  • Face recognition Library

    - by Janusz
    I'm looking for a free face recognition library for a university project. I'm not looking for face detection. I'm looking for actual recognition. That means finding images that contain specified faces or libraries that calculate distances between specific faces. I'm using OpenCV for detecting the faces and a rough Eigenfaces Algorithm for the recognition now. But I thought there should be something out there with a better performance then a self written Eigenfaces Algorithm. I don't talk about speed as performance I'm looking for a library with better results as an simple Eigenfaces approach I took a look at faint but it seems the library is not very reusable for my own applications. I'm happy with a library in Python, Java, C++, C or something like that. The best thing would be if it can be run on a Windowsmachine

  • GWT - How to define a Widget outside layout hierarchy in uibinder xml file

    - by mr_room
    Hello, this is my first post. I hope someone could help me. I'm looking for a way to define a widget in UiBinder XML layout file separately, without being part of the layout hierachy. Here's a small example: <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui"> <g:Label ui:field="testlabel" text="Hallo" /> <g:HTMLPanel> ... </g:HTMLPanel> The compile fails since the ui:UiBinder element expects only one child element. In Java Code i will access and bind the Label widget as usual: @UiField Label testlabel; For example, this could be useful when you define a Grid or FlexTable - i want to define the Labels for the table header within the XML layout file, not programmatically within the code. Many thanks in advance

  • functional-style datatypes in Python

    - by Danny Roberts
    For anyone who's spent some time with sml, ocaml, haskell, etc. when you go back to using C, Python, Java, etc. you start to notice things you never knew were missing. I'm doing some stuff in Python and I realized what I really want is a functional-style datatype like (for example) datatype phoneme = Vowel of string | Consonant of voice * place * manner datatype voice = Voiced | Voiceless datatype place = Labial | Dental | Retroflex | Palatal | Velar | Glottal datatype manner = Stop | Affricate | Fricative | Nasal | Lateral type syllable = phoneme list Does anyone have a particular way that they like to simulate this in Python?

  • When is calculating or variable-reading faster?

    - by Andreas Hornig
    hi, to be honest, I don't really know what the "small green men" in my cpu and compiler do, so I sometimes would like to know :). Currently I would like to know what's faster, so that I can design my code in a more efficient way. So for example I want to calclate something at different points in my sourcecode, when will it be faster to calculate it once and store it in a variable that's read and used for the next points it's needed and when is it faster to calculate it everytime? I think it's depending on how "complex" and "long" the calculation is and how fast then cache is, where variables are stored, but I don't have any clue what's faster :). Thanks for any reply to my tiny but important question! Andreas PS: perhaps it's important to know that I code in JAVA, but it's more a genral question.

  • Practical guide to programming paradigms ?

    - by Pierre
    I think I might be misunderstanding the whole thing and I am looking for some programming wisdom. When faced with a programming challenge, I feel the most important question is "which programming paradigm(s) are better suited to handle it, and how to apply them". A distant second is "which language to use". Yet it seems that most of the programming related content I stumble upon on the Internet has it exactly backwards and focuses mostly on the language choice. An object-oriented solution is fundamentaly the same, whether it's implemented in c++, Java or PHP... So where is the paradigm centered content? Where is the "practical guide to programming paradigms and implementations" and other literature helping bringing real-world and programming concepts together? Note: I already know about "Programming Paradigms for Dummies: What Every Programmer Should Know" from Peter Van Roy.

  • URL BNF search part does not make sense

    - by Asaf Mesika
    Hi, While implementing a Java regular expression for URL based on the URL BNF published by W3C, I've failed to understand the search part. As quoted: httpaddress h t t p : / / hostport [ / path ] [ ? search ] search xalphas [ + search ] xalphas xalpha [ xalphas ] xalpha alpha | digit | safe | extra | escape alpha a | b | c | d | e | f | g | h | i | j | k | l | m | n | o | p | q | r | s | t | u | v | w | x | y | z | A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | digit 0 |1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 safe $ | - | _ | @ | . | & | + | - extra ! | * | " | ' | ( | ) | , Search claims it is xalphas seperated by a plus sign. xalphas can contain plus signs by it self, as claimed by safe. Thus according to my understanding , it should be: search xalphas Where am I wrong here?

  • What technical skills needed for algorithmic trading, HFT, etc?

    - by alchemical
    I'm interested in getting into developing trading systems, black box, HFT, etc. My primary experience is with C# and .Net (7 years). I've also done some sockets programming. I have some experience in finance working on analysis applications (2 years). My goal is to move into developing automated trading systems for a hedge fund, bank, etc. Is there any way to learn the skills needed for this without somehow getting the job first? I've looked at the open source tradelink, IB interactive brokerage, etc. I'm playing around with this framework, and may hook it up and do some paper trading. However, I'm not sure if this has much relationship with how a well-funded entity would be conducting a high-level automated trading operation. I.e. would the tools and frameworks they prefer be a totally different skill-set? Also wondering if I need to learn C++ and/or Java for these types of apps.

  • Android programming - How to acces [to draw on] XML view in main.xml layout, using code

    - by user556248
    Ok I'm a newbie at Android programming, have a hard time with the graphics part. Understand the beauty of creating layout in XML file, but lost how to access various elements, especially a View element to draw on it. See example of my layout main.xml here; <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/root" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content"> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/Title" android:text="App title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textColor="#000000" android:background="#A0A0FF"/> </LinearLayout> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/PaperLayout" android:layout_width="fill_parent" android:layout_height="0dp" android:layout_weight="1" android:orientation="horizontal" android:focusable="true"> <View android:id="@+id/Paper" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:id="@+id/File" android:layout_width="fill_parent" android:layout_weight="1" android:layout_height="34dp" android:layout_alignParentTop="true" android:layout_centerInParent="true" android:clickable="true" android:textSize="10sp" android:text="File" /> <Button android:id="@+id/Edit" android:layout_width="fill_parent" android:layout_weight="1" android:layout_height="34dp" android:clickable="true" android:textSize="10sp" android:text="Edit" /> </LinearLayout> </LinearLayout> As you can see I have a custom app title bar, then a View filling middle, and finally two buttons in bottom. Catching button events and responding to, for example changing title bar text and changing View background color works fine, but how the heck do I access and more importantly draw on the view defined in main.xml UPDATE: That for your suggestion, however besides that I need a View, not ImageView and you are missing a parameter on canvas.drawText and an ending bracket, it does not work. Now this is most likely because you missed the fact that I am a newbie and assuming I can fill in any blanks. Now first of all I do NOT understand why in my main.xml layout file I can create a View or even a SurfaceView element, which is what I need, but according to your solution I don't even specify the View like Anyways I edited my main.xml according to your solution, and slimmed it down a bit for simplicity; <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/root" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content"> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/Title" android:text="App title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textColor="#000000" android:background="#A0A0FF"/> </LinearLayout> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/PaperLayout" android:layout_width="fill_parent" android:layout_height="0dp" android:layout_weight="1" android:orientation="horizontal" android:focusable="true"> <com.example.MyApp.CustomView android:id="@+id/Paper" android:layout_width="fill_parent" android:layout_height="fill_parent" /> <com.example.colorbook.CustomView/> </LinearLayout> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:id="@+id/File" android:layout_width="fill_parent" android:layout_weight="1" android:layout_height="34dp" android:layout_alignParentTop="true" android:layout_centerInParent="true" android:clickable="true" android:textSize="10sp" android:text="File" /> </LinearLayout> </LinearLayout> In my main java file, MyApp.java, I added this after OnCreate; public class CustomView extends ImageView { @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); canvas.drawText("Your Text", 1, 1, null); } } But I get error on the "CustomView" part; "Implicit super constructor ImageView() is undefined for default constructor.Must define an explicit constructor" Eclipse suggests 3 quick fixes about adding constructor, but none helps, well it removes error but gives error on app when running. I hope somebody can break this down for me and provide a solution, and perhaps explain why I can't just create a View element in my main.xml layotu file and draw on it in code.

  • springTestContextBeforeTestMethod failed in Maven spring-test

    - by joejax
    I try to setup a project with spring-test using TestNg in Maven. The code is like: @ContextConfiguration(locations={"test-context.xml"}) public class AppTest extends AbstractTestNGSpringContextTests { @Test public void testApp() { assert true; } } A test-context.xml simply defined a bean: <bean id="app" class="org.sonatype.mavenbook.simple.App"/> I got error for Failed to load ApplicationContext when running mvn test from command line, seems it cannot find the test-context.xml file; however, I can get it run correctly inside Eclipse (with TestNg plugin). So, test-context.xml is under src/test/resources/, how do I indicate this in the pom.xml so that 'mvn test' command will work? Thanks, UPDATE: Thanks for the reply. Cannot load context file error was caused by I moved the file arround in different location since I though the classpath was the problem. Now I found the context file seems loaded from the Maven output, but the test is failed: Running TestSuite May 25, 2010 9:55:13 AM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions INFO: Loading XML bean definitions from class path resource [test-context.xml] May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext prepareRefresh INFO: Refreshing org.springframework.context.support.GenericApplicationContext@171bbc9: display name [org.springframework.context.support.GenericApplicationContext@171bbc9]; startup date [Tue May 25 09:55:13 PDT 2010]; root of context hierarchy May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext obtainFreshBeanFactory INFO: Bean factory for application context [org.springframework.context.support.GenericApplicationContext@171bbc9]: org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99 May 25, 2010 9:55:13 AM org.springframework.beans.factory.support.DefaultListableBeanFactory preInstantiateSingletons INFO: Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99: defining beans [app,org.springframework.context.annotation.internalCommonAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor]; root of factory hierarchy Tests run: 3, Failures: 2, Errors: 0, Skipped: 1, Time elapsed: 0.63 sec <<< FAILURE!

UPDATE: I think I got the problem (still don't know why) - Whenever I extends AbstractTestNGSpringContextTests or AbstractTransactionalTestNGSpringContextTests, the test will failed with this error: Failed tests: springTestContextBeforeTestMethod(org.sonatype.mavenbook.simple.AppTest) springTestContextAfterTestMethod(org.sonatype.mavenbook.simple.AppTest) So, eventually the error went away when I override the two methods. I don't think this is the right way, didn't find much info from spring-test doc. If you know spring test framework, please shred some light on this.

  • Python "Every Other Element" Idiom

    - by Matt Luongo
    Hey guys, I feel like I spend a lot of time writing code in Python, but not enough time creating Pythonic code. Recently I ran into a funny little problem that I thought might have an easy, idiomatic solution. Paraphrasing the original, I needed to collect every sequential pair in a list. For example, given the list [1,2,3,4,5,6], I wanted to compute [(1,2),(3,4),(5,6)]. I came up with a quick solution at the time that looked like translated Java. Revisiting the question, the best I could do was l = [1,2,3,4,5,6] [(l[2*x],l[2*x+1]) for x in range(len(l)/2)] which has the side effect of tossing out the last number in the case that the length isn't even. Is there a more idiomatic approach that I'm missing, or is this the best I'm going to get?

  • SublimeJava won't react at all on Mac OS X 10.7

    - by David Merz
    today I tried to install and run the SublimeJava Plugin for Sublime Text 2. Here is basically what i've done. Cloning the git Repository https://github.com/quarnster/SublimeJava.git into ~/Library/Application Support/Sublime Text 2/Packages. Created a ProjectFile to test the Plugin. { "folders": [ { // The class files are in the same directory "path": "~/src/path_to_project/" } ], "settings": [ { "sublimejava_classpath": [ "~/src/path_to_project/", "/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Libraries/" ], "sublimejava_enabled":true } ] } Now whenever I type something that should trigger the code-completion, nothing happens.

  • Forth: free video tutorials?

    - by Peter Mortensen
    Can you recommend any free Forth video tutorials (except for following) ? The only one I know of is Samuel A. Falvo's excellent "Over The Shoulder Episode 1: Text Preprocessing in Forth". MPEG. 102 MB. There are also videos from the annual Forth Day, but I don't consider those to be tutorials. (Unfortunately Forth is, like R, C, C++, Java, C#, D, COM, .NET, F# and Frontier, an unspecific search term. Search tip for Forth: qualify it with "ans" - as in ANS Forth, the ANSI Forth Standard.)

  • Style: Dot notation vs. message notation in Objective-C 2.0

    - by groundhog
    In Objective-C 2.0 we got the "dot" notation for properties. I've seen various back and forths about the merits of dot notation vs. message notation. To keep the responses untainted I'm not going to respond either way in the question. What is your thought about dot notation vs. message notation for property accessing? Please try to keep it focused on Objective-C - my one bias I'll put forth is that Objective-C is Objective-C, so your preference that it be like Java or JavaScript aren't valid. Valid commentary is to do with technical issues (operation ordering, cast precedence, performance, etc), clarity (structure vs. object nature, both pro and con!), succinctness, etc. Note, I'm of the school of rigorous quality and readability in code having worked on huge projects where code convention and quality is paramount (the write once read a thousand times paradigm).

  • ajax in zend frame work

    - by rookie
    Hi, I am new to Zend Frame Work. I am using $ajaxContext = $this-_helper-getHelper('AjaxContext'); for adding action contexts. I have one Index.phtml page and all other views are ajax.phtml pages. I have to do some java script methods in the ajax.phtml pages. But i didn't find a way to refer the js files in the ajax.phtml pages. I have tried adding those in the controller init and index action, using $this-view-headScript()-appendFile, though i have the reference added in the page source, none of htese seems to be working on the ajax content. Then i tried to add it in the action for the ajax page, then it is not coming in the page source itself. As far as i understood, $this-view-headScript()-appendFile will append the file reference to the layout page and for the ajax.phtml pages, the layout will be disabled. Is there any way that i can refer my js files in the ajax.phtml pages?

  • Uploading images to a PHP server from Android

    - by Samuh
    I need to upload an image to a remote PHP server which expects the following parameters in HTTPPOST: *$_POST['title']* *$_POST['caption']* *$_FILES['fileatt']* Most of the internet searches suggested either : Download the following classes and trying MultiPartEntity to send the request: apache-mime4j-0.5.jar httpclient-4.0-beta2.jar httpcore-4.0-beta3.jar httpmime-4.0-beta2.jar OR Use URLconnection and handle multipart data myself. Btw, I am keen on using HttpClient class rather than java.net(or is it android.net) classes. Eventually, I downloaded the Multipart classes from the Android source code and used them in my project instead. Though this can be done by any of the above mentioned methods, I'd like to make sure if these are the only ways to achieve the said objective. I skimmed through the documentation and found a FileEntity class but I could not get it to work. What is the correct way to get this done in an Android application? Thanks.

  • How-to configure Spring Social via XML

    - by Matthias Steiner
    I spend a few hours trying to get Twitter integration to work with Spring Social using the XML configuration approach. All the examples I could find on the web (and on stackoverflow) always use the @Config approach as shown in the samples For whatever reason the bean definition to get an instance to the twitter API throws an AOP exception: Caused by: java.lang.IllegalStateException: Cannot create scoped proxy for bean 'scopedTarget.twitter': Target type could not be determined at the time of proxy creation. Here's the complete config file I have: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util" xmlns:cxf="http://cxf.apache.org/core" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.1.xsd"> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <jee:jndi-lookup id="dataSource" jndi-name="java:comp/env/jdbc/DefaultDB" /> <!-- initialize DB required to store user auth tokens --> <jdbc:initialize-database data-source="dataSource" ignore-failures="ALL"> <jdbc:script location="classpath:/org/springframework/social/connect/jdbc/JdbcUsersConnectionRepository.sql"/> </jdbc:initialize-database> <bean id="connectionFactoryLocator" class="org.springframework.social.connect.support.ConnectionFactoryRegistry"> <property name="connectionFactories"> <list> <ref bean="twitterConnectFactory" /> </list> </property> </bean> <bean id="twitterConnectFactory" class="org.springframework.social.twitter.connect.TwitterConnectionFactory"> <constructor-arg value="xyz" /> <constructor-arg value="xzy" /> </bean> <bean id="usersConnectionRepository" class="org.springframework.social.connect.jdbc.JdbcUsersConnectionRepository"> <constructor-arg ref="dataSource" /> <constructor-arg ref="connectionFactoryLocator" /> <constructor-arg ref="textEncryptor" /> </bean> <bean id="connectionRepository" factory-method="createConnectionRepository" factory-bean="usersConnectionRepository" scope="request"> <constructor-arg value="#{request.userPrincipal.name}" /> <aop:scoped-proxy proxy-target-class="false" /> </bean> <bean id="twitter" factory-method="?ndPrimaryConnection" factory-bean="connectionRepository" scope="request" depends-on="connectionRepository"> <constructor-arg value="org.springframework.social.twitter.api.Twitter" /> <aop:scoped-proxy proxy-target-class="false" /> </bean> <bean id="textEncryptor" class="org.springframework.security.crypto.encrypt.Encryptors" factory-method="noOpText" /> <bean id="connectController" class="org.springframework.social.connect.web.ConnectController"> <constructor-arg ref="connectionFactoryLocator"/> <constructor-arg ref="connectionRepository"/> <property name="applicationUrl" value="https://socialscn.int.netweaver.ondemand.com/socialspringdemo" /> </bean> <bean id="signInAdapter" class="com.sap.netweaver.cloud.demo.social.SimpleSignInAdapter" /> </beans> What puzzles me is that the connectionRepositoryinstantiation works perfectly fine (I commented-out the twitter bean and tested the code!) ?!?

  • What is best way to update digital certificates from server to many clients when certificate expires

    - by pramodc84
    One of my friend is working on issue related to updating expired digital certificates. He is working on Java application(Swings I guess), which has 4000 clients. All those need a digital certificate to connect to the application and this certificate expires every year. At the end of year he needs to update the certificate credentials for all clients. Currently this is manual process, done by connecting to each of 4000 systems either locally or by remote connection. He is got task to convert this process to be an automated process. Please suggest some solutions.

  • Documenting user scenarios and measuring/testing

    - by Rimian
    Please forgive me as I don't quite remember the exact terms for what I am talking about... hence my question. Recently I worked on a large Agile team where I encountered a method of defining user scenarios (much like user stories). These scenarios were a few very basic short sentences with keywords and a structure that could be understood by humans (especially project managers) and could also be coded against using some Java Framework (for verifying tests). The exact structure of this mini language used keywords like "when" and "and" or "if" which was how the framework parsed and verified the result. The purpose of this framework was to interface between management and the acceptance testing framework. So essentially management could write the tests themselves using English. The scenario went something like this: "When a user visits URL and User clicks on X Something happens (that can be measured)" Can anyone help me remember exactly what I am talking about? Many thanks

  • I want to port my delicious bookmarks to my website

    - by puneet
    I started building a app that will automatically download my delicious bookmarks, and save to a database, so they I can view them on my own website in my favoured format. I am forced to use oAuth, as I have a yahoo id to login to delicious. The problem is I am stuck at the point where oAuth requires a user to manually go and authenticate. Is there a code/ guidelines available anywhere I can follow? All I want is a way to automatically save my bookmarks to my database. Any help is appreciated. I can work on java, .net and php. Thanks.

  • Knowledge base web app -- need a demo mode

    - by Smandoli
    I was contracted to build an on-line knowledge base that searches and cross-references many thousands of replacement parts for a niche industry. My client furnishes this app to his customers on a subscription basis. It uses MySQL and PHP and it works great. I want to deploy it in "demo mode" to sell my skills. I want the user to see the functions, but I have to guard the data for my client. My first idea was to obfuscate the results. That's at cross-purposes with showing how well it searches. I'm considering a limit on how many searches you can perform, but that's awkward too as someone could visit every day and get more answers than we would prefer. Other posts I've found are about letting people interact with an app, but without the challenge of protecting a big knowledge base. Can you suggest an approach? (Note, I put the tag obfuscation, but not sure it applies because java code obfuscation seems to be unrelated.)

  • Method signature Vs function prototype

    - by Maroloccio
    A formal definition of the two? Current Wiki articles denote their different contexts and applications, such as internal type signature "strings" in Java VMs (1) and C/C++ function prototypes informing compilers of upcoming method definitions (2) but... 1) http://en.wikipedia.org/wiki/Type_signature 2) http://en.wikipedia.org/wiki/Function_prototype ... where to look for a definition which clearly and formally distinguished one from the other? There is literature using the words prototype and signature almost interchangeably yet other uses appear strict and consistent, if language-specific. Background: I am writing documentation for a sample compiler written for a University project.

  • Writing a Jeweler Rakefile that adds dependencies depending on RUBY_ENGINE (ruby or jruby)

    - by Matt Zukowski
    I have a Rakefile that includes this: Jeweler::Tasks.new do |gem| # ... gem.add_dependency('json') end The gemspec that this generates builds a gem that can't be installed on jruby because the 'json' gem is native. For jruby, this would have to be: Jeweler::Tasks.new do |gem| # ... gem.add_dependency('json-jruby') end How do I conditionally add the dependency for 'json-jruby' when RUBY_ENGINE == 'java'? It seems like my only option is to manually edit the gemspec file that jeweler generates to add the RUBY_ENGINE check. But I'd rather avoid this, since it kind of defeats the purpose of using jeweler in the first place. Any ideas?

  • How to dynamic adjust the width of columns in Table layout

    - by michael
    Hi, I create a TableLayout which has 3 equally-wide columns (I put 'stretchColumns="*" in my TableLayout which has 3 TextViews). See below: But my questions is why I set one of the TextView to 'visibility' to Gone in my java code, the TableLayout does not re-size to 2 qually-wide columns which fit the whole screen. I have even call 'tableLayout.requestLayout()' after i set the visibility to Gone.' How can I achieve what I want? Thank you. <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/textpanel" android:stretchColumns="*"> <TableRow android:layout_width="fill_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/text1" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <TextView android:id="@+id/text2" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <TextView android:id="@+id/text3" android:layout_width="fill_parent" android:layout_height="wrap_content"/> </TableRow> </TableLayout>
