is that the jQuery "ready" function works, indicating that I do have jQuery capability. I'm quite puzzled about all this ::- /. Hopefully somebody can give me a clue ::- ).

• Comparing YUI and Ext JS

  - by Spike Williams

  I've been using Ext JS as my rich-widget toolkit for a while, but I'm thinking of moving to YUI, partly because of the less restrictive license. The component-oriented model used in YUI seems quite similar to the one that I've enjoyed so much in Ext JS, but I'm interested in how deep those similarities are. So I'm interested in feedback from people who've used both Ext JS and YUI. What is the same, and what is different? What do I lose by moving to YUI, and what do I gain?

• Switching/Linking to another external stylesheet in a .js file using Ruby on Rails

  - by Jake

  Im learning JQuery from a Sitepoint Book but Im trying to apply all the lessons to a Rails App. In one lesson, we are taught how to switch to a different stylesheet if the browser window is resized beyond a certain point. Here's the javascript code: if ($('body').width() > 900) { $('<link rel="stylesheet" href="wide.css" type="text/css" />') .appendTo('head'); } else { $('link[href=wide.css]').remove(); } Rails doesn't seem to want to link to the new stylesheet using 'link rel'. I've tried using the Rails helper: <%= stylesheet_link_tag 'base', :media => 'screen' %> but that doesn't work in a .js file. How do I link to an external stylesheet in a .js file using Ruby? Can I use Ruby on Rails code in a .js file? Thanks.

• [JavaScript] How to get the uri of the .js file itself.

  - by Vikrant Chaudhary

  Hi, is there a method in JavaScript by which I can find out the path/uri of the executing script. For example: index.html includes a JavaScript file stuff.js and since stuff.js file depends on ./commons.js, it wants to include it too in the page. Problem is that stuff.js only knows the relative path of ./commons.js from itself and has no clue of full url/path. index.html includes stuff.js file as <script src="http://example.net/js/stuff.js?key=value" /> and stuff.js file wants to read the value of key. How to?

I have this in my .htaccess file: SetOutputFilter DEFLATE AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/x-javascript But YSlow is saying There are 4 plain text components that should be sent compressed * http://crewinyourcode.com/css/reset.css * http://crewinyourcode.com/css/inner-pages/index.css * http://crewinyourcode.com/script/css/jquery-ui-1.8.custom.css * http://crewinyourcode.com/js/inner-pages/index.js How can I gzip the css and js files? Also...I don't have access to the httpd.conf file.

• MySQL Can Connect Remotely but not Locally

  - by A Wizard Did It

  This is a weird problem and I'm not sure what's going on. I installed MySQL on a linux box I have running Ubuntu 10.04 LTS. I can access mysql via SSH mysql -p and perform all my commands that way. I added a user, and I can use AddedUser to connect remotely from my machine, but not from the local machine. It makes no sense to me... SELECT host, user FROM mysql.user Yields: +-----------+------------------+ | host | user | +-----------+------------------+ | % | AddedUser | | 127.0.0.1 | root | | li241-255 | root | | localhost | debian-sys-maint | | localhost | root | +-----------+------------------+ Problem is I'm developing on this machine using Node.js, and I can't connect locally from the server using the same username. I've tried FLUSH PRIVILEGES but that seems to have no effect. I know it's not Node.js because I'm using the same code on another database and it's working in that environment. Edit This is the error node is giving me. node.js:50 throw e; // process.nextTick error, or 'error' event on first tick ^ Error: ECONNREFUSED, Connection refused at Stream._onConnect (net.js:687:18) at IOWatcher.onWritable [as callback] (net.js:284:12) Edit 2 I have the right port & server as best I can tell. My /etc/mysql/my.cnf contains this: port = 3306 socket = /var/run/mysqld/mysqld.sock My MySQL object contains: { host: 'localhost', port: 3306, user: 'removed', password: 'removed', database: '', typeCast: true, flags: 260047, maxPacketSize: 16777216, charsetNumber: 192, debug: false, ending: false, connected: false, _greeting: null, _queue: [], _connection: null, _parser: null, server: 'ExternalIpAddress' } Possibly useful? netstat -ln | grep mysql unix 2 [ ACC ] STREAM LISTENING 1016418 /var/run/mysqld/mysqld.sock

• get js file query param from inside it

  - by vsync

  I load this file with some query param like this: src='somefile.js?userId=123' I wrote the below function in 'somefile.js' file that reads the 'userId' query param but I feel this is not the best approach. Frankly, its quite ugly. Is there a better way? function getId(){ var scripts = document.getElementsByTagName('script'), script; for(var i in scripts){ if( scripts.hasOwnProperty(i) && scripts[i].src.indexOf('somefile.js') != -1 ) var script = scripts[i]; } var s = (script.getAttribute.length !== undefined) ? script.getAttribute('src') : script.getAttribute('src', 2); return getQueryParams('userId',s); };

It simply adds # to url. In the rendered html of anchor tag, anuglar is adding ng-binding that may be the problem. Please help.

• start javascript code with $(function, etc

  - by YAmikep

  I am studying Backbone and the todo example apps from http://todomvc.com/ I have noticed there are 3 severals ways of starting the code in the files: $(function() { // code here }); $(function( $ ) { // code here }); (function() { // code here }()); I do not understand the differences and when I should use one over the other. I also saw some people using this to start their code: $(document).ready(function(){ // code here }); From what I have seen, this is the full way of writing it right? In a more general way, should I always include my javascript code into something like that in each files? Thanks for your advice.
