#sudo apt-get install php5-gd

then, restart web service

#sudo service lighttpd restart //or
#sudo service apache2 restart

#make clean

#make modules_install

then, generate a image for new kernel.

#cd /lib/modules
#mkinitramfs -o initrd.img-2.6.30.4 2.6.30.4
#mv initrd.img-2.6.30.4 /boot

edit menu.lst file for grub booter, add following:

title		Ubuntu 8.04.3 LTS, kernel 2.6.30.4
root		(hd0,2)
kernel		/boot/vmlinuz root=UUID=98f69044-be12-4dde-95df-358dca35c632 ro quiet splash
initrd		/boot/initrd.img-2.6.30.4
quiet

Checking for ELILO…No

GRUB is installed. To automatically switch to new kernels, point your
default entry in menu.lst to /boot/vmlinuz-2.6.30.4

====================
GRUB menu configuration file menu.lst should be update.

using root account do following.

#make mrproper #check kernel .o and .config files

next configuration kernel. there are three kinds of configuration UI.

#make config #Text UI

#make menuconfig #Text graph UI

#make xconfig

before using menuconfig mode, ncurses should be installed.

#apt-get install libncurses*

and before using xconfig mode, following package should be installed.

#apt-get install libqt3-headers libqt3-mt-dev

after all configuration work done. using make command to compile kernel.

$sudo wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.30.4.tar.gz /usr/src
$sudo tar xvf /usr/src/linux-2.6.30.4.tar.gz

if linux-2.6.30.4.tar.bz2 package, using command:

$sudo tar jxvf /usr/src/linux-2.6.30.4.tar.bz2

$sudo passwd root

then, set new password for root.

mysql -p -u root

$pacman -S samba

$cp /etc/samba/smb.conf.default /etc/samba/smb.conf

$adduser -d /home/<user dir> -m <user name>

$passwd <user name>

$smbpasswd -a <user name>

add two lines in to /etc/samba/smb.conf

netbios name = archsmb

encrypt passwords = yes

[homes]

browseable = yes

writable = yes

then:

$/etc/rc.d/samba start

$smbclient -L localhost -U <user name>

deamons(… sshd lighttpd … …)

sshd: ALL

pacman -Ss search

pacman -S lighttpd php fcgi mysql samba perl-cgi

add following lines to /etc/rc.conf

eth0=”dhcp”
INTERFACES=(eth0)
ROUTES=(!gateway)

then try /etc/rc.d/network restart

>>>import time

>>>time.time()

//currenting timestamp to int

>>>int(time.time())

//converting to string

>>>str(time.time())

python-twitter

python-simplejson

first install python-simplejson, if in ubuntu, just using command as follows

$apt-get install python-simplejson

then, downloading python-twitter , unpackage it. then using command

  $ python setup.py build
  $ python setup.py install

then, open python.

>>> import twitter

>>> api = twitter.Api(“username”, “passworld”)

>>> posts = api.GetFriendsTimeline(‘username’)

>>> print [post.text in post as posts ];

for the file, the script should be liked:

import twitter
class mytwitter():

if __name__ == "__main__":
main()


mount -o loop -t iso9660 file.iso /mnt/test

1. install dhcp3 server in the ubuntu.

apt-get install dhcp3-server

2. edit /etc/default/dhcp3-server

INTERFACES=”eth0″
3. edit /etc/dhcp3/dhcpd.conf
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.254;
option domain-name-servers 192.168.1.1, 192.168.1.2;
option domain-name "mydomain.example";

subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.10 192.168.1.100;
range 192.168.1.150 192.168.1.200;
}

4. edit /etc/network/interfaces

auto eth0:1

iface eth0:1 inet static

name DHCPserver

address 192.168.1.1

netmask 255.255.255.0

5. restart networking and dhcp3

service networking restart

service dhcp3-server restart

via curl command in linux, 1 and 2.

Using twitter php client.

official API tutorial.

firstly, install ruby

next, install rails, by command “gem install rails”

then, create a new web app by rails by “rails project”.

if “project” has been create, it can be runned by command “ruby script/server webrick”.

lastly, open address “http://localhost:3000″ web browser.

$rdesktop -f <ip address>

-f is mean full screen.

pacman using wget for download task. but wget is not for multiple thread download. if using “aria2″, the download speed can sharply increase.

firstly, install aria2 by:

$pacman -Sy

$pacman -S aria2

then, edit /etc/pacman.conf, add a line:

XferCommand = /usr/bin/aria2c -s 2 -m 2 -d / -o %o %u

ok, try pacman again, you can see big change for download speed.

open /etc/kde3/kdm/kdmrc

change “AutoLoginEnable” to false

$badblocks -c -v /dev/sda1

-c blocks at once
-v verbose mode

in the freebsd system, smart montools can be used:

$cd /usr/ports/sysutils/smartmontools
$make config install clean
$smartctl -a /dev/ad0 // quick checking and check all
$smartctl -t long /dev/ad0 // check and test


SpringGraph is a 2D data visualization API based on the flex 2. I have used flex 3 sdk to demo the example of spring graph.

first of all, a package should be downloaded for using SpringGraph at developer blog. Extracting the package, copy ./SpringGraph/bin/SpringGraph.swc to the directory named simple.

The package provides five examples for testing SpringGraph. going into simple SpringGraphDemo. using command to compile the mxml file, like:
mxmlc -library-path+=../SpringGraph.swc SpringGraphDemo.mxml

than using a flash player open SpringGraphDemo.swf. the interface should like this example.
