Using Mailboxes in Elm

Max Goldstein | July 30, 2015 | Elm 0.15.1

In Elm, signals always have a data source associated with them. Window.dimensions is exactly what you think it is, and you can't send your own events on it. You can derive your own signals from these primitives using map, filter, and merge, but the timing of events is beyond your control.

This becomes a problem when you try to add UI elements. We want to be able to add checkboxes and dropdown menus, and to receive the current state of these elements as a signal. So how do we do that?

Haskell Style Guide for Elm

Goal: a consistent style throughout all Elm projects that is easy to read and produces clean diffs to make debugging easier. This means valuing regularity and simplicity over cleverness.

Line Length

Keep it under 80 characters. Going over is not the end of the world, but consider refactoring before you decide a line really must be longer.

ECMAScript 6

Introduction

ECMAScript 6 is the upcoming version of the ECMAScript standard. This standard is targetting ratifcation in December 2014. ES6 is a significant update to the language, and the first update to the language since ES5 was standardized in 2009. Implementation of these features in major JavaScript engines is underway now.

See the draft ES6 standard for full specification of the ECMAScript 6 language.

ES6 includes the following new features:

Wireshark is an awesome tool especially for debugging HTTP requests done by small embedded devices. Typically the developers of http libraries on these platforms typically develop a very minimal subset of the protocol for their use case.

Debugging any compatabilty issues can be a pain in the butt, this is where wireshark comes in. It enables to look at what was transmitted across the wire and with a few rules pick up anomolies.

I have put together a few handy recipes.

This one is a brief summary of the HTTP requests.

sudo tshark -d tcp.port==8080,http -R 'http.request or http.response' -i lo0 ip and port 8080
