Changing Time Zone in Slackware 13.1

2011-02-12T07:23:00.000-08:00

Travelling to different countries makes you experience different timezone, it can some hours ahead or after of your country timezone. Sometimes I experience this!, at the first time I was ignoring the time difference in my laptop. But this time not.

So below is the steps to change your timezone configuration in Slackware 13.1, you should do these steps as root.

Change time zone links in /etc: "/etc/localtime-copied-from" to your current timezone in /usr/share/zoneinfo/xxx/xxx (xxx is depends on your timezone area)
# ln -sf /usr/share/zoneinfo/xxx/xxx /etc/localtime-copied-from
Replace your "/etc/localtime" with your current "/etc/localtime-copied-from"
# cp -rf /usr/share/zoneinfo/xxx/xxx /etc/localtime
Update your time using ntp server (pool.ntp.org)

# ntpdate pool.ntp.org

# hwclock -w

Isn't it simple? In my opinion this's simple, but sometime we can't do the simplest thing.

Vim 7.3 Released

2010-08-17T22:14:00.000-07:00

On 16 August 2010, I had received an email from Vim google mailing list, this mail announce that Vim 7.3 was released to public finally. You can check below quote for release note by Bram Moolenaar.

Bad Evince Font in Slackware

2010-08-05T06:07:00.000-07:00

When I install evince on my Slackware, sometimes I encounter a strange problem which is the font is not display correctly or looks weird, as like the picture below:

You can see that there are fonts look too bold and inconvenient to read. After diving in google, I found that the problem comes from the Nimbus font in slackware package. To check and fix it you can follow instructions below:

Check fonts in pdf file

$ pdffonts file.pdf

/usr/share/fonts/Type1/n021004l.pfb
/usr/share/libwmf/fonts/n021004l.pfb

Download new n021004l.pfb

http://koji.fedoraproject.org/koji/buildinfo?buildID=138570

Extract the rpm package

# rpm2cpio urw-fonts-2.4-9.fc13.noarch.rpm | cpio -idmv

Copy fonts file and reboot

# cd usr/share/fonts/default/Type1
# cp n021004l.pfb /usr/share/fonts/Type1/n021004l.pfb
# reboot

After reboot then I check evince display, and the result is like below. There we can see that the font looks better and convenient than before.

I hope this tutorial is helpful.

Get apk from phone

2010-07-26T00:38:00.000-07:00

When I do flashing my Samsung Spica for the first time, I lost all of my application. It means I need to download it all again from market and costs my credit. Therefore I need to get my apk from phone, and backup it all to my PC.

After doing some tests and trials based on a clue from my friend. I finally find a way to backup all of applications by downloading all installed apk from the phone, and it's really simple.

Before going further, we need to install android SDK:

Download android sdk from here
Extract android sdk zip file to C:\
Add this "C:\android-sdk-windows\tools" to windows path in environment variable

And then to allow you accessing /data/app directory, you must have root permission therefore wee need to root the device. You can follow instructions in here to root your device here, but please be careful because it can bricks your device.

When you download applications from market, the system will store the apk files in /Data/app. Base on this information we can pull all of downloaded apk from phone to PC by using adb pull command.

adb pull /data/app "your destination directory"

And you can find all of your downloaded apk in "your destination directory".

PDCurses for MinGW32

2010-07-19T23:11:00.000-07:00

As I know MinGW doesn't come with graphic control library, it isn't like borland or turbo which brings conio.h. But you can use curses library for alternative. If you use Linux you can find ncurses library, but if you're windows user you can use PDcurses.

In this tutorial I'll explain how to install PDcurses for MinGW32 compiler in MS Windows. The first things you need are Installed MinGW32 compiler and PDcurses source. You can download MinGW from here and PDcurses from here.

Set up MinGW32

Install MinGW32, don't forget to install 'MinGW make' also (if you don't want to install MSys), in this case I'll install MinGW in C:\MinGW
Set environment path for MinGW bin directory

Go to control panel
Click System
Choose Advanced tab and click "Environment Variables" button
Add PATH variable for user, if you have one you can skip this
Select PATH variable and Edit
In "variable value" text box, add C:\MinGW\bin, and don't forget to use ';' (semicolon) as delimiter

If you didn't install MSys so you need to rename mingw32-make.exe become make.exe

   CD C:\MinGW\bin 
RENAME mingw32-make.exe make.exe

Install PDcurses

I assume you have downloaded PDCurses source successfully, in this case I have downloaded PDCurses-3.4.tar.gz
Unpack it by using winrar to C:\ and you will have C:\PDCurses-3.4 directory
Compile win32 PDcurses with DLL

  CD C:\PDCurses-3.4\win32  
make -f gccwin32.mak DLL=Y

Copy pdcurses.dll to C:\MinGW\bin

COPY pdcurses.dll C:\MinGW\bin

Copy pdcurses.a to be C:\MinGW\lib\libpdcurses.a

COPY pdcurses.a C:\MinGW\lib\libpdcurses.a

Copy pdcurses header file to C:\MinGW\lib\include

CD ..  
COPY *.h C:\MinGW\include

Test PDcurses

Create test.c

    #include <curses.h> int main()  
{   
    initscr();   
    printw("Hello World !!!\n");  
    refresh();   
    system("pause");   
    endwin();  
    return 0;  
}

Compile test.c and check if there is any error

gcc test.c -o test -lpdcurses

Test executable file. If you can see "hello world" it means everything goes well

test.exe

I hope this tutorial will be helpful for who need it.

Upgrade to Slackware 13.1

2010-06-09T23:59:00.000-07:00

Slackware 13.1 has been released on 24 May 2010. There are updates for some packages and kernel. Usually every Slackware released I will choose fresh install before use it, but now I won't choose that, I'll choose to upgrade.

Before going further. To keep my configuration files safe I need to backup my /etc folder. In this case I backup it by creating iso image of /etc and keep the owner and permission of those files. You can do below method for your important files aswell.
# mkisof -o ~/etc-backup.iso -R /etc

And then check it

# mount -t iso9660 -o loop=/dev/loop0 ~/etc-backup.iso /mnt/tmp
# ls -ll /mnt/tmp

Next step is based on UPGRADE.TXT instructions, you can find it in root directory of Slackware distribution package. There area some steps to do to Upgrade your slackaware:

Create packages folder
Switch to single user
Upgrade package utility and related tools
Upgrade glibc shared libraries
Upgrade packages and install new packages
Remove obsolete packages
Fix or install new configuration files
Finishing
Reboot

Create packages directory
You need to create directory which contains Slackware 13.1, you can download it one by one or download it in ISO format. In my case I download ISO file from one of this mirror and extract it into "Slackware packages" directory

# mount -t iso9660 -o loop=/dev/loop0 slackware-13.1-install-dvd.iso /mnt/tmp
# mkdir /slackware
# cp -rf /mnt/tmp/* /slackware/*

Basically I can use /mnt/tmp as "Slackware packages directory" but I prefer to copy it to another directory as my "Slackware packages" directory. It's only for safety and stability.

Switch to single user
I just do a simple command to switch into single user
# telinit 1

Upgrade package utility and related tools
Before going further we need to upgrade tools that related to packaging

# upgradepkg /slackware/a/pkgtools-*.tgz
# upgradepkg /slackware/a/tar-*.tgz
# installpkg /slackware/a/xz-*.tgz
# upgradepkg /slackware/a/findutils-*.txz

Upgrade glibc shared libraries
# upgradepkg /root/slackware/a/glibc-solibs-*.t?z

Upgrade packages and install new packages
If you want to upgrade and install all new packages, you can use command below
# upgradepkg --install-new /root/slackware/*/*.t?z
If you want to uprage and install new package based on package group you can use command below, just add and remove package group in looping.

#!/bin/sh
for dir in a ap d e f k kde l n t tcl x xap y ; do
    ( cd $dir ; upgradepkg --install-new *.t?z )
done

You can check the description of those package group below:

A : The base system.
AP : Various applications that do not require the X Window System.
D : Program development tools.
E : GNU Emacs.
F : FAQs, HOWTOs, and other miscellaneous documentation.
K : The source code for the Linux kernel.
KDE : The K Desktop Environment.
KDEI : Language support for the K Desktop Environment.
L : System libraries.
N : Networking programs.
T : teTeX document formatting system.
TCL : The Tool Command Language, Tk, TclX, and TkDesk.
X : The base X Window System.
XAP : X applications that are not part of a major desktop environment.
Y : Games (the BSD games collection, Sasteroids, Koules, and Lizards).

Remove obsolete packages
You can remove obsolete packages in Slackware 13.1 by using command below:

#removepkg bluez-libs bluez-utils cupsddk device-mapper epic4 gqview \
     kdelibs-experimental lbxproxy libgtkhtml liblbxutil libungif \
     libv4l loadlin mpg321 mplayerthumbs proxymngr xf86-input-citron \
     xf86-input-elographics xf86-input-fpit xf86-input-hyperpen \
     xf86-input-mutouch xf86-video-newport xf86-video-xgixp

Fix or Install New Configuration file
Upgrading means you will have new configuration files in etc, if you brave enough you can apply script below to apply it.

#!/bin/sh
cd /etc
find . -name "*.new" | while read configfile ; do
if [ ! "$configfile" = "./rc.d/rc.inet1.conf.new" \
    -a ! "$configfile" = "./rc.d/rc.local.new" \
    -a ! "$configfile" = "./group.new" \
    -a ! "$configfile" = "./passwd.new" \
    -a ! "$configfile" = "./shadow.new" ]; then
    cp -a $(echo $configfile | rev | cut -f 2- -d . | rev) \
        $(echo $configfile | rev | cut -f 2- -d . | rev).bak 2> /dev/null
    mv $configfile $(echo $configfile | rev | cut -f 2- -d . | rev)
fi
done

You should upgrade/merge your man.conf file and vimrc with these file:

/usr/man/man.conf.new
/usr/share/vim/vimrc.new

Reboot
# reboot

Finishing
If you've installed some packages that are not in Slackware default, you need to recheck it functionality, and if you find problem I think you need to recompile the software or it's dependency.

Slackware 13.1 has been released

2010-05-29T09:29:00.001-07:00

Yes, it's that time again! After many months of development and
careful testing, we are proud to announce the release of Slackware
version 13.1!

We are sure you'll enjoy the many improvements. We've done our best
to bring the latest technology to Slackware while still maintaining the
stability and security that you have come to expect. Slackware is well
known for its simplicity and the fact that we try to bring software to
you in the condition that the authors intended.

Slackware 13.1 brings many updates and enhancements, among which
you'll find two of the most advanced desktop environments available
today: Xfce 4.6.1, a fast and lightweight but visually appealing and
easy to use desktop environment, and KDE 4.4.3, a recent stable release
of the new 4.4.x series of the award-winning KDE desktop environment.
We continue to make use of HAL (Hardware Abstraction Layer) and udev,
which allow the system administrator to grant use of various hardware
devices according to users' group membership so that they will be able
to use items such as USB flash sticks, USB cameras that appear like USB
storage, portable hard drives, CD and DVD media, MP3 players, and more,
all without requiring sudo, the mount or umount command. Just plug and
play. Properly set up, Slackware's desktop should be suitable for any
level of Linux experience. New to the desktop framework are ConsoleKit
and PolicyKit. ConsoleKit handles "seats", things like dealing with
devices when switching from one user to another. PolicyKit is a system
for fine-grained access control, allowing a non-root user to run certain
tasks with elevated privilege, but more securely than if the entire task
were simply run as root.

Slackware uses the 2.6.33.4 kernel bringing you advanced performance
features such as journaling filesystems, SCSI and ATA RAID volume
support, SATA support, Software RAID, LVM (the Logical Volume Manager),
and encrypted filesystems. Kernel support for X DRI (the Direct
Rendering Interface) brings high-speed hardware accelerated 3D graphics
to Linux.

There are two kinds of kernels in Slackware. First there are the
huge kernels, which contain support for just about every driver in the
Linux kernel. These are primarily intended to be used for installation,
but there's no real reason that you couldn't continue to run them after
you have installed. The other type of kernel is the generic kernel, in
which nearly every driver is built as a module. To use a generic kernel
you'll need to build an initrd to load your filesystem module and
possibly your drive controller or other drivers needed at boot time,
configure LILO to load the initrd at boot, and reinstall LILO. See the
docs in /boot after installing for more information. Slackware's Linux
kernels come in both SMP and non-SMP types now. The SMP kernel supports
multiple processors, multi-core CPUs, HyperThreading, and about every
other optimization available. In our own testing this kernel has proven
to be fast, stable, and reliable. We recommend using the SMP kernel
even on single processor machines if it will run on them.

Here are some of the advanced features of Slackware 13.1:

- Runs the 2.6.33.4 version of the Linux kernel from ftp.kernel.org.
Also included is a kernel patched with Speakup to support speech
synthesizers providing access to Linux for the visually impaired
community. The 2.6.x kernel series has matured into a stable
kernel, and provides reliable performance for your desktop or
your production server.

- System binaries are linked with the GNU C Library, version 2.11.1.
This version of glibc also has excellent compatibility with
existing binaries.

- X11 based on the X.Org Foundation's modular X Window System.
There's been much activity in the X development world, and the
improvements in terms of performance and hardware support are
too numerous to mention them all here.

- Installs gcc-4.4.4 as the default C, C++, Objective-C,
Fortran-77/95, and Ada 95 compiler.

- Support for fully encrypted network connections with OpenSSL,
OpenSSH, OpenVPN, and GnuPG.

- Apache (httpd) 2.2.15 web server with Dynamic Shared Object
support, SSL, and PHP 5.2.13.

- PCMCIA, CardBus, USB, IEE1394 (FireWire) and ACPI support. This
makes Slackware a great operating system for your laptop.

- The udev dynamic device management system for Linux 2.6.x.
This locates and configures most hardware automatically as it
is added (or removed) from the system, and creates the access
nodes in /dev. It also loads the kernel modules required by
sound cards and other hardware at boot time.

- New development tools, including Perl 5.10.1, Python 2.6.4,
Ruby 1.9.1-p378, Subversion 1.6.11, git-1.7.1, mercurial-1.5.2,
graphical tools like Qt designer and KDevelop, and much more.

- Updated versions of the Slackware package management tools make it
easy to add, remove, upgrade, and make your own Slackware packages.
Package tracking makes it easy to upgrade from Slackware 13.0 to
Slackware 13.1 (see CHANGES_AND_HINTS.TXT). The slackpkg tool can
also help update from an older version of Slackware to a newer one,
and keep your Slackware system up to date. In addition, the
slacktrack utility (in extra/) will help you build and maintain
your own packages.

- Web browsers galore! Includes KDE's Konqueror 4.4.3,
SeaMonkey 2.0.4 (this is the replacement for the Mozilla
Suite), and the immensely popular Firefox 3.6.3, as well as
the Thunderbird 3.0.4 email and news client with advanced
junk mail filtering.

- The KDE Software Compilation 4.4.3, a complete desktop environment.
This includes the KOffice productivity suite, networking tools, GUI
development with KDevelop, multimedia tools (including the amazing
Amarok music player and K3B disc burning software), the Konqueror web
browser and file manager, dozens of games and utilities,
international language support, and more.

- A collection of GTK+ based applications including pidgin-2.7.0,
gimp-2.6.8, gkrellm-2.3.4, gxine-0.5.903, xchat-2.8.6, xsane-0.996,
and pan-0.133.

- A repository of extra software packages compiled and ready to run.
This includes the Java(TM) 2 Software Development Kit Standard
Edition, an MPlayer browser plugin, and more (see the /extra directory).

- Many more improved and upgraded packages than we can list here. For
a complete list of core packages in Slackware 13.1, see this file:

ftp://ftp.slackware.com/pub/slackware/slackware-13.1/PACKAGES.TXT

Downloading Slackware 13.1:
---------------------------

The full version of Slackware Linux 13.1 is available for download

We will be setting up BitTorrent downloads for the official ISO
images. Stay tuned to http://slackware.com for the latest updates.

Instructions for burning the Slackware tree onto install discs may
be found in the isolinux directory.

Purchasing Slackware on CD-ROM or DVD:
--------------------------------------

Or, please consider purchasing the Slackware Linux 13.1 six CD-ROM
set or deluxe dual-sided DVD release directly from Slackware Linux, and
you'll be helping to support the continued development of Slackware
Linux!

The DVD release has the 32-bit x86 Slackware 13.1 release on one
side, and the 64-bit x86_64 Slackware 13.1 release on the other. Both
sides are bootable for easy installation, and includes everything from
both releases of Slackware 13.1, including the complete source code
trees.

The 6 CD-ROM release of Slackware 13.1 is the 32-bit x86 edition.
It includes a bootable first CD-ROM for easy installation. The 6
CD-ROMs are labeled for easy reference.

The Slackware 13.1 x86 6 CD-ROM set is $49.95 plus shipping, or
choose the Slackware 13.1 x86/x86_64 dual-sided DVD (also $49.95 plus
shipping).

Slackware Linux is also available by subscription. When we release
a new version of Slackware (which is normally once or twice a year) we
ship it to you and bill your credit card for a reduced subscription
price ($32.99 for the CD-ROM set, or $39.95 for the DVD) plus shipping.

For shipping options, see the Slackware store website. Before
ordering express shipping, you may wish to check that we have the
product in stock. We make releases to the net at the same time as disc
production begins, so there is a lag between the online release and the
shipping of media. But, even if you download now you can still buy the
official media later. You'll feel good, be helping the project, and have
a great decorative item perfect for any computer room shelf. :-)

Ordering Information:
---------------------

You can order online at the Slackware Linux store:

http://store.slackware.com

Other Slackware items like t-shirts, caps, pins, and stickers can
also be found here. These will help you find and identify yourself to
your fellow Slackware users. :-)

Order inquiries (including questions about becoming a Slackware
reseller) may be directed to this address: info@slackware.com

Have fun! :^) I hope you find Slackware to be useful, and thanks
very much for your support of this project over the years.

Python in Vim Script

2010-03-30T08:21:00.000-07:00

I realized that we could embed python script in vim script. Thus we can do something that vim script can't do but python can.

In windows vim package, vim only supports for python24. But my python version was python26 therefore I needed to recompile vim or if you're too lazy, you could download compiled gvim.exe and vim.exe for python support at http://www.gooli.org/blog/gvim-72-with-python-2526-support-windows-binaries/ and replace your original gvim.exe and vim.exe with them.

Usually in Linux, vim package is already compiled with python support. You can script python in vim script with no time.

To check python already work in vim, you can type command bellow, if you see the message it means python already works well.
:py print "python in vim"
or
:python print "python in vim"

There are 3 ways to include python code in vim script:

By using python command for example:
python import sys python sys.argv=["foo", "bar"] python print "this's python script"
By using marker:
python << PYSCRIPT #python code here sys.argv=["foo", "bar"] print "this's python script" PYSCRIPT
In example above I use "PYSCRIPT" as python marker, but you can another tag word for you python script marker.
By including file:
pyfile python-script.py

There are some commands vim provided to communicate between python and vim itself, but here I will explain only 2 of them briefly, those are "vim.command" and "vim.eval". Before using them you need to import vim module in python script. You can import it by adding below line in your python code:
import vim

vim.command is used to execute vim command in python script, for example when I want to turn off syntax color, I will add script below:
vim.command("syntax off")

vim.eval is used to get value of variables in vim script, for example :

let s:test_str = "Just test"
python << PYTHON_SCRIPT
import vim
str = vim.eval("s:test_str") 
print str 
PYTHON_SCRIPT

You can get more detail information about python in vim script in vim help
:help python

For further example I tried to create simple tags-setter and ctags-generator by reading it from a configuration file, here is the code.

/home/test/tag-cfg:

tag-file=/home/test/tags
src-dir=/home/test/src-code

/vim/test/tag-gen-set.vim:

let s:conf_file = "/home/test/tag-cfg"
pyfile vim_tags_gen_set.py
py gen_and_set_tags(vim.eval('s:proj_file'))

/vim/test/vim_tags_gen_set.py:

import vim

def dir_trim(str):
    if '/' != str[len(str) - 1]:
    str = str + '/'
    return str

def str_trim(str):
    if '\n' == str[len(str) - 1]:
    str = str[:-1]
    return str

def gen_and_set_tags(proj_file):
    # Open file
    f = open(proj_file, "r")

    # Get project file path
    f.seek(13)
    tmp_str = f.readline()
    tmp_str = str_trim(tmp_str)
    project_file = tmp_str

    # Get tag file path
    f.seek(9,1)
    tmp_str = f.readline()
    tmp_str = str_trim(tmp_str)
    tag_file = tmp_str

    # Get source dir
    f.seek(8,1)
    tmp_str = f.readline()
    tmp_str = str_trim(tmp_str)
    src_dir = tmp_str

    # Close file
    f.flush()
    f.close()

    # Set the commands
    cmd_gen_tags = "!ctags -R -f " + tag_file + " " + src_dir + "/*"
    cmd_set_tags = "set tags=" + tag_file

    print cmd_gen_tags
    print cmd_set_tags

    # Execute the commands
    vim.command(cmd_gen_tags)
    vim.command(cmd_set_tags)

Region Code Protected DVD vs Laptop

2010-02-14T20:25:00.000-08:00

Last Saturday night. I brought home a DVD from my office, I planned to watch the movie in my boarding house. I knew it was illegal but it wouldn't make any sense to the company as long as I had intention to return it back.

Unfortunately the DVD had been protected by region code, its region code was 1 (USA). So I couldn't play it on my laptop :(. I didn't know my DVD ROM region code and it couldn't play the DVD. Thus I assumed my DVD ROM and The DVD had different region code. And for your information I use Windows XP Professional as my operating system.

After searching in Google, finally I found a software which could bypass Region Code Protection. The software was AnyDVD, you can download it from http://www.slysoft.com/en/anydvd.html. It's a commercial software but you can try it for trial for 20 days. By using this software you can set region code to your system to match the DVD region code.

You can change your system region code by right-clicking on AnyDVD systray and choose setting option and then a dialog like below will appear:

Match region code setting to DVD's region code, in my case my dvd's region code is 1 , it means the DVD is only for USA and Canada region. When you finish this configuration, you can play your DVD by using your favorite media player.

Enjoy!, Hope this simple tutorial will be helpful.

Slackware 13.0 released

2009-08-31T18:10:00.000-07:00

It was August 28, 2009 when Slackware 13.0 released. In this version Slackware has supported X64 platform and you can enjoy KDE 4 desktop environment.

As usual you can download Slackware 13.0 from some mirror at http://www.slackware.com/getslack. Choose your mirror, check it, download and enjoy!.

Below is official announcement from www.slackware.com:

Yes it's that time again! After many months of development and careful
testing, we are proud to announce the release of Slackware version 13.0!

We are sure you'll agree that the improvements made in this release more
than warrant the major version bump up from the 12.x series. We've done our
best to bring the latest technology to Slackware while still maintaining the
stability and security that you have come to expect. Slackware is well known
for it's simplicity and the fact that we try to bring software to you in the
condition that the authors intended.

Probably the biggest change is the addition of an official 64-bit port.
While the 32-bit (x86) version continues to be developed, this release brings
to you a complete port to 64-bit (x86_64). We know that many of you have
been waiting eagerly for this, and once you try it you'll see it was well
worth the wait.

Slackware 13.0 brings many updates and enhancements, among which you'll find
two of the most advanced desktop environments available today: Xfce 4.6.1,
a fast and lightweight but visually appealing and easy to use desktop
environment, and KDE 4.2.4, a recent stable release of the new 4.2.x series
of the award-winning K Desktop Environment. We continue to make use of HAL
(Hardware Abstraction Layer) which allows the system administrator to grant
use of various hardware devices according to users' group membership so that
they will be able to use items such as USB flash sticks, USB cameras that
appear like USB storage, portable hard drives, CD and DVD media, MP3 players,
and more, all without requiring sudo, the mount or umount command. Just plug
and play. Properly set up, Slackware's desktop should be suitable for any
level of Linux experience.

Slackware uses the 2.6.29.6 kernel bringing you advanced performance
features such as journaling filesystems, SCSI and ATA RAID volume support,
SATA support, Software RAID, LVM (the Logical Volume Manager), and
encrypted filesystems. Kernel support for X DRI (the Direct Rendering
Interface) brings high-speed hardware accelerated 3D graphics to Linux.

There are two kinds of kernels in Slackware -- the huge kernels, which
contain support for just about every driver in the Linux kernel. These are
primarily intended to be used for installation, but there's no real reason
that you couldn't continue to run them after you have installed. The
other type of kernel is the generic kernel, in which nearly every driver
is built as a module. To use a generic kernel you'll need to build an
initrd to load your filesystem module and possibly your drive controller
or other drivers needed at boot time, configure LILO to load the initrd at
boot, and reinstall LILO. See the docs in /boot after installing for more
information. Slackware's Linux kernels come in both SMP and non-SMP types
now. The SMP kernel supports multiple processors, multi-core CPUs,
HyperThreading, and about every other optimization available. In our own
testing this kernel has proven to be fast, stable, and reliable. We
recommend using the SMP kernel even on single processor machines if it
will run on them.

From the beginning, Slackware has offered a stable and secure Linux
distribution for UNIX veterans as well as an easy-to-use system for
beginners. Slackware includes everything you'll need to run a powerful
server or workstation. Each Slackware package follows the setup and
installation instructions from its author(s) as closely as possible,
offering you the most stable and easily expandable setup.

Here are some of the advanced features of Slackware 13.0:

- Runs the 2.6.29.6 version of the Linux kernel from ftp.kernel.org.
Also included is a kernel patched with Speakup to support speech
synthesizers providing access to Linux for the visually impaired
community. The 2.6.x kernel series has matured into a stable
kernel, and provides reliable performance for your desktop or
your production server.

- System binaries are linked with the GNU C Library, version 2.9.
This version of glibc also has excellent compatibility with
existing binaries.

- X11 based on the X.Org Foundation's modular X Window System.
There's been much activity in the X development world, and the
improvements in terms of performance and hardware support are
too numerous to mention them all here.

- Installs gcc-4.3.3 as the default C, C++, Objective-C,
Fortran-77/95, and Ada 95 compiler.

- Support for fully encrypted network connections with OpenSSL,
OpenSSH, OpenVPN, and GnuPG.

- Apache (httpd) 2.2.13 web server with Dynamic Shared Object
support, SSL, and PHP 5.2.10.

- PCMCIA, CardBus, USB, IEE1394 (FireWire) and ACPI support. This
makes Slackware a great operating system for your laptop.

- The udev dynamic device management system for Linux 2.6.x.
This locates and configures most hardware automatically as it
is added (or removed) from the system, and creates the access
nodes in /dev. It also loads the kernel modules required by
sound cards and other hardware at boot time.

- New development tools, including Perl 5.10.0, Python 2.6.2,
Ruby 1.8.7-p174, Subversion 1.6.4, git-1.6.4, mercurial-1.2.1,
graphical tools like Qt designer and KDevelop, and much more.

- Updated versions of the Slackware package management tools make it
easy to add, remove, upgrade, and make your own Slackware packages.
Package tracking makes it easy to upgrade from Slackware 12.2 to
Slackware 13.0 (see CHANGES_AND_HINTS.TXT). The slackpkg tool can
also help update from an older version of Slackware to a newer one,
and keep your Slackware system up to date. In addition, the
slacktrack utility (in extra/) will help you build and maintain
your own packages.

- Web browsers galore! Includes KDE's Konqueror 4.2.4,
SeaMonkey 1.1.17 (this is the replacement for the Mozilla
Suite), and the immensely popular Firefox 3.5.2, as well as
the Thunderbird 2.0.0.23 email and news client with advanced
junk mail filtering.

- The complete K Desktop Environment (KDE) version 4.2.4, including
the KOffice productivity suite, networking tools, GUI development
with KDevelop, multimedia tools (including the amazing Amarok
music player and K3B disc burning software), the Konqueror web
browser and file manager, dozens of games and utilities,
international language support, and more.

- A collection of GTK+ based applications including pidgin-2.5.9,
gimp-2.6.6, gkrellm-2.3.2, gxine-0.5.903, xchat-2.8.6, xsane-0.996,
and pan-0.133.

- A repository of extra software packages compiled and ready to run.
This includes the Java(TM) 2 Software Development Kit Standard
Edition, an MPlayer browser plugin, alternate Intel video drivers
for X, and more (see the /extra directory).

- Many more improved and upgraded packages than we can list here. For
a complete list of core packages in Slackware 13.0, see this file:

Instructions for burning the Slackware tree onto install discs may be
found in the isolinux directory.

Purchasing Slackware on CD-ROM or DVD:
--------------------------------------

Or, please consider purchasing the Slackware Linux 13.0 six CD-ROM set
or deluxe dual-sided DVD release directly from Slackware Linux, and
you'll be helping to support the continued development of Slackware Linux!

The DVD release has the 32-bit x86 Slackware 13.0 release on one side,
and the 64-bit x86_64 Slackware 13.0 release on the other. Both sides
are bootable for easy installation, and includes everything from both
releases of Slackware 13.0, including the complete source code trees.

The 6 CD-ROM release of Slackware 13.0 is the 32-bit x86 edition. It
includes a bootable first CD-ROM for easy installation, and everything
from the Slackware 13.0 32-bit x86 release is contained on 6 discs
labeled for easy reference.

The Slackware 13.0 x86 6 CD-ROM set is $49.95 plus shipping, or choose
the Slackware 13.0 x86/x86_64 dual-sided DVD (also $49.95 plus shipping).

Slackware Linux is also available by subscription. When we release a new
version of Slackware (which is normally once or twice a year) we ship it
to you and bill your credit card for a reduced subscription price
($32.99 for the CD-ROM set, or $39.95 for the DVD) plus shipping.

For shipping options, see the Slackware store website. Before ordering
express shipping, you may wish to check that we have the product in stock.
We make releases to the net at the same time as disc production begins,
so there is a lag between the online release and the shipping of media.
But, even if you download now you can still buy the official media later.
You'll feel good, be helping the project, and have a great decorative
item perfect for any computer room shelf. :-)

Ordering Information:
---------------------

You can order online at the Slackware Linux store:
http://store.slackware.com

Other Slackware items like t-shirts, caps, pins, and stickers
can also be found here. These will help you find and identify
yourself to your fellow Slackware users. :-)

Order inquiries (including questions about becoming a Slackware
reseller) may be directed to this address:
info@slackware.com

Have fun! :^) I hope you find Slackware to be useful, and thanks
very much for your support of this project over the years.

Install Fedora-8 via Http Server

2009-06-30T06:13:00.000-07:00

Right now we can install fedora via HTTP server, for this we only need http server like apache or other. In this tutorial I use apache as http server, and in my assumption we have set apache server properly.

Copy all of DVD or CD content into Document Root directory; in my case I put it all into fedora-install directory.
Use fedora boot disc or boot usb, use boot.iso file in images directory to create disc or usb boot.
To create usb boot you by using liveusb-creator tool, both for linux and windows, you can get it in https://fedorahosted.org/liveusb-creator/,
Boot Linux by using disc or usb boot.
Choose install system
Choose http install
Set your IP, netmask, and nameserver
Input your http server.
Follow the instruction.
Viola, Linux fedora has been installed in your computer

SU command in OpenBSD

2009-06-16T01:23:00.000-07:00

I have installed Open BSD 4.4 as guest in my Qemu in my Slackware. Firstly after I had finished the installation process I read ‘man afterboot ’ to get early information about what to do, I realize that I should not login as root, but use ‘su’ or ‘sudo’ command to get root access for security reason.

After that, I added a user in my Open BSD system. And I tried to get root access by using ‘su’ command and it fail. To find the solution I did googling, and I found that Open BSD 'su' command can only execute by user in wheel group.

And then I added my user to wheel group by using “usermod –g wheel ” and tested for ‘su’ command again but I failed again to get root access. Because of that I was googling again and found that to add my_user to wheel group I have to modify /etc/group manually or using adduser. I tried that and success.
