SATA RAID Howto (Ubuntu Dapper 6.06)

Ubuntu

Ubuntu (and Debian) doesn’t have support for the SATA RAID (also called FakeRAID since some of the functionality is provided by software) controllers being shipped on recent motherboards (The only distros to support these currently are Gentoo and Fedora Core 5). The software to handle FakeRAID arrays in Linux is dmraid.

Dmraid is currently not integrated into the Debian installer or the Ubuntu Live-CD installer. Therefore, one cannot directly install Ubuntu onto such RAID arrays. Previously, one had to install Ubuntu on to a separate partition and then debootstrap Ubuntu. However the Dapper Live-CD can be used to easily install Ubuntu Dapper onto such RAID arrays

Local DNS Cache for Faster Browsing

A DNS server resolves domain names into IP addresses. So when you request “google.com” for example, the DNS server finds out the address for the domain, and sends your request the right way.

You can run a DNS cache on your computer. This will speed up the process of looking up domain names when browsing. The difference is about 30-60 ms for me. Multiply that difference by the number of websites you visit a day for an approximate estimate of the speed improvement. Of course, all this would be worth it if it weren’t for the fact that setting this up is way too easy.

Sulit Dimengerti…!!!

Kala waktu yang bergulir
Angin bersemilir menari diatas kalbu
Jiwa terasa agung menalaah mutira terindah
terkadang sulit ku mengerti…..
inikah rasanya cinta
tersanjung bila dipuji….

Kala bisik megusik tiada kah aku tahu cinta itu
Hadir tanpa aku sadar….
pergi tanpa diharapkan

kaya hatiku…..
membelenggu sukma…
Aku tak tahu makna itu
Tolong pahami aku

Ketika sayang mengalir bagai air…..
Diriku adalah setetes embun yang diharpkan memberi cinta

Ketika bimbang menggoda…
Memilih kebersamaan tanpa sayang
Memilih cinta tanpa kepercayaan

Sulit mengerti cinta
Mengerti hidup yang menapak indah
Mengerti langkah pijar yang menemani suka
Namun cinta tak pernah ada arah….
dia mengalir dan terus mengalir

izinkan aku mengerti langkah pijarmu
dan menemai waktu yang kian usang
Derai sukma hanya sembunyi dalam kalbu
Biar aku mengaduh dalam hati ku saja…

Cinta…..Sulit ….. Dimengerti…!!!
