Jeffrey A. Poskanzer is a computer programmer. He was the first person to post a weekly FAQ to Usenet. He developed the portable pixmap file format and Pbmplus (the precursor to the Netpbm package) to manipulate it.[1] He owns the internet address acme.com (which is notable for receiving over one million e-mail spams a day), and worked on the team that ported A/UX.[2] He has shared in two USENIX Lifetime Achievement Awards - in 1993 for Berkeley Unix, and in 1996 for the Software Tools Project.
