Here are some additional resources of potential interest to my students.

Student Resources. If you are a student taking one of my classes, you may find the links here useful.
The XNetwork is a testbed of physical (not simulated) devices that support the CIS program's networking classes.
Tutorial on C. A semester long course in C for first time programmers. This tutorial also covers some advanced topics. GitHub repository.
Tutorial on C++. This is a work in progress. This tutorial assumes C experience. GitHub repository.
Tutorial on Ada. Source files for the various sample programs used in the tutorial. This is a work in progress. GitHub repository.
Unix Overview. This is a description of Unix that applies, more or less, to any Unix-like system. GitHub repository.
Tutorial on POSIX threads. This tutorial covers both POSIX threads specifically and some thread programming topics in general. GitHub repository.
In some classes, I use the Open Watcom C/C++ compilers. Here I provide a snapshot of the development version. To install, unpack the snapshot in some suitable location (avoid paths with spaces). To use, open a console and run the useOW script in the root of the distribution to set up the environment of that console.
My Curriculum Vitae.

Projects

Links to projects I'm working on:

pchapin's GitHub. Use this as a starting point to access the various open source projects I'm contributing to or maintaining.
Open Watcom. An open source C, C++, and Fortran compiler suite with tools. I have been an active contributor to this project in the past.
Astronomical Observations. Various observations made by me and the home for "Astronomical Observation Markup Language."
Waterfalls of the New England Region. A page showcasing waterfalls around New England that I have visited.
100 Highest. A list of the 100 highest mountains in New England along with climbing notes.
Technically Rambling is my blog about various technical things I sometimes think about.

Links to projects I have worked on in the past:

CubeSat Laboratory is a group of VTC students, faculty, and staff working on CubeSat technology spacecraft. See also the Flying SPARKs blog for updates about their work. Although I was very involved in this project for a number of years, I am no longer actively participating.
