How music works, using Ruby

Thijs Cadier says:

That strange phenomenon where air molecules bounce against each other in a way that somehow comforts you, makes you cry, or makes you dance all night: music. Since the advent of recorded audio, a musician doesn't even need to be present anymore for this to happen (which makes putting "I will always love you" on repeat a little less awkward).

Musicians and sound engineers have found many ways of creating music, and making music sound good when played from a record. Some of their methods have become industry staples used on every recording released today.

Let's look at what they do and reproduce some of their methods in Ruby!

Building a Mortgage Lender at Generation Home

André Barbosa says:

It’s not often that you hear about a startup doings things differently in the mortgages world. And there’s some good reasons for it, the cost of entry is super high!

It’s not just funding and regulations either. You also need to back it up with the right technology and tools to manage a highly complex business where mistakes can be very costly. On top of that, startups need to move fast to out-innovate the incumbents with only a fraction of the resources.

At Generation Home Ruby has been a catalyst to help us deliver a product we’re proud of in a short time-scale. We’ll talk about some of the challenges we faced early on, how Ruby, Rails and the whole ecosystem helped us deliver and what still lays ahead of us.

Fixing flaky tests, using RSpec's --seed option

Shen Sat says:

Fixing a flaky test in the build pipeline of your application often requires first replicating the failing test locally. I'm going to show you how I used RSpec's --seed to help me do this for a flaky test I was recently grappling with, and how it led led me to a fix ✨
