# Fixed ownership and mode

Notes on teaching both test/unit and RSpec to new Ruby developers

@tenderlove asked "Is it good to teach RSpec (vs t/u) to people who are totally new to Ruby?" I have experience suggesting that it is a good thing; after a short back and forth, it seemed useful to write it up in detail.

Background

This goes back several years, to when I was the primary Ruby/Rails trainer for Relevance from 2006-2009. I'm guessing that worked out to probably 6-8 classes a year during those years. Since then, RSpec has changed a fair amount (with the addition of expect) and test/unit has changed radically (it has an entirely new implementation, minitest, that avoids some of the inconsistencies that made test/unit a bit confusing during the time I'm writing about here).

I started out as an RSpec skeptic. I've never been afraid of what a lot of people denigrate as "magic" in Ruby libraries … to me, if you take the trouble to understand it, that stuff's just pr

One of the first things someone new to iOS Development finds is that dealing with the keyboard is trickier
than they think it should be. Simply changing the scrolling extents of a UITableView (or UIScrollView, or 
UICollectionView) that is partially covered by they keyboard reveals a lot about the internals of how iOS
works and highlights various "gotchas" that need to be considered.

There are various ways to know that a keyboard has been shown - but observing some specific notifications
provides a reliable way to allow you to modify your views to deal with it.

How to set up stress-free SSL on an OS X development machine

One of the best ways to reduce complexity (read: stress) in web development is to minimize the differences between your development and production environments. After being frustrated by attempts to unify the approach to SSL on my local machine and in production, I searched for a workflow that would make the protocol invisible to me between all environments.

Most workflows make the following compromises:

• Use HTTPS in production but HTTP locally. This is annoying because it makes the environments inconsistent, and the protocol choices leak up into the stack. For example, your web application needs to understand the underlying protocol when using the secure flag for cookies. If you don't get this right, your HTTP development server won't be able to read the cookies it writes, or worse, your HTTPS production server could pass sensitive cookies over an insecure connection.

• Use production SSL certificates locally. This is annoying
