cheuw — Sat, 14 Aug 2010 14:27:11 +0000

Eventhough they are in hiatus and will debut in Japan in next month, i dunno why this teaser come out from some site. CD ITNW 1st Concert will release soon maybe.. (i hope so,^^). Yeah, The audio teasers were posted on a Korean website that had no further information on what the teasers were exactly for. It can be assumed that they are for their live concert album.

Each teaser lasts around 20 seconds, with Taeyeon singing Hush Hush (The Pussycat Dolls), Tiffany singing Umbrella (Rihanna ft. Jay Z), and Jessica singing Barbie Girl (Aqua).

Although we must update status less than 140 character but its okay. I dunn mind it..xD I meet so many people in twitter. Meet sones. (meet in here not in real life but still in cyber life) but its really having fun to know everyone who have the same hobbies with me or like some idol.

After all, I forget to this blog. Because I am so lazy with anything.xD I dunno what to post and how to post in here anymore. Really stuck! And I have no idea to resolve my problem. If I think deeper again, its really wasteful to pay the hosting and domain for this blog. But I still can’t doing daily or weekly update. Yeah I know it. I am bored to the max.=p its because at first I have this blog, I usually have daily update, maybe so simple but I get more benefit from this. But now..T_____T I have no idea. Really.

Sequence Diagram dan Collaboration Diagram

cheuw — Wed, 16 Jun 2010 13:01:42 +0000

Diagram interaksi yaitu diagram yang menggambarkan suatu interaksi objek-objek dalam usecase. Nah diagram interaksi ini sendiri terdiri dari 2 diagram antara lain diagram sekuen (sequence diagram) dan juga diagram kolaborasi (collaboration diagram). Lalu diagram sekuen apa sii? Diagram sekuen itu menggambarkan perilaku objek yang ada di usecase dengan mendeskripsikan metode-metode yang dimiliki kelas.

Sedangkan diagram kolaborasi yaitu diagram yang mengelompokkan pesan pada kumpulan diagram sekuen menjadi sebuah diagram. Dalam diagram tersebut terdapat method yang dijalankan antara objek yang satu dan objek lainnya.Di diagram kolaborasi ini, objek harus melakukan sinkronisasi pesan dengan serangkaian pesan-pesan lainnya.

Class Diagram dan Objek Diagram

cheuw — Wed, 09 Jun 2010 01:05:06 +0000

Untuk mendesain sebuah sistem informasi yang sederhana, dibutuhkan juga class diagram dan objek diagram. Kenapa? karena diagram tersebut menggambarkan kelas-kelas yang akan digunakan pada nantinya dalam sistem informasi. Nah sekaran apa sih class diagram dan objek diagram itu sendiri?

Class diagram merupakan suatu diagram yang menggambarkan/memvisualisasikan struktur sistem dari kelas-kelas serta hubungannya. Class diagram ini juga menampilkan interaksi dalam kelas-kelas tersebut, atribut apa yang dimiliki atau operasi/metode apa yang dimiliki kelas itu,bagaimana jenis-jenis objek dalam sistem,batasan-batasan yang ada dalam hubungan objek itu,dsb.

Sedangkan yang dimaksud objek diagram adalah diagram yang memberikan gambaran struktur model sebuah sistem, dalam kurun waktu tertentu. Obyek diagram lebih konkrit daripada kelas diagram, dan sering digunakan untuk memberikan contoh-contoh, ataupun dalam menguji kasus untuk diagram kelas. Diagram Objek ini berfokus pada atribut, objek dan hubungan/korelasi antar objek.

Contoh dari tugas besar untuk class diagram dan objek diagram pada sistem informasi hotel :

Membuat FTP Server di Ubuntu

cheuw — Sun, 30 May 2010 12:17:01 +0000

File Transfer Protocol (FTP) adalah protokol TCP untuk mengupload dan mendownload file antar komputer. FTP ini bentuknya sebagai klien/server. Komponen server nya disebut FTP Daemon, yang secara terus menerus menerima permintaan FTP dari remote clients. Nah untuk membuat FTP Server itu sendiri terdiri dari beberapa langkah-langkah. Dibawah ini merupakan tahapan proses pembuatan FTP Server di Ubuntu.

1. Menginstall vsftpd yang merupakan FTP Daemon yang tersedia diubuntu, untuk menginstall vsdtpd ini bisa dijalankan dengan menjalankan perintah :
sudo apt-get install vsftpd
2. Konfigurasi Anonymous FTP
Pada umumnya vsftpd dikonfigurasi hanya mengizinkan anonymous download. Jika kamu ingin mengubah lokasi default FTP directory, ubahlah user ftp home directory dengan cara :
sudo mkdir /srv/ftp sudo usermod -d /srv/ftp ftp
Setelah melakukan perubahan kemudian restart vsftpd nya
sudo /etc/init.d/vsftpd restart
Lalu copy file atau direktori yang diinginkan melalui anonymous FTP ke /srv/ftp

3. Konfigurasi FTP Autentikasi User
Mengkonfigurasi vsftpd untuk mengautentifikasi sistem user dan mengizinkan mereka mengeupload files, edit lah file /etc/vsftpd.conf
dengan cara mengetikkan perintah sudo nano /etc/vsftpd.conf
kemudian edit menjadi :

local_enable=YES
write_enable=YES

kemudian restart vsftpd dengan cara
sudo /etc/init.d/vsftpd restart

4. Mengamankan FTP
Ada banyak pilihan di /etc/vsftpd.conf untuk membantu membuat vsftpd menjadi lebih aman. Contohnya use dapar diberi batasan hak akses ke home direktori dengan cara uncommenting:
chroot_local_user=YES
dan sebagainya, jangan lupa setelah melakukan perubahan, restart kembali vsftpd nya.

Just Quick Update

cheuw — Wed, 26 May 2010 12:15:43 +0000

Ahh..It’s been a long time did not update this blog as you can see yourself, the last I wrote in April, not only that, it’s almost more than 3 months the productivity post declining .. I don’t know why. Not because I’m busy with my studies, nor because I didn’t have time, but because I’m being a mediocre performance, just read the information and keep abreast .. ^ ^ just kidding, in fact lately I just followed the K-pop wave, especially SNSD, so I used my time to watch, listen, discuss the k-pop idol. So in the end of this blog is becoming a victim .. LOL

Mianhae..=(
And for the future project, I want to make this blog “alive” again and make a new special blog .. for the last one, that’s still secret.. =p
