Crack WPA

Wireless connection is never secure. I have been cracked a WEP password in 10 minutes with BT3 and an enhanced wireless receiver. But it is been difficult to break WPA encrypted wireless connection as it requires dictionary brute force, which typically takes days or weeks in a standalone PC. But things are quite different if the cracking is performed parallelly by hundreds of machines. The WPACracker team offers such a service, that you can run your network capture against their 400-CPU cluster, thus significantly reduce the time to 20 mintues. You need to pay $17 for that service.

Vmware7+WinXP+Ubuntu

I installed Vmware7 in Windows XP, for code version control purpose, installed one Ubuntu 9.10. The virtual network was setup to work in bridged mode, which means the guest OS (Ubuntu) has a logically seperate Ethernet interface, and the IP address is in the same LAN as host OS (WinXP). After that, I can access svn service from any other machines within the LAN, the problem occurred when I tried to checkout code from host OS. TotoriseSVN complains connection to svn server failed. After googling for a while, I found someone had similar problem as me, and that was caused by a bug in vmware 7 and it affects "Realtek RTL8169/8110 Family Gigabit Ethernet NIC". Fortunately, there is one workaroud: disable the "Offload checksum" in the deveice driver manage page. I tried, it works! The other remedy will be more complicated, setup the network mode to NAT, and forward any traffic you want pass to the guest OS, e.g., svn in vmware NAT settings. I didn't try that. Refer to original post for this issue.

High Speed Wireless

There is an article reviewed three different high speed wireless standards,

• WiGig
• WHDI
• SiBEAM

WiGig works at 60-gigaherz wireless spectrum, creates a 10-meter range with transmit speed up to 7 gigabits per second, which is almost 11 times of 802.11n speed (600 megabits per second). WHDI puts more weight on multimedia content delivery, especially for high definition video, it uses 5 gigaherz spectrum with throughput up to 3 gigabits per second, with a range of 100 meters. SiBEAM also uses 60-gigaherz spectrum and provides multi gigabits/second capability, makes it a strong candidator for replacing existing cables in your home.

Back to video, all above standards requires video be digitized before being transmitted over the wireless link. Well, there is another standard called HDcctv, which aims to transmit high definition (720p, 1080p) video over coaxial cable without digitization and packetization, the throughput is up to 3Gbps. Unfortunately, HDcctv also has two competitors, PSIA and ONVIF.
Let's see who will become dominant standards for streaming high definition digital video and analog video!

iPad

iPad was first on sale on Apr 3, to my knowledge, it is not just an ipod touch with big screen. It enables many rich media applications which are not optimized in small screen device like iphone. This version supports wi-fi and bluetooth, and next version will support 3G network. It is a picture frame, a news paper, a movie theater, a skype phone, a game station, ... what ever you named it. I shall buy one and try home dashboard on it. There is one article talks about it from Sina

Home dashboard

I was thinking a board with full customized capbility, with a 9 inch LCD, you may drag and drop pre-built widget such as weather, stock, transportation, sports, news into the display area, the device will deliver the information timely; It shall be able to download and playback the pictures/videos in your camera or camcorder so that you don't need to connect the camera to the computer manully; more over, it can connect to your web/security camera, display who is in your front door. Finally, the device is able to be powered by a battery like a cell phone.

In one word, home dashboard brings various convenience to your daily life and makes your home looks modern. The question is how much you will pay for the device?
