  • Windows Phone 7, download xml over ssl with authentication

    - by Snake
    Hi, I'm trying to download a file from my provider. The url is protected with basic username and password, and everything is sent over ssl. So I try to do this: WebClient proxy = new WebClient(); proxy.DownloadStringCompleted += (o, dscea) => System.Diagnostics.Debugger.Break(); proxy.Credentials = new NetworkCredential("username", "password"); proxy.DownloadStringAsync(new Uri("https://..../.../data.xml")); As you can see I try to validate. The data IS correct, and the code works when I try to download something from twitter. What am I forgetting to connect to this xml file?

  • Why might someone say R is *NOT* a programming language? [closed]

    - by Tal Galili
    I came by the following comment today on twitter "R is not a programming language, it's a statistics package with the GUI missing." And I am wondering - Why not? What is "missing" in R to make it a "programming language" ? Update: For the protocol, I am a big fan of R, use it daily, and support it's existence. I now changed the name of this thread from "Why is R NOT a programming language?" to "Why might someone say R is NOT a programming language?" Which better reflects my motivation for this thread (which is, to know if R has any programmatical disadvantages that I might have not heard about).

  • rake db:migrate fails when trying to do inserts

    - by anthony
    I'm trying to get a database populate so I can begin working on a project. THis project is already built and I'm being brought in to helpwith front-end work. Problem is I can't get rake db:migrate to do any inserts. Every time I run rake db:migrate I get this: ... == 20081220084043 CreateTimeDimension: migrating ============================== -- create_table(:time_dimension) - 0.0870s INSERT time_dimension(time_key, year, month, day, day_of_week, weekend, quarter) VALUES(20080101, 2008, 1, 1, 'Tuesday', false, 1) rake aborted!

  • How to get current controller for a URL in Rails?

    - by valk
    I'm using this code to highlight currently active menu tab with Twitter Bootstrap: def nav_link_to(link_text, link_path, options = nil) class_name = current_page?(link_path) ? 'active' : '' content_tag(:li, :class => class_name) do link_to link_text, link_path, options end end This of course makes the link active, only if the given link IS the current page. How can I change this function, such that it would return 'active' for any links below current controller? In other words, for all actions for Posts controller, the links would be active? Thanks.

  • Pass object or id

    - by Charles
    This is just a question about best practices. Imagine you have a method that takes one parameter. This parameter is the id of an object. Ideally, I would like to be able to pass either the object's id directly, or just the object itself. What is the most elegant way to do this? I came up with the following: def method_name object object_id = object.to_param.to_i ### do whatever needs to be done with that object_id end So, if the parameter already is an id, it just pretty much stays the same; if it's an object, it gets its id. This works, but I feel like this could be better. Also, to_param returns a string, which could in some cases return a "real" string (i.e. "string" instead of "2"), hence returning 0 upon calling to_i on it. This could happen, for example, when using the friendly id gem for classes. Active record offers the same functionality. It doesn't matter if you say: Table.where(user_id: User.first.id) # pass in id or Table.where(user_id: User.first) # pass in object and infer id How do they do it? What is the best approach to achieve this effect?

  • convert std object class to comma seperated string

    - by Kwaasi Djin
    I have an std class object from twitter and i would like to take the ids array values and put them in a php variable $ids where $ids = (15761916,30144785,382747195,19399719). I imagine using a for loop and using phps implode but i'm not sure how to go about it. stdClass Object ( [ids] => Array ( [0] => 15761916 [1] => 30144785 [2] => 382747195 [3] => 19399719 ) [next_cursor] => 0 [next_cursor_str] => 0 [previous_cursor] => 0 [previous_cursor_str] => 0 )

    - by Cy

Can you guide me on how to perform this task? -(void) setTextTwitter:(NSString *)text WithDate:(NSString*)date { [text retain]; [textTwitter release], textTwitter = nil; textTwitter = text; [date retain]; [dateTwitter release], dateTwitter = nil; dateTwitter = date; [self setNeedsDisplay]; }

  • 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!

  • UITextView or UIWebView with normal words looking like links

    - by diwup
    Hey guys, I was looking at the Twitter for iPhone app and was puzzled. First of all, there are normal words looking like links inside. Second, when I touch those link-like words, the text view (or maybe web view) jumps to the corresponding part below (yes, it doesn't open Safari, it just jumps to the text within that text/web view) Now I want to implement the same effects. I should base my implementation on what? UITextView or UIWebView? How to make normal words look like links? How to make those smooth jumps within such a text/web views? Thanks in advance.

  • Two Column Theme, Help, to make both columns seperately Scrollable.

    - by Michael macDonald
    Hey, I am not sure what to do on this one, I'm not a programmer, but trying to learn CSS as this is how the theme I am using was coded in. I've gotten quite far on my own, but this one stumps me Its two column Theme... As far as I have been able to get, I can use the following: #left { width: 235px; padding: 10px; margin-left: 20px; position: fixed; line-height: 15px; If I change the position to Absolute, The whole page scrolls, If I leave it at Fixed, and add lets say, a Twitter feed, or other type of text that takes me past its reading where you would normally scroll, Its just cut off, cannot get to it, hightlight or scroll.. I've also toyed with the idea, of changing the theme to a 3 column theme, but Again, not a programmer, and i'd be really confused. anyhelp would be great... My Website is at 99lessoxygen.tumblr.com, code was found from http://nigredotheme.tumblr.com

  • How do I use Haml in a view in my new plugin?

    - by Eric
    I'm creating a new plugin for a jruby on rails application that will eventually be turned into a gem. Inside my plugin I have controllers, helpers and views. For my views I'd like to use Haml. The problem is that I can't seem to get it to recognize that they are haml templates. Is it even possible to do this? Is there a way for a plugin to have Haml as a dependency for its view? And by that I mean, I intend for the plugin that I'm creating to have a view created by the plugin, that can be used by the application developer. for example: vendor/ plugins/ my_plugin/ lib/ app/ views/ my_plugin_demo/ index.haml.html controllers/ my_plugin_demo_controller.rb helpers/ In my plugin's init.rb, I tried: require 'my_plugin' require 'haml' #doesn't seem to make a difference :( but that didn't seem to make any difference. Has anybody had any experience with this? I can't seem to find any documentation on how to make this work. Are plugin views restricted to .erb templates?

  • Do you prefer to code on a Laptop or a Desktop, or both ?

    - by CAD bloke
    What is your primary development machine - a Desktop or a laptop? Why? Do you use both - if so, do you use source control to keep them synched? This might seem like a dumb question but I'm on the steep part of the learning curve & I'd be interested in your insights. [edit] - Using a laptop assumes hanging an Imax-sized screen off it when it is docked. Using a desktop assumes 2x Imax screens. [edit] - This is faster than Twitter! IDE is VS2008 - laptop is 17 (or 15) inch, 1920x1200

  • 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.

  • Bizarre static_cast trick?

    - by Rob
    While perusing the Qt source code I came across this gem: template <class T> inline T qgraphicsitem_cast(const QGraphicsItem *item) { return int(static_cast<T>(0)->Type) == int(QGraphicsItem::Type) || (item && int(static_cast<T>(0)->Type) == item->type()) ? static_cast<T>(item) : 0; } Notice the static_cast<T>(0)->Type? I've been using C++ for many years but have never seen 0 being used in a static_cast before. What is this code doing and is it safe? Background: If you derive from QGraphicsItem you are meant to declare an unique enum value called Type that and implement a virtual function called type that returns it, e.g.: class Item : public QGraphicsItem { public: enum { Type = MAGIC_NUMBER }; int type() const { return Type; } ... }; You can then do this: QGraphicsItem* item = new Item; ... Item* derivedItem = qgraphicsitem_cast<Item*>(item); This will probably help explain what that static_cast is trying to do.

  • Weird Rails database errors

    - by Jason Swett
    I've had some trouble getting my Rails app to connect to PostgreSQL so I decided to just say screw it and use SQLite for now. (I'm using the tutorial here: http://guides.rubyonrails.org/getting_started.html) I started a BRAND NEW, fresh Rails app from this tutorial. When I visit my app in the browser after deleting public/index.html, I get this the first time: Please install the pg adapter: `gem install activerecord-pg-adapter` (no such file to load -- active_record/connection_adapters/pg_adapter) That's odd to me because I'm not mentioning PostgreSQL anywhere. Here's my databases.yml: # SQLite version 3.x # gem install sqlite3-ruby (not necessary on OS X Leopard) development: adapter: sqlite3 database: db/development.sqlite3 pool: 5 timeout: 5000 # Warning: The database defined as "test" will be erased and # re-generated from your development database when you run "rake". # Do not set this db to the same as development or production. test: adapter: sqlite3 database: db/test.sqlite3 pool: 5 timeout: 5000 production: adapter: sqlite3 database: db/production.sqlite3 pool: 5 timeout: 5000 To make things more confusing, I only get that "pg adapter" error on the first load. For every subsequent page request, I get this error: ActiveRecord::ConnectionNotEstablished So even though I removed all mention of PostgreSQL, I'm still getting errors. What could be going on?

  • 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.

  • How to give the appearance of a button with a <div>?

    - by user246114
    Hi, I'm looking at the buttons used on twitter's home page, specifically the big orange 'signup' button. I see it is defined like this: <p id="signup-btn"> <a id="signup_submit" href="/signup"> <span>Sign Up</span> </a> </p> are they just using css to give the orange button appearance (which may just be a jpg), and also using css to specify the roll-over appearance (another jpg), and finally a third state for mouse-click (another jpg) to give the impression of a real clickable button? If that's how it works, what should I look for to do the same thing? In my case I just want to make a button I guess, like: <div class='mybutton'>Hello!</div> .mybutton { bgcolor: red; bgcolor-mouseover: yellow; bgcolor-mousedown: green; } yeah something like that would be great, Thanks

  • getting active records to display as a plist

    - by phil swenson
    I'm trying to get a list of active record results to display as a plist for being consumed by the iphone. I'm using the plist gem v 3.0. My model is called Post. And I want Post.all (or any array or Posts) to display correctly as a Plist. I have it working fine for one Post instance: [http://pastie.org/580902][1] that is correct, what I would expect. To get that behavior I had to do this: class Post < ActiveRecord::Base def to_plist attributes.to_plist end end However, when I do a Post.all, I can't get it to display what I want. Here is what happens: http://pastie.org/580909 I get marshalling. I want output more like this: [http://pastie.org/580914][2] I suppose I could just iterate the result set and append the plist strings. But seems ugly, I'm sure there is a more elegant way to do this. I am rusty on Ruby right now, so the elegant way isn't obvious to me. Seems like I should be able to override ActiveRecord and make result-sets that pull back more than one record take the ActiveRecord::Base to_plist and make another to_plist implementation. In rails, this would go in environment.rb, right?

  • The best way to structure this database?

    - by James P
    At the moment I'm doing this: gems(id, name, colour, level, effects, source) id is the primary key and is not auto-increment. A typical row of data would look like this: id => 40153 name => Veiled Ametrine colour => Orange level => 80 effects => +12 sp, +10 hit source => Ametrine (Some of you gamers might see what I'm doing here :) ) But I realise this could be sorted a lot better. I have studied database relationships and secondary keys in my A-Level computing class but never got as far as to set one up properly. I just need help with how this database should be organised, like what tables should have what data with what secondary and foreign keys? I was thinking maybe 3 tables: gem, effects, source. Which then have relationships to each other? Can anyone shed some light on this? Is a complex way like I'm proposing really the way to go or should I just carry on with what I'm doing? Cheers.

  • Mercurial and particular files branching

    - by zerkms
    The context: i have a project, that contains configs/ directory, which contains (surprise-surprise!) a set of config files: database.php, facebook.php, twitter.php, cache.php, etc What I did in svn: I have created branches per specific file and made changes there (changed database connections, facebook API keys, etc). So they were stored in my private branch. Now I'm trying to migrate to "modern" nowadays DSCM - Mercurial. And I cannot get any possibility of doing the same. Any ideas?

  • SO style alert header

    - by Zachary
    I apologize if this question is vague, but I want to build a drop down header, very similar to the one on StackOverflow that alerts you whenever you have earned a new badge, or on Twitter whenever a new tweet comes in. I've been looking around on the internet for a tutorial, but I'm having trouble googling exactly what I'm looking for. I assume there is a way to do this in jQuery, or there may be a jQuery plugin for it, but I haven't had any luck finding one. The idea would probably be to make an AJAX request every so many seconds, and if a new alert-worthy item is found, display it for the user. If someone could point me to a resource to learn how to build one, and/or an existing plugin, that would be great.
