Audio Record Using Java

package com.pkm.sound.record;

import java.io.File;

public class AudioRecorder {
    private static final int RECORD_TIME = 6 * 1000;   // 6 seconds
    
    public static void main(String[] args) {
        File wavFile = new File("Record.wav");
        final SoundRecordingUtil recorder = new SoundRecordingUtil();
        Thread recordThread = new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    System.out.println("Start recording...");
                    recorder.start();
                } catch (Exception ex) {
                    ex.printStackTrace();
                    System.exit(-1);
                }              
            }
        });
         
        recordThread.start();
         
        try {
            Thread.sleep(RECORD_TIME);
        } catch (InterruptedException ex) {
            ex.printStackTrace();
        }
         
        try {
            recorder.stop();
            recorder.save(wavFile);
            System.out.println("STOPPED");
        } catch (Exception ex) {
            ex.printStackTrace();
        }
         
        System.out.println("DONE");

Php, convert time between two timezones

<?php
$src_tz = new DateTimeZone('Australia/Melbourne');
$dest_tz = new DateTimeZone('GMT');

$dt = new DateTime("2014-07-06 00:00:00", $src_tz);
echo 'Australia/Melbourne: ' . $dt->format('Y-m-d H:i:s');
$dt->setTimeZone($dest_tz);
echo '<br/>GMT: ' . $dt->format('Y-m-d H:i:s');

$dt = new DateTime("2014-10-06 00:00:00", $src_tz);
echo '<br/><br/>Australia/Melbourne: ' . $dt->format('Y-m-d H:i:s');
$dt->setTimeZone($dest_tz);
echo '<br/>GMT (DST Enabled): ' . $dt->format('Y-m-d H:i:s');
?>

Output

Australia/Melbourne: 2014-07-06 00:00:00
GMT: 2014-07-05 14:00:00

Australia/Melbourne: 2014-10-06 00:00:00
GMT (DST Enabled): 2014-10-05 13:00:00

Grails default version=false to all domain classes

Need to write the following line of code Config.groovy:

grails.gorm.default.mapping = { 
    version false 
}

Request Mocking In Grails For Back-end/Background Threads

import javax.servlet.http.HttpServletRequest
import org.springframework.web.context.request.RequestContextHolder
import org.codehaus.groovy.grails.web.context.ServletContextHolder
import org.springframework.web.context.support.WebApplicationContextUtils

def getRequest() {
    def webRequest = RequestContextHolder.getRequestAttributes();
    if(!webRequest) {
        def servletContext  = ServletContextHolder.getServletContext();
        def applicationContext = WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
        webRequest = grails.util.GrailsWebUtil.bindMockWebRequest(applicationContext);
    }
    return webRequest.request;
}

This code can broke while working on a WAR environment. The problem was that the 
MockWebRequest class was part of the “org.springframework:org.springframework.test:3.0.3.RELEASE” jar 
and had to be included in the BuildConfig.groovy as

dependencies {
    runtime 'org.springframework:org.springframework.test:3.0.3.RELEASE'
}

Ensure that the line:

mavenCentral()


is not commented in BuildConfig.groovy

Strict Standards: Non-static method Configure::getInstance() should not be called

I Got this error as follows:

Strict Standards: Redefining already defined constructor for class Object in C:\Xampp\htdocs\webapp\cake\libs\object.php on line 54

Strict Standards: Non-static method Configure::getInstance() should not be called statically in C:\Xampp\htdocs\webapp\cake\bootstrap.php on line 38

I solved this problem by changing in /cake/bootstrap.php.

FIND:
error_reporting(E_ALL & ~E_DEPRECATED);

REPLACE:
error_reporting(E_ALL & ~E_STRICT & ~E_DEPRECATED);

Grails get bean/service from service or other class

import org.codehaus.groovy.grails.plugins.web.taglib.ApplicationTagLib
import grails.util.Holders
import org.codehaus.groovy.grails.commons.GrailsApplication

public static GrailsApplication grailsApplication = Holders.grailsApplication;
public static ServletContext servletContext = Holders.servletContext;
public static ApplicationTagLib g = Holders.applicationContext.getBean("org.codehaus.groovy.grails.plugins.web.taglib.ApplicationTagLib")

def bean = Holders.applicationContext.getBean(beanIdentifier);
// beanIdentifier = userService, groupService etc...
