What’s Your PIN?

I found an interesting article today studying the frequency of PIN usage on the iPhone. If you have an easily guessable PIN number then you really are doing yourself a disservice. I’d bet that people who use these common PIN numbers on their iPhones use them everywhere else as well. If you find yourself in [...]

Generating Thousands Of Random Passwords

Occasionally at work I am called upon to pick passwords for my end users. They would prefer that I use passwords like “password” or “1234567890.” We all know how secure that is. I prefer to randomly generate a password for them. I have a website bookmarked that I use to generate a few passwords at [...]

SSL Identification Errors

Our clergy e-mail server at work is running a Thawte SSL123 certificate for securing all webmail, POP/SSL and SMTP/SSL traffic.  They have been an excellent certificate authority and we have used them for several years now.  Unfortunately, the certificate in question expired over the weekend.  I was supposed to renew it late Saturday night or [...]

Required Mailman Permissions

I have been spending a good deal of time in our mailing list server archives trying to run down several permissions related problems.  After doing a great deal of searching online I realized that there was no place online that listed the comprehensive required permissions for the /var/lib/mailman/archives and /var/lib/mailman/lists folders.  I spent a few [...]

Practice Safe Searching

As I was navigating the internet today at work I noticed a new Google feature that seems rather interesting: Google has released the beta version of their https encrypted search website.  Google probably didn’t encrypt their searches from the beginning due to the increased overhead of the https protocol.  After several test searches I cannot [...]

Social Networks Redirect Issue

While managing the network infrastructure at our Annual Conference I have run across a weird redirect issue.  All of the computers in the News Room running Windows XP, Vista and 7 started redirecting to MySpace pages.  In the beginning it was redirecting to an actual profile.  After an hour or so the website started returning [...]

Google Stands Up To China

Google is taking a courageous stand against China.  Good for them! We launched Google.cn in January 2006 in the belief that the benefits of increased access to information for people in China and a more open Internet outweighed our discomfort in agreeing to censor some results. At the time we made clear that “we will carefully [...]
