solution:

Install cygwin, search mingw64 and mark the mingw64 x86_64 gcc core module
replace mexopt.bat with: https://gist.github.com/1579415

BOOTABLE USB Tidak bisa Jalan Saat Booting

Bootable usb berguna untuk menginstall operating system(os) tanpa menggunakan CD installer, cocok untuk netbook / laptop / pc yang tidak memiliki optical drive. ada banyak software untuk membuat bootable usb seperti yumi, xboot, universal usb installer, liveusb install, dll.
bagi anda yang menggunakan software yumi, xboot, universal usb installer, liveusb install, dll tetapi tidak berhasil pada saat booting atau hanya muncul blank screen, mungkin masalahnya terletak pada flaskdisknya, karena ada beberapa flaskdisk yang tidak support untuk menjadi bootable usb, coba untuk memformat flaskdisk anda menggunakan diskpart, langkahnya sbb:
buka cmd lalu ketik:
1. diskpart
2. list disk - temukan nomor disk untuk flaskdisk
3. select disk ? - ? = nomor usb drive agan cth: select disk 2 (hati2 jgn smpe salah)
4. clean
5. create partition primary
6. select partition 1
7. active
8. format fs=fat32
9. assign
10. exit
jalankan software bootable usb seperti biasa, lalu coba booting melalui flaskdisk yang telah terinstall.

PHP: Last Three Days Of Month

Kemarin ada temen saya yang menanyakan bagaimana cara mencari 3 hari terakhir pada bulan dari tanggal yang di tentukan, setelah mencoba2 akhirnya ketemu juga solusinya..
- pertama cari dulu batas akhirnya atau first day of next month-nya:

//contoh data bulan dan tahun yang saya ambil dari fungsi time()
$t=explode('/',date('m/Y',time()));
//mencari first day of month menggunakan mktime dan strtotime
$firstDayNextMonth= strtotime("+1month",mktime(0, 0, 0, $t[0], 1, $t[1]));

- setelah itu cari batas awalnya:

//first day of last three days of month
$x = strtotime("-3day",$firstDayNextMonth);
//atau langsung seperti ini
$x= strtotime("+1month -3day",mktime(0, 0, 0, $t[0], 1, $t[1]));

sekian dan terimakasih :)

Mengenal Metode MVC (Model-View-Controller)

MVC adalah Sebuah Metode Pengembangan Aplikasi dengan Membagi aplikasi menjadi 3 layer yaitu layer Model, Layer View, dan Layer Controller

Layer Model adalah layer yang bertugas mengolah data atau memanipulasi data sesuai dari bisnis proses yang terjadi pada data tersebut.
Layer View adalah layer yang merepresentasikan data dalam bentuk tampilan dan menuntun alur interaksi user terhadap aplikasi.
Layer Controller adalah layer yang menghubungkan antara Layer Model dengan Layer View dan bertanggungjawab mengatur alur transisi antar kedua layer tersebut.

Berikut gambaran Metode MVC:

implementasi datatables di codeigniter

menggunakan plugin datatables pada codeigniter kini semakin mudah, karena sudah ada library khusus codeigniter :))

asumsi :

- sudah install xampp

- sudah install codeigniter

-sudah install jquery

- sudah install file2 datatables di codeigniter

file yang dibutuhkan:

- library Datatables: datatables.php

berikut langkah2nya :

- buat database dan tabel beserta isinya. contoh saya membuat tabel obat:

- lalu set database name sesuai dengan nama database yang kamu buat di 'application/config/database.php

- buat file controller dgn nama misal 'testControl' dengan isi sebagai berikut:

?

<?php
class testControl extends CI_Controller
{
    function view_obat()
  {
   $this->load->view('view_obat');
  }
    function ajax_view_obat()
  {
   $this->load->library('Datatables');
   $this->datatables->from('obat');
   $this->datatables->select('kode_obat,nama_obat,kode_satuan,kode_supplier');
   echo $this->datatables->generate();
  }
}
//end of file testControl

- buat view dengan nama 'view_obat' dengan isi sbb:

?

   <link rel="stylesheet" type="text/css" media="screen" href="<?php echo base_url(); ?>lib/css/demo_table.css"/>
</head>
<body>
<h2>data obat</h2>
<hr>
<table id="tbl" cellpadding="0" cellspacing="0" border="0" class="display" >
  <thead>
   <tr>
    <th>kode obat</th>
    <th>nama obat</th>
    <th>kode satuan</th>
    <th>kode supplier</th>
   </tr>
  </thead>
  <tbody>
   <tr>
    <td colspan="5" class="dataTables_empty">Loading data from server</td>
   </tr>
  </tbody>
  <tfoot>
   <tr>
   </tr>
  </tfoot>
</table>
  <script type="text/javascript" charset="utf-8">
  $(document).ready(function() {
   $('#tbl').dataTable( {
    "bProcessing": true,
    "bServerSide": true,
    'sPaginationType': 'full_numbers',
    "sAjaxSource": "<?=base_url()?>index.php/testControl/ajax_view_obat/",
    "aaSorting": [[ 0, "desc" ]]
   } );
  } ); </script>
</body>

- dan hasilnya sebagai berikut:

- selesai, selamat mencoba :))
