Do you use video taping to your advantage?
I recently videotaped myself and a self-defense pro for my latest educational web site.
While the content of the video was fine, I was pretty nauseated at how I looked. Aside from the weight I’ve gained in the past two years, my facial expressions were stiffer than Al Gore’s. Painful though the experience of watching this video was, I learned a lot about how to improve my facial expressions – starting with relaxing and smiling more in front of others. I used to be good at that, but not on this day.
Anyway, it’s a great idea to get yourself videotaped once in a while, to see how you come across to others. You might be surprised to find that your intent (come across as a brilliant, happy, enthusiastic person) doesn not match your impact.

Insta-block with Symbol#to_proc
Something that might have slipped your radar in your Ruby readings is Symbol#to_proc, something that’s been in Rails since 0.14.4.
Using this nice little tidbit of Ruby tricky you can simplify code such as:
articles.collect { |a| a.title }
articles.sort { |a| a.created_at }
to
articles.collect(&:title)
articles.sort(&:created_at)
…and just in case you’re wondering why &:ruby_is_the_new_black doesn’t work in the beautiful ruby shell script you just wrote, it’s because Symbol#to_proc isn’t a standard Ruby thang. To quote Mauricio Fernandez who noted it’s recent inclusion in the upcoming Ruby 1.9:
Symbol#to_proc: first discovered by some anonymous Japanese Rubyist (fairly certain), rediscovered by Florian Groß (I saw that happen back when I wasted my time on #ruby-lang), then popula rized by Pragdave and Rails, finally adopted officially. It’s been a long journey.
“That’s nice,” you say, “but I still don’t really understand what all this Proc and block stuff is about.” Well, let me indulge you in some Ruby block mumblings.
I think the best way to describe a block if you’ve come from web-design-land is to think of it like an anonymous function in Javascript.
For example, the following piece of Ruby:
socceroos.each do |s|
s.congratulate
end
is the equivalent to the following Javascript:
socceroos.each(function(s) {
s.congratulate();
})
The block passed to …
DRY your Migrations
Use Ruby’s method_missing madness to add some DRY to your ActiveRecord migrations. Rails 1.1 introduced Object#with_options which allows you to remove duplication for method calls with common options, but wouldn’t it be nice if we could use this in migrations too…

Finally a little Railz’d
So finally had a first hand run-in with Rails at last nights webtuesday, thanks to Patrice, based on his experiences of putting together list.blogug.ch.
Was interesting but sadly we didn’t really have enough time with the game starting at 6 – Patrice was able to give us a demo of what Rails (and rake) provides, the selling “Wow!” factor but there wasn’t enough time for much critical questioning, which has become part of what marks webtuesday – there are some very experienced hands attending regularily now, such as Urban, who only had time to question validates_uniqueness_of in regard to full table scans.
The next mission is tracking down some Python developers in Zurich – tip offs appeciated.
A big thanks to Eurospider for hosting it and kindly providing bbq and beer and the live match – couldn’t have been better.
