    Little Book of Linear Algebra

    Little Book of Linear Algebra

    A concise, beginner-friendly introduction to the core ideas of linear

    ...There is also a companion “LAB” section for hands-on exploration (e.g. using Python/NumPy) to help cement the connections between algebraic formulas and computational behavior. The exposition aims to sit between a pop-math summary and a heavy textbook: definitions and key theorems are stated cleanly, while proofs are sometimes omitted or sketched to keep the flow digestible. Because of its brevity and clarity, it's especially useful as a first pass for learners who want a solid map of the subject before diving into full textbooks.

    Tibetan Phonetic Keyboard

    Keyboard that uses English phonetic for typing Tibetan characters

    ...There are more than 26 alphabets in Tibetan hence it is not possible to match all alphabets on just the English alphabet keys and some of the Tibetan characters are mapped onto symbol keys. Vowels are entered by "e", "i", "o", "u". By pressing the SHIFT key + alphabet , one can get the alphabet as a Tibetan lower stack character. Less often used characters, such as "laterally flipped" alphabets, and symbols are found using Alt + Ctrl+ [some key]. Special lower stack characters are found by using Alt + Ctrl+ Shift+[some key]. This keyboard has been put to use in digitizing a Tibetan prayer text that about 100 pages long. ...

    clavirio

    Learn touch typing without leaving the terminal

    ...Progressive lessons, practice modes, real-time stats, and a virtual keyboard with finger hints — for QWERTY, Dvorak, and Colemak. Methodology Research on typing skill suggests that skilled typing relies more on implicit procedural control than on explicit knowledge of key locations. The paper also suggests that the keyboard is represented in terms of its row-and-column structure, not as a memorized list of individual letters. Clavirio follows that idea by teaching the keyboard row by row with the same 7-lesson progression for each row: index pair → middle pair → ring pair → pinky pair → reach pair → full row → row + Shift Each lesson introduces only 2 new keys and uses only characters from earlier lessons. ...
