cargo install --locked

While installing cargo-generate I ran into an error compiling caused by missing type annotations in cargo itself.

link:e0283.txt[role=include]

An already-closed issue in Cargo explained that the issue originated in the serde crate, and was already resolved. While waiting for a patched release, users were advised to use cargo install --locked.

Visualising recursive function calls in Elixir

For SICP Exercise 1.14 in Elixir, we'll first implement the count_change/1 function, which calculates how many different ways there are to make change using half-dollars (50 ¢), quarters (5 ¢), dimes (5 ¢) and pennies (1 ¢) for any given amount of money.

iex -r counting_change.exs
