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?

Managing OpenStack instances with Ansible through an SSH bastion host

I'm be using DreamCompute as my OpenStack provider, but there are dozens to choose from. I assume you already have Ansible and the OpenStack CLI tools installed.

Motivation

With the proliferation of OpenStack public clouds offering free and intro tiers, it's becoming very easy to effectively run a simple application for free or nearly free. Also with the emergence of Ansible, you don't need to learn and deploy complicated tools to do configuration management.

How to implement a custom search for Hugo usig Gruntjs and Lunrjs.

Requirements

Install the following tools:

• Nodejs
• Gruntjs

Setup

unbracketed

Example: Moving up to a few commits to another branch

Branch A has commits (X,Y) that also need to be in Branch B. The cherry-pick operations should be done in the same chronological order that the commits appear in Branch A.

cherry-pick does support a range of commits, but if you have merge commits in that range, it gets really complicated

git checkout branch-B
git cherry-pick X
git cherry-pick Y

Rich Hickey on becoming a better developer

Rich Hickey • 3 years ago

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:

Org Editing in haskell-mode

The video opens with a regular Haskell source file in haskell-mode. We start off by adding headings that break the file into meaningful chunks. A section heading is indicated by an asterisk following Haskell single-line comment characters, i.e. -- *. These are top-level headings, sub-headings are indicated by adding more asterisks.

These section markers are given meaning by
