Current Projects

Macintosh

• Bifurcation Chaos
  This program analyzes the behavior of the logistic function: µx(1 - x) by graphing the fixed points vs. the parameter µ;. This code was origrinaly written for the macintosh.
  
  
• DNS Lookup
  I wrote this program, because there was no nslookup port for the Macintosh. DNS Lookup is also available at any info-mac macintosh software site. As usual, I always welcome any comments or suggestions for improvement.
  
  

UNIX

• Integer Factorization
  Ami Fischman and I have been futzing around with some factoring algorithms ever since we both gave seminar lectures on Eliptical Curves. If you are interested in this sort of stuff, check out my factoring home page!
  
  
• tcpstat
  tcpstat reports certain network interface statistics much like vmstat(8) does for system statistics. tcpstat gets its information by either monitoring a specific interface, or by reading previously saved tcpdump(1) data from a file.
  
  
• tripwire
  tripwire became opensource, but still is missing some things. I've put together a patchset which includes some new features, and support for other OSes.
  
  
• vmstatd (work in progress, not yet available)
  vmstatd is a dæmon which collects system stats like vmstat(8) does, and stores the information in a MySQL databank.
  
  
• dsp (work in progress, not yet available)
  dsp started out as a project for the Mac (it's done if you are interested in compiling the code in CodeWarrior...) which I decided to port to unix. dsp is a graphical signal processing tool, which lets you edit audio files based on common advanced DSP algorythms like
  • IIR Filtering (Butterworth, Chebychev, Elliptical, Bessel, etc...)
  • FIR Filtering (Rectangle, Triangle, Hamm, Hamming, Blackman, Kaiser, etc...)
  • Phase, Flange, Compression (single and multiband), Exiter
  • Many others.
