Browserstack

My setup for configuring a Rails app with RSpec Feature tests that uses Capabara to test on a browserstack remote browser.

The browserstack docs only show either an RSpec or a Capabara setup.

What I wanted:

In development run my tests quickly with poltergiest.
Run nightly builds on CI to test against different web browsers using browserstack.
Have the option to visually run my tests with selenium with Chrome, Firefox etc.

rename a section of a filename, i. e. example.1.{txt,conf,db} or 12345.1.{wav,ogg,mp3} and

change the 1 to a 2 in the filename while preserving the rest of it.

$ zmv -n '(.)(<->)(.[^.]#)' '$1$(($2+1))$3' # would rename x.0001.y to x.2.y. $ zmv -n '(.0#)(<->)(.[^.]#)' '$1$(($2+1))$3'

Rename files to lower case

$ zmv '*' '${(L)f}'

serially all files (foo.foo > 1.foo, fnord.foo > 2.foo, ..)

$ autoload zmv

Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.

Setup

installation, Ubuntu

This post is also on my blog, since Gist doesn't support @ notifications.

Components are taking center stage in Ember 2.0. Here are some things you can do today to make the transition as smooth as possible:

Use Ember CLI
In general, replace views + controllers with components
Only use controllers at the top-level for receiving data from the route, and use Ember.Controller instead of Ember.ArrayController or Ember.ObjectController
Fetch data in your route, and set it as normal properties on your top-level controller. Export an Ember.Controller, otherwise a proxy will be generated. You can use Ember.RSVP.hash to simulate setting normal props on your controller.

1. Install tmux + tmuxinator

gem install tmuxinator

2. Add ~/.tmuxinator project specific configurations

# File: ~/.tmuxinator/project-name.yml

name: project-name

Git-workflow vs feature branching

When working with Git, there are two prevailing workflows are Git workflow and feature branches. IMHO, being more of a subscriber to continuous integration, I feel that the feature branch workflow is better suited, and the focus of this article.

If you are new to Git and Git-workflows, I suggest reading the atlassian.com Git Workflow article in addition to this as there is more detail there than presented here.

I admit, using Bash in the command line with the standard configuration leaves a bit to be desired when it comes to awareness of state. A tool that I suggest using follows these instructions on setting up GIT Bash autocompletion. This tool will assist you to better visualize the state of a branc
