If you have a list of thousands of items, attaching event handlers to each of those items separately is relatively expensive, although it makes the view code nicer. If you are as serious about performance as these people, you would want to

This is important to remember but hopefully not relevant. If you have event handlers on each card instead of delegating them to the container, that's a performance problem all by itself.

But note that ruby's symbols are interned, so if you create lots of them programatically they never get GC'd.

It is indeed, and the book I mentioned is the prequel to his book "A Pattern Language." But there is an enormous difference between his real idea of "design patterns" and the much more static idea that you see in, for ex

I recommend "The Scrum guide" and "Extreme Programming Explained" as ways to learn about the systems themselves. Thinking about it, the book that actually taught me to understand what the early agile people thought was C

I'm sorry if I seem to be using the terms interchangeably. I do not intend to, but Scrum is the particular tactic I have seen used to accomplish what I understand agile to be. I agree that anyone who is dogmatic about "doing Scrum

It's interesting because "agile" can fail on both sides. This lampoons the enterprise side, in which you adopt "agile" practices inside rigorous change control and long requirements documents. But there is also the

I don't think this is inherent in the idea. You can absolutely make an interface somewhat like this that could arrive at general solutions. Indeed, I think Bret would consider this most of the point. He covers this in "Up and down

But, that is a bit different. Function calls return one value because expressions evaluate to one value. Functions accept multiple arguments the same way any expression can be made up of multiple values. What the formal parameters allow is

This is the outstanding example of how elevating special function return data into a type adds power, because you've just described a monad.

Why not have these on data? If they only get returned from one function call, you have to manually deal with them in each function. If attached to data, they can get aggregated over large chains of fn calls.

A proof by contradiction: Assume a language where functions do not only return one value. Now, consider each function in this language. It either returns the same number of values each time, where each has a specific meaning, and they are d

Yeah, took me a second to wrap my head around the Om todo code. I've updated my comment with links to show how it works.

"Immediate mode" is used as a metaphor here. He doesn't want to actually do graphics work. He wants to send things out to get drawn and have them get batched up appropriately and only rendered when needed.

Om looks very interesting and seems to handle exactly what I've been looking for. We have reactive widgets, which is great for making changes in the data automatically update the UI. But the hard part is closing the loop: how does the

The contest limitations rule out most of the likely attack vectors for breaking the protocol in the real world. It's like saying "Our bank vans are 100% secure. Just try stealing money from them without puncturing our tires or bri

Hmm, I don't see that at all. Every company has a culture, a way of making decisions, and a way things get done. We're talking about how those happen. That can include things like "most people do GTD", "most communi

I agree that some companies use "culture fit" as an excuse to eliminate diversity. But that doesn't mean that "culture fit" isn't a real thing when not abused in this way. I have found "culture fit" t

Yep, these are all conventions used in hand-written Latin texts of the time. I believe the 9-looking mark is short for "us" at the end of a word. See the top of the right column on that page: "Et vidit de9 qd esset" wher

A really interesting book on the characteristics of written and printed letterforms is "The stroke" [0]. One really interesting thing is the way that writing and reading have changed more than one might expect. A few anecdotes: -

There is (debated) speculation that Gutenberg made several forms of some letters with different widths so that he could justify lines with very small adjustments rather than adding space between words. The Wikipedia microtypography page has

When books were hand-written, anything that took longer to do was more expensive: extra colors, pictures, or scripts that required longer to write. This printed book is attempting to incorporate elements from a very fancy handwritten versio

There are two factors here: 1. illegible to whom? 2. what do you expect a book to look like? The Textura letter forms would have been more familiar to readers at the time, and were used widely in German until surprisingly recently. Even tod

Yes, "not ready" is exactly right. And this is one of Bret's points: Engelbart wasn't actually interested in technology itself. He was interested in sociology: creating groups of people who were ready to do transformativ

The point Bret is making is deeper: Skype and Screenhero shouldn't have to be 'applications' that dig into mucky parts of the OS to try to get screen and pointer sharing to work. And even with those applications, other applic

Well then awesome. Thanks for making things better! (And yes, I did try it. Didn't turn out great for me, but I have a variety of fun medical problems I wouldn't expect to see covered here.)

I'm speechless. I'm going to read the publications in the about page to see what went into this because, at first glance, it appears to be very poor information design: - The use of a circular arrangement is questionable. Judging

In this sense, "native focused" is not about what it does do, but what it doesn't do: - It probably doesn't work in IE or Firefox, because it's focused on working inside embedded WebKit/Blink. - It probably isn
