Keep reading and watching videos, but cut that time down in half and use the rest of the time for exploring codebases and writing code of your own. If you do a code reading exercise, make sure you have the code open in your editor, and that you're able to interact with it via a REPL, its tests, etc.

Then from there, I'd recommend starting with very small, tiny projects. Ideally your first one should be something so simple you can do it in an hour or two.

Gradually work your way up from those tiny projects to slightly bigger ones. So start with one that takes an hour or two, then move up to one that might take 5-10 hours, then one that might take 20 hours, then 40 hours, etc. It's OK to stop at the size where you're feeling you're getting the most learning benefit.

Each time you try a new project, make it realistic if you can, but don't worry too much if you'll actually use it. The value is in having a rich context to try out ideas, not in the actual utility of whatever you build.

For each project you wor

I think you might benefit from a detailed study plan when you're a little further along with your studies. For now, I'd recommend following your interests, and taking a project-based approach towards learning.

Start with an idea of something you might want to build, and then make a list of all the stuff you'd need to learn to build it. Then, strip down the idea to make it a little more simple, and redo the list. Keep doing that until you have a list that's small enough to manage

Fair warning: full-scale applications tend to look like "first invent the whole world, then build your app", so you may need to come up with really simple ideas to start on. That's OK! You may also not know what you need to know until you try building things, that's OK too.

Once you have a few ideas, start reading and watching videos related to the technical tools and concepts you need. But only go just as deep into those resources as you need in order to build one small piece of a real project... you can always come back later i

In Rails 2, if you wanted to define a named date/time format, the conventional way was to make an initializer which would modify the DATE_FORMATS hash that ActiveSupport mixed into Date and Time:

# config/initializers/date_and_time_formats.rb
def military_hour_to_civil_hour(hour)
  mod = (hour % 12)
  mod + (12 * (mod > 0 ? 0 : 1))
end

Date::DATE_FORMATS[:std] = lambda {|d| "#{d.month}/#{d.day}/#{d.year}" }

I want to get off Gmail for two reasons:

1. my own *@mislav.net address
2. to get my email under my own control so I can write scripts to process/analyze it

I've asked on Twitter what software should I use.
Here are the aggregated suggestions.

Why is the server unhappy?

• Bundle API is 70%-80% of traffic and it has to resolve the dependency graph and Marshal
• x Processes are spinning in Ruby with 380% (of 400% total CPU [4 x 100%])
• x Bundle can only use vanilla gems, so that's why we have to use Marshal
• Redis Heapsize
• Diskspace
