I spoke on my experiences as a TA for Sys Admin education at LISA 07. Find some information here.
You can find the Inspiron 6000 part numbers here.
Inspiron 6000 makes a lot of noise after a few years of service. I found this amazing software that automatically switches off and on the fan depending on the temperature of the system. It works great for me! By the way, I bought a new fan, bluetooth and memory module from Dell for my old laptop. I am expecting it to work like a charm.
The software for fan control can be found here!
I was nominating one of my friends as a Sysadmin Rockstar of the year. I heard the song on the website. Its just awesome! Just got to listen to it.
Our paper, “RepuScore: Collaborative Reputation Management Framework for Email Infrastructure” has been accepted at LISA 07 to be held in Dallas, TX.
Spammers *were* attaching images with spam. The tools used are actually sophisticated, such that, the placement of a pixel here and there are altered thwarting tools that perform image analysis (or a simple hash of the image) to determine if the email is spam.
Looks like the good old days are over! Move over image spam, here come the pdf spam!
I was surprised this afternoon to see an spam email in my inbox attached with a PDF! A regular spam image was the content of the PDF. Yes, I have been a good netizen and reported the email to Microsoft for further analysis.
Actually, it is no wonder to see this happening. I would think we might see some small mp3 attached spam, video attached spam or for that matter any other service by passing spam. I don’t think the solution to spam is to analyze the spam. It is to characterize the sender based on the past behavior would help. I believe that my present research in the field of sender reputation systems could help.
