Tambahkan favicon.ico

Dengan cara yang hampir sama menambah logo, berikut adalah cara menambah favicon.ico. Buat gambar favicon.ico-nya dulu dengan ukuran 32 x 32 piksel atau 16 x 16 piksel. Bisa dibuat menggunakan pengolah gambar GIMP.

Lalu salin ke direktori (direktori sistem operasi) /var/lib/mediawiki/skins/common/images/favicon.ico

Tambahkan baris berikut pada berkas /etc/mediawiki/LocalSettings.php

$wgFavicon = "/wiki/skins/common/images/favicon.ico";

Grr Ganti Logo Mediawiki

Grr... akhirnya bisa juga. Setelah kutak-katik, akhirnya aku bisa juga ganti logo mediawiki. Sederhana harusnya. Cuma jadi rumit saat konsep path bercampur baur dengan konfigurasi dan direktori di sistem operasi

Berikut konfigurasi /etc/apache2/sites-available/wiki
# more /etc/apache2/sites-available/wiki

ServerAdmin za@design.paume.itb.ac.id
ServerName ***.****.itb.ac.id
DocumentRoot /var/lib/mediawiki

ErrorLog /var/log/apache2/error-wiki.log
LogLevel warn
CustomLog /var/log/apache2/access-wiki.log common

ServerSignature Off


Lalu petunjuk pencerahan saya dapat saat membaca cuplikan log
# vim /var/log/access-wiki.log
...
*** - - [24/Dec/2008:02:20:54 -0600] "GET /wiki/skins/monobook/bullet.gif HTTP/1.1" 304 -
*** - - [24/Dec/2008:02:20:54 -0600] "GET /wiki/skins/common/images/poweredby_mediawiki_88x31.png HTTP/1.1" 304 -
*** - - [24/Dec/2008:02:20:54 -0600] "GET /wiki/skins/monobook/user.gif HTTP/1.1" 304 -
...


Ternyata direktori /wiki masih diperlukan sebagai path untuk memanggil gambar. Logo baru yang ingin saya masukkan, saya salin ke (ini path sistem operasi) /var/lib/mediawiki/skins/common/images/logo.png

Lalu tambahkan baris berikut pada /etc/mediawiki/LocalSettings.php

...
$wgLogo = "/wiki/skins/common/images/logo.png"
...


Taraaa!!!!

Reset Password MySQL

Terlalu banyak password memang membingungkan. Saat diminta untuk memasukkan password lagi (untuk database, misalnya), maka seringnya saya akan lupa.

Untung menemukan tautan ini.

Belajar PostgreSQL

Ini tautan bagus.

Belajar Awk

Saya ingin mengambil angka hasil melakukan ping. Untuk itu saya perlu melakukan parsing dari hasil yang muncul.

Melakukan ping 5 kali
$ ping -c 5 localhost
64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.092 ms
64 bytes from localhost (127.0.0.1): icmp_seq=2 ttl=64 time=0.071 ms
64 bytes from localhost (127.0.0.1): icmp_seq=3 ttl=64 time=0.069 ms
64 bytes from localhost (127.0.0.1): icmp_seq=4 ttl=64 time=0.067 ms
64 bytes from localhost (127.0.0.1): icmp_seq=5 ttl=64 time=0.060 ms

Lalu saya ambil urutan (urutan ke-6) berikut response time (urutan ke-8)
$ ping -c 5 localhost | awk '{print $6 " " $8}'
of
icmp_seq=1 time=0.070
icmp_seq=2 time=0.089
icmp_seq=3 time=0.085
icmp_seq=4 time=0.064
icmp_seq=5 time=0.090


0% loss,

Dilanjutkan lagi, ambil angkanya saja
