I had meant to put these up as .PDFs, but it appears ACM archives LJ articles once they go public (~30 days after the magazine comes out). Enjoy. How to configure SIP and NAT Expose VoIP Problems Using Wireshark

The folks over at Proven Scaling offered to send three people to the MySQL conference in Santa Clara at the end of the month. I put my name in and won! Unfortunately my wife’s at a conference herself those days, so I can’t go. Major bummer! I think it’s wonderful that a company is offering [...]

I like LinkedIn. It’s a handy way of keeping in touch with old friends. Often I’ll see one of my contacts add another contact who I know from a long time ago, which leads me to getting back in touch. I like it better than other services I’ve tried. I downloaded the Outlook Toolbar for [...]

I submitted two articles to Linux Journal in December and I’m happy to see they’re both feature articles in March’s VoIP issue. How to configure SIP and NAT Expose VoIP problems with Wireshark Special thanks to Bill Reid, John Lange, and Les Bester of Les.net for letting me bounce ideas off of them, and again [...]

I put in my two weeks notice at Ceridian on Friday. For reasons I’m keeping to myself, I haven’t told anyone where I’m going, what I’ll be doing, or where the job is. I have to admit, the rampant speculation is a great source of amusement! Quitting is always a pain because you’re comfortable where [...]

The article: Opinion: ‘Student’ CISSPs put cert’s value in [...]

Notably, I’m writing a few articles for IBM DeveloperWorks on Unix performance monitoring which I’ll link to here once they go live. [...]

I was reading through some of the notes from the talks at NANOG, the North America Network Operators Group. In particular, notes about the transition to IPv6 caught my eye. I’ll be the first to admit I don’t know enough about the protocol, but what always struck me as odd was that there’s no multihoming [...]

I’m looking at making the move to WordPress. So far I’ve got no problems with the import and the url redirection, but I make use of a plugin called “MTCollect” that lets me scour the post for urls and post them. I described it here I’ve looked around and can’t seem to find the same [...]

Every so often I like to play with Google AdWords to see if I can make a couple of bucks (usually when I find a free coupon, that is). One thing that’s a pain is generating keyword lists from smaller lists. I wrote a small CGI program, available at http://ertw.com/cgi-bin/kw.cgi , that takes lists of [...]
