This page lists all of the free web services provided by RogerHub. I add to it occasionally when I make new things, and I clean up old pages if they are unpopular. My goal is to fill up this page with magical useful things, but work and school get in the way. Anyway, please enjoy whatever I do have for you.
Created in 2009, RogerHub’s famous Final Grade Calculator has served over 12.5 million students to date. The calculator will determine how well you need to score on a Final Exam to get the grade you want in a class.
A university admissions calculator built using stastical models derived from the UCOP Statfinder program. This calculator will tell you if students similar to you got into University of California schools in the past.
A tool to calculate your high school GPA, based on the University of California’s guidelines.
Roger created the RatLang Programming Language, a replacement for the command-line calculator. Check out and build the code.
An experimental SMTP mail exchanger written in the Go programming langauge with basic networking and language libraries. Mailman is fully capable of interacting with other mail exchangers and implements the RFC5321 standard.
