Comment on Direct Manipulation, and Text Editors by jpmccusker

I use the AquaMacs Emacs variant, which neatly combines mac UI conventions and shortcuts (using the command key) and conventional emacs ones (using option for meta and control for control). I mix and match the UI conventions as they occur to me, having more than one means I have larger targets to hit, in a sense.

Comment on Ruby’s other ternary operator by Daniel Bernier

I don’t know which is faster, but I doubt it’s an order-of-magnitude difference. This was an article about language expressivity, not performance, so I didn’t worry about it.

So, what is the code that runs the fastest? How was this tested out?

Ah, I see. I got the associativity wrong. Thanks.

…and hey, we’ve ALL got a lot to learn. :)

No, I meant to use assignment (=), not equality testing (==). The effect I was after was to set a to “a”, and b to “b”.

Here are some parentheses to clarify:
a = (true ? ‘a’ : ‘b’) #=> “a”
b = (false ? ‘a’ : ‘b’) #=> “b”

Does that help?

I confess I’m not too proficient with Ruby, but isn’t your ternary example wrong? I think you’re missing a couple “=” and they should be written like this:

a == true ? ‘a’ : ‘b’ #=> “a”
b == false ? ‘a’ : ‘b’ #=> “b”

Of course I fully expect to be told why I’m wrong and how much I still have to learn :)

Comment on Chaos, Order, and Software Development by Dave Silveira

Hey Dan,

Nice post. Reminds of the system we worked on, and the one I am “blessed with” now.

Business types want us to build things as fast as possible. Well meaning developers who don’t know any better build systems that eventually become so rigid and fragile they can no longer provide business value effectively. Nobody was thinking about the big picture, just getting the feature out the door and getting the next client.

Comment on What Indians call the ‘@’ symbol by yosh

I’m Indian and I just spent 6 months in India after many years away and I must have heard “adderate” a billion times on my trip. It was fascinating to hear, but ultimately quite annoying. I do wish people would just say “at” or “at sign”.

Comment on Out of Love with Active Record by Sheldon Hearn

Thank you. You’ve validated both the sense of dread I feel when I consider moving beyond Active Record, and the sense of hope I feel about the potential results.

Here’s where I’m at with this:
