The GridNotes iOS app does not collect any user data of any kind. The app does not access the Internet at all.
It is just a musical instrument.

Here's an attempt at understanding the structure of musical scales.

I saw these cute little adhesive heat sinks on eBay:

A basic constant-current source or sink can be constructed from a Zener, a BJT, and a few resistors.

Let's simulate a zener diode voltage regulator using LTspice.

Some flashcards on Haskell syntax (work-in-progress).
How do you load the haskell file foo.hs from ghci?
| SDL=$(shell sdl-config --cflags --libs) | |
| default: snake run | |
| run: snake | |
| ./snake | |
| snake: snake.c | |
| gcc -std=c99 -Wall -Werror $(SDL) snake.c -o snake |
This script downloads one of the QEMU images from https://people.debian.org/~aurel32/qemu/ and boots up a vm.
(unfortunately, these are all wheezy images, which is quite old now, but still useful for e.g. compiling a C file or running a binary)
Usage examples:
| #include "HashTable.h" | |
| #include <stdio.h> // fprintf | |
| #include <stdlib.h> // exit | |
| #include <string.h> // memset | |
| #include <stdint.h> // uint8_t | |
| #include <stdbool.h> // true | |
| #include <assert.h> // assert | |
| void* dmalloc(size_t size) { |
