Quit smoke on 1 May 2009

I want to quit smoke.
Smoke is not cool.
Many girls hate smoker.
There are no conjunction between rocker and smoker.
There are no conjunction between hacker and smoker.
I'm cool with or without smoke.

KNAC Webmail

Okay, after sending many emails both to KNAC and it's mail service hosting Everyone.net, my webmail account is now reactivated after several days in suspended state. Thanks for your co-operation i really appreciate that although they (Everyone.net) never answer my mail.

Defensive Programming

I'm now reading "Defensive Programming for Red Hat Enterprise Linux" by Ulrich Drepper, of course not only for RHEL but for every Linux system and programmer who think security is a big issue.

Suspended webmail

Oh.. fucking good... my webmail account at KNAC.COM has been suspended, WTF? i didn't break any rule, spread spam or put forbidden stuff. What the hell? i already use KNAC.COM webmail since 2003, i put many docs there, many mailing lists, and contacts and identify informations. I got fucked.

Fedora: Costumization

You may know that Fedora was targeted for desktop user, therefore many desktop applications such as X Server, Window Manager, Desktop Environment, Network Application (browser or messenger), Multimedia and many more have been already included. For those who want to use Fedora for server, router or even a small system that use only console based application you may follow this customization.

You can get a list of installed applications or application's group and remove that you don't need, for individual application you can try with rpm:

#rpm -qa | more

This will show you a list of applications installed on your system, to remove a application named i-dont-need-you:

#yum remove i-dont-need-you

Just for sure, you don't want to remove a application which has dependency with your desired application right? so be carefull.

Then For group of applications:

#yum grouplist

Will list some series of group used by Fedora, to remove a group of application let say 'Web Development' (coz you are not PHP or AJAX ninja ;p):

#yum groupremove 'Web Development'

Before removing a application that you don't know what is and what for, use:

#yum info 'application_name' or #yum groupinfo 'group_name'

Enjoy!

Debian USB Installation

Have you try new Debian 5.0 (Lenny)?, i'm using it in my another x86 PC. I got bored install with CD/DVD-ROM image, that means you must burn the image file and you will need a blank CD/DVD. Is there any other method? (who said that). Cool, Debian also support network and USB disk installation. 256MiB of USB disk's size is enough if you prefer netinstall image, 1GiB for CD image. So here i go:

1. Unmount first if the USB disk already mounted.
2. Create a MBR into the USB disk using mtools utility: install-mbr:

#install-mbr /dev/usb_disk

1. Prepare your USB disk, create a FAT16 filesystem:

#mkdosfs -n lenny -F 16 -I /dev/usb_disk

2. Mount the USB disk.
3. Install syslinux.

#syslinux /dev/usb_disk

4. Create a simple syslinux.cfg:

default vmlinuz
append initrd=initrd.gz

5. Transfer all installation image (kernel, initrd) and a CD or netinstall ISO image:

#cp vmlinuz initrd.gz debian-lenny.iso /mnt/usb_disk

If all in set, the USB disk is now ready! Happy Debian.

NOTE: This maybe works in Ubuntu distribution since Ubuntu based on Debian... We should try ;p

FreeBSD

Yeah, today i installed new FreeBSD 7.1 release. Have some difficulties but resolved them by reading FreeBSD's handbook. So, here my notes regarding FreeBSD:

- Put it's rc.files in /etc/rc.d
- Put system wide configuration in /etc/rc.conf (networking, service, etc.)
- Use pkg_add to install package from it's repository.

and... what you should know about FreeBSD:

- It's a preemptive multitasking operating system
- Can run in 32 or 64 bit platforms (x86, AMD64, Alpha, Itanium, UltraSPARC)
- SMP (Symmetric Multi Processor) support
- Can run X Server: thus we are able to use GNOME or KDE for desktop
- Offer memory protection for user-space application (don't touch me)
- Great TCP/IP support
- Binary compability: you may run a program which compiled in Linux, SVR4, SCO, BSDI, or NetBSD
- C codes ;p and many more

Did someone said: "...it's about like we see in Linux kernel?" indeed.

I'm now installing GNOME 2 using pkg_add, i will update this note when i was finished.

Kernel: Compiling a simple module

Here a simple for beginner to compile their first kernel module:

1. Create a simple Makefile:

obj-m += mymodule.o

2. Compile and link the module, notice you should replace your kernel source:

$make -C /usr/src/linux SUBDIRS=$PWD modules

3. Use insmod or rmmod to insert and remove your module into kernel space.
4. Watch your module log message in the kernel ring buffer via dmesg or tailing /var/log/messages only if you did some debugging info.

Update on 09/09/2011

Another method is to create complete Makefile script for example

KERNEL_DIR = /usr/src/linux
SOURCE_DIR = /project/cpu

obj-m += cpu.o

all:
    make -C ${KERNEL_DIR} SUBDIRS=${SOURCE_DIR} modules

clean:
    make -C ${KERNEL_DIR} SUBDIRS=${SOURCE_DIR} clean

Have many fun...

Linux Kernel Project

What you need to care in linux kernel development

* The kernel does not have access to the C library.
* The kernel is coded in GNU C.
* The kernel lacks memory protection like user-space.
* The kernel cannot easily use floating point.
* The kernel has a small fixed-size stack.
* Because the kernel has asynchronous interrupts, is preemptive, and supports SMP, synchronization and concurrency are major concerns within the kernel.
* Portability is important.

Not vote to any party

This supposed to be posted in 9th April this year as my country's party election, i have no idea why i should vote one of them, i confused about who they are, what bring them to being crazy in government position and what for? there are too many party - 44 parties with 44 bullshits -. I'm not encourage anyone in order tvote, just vote what you are believe in, i'm not satisfy with one of them, so i don't have a reason to vote. Did someone said "You don't try too hard for knowing them" ?, indeed, bacause i think they are useless. Why i should vote for something i don't believe in?

Zakk Wylde

This morning in Zakk Wylde's official website. I'm hearing "I don't wanna stop" shit, this song kicked my lazy ass... is this song was singed by the Dark Lord? Ozzy Osbourne? i think so. Zakk has a incredible guitar power, GOD's shake vibrato, and metal style. His Gibson Les Paul looks so cruel! That's the main reason why i love Rock!

Fedora: Non-free packages

Have enjoying using the latest Fedora 10 now i'm thinking about multimedia contents, you may know the Fedora Project aims to provide only "free-as-freedom" packages, therefore any propriety codec will not be included. Rpmfusion a RPM based packages repository provide non-free gstreamer plugin to play propriety codec (gstreamer-plugins-bad). Here are the steps:

1. Goto Rpmfusion, download and install it's non-free repository package, for example: #rpm -Uvh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
2. Fetch it using yum #yum update
3. Search for gstreamer-plugins-bad and install it. #yum install gstreamer-plugins-bad

Try the codecs using gstreamer based player (eg. Totem), if the movie/song was not played and Totem told you such as "plugin search", just follow the wizard.

Upgrade to Fedora 10

This night i updated my Fedora box to version 10 (previously version 8), i use Live-CD installer, burn the image into a CD. Problem, the CD was corrupted, i got I/O request error when booting. I switch to USB install. Assume we are login as root, and the USB stick's device is /dev/sdb. Here are my steps:

#mkdofs -F 16 -n Fedora10 /dev/sdb
#yum install livecd-tools
#livecd-iso-to-disk /path/to/live-cd-image.iso /dev/sdb

Then boot with the USB to start installation, the installation process is pretty fast. I don't know what new features that Fedora 10 comes with but i should try a shiny new distro too :p.

Building RTAI Linux

Today i build RTAI Linux based system on Intel Celeron(M) processor @ 1Ghz, it is a single board computer for use in TCT (Toll Collecting Terminal). I use RTAI version 3.6 with Kernel 2.6.23 on Debian Lenny. Since Debian Lenny comes with GNU C Compiler version 4.3, the Kernel and RTAI was failed to build - I know, the Kernel actually forbid to use except GCC version 4.1 -. Then i move to Fedora 8 with GCC version 4.1. Here my steps:

1. Patch the current Kernel.
#patch -p1 < /tmp/rtai/base/arch/i386/patches/hal-2.6.23-rtai-patches-x.x-x.patch

2. Customizing and compile the current Kernel.
#cd /tmp/kernel-2.6.23
#make menuconfig
#make bzImage

3. Compile RTAI (set Kernel and installation directory, in this sample i use /rtai for the installation directory).
#cd /tmp/rtai
#make menuconfig
#make
#make install
#tar cjvf rtai-tct.tar.bz2 /rtai

4. Copy the compiled Kernel and RTAI into the host machine.
5. Run test suite.

to be continued...

Moving into Git

Matthias Classen from gtk-devel-list on Gnome mailing list announce:

Last week, I said that I'd like to get this done by the end of March, which is almost upon us now.

Therefore, I'd like to ask everybody to hold off with committing to svn. While we are not quite ready to start the migration yet, it will begin sometime later today. So to avoid duplicate work, it would be best to wait with further commits to glib and gtk+ until the migration is completed. I'll send another email with checkout information, etc, when the conversion is done.

See you all on the other side !

Matthias

Okay, so we are preparing into Git: a versioning system which introduced first by Mr. Linus Torvalds for the Linux Kernel Project to replace SVN.
