Bye-bye Apple
I thought I'd post a brief email I sent to apple this morning, here it is:
I'm emailing to voice my disgust at Apple for not coming out against the stop online piracy act.
Apple, you make my favorite computers, and I use your computers primarily to interact with the world via a free and open internet. If you and other big players don't step up in a barking rage against such a horrible thing as SOPA then I'm afraid free speech online may soon come to an end; It feels like it's heading that way.
I've been dedicated to Apple computers for many years; I'm even a former employee, but it saddens me to say there is a very high chance that my next computer will not be a mac. As much as I like your hardware, I don't believe I can morally support you anymore.

Unable to follow anyone on Twitter
When I follow any user on twitter, they will be removed from my following list automatically withing a few seconds to a few hours.
I can't figure this out. I can change my password and it still happens. I revoked all third party app access. I think it's their system
If anyone has any ideas please let me know. UPDATE: One of my emails to twitter finally got read and they fixed my account.

No Ruby bindings for Xapian installed
I recently upgraded ruby 1.8.7 to patch 330 via rvm and I started getting the error "No Ruby bindings for Xapian installed".
So I'm guessing the ruby bindings are specific to the ruby version, down to patchlevel...?
Resolved by first uninstalling xapian
and then re-installing with the --ruby flag set again

Fresh mac rails development setup - quick and clean

UI for Editing serialized ruby Hash stored in database
For one part of a new project of mine I have decided to store lots of data in a hash stored in a database column. Of course I employed this in my model, I needed a way for a user to edit this hash and save it back out to the database. I drew this up on the board today, and so far, in a very short amount of time, I finished how to output the serialized nested Hash.
Here's my logic that implements nested looping partials, only escaping the loop when the item is a string and not another hash. This provided for output of an infinitely nested hash.
And here's the output with a single record I just threw in there:(ignore the style, it's some inline css that took me 5 seconds to write)
Now I will be making this editable, (new key/value pairs, new hashes...) at whatever depth I see necessary for this order data.
I will update this post tomorrow with how I accomplished this.

Building a google news sitemap with Rails and XML Builder
I was recently tasked with creating a google news sitemap for our main websites
See google's formatting instructions here:
http://www.google.com/support/news_pub/bin/answer.py?hl=en&answer=74288
This was my first time creating an xml output with rails/builder from scratch, so I'm documenting my experience.
oh yeah, this is an older rails app, version 2.0.2
I found a lot of documentation online about builder and creating the tags, but there is NO documentation anywhere about how to create tags with namespaces. I even looked through my massive collection of ebooks. NOTHING!
So I banged my head on my desk for a few hours(metaphorically), and stumbled upon the syntax by chance.
I really hope this helps someone in the future, because I would have paid actual money to someone for this information.
here's my rails {template}.xml.builder syntax I'm using to generate the proper google news sitemap:(sorry about the indenting, bloggers system screws up this post if I try to use the PRE tag to retain whitespace)

RVM on Ubuntu 10.04
I'm beginning the coding phase on a new project. A few days ago rails 3.0.0 was released. I'm going to hop on that bandwagon. And I've decided i'm going to install ruby 1.9.2.
During the obligatory google'ing I discovered RVM: Ruby Version Manager, and I particularly liked this blog post in which contains the phrase "...let’s move the fuck on people, the first preview of 1.8 was released in 2002, and 1.9 has been here for three years!"
I couldn't agree more with his thoughts on 1.9, especially since it's supposed to be MUCH faster. I remember watching a video of Matz last year speaking in his horribly broken engrish about 1.9. I recall him saying how 1.9 fixed many/all of the fundamental logic flaws in 1.8x. Logic flaws? That sounds like something I want to get away from anyway.
So here I go, Documenting what I did to get RVM up and running on my main development box(Ubuntu 10.04).
you'll need some of this:
and this:
and:
NOTE: RVM is ruby code itself, so you'll need ruby and rubygems already installed(if you're reading this I'm sure this is already the case)
then i ran:
and this is what it spit out:
OK looks good so far, i ran
like it told me to and got this huge output:
Ok, so it's warning me about the return statement, I must admit I don't know exactly what this means, so I'll follow the instructions verbatim.
I actually added the:
to the bottom of my ~/.profile file (which is linked from ~/.bashrc)
then I refreshed my bash profile settings with this command:
And now when i run
I get what looks like the usage manual, ok, looking good so far(I think), Now I wanna get me some 1.9.2
spit out:
Awesome, I feel the end is near.
Woo, it's done and it worked:

Dont forget about gems:
Gem Management with RVM
RVM has “gemsets” which allow you to organize different sets of gems. If you install gems into the global gemset, then it will be available to you no matter which gemset you are using.
Create the global gemset.
Install gems here that will be used in projects like bundler and passenger.
Notice that I never use sudo because rvm puts these gemsets in your user ~/.rvm directory.
Now create and use your project gemset.
Obviously YOUR_GEMSET can be anything you want. Then you are set to go!

Eric Young,
Thank you for using rvm. I hope that it makes your work easier and more enjoyable.
If you have any questions, issues and/or ideas for improvement please hop in #rvm on irc.freenode.net and let me know.
My irc nickname is 'wayneeseguin' and I hang out from ~09:00-17:00EST and again from ~21:00EST-~00:00EST.
If I do not respond right away, please hang around after asking your question, I will respond as soon as I am back.
Be sure to get head often as rvm development happens fast, you can do this by running 'rvm update --head'.
w⦿‿⦿t!
~ Wayne
You must now finish the install manually:
1) Place the folowing line at the end of your shell's loading files(.bashrc or .bash_profile for bash and .zshrc for zsh), after all path/variable settings:
[[ -s $HOME/.rvm/scripts/rvm ]] && source $HOME/.rvm/scripts/rvm
Please note that this must only occur once - so, you only need to add it the first time you install rvm.
2) Ensure that there is no 'return' from inside the .bashrc file. (otherwise rvm will be prevented from working properly).
This means that if you see '[ -z "$PS1" ] && return' then you must change this line to:
if [[ -n "$PS1" ]] ; then
... original content that was below the && return line ...
fi # <= be sure to close the if.
#EOF .bashrc
Be absolutely *sure* to REMOVE the '&& return'.
If you wish to DRY up your config you can 'source ~/.bashrc' at the bottom of your .bash_profile.
placing all non-interactive items in the .bashrc, including the 'source' line above
3) Then CLOSE THIS SHELL and open a new one in order to use rvm.
WARNING: you have a 'return' statement in your .bashrc, likely this will cause untold havoc.
This means that if you see '[ -z "$PS1" ] && return' then you must change this line to:
if [[ -n "$PS1" ]] ; then
... original content that was below the && return line ...
fi # <= be sure to close the if.
#EOF .bashrc
Even if you use zsh you should still adjust the .bashrc as above.
If you have any questions about this please visit #rvm on irc.freenode.net.
Installation of RVM to /home/eric/.rvm/ is complete.
Ok, so it's warning me about the return statement, I must admit I don't know exactly what this means, so I'll follow the instructions verbatim.
I actually added the:
