  • Twitter @Anywhere oauth_bridge_code

    - by AngelCabo
    I'm having trouble with Twitter's implementation of an oauth_bridge_code for the @anywhere api. I've seen a few walkthrough's on how to use this functionality but I can't seem to get the request to work for me. I'm using Ruby on Rails with the oauth gem. My code is as follows: def callback consumer = OAuth::Consumer.new(APP_CONFIG['twitter_key'], APP_CONFIG['twitter_secret'], :site => "http://api.twitter.com", :request_token_path => "/oauth/request_token", :authorize_path => "/oauth/authorize", :access_token_path => "/oauth/access_token", :http_method => :post) request = OAuth::AccessToken.new consumer json = request.post("https://api.twitter.com/oauth/access_token?oauth_bridge_code=#{params[:oauth_bridge_code]}") end I keep getting 401 unauthorized responses from the signed post request even though this is supposed to be working according to this walkthrough: http://blog.abrah.am/2010/09/using-twitter-anywhere-bridge-codes.html and a presentation from Matt Harris on slideshare. Any ideas on what I'm doing wrong (besides possibly trying to hit functionality that may not be in place)? Greatly appreciated!

  • Websphere Java application startup

    - by Tom Barnett
    I have two Java applications running on a Websphere application server. The first application is COTS software (Plateau) I will call App1 and includes an API which can be used in custom applications to interact with App1. This app takes a couple minutes to start in Websphere. The second application is custom software I will call App2 and is deployed as a web service which utilizes the App1 API to interact with App1; so it is dependent on App1. This app takes just seconds to start in Websphere. I run into a problem in certain App1 functionality when we bounce Websphere and the App2 web service is called by a client before the App1 application has fully started. Is there a way I can delay App2 from starting until App1 is fully started in Websphere? Is there a way to design App2 to programmatically check that App1 is available before it attempts to use the API?

  • P/Invoke or C++/CLI for wrapping a C library

    - by Ian G
    Have a moderate size (40-odd function) C API that needs to be called from a C# project. The functions logically break up to form a few classes that will be API presented to the rest of the project. Are there any objective reasons to prefer P/Invoke or C++/CLI for the interoperability underneath that API, in terms of robustness, maintainability, deployment, ...? The issues I could think of that might be, but aren't problematic are: C++/CLI will require an separate assembly, the P/Invoke classes can be in the main assembly. (We've already got multiple assemblies and there'll be the C dlls anyway so not a major issue). Performance doesn't seem differ noticeable between the two methods. Issues that I'm not sure about are: My feeling is C++/CLI will be easier to debug if there's inter-op problem, is this true? Language familiarity enough people know C# and C++ but knowledge of details of C++/CLI are rarer here. Anything else?

  • Where is BuildConfig.DEBUG?

    - by Ollie C
    My project doesn't seem to be aware of this new constant that's apparently auto-generated in Android Tools r17 builds: "Added a feature that allows you to run some code only in debug mode. Builds now generate a class called BuildConfig containing a DEBUG constant that is automatically set according to your build type. You can check the (BuildConfig.DEBUG) constant in your code to run debug-only functions such as outputting debug logs." I've confirmed that this class is not being auto-generated anywhere in my project by the new tools. I deleted all project outputs (including all gen folders) and rebuilt, and only R.java classes are being generated. Why are the tools not generating the BuildConfig class? It may be relevant that I'm using IntelliJ.

  • What is the difference between the add and offer methods in a queue?

    - by Finbarr
    Take the PriorityQueue for example http://java.sun.com/j2se/1.5.0/docs/api/java/util/PriorityQueue.html#offer(E) According to the Collection API entry http://java.sun.com/j2se/1.5.0/docs/api/java/util/Collection.html the add method will often seek to ensure that an element exists within the Collection rather than adding duplicates. So my question is, what is the difference between the add and offer methods? Is it that the Offer method will add duplicates regardless? (I doubt that it is because if a Collection should only have distinct elements this would circumvent that).

  • Google App Engine Application Error 5

  • Java document parsing over internet using POST

    - by Travis
    I've looked all around and decided to make my own library for accessing the EVE API. Requests are sent to a server address such as /account/Characters.xml.aspx. Characters.xml.aspx requires two item be submitted in POST and then it returns an XML file. So far I have this but it does not work, probably becuase I am using GET instead of POST: //Get the API data DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = factory.newDocumentBuilder(); String url = "http://api.eveonline.com/account/Characters.xml.aspx?userID="+ userID+"?apiKey="+key; Document doc = builder.parse(url); How would I go about being able to parst an XML file that is generated by submitting variables in POST?

  • How to implement python to find value between xml tags?

    - by Harshit Sharma
    I am using google site to retrieve weather information , I want to find values between XML tags. Following code give me weather condition of a city , but I am unable to obtain other parameters such as temperature and if possible explain working of split function implied in the code: import urllib def getWeather(city): #create google weather api url url = "http://www.google.com/ig/api?weather=" + urllib.quote(city) try: # open google weather api url f = urllib.urlopen(url) except: # if there was an error opening the url, return return "Error opening url" # read contents to a string s = f.read() # extract weather condition data from xml string weather = s.split("<current_conditions><condition data=\"")[-1].split("\"")[0] # if there was an error getting the condition, the city is invalid if weather == "<?xml version=": return "Invalid city" #return the weather condition return weather def main(): while True: city = raw_input("Give me a city: ") weather = getWeather(city) print(weather) if __name__ == "__main__": main() Thank You

  • Google JavaScript CAPTCHA handling

    - by Sam
    I am using Google API's to provide maps on a web page, however, Google frequently prompts for a CAPTCHA (I only know this from going into Firebug, users just get a JavaScript error) for requests for its javascript API's (e.g. http://maps.google.co.uk/maps?file=api&v=2&key=xxxx). However, this prevents visitors from our network (a very large (UK wide) WAN) using Google Maps etc from using these sites with it on. This is likely due to the fact the IP is shared by many people, so Google sees it as spam. I don't see any way of contacting Google about this, so was wondering if there is any way of intercepting these failing JavaScript requests since they return a 403 status code? Perhaps by opening a new window, although that would not be user friendly (they will see the JavaScript after the CAPTCHA, so would be a cause of confusion and would need to refresh the page in question).

  • platform independent and open source

    - by Lukas Schmelzeisen
    Hey, OK i want to start writing platform independent and open source code (mostly C++). What do i have to consider when doing so? Stop using IDEs and better use makefiles from now on? What do all the "professional" open source coders do (like the guys behind GNU) and what tools do they use? I'm special interested into developing shared libraries. How do you get the cross platform (so working as ".so" on Linux and as ".dll" on Windows)? I'm working on Windows so I'm not that much into all the Linux tools and words, are there good tools to get the same result on Windows as on ?Linux Thanks

  • Passing arguments to anonymous inner classes

    - by synic
    I'm trying to make an API library for our web services, and I'm wondering if it's possible to do something like this: abstract class UserRequest(val userId: Int) { def success(message: String) def error(error: ApiError) } api.invokeRequest(new UserRequest(121) { override def success(message: String) = { // handle success } override def error(error: ApiError) = { // handle the error } } I'm talking about passing parameters to the anonymous inner class, and also overriding the two methods. I'm extremely new to Scala, and I realize my syntax might be completely wrong. I'm just trying to come up with a good design for this library before I start coding it. I'm willing to take suggestions for this, if I'm doing it the completely wrong way, or if there's a better way. The idea is that the API will take some sort of request object, use it to make a request in a thread via http, and when the response has been made, somehow signal back to the caller if the request was a success or an error. The request/error functions have to be executed on the main thread.

  • Websites' color scheme generators - what to do with them in real life?

    - by Marco Demaio
    On the web there are plenty of color scheme/palette generator tools and color palettes galleries. All of these tools/gelleries show many 3 to 5 colors palette as final result. Some of these tools: http://kuler.adobe.com, http://www.colorexplorer.com I know my question might sound ridicolous to someone who is involved in web dedign, but I don't understand what to do with these color palette. I mean, if I have to create a website, how am I supposed to apply this color palette to the website. Which color goes as foreground text, which one as background, which one for the links, which one for the page titles and so on? What are these color palette generators useful for then?! Thanks!

  • Developing a jQuery plugin that returns a given object, instead of jQuery object itself!

    - by mehdi5275
    Hi, Consider the following base code: (function($) { $.fn.myPlugin = function(settings) { return this.each(function() { //whatever }); }; }); The plugin returns a jQuery object. The question is how am I supposed to write a plugin that returns a custom object so that I can do something like this: var api = $('div.myelement').myPlugin(); api.onMyEventName(function(e, whateverParam) { //whatever }); It'd be highly appreciated if you could write some lines of code that describes me how to do that, how to call the onMyEventName function on a custom api object... Thanks.

  • How do I change the JAVA_HOME for ant?

    - by Eugene M
    I'm doing java work on a class server where I don't have root. Whenever I try to compile using ant, it points to the wrong directory (/usr/tomcat instead of /usr/tomcat/jre ). One of the things we were told to do when setting up our user accounts was to add export JAVA_HOME=/usr/tomcat/jre to the .bashrc file. I don't know if that was supposed to take care of the problem but it doesn't seem to. So, how can I change the JAVA_HOME property for ant but only for when I run ant? EDIT: echo $JAVA_HOME points to /usr/tomcat/jre echo $JAVA_HOME\bin points to /usr/tomcat/jrebin The problem is when I normally run ant I get this error: Unable to locate tools.jar. Expected to find it in /usr/tomcat/lib/tools.jar Buildfile: build.xml compile: [javac] Compiling 1 source file to /home/ejm244/build/classes BUILD FAILED /home/ejm244/build.xml:9: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK Total time: 0 seconds

  • Differentiate VMware network adapter from physical network adapters

    - by Venkat
    I have to differentiate between the real addresses and the VM addresses using any Windows API. I'm using Getadaptersaddresses API to populate a list of ipaddresses for the local machine. I need to extract only the "real" addresses apart from the addresses associated with the VMware network adapter and other addresses(auto-configuration and tunnel adapter addresses) I've not been able to find any API or any flag to differentiate this. Is there any way this can be done? PS:The IfType flag in the IP_ADAPTER_ADDRESSES structure returned by Getadaptersaddresses doesn't help me differentiate between VMware addresses and the real addresses

  • Visual Studio 2008, MSBuild: "replacement" projects

    - by liori
    Hello, My solution has a library project which needs a special environment to be built (lots of external libraries and tools)... but it is not vital to our application. We'd like to avoid installing these tools when not necessary (most of our developers work on other parts of code). We have created another project which has the same API, but has an empty implementation and is compilable without those external tools. I'd like to be able to easily switch between those projects and still get all the references in other projects correct. I don't know VS/MSBuild very well, but willing to learn whatever is necessary. Is it possible? I am looking for ideas... We're using Subversion, and solutions involving some hacks inside VCS are also welcome.

  • Getting search results from Twitter in php

    - by Mark Mayo
    I'm attempting to put together a little mashup with some twitter APIs. However, the whole area is new to me (I'm more of an embedded developer dabbling). And frustratingly, every tutorial I am trying in Php is either out of date, not doing what it claims to do, it or is broken. Essentially, I just want a nice bit of example code - say, an HTML file, a connection.js for the JQuery magic, and a php file - 'getsearch' which contains the relevant Curl calls to the API to just return the results for a given search term. Followed the tutorial to the letter at http://www.reynoldsftw.com/2009/02/using-jquery-php-ajax-with-the-twitter-api/ and even downloaded the guy's code and chucked it on my webserver, but it just seems to sit there. I'm relatively competent at php and html, but it's the Curl and the JQuery side of things which is new to me, and would appreciate any thoughts, links, or code suggestions. I've attempted reading the API - but even that seems sparse - and several links are broken to their own tutorials, so that's put me off a bit for now.

  • OS monitoring using JAVA

    - by Puneri
    I'm planning to implement a framework for monitoring OS level resources: process network stats cpu info etc using JAVA. I see there is SIGAR API by Spring, which is implemented in native language and JAVA API being provided on top. But I will prefer not to have native stuff in my framework, rather for each OS will write a Java Class which will fetch required OS info by running system commands via JAVA Runtime. So I would like to have inputs/suggestions that one may have seen of not doing this in JAVA and use native app/api/jni. Any example will help for sure. I agree each OS has different commands to get these stats, but will prefer to have a Java Class per OS than have/load native code.

  • Is concatenating with an empty string to do a string conversion really that bad?

    - by polygenelubricants
    Let's say I have two char variables, and later on I want to concatenate them into a string. This is how I would do it: char c1, c2; // ... String s = "" + c1 + c2; I've seen people who say that the "" + "trick" is "ugly", etc, and that you should use String.valueOf or Character.toString instead. I prefer this construct because: I prefer using language feature instead of API call if possible In general, isn't the language usually more stable than the API? If language feature only hides API call, then even stronger reason to prefer it! More abstract! Hiding is good! I like that the c1 and c2 are visually on the same level String.valueOf(c1) + c2 suggests something is special about c1 It's shorter. Is there really a good argument why String.valueOf or Character.toString is preferrable to "" +? Trivia: in java.lang.AssertionError, the following line appears 7 times, each with a different type: this("" + detailMessage);

  • To create new DB connection or not?

    - by Yeti
    I'm running a cron job (every 15 minutes) which takes about a minute to execute. It makes lots of API calls and stores data to the database. Right now I create a mysql connection at the beginning and use the same connection through out the code. Most of the time is spent making the API calls. Will it be more efficient to create a new database connection only when it's time to store the data (below)? Kill the last connection Wait for API call to complete Create new DB connection Execute query Goto 1

  • javan-whenever not writing crontab with Capistrano deploy

    I’ve been trying to get whenever running on an ec2 instance that was created with ec2 on rails. When I deploy with Capistrano it indicates that the crontab was written, but when I log into the server and run crontab -l it does not seem to have been changed. If I go into the release folder and manually run whenever --write-crontab then run crontab -l - it gets updated properly. Any ideas what could be causing this? Capistrano is not indicating any errors so not sure how to debug, have tried a billion permutations and combinations and nothing changes.
