• Get the SEF URLs for articles in joomla

  - by DMin

  Hi, I use no-editor in joomla with SEF urls enabled. With no SEF enabled its easy to know the URL by just getting the ID of the article something like : Article 1 would be : http://www.abc.com/j15/index.php?option=com_content&view=article&id=1&Itemid=1 Now if I have SEF switched on I would get urls that look like: http://www.abc.com/j15/the-content.html Is there a way inside joomla where I can findout what the SEF URL for a particular page is? Currently I add these articles to a menu, then from the front-end I get the SEF URL and then use it. I know the process is a little dumb but I want to find-out if there is a better way inside joomla where you can get the SEF URL(using no-editor). Thanks! :)

• Getting anchor text from a webpage using xpath within YQL

  - by Matt

  SELECT content FROM html WHERE url="http://en.wikipedia.org/wiki/List_of_United_States_National_Parks_by_state" AND xpath="//a/text()" does not work, whereas SELECT * FROM html WHERE url="http://en.wikipedia.org/wiki/List_of_United_States_National_Parks_by_state" AND xpath="//a/text()" does. SELECT content FROM html WHERE url="http://en.wikipedia.org/wiki/List_of_United_States_National_Parks_by_state" AND xpath="//a" also works, it seems YQL has a bug, or am I missing something?

• Help creating custom iPhone Classes

  - by seanny94

  This should be a simple question, but I just can't seem to figure it out. I'm trying to create my own class which will provide a simpler way of playing short sounds using the AudioToolbox framework as provided by Apple. When I import these files into my project and attempt to utilize them, they just don't seem to work. I was hoping someone would shed some light on what I may be doing wrong here. simplesound.h #import <Foundation/Foundation.h> @interface simplesound : NSObject { IBOutlet UILabel *statusLabel; } @property(nonatomic, retain) UILabel *statusLabel; - (void)playSimple:(NSString *)url; @end simplesound.m #import "simplesound.h" @implementation simplesound @synthesize statusLabel; - (void)playSimple:(NSString *)url { if (url = @"vibrate") { AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); statusLabel.text = @"VIBRATED!"; } else { NSString *paths = [[NSBundle mainBundle] resourcePath]; NSString *audioF1ile = [paths stringByAppendingPathComponent:url]; NSURL *audioURL = [NSURL fileURLWithPath:audioFile isDirectory:NO]; SystemSoundID mySSID; OSStatus error = AudioServicesCreateSystemSoundID ((CFURLRef)audioURL,&mySSID); AudioServicesAddSystemSoundCompletion(mySSID,NULL,NULL,simpleSoundDone,NULL); if (error) { statusLabel.text = [NSString stringWithFormat:@"Error: %d",error]; } else { AudioServicesPlaySystemSound(mySSID); } } static void simpleSoundDone (SystemSoundID mySSID, void *args) { AudioServicesDisposeSystemSoundID (mySSID); } } - (void)dealloc { [url release]; } @end Does anyone see what I'm trying to accomplish here? Does anyone know how to remedy this code that is supposedly wrong?

• Why am I getting a new session ID on every page fetch in my Perl WWW::Mechanize script?

  - by Phill Pafford

  So I'm scraping a site that I have access to via HTTPS, I can login and start the process but each time I hit a new page (URL) the cookie Session Id changes. How do I keep the logged in Cookie Session Id? #!/usr/bin/perl -w use strict; use warnings; use WWW::Mechanize; use HTTP::Cookies; use LWP::Debug qw(+); use HTTP::Request; use LWP::UserAgent; use HTTP::Request::Common; my $un = 'username'; my $pw = 'password'; my $url = 'https://subdomain.url.com/index.do'; my $agent = WWW::Mechanize->new(cookie_jar => {}, autocheck => 0); $agent->{onerror}=\&WWW::Mechanize::_warn; $agent->agent('Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.3) Gecko/20100407 Ubuntu/9.10 (karmic) Firefox/3.6.3'); $agent->get($url); $agent->form_name('form'); $agent->field(username => $un); $agent->field(password => $pw); $agent->click("Log In"); print "After Login Cookie: "; print $agent->cookie_jar->as_string(); print "\n\n"; my $searchURL='https://subdomain.url.com/search.do'; $agent->get($searchURL); print "After Search Cookie: "; print $agent->cookie_jar->as_string(); print "\n"; The output: After Login Cookie: Set-Cookie3: JSESSIONID=367C6D; path="/thepath"; domain=subdomina.url.com; path_spec; secure; discard; version=0 After Search Cookie: Set-Cookie3: JSESSIONID=855402; path="/thepath"; domain=subdomain.com.com; path_spec; secure; discard; version=0 Also I think the site requires a CERT (Well in the browser it does), would this be the correct way to add it? $ENV{HTTPS_CERT_FILE} = 'SUBDOMAIN.URL.COM'; ## Insert this after the use HTTP::Request...

• Testing file existence using NSURL

  - by Peter Hosey

  Snow Leopard introduced many new methods to use NSURL objects to refer to files, not pathnames or Core Services' FSRefs. However, there's one task I can't find a URL-based method for: Testing whether a file exists. I'm looking for a URL-based version of -[NSFileManager fileExistsAtPath:]. Like that method, it should return YES if the URL describes anything, whether it's a regular file, a directory, or anything else. I could attempt to look up various resource values, but none of them are explicitly guaranteed to not exist if the file doesn't, and some of them (e.g., NSURLEffectiveIconKey) could be costly if it does. I could just use NSFileManager's fileExistsAtPath:, but if there's a more modern method, I'd prefer to use that. Is there a simple method or function in Cocoa, CF, or Core Services that's guaranteed/documented to tell me whether a given file (or file-reference) URL refers to a file-system object that exists?

• C# Persistent WebClient

  - by Nullstr1ng

  I have a class written in C# (Windows Forms) It's a WebClient class which I intent to use in some website and for Logging In and navigation. Here's the complete class pastebin.com (the class has 197 lines so I just use pastebin. Sorry if I made a little bit harder for you to read the class, also below this post) The problem is, am not sure why it's not persistent .. I was able to log in, but when I navigate to other page (without leaving the domain), I was thrown back to log in page. Can you help me solving this problem? one issue though is, the site I was trying to connect is "HTTPS" protocol. I have not yet tested this on just a regular HTTP.

  Hi, I am wondering what the best way to obtain the current domain is in ASP.NET? For instance: http://www.domainname.com/subdir/ should yield http://www.domainname.com http://www.sub.domainname.com/subdir/ should yield http://sub.domainname.com As a guide, I should be able to add a url like "/Folder/Content/filename.html" (say as generated by Url.RouteUrl() in ASP.NET MVC) straight onto the URL and it should work.

  Once a member signs up a form they can download the pdf file. Currently, the pdf file is link with HTML which means that anyone with the url can download it.

• Parse URLs of major video streaming sites and generate appropriate code for embedding.

  - by Markus Lux

  Posting a video on tumblr.com allows you to just paste the URL of the video on youtube, vimeo, whatever and tumblr automatically does the embedding for you. I assume that this would be nothing more than a mapping between an URL-regex and the belonging HTML construct for embedding the video. Or it is just parsing the response of the URL and getting the construct from there. Is there already any utility, preferably in Java, for doing this? If not, how would you do it?

• How can I autoclean my gnome main menu?

  - by Bruce Connor

  I like to experiment with lots of different software in my Ubuntu install. Then, every time Ubuntu reaches a new release cycle, I simply do a clean install (instead of upgrading) to get rid of all the extra software (and their respective config files/folders). The only thing I always backup and carry to the next install (besides personal files) are the config files for gnome, so my desktop is always the way I like it. =) The problem with that, is that the different packages I test out never get properly uninstalled, so my gnome main menu is full of broken links referring to software I had in previous installations (which got carried over because I kept the gnome config files). Is there any automated way to go through my gnome main menu and remove any broken links? I know how to manually edit the menu, and I could go through it myself, but I'm looking for some script or package that will clean for me so I wouldn't have to do it manually every release cycle.

• Extracting main article from webpage/feed. Is it legal/ethical?

  - by Mahdi Ghiasi

  There are some applications like Readability and Pocket, which are letting users to read the main content of web pages, in a clean interface or such. But the articles should be bookmarked from another application, or the web browser. However, I'm creating a news reader app (Zite and Flipboard are popular news reader apps), and I want to create a clean experience for users, so I want to show full content of articles inside my application. Some websites have fulltext feeds, and I'm using it. But about some other websites, which don't have full text feeds: I want to know, is it legal/ethical to use for example Readability API (Or maybe writing my own code for this) to show full text of articles inside my application?

• Create two semi-transparent images that when stacked produce the target image

  - by posfan12

  Due to CSS limitations I am forced to stack to semi-transparent images on my website. I won't go into detail regarding the CSS since if I can get this question answered the problem is moot. Anyway, I would like to modify image A in the GIMP such that it will look like it did originally after being stacked on top of image B. Both image A and image B have their opacities set to 50%. Image B is a solid color throughout, whereas image A has some minor details such as a gradient. Here's what it looks like before image B is applied on top (and what it should look like in the end): [URL=http://s421.photobucket.com/albums/pp292/SharkD2161/Support/Website/?action=view&current=website_testing_target_image.png][IMG]http://i421.photobucket.com/albums/pp292/SharkD2161/Support/Website/th_website_testing_target_image.png[/IMG][/URL] Here's what it looks like after image B has been applied on top: [URL=http://s421.photobucket.com/albums/pp292/SharkD2161/Support/Website/?action=view&current=website_testing_undesired_result.png][IMG]http://i421.photobucket.com/albums/pp292/SharkD2161/Support/Website/th_website_testing_undesired_result.png[/IMG][/URL] Thanks!

• Display using QtWebKit, whilst parsing xml

  - by Beren Scott

  I wish to use QtWebKit to load a url for display, but, that's the easy part, I can do that. What I wish to do is record / log xml as I go. My attention here is to record and database certain details on the fly, by recording those details. My problem is, how to do this all on the fly, without requesting the same url from the server twice, once for the xml, and the second time to view the url. My hope here, is to implement a very fast way of recording set data as the user passes over it. Take for example, rather then have to type out details displayed by a website, I wish to have those details chucked into a database as I the user views the website. Now, I am using QtWebKit, and I have everything pretty much solved viewing wise. I have a loadUrl() routine which calls load(url) inside the qwebview.h The problem is, how do I piggyback xml parsing on top of this?

What I want to find out is a way to force .net to create another session id instead of using the one that came with url. Is it possible?

• Which specific practices could be called "software craftsmanship" rather than "software engineering"?

  - by FinnNk

  Although not a new idea there seems to have been a big increase in the interest in software craftsmanship over the last couple of years (notably the often recommended book Clean Code's full title is Clean Code: A Handbook of Agile Software Craftsmanship). Personally I see software craftsmanship as good software engineering with an added interest in ensuring that the end result is a joy to work with (both as an end user and as someone maintaining that software) - and also that its focus is more at the coding level of things than the higher level process things. To draw an analogy - there were lots of buildings constructed in the 50s and 60s in a very modern style which took very little account of the people who would be living in them or how those buildings would age over time. Many of those buildings rapidly developed into slums or have been demolished long before their expected lifespans. I'm sure most developers with a few years under their belts will have experienced similar codebases. What are the specific things that a software craftsman might do that a software engineer (possibly a bad one) might not?

• Unable to control requests for static files on Google App Engine

  - by dan

  My simple GAE app is not redirecting to the /static directory for requests when url is multiple levels. Dir structure: /app/static/css/main.css App: I have two handlers one for /app and one for /app/new app.yaml: handlers: - url: /static static_dir: static - url: /app/static/(.*) static_dir: static\1 - url: /app/.* script: app.py login: required HTML: Description: When page is loaded from /app HTTP request for main.css is successful GET /static/css/main.css But when page is loaded from /app/new I see the following request: GET /app/static/css/main.cs That's when I tried adding the /app/static/(.*) in the app.yaml but it is not having any effect.

• Django Template For Loop Removing <img> Self-Closing

  - by Zack

  Django's for loop seems to be removing all of my <img> tag's self-closing...ness (/>). In the Template, I have this code: {% for item in item_list %} <li> <a class="left" href="{{ item.url }}">{{ item.name }}</a> <a class="right" href="{{ item.url }}"> <img src="{{ item.icon.url }}" alt="{{ item.name }} Logo." /> </a> </li> {% endfor %} It outputs this: <li> <a class="left" href="/some-url/">This is an item</a> <a class="right" href="/some-url/"> <img src="/media/img/some-item.jpg" alt="This is an item Logo."> </a> </li> As you can see, the <img> tag is no longer closed, and thus the page doesn't validate. This isn't a huge issue since it'll still render properly in all browsers, but I'd like to know how to solve it. I've tried wrapping the whole for loop in {% autoescape off %}...{% endautoescape %} but that didn't change anything. All other self-closed <img> tags in the document outside the for loop still properly close.

• Extracting URLs (to array) in Ruby

  - by FearMediocrity

  Good afternoon, I'm learning about using RegEx's in Ruby, and have hit a point where I need some assistance. I am trying to extract 0 to many URLs from a string. This is the code I'm using: sStrings = ["hello world: http://www.google.com", "There is only one url in this string http://yahoo.com . Did you get that?", "The first URL in this string is http://www.bing.com and the second is http://digg.com","This one is more complicated http://is.gd/12345 http://is.gd/4567?q=1", "This string contains no urls"] sStrings.each do |s| x = s.scan(/((http|https):\/\/[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(([0-9]{1,5})?\/.[\w-]*)?)/ix) x.each do |url| puts url end end This is what is returned: http://www.google.com http .google nil nil http://yahoo.com http nil nil nil http://www.bing.com http .bing nil nil http://digg.com http nil nil nil http://is.gd/12345 http nil /12345 nil http://is.gd/4567 http nil /4567 nil What is the best way to extract only the full URLs and not the parts of the RegEx? Thanks Jim
