Once in a life time, you might want to have big, big, big storage such that no more remove operations are required. I don't know other but I really want to have one. Cluster is a good approach to make my dream come true. There are so many solution out there. I will not talk about commercial product since I don't have enough money support to buy one so this post only focuses on open source solutions.

As of today, Linux Kernel 2.6.x has been hacked for lots of local root exploits. Anyway, it doesn't matter how many they are but it does matter that most of that exploits valid on most Linux stations. One serious case is that they also valid on even cluster distribution like NPACI Rocks. In other words, the whole servers in a cluster maybe exploited for cracking bigger goal, e.g., password decryption. Ones may argue that it is not that dangerous because they are local root exploits, not remote root exploits. Yes, they are. But you have to imagine the power of grid computing where you can run a job seemlessly on remote clusters with automatic executable staging. That's enough. One may exploit the whole grid instantly.

Actually, I don't have my own video except only the screencast captured by ffmpeg on my laptop. That's only one I have by now. So I would like to see how Google Video works and how well it is. As a result, is uploaded successfully. And I also would like to see how to embed into my blog.

Most of my works relate to grid technology and AccessGrid is one of them. I would like to install AccessGrid on my Ubuntu laptop in proper way. I mean to install AccessGrid via standard deb package plus a repository for next installation. Unfortunately, I have not found any sources for rebuilding on Dapper.

Access Grid is a platform for multipoint multimedia conferencing over high-speed network. Comparing to H.323, Access Grid requires a lot more bandwidth to make reasonable video conference because it is decentralized architecture. In other words, there is not bottleneck in Access Grid. That’s why it consumes more bandwidth. Microsoft NetMeeting is a clone of H.323 system so Microsoft needs to propose new conferencing system to compete with Access Grid. Now, the new system called ConferenceXP is in the lab.
