In my many years as a developer, I have worked on several projects. Many of those projects are for the TI graphing calculator, others are websites, or servers I have created. Some of these projects involve calculator programming as well as a website and server programming (usually Python). For details, see the list below. Clicking on the list items in most cases will take you to a project page for more information.
HASHLIB | CE Cryptography Library
HASHLIB was a project that started out as a hashing library and soon evolved into a library providing industry-standard cryptography on the TI-84+ CE.
VAPOR | TI-84+ CE Package Manager
Vapor Package Manager, or VPM for short, simplifies installation and update of software on your TI graphing calculator. It works similar to apt, Homebrew, and other *nix-style package managers.
TI-Trek | TI-84+ MMO Space Combat
Project TI-Trek is an effort to create a multiplayer space-combat game for the TI-84+ CE. Still in early alpha, the teaser releases feature networking and encryption of the login session.
BLAST TI File Integrity Software
BLAST FIS aims to bring software tracking and file snapshot features to the TI-84+ CE. The software also has the ability to scan files as well as the operating system for malware based on a community-sourced definitions file.
