• How can I select a value matching my input from a TypeAhead control using WWW::Mechanize?

  - by kyoob

  So ordinarily the element I want to pick from a list would be populated on a page and I'd just find it and pick it. But I'm dealing with a control that doesn't populate list elements until some input has been stuck into a text box, after which it gives me a list of recommendations. For an example of the kind of list I'm talking about think of Facebook's "People, Places, and Things" search field. I want to plug a string into this text box, select the same string from the list of recommendations, and submit the form. The issue I'm having right now is I can't seem to get Mechanize to even recognize the field is there. I examine a dump of $mech->find_all_inputs and it isn't listed. Is this kind of field just beyond Mechanize's jurisdiction?

• DotNetOpenAuth I need some help please

  - by Nate Gates

  I know this has been posted before, but never really answered, I'm using the DotNetOpenAuth to try and do GoogleID login, and every time I do details = OResponse.GetExtension<ClaimsResponse>(); I always, always, always get back null, I don't get whats the point of the GoogleID if I can't get back any information, I would think at the very least I would get an email address, so I could associate it other login information in my databse. I just don't understand could really use some help, Im probably just looking at openID in the wrong way. I'm using ASP.NET and looking to use openID/Facebook as my sole means of logging in users, I really don't want to mess with membership roles, or extra junk that ASP.NET likes to add.

• A couple problems re: CodeIgniter emailer

  - by Walker

  I have some problems with the email system for CodeIgniter: First, the emails I send out (registration, confirmations) are getting caught in standard spam filters in gmail and other mail clients. How do I get around this? How do companies like Facebook get their emails through consistently? Second, the mailer is working locally but once we deploy it it no longer runs (doesn't send emails) but all the other forms run just fine. Anyone ever run into a problem like this? Thanks for all the help!

• the News Feed technique

  - by Rawhi

  I have been read a lot of articles to make a good design for my database so I can get the most recent updates for every single user by executing a - kind of - complex query then I send the data using ajax as a JSON to JS file that makes an appropriate edits for the records. It seems fast but I don't know if it will be as much as fast if the site has a large number of users . so iv'e started looking for an alternatives . and I found something called NodeJS , I really didn't understand what it is stand for and hope that you can help me with that. from another hand if the facebook doesn't use a normal db to do whatever he does , then I think there is no way to do it . helpful link : What's the best manner of implementing a social activity stream? waiting for your comments. best regards

• Using local configs in a Heroku deployment environment

  - by ambertch

  I'm trying to migrate my app to Heroku - I have a config file that varies with development/staging/production environments as it contains uniquely assigned keys (from Facebook, S3, etc.), so I keep it out of the repository and keep the configs local. As such I'm trying to find a solution for Heroku to have that config file since Heroku deploys from the repository. I noticed Heroku deploys from the master branch - can it deploy from another branch? Because then I could commit the Heroku configs there, and have it not overwrite the other environments' configs every time it pulls. Thanks!

• jQuery.Form wont submit

  - by kim

  Im´trying to submit a form without refreshing the page, but I´m having a problem. When I click submit the page refreshes and anothing gets posted. Here is the code, what am I doing wrong? (I´m a newbie) jQuery 1.4.2 and the jQuery Form Plugin 2.43 is present. tnx $(document).ready(function() { var options = { target: '#output2', url: https://graph.facebook.com/<%=fbUid%>/feed, type: post, clearForm: true // clear all form fields after successful submit //dataType: null // 'xml', 'script', or 'json' (expected server response type) //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: //timeout: 3000 }; // bind to the form's submit event $('#fbPostStatus').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); });

• Why is this global variable not being changed???

  - by user398314

  Why does this turn up null instead of being set to the data returned from the ajax call? It must be something simple i am overlooking. var message; $(document).ready(function(){ fbFetchMessage(); alert(message); }); function fbFetchMessage(){ var url = "http://graph.facebook.com/companyname/feed?callback=?"; $.getJSON(url,function(json){ message = json.data[0].message; }); }

• Creating a "Universities Attended" Profile field/block (Drupal)

  - by Frank0051

  Interesting question for everyone. So I have am thinking of adding a "university attended" field to the profile page of members in Drupal. I guess I am trying to figure out the best way to go about it. I was originally thinking of a text field, but than I thought you could get multiple instances of of university names, making it hard to sort people by school (ie. UF, University of Florida, Florida, U of F, etc). I then began to think about creating a drop down, but I wasn't quite sure where I could get a listing of all the schools. Perhaps I could find a database population that a site like LinkedIn or Facebook uses. Then I thought of what happens when someone has attended multiple schools, how would I account for that? So, I guess I wanted to pose the question of how would you go about adding a University(ies) attended field to profile pages if you had to design a site to do so?

• Can we change <input type="file"> style?

  - by learner.php

  I tried to change the HTML form, input type file. Here is my code: HTML, form id = form <input class="upload_file" type="file" id="file" name="file" /> .CSS I tried both: .upload_button{ background: url('../images/upload_btn_bg.png') no-repeat; width: 200px; height: 40px; } #form input[type=file]{ background: url('../images/upload_btn_bg.png') no-repeat; width: 200px; height: 40px; } None of both of those methods works. I did see from some website, like facebook, youtube, google or twitter, they have different style. Wonder how they do it.

• How much more productive is an extra monitor?

  - by Sir Graystar

  I am mulling over whether to buy a new monitor, to go along side my current setup of two 24 (ish) inch monitors. What I want to know is whether this is worth the money (probably around £200)? I think most of us will agree that two monitors is much more productive than one when programming and developing (Jeff Atwood has said this many times on his blog, and I imagine that most of you are fans of his), but is three much more productive than two? What I'm worried about is that I will have so much space that one monitor will be used for things that are not related to the task (music, facebook etc.) and it will actually make me less productive.

• jQuery sanitizing comments and linkifying URLs

  - by iWasRobbed

  In terms of jQuery (or Javascript), what happens behind the scenes when a person posts a comment on Facebook, Twitter, or a blog? For instance, do they sanitize the text first, and then pattern match URL's into an actual link? Are there other items of concern that the client-side should check in addition to doing some checks on the backend? I have found a few regex's for turning URL's into links, but I'm not sure if there are better solutions. I'm trying to wrap my head around the problem, but I'm having a difficult time knowing where to start. Any guidance you can provide is greatly appreciated!

• Preventing a security breach

  - by Wiz

  I am creating a website where you "post", and the form content is saved in a MySql database, and upon loading the page, is retrieved, similar to facebook. I construct all the posts and insert raw html into a template. The thing is, as I was testing, I noticed that I could write javascript or other HTML into the form and submit it, and upon reloading, the html or JS would treated as source code, not a post. I figured that some simple encoding would do the trick, but using is not working. Is there an efficient way to prevent this type of security hole?

• How do I make a URL text a link?

  - by jpjp

  Say on Facebook or Twitter, when I type "www.google.com" and submit it, it becomes a link. How do I code this in PHP? Do I use regular expressions to get where the www starts and the .com ends? Is this how they do it? <?PHP //some regular expression to get www and .com part $link="<a href='$url'>$url</a>"; echo $link; ?> How do I write a regular expression to get the "www" and ".com" part? And for twitter's @obama, obama would become a link to obama's site. What regular expression do they use to get the text after the @ and before the space?

• The importance of knowing c++ for web application development

  - by neitony

  I'm a php developer and I want to broaden my knowledge base by learning a higher language (java, c#, c++). My specialty is in building web applications (ria etc). I'm trying to think of the appropriate path to take (hedging my bets so to speak) in terms of which language I should be focusing on. I love open source technology but at the same time C# seems to be getting a lot of notoriety. Despite the newer technologies available there still remains c++ which is the staple for many popular vendors including google and facebook (hip hop) in building scalable and robust cross platform apps. Can anyone offer suggestions as to how I should be looking at this. Should I go Java, C# or C++). They all take time to master and I just want to choose a specialty. Thanks

• Robust way to display an image with one fixed dimension

  - by DomingoSL

  Lets say that we have an image uploaded by the user, the upload script limits the mb but not the image size (so could be any proportion, 600X200,200X350, and so...). Im already showing this image in one part on my site using the twitter bootstrap image handler written on css, thats good for a profile picture, the problem is that now I want that image to be a cover (like facebook/twitter cover image), my site is responsive so the width of the cover is 900px or 100% if the screen resolution is less than 900px wide. The height is always fixed to 200px. So I know there is a way to control the correct image display using CSS (maybe with jquery too) but Im not a front-end dev, Im a php dev and I dont want to use server side scripts for doing this. So im looking for suggestions or pieces of codes (css, javascript) to start with, I belive that it have to be an already made solution for this, but I dont find any on google. Thanks for any advice!

• building an XML service parsing library

  - by DanInDC

  This is more of a design question I suppose. My company offers a web service to our client that spits data out in a custom xml format. I'd like to build a java library we can offer so our customers can just feed it the url and we will turn it into a set of POJOs built from the response. I can obviously just create a library that will do some simple xml parsing and building of the POJOs but I'm looking to build something a bit more robust. My brain is pulling me in a million directions, wondering if anyone has some pointers or some code to poke at. Was thinking about adding an Abdera extension, but it's not really a syndication format that fits the Abdera model. And most of the popular service libraries (twitter, facebook) all rely on standards format parsers, of which our format isn't.

• Knowledge mining using Hadoop.

  - by Anurag

  Hello there, I want to do a project Hadoop and map reduce and present it as my graduation project. To this, I've given some thought,searched over the internet and came up with the idea of implementing some basic knowledge mining algorithms say on a social websites like Facebook or may stckoverflow, Quora etc and draw some statistical graphs, comparisons frequency distributions and other sort of important values.For searching purpose would it be wise to use Apache Solr ? I want know If such thing is feasible using the above mentioned tools, if so how should I build up on this little idea? Where can I learn about knowledge mining algorithms which are easy to implement using java and map reduce techniques? In case this is a wrong idea please suggest what else can otherwise be done on using Hadoop and other related sub-projects? Thank you

• How to setup a http(s) proxy with record/replay functionality?

  - by superb

  The use case is: I want to do some android app performance tests and I want to fix the data when app got from web. The solution I come up with is to setup a local http proxy, which can first record all http traffic, and later replay then app is running perf tests. I found http://mitmproxy.org/, which has exactly the features I want. but seems with the default settings it cannot be used as a https proxy. I tried using it as proxy and login to facebook but doesn't work. I am not familiar with the https protocol and how cert things work. Any one can provide some help? Thanks a lot.

• Javascript is freezing the browser when running this code

  - by user1420493

  I am trying to get the value of a text input and check if there is any links in it and then take those links and make them into tags. But when I run this code, something is going wrong and it completely freezes the page. Basically, I want it to check for "http://" and if that exists, to keep on adding to the substr length until the end of the string/link. Is there a better way to do this? // the id "post" could possibly say: "Hey, check this out! http://facebook.com" // I'd like it to just get that link and that's all I need help with, just to get the // value of that entire string/link. var x = document.getElementById("post"); var m = x.value.indexOf("http://"); var a = 0; var q = m; if (m != -1) { while (x.value.substr(q, 1) != " ") { var h = x.value.substr(m, a); q++; } }

• Can I do this in only one query ?

  - by Paté

  Merry christmas everyone, I Know my way around SQL but I'm having a hard time figuring this one out. First here are my tables (examples) User id name friend from //userid to //userid If user 1 is friend with user 10 then you a row with 1,10. User 1 cannot be friend with user 10 if user 10 is not friend with user 1 so you have 1,10 10,1 It may look weird but I need those two rows per relations. Now I'm trying to make a query to select the users that have the most mutual friend with a given user. For example User 1 is friend with user 10,9 and 7 and user 8 is friend with 10,9 and 7 too ,I want to suggest user 1 to invite him (like facebook). I want to get like the 10 first people with the most mutual friend. The output would be like User,NumOfMutualFriends I dont know if that can be done in a single query ? Thanks in advance for any help.
