  • How do I control the background color during the iPhone flip view animation transition?

    - by Rob S.
    I have some pretty standing flipping action going on: [UIView beginAnimations:@"swapScreens" context:nil]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; [UIView setAnimationDuration:1.0]; [self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1]; [UIView commitAnimations]; To Apple's credit, this style of animation is amazingly easy to work with. Very cool, and I've been able to animate transitions, flips, fades etc. throughout the app very easily. Question: During the flip transition, the background visible 'behind' the two views during the flip is white and I'd like it to be black. I've: Set the background of the containing view (self.view above) - no dice. I really thought that would work. Set the background of each view to black - no dice. I didn't think this would work although you give different things a shot to understand better :) Google'd like crazy; keep landing on Safari-related listings. Thanks in advance!

  • Can't log in with a valid password using Authlogic and Ruby on Rails?

    - by kbighorse
    We support a bit of an unusual scheme. We don't require a password on User creation, and use password_resets to add a password to the user later, on demand. The problem is, once a password is created, the console indicates the password is valid: user.valid_password? 'test' = true but in my UserSessions controller, @user_session.save returns false using the same password. What am I not seeing? Kimball UPDATE: Providing more details, here is the output when saving the new password: Processing PasswordResetsController#update (for 127.0.0.1 at 2011-01-31 14:01:12) [PUT] Parameters: {"commit"="Update password", "action"="update", "_method"="put", "authenticity_token"="PQD4+eIREKBfHR3/fleWuQSEtZd7RIvl7khSYo5eXe0=", "id"="v3iWW5eD9P9frbEQDvxp", "controller"="password_resets", "user"={"password"="johnwayne"}} The applicable SQL is: UPDATE users SET updated_at = '2011-01-31 22:01:12', crypted_password = 'blah', perishable_token = 'blah', password_salt = 'blah', persistence_token = 'blah' WHERE id = 580 I don't see an error per se, @user_session.save just returns false, as if the password didn't match. I skip validating passwords in the User model: class User < ActiveRecord::Base acts_as_authentic do |c| c.validate_password_field = false end Here's the simplified controller code: def create logger.info("SAVED SESSION? #{@user_session.save}") end which outputs: Processing UserSessionsController#create (for 127.0.0.1 at 2011-01-31 14:16:59) [POST] Parameters: {"commit"="Login", "user_session"={"remember_me"="0", "password"="johnwayne", "email"="[email protected]"}, "action"="create", "authenticity_token"="PQD4+eIREKBfHR3/fleWuQSEtZd7RIvl7khSYo5eXe0=", "controller"="user_sessions"} User Columns (2.2ms) SHOW FIELDS FROM users User Load (3.7ms) SELECT * FROM users WHERE (users.email = '[email protected]') ORDER BY email ASC LIMIT 1 SAVED SESSION? false CACHE (0.0ms) SELECT * FROM users WHERE (users.email = '[email protected]') ORDER BY email ASC LIMIT 1 Redirected to http://localhost:3000/login Lastly, the console indicates that the new password is valid: $ u.valid_password? 'johnwayne' = true Would love to do it all in the console, is there a way to load UserSession controller and call methods directly? Kimball

  • looping through JSON array

    - by Phil Jackson
    Hi all. I have recently posted another question which straight away users pointed me in the right direction. $.ajax({ type: 'POST', url: './', data: 'token=' + token + '&re=8', cache: false, timeout: 5000, success: function(html){ auth(html); var JSON_array = eval(html); alert(JSON_array[0].username); } }); this returns the data correctly but I want to perform a kind of 'foreach'. the array contains data about multiple incoming and outgoing Instant Messages. So if a user is talking to more than one person at a time i need to loop through. the array's structure is as follows. Array ( [0] => Array ( [username] => Emmalene [contents] => <ul><li class="name">ACTwebDesigns</li><li class="speech">helllllllo</li></ul> <ul><li class="name">ACTwebDesigns</li><li class="speech">sds</li></ul> <ul><li class="name">ACTwebDesigns</li><li class="speech">Sponge</li><li class="speech">dick</li></ul> <ul><li class="name">ACTwebDesigns</li><li class="speech">arghh</li></ul> ) ) any help very much appreciated.

  • floating point equality in Python and in general

    - by eric.frederich
    I have a piece of code that behaves differently depending on whether I go through a dictionary to get conversion factors or whether I use them directly. The following piece of code will print 1.0 == 1.0 -> False But if you replace factors[units_from] with 10.0 and factors[units_to ] with 1.0 / 2.54 it will print 1.0 == 1.0 -> True #!/usr/bin/env python base = 'cm' factors = { 'cm' : 1.0, 'mm' : 10.0, 'm' : 0.01, 'km' : 1.0e-5, 'in' : 1.0 / 2.54, 'ft' : 1.0 / 2.54 / 12.0, 'yd' : 1.0 / 2.54 / 12.0 / 3.0, 'mile' : 1.0 / 2.54 / 12.0 / 5280, 'lightyear' : 1.0 / 2.54 / 12.0 / 5280 / 5.87849981e12, } # convert 25.4 mm to inches val = 25.4 units_from = 'mm' units_to = 'in' base_value = val / factors[units_from] ret = base_value * factors[units_to ] print ret, '==', 1.0, '->', ret == 1.0 Let me first say that I am pretty sure what is going on here. I have seen it before in C, just never in Python but since Python in implemented in C we're seeing it. I know that floating point numbers will change values going from a CPU register to cache and back. I know that comparing what should be two equal variables will return false if one of them was paged out while the other stayed resident in a register. Questions What is the best way to avoid problems like this?... In Python or in general. Am I doing something completely wrong? Side Note This is obviously part of a stripped down example but what I'm trying to do is come with with classes of length, volume, etc that can compare against other objects of the same class but with different units. Rhetorical Questions If this is a potentially dangerous problem since it makes programs behave in an undetermanistic matter, should compilers warn or error when they detect that you're checking equality of floats Should compilers support an option to replace all float equality checks with a 'close enough' function? Do compilers already do this and I just can't find the information.

    I have sort of a small parent/teacher social network set up for my school. I use my .htaccess file to make the links to teacher profiles cleaner and to add a trailing slash to all urls.

  • jQuery AJAX with two domains

    - by Andrew Burns
    OK here is the situation: I have an externally hosted CMS which works great for 99% of our needs. However on the more advanced things I inject my own CSS+JS and do magic. The problem I am running into is loading a simple HTML page from jQuery.ajax() calls. It appears to work in the sense that no warnings or errors are thrown; however in my success handler (which IS ran), the response is blank! I have been scratching my head for the whole morning trying to figure this out and the only thing I can think of is that is has something to do with the cross domain issue (even though it appears to work). Injected JavaScript: $(document).ready(function() { doui(); }); function doui() { $.ajax({ url: 'http://apps.natronacounty-wy.gov/css/feecalc/ui.htm', cache: false, success: ajax_createUI, charset: "utf-8", error: function(e) { alert(e); } }); } function ajax_createUI(data, textStatus) { alert(data); $("#ajax-content").html(data); } My ajax_createUI() success handler is called and textStatus is "success"; however data is empty. This JS file resides @ http://apps.natronacounty-wy.gov/css/js/feecalc.js however the CMS website (which gets the JS injected into it) resides @ http://www.natronacounty-wy.gov/ Am I just being stupid or is it a bug that it looks like it should be working but isn't?

  • merging two small pieces of jquery codes

    - by Billa
    Following are two pieces of jquery code. First one prints a text message when clicked on a link, and the second slides down a div when click on a link. I want to merge second code into first one, so that when I click the link, it displays the message (as the first code does), and also slides down the #votebox (as done in second code, and show content in that. I will be very thankful for any help. $("a.vote_up").click(function(){ the_id = $(this).attr('id'); $("span#votes_count"+the_id).fadeOut("fast"); $.ajax({ type: "POST", data: "action=vote_up&id="+$(this).attr("id"), url: "votes.php", success: function(msg) { $("span#votes_up"+the_id).fadeOut(); $("span#votes_up"+the_id).html(msg); $("span#votes_up"+the_id).fadeIn(); //Here, I want to slide down the votebox and content div (from code below). } }); }); The following code slides down votebox div and displays content in it, I want to include that in the above code. $("a.vote_up").click(function(){ var id=$(this).attr("id"); var name=$(this).attr("name"); var dataString = 'id='+ id + '&name='+ name; //I want to include this votebox in above code. $("#votebox").slideDown("slow"); $("#flash").fadeIn("slow"); $.ajax({ type: "POST", url: "rating.php", data: dataString, cache: false, success: function(html){ $("#flash").fadeOut("slow"); //and want to use this div as well. $("#content").html(html); } }); }); Thanks for any help.

  • How to view shell commands used by eclipse "run configurations"

    - by gmale
    Given a "run configuration" in Eclipse, I want to print out the associated shell command that would be used to run it. For example: Right now, in Eclipse, if I click "play" it will run: mvn assembly:directory -Dmaven.test.skip=true I don't see that command, I just know that's what the IDE must run, at some point. However, some of the other run configurations are far more complex with long classpaths and virtual machine options and, frankly, sometimes I have no idea what the equivalent shell command would be (particularly when it comes to Flex). There must be some way to access the shell command that would be associated with a "Run Configuration" in Eclipse/Flex Builder. This information must be available, which leads me to believe someone has written a plugin to display it. Or maybe there's already an option built into Eclipse for accessing this. So is there a way to, essentially, convert an Eclipse run configuration into a shell command? (for context only: I'm asking because I'm writing a bash script that automates everything I do, during development--from populating the Database all the way to opening Firefox and clearing the cache before running the web app. So every command I run from the IDE needs to exist in the script. Some are tricky to figure out.)

  • Getting wierd issue with TO_NUMBER function in Oracle

    - by Fazal
    I have been getting an intermittent issue when executing to_number function in the where clause on a varchar2 column if number of records exceed a certain number n. I used n as there is no exact number of records on which it happens. On one DB it happens after n was 1 million on another when it was 0.1. million. E.g. I have a table with 10 million records say Table Country which has field1 varchar2 containing numberic data and Id If I do a query as an example select * from country where to_number(field1) = 23 and id 1 and id < 100000 This works But if i do the query select * from country where to_number(field1) = 23 and id 1 and id < 100001 It fails saying invalid number Next I try the query select * from country where to_number(field1) = 23 and id 2 and id < 100001 It works again As I only got invalid number it was confusing, but in the log file it said Memory Notification: Library Cache Object loaded into SGA Heap size 3823K exceeds notification threshold (2048K) KGL object name :with sqlplan as ( select c006 object_owner, c007 object_type,c008 object_name from htmldb_collections where COLLECTION_NAME='HTMLDB_QUERY_PLAN' and c007 in ('TABLE','INDEX','MATERIALIZED VIEW','INDEX (UNIQUE)')), ws_schemas as( select schema from wwv_flow_company_schemas where security_group_id = :flow_security_group_id), t as( select s.object_owner table_owner,s.object_name table_name, d.OBJECT_ID from sqlplan s,sys.dba_objects d It seems its related to SGA size, but google did not give me much help on this. Does anyone have any idea about this issue with TO_NUMBER or oracle functions for large data?

  • Ext JS 4.2.1 loading controller - best practice

    - by Hown_
    I am currently developing a Ext JS application with many views/controlers/... I am wondering myself what the best practice is for loading the JS controllers/views/and so on... currently i have my application defined like this: // enable javascript cache for debugging, otherwise Chrome breakpoints are lost Ext.Loader.setConfig({ disableCaching: false }); Ext.require('Ext.util.History'); Ext.require('app.Sitemap'); Ext.require('app.Error'); Ext.define('app.Application', { name: 'app', extend: 'Ext.app.Application', views: [ // TODO: add views here 'app.view.Viewport', 'app.view.BaseMain', 'app.view.Main', 'app.view.ApplicationHeader', //administration 'app.view.administration.User' ... ], controllers: [ 'app.controller.Viewport', 'app.controller.Main', 'app.controller.ApplicationHeader', //administration 'app.controller.administration.User', ... ], stores: [ // stores in there.. ] }); somehow this forces the client to load all my views and controllers at startup and is calling all init methods of all controllers of course.. i need to load data everytime i chnage my view.. and now i cant load it in my controllers init function. I would have to do something like this i assume: init: function () { this.control({ '#administration_User': { afterrender: this.onAfterRender } }); }, Is there a better way to do this? Or just an other event? Though the main thing i am questioning myself is if it is the best practice to load all the javascript at startup. Wouldnt it be better to only load the controllers/views/... which the client does need right now? Or should i load all the JS at startup? If i do want to load the controllers dynamicly how could i do this? I assume a would have to remove them from my application arrays (views, controllers, stores) and create an instance if i do need it and mby set the view in the controllers init?! What's best practice??

  • Checking if radio buttons are checked in Firefox

    - by Andrew Song
    On my site, I have two checkboxes created in my ASP.NET MVC view like so: Html.RadioButton("check", "true", "true" == (string) ViewData["someKey"], new { id = "check1"}); Html.RadioButton("check", "false", "false" == (string) ViewData["someKey"], new { id = "check2"}); I am positive that ViewData["someKey"] has the value "true" in it. In my JS init function, I perform the following check: alert($('#check1').is(':checked') + " " + $('#check2').is(':checked')); In Firefox (and only Firefox), my alert dialog will show the following (it works as expected in every other browser): Initial page load: true false Normal refresh via Ctrl + R: false false Refresh skipping cache via Ctrl + Shift + R: true false I have tried many different methods of looking at the checkbox value, including $('#check1').attr('checked') without success. If I examine the HTML in Firebug, I can see that the first radio button has the property checked="checked" in it. Why is the checkbox value changing in FF when I refresh, and how can I mitigate this? Since this seems to be a FF-only bug, how can I change my code to make it work? This SO question seemed to ask something similar, but none of the proposed solutions seem to work in this case. Edit: I should also point out that when the radio button is rendered after the refresh in FF, it's not actually being displayed as checked either, despite what the HTML is telling me. Edit2: Adding raw HTML as per request <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/>

  • caching images that are retrieved

    - by Rahul Varma
    Hi, I am retrieving a list of images and text from a web service. The images are getting displayed in the list view. But the problem is, when i scroll down the list the entire images are getting loaded once again. When i scroll twice or thrice there is a OutofMemory occuring... Can anyone tell me how to cache the images and also to avoid the loading of the images that are already loaded when i scroll down. I have tried to increase inSampleSize but it didnt work... Here's the code.... public static Bitmap loadImageFromUrl(String url) { InputStream inputStream; Bitmap b; try { inputStream = (InputStream) new URL(url).getContent(); BitmapFactory.Options bpo= new BitmapFactory.Options(); b=BitmapFactory.decodeStream(inputStream, null,bpo ); b.recycle(); bpo.inSampleSize=2; return b; } catch (IOException e) { throw new RuntimeException(e); } // return null; }

Solution2: You could deliver it conditionally by apache mod rewrite, php or javascript -takeoff(?): google does not like it? will google ever try pages with a standard users's useragent and compare? -takeoff: The hidden content will be missing in the google cache version as well... example: add-header.php: <?php $path = $_GET['path']; echo file_get_contents($_SERVER["DOCUMENT_ROOT"].$path); ?> apache virtual host config: RewriteCond %{HTTP_USER_AGENT} !.*spider.* [NC] RewriteCond %{HTTP_USER_AGENT} !Yahoo.* [NC] RewriteCond %{HTTP_USER_AGENT} !Bing.* [NC] RewriteCond %{HTTP_USER_AGENT} !Yandex.* [NC] RewriteCond %{HTTP_USER_AGENT} !Baidu.* [NC] RewriteCond %{HTTP_USER_AGENT} !.*bot.* [NC] RewriteCond %{SCRIPT_FILENAME} \.htm$ [NC,OR] RewriteCond %{SCRIPT_FILENAME} \.html$ [NC,OR] RewriteCond %{SCRIPT_FILENAME} \.php$ [NC] RewriteRule ^(.*)$ /var/www/add-header.php?path=%1 [L]

  • mysql_real_escape_string() just makes an empty string?

    - by James P
    I am using a jQuery AJAX request to a page called like.php that connects to my database and inserts a row. This is the like.php code: <?php // Some config stuff define(DB_HOST, 'localhost'); define(DB_USER, 'root'); define(DB_PASS, ''); define(DB_NAME, 'quicklike'); $link = mysql_connect(DB_HOST, DB_USER, DB_PASS) or die('ERROR: ' . mysql_error()); $sel = mysql_select_db(DB_NAME, $link) or die('ERROR: ' . mysql_error()); $likeMsg = mysql_real_escape_string(trim($_POST['likeMsg'])); $timeStamp = time(); if(empty($likeMsg)) die('ERROR: Message is empty'); $sql = "INSERT INTO `likes` (like_message, timestamp) VALUES ('$likeMsg', $timeStamp)"; $result = mysql_query($sql, $link) or die('ERROR: ' . mysql_error()); echo mysql_insert_id(); mysql_close($link); ?> The problematic line is $likeMsg = mysql_real_escape_string(trim($_POST['likeMsg']));. It seems to just return an empty string, and in my database under the like_message column all I see is blank entries. If I remove mysql_real_escape_string() though, it works fine. Here's my jQuery code if it helps. $('#like').bind('keydown', function(e) { if(e.keyCode == 13) { var likeMessage = $('#changer p').html(); if(likeMessage) { $.ajax({ cache: false, url: 'like.php', type: 'POST', data: { likeMsg: likeMessage }, success: function(data) { $('#like').unbind(); writeLikeButton(data); } }); } else { $('#button_container').html(''); } } }); All this jQuery code works fine, I've tested it myself independently. Any help is greatly appreciated, thanks.

  • HTTP Handler error when downloading files - SSL

    - by Chiefy
    Ok big problem as this is affecting two projects on our new server. We have a file that is downloaded by users, the files are downloaded using a HTTPHandler. Since moving the site to the server and setting SSL the downloads have stopped working and we get an error message "Unable to download DownloadDocument.ashx" from site". DownloadDocument.ashx is the handler page that is set in the web.config and the button that goes there is a hyperlink with the id of the document as a querystring. Ive read the article on http://support.microsoft.com/kb/316431 and read a few other requests on this site but nothing seems to be working. This problem only happens in IE and works fine when I run it on the server in http instead of https. public override void HandleRequest(HttpContext context) { Guid guid = new Guid(context.Request.QueryString["ID"]); DataTable dt = Documents.GetDocument(guid); if (dt != null) { context.Response.Cache.SetCacheability(HttpCacheability.Private); context.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", dt.Rows[0]["DocumentName"].ToString())); context.Response.AddHeader("Content-Transfer-Encoding", "binary"); context.Response.AddHeader("Content-Length", ((byte[])dt.Rows[0]["Document"]).Length.ToString()); context.Response.ContentType = string.Format("application/{0}", dt.Rows[0]["Extension"].ToString().Remove(0, 1)); context.Response.Buffer = true; context.Response.BinaryWrite((byte[])dt.Rows[0]["Document"]); context.Response.Flush(); context.Response.End(); } } The above is my current code for the request. Ive used the base handler on http://haacked.com/archive/2005/03/17/AnAbstractBoilerplateHttpHandler.aspx. Any ideas on what this might be and how we can fix it. Thanks in advance for all responses.

  • Unit testing code which uses Umbraco v4 API

    - by Jason Evans
    I'm trying to write a suite of integration tests, where I have custom code which uses the Umbraco API. The Umbraco database lives in a SQL Server CE 4.0 database (*.sdf file) and I've managed to get that association working fine. My problem looks to be dependancies in the Umbraco code. For example, I would like to create a new user for my tests, so I try: var user = User.MakeNew("developer", "developer", "mypassword", "[email protected]", adminUserType); Now as you can see, I have pass a user type which is an object. I've tried two separate ways to create the user type, both of which fail due to a null object exception: var adminUserType = UserType.GetUserType(1); var adminUserType2 = new UserType(1); The problem is that in each case the UserType code calls it's Cache method which uses the HttpRuntime class, which naturally is null. My question is this: Can someone suggest a way of writing integration tests against Umbraco code? Will I have to end up using a mocking framework such as TypeMock or JustMock?

  • Simple way of getting the Last.fm artist image for recently listened songs?

    - by animuson
    On the Last.fm website, your recently listened track include the 34x34 (or whatever size) image at the left of each song. However, in the RSS feed that they give you, no image URLs are provided for the songs. I was wondering if there was a good way of figuring out the ID for the image that needs to be used for that artist and displaying it based on the data that we're given. I know it is possible to load the artist page from their website and then grab the image values from JavaScript, but that seems overly complicated and would probably take quite some time to do. What we're given: <item> <title>Owl City – Rainbow Veins</title> <link>http://www.last.fm/music/Owl+City/_/Rainbow+Veins</link> <pubDate>Thu, 20 May 2010 18:15:29 +0000</pubDate> <guid>http://www.last.fm/user/animuson#1274379329</guid> <description>http://www.last.fm/music/Owl+City</description> </item> and the 34x34 image for this song would be here (ID# 37056785). Does anything like this exist? I've considered storing the ID number in a cache of some sort once it has been checked once, but what if the image changes?

  • Online file storage similar to Amazon S3

    - by Joel G
    I am looking to code a file storage application in perl similar to amazon s3. I already have a amazon s3 clone that I found online called parkplace but its in ruby and is old also isn't built for high loads. I am not really sure what modules and programs I should use so id like some help picking them out. My requirements are listed below (yes I know there are lots but I could start simple then add more once I get it going): Easy API implementation for client side apps. (maybe RESTful but extras like mkdir and cp (?) Centralized database server for the USERDB (maybe PostgreSQL (?). Logging of all connections, bandwidth used, well pretty much everything to a centralized server (maybe PostgreSQL again (?). Easy server side configuration (config file(s) stored on the servers). Web based control panel for admin(s) and user(s) to show logs. (could work just running queries from the databases) Fast High Uptime Low memory usage Some sort of load distribution/load balancer (maybe a dns based or pound or perlbal or something else (?). Maybe a cache of some sort (memcached or parlbal or something else (?). Thanks in advance

  • Do you have health checks in your web app or web site?

    - by Pekka
    I have built PHP based "health check" scripts for several projects, but they were always custom-made for the occasion and not written for abstraction as an independent product. I would like to know whether such a solution exists. What I meam by "health check" is a protected web page that functions much like a suite of unit tests, but on a more operational level, showing red/yellow/green statuses for things like Are the cache directories writable? Is the PHP version correct, are required extensions installed? Is the configuration file protected from writing? Is the database server reachable? Do the key tables exist in the database? Is there enough disk space available? Is the site's front page reachable and renders fully ( = no PHP errors)? Do the project's libraries' MD5 checksums match the original ones? Do you do this - or parts of it - in your applications and web sites? Are there any standardized tools for this that bring along all the functionality to perform the tests (ideally as plugins), and just need to be configured accordingly? Is there a way to set this up using one of the Unit Testing frameworks available for PHP (preferably PHPUnit)? If so, do you know any resources / tutorials outlining how?
