interesting re-cap of Reginald Braithwaite's talk given that he just blogged he's retiring from blogging and ruby hacking.

http://weblog.raganwald.com/2008/07/brief-history-of-dangerous-ideas.html

btw, living in the fringe is where you get to test and hone concepts that become practical technology. It's fun because of the growth you undertake and the opportunity to contribute things. in my opinion.

Alan Brown — Thu, 17 Jul 2008 13:52:28 GMT

Totally agree. I think it makes sense to also make it predictable for doctors what the consequences are for their mistakes, instead of having a jury come up with something.

Even more important is accurate data regarding outcomes for certain procedures NOT reported by doctors themselves but gathered independently.

Also good would be to have some separation from assessment and delivery. Thee is a natural conflict of interest when the person who will be paid to deliver solutions is also decidng whether those solutions are needed. I guess that was the idea initially behind the primary care physician, but something got lost along the way.

Regarding software developers, there are no real liability concerns from admitting mistakes, so only the ego stands in the way.

Not comparable at all to the back surgeon acknowledging, "Oh yeah, looks like this surgery has left you with even more pain. Sorry about that. Have a nice life."

Hi, class Book class Author...

Advait — Fri, 11 Jul 2008 03:57:38 GMT

Hi,

class Book < ActiveRecord::Base belongs_to :author end

class Author < ActiveRecord::Base has_many :books end

And I am using

before_filter :abc def abc @author = Author.find(params[:author_id]) end

I am getting an error "Couldn't find Author without an ID"

How do I correct this as I have no idea about this

Anyone have any instructions for Merb and/or Rack handlers?

In my first attempts to use this library I tried to wrap the call in a begin/rescue block. I wanted to explicitly rescue Timeout::Error so I could return a 504 Gateway Timeout error to the client. However I seem to be unable to rescue the exception.

Thanks! This took some guess work out of my work. Interesting idea about writing a generator. Maybe I'll get to that someday.

This is why I wish Heckle was a little more robust/well-used. It seems like it would be a great boon to the test-driven workflow, if only it weren't so finicky.

Adam Wiggins — Mon, 07 Jul 2008 20:19:05 GMT

@marktucks - There are a lot of diverse opinions on the best way to write specs/tests, what framework to use, etc. I blog about this quite often, as you can tell: http://adam.blog.heroku.com/past/tags/bdd Reading through these should answer some of your questions, at least from one person's perspective.

Some other Ruby-centric resources on the subject I recommend:

marktucks — Mon, 07 Jul 2008 18:32:02 GMT

Is RSpec the de facto test framework i.e. what everyone is using, like Git?

Also, are there any really comprehensive test tutorials, including things like what to test, how to test, code coverage etc?

Thanks.

JS — Mon, 07 Jul 2008 15:39:43 GMT

Harlan Mills at IBM worked on useful methods of software engineering called "cleanroom software engineering". By the mid-70s they basically worked out how to build software that is provably correct by design at no additional cost beyond conventional software development methods. Comparing that to the present day methods of programming, we've regressed considerably in the last 30 years across most of the industry. More info can be found here if you're interested: http://www.sei.cmu.edu/str/descriptions/cleanroom.html

"Nearly all developers, myself included, spend most of our time in that state: not quite trusting that the code all works"

Fantastic quote. In ten years of development, no matter how amazing the code, or tests, this is our state of mind. I'm always amazed when things work the first time.

ngvrnd — Mon, 07 Jul 2008 09:46:39 GMT

If a bug is a variance from spec, and the behavior you observed was from code which wasn't spec'd, was it a bug? Maybe an additional definition is needed; any code which isn't covered by the spec is also a bug.

Ohh and THANK YOU for havinf formulating this : "Nearly all developers, myself included, spend most of our time in that state: not quite trusting that the code all works.". That's SO TRUE (IMHO too, at least)!

Adam Wiggins — Mon, 07 Jul 2008 04:29:27 GMT

Thanks guys. I thought this post would be more controversial - glad to hear I'm not alone on this. :)

Now, playing devil's advocate to myself here, specs can only extend so far - i.e. to the edges of the component they belong to. In a service architecture there's still the interaction between components. I'm starting to develop some techniques to cover that, but it's a very different sort of thing. No doubt I'll post about that stuff at some point.

Absolutely! This is why debugger support is a bad thing. Development practices which are very close to bug-proof exist.

Although I've been a TDD supporter for years, I hadn't yet learned BDD. I've been thinking its something I should do, and now I'm convinced. Thanks.
