Advent Calendar 11
Not to make this sound like an ad, but an important event of 2025 was creating from scratch my own lightweight, user-friendly course platform, which I grandly named «Stukalin Academy».
The system is built very simply. It has almost no back end; it runs almost entirely on JavaScript, and only file-system operations on the server side are handled by the back end. For each learner registered on the platform, a folder is created using a hash of their encrypted email with a secret salt. In other words, even I cannot tell who is who. That is the core protection: no personal information and no passwords.
I create learning materials and courses for students, including hands-on exercises and interactive tests. For now, these courses are used as an add-on to live online lessons, but someday I will find the time to record and digitize everything, and then the platform will really come alive. So go ahead — sign up, request access through the application form, and learn. I would be glad to get feedback.
