Speed Up Firefox

There are some more settings in Firefox that can be changed to increase the speed of loading web pages.

If your using Firefox on a broadband connection...this will speed up your browsing significantly.

1. Type "about:config" into the address bar and hit return. Scroll down and look for the following entries(open a new window to do this ) :
network.http.pipelining
network.http.proxy.pipelining
network.http.pipelining.maxrequests

Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.

2. Alter the entries as follows: (double click the entry to change)
Set "network.http.pipelining" to "true"
Set "network.http.proxy.pipelining" to "true"
Set "network.http.pipelining.maxrequests" to some number like 30. This means it will make 30 requests at once.

3. Lastly right-click anywhere and select New-> Integer. Name it "nglayout.initialpaint.delay " and set its value to "0". This value is the amount of time the browser waits before it acts on information it receives.

Manajemen iPod dengan Amarok (PCLOS)

First the problem... This is a Windows iPod with a vfat filesystem. As received, the iPod would automount and I could see it in Konqueror and seemingly add music to it using Amarok.

The problem was when unplugged the iPod didn't think it had any songs. Searching on the web led me to this procedure.

Connect your iPod with the usb cable. Type the following as root in a terminal:
lsusb -v | grep -i Serial

Among other output you will get a line looking like 000A1234567891231.

Copy this line.

Navigate to your_iPod/iPod_Control/Device folder and open the file called SysInfo. Paste the line to the file but append FirewireGuid: so that it finally looks like
"FirewireGuid: 000A1234567891231"

Save and exit.

This allowed me to send and remove songs, and album art with the iPod. The next issue is with eject. The web is full of dire warnings about ejecting your iPod before removing it for fear of corrupting the filestructure. For me, Kde was requiring root privileges to eject the device. This was easily done from konsole but I wanted to use the configurable disconnect button in Amarok. This is what worked for me. As root using kwrite I edited my /etc/sudoers file to include this line "ALL NOPASSWD: /usr/bin/eject /dev/sdb"

This allows anyone to eject /dev/sdb without a password. One would have to modify the above command to reflect where their device is mounted.

So, the config of my disconnect button in Amarok is "sudo eject /dev/sdb"
Hopefully, this will help someone get their iPod working with Amarok in PCLinuxOS.

Edit: Since I posted this I have been cautioned that if one had several USB devices and plugged and unplugged them in a changing order my eject command might be not be specific to the iPod only. I've been doing more testing and though I've been told removable media devices do not use /etc/fstab for instructions this works for me.

I include this line in /etc/fstab:
"/dev/sdb /media/ipod vfat rw,user,noauto 0 0"

I also changed my line in /etc/sudoers to:
"ALL ALL= NOPASSWD: /usr/bin/eject /media/ipod"

And finally, as you might have guessed I changed my disconnect button command to:
"sudo eject /media/ipod"

Testing with a USB stick and the iPod both plugged in shows this command to eject the iPod (no password) and the USB stick is still available.

Can I transfer my album art or videos?
Album art works for me. I think you need to have it in your Amarok collection before you transfer to your iPod. In your collection, drill to the song. There will be an icon that looks like a jewel case. Right click and choose get album art. Pick the one you like then transfer that song to your iPod, the art will come along.

If you have songs with no art you may have to delete the songs from your iPod, get the art, then transfer it back to the the iPod. I've been able to get video on and off the iPod like this.

First get gtkpod, ffmpeg, and winff from Synaptic.
Take some video from whatever source: if you're ambitious you could rip it from a DVD with DVD::rip

Point winff at it as the source. Choose one of the iPod choices in the 'format to convert to' drop down box. Let it do it's magic, then use gtkpod to send it to the iPod. One could use gtkpod for all iPod management, but I prefer the Amarok interface. Unfortunately, Amarok
doesn't seem to be able to transfer video to the iPod. Have Fun!

SMART : Package Manager alternatif (PCLinuxOS)

Official Homepage dari SMART adalah http://labix.org/smart, disini dijelaskan SMART adalah "
"The Smart Package Manager project has the ambitious objective of creating smart and portable algorithms for solving adequately the problem of managing software upgrading and installation. This tool works in all major distributions, and will bring notable advantages over native tools currently in use (APT, APT-RPM, YUM, URPMI, etc).

Notice that this project is not a magical bridge between every distribution on the planet. Instead, this is a software offering better package management for these distributions, even when working with their own packages. Using multiple package managers at the same time (like rpm and dpkg) is possible, even though not the software goal at this moment."

SMART memiliki beberapa keunikan, diantaranya :
- Support of RPM, DPKG, and Slackware packages- Thorough dependency check (even of packages not installed but available in the repository)
- Choice of suitable packages of different sources (if available)
- High speed parallel download of packages
- Locking of selected applications
- System repair function
- GUI and command line

Instalasi SMART
---------------
Install smart-suite, bisa menggunakan synaptic (GUI), atau apt-get (Terminal) dan memerlukan beberapa dependencies (ketergantungan dengan file lain).

apt-get update && apt-get install smart-suite

sebuah opsi aplikasi yang direkomendasikan adalah PCLinuxOS-SMART-ServiceMenu. Ini adalah salah satu dari sekian banyak program yang disediakan oleh pengguna

PCLOS di Jerman (user:Maik3531) dalam PCLinuxOS repository-nya. Keunggulan aplikasi ini adalah kemudahan menggunakan SMART dengan service menu-nya, dan

tersedia penjelasan tambahan di bawahnya. Kita bisa menambahkan repository Maik3531 ke sistem kita dengan menambahkan baris di /etc/apt/sources.list

rpm http://maik3531.de pclos2007/RPM testing

setelah menambahkan baris diatas, lakukan instalasi :

apt-get update && apt-get install PCLinuxOS-SMART-ServiceMenu

perintah diatas akan secara otomatis memilih dan menginstall aplikasi (dependencies) yang dibutuhkan.


selanjutnya untuk konfigurasi dan pemakaian bisa dilihat di : PCLOS Magazine edisi April 2008


Please note that this contains the “testing” component and you may choose to delete this entry as it
provides packages which are being tested by developers

and as such, not suitable in a stable production system.

Good Luck!!!

Repositories PCLinuxOS di server Kambing

PCLOS2007 menggunakan konsep repository seperti ubuntu. Selain itu PCLOS2007 punya apt-get, repository, dan juga synaptic. Jadi kita tidak kesulitan untuk menambah-nambah applikasi selain applikasi yang sudah ada.

Untuk Repositories Lokal bisa melalui FOSS-ID atau Kambing.ui.edu. Berikut langkah-langkah untuk menambah repositories di PCLOS2007 (http://kambing.ui.edu/pclinuxos/apt/pclinuxos/2007/):

Pertama
Edit aja link diatas sehingga hasilnya seperti dibawah ini;
rpm http://kambing.ui.edu/pclinuxos/apt/ pclinuxos/2007 main extra nofree kde

Kedua
Simpan baris tersebut di /etc/apt/sources.list (baris paling bawah ajah). Dan alamat repo yg tidak dipake kasih tanda pagar.

Ketiga
Hasil ahir, file sources.list isinya sbb (disamping text lain yg sudah 'dipagari');
rpm http://kambing.ui.edu/pclinuxos/apt/ pclinuxos/2007 main extra nofree kde

Keempat
update repos. Codenya;
apt-get update

Udah. 'Prosesi' penggantian alamat repo sudah selesai. Sekarang kita sudah bisa install program baru yg ada di repo tsb. Boleh menggunakan apt-get maupun synaptic. Dibawah Ini contoh Install program lewat apt-get;

[root@lapie apt]# apt-get install inkscape
Reading Package Lists... Done

Solusi : Lupa password Root? (PCLinuxOS)

Peringatan : ini adalah cara yang cukup berbahaya dan dapat merusak instalasi Linux anda, gunakan bila anda terpaksa saja, dan ingat jika salah melakukan perbaikan maka sistem akan rusak dan dapat berpengaruh terhadap data anda. Jika anda ragu, anda tidak sendiri, masih ada Linuxers diluar sana yang siap membantu. Silahkan baca menu bantu (HELP) dengan teliti sebelum melakukan perbaikan.

Apa yang akan lakukan jika lupa password root anda? Langkah paling radikal adalah install ulang :), tapi ada koq beberapa cara yang bisa anda lakukan tanpa harus install ulang, yaitu :
- dengan menggunakan LiveCD
- dengan menggunakan GRUB
- dengan melakukan booting single user mode dari Lilo


Berikut adalah cara termudah yaitu menggunakan LiveCD (PCLinuxOS) :

- Boot komputer dengan menggunakan LiveCD
- Lakukan mount pada direktori / (root) ----> mount sebagai orig_root
- Buka terminal dan ketik : cd /orig_root/etc
- Gunakanlah root login (pada LiveCD PclinuxOS password root adalah root)
- Edit file shadow (misalkan editor yang dipakai nano)
- Ketik : nano shadow
- Akan muncul beberapa baris text yang mirip seperti ini :
root:$1$8NFmV6tr$rT.INHxDBWn1VvU5gjGzi/:12209:0:99999:7:-1:-1:1074970543
bin:*:12187:0:99999:7:::
daemon:*:12187:0:99999:7:::
adm:*:12187:0:99999:7:::
- Perhatikan baris ini :
root:$1$8NFmV6tr$rT.INHxDBWn1VvU5gjGzi/:12209:0:99999:7:-1:-1:1074970543
- Dalam contoh ini, password yang terenkripsi adalah :
$1$8NFmV6tr$rT.INHxDBWn1VvU5gjGzi/
- Hapus password yang terenkripsi. INGAT jangan hapus “:” sebelum atau sesudah password. Setelah dihapus maka barisnya akan seperti ini :
root::12209:0:99999:7:-1:-1:1074970543
- Tekan ctrl + x untuk menyimpan file
- Reboot komputer tanpa menggunakan LiveCD
- Password root masih kosong, untuk menambahkan/membuat password root baru, buka terminal
- Ketik : passwd root
- Masukkan password root yang baru dan enter (akan muncul 2x pertanyaan, isikan dengan password yang sama)
- Sekarang komputer telah mempunyai password root yang baru :)

Untuk cara lainnya bisa dilihat di majalah PCLOS edisi Pebruari 2008.

Kalo sudah begini, saya malah mikir. Apa sekarang komputer saya aman dari tangan-tangan jahil yang mencoba menghapus dan mengganti password root saya????

Good luck !!
