• Getting Wikipedia infoboxes in a format that Ruby can understand

  - by hadees

  I am trying to get the data from Wikipedia's infoboxes into a hash or something so that I can use it in my Ruby on Rails program. Specifically I'm interested in the Infobox company and Infobox person. The example I have been using is "Ford Motor Company". I want to get the company info for that and the person info for the people linked to in Ford's company box. I've tried figuring out how to do this from the Wikipedia API or DBPedia but I haven't had much luck. I know wikipedia can return some things as json which I could parse with ruby but I haven't been able to figure out how to get the infobox. In the case of DBPedia I am kind of lost on how to even query it to get the info for Ford Motor Company.

• Given GPS coordinates, how do I find nearby landmarks or points-of-interest?

  - by stackoverflowuser2010

  I just bought a Google Nexus One smartphone, and I want to write a small Android application for fun. Suppose I can get my current GPS coordinates, so then how can I programmatically find nearby landmarks or points-of-interest within some radius? Is there an API to get GPS geo-tagged landmarks, like in Google Earth's database? For example, if I'm in downtown Chicago, my program would point me to all the "tourist" things to visit in that city. Ideally, it would all run on my smartphone, but if necessary, I can have the smartphone query a webserver, which would then run more queries.

• Extract XML name/value pairs from different nodes in Coldfusion

  - by Ryan French

  Hi All, I am working on some Plesk integration using the XML API and I am trying to figure out how to parse the XML response that I get back. Most of the data is fine, but the Limits and Permissions are setout differently. Essentially they are set out like so: <data> <limits> <limit> <name>foo</name> <value>bar</value> </limit> <limit> <name>foo2</name> <value>bar2</value> </limit> </limits> </data> How do I extract 'bar' from the xml given that I know I want the value of 'foo', but not the value of 'foo2'?

• Chrome Extension: How to display tab objects?

  - by Jalleluhah

  I am in the process of designing an extension for Google Chrome that helps to organize tabs (I know, there are many that already exist; that doesn't matter). I wish to open a popup window that will display tabs as objects (i.e., in the same way that it is displayed in the tab bar at the top of the browser). One way of doing this would be to pull various details (ID, Title, URL, etc.) from each tab, create a class and make instantiations of it upon the opening of each tab using these data, but this seems rather convoluted considering that what I want is sitting right there in the tab bar. Is there any simpler way to achieve this? In addition, I have seen several apps that utilize page previews. Is there something in the API that allows direct access to these?

• Is there a good reflection library available for Scala?

  - by Erik Engbrecht

  I'm working on a library that needs reflection, and needs Scala-specific information as opposed to what is available via the standard Java reflection API. Right now I'm using the undocumented code in scalap (the Scala equivalent to javap) and trying to associate the data it provides with Java reflection objects so that I can call methods and such (scalap just parses class files). I found this but there's nothing there... https://github.com/dubochet/scala-reflection ...and I've searched the Scala SVN repo for traces of it and failed to find it there, either (but it could be I just missed it). Does anyone know of a Scala reflection library that provides information similar to what scalap provides but also allows you to call methods, access fields, etc like the Java reflection library?

• Question about tracking user in a map application using cellid

  - by subh

  I am trying to understand the concept of cellid (http://www.opencellid.org/api) As per that, if we send a request http://www.opencellid.org/cell/get?key=myapikey&mnc=1&mcc=2&lac=200&cellid=234 it will respond with the latitude and longitude. I was wondering if this can be used from within a google map application for tracking a user or it needs to be used from within a mobile device? If it can be used from within a web app, what parameters should it use for mcc: mobile country code (decimal) mnc: mobile network code (decimal) lac: locale area code (decimal) cellid: value of the cell id E.g., will it work if we know the cell number of the person(e.g., 281 222 6700)

• Sending the variable's content to my mailbox in Python?

  - by brilliant

  I have asked this question here about a Python command that fetches a URL of a web page and stores it in a variable. The first thing that I wanted to know then was whether or not the variable in this code contains the HTML code of a web-page: from google.appengine.api import urlfetch url = "http://www.google.com/" result = urlfetch.fetch(url) if result.status_code == 200: doSomethingWithResult(result.content) The answer that I received was "yes", i.e. the variable "result" in the code did contain the HTML code of a web page, and the programmer who was answering said that I needed to "check the Content-Type header and verify that it's either text/html or application/xhtml+xml". I've looked through several Python tutorials, but couldn't find anything about headers. So my question is where is this Content-Type header located and how can I check it? Could I send the content of that variable directly to my mailbox? Here is where I got this code. It's on Google App Engines.

• Django - transactions in the model?

  - by orokusaki

  Models (disregard typos / minor syntax issues. It's just pseudo-code): class SecretModel(models.Model): some_unique_field = models.CharField(max_length=25, unique=True) # Notice this is unique. class MyModel(models.Model): secret_model = models.OneToOneField(SecretModel, editable=False) # Not in the form spam = models.CharField(max_length=15) foo = models.IntegerField() def clean(self): SecretModel.objects.create(some_unique_field=self.spam) Now if I go do this: MyModel.objects.create(spam='john', foo='OOPS') # Obviously foo won't take "OOPS" as it's an IntegerField. #.... ERROR HERE MyModel.objects.create(spam='john', foo=5) # So I try again here. #... IntegrityError because SecretModel with some_unique_field = 'john' already exists. I understand that I could put this into a view with a request transaction around it, but I want this to work in the Admin, and via an API, etc. Not just with forms, or views. How is it possible?

• How can I use Java to communicate to device through USB port?

  - by Bopha

  I just recently learn Java and try to communicate to the device through USB port connection. I've have used C# with OpenNETCF which allows me to send file and retrieve file on the device through USB port; how can I achieve this with java? I seearch on stackoverflow thread, http://stackoverflow.com/questions/544507/how-to-communicate-with-a-usb-device-under-windows-and-java, the comment made by christoffer is to hack the native code, but I don't quite which native code api that he referred to. RAPI, maybe?

• Is ruby ||= intelligent?

  - by brad

  I have a question regarding the ||= statement in ruby and this is of particular interest to me as I'm using it to write to memcache. What I'm wondering is, does ||= check the receiver first to see if it's set before calling that setter, or is it literally an alias to x = x || y This wouldn't really matter in the case of a normal variable but using something like: CACHE[:some_key] ||= "Some String" could possibly do a memcache write which is more expensive than a simple variable set. I couldn't find anything about ||= in the ruby api oddly enough so I haven't been able to answer this myself. Of course I know that: CACHE[:some_key] = "Some String" if CACHE[:some_key].nil? would achieve this, I'm just looking for the most terse syntax.

• Enable access for assistive device programmatically

  - by Dheeraj

  Hi All, I want to enable Access for assistive devices in System Preferences programmatically. But Problem is that my application is not running as root user and i do not want my application to be as root user and also should not ask for any authentication in between. I want to tap all keyboard events globally. I am using CGEventTapCreate() for the same.In the documentation of CGEventTapCreate() API it is mentioned that, Event taps receive key up and key down events if one of the following conditions is true: The current process is running as the root user. Access for assistive devices is enabled. In Mac OS X v10.4 & later, you can enable this feature using System Preferences, Universal Access panel, Keyboard view. I tried manually by checking the Enable Access for assistive devices from System Preference and it gives me expected output. So is there any way to do the same via program without asking for authentication and also application is not running as root user? Thanks, Dheeraj.

• How are java.lang.Object's protected methods protected from subclasses?

  - by Adrian Lang

  The keyword protected grants access to classes in the same package and subclasses (http://java.sun.com/docs/books/tutorial/java/javaOO/accesscontrol.html). Now, every class has java.lang.Object as superclass (http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Object.html). Hence I conclude that every class may access java.lang.Object's methods even if they are protected. Take a look at the following example: public class Testclass { public Object getOne() throws CloneNotSupportedException { return this.clone(); } public Object getTwo() throws CloneNotSupportedException { return ((Object) this).clone(); } } While getOne() compiles fine, getTwo() gives Testclass.java:6: clone() has protected access in java.lang.Object return ((Object) this).clone(); I neither understand why getTwo() doesn't compile nor what's the difference (regarding the access of java.lang.Objects members) with getOne().

• Automatic VM deployment

  - by Robert Wilson

  I have an idea to streamline deployments of prototypes within our team using VMs. The idea would be that a developer would be able to deploy their artifacts to Maven, then use a Web interface to pull them onto a development VM for integration/regression testing. They would then be able to to push those artifacts to a reference system, and finally onto production. I'm currently thinking of doing this myself using the vSphere Java API ( http://vijava.sourceforge.net/ ), and some simple scripting to grab artifacts from the Maven repository, configuration from SVN, and then start up a JBoss server. It feels like the kind of thing that may already be available though, has anyone heard of something similar?

• How to gain greater control of network packets on Android

  - by mauvehead

  I'm looking to design an application that will require some deep control over IP packets. Looking over the reference guide on the developers site at Android I see very limited control over packets from java.net:SocketOptions and java.net:DatagramPacket. Specifically I'm looking to control the individual bits within the packet to set TCP Flags, SYN/ACK/RST, and so forth. Based on the docs I am assuming I cannot do this within the Java API provided by Android and I'm guessing I'll have to do it some other way? Anyone have any insight on this?

The Footer text doesn't appear to be printing. If I check the PageSetup.RightFooter property, I can see the expected Page Number in the Footer. That Page Number doesn't appear anywhere on the printed output sheet. When I print using Excel, though, they appear. Does anyone know why my Footer text is not appearing? Here's my code.

• unable to cope with the asynchronous nature of navigator.geolocation.

  - by Raja

  Hi all I'm using the navigator.geolocation.getCurrentPosition(function) api in firefox 3.6. When i try to call this method repeatedly I see that sometimes it works and sometimes it doesn't. I figured that the problem is because of its asynchronous callback nature. I can see that the callback function is being called at some point but my outer function is already exiting so i cannot catch the values of the position coordinates. I'm pretty new to javascript so i'm assuming other javascript coders might have already figured out how to deal with it. Please help. Thanks

• Correct ifdef for DWORD_PTR, INT_PTR, LONG_PTR, UINT_PTR, ULONG_PTR etc?

  - by user9876

  There are some new integer types in the Windows API to support Win64. They haven't always been suppoprted; e.g. they aren't present in MSVC6. How can I write an #if condition to detect if these types are supported by <windows.h>? (My code needs to compile under many different versions of Microsoft Visual C++, including MSVC6. So I need to provide my own definitions of these types, with an #if to disable them in newer compilers).

• How to include NetBeans Platform Source code into module dependencies

  - by Ben Hammond

  I am debugging a NetBeans Platform application. I have downloaded the NetBeans Platform source code .zip file. I would really really like to attach the source code to the debugger so that I can seamlessly jump to internal NB source code. Normally I would edit the Library configuration to tell NB where to find the source code, and it would just work. However this is not possible for NetBeans Modules; when I look at the Utilities API module dependency it does not look like a normal NB library and there is nowhere to add in the source code. I suspect that if I were to rebuild my project using Maven this would work automatically. But thats a terrible reason to switch to maven. How can I get the NB Platform Source code included into my Module Dependencies ?

• Consume restful webservice through web proxy

  Hello, I'm trying to consume a restful webservice in java using the Apache Wink framework through my school web proxy requiring authentification ClientConfig clientConfig = new ClientConfig(); clientConfig.proxyHost("proxy.school.com"); clientConfig.proxyPort(3128); //nothing to set username and password :( RestClient client = new RestClient(clientConfig); Resource resource = client.resource("http://vimeo.com/api/v2/artist/videos.xml"); String response = resource.accept("text/plain").get(String.class); I've also tried to use the BasicAuthSecurityHandler but it seems to be used to authenticate directly to a web server, not the web proxy BasicAuthSecurityHandler basicAuthHandler = new BasicAuthSecurityHandler(); basicAuthHandler.setUserName("username"); basicAuthHandler.setPassword("password"); config.handlers(basicAuthHandler); It still fail with a HTTP 407 error code : Proxy Authentication Required. I've googled the best I could, nothing came up better to consume a webservice from a Java client through a web proxy, if someone has another idea, feel free to respond
