21 August SSH hopping

Friday, August 21st, 2009 - 01:50 pm

Recently, two of the servers I normally SSH into had to be locked down to where they can only be accessed from computers at the main office.  Since I work remotely, this of course has been a bit of a pain.  I’ve had to SSH into a work machine, and then SSH from there.

However, I’ve discovered there is a way to hop with SSH:

Now, I can simply type ssh remote and get to the remote machine. Very handy.

Note: Just for completeness, remember that SSH keys need to be properly configured on the “office” machine in order to connect from “office” to “remote”

19 August ActiveRecord :joins

Wednesday, August 19th, 2009 - 12:20 pm

I didn’t know that the :joins option for ActiveRecord accepted named associations. This works perfectly when you want to join with a table to retrieve information without actually “including” the model. It also makes the query much simpler.

Just be sure to always use :select when using :joins, or joined tables may overwrite attributes primary table in the result (i.e. the id attribute).

14 July Books

Tuesday, July 14th, 2009 - 02:05 pm

My passion for programming outside of work is on an extended hiatus.  I don’t have any good reason to continue working on current projects, so I’ve been using my time for other things.  I’ve been enjoying my journey in the world of books, a passion I once had long ago (~10 years since my high school days, wow…).

So far, I’ve read the following:

  • Fahrenheit 451
  • The Hitchhiker’s Guide to the Galaxy
    • The Restaurant at the End of the Universe
    • Life, the Universe and Everything
    • So Long, and Thanks for All the Fish
  • Neuromancer
  • Count Zero

I tried to read Ender’s Game, but I was so wrapped up in Neuromancer at the time that I had to just return it.  I’ll probably give it another shot soon, though.  Right now, my list of books to read includes:

  • 1984
  • Slaughterhouse-Five
  • The Long Dark Tea-Time of the Soul
  • Mona Lisa Overdrive
  • Foundation Series
  • Dune
  • Brave New World

That’s quite a list, really, especially since the Foundation Series is something like 14 volumes.

19 June Shut up about the gems, Rails

Friday, June 19th, 2009 - 04:48 pm

Add this to config/environment.rb above the Rails::Initializer block:

Rails::VendorGemSourceIndex.silence_spec_warnings = true

Bask in the silence - no more “gem has no specification file” etc.

26 May Switched to Wordpress

Here’s the thing: I simply don’t have enough time/motivation to work on my own blogging application (slate).  Now, I can hopefully focus on the most important piece - the content.  Even if no one reads it.
