Projects

Client/Server Systems

• Much of the backend java servlet programming for an Internet startup
• Apache modifications for an Internet startup

• Multi-threaded Web server testing utility

  This system was written in Java to provide information to simulate user interaction in a Customer Service System. It provided timing information and load testing.

• Java Performance tuning.

  Determining the bottlenecks in a large java application and re-writing the relevant sections in either Java of C++ to reduce the performance penalty.

• FastCGI applications in Java for Apache.

  Also produced a FastCGI authorizer module for Apache.

• Network Management Station

  This product was written primarily in Tcl/Tk.

• High Performance Image Keying Systems

  This system was designed for the SunOs/Solaris environment. The keying terminals were NCD Xterminals. The code was developed in an object oriented manner in the C language.

• Globally Distributed Video Conferencing System

  This system, written in C++ for the SunOs environment had to be scalable from single systems to a globally distributed system.

• Mission Critical System Administration

  HP and SUN Systems administrator in a production environment. This includes all the usual things such as: 24x7 emergency support, upgrades, installations, patches, hardware repairs, and vendor application support. Larger applications currently being supported:

  • High-Availability Software: Service Guard (HP)
  • Monitoring systems: OpC, Tivoli, Ensign
  • Backup systems: Omniback, Epoch
  • Warehouse applications:
    • SAP - basis only [add users, monitoring, installation/upgrades, printers, fax software (merkur), shutdown/startup, sapdba, a little cts, general debugging]
    • Redbrick

  • Databases: Sybase/Oracle [installations/upgrades, related tools, startup/shutdown, recoveries, add users only]

X11/Motif

• HTML Widget

  An widget for displaying HTML text for commercial applications.

• Document Transport Operator User Interface

  A Port of a legacy operator user interface system from a proprietary graphics system to Solaris/X11/Motif.

• Image Processing Extension (SIE) for proprietary graphics cards

  Implemented the NCD Simple Image Extension for a proprietary graphics card.

• X11 Servers for proprietary graphics cards
• We support and use linux
• We support and use freebsd

• We support and use Apache and a Apache-SSL

DLL's

• Implemented financial modeling package as DLL set for excel5.0

Free Software

Simple SetTime utility for NT

This has been tested under NT 3.51. If your time server is a linux box, you will need to run -l. If it is a bsd box, you will need -b. It uses the 'time' service from inetd, which returns the current time in seconds since Jan 1, 1970 as a long. The linux time is biased to a different base date. The code then adjusts this into the base time of the NT box, (Jan 1, 1900) and sets the time. It needs the the adjust and query privilege on SYSTEM TIME to run. This code has not been tested under NT4.X, or under Win95. It relies on a simple socket library that I can't release source for.

• Binary

• Zip of source and binary

Multi threaded FCGI   java libraries

Here's a way to multi-thread your fcgi scripts - for FREE

• Multi threaded FCGI java libraries Use the FCGIInstance object's in,out,err and getProperties and getQueryString then call finish on it when done. FCGIAccept() returns an FCGIInstance object. Note: I haven't used this code in a year or so, and only just now got the ok to release it.
