  • Facebook login on headless browser

    - by dmni
    My Facebook app has a function of automating tasks on server side headless browser (like visiting app links). Now, I use the Facebook SDKs to log user in and access user's news stream to search for links and other information. Once the app has found all the links, it is supposed to pass this information in to the headless browser which will then proceed to visit in them for example. The problem is that these headless browser windows' are not logged in. I would like the headless browser to be temporary logged in as the user launching the tasks from the app. Is this possible?

  • google contacts api service account oauth2.0 sub user

    - by user3709507
    I am trying to use the Google Contacts API to connect to a user's contact information, on my Google apps domain. Generating an access_token using the gdata api's ContactsService clientlogin function while using the API key for my project works fine, but I would prefer to not store the user's credentials, and from the information I have found that method uses OAuth1.0 So, to use OAuth2.0 I have: Generated a Service Account in the developer's console for my project Granted access to the service account for the scope of https://www.google.com/m8/feeds/ in the Google apps domain admin panel Attempted to generate credentials using SignedJwtAssertionCredentials: credentials = SignedJwtAssertionCredentials( service_account_name=service_account_email, private_key=key_from_p12_file, scope='https://www.google.com/m8/feeds/', sub=user_email') The problem I am running into is that attempting to generate an access token using this method fails. It succeeds in generating the token when I remove the sub parameter, but then that token fails when I try to fetch the user's contacts. Does anyone know why this might be happening?

  • How do I alter the Epitwitter scripts to post to twitter from a web form?

    - by waterfallrain
    Hello, I am trying to update my twitter status with php and outh using the Epitwitter scripts. The following is the textarea of the web form I created to allow me to update twitter. <textarea name="updatestatus" cols="50" rows="4" id="updatestatus"> </textarea> Do I change this line in my confirm.php script from $status = 'Testing API'; To this $status=$_POST["updatestatus"]; I am wanting to know if I at least got that right so I can look at other possible problems with this form not being able to update twitter. As it stands now I am manually editing the status each time and it works that way perfectly but have not yet figured out how to get a webform to do this.

  • Oauth2 External Browser Request - App Launches, Credentials received, Browser Not Updated

    - by Michael Drozdowski
    I'm using an external browser request to authenticate myself with the SoundCloudAPI in OSX. My app launches, and has a button that opens an external browser window to authenticate against SoundCloud. When I click "connect" in the new window, I get a "External Protocol Request" that is consistent with my custom launch URI scheme. Clicking this loads the app, and it gets the correct credentials. The trouble is, the browser window never changes - it simply says that it's connecting forever. There is no "connection confirmed" alert coming from SoundCloud. I know I'm logged in because I can make the correct calls to the API to get things such as my username. Why isn't the browser confirming the connection or dismissing? The same thing happens if I load the authentication in an internal WebView in the app.

  • Using Google's Contacts API's, how can I get the user's name and gmail address?

    - by chris
    I know how to get the entire contacts list using Google Contacts API (I get a session token and use Google's Zend package for PHP). But how can I get the person's name and email address? Currently, the Contacts API just seems to give all of the contacts. I'm not sure how to distinguish which email and name out of that list corresponds to the user's account. Is there an easy way to get the user's full name and email address? Any help would be useful. Thanks!

  • Making a calendar tool with Google API. Should I use OAuth Service Account?

    - by Goluxas
    I'm creating a calendar tool for a client. He has his work calendars in a Google account, which I have access to. I'll be using the Google Calendar API for the tool, but I'm new to Google APIs and the OAuth stuff. I'll be using PHP. Do I need to use an OAuth2 Service Account, or should I make a regular OAuth2 Web Application Client ID from that Google account? In case this information is helpful, the tool I will be making will do this: 1) Allow my client to fill out a form which will create a new calendar and populate it with several events. 2) Send out an email to a mailing list twice a week listing changes that have been made to these calendars. I'll also be making a page that displays the iframes for each calendar, so his clients may see them even if they do not have a Google account.

  • Newbie, deciding Python or Erlang

    - by Joe
    Hi Guys, I'm a Administrator (unix, Linux and some windows apps such as Exchange) by experience and have never worked on any programming language besides C# and scripting on Bash and lately on powershell. I'm starting out as a service provider and using multiple network/server monitoring tools based on open source (nagios, opennms etc) in order to monitor them. At this moment, being inspired by a design that I came up with, to do more than what is available with the open source at this time, I would like to start programming and test some of these ideas. The requirement is that a server software that captures a stream of data and store them in a database(CouchDB or MongoDB preferably) and the client side (agent installed on a server) would be sending this stream of data on a schedule of every 10 minutes or so. For these two core ideas, I have been reading about Python and Erlang besides ruby. I do plan to use either Amazon or Rackspace where the server platform would run. This gives me the scalability needed when we have more customers with many servers. For that reason alone, I thought Erlang was a better fit(I could be totally wrong, new to this game) and I understand that Erlang has limited support in some ways compared to Ruby or Python. But also I'm totally new to the programming realm of things and any advise would be appreciated grately. Jo

  • Nested Routes and Parameters for Rails URLs (Best Practice)

    - by viatropos
    Hey there, I have a decent understanding of RESTful urls and all the theory behind not nesting urls, but I'm still not quite sure how this looks in an enterprise application, like something like Amazon, StackOverflow, or Google... Google has urls like this: http://code.google.com/apis/ajax/ http://code.google.com/apis/maps/documentation/staticmaps/ https://www.google.com/calendar/render?tab=mc Amazon like this: http://www.amazon.com/books-used-books-textbooks/b/ref=sa_menu_bo0?ie=UTF8&node=283155&pf_rd_p=328655101&pf_rd_s=left-nav-1&pf_rd_t=101&pf_rd_i=507846&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1PK4ZKN4YWJJ9B86ANC9 http://www.amazon.com/Ruby-Programming-Language-David-Flanagan/dp/0596516177/ref=sr_1_1?ie=UTF8&s=books&qid=1258755625&sr=1-1 And StackOverflow like this: http://stackoverflow.com/users/169992/viatropos http://stackoverflow.com/questions/tagged/html http://stackoverflow.com/questions/tagged?tagnames=html&sort=newest&pagesize=15 So my question is, what is best practice in terms of creating urls for systems like these? When do you start storing parameters in the url, when don't you? These big companies don't seem to be following the rules so hotly debated in the ruby community (that you should almost never nest URLs for example), so I'm wondering how you go about implementing your own urls in larger scale projects because it seems like the idea of not nesting urls breaks down at anything larger than a blog. Any tips?

  • Cannot login to Activeadmin after gem update

    After bundle update I cannot login to my Activeadmin, here is the log. Is it because the unpermitted params? do I need to config strong parameter to make admin login work?

  • RubyGems installation errors both when using 'sudo' and not using sudo

    - by Kenny Peng
    I have a machine that is running Ubuntu Hardy, which provides its own RubyGems package. Unfortunately that version of RubyGems (1.1.1) is too old to do anything useful with, so I decided to manually update RubyGems to the current version (1.3.6). That part went smoothly, and if I do gem -v, I get 1.3.6 which is expected. The problem is when I try to do: sudo gem install rack, it returns this error: ERROR: While executing gem ... (Errno::EACCES) Permission denied - /home/username/.gem Usually when I install gems as root, it knows to install it into /usr/lib/ruby/gems, so why is it checking my home directory at all? Another quirk is when I do gem install rack (not as root), it says: ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions into the /usr/lib/ruby/gems/1.8 directory. which is where I want it to go. I've already tried clearing source_caches, trying different versions of RubyGems (1.3.5), forcing installation into /usr/lib with -i to no avail. Any ideas on why RubyGems is so insistent on checking my /home directory when installing as root?

  • Rails apps blew up on mediatemple's (dv) server

    - by BandsOnABudget
    i managed to fix this issue but i wanted to document it here for any others whom might have similar problems. I'm running a mediatemple (dv) rage server. monit started sending me alerts that i was having resource limitations on the server. logged into plesk and the CPU was pinned at 99.9%. Rebooted the server, catastrophe avoided... Not quite - all my rails apps were not loading My Setup ruby 1.8.6 Rails 2.3.5 w/ passenger installed as an apache module. I noticed a defunct ruby process so i killed and rebooted the server but runby continued to come back as defunct. Started trolling thru the apache log and i saw errors irt updating rubygems. i updated to the latest but then continued to get gem errors. Basically, I had to go thru all my apps and update any gems manually, reboot apache, and all was restored. Not really sure the cause of the issue but wanted to note it for posterity. Anybody else in the community ever have similar issues???

  • Problems with Merb on Snow Leopard

  • SQL Server Trouble with Rails

    - by Earlz
    Ok, I've been trying to get this to work like all day now and I'm barely any further from when I started. I'm trying to get Ruby On Rails to connect to SQL Server. I've installed unixODBC and configured it and FreeTDS and installed just about every Ruby gem relating to ODBC that exists. [earlz@earlzarch myproject]$ tsql -S AVP1 -U sa -P pass locale is "en_US.UTF-8" locale charset is "UTF-8" 1> quit [earlz@earlzarch myproject]$ isql AVP1 sa pass [ISQL]ERROR: Could not SQLConnect [earlz@earlzarch myproject]$ rake db:version (in /home/earlz/myproject) rake aborted! IM002 (0) [unixODBC][Driver Manager]Data source name not found, and no default driver specified (See full trace by running task with --trace) so, as you can see, tsql works, but not isql. What is the difference in the two that breaks it? /etc/odbc.ini [AVP1] Description = ODBC connection via FreeTDS Driver = TDS Servername = my.server UID = sa PWD = pass port = 1232 Database = mydatabase /etc/odbcinst.ini [TDS] Description = v0.6 with protocol v7.0 Driver = /usr/lib/libtdsodbc.so Setup = /usr/lib/libtdsS.so CPTimeout = CPReuse = FileUsage = 1 (and yes, I've made sure that the .so files exist) the relevant part in freetds.conf [AVP1] host = my.server port = 1232 tds version = 8.0 and finally, my database.yml development: adapter: sqlserver mode: odbc dsn: AVP1 username: sa password: pass Can anyone please help me before I pull all my hair out? I am using a 64 bit Arch Linux that is completely up to date.

  • Is it possible to convert a 40-character SHA1 hash to a 20-character SHA1 hash?

    - by ewitch
    My problem is a bit hairy, and I may be asking the wrong questions, so please bear with me... I have a legacy MySQL database which stores the user passwords & salts for a membership system. Both of these values have been hashed using the Ruby framework - roughly like this: hashedsalt = Digest::SHA1.hexdigest("--#{Time.now.to_s}--#{login}--") hashedpassword = Digest::SHA1.hexdigest("#{hashedsalt}:#{password}") So both values are stored as 40-character strings (varchar(40)) in MySQL. Now I need to import all of these users into the ASP.NET membership framework for a new web site, which uses a SQL Server database. It is my understanding that the the way I have ASP.NET membership configured, the user passwords and salts are also stored in the membership database (in table aspnet_Membership) as SHA1 hashes, which are then Base64 encoded (see here for details) and stored as nvarchar(128) data. But from the length of the Base64 encoded strings that are stored (28 characters) it seems that the SHA1 hashes that ASP.NET membership generates are only 20 characters long, rather than 40. From some other reading I have been doing I am thinking this has to do with the number of bits per character/character set/encoding or something related. So is there some way to convert the 40-character SHA1 hashes to 20-character hashes which I can then transfer to the new ASP.NET membership data table? I'm pretty familiar with ASP.NET membership by now but I feel like I'm just missing this one piece. However, it may also be known that SHA1 in Ruby and SHA1 in .NET are incompatible, so I'm fighting a losing battle... Thanks in advance for any insight.

  • deploy a sinatra app with passenger gives only 404, page not founds. Yet a simple rack app works.

    - by berkes
    I have correctly (or prbably not) installed passenger on apache 2. Rack works, but sinatra keeps giving 404's. Here is what works: config.ru: #app = proc do |env| return [200, { "Content-Type" => "text/html" }, "hello <b>world</b>"] end run app Here is what works too: Running the app.rb (see below) with ruby app.rb and then looking at localhost:4567/about and / restarting the app, gives me a correct hello world. w00t. But then there is the sinatra entering the building: config.ru require 'rubygems' require 'sinatra' root_dir = File.dirname(__FILE__) set :environment, ENV['RACK_ENV'].to_sym set :root, root_dir set :app_file, File.join(root_dir, 'app.rb') disable :run run Sinatra::Application and an app.rb require 'rubygems' require 'sinatra' get '/' do "Hallo wereld!" end get '/about' do "Hello world, it's #{Time.now} at the server!" end This keeps giving 404s. /var/logs/apache2/error.log lists these correctly as "404" with something that worries me: 83.XXXXXXXXX - - [30/May/2010 16:06:52] "GET /about " 404 18 0.0007 83.XXXXXXXXX - - [30/May/2010 16:06:56] "GET / " 404 18 0.0007 The thing that worried me, is the space after the / and the /about. Would apache or sinatra go looking for /[space], like /%20? If anyone knows what this problem relates to, maybe a known bug (that I could not find) or a known gotcha? Maybe I am just being stupid and getting "it all wrong?" Otherwise any hints on where to get, read or log more developers data on a running rack, sinatra or passenger app would be helpfull too: to see what sinatra is looking for, for example. Some other information: Running ubuntu 9.04, apache2-mm-prefork (deb), mod_php5, ruby 1.8.7, passenger 2.2.11, sinatra 1.0

  • Rails 2.3.2 trying to render ERB instead of HAML

    Rails is suddenly trying to render ERB instead of Haml and I can't figure out why. I've created new rails projects, reinstalled Haml, and reinstalled Rails. Here's exactly the steps I take when making my application (Rails 2.3.2): rails> rails test rails> cd test rails\test> haml --rails . rails\test> ruby script\generate model user email:string password:string rails\test> ruby script\generate controller users index rails\test> rake db:migrate Here's what the UsersController looks like: class UsersController < ApplicationController def index @users = User.all end end My routes: ActionController::Routing::Routes.draw do |map| map.resources :users end I now create views\users\index.html.haml: %table %th(style="text-align: left;") %h1 Users - for user in @users %tr %td= user.email %td= user.password Annnd run the server... I navigate to localhost:3000\users and I get this error message: Template is missing Missing template users/index.erb in view path app/views For some reason Rails is trying to find and render .erb files instead of .haml files. vendor\plugins\haml\init.rb exists, untouched. I've reinstalled Haml (Pretty Penny) multiple times and still get the same results. I've also tried adding config.gem 'haml' to my environment.rb but this also doesn't work. I can't figure out why suddenly rails will not render haml for me.

  • XMPP4R Callbacks dont seem to work

    Im using xmpp4r and trying to get the hang of a basic chat feature that I wish to implement later in my Rails app. My fundamentals on Ruby Threads is still a bit shaky so I would appreciate any help on this. Though I register the callback i dont get a response from my gmail account. I am able to send a message but my ruby program terminates. In order to prevent it from terminating I tried to stop on of the threads in the program but I cant seem to get it working. require 'rubygems' require "xmpp4r/client" require "xmpp4r/roster" include Jabber def connect client = Client.new(JID::new("[email protected]")) client.connect client.auth("test") client.send(Presence.new.set_type(:available)) client end def create_message(message, to_email) msg = Jabber::Message::new(to_email, message) msg.type = :chat msg end def subscribe(email_id) pres = Presence.new.set_type(:subscribe).set_to(email_id) pres end client = connect roster = Roster::Helper.new(client) roster.add_subscription_request_callback do |item,pres| roster.accept_subscription(pres.from) end def create_callback(client) $t4= Thread.new do client.add_message_callback do |m| puts m.body puts "................................Callback working" end end end puts "Client has connected" msg = create_message("Welcome to the winter of my discontent", "[email protected]") client.send(msg) create_callback(client) def check(client) $t3 = Thread.new do loop do puts "t3 still running........."

  • what is the point of heterogenous arrays?

    - by aharon
    I know that more-dynamic-than-Java languages, like Python and Ruby, often allow you to place objects of mixed types in arrays, like so: ["hello", 120, ["world"]] What I don't understand is why you would ever use a feature like this. If I want to store heterogenous data in Java, I'll usually create an object for it. For example, say a User has int ID and String name. While I see that in Python/Ruby/PHP you could do something like this: [["John Smith", 000], ["Smith John", 001], ...] this seems a bit less safe/OO than creating a class User with attributes ID and name and then having your array: [<User: name="John Smith", id=000>, <User: name="Smith John", id=001>, ...] where those <User ...> things represent User objects. Is there reason to use the former over the latter in languages that support it? Or is there some bigger reason to use heterogenous arrays? N.B. I am not talking about arrays that include different objects that all implement the same interface or inherit from the same parent, e.g.: class Square extends Shape class Triangle extends Shape [new Square(), new Triangle()] because that is, to the programmer at least, still a homogenous array as you'll be doing the same thing with each shape (e.g., calling the draw() method), only the methods commonly defined between the two.

  • Which apache worker to use with passenger and how?

    - by Millisami
    I've this config in my apache2.conf <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> # worker MPM # StartServers: initial number of server processes to start # MaxClients: maximum number of simultaneous client connections # MinSpareThreads: minimum number of worker threads which are kept spare # MaxSpareThreads: maximum number of worker threads which are kept spare # ThreadsPerChild: constant number of worker threads in each server process # MaxRequestsPerChild: maximum number of requests a server process serves <IfModule mpm_worker_module> StartServers 2 MaxClients 15 MinSpareThreads 4 MaxSpareThreads 5 ThreadsPerChild 15 MaxRequestsPerChild 50000 </IfModule> Now I'm confused here. Which module gets loaded on which conditions? The phusion guys have suggested to use the worker module. Since both are present in apache conf file, do I have to comment the mpm_prefork_module or leave it as it is? Following is my passenger conf file for apache: LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/ext/apache2/mod_passenger.so PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4 PassengerRuby /usr/bin/ruby1.8 PassengerMaxPoolSize 3 PassengerPoolIdleTime 999999 RailsFrameworkSpawnerIdleTime 0 RailsAppSpawnerIdleTime 0 I'm running just a single Rails 2.3.2 app on 256MB slice at slicehost. I'm not quite satisfied with the performance yet. Are the settings above are any good??
