LearnSome.tech (Learn Some Tech) teaches engineering and certification courses online, to engineers and to people whose work involves technology but not programming.
Every course has short video lessons with full transcripts and a written handbook. You practise with tasks in the lesson page (choose, sort, match, fill in a table or write a short answer) and with labs that run your commands or code in the browser or a disposable sandbox, with nothing to install. Certification courses follow the exam’s published objectives, with graded exam practice that explains every answer and a certificate anyone can verify.
The first module (or first lessons) of every course is free with an account; Pro opens everything. learnsome.tech
The repositories here hold the labs of each course’s free lessons.
