Marcus J. Ranum

I am a metal artist and fabricator, formerly a computer security consultant, speaker, teacher, and system design specialist.

Are you interested in a knife or some other kind of metal-worked sharp stabby pretty thing? If so, contact me. If you are interested in computer security, my availability is fairly thin – I’m only accepting projects that are particularly compelling or fascinating. Offer me a new metal lathe or a CNC mill and you might get my attention.

These pages are mostly where I am going to archive notes, and post images I can link to if I want to display them somewhere, out there. I am not putting a lot of work into presentation, image layout, or text.
