No, you're deliberately misunderstanding her. Here's a screenshot of the page in question: http://cl.ly/image/2V302C3j290B I can see how it'd be easy to miss the fact that this will send an email, although it's stated unambiguously, at t

If you're using a third-party payment provider like Authorize.net or Braintree to store CC numbers, you'll be given a unique token from the provider when you add the CC number. When you add the CC you can also have the provider run and imm

They're both wrong. It's a false dichotomy. The best programmers run up and down the ladder of abstraction. The magic happens the marriage of the two.

Hello! I'm one of the co-founders of Dev Bootcamp ( http://devbootcamp.com ). The answer is 100% yes. :) Funny enough, we go over basic data structures (linked lists, stacks, queues, etc.) in the first week at DBC and we emphasize at ever

That makes the comments on the original all the more inane, then.

That's good to know! I assumed from the comments -- most of which were from 2010 and admonished him for not being familiar with the data structure already -- that he was describing something which already existed at the time. Anyhow, man,

He was quoting me quoting Hegel, talking about the relationship between familiarity and understanding. Unfortunately English doesn't have the precise distinction that German does, so the translation is a little confusing. To an English spe

Yes, that's what 90% of the comments on the article said, too. Welcome to the club. :P He's talking about people's everyday understanding of data structures, including his own. That the data structure he described already existed when he

This is a great article and the diagrams illustrating the difference between a binary heap and a B-heap are awesome. The comments are amusingly negative, too. It's worth noting that it was published in 2010, though. The Wikipedia article

I don't buy this. There's something about the article that annoys me, too. I can't quite put my finger on it. I think it's because it has a linkbaity title, a tone of confidence, but is filled with weird stuff. Disclaimer: I co-founded E

Yeah, I'm wondering how it might work if instead of using a sequence of byte configurations in memory it used a sequence of pixel configurations from the screen.

Often, yes, if you have a good relationship with a well-established firm or have someone who does vouch for you. Most top tech law firms (WSGR, Orrick, Fenwick & West, Gunderson Dettmer, etc.) will defer payment or even waive certain f

When a currency is experiencing deflation it makes sense not to spend it. In that world, keeping my money under my mattress is the soundest investment strategy. Why would I buy anything with my bitcoins if a week from now they're going to

Here's my current working hypothesis. The part of the body that learns how to program[1] doesn't speak English. You hear it even in the metaphors programmers use: code smell, this "feels" like a recursive problem, "listen to your code," et

I have a degree in mathematics from the University of Chicago. Want to talk about self-adjoint algebras of compactly supported continuous functions? I'm your man. I also think teaching this using mathematical notation would be a mistake.

I love this comment. It shows how powerful the right metaphor can be in understanding something, which is something we obsess over at Dev Bootcamp when teaching students. It also shows how tiny affordances ( http://en.wikipedia.org/wiki/A

What would be much more interesting than "peak responses per second," which is a weird metric to begin with, is the actual histogram of sampled throughputs. Or at the very least a box-and-whisker plot ( http://en.wikipedia.org/wiki/Box_plo

The data could be coming from multiple places and sources, only some of which are "models." This is true in Rails, too. For the sanity of the view, the controller is the single point where it can get the data. It shouldn't know the nitty

by jfarmer 14y ago
@rob: The controller should be the data as far as the view is concerned. Otherwise the view knows too much and the controller can't re-proxy a different model.

by jfarmer 14y ago
That's not how I'm seeing it. The controller has data, some of which might be from the model. The view shouldn't care whether the data came from a model or not. It would be coupling if the view did care. The view asks the controller fo

I've never used EmberJS and am not familiar with any of the front-end JavaScript frameworks, but I don't get what's confusing. It looks like instead of the controller pushing data to the view, the view asks the controller for data (which it

Stop being sensible, will you? This is exactly how we did things at Everlane ( http://everlane.com ) and Dev Bootcamp ( http://devbootcamp.com ).
