Also, note that the 3GS’ performance mimics that of the Palm Pre - another Cortex A8 based phone.Not too surprising given the just-released nature of the Pre’s webOS, the 3GS is actually able to render webpages slightly faster than the Pre in some cases.

How to configure Ubuntu 8.10 / 9.04 for 802.1x WPA TKIP environment
IIUM wireless environment implement WPA authentication and TKIP encryption. The overall using 802.1x authentication method which deploy protected EAP (PEAP) using EAP token. User database stored in a Radius server by using FreeRadius running on FreeBSD platform.
When Ubuntu come out with new release, 9.04 and 9.10 alpha, my friend was exciting because the new relase might help student who really like ( dont know why, yet Ubuntu still look nothing for me) to have a great bonding with Ubuntu, but the result is still disappointing. The main issue is that since the release 8.10 version, Ubuntu has come with standard Network Manager with not support of PEAP/TKIP, the main authentication for IIUM wireless connection. So, the best solution for this is to swtich to Wicd, the open source Gnome-independency Network manager.
1. Get the Wicd either direct download by using command terminal sudo apt-get install wicd , or just download from Synaptic Package Manager for those who dont want to play around with command terminal.
using command
sudo apt -get install wicd
using synaptic package manager
2. Go to etc/wicd/encryption/templates/peap-tkip to customize the setting. Please take note that ubuntu has by default disable the root password. So you cannot just simple open form file browser. You can either open the file using command sudo ect/wicd/…../peap-tkip at terminal or just type on terminal “sudo passwd root” to enable you root password. Please also take not the file is located at the root folder, not home folder.
Change this:
name = PEAP with TKIP
author = Fralaltro
version = 1
require identity *Identity password *Password ca_cert *Path_to_CA_Cert
-----
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="$_ESSID"
scan_ssid=$_SCAN
proto=WPA
key_mgmt=WPA-EAP
pairwise=TKIP
group=TKIP
eap=PEAP
identity="$_IDENTITY"
password="$_PASSWORD"
ca_cert="$_CA_CERT"
phase1="peaplabel=0"
phase2="auth=MSHAPV2"
}
to become this:
name = PEAP with TKIP
author = Fralaltro
version = 1
require identity *Identity password *Password
-----
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="$_ESSID"
scan_ssid=$_SCAN
proto=WPA
key_mgmt=WPA-EAP
pairwise=TKIP
group=TKIP
eap=PEAP
identity="$_IDENTITY"
password="$_PASSWORD"
phase1="peaplabel=0"
phase2="auth=EAP Token"
}
3. After that, go to Application > Internet > Wicd Network Manager. select iium community and click on Advanced Setting. Tick Use Encryption and select PEAP with TKIP.
Then, just type your username and password….and thats it and it works…

Windows 7 vs OS X Snow Leopard
Exchange Support
Snow Leopard's got it built-in, your copy of Windows 7 doesn't. Freaky but true.
Overall
Both Windows 7 and Snow Leopard are designed to be faster, leaner, stronger and more stable than the OSes they're building on. Windows 7 is markedly more responsive, and you simply feel like you're more in control. We'll have to see with Snow Leopard, but if it lives up to Apple's promises, we're definitely looking forward to the performance prowess.
There' s a whole lot that goes into deciding whether you're a Mac or PC, but whatever one you pick, you definitely won't go wrong upgrading your OS this fall.

Review on Aruba RAP-2WG Remote Access Poin
The Aruba RAP-2WG is a single radio 802.11b/g, enterprise-class indoor remote access point, capable of supporting multiple functions including wired and wireless access and air monitoring/wireless intrusion detection and prevention across the 2.4-2.5 GHz spectrum.
The RAP-2WG remote access point delivers secure user-centric network services and applications in remote branch offices as well as for home office workers and telecommuters. Centrally managed from an Aruba Controller, the RAP-2WG provides the network administrator with unparalleled control over services and security. The RAP-2WG supports authenticated wired and wireless access, as well as policy based forwarding mechanisms to allow access to centralized and local resources.
The latest product Aruba's Virtual Branch Network (VBN) solution dramatically simplifies the complexity and cost of deploying a remote solution at branches with one to many users. Complex configuration, management, software updates authentication, intrusion detection, and remote site connectivity tasks are handled by powerful data center-based Aruba controllers running new Aruba software. Centralizing these services in the controllers enables the branch office equipment to be greatly simplified and cost reduced. The virtualized functions are transport-independent, so any wide-area network - including 3G cellular and DSL - can be used to connect the branches offices.
