Phew. Day #3 felt a bit hectic.

Day #2

The task for today was:

Today, I want you to start. It doesn’t matter if you feel ready. Start.

RepoReader was already a work in progress before I joined Week of hustle so it was all about pushing it harder than before. Instead of slacking off I did manage to accomplish quite a lot today.

JFDI

I’ve been a part of an online community called JFDI. It’s a community for solo-founders, bootstrappers or anyone launching their own thing. Also JFDI stands for “Just Fucking Do It” so that should explain the whole deal behind it :)

Week of hustle

It’s a week long event (8 days to be more precise) organized by JFDI in which you work hard to push out a new product, finish an existing one or whatever. Simply put – a kick in the butt to get things done and it’s just what I needed so I’m taking a part in this event.

What do you do in Ruby when you need to get a count of elements in an array? You use methods like count, size or length. Ok, but do you know what’s the difference between those methods? I’m not talking about Rails and ActiveRecord and the different approaches each of these methods take to return a count. I’m talking about plain old Ruby.

I thought I understood the route/template nesting in Ember.js well enough until I recently did a pair programing session with Matthew Lehner. Turns out I missed an important thing about nesting.

In Ember.js there is this feature called computed properties. You can learn more about what computed properties are in the official Ember.js guides. Instead I wanted to talk about how they act depending on what you pass to .property().

Recently I fixed an issue related to html_safe/unsafe string concatenation in RefineryCMS’ Blog extension and learned a lesson (again) that I should read docs more carefuly instead of just scanning them vaguely (I tend to do that).

This is an explanation/reminder post about how to whitelist HTML tags and their attributes in the WYSIWYG editor called WYMeditor which is used by Refinery CMS.

I assume you have a running Refinery CMS v2.x.x application!

Lets start by opening config/initializers/refinery/core.rb and looking for a config option called wymeditor_whitelist_tags:

1
2

# Add extra tags to the wymeditor whitelist e.g. = {'tag' => {'attributes' => {'1' => 'href'}}} or just {'tag' => {}}
# config.wymeditor_whitelist_tags = {}

At first that comment above the config may confuse you but don’t worry about it now.

I’m putting together a Ruby 2.0 talk for a local Ruby meetup group and I thought it wouldn’t hurt to write down what I have learned about Keyword Arguments which is a new feature in Ruby 2.0.

You’ve been using Hash#fetch and are happy with it. You also know that you can specify default return value in case the key you are looking for is not present in hash.

{}.fetch(:test) # => KeyError: key not found: :test

{}.fetch(:test, "test") # => "test"

{}.fetch(:test) { "test" } # => "test"

Lines 3 and 5 return the same result so what’s the difference you may ask? Read on →
