First Week August
I know the last month was fucking lazy, but August I think is different, the first week:
CentOS 5.5 setup on VirtualBox with LAMP
Download the netinstall ISO from mirrors:
- CentOS-5.5-i386-netinstall.iso
- CentOS-5.5-x86_64-netinstall.iso
[HTTP Setup]
Website name: mirror.centos.org
CentOS Directory: centos/5.5/os/i386
After many screens select only server
Set up LAMP on CentOS 5.5 Server:
yum install mysql-server # mysql server
yum install php-mysql # php with mysql
/etc/init.d/mysqld start # start mysql (password empty)
# put mysqld and httpd in run levels
chkconfig mysqld --level 2345 on
chkconfig httpd --level 2345 on # httpd is all ready
If you want to start CentOS on background:
# Port forward SSH to 2222 localhost:
VBoxManage modifyvm "CentOS" --natpf1 "guestsssh,tcp,,2222,,22"
# Port forward HTTP to 8080 localhost:
VBoxManage modifyvm "CentOS" --natpf1 "guestshttp,tcp,,8080,,80"
# bash aliases
alias start_centos='VBoxManage startvm "CentOS" --type headless'
alias centos='ssh -p 2222 root@localhost'
Make twitter useful:
# goto http://code.google.com/p/python-twitter/ on ubuntu:
apt-get install python-twitter
#!/usr/bin/env python
# -*- coding: UTF-8 -*-

api = twitter.Api(username, password)
statuses = api.GetUserTimeline(USER_YOU_FOLLOW)
msgs = [s.text for s in statuses]
last_msg = msgs[0]

FTP for Developers
This examples upload a simple text file for a better implementations read the API or documentation for each language or command
Curl:
curl -T filename -u username:password ftp://hostname/filename
Perl:
use Net::FTP;
$hostname = "localhost";
$username = "user";
$password = "pass";
$filename = "file.txt";
$ftp = Net::FTP->new($hostname);
$ftp->login($username,$password);
$ftp->put($filename);
$ftp->quit;
To handle errors use “or die $@” (“$ftp>message” only if login success)
PHP:
<?php
$hostname = "localhost";
$username = "user";
$password = "pass";
$filename = "file.txt";
$conn = ftp_connect($hostname);
ftp_login($conn, $username, $password);
ftp_put($conn,$filename,$filename,FTP_ASCII);
ftp_close($conn);
?>
To handle erros you can use “if(!function)”
Python:
import ftplib
hostname = "localhost"
username = "user"
password = "pass"
filename = "file.txt"
ftp = ftplib.FTP(hostname)
ftp.login(username, password)
ftp.storlines("STOR " + filename, open(filename))
ftp.quit()To handle errors use “try” and “except” and “else”
Ruby:
require 'net/ftp'
host = 'localhost'
user = 'user'
pass = 'pass'
file = 'file.txt'
ftp = Net::FTP.new(hostname)
ftp.login(username,password)
ftp.puttextfile(filename)
ftp.close
To handle errors use “begin”, “rescue”, “else”, “ensure” and “end”.
Win32 batch:
ftp -s:settings.txt hostname
settings.txt:
username
password
put filename
bye
To handle errors use “if not %errorlevel%==0 goto :error”

Python 3.0 Final Released
Python 3.0 (a.k.a. “Python 3000″ or “Py3k”) is a new version of the language that is incompatible with the 2.x line of releases. The language is mostly the same, but many details, especially how built-in objects like dictionaries and strings work, have changed considerably, and a lot of deprecated features have finally been removed. Also, the standard library has been reorganized in a few prominent places.
