That is satire, not an actual response from Peter Moore, although it's not far off from his actual response to the tournament which can be found here: http://www.ea.com/news/we-can-do-better
I would have had a lot of respect for him if he actually released that satirical response although it would not have been very professional. The popular summary of his actual letter is "EA blames worst company win on homophobia"
The book "Starting Strength" by Mark Rippetoe (book and author pretty much universally lauded by the strength training community) is also a great starting point.
Beginners can often become overwhelmed by all the differing viewpoints and training methods presented to them when researching strength training but (besides avoiding injury by maintaining proper form and generally listening to your body to allow sufficient recovery time) the most important thing by far in anyone's fitness lifestyle is simply consistency in actually working out.
I can't comment on stretching but I've found foam rolling (or other such myofascial release) to be the greatest thing ever for relieving tight muscles. Have you tried that?
I should note that I was doing these things before I read the article but this post helps to reassure me that I'm on the right track. I glanced at the article about learning Rails and also found the RailsTutorial book to be a great resource even for a beginner like myself given its "dive in and start doing realistic projects" nature.
I rolled my eyes when I read the title expecting another compendium of codeacademy-like resources which get you started and then leave you out to dry. I'm finally beginning to feel like I'm actually learning to code by doing pretty much exactly what you described!
I had a feeling of coziness and was reminded of human cohesion looking at what I presumed to be millions of people coming together to sleep at the same time preparing for the next day. It seemed so peaceful.
