[Ubuntu] Mempercepat Ubuntu

Optimize ubuntu boot sequence by profiling it

While you are in grub menu highlight your preferred kernel version and press "e".

Highlight the line beginning with kernel and press "e" again. Press End key in order to goto end of that line.

Add a word "profile" without quotes to that line and press Enter.

Now press "b" to continue booting.

This one time special boot may take more time than ordinary boot. But during this boot ubuntu monitors file usage and preloads those files during subsequent boots.

prelink

Any executable that makes heavy use of shared libraries can benefit from prelinking. Prelinking resolves addresses of shared libraries in advance this reduces number of relocations.

Prelink is also useful in the context of security since we can tell prelink to make libraries load at random addresses until next run of prelink. This is useful since libraries won’t load at fixed addresses on every system.

You can install prelink by issuing following command.

[Ubuntu App] Pysdm : Otomatis Mount Partisi

Saya memiliki satu harddisk (sda) dan beberapa partisi yakni sda2, sda3, sda5, sda6.

sda2 dan sda6 merupakan partisi linux, sda5 merupakan partisi swap, dan sda3 merupakan partisi ntfs.

saya ingin partisi sda2, sda3, dan sda6 untuk menyimpan data, dan setiap kali komputer saya jalankan, ketiga partisi tersebut secara otomatis ter mount, sehingga ketika saya memainkan musik yang ada di sda6, bisa langsung saya mainkan menggunakan audacious.

Untuk mount otomatis sebuah partisi biasanya di arahkan untuk menggunakan command line yang merepotkan, namun dengan pysdm, kita cukup klik mount atau unmount untuk mengaktifkan otomatis mounting partisi tersebut.

Cara installasi, buka terminal ketik :

[Ubuntu APP] Aria2 : Howto Use

Basic Usage

Download a file

aria2c http://host/image.iso

Note: As of 1.10.0, aria2 uses 1 connection per host in each download. You can change this using –max-connection-per-server or its short form -x option.

To download a file using 2 connections from single host:

aria2c -x2 http://host/image.iso

Note: To stop a download, press Ctrl-C. You can resume the transfer by running aria2c with the same arguments at the same directory. You can change URIs as long as they are pointing to the same file.

Download a file using 2 connections

aria2c -s2 http://host/image.iso http://mirror1/image.iso http://mirror2/image.iso

Note: If you specify URIs more than the value of -s option, for this example, 2, first 2 URIs are used and 3rd URI is used for backup, which means if one of first 2 URIs are failed then 3rd is kicked in.

[JAVA APP] BBed : PHPBB Offline Editor

Kadangkala, kita ingin posting di forum dengan tulisan yg agak panjang, ya semacam tutorial.

[Pemula] CL Program

Pemprograman di AS/400 ada beberapa yang ingin saya kenalkan untuk pertama kali yakni CLP, Command Line Programming, secara garis besar untuk CLP ini seperti layaknya membuat file batch di windows, yakni membuat satu buah file yang didalamnya berisi beberapa perintah (command) yang telah ada di AS/400 itu sendiri seperti chgusrprf, wrksplfa, chgsplfa, dll sebelum memulai membuat programnya, tentu harus masuk ke editor nya dulu (notepad kali ya kalo di windows). caranya

1. di command line ketikkan STRPDM untuk menjalankan Programming Development Manager.
2. disana akan ada beberapa option, saya lebih sering option 3 untuk langsung masuk ke library dan source file yang sudah saya buat, jadi ketika memilih option 3 masukkan kan source file dan librarynya. kalau belum ada source filenya, kita buat dulu dengan command CRTSRCPF lalu tekan F4 ingat jangan enter, lalu masukkan nama file yang diinginkan umumnya untuk CL namanya QCLSRC, dimulai dengan Q dan diakhirin dengan SRC.
3. ketika sudah berada di file source, create member dengan menekan F6.
4. masukkan nama yang anda inginkan dan tipenya yakni CLP, lalu enter.
5. anda saat ini akan ada di editor SEU, nah pemprograman dilakukan disini.
6. Jika sudah selesai, tekan F3, untuk keluar dan save program anda.
7. Compile program anda dengan memberikan option 14 pada program anda.
8. jalankan program andan dengan command call LIBRARY/PROGRAM_ANDA

[UBUNTU]Djl : Install Lebih Dari 100 games Dengan 1 Command

Djl is an open-source (GPL licensed) game manager written in Python 2.5 for the GNU/Linux Operating Systems. It is inspired by Valve’s Steam software for Windows.

Djl makes it possible (via a repository) to download, install and remove a reasonable number of games placed into a distrobution independent subdirectory (but without dealing with any dependencies). It can also execute ,desktop shortcuts located in another directory.

Actually Djl have more that 105 game in his repository, games like Alien Arena, Blood Frontier……..,

see the complete list of games.

To install Djl download the tar file from this link :

http://en.djl-linux.org/?q=node/19

then download the latest version djl-1.2.14.tar.gz

Now before to install the game be sure that these dependencies are installed :

python

python-qt4

If the dependencies are not installed then use :

For fedora/redhat/centos, under root :

yum install python python-qt4

For Ubuntu :

sudo apt-get install python python-qt4

Now after the dependecies are installed we will extract the downloaded file djl-1.2.14.tar.gz

tar -zxvf  djl-1.2.14.tar.gz

Go to the folder where you extracted the tar file :

cd   djl

And launch the installation using this command :

sh djl.sh

Please indicate the install directory and location of your browser

the script will contact the Linux games servers and download some games for you , plus their

plugins and chat between gamers.

Now once the games are installed, they can be launched from main window, which not only

contains games that are installed from the repository, but also shortcuts as .desktop files.

Enjoy and if you like it, don`t forget to digg it
