Menakjubkan bukan??? Bagi programmer Java ada rasa rada-rada khawatir dengan kejadian ini termasuk saya sendiri. Pertanyaan yg muncul di benak saya:

1. Apakah Java nanti tetap akan berlanjut Free & Open Source?

2. Apakah Oracle akan membuka kesempatan yg sama terhadap product2 yg telah dikaluarkan oleh Sun?

3. Apakah editor Netbeans tetap juga akan Free?

Jika memang benar-benar Java sudah tidak menjadi Free, akhirnya akan kelihatan belangnya juga product-product OpenSource yg selalu menggembor-gemborkan ke’gratisan’nya tapi lambat laun juga akhirnya commercial juga. Bagaimana tanggapan Anda?

Gosip baru baru ini adalah perusahan besar SUN Microsystems akan dibeli oleh IBM. Dengan begitu produk utama sun yaitu Java dan antek-anteknya dikhawatirkan akan menjadi tidak free dan open source lagi. Hal ini sangat mengkhawatirkan terutama oleh kalangan developer java yang mengandalkan sifatnya yang free dan open source. Bagaimana tanggapan Anda?

Kadang kita pengen ngerti serial number dari hardisk atau motherboard, nah kodingnya itu kayak gini nech

Hardisk Serial Number

import java.io.File;
import java.io.FileWriter;
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class DiskUtils {
private DiskUtils() {  }

public static String getSerialNumber(String drive) {
String result = "";
try {
  File file = File.createTempFile("realhowto",".vbs");
  file.deleteOnExit();
  FileWriter fw = new java.io.FileWriter(file);

  String vbs = "Set objFSO = CreateObject(\"Scripting.FileSystemObject\")\n"
              +"Set colDrives = objFSO.Drives\n"
              +"Set objDrive = colDrives.item(\"" + drive + "\")\n"
              +"Wscript.Echo objDrive.SerialNumber";  // see note
  fw.write(vbs);
  fw.close();
  Process p = Runtime.getRuntime().exec("cscript //NoLogo " + file.getPath());
  BufferedReader input =
    new BufferedReader
      (new InputStreamReader(p.getInputStream()));
  String line;
  while ((line = input.readLine()) != null) {
     result += line;
  }
  input.close();
}
catch(Exception e){
    e.printStackTrace();
}
return result.trim();
}

public static void main(String[] args){
String sn = DiskUtils.getSerialNumber("C");
javax.swing.JOptionPane.showConfirmDialog((java.awt.Component)
     null, sn, "Serial Number of C:",
     javax.swing.JOptionPane.DEFAULT_OPTION);
}
}

Motherboard Serial Number

import java.io.File;
import java.io.FileWriter;
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class MiscUtils {
private MiscUtils() {  }

public static String getMotherboardSN() {
String result = "";
  try {
    File file = File.createTempFile("realhowto",".vbs");
    file.deleteOnExit();
    FileWriter fw = new java.io.FileWriter(file);

    String vbs =
       "Set objWMIService = GetObject(\"winmgmts:\\\\.\\root\\cimv2\")\n"
      + "Set colItems = objWMIService.ExecQuery _ \n"
      + "   (\"Select * from Win32_BaseBoard\") \n"
      + "For Each objItem in colItems \n"
      + "    Wscript.Echo objItem.SerialNumber \n"
      + "    exit for  ' do the first cpu only! \n"
      + "Next \n";

    fw.write(vbs);
    fw.close();
    Process p = Runtime.getRuntime().exec("cscript //NoLogo " + file.getPath());
    BufferedReader input =
      new BufferedReader
        (new InputStreamReader(p.getInputStream()));
    String line;
    while ((line = input.readLine()) != null) {
       result += line;
    }
    input.close();
  }
  catch(Exception e){
      e.printStackTrace();
  }
  return result.trim();
}

public static void main(String[] args){
  String cpuId = MiscUtils.getMotherboardSN();
  javax.swing.JOptionPane.showConfirmDialog((java.awt.Component)
       null, cpuId, "Motherboard serial number",
       javax.swing.JOptionPane.DEFAULT_OPTION);
}
}

First Problem

This is my simple source code to export my jfugue music to MIDI

The midi output open in notation composer, show like this:

Look at the duration, not same with my jfugue string.

Then if I open it in Guitar Pro 5, the tempo become 20. Not 80 again…

Second Problem

This my simple code to export to MusicXML :

If I open OUTPUT.xml in MuseScore become like this :

Then if I open it in Guitar Pro become like this :

This is I use jfugue-4.0.3, note t become q.

Third Problems

My Third problem is for percussions :

Output midi open in notation composer :

Open Oct 22 2008
