• Is jQuery forcing Adobe ColdFusion to abandon the dead flash product line?

  - by crosenblum

  I have been reading a lot about how flash development/design had died, and as jQuery and in the near future html5 comes out, will this start to push Adobe/Coldfusion away from flash towards less product linking? I mean, I love coldfusion, and want that to continue to grow, however, if Adobe only bought Coldfusion from Macromedia, so they can bundle flash and coldfusion together, does the death of flash mean the death of coldfusion? http://topnews.us/content/221385-jobs-says-adobes-flash-waning-and-had-its-day http://aext.net/2010/03/javascript-jquery-killing-flash-tutorial-jquery-plugin/ I really don't mind if Flash dies, I do mind greatly if coldfusion does. Is the success of Flash linked to Coldfusion? If so, why? or why not? The purpose of this isn't to start some war about flash pro's and con's. I was only worried that Adobe would cause problems for Coldfusion, if flash had some market/financial problems. That was my main concern... And no I am not anti-flash... But my financial sanity depends on Coldfusion being a success, so that is why I stated my question. Because I WANT EVERYONE ELSE'S OPINION OF THIS SITUATION. Thank You.

• How to troubleshoot memcache set method always fail issue?

  - by Morgan Cheng

  I have XAMPP 1.7.3 installed on Windows 7. The PHP version is 5.3.1. I have successfully installed memcache for win32 from http://www.splinedancer.com/memcached-win32. I got PHP extension php_memcache.dll from http://downloads.php.net/pierre. Restarting apache and checking phpinfo() shows memcache is OK. When I test it with below PHP page. It always fail in set method. <?php $memcache = new Memcache; $memcache->connect('127.0.0.1', 11211) or die ("Could not connect"); $version = $memcache->getVersion(); echo "Server's version: ".$version." \n"; $tmp_object = new stdClass; $tmp_object->str_attr = 'test'; $tmp_object->int_attr = 123; $memcache->set('key', $tmp_object, false, 10) or die ("Failed to save data at the server"); echo "Store data in the cache (data will expire in 10 seconds)\n"; $get_result = $memcache->get('key'); echo "Data from the cache: \n" ?> The set method always return false so it constantly output Server's version: Failed to save data at the server I'm stuck. I don't know which way to trouble shoot this issue. Anybody has any idea about possible direction? Thanks.

• PNG Transparency Problems in IE8

  - by user138777

  I'm having problems with a transparent PNG image showing black dithered pixel artifacts around the edge of the non transparent part of the image. It only does this in Internet Explorer and it only does it from a Javascript file it is used in. Here's what I'm talking about... http://70.86.157.71/test/test3.htm (link now dead) ...notice the girl in the bottom right corner. She has artifacts around her in IE8 (I haven't tested it in previous versions of IE, but I'm assuming it probably does the same). It works perfectly in Firefox and Chrome. The image is loaded from a Javascript file to produce the mouseover effect. If you load the image all by itself, it works fine. Here's the image... http://70.86.157.71/test/consultant2.png Does anyone know how to fix this? The image was produced in Photoshop CS3. I've read things about removing the Gama, but that apparently was in previous versions of Photoshop and when I load it in TweakPNG, it doesn't have Gama. Please help!

• Replacing content with jquery.

  - by BillZ

  I am loading a movie into a overlay. My problem is that when I close the div overlay the movie continues to play. I do not control the code on the move side it is imported via a script tag which then opens in a iframe. I am able to remove the content of the of the div and then the movie stops playing. Then of course when the user opens the div again the movie is gone. My current thinking was that I could simply replace the script tag with one just like it but the outcome of that is that there is nothing there. I have been using jquery. Thanks -- script -- $(document).ready(function() { $("#closeModal2").click(function() { $("#movieContainer").html("<script src='http://www.accelacast.com/programs/launch.js'/>"); }); }); -- html -- <div id="movieContainer"> <script id="movieTag" language='JavaScript' src='http://www.accelacast.com/programs/launch.js'/> </div> On a side note. I tried replacing the src attribute of the script tag with no luck. I was able to replace the src of a image though. Is it not possible to effect the src attribute of script? Thanks

• Webfaction apache + mod_wsgi + django configuration issue

  - by Dmitry Guyvoronsky

  A problem that I stumbled upon recently, and, even though I solved it, I would like to hear your opinion of what correct/simple/adopted solution would be. I'm developing website using Django + python. When I run it on local machine with "python manage.py runserver", local address is http://127.0.0.1:8000/ by default. However, on production server my app has other url, with path - like "http://server.name/myproj/" I need to generate and use permanent urls. If I'm using {% url view params %}, I'm getting paths that are relative to / , since my urls.py contains this urlpatterns = patterns('', (r'^(\d+)?$', 'myproj.myapp.views.index'), (r'^img/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/img' }), (r'^css/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/css' }), ) So far, I see 2 solutions: modify urls.py, include '/myproj/' in case of production run use request.build_absolute_uri() for creating link in views.py or pass some variable with 'hostname:port/path' in templates Are there prettier ways to deal with this problem? Thank you. Update: Well, the problem seems to be not in django, but in webfaction way to configure wsgi. Apache configuration for application with URL "hostname.com/myapp" contains the following line WSGIScriptAlias / /home/dreamiurg/webapps/pinfont/myproject.wsgi So, SCRIPT_NAME is empty, and the only solution I see is to get to mod_python or serve my application from root. Any ideas?

• I need some pointers on how to implement inertia

  - by gargantaun

  Ok, so I've created a little plugin that takes a bunch of elements and creates a sort of never ending list. I'll try to explain... I have a div, and it's got about 20 elements tags in it. When the user scrolls up, the top element moves out of view and is moved to the bottom of the list. And vice-versa so that when the user scrolls down, the bottom element is moved to the top of the list. This is specifically for Mobile Safari (iPad, iPhone) web content and you can see the work in progress here... http://appliedworks.co.uk/files/times/SVGTests/drumView/drum.html You'll need an iPad or iPhone top see the scrolling in action. You can see the plugin code here... http://appliedworks.co.uk/files/times/SVGTests/drumView/drumView-0.1b.js What I would like to do is implement inertia so the scrolling slows to a halt in response to how fast or slow the user is scrolling when their finger leaves the screen. Just like the inertia commonly found in the iPhone / iPad UI. The problem is, every time an element moves to the top or the bottom of the list, the scollTop value for the parent div is adjusted to make it look like all the elements are staying in the same place. Which means the scrollTop value is never more than the top elements total height. So there's no value I can think of that I can keep on manipulating to give the illusion of inertia. I'm stumped. Does anyone have any suggestions?

• HTML + CSS: fixed background image and body width/min-width (including fiddle)

  - by insertusernamehere

  So, here is my problem. I'm kinda stuck at the moment. I have a huge background image and content in the middle with those attributes: content is centered with margin auto and has a fixed width the content is related to the image (like the image is continued within the content) this relation is only horizontally (vertically scrolling moves everything around) This works actually fine (I'm only talking desktop, not mobile here :) ) with a position fixed on the huge background image. The problem that occurs is the following: When I resize the window to "smaller than the content" the background image gets it width from the body instead of the viewport. So the relation between content and image gets lost. Now I have this little JavaScript which does the trick, but this is of course some overhead I want to avoid: $(window).resize(function(){ img.css('left', (body.width() - img.width()) / 2 ); }); This works with a fixed positioned image, but can get a litty jumpy while calculating. I also tried things like that: <div id="test" style=" position: absolute; z-index: 0; top: 0; left: 0; width: 100%: height: 100%; background: transparent url(content/dummy/brand_backgroud_1600_1.jpg) no-repeat fixed center top; "></div> But this gets me back to my problem described. Is there any "script-less", elegant solution for this problem? UPDATE: now with Fiddle The one I'm trying to solve: http://jsfiddle.net/insertusernamehere/wPmrm/ The one with Javascript that works: http://jsfiddle.net/insertusernamehere/j5E8z/ NOTE The image size is always fixed. The image never gets scaled by the browser. In the JavaScript example it get's blown. So don't care about the size.

• Is there a faster way to parse through a large file with regex quickly?

  - by Ray Eatmon

  Problem: Very very, large file I need to parse line by line to get 3 values from each line. Everything works but it takes a long time to parse through the whole file. Is it possible to do this within seconds? Typical time its taking is between 1 minute and 2 minutes. Example file size is 148,208KB I am using regex to parse through every line: Here is my c# code: private static void ReadTheLines(int max, Responder rp, string inputFile) { List<int> rate = new List<int>(); double counter = 1; try { using (var sr = new StreamReader(inputFile, Encoding.UTF8, true, 1024)) { string line; Console.WriteLine("Reading...."); while ((line = sr.ReadLine()) != null) { if (counter <= max) { counter++; rate = rp.GetRateLine(line); } else if(max == 0) { counter++; rate = rp.GetRateLine(line); } } rp.GetRate(rate); Console.ReadLine(); } } catch (Exception e) { Console.WriteLine("The file could not be read:"); Console.WriteLine(e.Message); } } Here is my regex: public List<int> GetRateLine(string justALine) { const string reg = @"^\d{1,}.+\[(.*)\s[\-]\d{1,}].+GET.*HTTP.*\d{3}[\s](\d{1,})[\s](\d{1,})$"; Match match = Regex.Match(justALine, reg, RegexOptions.IgnoreCase); // Here we check the Match instance. if (match.Success) { // Finally, we get the Group value and display it. string theRate = match.Groups[3].Value; Ratestorage.Add(Convert.ToInt32(theRate)); } else { Ratestorage.Add(0); } return Ratestorage; } Here is an example line to parse, usually around 200,000 lines: 10.10.10.10 - - [27/Nov/2002:16:46:20 -0500] "GET /solr/ HTTP/1.1" 200 4926 789

• Are mathematical Algorithms protected by copyright?

  - by analogy

  I wish to implement an algorithm which i read in a journal paper in my software (commercial). I want to know if this is allowed or not. The algorithm in question is described in http://arxiv.org/abs/0709.2938 It is a very simple algorithm and a number of implementations exist in python (http://igraph.sourceforge.net/) and java. One of them is in gpl another which i got from a different researcher and had no license attached. There are significant differences in two implementations, e.g. second one uses threads and multiple cores. It is possible to rewrite/ (not translate) the algorithm. So can I use it in my software or on a server for commercial purpose. Thanks UPDATE: I am completely aware of copyright on the text of paper, it was published in phys rev E. I am concerned with use of the algorithm, in commercial software. Also the publication means that unless the patent has been already filed. The method has been disclosed publicly hence barring patent in future. Also the GPL implementation is not by authors themselves but comes from a third party. Finally i am not using the GPL implementation but creating my own using C++.

• The rules to connect a web service trough the SSL and Certificates

  - by blgnklc

  There is a web service running on tomcat on a server. It is built on Java Servlet. It is listening others to call itself on a SSL enabled http port. so its web service adreess looks like: https://172.29.12.12/axis/services/XYZClient?wsdl On the other hand I want to connect the web service above from a windows application which is built on .NET frame work. Finally, when I want to connect the web service from my computer; I get some specific erros; Firstly I get; Proxy authentication error; then I added some new line to my code; Dim cr As System.Net.NetworkCredential = New System.Net.NetworkCredential("xname", "xsurname", "xdomainname") Dim myProxy As New WebProxy("http://mar.xxxyyy.com", True) myProxy.Credentials = cr Secondly, after this modifications It says that bad request. I did not get over this error. Moreover I did try to connect the web server on the same computer. I copied my executable program to the computer where the web service runs. The error was like; The underlying connection was closed: Could not establish trust relationship for SSL/TLS secure channel PS: When I try to connect to web service by using Internet Explorer; I see firstly some warnings about accepting an unknown certificate and I click take me to web service an I get there clearly.

• Inserting javascript with jQuery .html

  - by Andrew Appleby

  I'm experiencing an issue with a website I'm working on, where I originally believed I could simply replace $("main").html('THIS') which was originally code for a flash object, with a new and improved HTML5/Javascript version. The original code: $("#main").html('<div style="height: 100%; width: 100%; overflow: hidden;"><object width="100%" height="100%" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000">\ <param value="images/uploads/'+image_id+'.swf" name="movie">\ <param value="true" name="allowFullScreen">\ <param value="#737373" name="bgcolor">\ <param value="" name="FlashVars">\ <embed width="100%" height="100%" flashvars="" bgcolor="#737373" allowfullscreen="true" src="images/uploads/'+image_id+'.swf" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer">\ </object></div>\ '); }); And my (failed) attempt at inserting my new code: $("#main").html('<script type="text/javascript">pano=new pano2vrPlayer("container");skin=new pano2vrSkin(pano);pano.readConfigUrl("xml/tablet_'+image_id+'.xml");hideUrlBar();</script>'); It doesn't even work when I just put , so I know it's gotta be the javascript itself. I've looked at the solutions out there, but I can't make sense in how to properly implement them here in the most efficient way. Your help is much appreciated, thanks!

• Rails Binary Stream support

  - by Craig Walker

  I'm going to be starting a project soon that requires support for large-ish binary files. I'd like to use Ruby on Rails for the webapp, but I'm concerned with the BLOB support. In my experience with other languages, frameworks, and databases, BLOBs are often overlooked and thus have poor, difficult, and/or buggy functionality. Does RoR spport BLOBs adequately? Are there any gotchas that creep up once you're already committed to Rails? BTW: I want to be using PostgreSQL and/or MySQL as the backend database. Obviously, BLOB support in the underlying database is important. For the moment, I want to avoid focusing on the DB's BLOB capabilities; I'm more interested in how Rails itself reacts. Ideally, Rails should be hiding the details of the database from me, and so I should be able to switch from one to the other. If this is not the case (ie: there's some problem with using Rails with a particular DB) then please do mention it. UPDATE: Also, I'm not just talking about ActiveRecord here. I'll need to handle binary files on the HTTP side (file upload effectively). That means getting access to the appropriate HTTP headers and streams via Rails. I've updated the question title and description to reflect this.

• Which is more secure GET or POST sending parameters with cURL at PHP

  - by Steve

  I want to connect in a secure way with an API and I am using cURL to do it using HTTPS and SSL. Now, i was wondering what is better in terms of security, sending the data through GET or POST: $ch = curl_init("http://api.website.com/connect.php?user=xxx&pass=xxxx); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); $result = curl_exec($ch); curl_close($ch); Or $param['user'] = 'xxxx'; $param['pass'] = 'xxxx'; $ch = curl_init("http://api.website.com/connect.php); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $Parameters); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); $result = curl_exec($ch); curl_close($ch); I also realized that POST is much more slower retrieving the data.

Below is the code that works great for text that contains no special characters, but can you show me how and where to change the code to allow for the special characters to be used. Right now those characters crash the app. enter code here - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{ if (buttonIndex == 1) { //iTunes Audio Search NSString *stringURL = [NSString stringWithFormat:@"http://phobos.apple.com/WebObjects/MZSearch.woa/wa/search?WOURLEncoding=ISO8859_1&lang=1&output=lm&term=\"%@\"",currentSong.title]; stringURL = [stringURL stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]; NSURL *url = [NSURL URLWithString:stringURL]; [[UIApplication sharedApplication] openURL:url]; } } And this: -(IBAction)launchLyricsSearch:(id)sender{ WebViewController * webView = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:[NSBundle mainBundle]]; webView.webURL = [NSString stringWithFormat:@"http://www.google.com/m/search?hl=es&q=\"%@\"+letras",currentSong.title]; webView.webTitle = @"Letras"; [self.navigationController pushViewController:webView animated:YES]; } Please show me how and where to do this for these two bits of code.

• XML Schema: How to specify an attribute with a custom 'simpleType' type?

  - by mackenir

  In my XML schema definition, I'm trying to restrict the value of an attribute to be an integer between 0 and 100. With reference to the sample schema below, I want attribute 'attr' on element 'root' to have this restriction. To achieve this I define a simpleType 'Percentage' and set this as the 'type' of 'attr'. However, my XML schema editor (VS 2008) flags the attribute up as having a problem: "Type 'Percentage' is not declared or is not a simple type". <?xml version="1.0" encoding="utf-8"?> <xs:schema elementFormDefault="qualified" id="test" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://testtttt"> <xs:simpleType name="Percentage"> <xs:restriction base="xs:integer"> <xs:minInclusive value="0"/> <xs:maxInclusive value="100"/> </xs:restriction> </xs:simpleType> <xs:element name="root"> <xs:complexType> <xs:attribute name="attr" type="Percentage" use="optional" /> </xs:complexType> </xs:element>

• Sending JSON to a server

  - by SK9

  I'm running the following Java, an HttpURLConnection PUT request with JSON data that will be sent from an Android device. I'll handle any raised exceptions after this is working. Authenticator.setDefault(new Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(nameString, pwdString.toCharArray()); } }); url = new URL(myURLString); HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); urlConnection.setDoOutput(true); urlConnection.setChunkedStreamingMode(0); urlConnection.setRequestMethod("PUT"); urlConnection.setRequestProperty("Content-Type", "application/json"); OutputStream output = null; try { output = urlConnection.getOutputStream(); output.write(jsonArray.toString().getBytes()); } finally { if (output != null) { output.close(); } } int status = ((HttpURLConnection) urlConnection).getResponseCode(); System.out.println("" + status); urlConnection.disconnect(); I'm receiving an HTTP 500 error (internal error code), that an unexpected property is blocking the request. The JSONArray comprises JSONObjects whose keys I know are correct. The server is pretty standard, and expects HTTP PUTs with JSON bodies. Am I missing something glaring? Thanking you kindly in advance.

• How can I change Rails view code for site visitors using SSL?

  - by pjmorse

  My Rails app has some pages which are SSL-required and others which are SSL-optional. The optional pages use some assets which are served off-site (images from a vendor) which have both http and https URLs. I need to use https when the page is accessed via SSL to avoid the dreaded "this page contains both secure and insecure elements" warning. I've written code to return the image URLs as http by default and https if requested. My problem now is determining in the view how the request came in. request.ssl? doesn't work in views. I've tried using a before_filter which sets something like @ssl_request using request.ssl?, but that also always returns false. Is there a more elegant way to do this? The server stack is Nginx and Passenger. Other apps with Apache = Mongrel stacks pass an X_FORWARDED_PROTO header to tell Rails that SSL is or isn't being used; is it possible that Nginx/Passenger doesn't do this?

• Downloading a picture via urllib and python.

  - by Mike

  So I'm trying to make a Python script that downloads webcomics and puts them in a folder on my desktop. I've found a few similar programs on here that do something similar, but nothing quite like what I need. The one that I found most similar is right here (http://bytes.com/topic/python/answers/850927-problem-using-urllib-download-images). I tried using this code: >>> import urllib >>> image = urllib.URLopener() >>> image.retrieve("http://www.gunnerkrigg.com//comics/00000001.jpg","00000001.jpg") ('00000001.jpg', <httplib.HTTPMessage instance at 0x1457a80>) I then searched my computer for a file "00000001.jpg", but all I found was the cached picture of it. I'm not even sure it saved the file to my computer. Once I understand how to get the file downloaded, I think I know how to handle the rest. Essentially just use a for loop and split the string at the '00000000'.'jpg' and increment the '00000000' up to the largest number, which I would have to somehow determine. Any reccomendations on the best way to do this or how to download the file correctly? Thanks!

• Storing arbitrary data in HTML

  - by Rob Colburn

  What is the best way to embed data in html elements for later use? As an example, let's say we have jQuery returning some JSON from the server, and we want to dump that datat out to the user as paragraphs. However, we want to be able to attach meta-data to these elements, so we can events for these later. The way I tend to handle this, is with some ugly prefixing function handle_response(data) { var html = ''; for (var i in data) { html += '<p id="prefix_' + data[i].id + '">' + data[i].message + '</p>'; } jQuery('#log').html(html).find('p').click(function(){ alert('The ID is: ' + $(this).attr('id').substr(7)); }); } Alternatively, one can build a Form in the paragraph, and store your meta-data there. But, that often feels like overkill. This has been asked before in different ways, but I do not feel it's been answered well: http://stackoverflow.com/questions/432174/how-to-store-arbitrary-data-for-some-html-tags http://stackoverflow.com/questions/209428/non-standard-attributes-on-html-tags-good-thing-bad-thing-your-thoughts
