For a safe and fast Erlang SSL server, there's a few 
configuration values you might want by default:

    [{ciphers, CipherList},      % see below
     {honor_cipher_order, true}, % pick the server-defined order of ciphers
     {secure_renegotiate, true}, % prevent renegotiation hijacks
     {client_renegotiation, false}, % prevent clients DoSing w/ renegs
     {versions, ['tlsv1.2', 'tlsv1.1']}, % add tlsv1 if you must

Pony Considerations

If you're thinking of checking out the Pony programming language, here's a list of things that I think are important to know. This list is based on a Tweet that I wrote.

Editor/IDE support

There are Pony packages for several popular editors.

• Emacs
• Sublime

1) Read an image from file
2) Display an image that you read from file
3) Capture Video using your webcam and display the feed
4) Display back and white live stream from your webcam.
5) Have a slider to change brightness of the webcam live stream. Display.
6) Have a slider to change contrast of the webcam live stream. Display.
7) Capture a snapshot from your webcam. Then display difference between live video stream and this snapshot. (Background subtraction)
8) Display Canny edge image from your live webcam stream
9) Have a slider to change smoothness / sharpness of image from live webcam stream.
10) Display histogram of colors (RGB) from your live webcam stream

Nixpkgs pinning example

This is an example of how to pin the version of nixpkgs in a package repo. The goal is to improve reproducibility, make sure all the developers use the same version of nixpkgs and also allow to share binary caches.

Usage

Put all these files in a nixpkgs folder and then in other derivations, instead of import <nixpkgs> {} use import ./path/to/nixpkgs {}

Keeping nixpkgs up to date

If you want a run-down of the 1.3 changes and the design decisions behidn those changes, check out the LonestarElixir Phoenix 1.3 keynote: https://www.youtube.com/watch?v=tMO28ar0lW8

To use the new phx.new project generator, you can install the archive with the following command:

$ mix archive.install https://github.com/phoenixframework/archives/raw/master/phx_new.ez

Bump your phoenix dep

Phoenix v1.3.0 is a backwards compatible release with v1.2.x. To upgrade your existing 1.2.x project, simply bump your phoenix dependency in mix.exs:

mrkgnao

module Main

import Data.Vect

-- %hide transpose

dot : Num a => Vect n a -> Vect n a -> a
dot va vb = foldr (+) 0 $ zipWith (*) va vb

Matrix : (rows : Nat) -> (cols : Nat) -> Type -> Type

# unregister broken GHC packages. Run this a few times to resolve dependency rot in installed packages.
# ghc-pkg-clean -f cabal/dev/packages*.conf also works.
function ghc-pkg-clean() {
  for p in `ghc-pkg check $* 2>&1  | grep problems | awk '{print $6}' | sed -e 's/:$//'`
  do
    echo unregistering $p; ghc-pkg $* unregister $p
  done
}

# remove all installed GHC/cabal packages, leaving ~/.cabal binaries and docs in place.
