I attended quite a few talks, grabbed a lot of swag, and entered a few contests. I ended up buying the Arduino Starter Kit from MAKE so I can do some awesome embedded Ruby like I saw at FOSCON. It looks really fun – I can’t wait to try it out.

The talks I attended were half-way decent, but I learned a lot more on the first day.

Hadoop and EC2

A good overview of how one can use Amazon’s S3 and EC2 services to cheaply process and store data on a pretty large scale. The New York Times digitized hundreds of years of articles in a single day using these services and some awesome C++ code.

Open standards in cloud computing

This ended up being a marketing talk. I don’t know what it had to do with cloud computing, and I didn’t stick around to find out.

Ruby 1.9: What to Expect

An awesome overview of all the new stuff in Ruby 1.9 given by Sam Ruby. I had no idea they were changing so much, and this was a good dive with code examples into that. There was some discussion among everyone in the middle on whether for loops should work like .each blocks with regards to scope. I happen to disagree with what ended up being the popular thought on this subject. Most were advocating that a for loop constitutes a block, and that scope variables and iterators should be localized inside of it. This is contrary to almost every language, which I brought up using the example of C. Yet, when you iterate with .each, you immediately define a block and a scoped iterator, which, if it has a conflicting name with the outside world, it doesn’t matter since that’s out of scope. The only thing this changes is the value of a variable outside after the loop finishes. I think leaving the ability to modify a variable external to the loop is very convenient – in summary, leave it how you’ve done it in Ruby 1.9 already.

Ubuntu on the Go: Subnotebook and MID technologies

This was an interesting session on where Canonical is taking mobile technology, and what the community can do to help. They seem to have a pretty neat subnotebook coming out soon.

Python, C++, and SWIG

This could have been one of the best talks, but the speed at which it was given and the lack of enthusiasm in the presentation left most of us either bored or unfulfilled at the end of the talk. He spent the first half explaining what Python and C++ were, then he got to what SWIG is. The end was a quick dive into an extremely complicated bunch of files that didn’t help very much. In the future, it would be helpful to go to a SWIG talk that details how to make a simple Python extension with SWIG. I may have to throw that one together myself…

I also attended the tail end of Designing Political Web Apps for MoveOn.org, but I didn’t take any notes.

We ended up going to dinner at Widmer Brothers, which was pretty awesome. I had the Pork Schnitzel, a very tender piece of meat if I do say so myself, along with 2 Full Nelson IPAs. Afterwards, we caught the bus from the convention center to BeerForge and the SourceForge Community Choice Awards party. Beerforge was a blast. I ended up talking to Jean-Baptiste Kempf, one of the developers of VLC, for hours – a truly great guy. I learned a lot about France and the French people, but also about VLC. Apparently, you can use VLC from the command line much like mplayer, which I did not know. Yet, he explained that they removed Directshow support from VLC in Linux in favor of open source alternatives, which in part I can understand. Yet, the only codec available that is able to smoothly play 1080p h264 video is closed source (CoreAVC), and until the ffmpeg avc codec catches up, I’ll have to continue using mplayer. When I can play everything back smoothly with VLC, I may consider switching.

The beer at BeerForge was pretty good – I had the IPA. SourceForge had some sort of mixed drink which wasn’t too great. All in all, a good day, but now I’m dehydrated…

Today, I got the craving for some beer again. I drove down to Corridor Fine Wines and picked up 49 beers (singles, of course). Here are some photos of the booty:

Now, I just have to slowly and meticulously try and catalog these beers. It’s going to take quite a while. I managed to crack a joint (one of the stiff ones from my recent injury) on the way to my car, and it hurt a lot. Hopefully I didn’t damage anything…

Also, there was a really cool picture of a nuke going off today:

So, after reviewing over 50 beers on BeerAdvocate, I’ve come to the conclusion that them not having an RSS or Atom feed of my most recent reviews available is stupid. So, I decided to make my own by scraping their HTML today. I started off by pumping some random code into irb that included Hpricot and Builder. Ruby rocks for doing stuff like this. Anyway, I ended up with this at the end:

require 'rubygems'
require 'hpricot'
require 'open-uri'
require 'builder'

# Get the document to scrape
doc = Hpricot(open("http://beeradvocate.com/user/beer_reviews?user=ralree"))
trs = (doc/"table")[2].search("tr")

# Create the feed
target = File.new("beer.xml", "w")
xml = Builder::XmlMarkup.new(:target => target, :indent => 1)
xml.instruct!
xml.feed "xmlns" => "http://www.w3.org/2005/Atom" do
  xml.id "http://www.ralree.info/beer.xml"
  xml.title "ralree the BeerAdvocate"
  xml.subtitle "Recent Beer Reviews"
  xml.link  "rel" => "self", "href" => "http://www.ralree.info/beer.xml"
  xml.updated Time.now.iso8601
  xml.author  { xml.name "Erik Gregg"; xml.email "ralree@gmail.com" }

  # For each TR, make an entry
  trs.each do |a|
    tds = a.search("td").to_a
    if tds.length == 7
    xml.entry do
        xml.updated(Time.parse(tds[0].inner_html.gsub('-', '/')).iso8601)
        xml.title((tds[1]/"a/b").inner_html)
        xml.link(:href =>
          ("http://www.beeradvocate.com" + ((tds[1]/"a")[0]["href"]))) do |x|
          xml.text!((tds[1]/"a/b")[0].inner_html)
        end
        xml.summary do |p|
          p.cdata! <<EOOMFG
Brewery: #{(tds[2]/"a")[0].inner_html}
Style: #{(tds[3]/"a")[0].inner_html}
Serving: #{tds[4].inner_html}
ABV: #{tds[5].inner_html}
Rating: #{(tds[6]/"b").inner_html}
EOOMFG
        end
      end
    end
  end
end

This produces the feed that you can find here. Feel free to add it to your aggregator, and you’ll be notified whenever I review a beer! This is what it looks like:

This should make for a fun month.
