> When the number of "moving parts" created by your abstractions outnumbers the actual bits its abstracting, then you know your design took the wrong turn somewhere.

This is an interesting point which I agree with and is usually where I end up. In the past I've started from the opposite end, creating multiple modules, class hierarchies, etc. This future proofing has made things harder for me to follow/understand when reading at a later date. It has become tiresome and now I consciously start at the other end, making the simplest thing that could work. Layers of abstraction then come naturally as needed.

Part of the zen of Python is "Flat is better than nested". Until recently, I always thought of this at a code block/function level. Recently I realized that this is also important when modularizing and adding layers of abstraction. The more layers of abstraction (from foo.bar.baz import Baz) you add, the more code you write and have to "keep in your mind". This presentation by Jack Diederich at PyCon 2012 really opened my eyes to the potential problems of adding layers of abstraction via modules and classes: http://pyvideo.org/video/880/stop-writing-classes

I needed this in a rake task under Rails 2 a while back; I ended up doing the following:

  require 'action_controller/integration'
  app = ActionController::Integration::Session.new

  module CurrentUserHack
    def current_user 
      @user ||= User.look_up_my_user_here
    end
  end
  ApplicationController.send :include, CurrentUserHack

Now you can make authenticated requests in rake tasks and presumably in script/runner.

I am genuinely surprised at how much others spend on software. I started totaling up his list (excluding monthly services like dropbox) and stopped when I reached $500, which was right around Cornerstone.

You down voted my question but still did not provide a concrete example.

> Money moving from one place to another does not always help the economy. When money flows from the corporate coffers directly into the private accounts of its executives, generally little of that money actually flows into the greater economy.

Can you give an example of how this would hurt the economy?

EDIT - those that down voted, mind giving a reason?

When I first looked at Haskell, the 'Maybe' concept was new to me and seemed like a useful concept for other languages. http://haskell.org/ghc/docs/6.12.2/html/libraries/base-4.2.0...

I agree that the change will cause a lot of pain, however early adopters tend to have a high tolerance for pain. If you don't want to deal with the pain or are running a server (your EC2 mention sounds like a server), you probably want to avoid cutting edge distros like Fedora.

Check out Mondrian: http://mondrian.pentaho.com/ I used it a couple years back at a startup. It's written in Java and IIRC works (only?) with MySQL. Mondrian took a bit of work to get setup, mostly due to my lack of OLAP knowledge at the time, but once setup, it was pretty nice and fast. I think it uses materialized views for the cube data. I'm actually working on a new project where an OLAP will be nice. Thanks for posting Brewery, I'll definitely give it a spin. OLAP's don't get much love, but are very useful for certain types of problems.

In all fairness, the guy was being a dick (no pun intended) to Zed. However, Zed should have kept the insults to the troll and left Github, Powerset, Engine Yard, and the Ruby community out.

Looks interesting, however I really dislike iTunes' "everything under then sun" motto. If you are looking for something much more lightweight for playing music, check out mpd http://mpd.wikia.com/wiki/Music_Player_Daemon_Wiki . There is a really nice Mac mpd client called Theremin: http://theremin.sigterm.eu/

The girlfriend mentions seemed irrelevant and out of place. I've noticed lately that more and more technical bloggers try to inject this fictional writing style to draw in readers. Most of the time it's so out of place that I immediately stop reading. My preference though is terse articles for technical discussions.

Although not as featureful as pv, try hitting CTRL+t under OS X or any of the BSDs during a long running process. It provides status of the current running process without having to prefix the command with pv. I blogged about this a while back: http://jz.posterous.com/bsd-tip-of-the-day-ctrl-t

I purchased my first CD set yesterday. They provide great tools (OpenSSH, tmux, and of course OpenBSD) which save me time and money and make my life easier.

I work remotely 100% of the time (and not always in the same location). The use case for me is to quickly show a feature to coworkers without having to commit/push to a remote server. Especially if the feature needs immediate feedback and is not completely baked/finished.

I saw Aaron Patterson's presentation at RubyConf this year, which I have to say was just as funny as informative. It was essentially all about squeezing every bit of performance out of ARel. He ended up rewriting a good portion of ARel as well. If anyone is interested, the ticket with benchmarking stats can be viewed here: https://rails.lighthouseapp.com/projects/8994/tickets/5098-r...

A little late to the party, but I went through a bout with wrist/arm pain for over a year. I did physical therapy for more than 6 months, saw a doctor that said I needed to have surgery on my arms, neither helped (did not have surgery BTW). I then finally saw a myofascial specialist. She identified the cause of my pain from trigger points in my upper back and shoulders. After just one visit and a follow up visit a year later, I've been relatively pian free. She basically taught me how to address the trigger points my self using a tennis ball and 'The Trigger Point Therapy Workbook' http://www.amazon.com/Trigger-Point-Therapy-Workbook-Self-Tr...

I'd definitely give this book a try since it clearly identifies which trigger points are causing the referred pain/numbness along with the ways to treat them.

Also if you are in the Chicago area, check out http://www.myopain.com/. Like I said, they were able to help me with only 2 visits.

If you work for any employer that actually cares about you, convince them to keep you on their insurance and take a 6 month sabbatical. If they are not sympathetic to your situation, quit your job immediately since they have no regard for your well being. Try the bag and see how it goes. Make friends, travel, enjoy life. Do the things you always wanted to do. Then reassess in 6 months.

Looking at my own life the things that I feel blessed for, have nothing to do with work. After falling in love and starting a family, being rich and changing the world are no longer important. As long as I can provide for my family and raise my children in a way that would make me proud, nothing else matters.

Unplug and try the bag. There is much more to life than business success and $.

I thought the exact opposite. I'm in Chicago and the spill covers a 1/3 to 1/2 of Lake Michigan. After zooming out though, it clearly would cover Lake Erie or Lake Ontario. The thing that was put in perspective for me was the shear size of the Atlantic.
