Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Setting up pass on git with a gpg key

The following shell transcript shows how to:

  • Create a GPG key
  • Create a pass database
  • Add git support to the pass database
  • Create a remote git repository
  • Push the pass database to the remote git repository
  • Fetch and display your passwords from another host

It is assumed that the pass package has been installed on both the first and second computers.

| Pi of term * (term -> term)
| Appl of term * term
| Ann of term * term
| FreeVar of int
| Star
| Box
let unfurl lvl f = f (FreeVar lvl)

Laymans explanation of delimited continuations with examples of using them for exception handling and nondeterministic programming.

Delimited Continuations

Delimited continuations manipulate the control flow of programs. Similar to control structures like conditionals or loops they allow to deviate from a sequential flow of control.

We use exception handling as another example for control flow manipulation and later show how to implement it using delimited continuations. Finally, we show that nondeterminism can also be expressed using delimited continuations.

Exception Handling

Cubical type theory for dummies

I think I’ve figured out most parts of the cubical type theory papers; I’m going to take a shot to explain it informally in the format of Q&As. I prefer using syntax or terminologies that fit better rather than the more standard ones.

Q: What is cubical type theory?

A: It’s a type theory giving homotopy type theory its computational meaning.

Q: What is homotopy type theory then?

A: It’s traditional type theory (which refers to Martin-Löf type theory in this Q&A) augmented with higher inductive types and the univalence axiom.
