  • Nokogiri and Special Characters

    - by Moe
    I'm using Nokogiri to grab the contents of the title tag on a webpage, but am having trouble with accented characters. What's the best way to deal with these? Here's what I'm doing: require 'open-uri' require 'nokogiri' doc = Nokogiri::HTML(open(link)) title = doc.at_css("title") At this point, the title looks like this: Rag\303\271 Instead of: Ragù How can I have nokogiri return the proper character (e.g. ù in this case)?

  • Graphics Driver problem, ATI Radeon HD 3200, small screen size and slows everything down.

    - by Arvind Jangid
    Regards. I am using a: 2009 Compaq Presario CQ40-415AU Notebook AMD Athlon X2 Dual core Processor 2.1 GHz 1024 MB L2 cache 3GB DDR2 RAM ATI Radeon + HD 3200 Graphics 256 MB, screen is 14 inch widescreen with resolution of 1280*800. I installed Ubuntu 12.04 LTS 32bit on my laptop. It works brilliantly until I installed graphics driver. When I installed the driver, the graphics became slow. Everything slowed down. Even the splash screen resolution changed to something like 640*480. I have liked Ubuntu since 9.10 and for the freedom it provides and its versatility, but graphics problem remains the same. I even installed Ubuntu on a 50 GB partition with 6 GB swap partition. My HDD is 320 GB. Please tell me what is wrong.

  • How do I render my own DirectX Stuff to a full screen WPF's DirectX surface?

    - by marc40000
    Basically Danny Varod seems to know as he posted it as an answer to this question: Display a Message Box over a Full Screen DirectX application I think, theoretically this might work, but I have no idea how to actually do it. Since I'm also not allowed to post a comment under his comment nor am I allwoed to ask on meta about how to contact another user, I ask this as a normal question here: How do I render my own DirectX Stuff to a full screen WPF's DirectX surface? For starters, I have no idea how to get the DirectX surface from a WPF window. If I had it, what do I have to take care of that the WPF rendering doesn't screw up my own rending or vice-versa?

  • iphone/ipad orientation handling

    - by Mark
    This is more of a general question for people to provide me guidance on, basically Im learning iPad/iPhone development and have finally come across the multi-orientation support question. I have looked up a fair amount of doco, and my book "Beginning iPhone 3 Development" has a nice chapter on it. But my question is this, if I was to programatically change my controls (or even use different views for each orientation) how on earth to people maintain their code base? I can just imagine so many issues with spaghetti code/thousands of "if" checks all over the place, that it would drive me nuts to make one small change to the UI arrangement. Does anyone have experience handling this issue? What is a nice way to control it? Thanks a lot Mark

  • Get Mechanize to handle cookies from an arbitrary POST (to log into https://www.t-mobile.com/ progra

    - by Horace Loeb
    I want to log into https://www.t-mobile.com/ programmatically. My first idea was to use Mechanize to submit the login form: However, it turns out that this isn't even a real form. Instead, when you click "Log in" some javascript grabs the values of the fields, creates a new form dynamically, and submits it. "Log in" button HTML: <button onclick="handleLogin(); return false;" class="btnBlue" id="myTMobile-login"><span>Log in</span></button> The handleLogin() function: function handleLogin() { if (ValidateMsisdnPassword()) { // client-side form validation logic var a = document.createElement("FORM"); a.name = "form1"; a.method = "POST"; a.action = mytmoUrl; // defined elsewhere as https://my.t-mobile.com/Login/LoginController.aspx var c = document.createElement("INPUT"); c.type = "HIDDEN"; c.value = document.getElementById("myTMobile-phone").value; // the value of the phone number input field c.name = "txtMSISDN"; a.appendChild(c); var b = document.createElement("INPUT"); b.type = "HIDDEN"; b.value = document.getElementById("myTMobile-password").value; // the value of the password input field b.name = "txtPassword"; a.appendChild(b); document.body.appendChild(a); a.submit(); return true } else { return false } } I could simulate this form submission by POSTing the form data to https://my.t-mobile.com/Login/LoginController.aspx with Net::HTTP#post_form, but I don't know how to get the resultant cookie into Mechanize so I can continue to scrape the UI available when I'm logged in. Any ideas?

  • How can I fix the website's splash page to work in IE8 and below?

    - by Abriel
    I have been trying to figure out for the longest time how I can get the splash page on this website to work correctly in IE8 and below? Right now, it works on all the other browsers (Firefox, Chrome, Safari). Here is the website: http://gds.parkland.edu/student/fall10/gds220/ashipley/p2/final_revised/index.html jQuery code: /* Sliding Affect Splash Page */ $(function() { $('.box').each(function() { var $this = $(this); $.data(this, 'css', { width: $this.css('width'), background: $this.css('background-image') }); }); }); function restore() { $('.box').each(function() { var orig = $.data(this, 'css'); $(this).animate({ width: orig.width },{queue:false}); $(this).css({backgroundImage: orig.background}); }); } /* box 1 */ function boxHover(){ $('.box').stop().animate({'width' : '596px'},{queue:false}); } function box1master(){ $('.box2').css({backgroundImage: 'url(images/splash/zatgun_midtop.jpg)'}); $('.box3').css({backgroundImage: 'url(images/splash/zatgun_midbottom.jpg)'}); $('.box4').css({backgroundImage: 'url(images/splash/zatgun_bottom.jpg)'}); } function box2master(){ $('.box1').css({backgroundImage: 'url(images/splash/bryan_top.jpg)'}); $('.box3').css({backgroundImage: 'url(images/splash/bryan_midbottom.jpg)'}); $('.box4').css({backgroundImage: 'url(images/splash/bryan_bottom.jpg)'}); } function box3master(){ $('.box1').css({backgroundImage:'url(images/splash/galleries_top.jpg)'}); $('.box2').css({backgroundImage: 'url(images/splash/galleries_midtop.jpg)'}); $('.box4').css({backgroundImage: 'url(images/splash/galleries_bottom.jpg)'}); } function box4master(){ $('.box1').css({backgroundImage: 'url(images/splash/contact_top.jpg)'}); $('.box2').css({backgroundImage: 'url(images/splash/contact_midtop.jpg)'}); $('.box3').css({backgroundImage: 'url(images/splash/contact_midbottom.jpg)'}); } $(document).ready(function(){ $('.box1').hover(function(){ boxHover(); box1master(); }, function(){ restore(); }); $('.box2').hover(function(){ boxHover(); box2master(); }, function(){ restore(); }); $('.box3').hover(function(){ boxHover(); box3master(); }, function(){ restore(); }); $('.box4').hover(function(){ boxHover(); box4master(); }, function(){ restore(); }); }); I wonder if I could change the spacing in-between each of the boxes using jQuery or if I somehow have to do this in the CSS/HTML?

  • Make buttonsize bigger for tablet? Android, Xml

  • Thumbnails from HTML pages created and used automatically in web application

    - by Jesper Rønn-Jensen
    I am working on a Ruby on Rails app that visualizes product trees. The tree is built of nodes an everything is rendered in HTML/CSS3. Some of the products make several hundred SQL queries as the tree builds up (up to 800 queries on the biggest tree). I'd like to have small thumbnails of each tree to present it on an index page. So rendering each tree once again and modifying CSS to make a tiny representation is an option. But i think it's probably easier to generate thumbnails, crop, cache, and show these on the index page. Any ideas on how to do this? Any links/articles/blog posts that could help me?

  • Headless, scriptable Firefox/Webkit on linux?

    - by Parand
    I'm looking to automate some web interactions, namely periodic download of files from a secure website. This basically involves entering my username/password and navigating to the appropriate URL. I tried simple scripting in Python, followed by more sophisticated scripting, only to discover this particular website is using some obnoxious javascript and flash based mechanism for login, rendering my methods useless. I then tried HTMLUnit, but that doesn't seem to want to work either. I suspect use of Flash is the issue. I don't really want to think about it any more, so I'm leaning towards scripting an actual browser to log in and grab the file I need. Requirements are: Run on linux server (ie. no X running). If I really need to have X I can make that happen, but I won't be happy. Be reliable. I want to start this thing and never think about it again. Be scriptable. Nothing too sophisticated, but I should be able to tell the browser the various steps to take and pages to visit. Are there any good toolkits for a headless, X-less scriptable browser? Have you tried something like this and if so do you have any words of wisdom?

  • How to protect/monitor your site from crawling by malicious user

    - by deathy
    Situation: Site with content protected by username/password (not all controlled since they can be trial/test users) a normal search engine can't get at it because of username/password restrictions a malicious user can still login and pass the session cookie to a "wget -r" or something else. The question would be what is the best solution to monitor such activity and respond to it (considering the site policy is no-crawling/scraping allowed) I can think of some options: Set up some traffic monitoring solution to limit the number of requests for a given user/IP. Related to the first point: Automatically block some user-agents (Evil :)) Set up a hidden link that when accessed logs out the user and disables his account. (Presumably this would not be accessed by a normal user since he wouldn't see it to click it, but a bot will crawl all links.) For point 1. do you know of a good already-implemented solution? Any experiences with it? One problem would be that some false positives might show up for very active but human users. For point 3: do you think this is really evil? Or do you see any possible problems with it? Also accepting other suggestions.

  • Web scraping: how to get scraper implementation from text link?

    - by isme
    I'm building a java web media-scraping application for extracting content from a variety of popular websites: youtube, facebook, rapidshare, and so on. The application will include a search capability to find content urls, but should also allow the user to paste a url into the application if they already where the media is. Youtube Downloader already does this for a variety of video sites. When the program is supplied with a URL, it decides which kind of scraper to use to get the content; for example, a youtube watch link returns a YoutubeScraper, a Facebook fanpage link returns a FacebookScraper and so on. Should I use the factory pattern to do this? My idea is that the factory has one public method. It takes a String argument representing a link, and returns a suitable implementation of the Scraper interface. I guess the Factory would hold a list of Scraper implementations, and would match the link against each Scraper until it finds a suitable one. If there is no suitable one, it throws an Exception instead.

  • How would you protect a database of links from being scraped?

    - by Yegor
    I have a large database of links, which are all sorted in specific ways and are attached to other information, which is valuable (to some people). Currently my setup (which seems to work) simply calls a php file like link.php?id=123, it logs the request with a timestamp into the DB. Before it spits out the link, it checks how many requests were made from that IP in the last 5 minutes. If its greater than x, it redirects you to a captcha page. That all works fine and dandy, but the site has been getting really popular (as well as been getting DDOsed for about 6 weeks), so php has been getting floored, so Im trying to minimize the times I have to hit up php to do something. I wanted to show links in plain text instead of thru link.php?id= and have an onclick function to simply add 1 to the view count. Im still hitting up php, but at least if it lags, it does so in the background, and the user can see the link they requested right away. Problem is, that makes the site REALLY scrapable. Is there anything I can do to prevent this, but still not rely on php to do the check before spitting out the link?

  • Any way to trigger interface orientation check?

    My app is going from a flipside view (only one orientation) to its main view (can have any sort of orientation. When I go from flipside back to main view, the main view's orientation is not checked and changed immediately. I need a way to trigger the built in orientation check that happens in willRotateToInterfaceOrientation so that the orientation is correct when the user goes from flipside view to main view. Any help is appreciated. I saw another question about this but didn't see a definitive answer. Thanks!

    Hi, We want to add a facebook fan page photo competition to our fan page. The meaning is that ppl can upload photo's and others can like them. The person with the most likes on his photo wins a price. Now i was wondering if anyone knows a good idea on how to get a snapshot of all the photo's on a given moment. So that when we want to stop the contest we get an overview of the number of likes of all the persons.

  • Problems when handling orientation changes

    - by nixau
    Hi all, I need to handle orientation changes in my Android application. For this purpose I decided to use OrientationEventListener convenience class. But his callback method is given somewhat strange behavior. My application starts in the portrait mode and then eventually switches to the lanscape one. I have some custom code executing in the callback onOrientationChanged method that provides some additional UI handling logic - it has a few calls to findViewById. What is strange is that when switching back from landscape to portrait mode onOrientationChanged callback is called twice, and what's even worse - the second call is dealing with bad Context - findViewById method starts returning null. These calls are made right from the MainThread @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); listener = new OrientationListener(); } @Override protected void onResume() { super.onResume(); // enabling listening listener.enable(); } @Override protected void onPause() { super.onPause(); // disabling listening listener.disable(); } I've replicated the same behavior with a dummy Activity without any logic except for one that deals with orientation hadling. I initiate orientation switch from the Android 2.2 emulator by pressing Ctrl+F11 What could be wrong? Upd: Inner class that implements OrientationEventListener private class OrientationListener extends OrientationEventListener { public OrientationL() { super(getBaseContext()); } @Override public void onOrientationChanged(int orientation) { toString(); } } }

  • How to export scrubyt extractor?

    - by robintw
    I've written a scrubyt extractor based on the 'learning' technique - that is, specifying the current text on the page and getting it to work out the XPath expressions itself. However, I now want to export the extractor so that it can be used even when the page has changed. The documentation for scrubyt seems to be all over the place now, but from what I can find I should be able to put the line extractor.export(__FILE__) and it should work. It doesn't - I just get an error saying that there is the wrong number of arguments for export, it should have 0. I've tried it without any arguments and it still fails. I would ask on the scrubyt forum, but it seems like no-one's been there for ages! Any ideas what to do here?

    - by Bruce McKean
    I'm not a computer nerd but have been able to fix Ubuntu/Linux problems in the pass two years with a Google search but this on has me stumped. I upgraded to 12.04 about thirty days ago and all was well except that every time I tried to load KeePassX it would go to the login screen. I installed KeePass2 and all seemed to work. Last week I tried to load Bibble5 (Raw photo editor) and it would try to load and then back to the login screen. After a few days I gave up and downloaded Corel After Shot Pro (Corel's now owns Bibble5) and it has the same problem. Could someone please head me into the steps I need to follow to find out what is the cause.

  • Why WCAG made 3 level "A", "AA" and "AAA"?

    - by jitendra
    What is the purpose of making 3 priority level by WCAG? is it like? If client not paying extra or if we don't have much time then go for A If client paying then or if we have time to make site compatible go for at least AA If client paying and needed according to govt. rules then go for AAA If we are making site then which level we should we try to achieve, or we should do only on client request? Although i found these definitions on this site but these are confusing for me • Priority 1: For all users to access the Web content and for Web developers to attain Conformance level “A”, these requirements must be satisfied. • Priority 2: These requirements should be satisfied by the Web developers so that no group finds it difficult to access the Web content and so as to attain Conformance level “AA”. • Priority 3: These requirements may be satisfied by the Web developers to facilitate access to Web content for some groups and attain Conformance level “AAA”.
