WordPress update without FTP

March 14th, 2013

When I want to install upgrade / theme into wordpress, some of my server request me to input FTP connection setting, the others don’t. The problem is, my server don’t have a FTP account.

I’m trying to figure out, what’s the difference in setting, but i cannot find any. Luckily today i found a way to force wordpress NOT using the FTP method.

You just need to edit the wp-config.php. Add this line

define('FS_METHOD' , 'direct');

Coloring Mac Terminal

September 14th, 2010

By default Mac OS X’s Terminal application uses the Bash shell (Bourne Again SHell) but doesn’t have directory and file color highlighting enabled to indicate resource types and permissions setting

Enabling directory and file color highlighting requires that you open (or create) ~/.bash_profile in your favourite text editor, add these contents:

export CLICOLOR=1
export LSCOLORS=ExFxCxDxBxegedabagacad

… save the file and open a new Terminal window (shell session). Any variant of the “ls” command:

ls -l
ls -la
ls -lah

… will then display its output in color.

More details on the LSCOLORS variable can be found by looking at the man page for “ls“:

man ls
LSCOLORS needs 11 sets of letters indicating foreground and background colors:

symbolic link
block special
character special
executable with setuid bit set
executable with setgid bit set
directory writable to others, with sticky bit
directory writable to others, without sticky bit

The possible letters to use are:

a  black
b  red
c  green
d  brown
e  blue
f  magenta
c  cyan
h  light grey
A  block black, usually shows up as dark grey
B  bold red
C  bold green
D  bold brown, usually shows up as yellow
E  bold blue
F  bold magenta
G  bold cyan
H  bold light grey; looks like bright white
x  default foreground or background

By referencing these values, the LSCOLORS variable setting mentioned above translates to:

Bold blue with default background for directories, bold magenta with default background for symbolic links, bold green with default background for sockets, etc.

FTP Sync

April 14th, 2010

I use rsync a lot for sync between my Local and Remote Backup Server, rsync is doing very great job in term of speed and stability. But in certain cases, my client is not using ssh enabled account. So i forced to use an FTP sync, which is very slow. Sure you can use usual FTP Client like Filezilla, etc. But I doesn’t have a good build in sync system.

So I start googling and find 1 solution using LFTP. This program is already installed on standard Ubuntu installation, so you can use it immediately.

This is a sample file how to do a sync

lftp -c "set ftp:list-options -a;
open ftp://$USER:$PASS@$HOST; 
lcd $LCD;
cd $RCD;
mirror --reverse \
       --delete \
       --verbose \
       --exclude-glob config/ \
       --exclude-glob .htaccess \
       --exclude-glob index.php"

Finally in the section where it writes –exclude-glob, you write file that you should exclude in sync process. You can write directory name with / (slash) or filename, or event support a wildcard (* / ?).

Hope it helps

How to use ‘find’ in file

January 7th, 2010

Linux has many usefull command.

I always use this command to find a single file

find . | grep filename

But it’s not a really good implementation to how to use the syntax. For search file name, use this command instead.

find -name filename
find -name "you can event use a wildcard *"

For directory you can write like this

find -type d

For find only file

find -type f

Together joined will be

find -type f -name "rick*"

And the most useful syntax, you can run a command on every file it found. Here’s how to delete every jpg it found.

find -type f -name "*.jpg" -exec rm {} \;

Or upgrade all bzr in every directory

find -type d -maxdepth 1 -exec bzr update {} \;

Hope it helps

Tips buat atasin LIMIT di subquery

August 4th, 2009

Bagi yang sering otak-atik MySQL dan bermain-main dengan subquery pasti pernah ketemu dengan pesan error ini dech.

This version of MySQL doesn’t yet support ‘LIMIT & IN/ALL/ANY/SOME subquery’

Tadi kebetulan ada temen saya yang tanya. Eh Gimana sih keluarin data 5 tertinggi dari 50 data yang gue random? Pertama gue jawab-in bahwa query nya seperti ini


Terus gue bilang, bahwa “saat ini versi MySQL belom ada yang bisa begitu”. Terus setelah dia cari2, rupanya bisa diakal2in seperti ini :


Semoga membantu.

Blackberry Application Launcher

June 24th, 2009

Pernah penasaran begimana caranya bikin launcer seperti Punya website mobile dan pengen bikin launcher yang serupa tapi engga tahu cara bikinnya? Saya juga ^^

Saya baru aja mencoba bikin applikasi launcher seperti itu, yang rupanya engga sulit2 amat. Tutorial nya bisa banyak ditemukan dimana2. Code nya juga sebenernya simple sekali, hanya buka website tersebut, dan close program tersebut. Makanya disebut application launcher.

Ngapain pake launcher kalo bisa cuma pake bookmark?
1. Engga semua orang punya knowledge untuk menggunakan browser dengan semestinya.
2. Simplicity
3. Mengurangi 1 step click menuju bookmark

Semua proses pembuatannya sebenernya simple. Tapi ada satu masalah. Applikasi blackberry sebelum di launch mengharuskan developer untuk “menandatangani” applikasi tersebut. Gunanya supaya RIM bisa tracking code mana saja yang ada di pasar dan dikembangkan. Untuk bisa menandatangani applikasi tersebut dibutuhkan $20 tambahan.

Nah khan cape kalo cuma mao bikin satu launcher simple aja tapi sampe harus bayar biaya segitu ^^, nah kemaren itu baru aja gue register 1 key.

Gue menawarkan service untuk membuatkan anda application launcher hanya dengan 20Rb rupiah. Itung kita bagi2 license key nya supaya sama2 senang :P

Anda cukup mempersiapkan
1. URL website anda
2. Icon berupa PNG berukuran 80 x 80 pixel
3. Uang Rp 20.000

Jika anda tertarik silahkan tinggalkan informasi untuk menghubungi anda di comment.

Untuk contoh silahkan download launcher sample di

Samba on Ubuntu

January 5th, 2009

Ada masalah yang timbul pada saat kita mount smbfs ke suatu direktori. Masalah yang akan timbul adalah symbolic link tidak bisa diakses seperti layaknya bila di akses dari Windows. Jika kita membuat symlink ke folder lain (contoh: /opt/lampp/htdocs dan diarahkan ke /home/admin/www/), jika folder admin itu di mount ke Windows, makan pada saat kita klik ‘www’, akan dibuka tanpa masalah, Windows akan mengira symlink itu adalah suatu direktori, dan samba akan otomatis mengeluarkan isi direktori tersebut, ini bukanlah bug tetapi fitur yang sangat baik.

Jika anda mencoba mount folder tersebut dari ubuntu dan klik folder www tersebut, yang terjadi adalah, symlink tetaplah sebuah symlink. Anda akan dibawa ke folder /opt/lampp/htdocs di local anda. Cara pemecahannya adalah:

Tambahkan ini di bagian [globals]

follow symlinks = yes
wide symlinks = yes
unix extensions = no
