Erlang hash-dos review.

TLDR. It's easy to generate collisions for phash and phash2 when hashing binaries. Erlang dict uses phash so if its possible to generate quadratic slow down by triggering collisions. ETS uses phash2 so its possible to generate quadratic slow down by triggering collisions in ETS. The good news is that even though erlang maps uses phash2 and its possible to generate collisions it does not seem easy to trigger a quadratic slow down because the hash array mapped trie implementation rehashes the input with a different prefix when it can't find a unique position in the trie and it looks like it is difficult to generate inputs that collide over multiple different prefixes.

This review is going to focus on taking the hash of binaries because this is the most likely user controllable input to the hash functions.

Programming as Theory Building

Peter Naur

Peter Naur's classic 1985 essay "Programming as Theory Building" argues that a program is not its source code. A program is a shared mental construct (he uses the word theory) that lives in the minds of the people who work on it. If you lose the people, you lose the program. The code is merely a written representation of the program, and it's lossy, so you can't reconstruct

/*
 * Inspired by Dan Abramov's "Making setInterval Declarative with React Hooks",
 * this is a custom hook for debouncing a callback (e.g. for click handlers) such
 * that a callback will not be fired until some delay has passed since the last click.
 * The callback will automatically be updated with the latest props and state on every
 * render meaning that users don't need to worry about stale information being used.
 *
 * See https://overreacted.io/making-setinterval-declarative-with-react-hooks/ for the
 * original inspiration.

• Nodes - Server, laptop, EC2 Instance, droplet. Whatever can host a docker container. They run your pods.
• Pods - Group of 1 or more docker containers that should be run together. E.g.: an ‘app’ pod may be composed of a NGiNX server, rails app, and a memcached instance.
  • stateless
  • base unit of containerized workloads
  • shared networking space / IP / Port space
  • communicate via localhost
  • share volumes
  • should rarely be created manually
  • kinda feels like a docker-compose file
• Services - By default, pods are not exposed outside of your cluster. Services expose pods to the public internet.

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

• The link in the table of content jumps at the copy of the answer on this page.
• The link on the answer itself points back at the original post.
