Jevon's Paradox! https://en.m.wikipedia.org/wiki/Jevons's_paradox

> The other thing I would say is to stay close to professions that create and make things, and stay away from derivative professions like finance. I think makers increasingly have the power in our society.

Wow, interesting words from someone who works in finance.

Garbage collection is controlled by the mob.

Because it's part of a series: http://www.nytimes.com/2014/12/12/upshot/our-series-on-the-d...

Don't assume the worst!

Actually ComponentKit is built on GCD!

https://github.com/facebook/componentkit/blob/master/Compone...

GCD is fantastic—one of my absolute favorites. We're trying to solve a problem one level above that: exposing an API that doesn't require every view developer to know the details of managing GCD queues and updating a UICollectionView.

As for Autolayout, it's very powerful but isn't performant enough for layouts as complex as Facebook's News Feed. We tried it first before developing ComponentKit.

Will do shortly.

You're right about this. My terminology was incorrect.

Requires writing to executable pages, which iOS doesn't have.

pngquant is great. I make an iPhone app that displays transit maps. Transit maps are ideal candidates for quantization (limited color range, large blocks of color that are perfect for RLE) and I saved a lot of file size by quantizing the map tiles. Thanks pngquant!

Fatal flaw in this plan: unions. New York has already tried to switch to driverless subways, but progress is slow due to constant union interference.

Windows 1.01 feels much closer to Mac Classic than Windows 3.1 does. (Button appearance, close button on left, menus must be held down to stay open, "Get Info" instead of "Properties".)

To me (an American), that sentence seems incredibly lenient.

"Out of 86 guests, I've only had problems with 15 guests."

"only"? n.b.: If your business model is renting out luxury condos to people on the Internet, you're going to have a bad time. People will use them for parties.

BART jobs are quite supply constrained. Sure, union jobs are great if you can get one, but there aren't many to go around.

Plus, who would really enjoy working in a workplace where everyone doesn't care? I couldn't stand it even if I were paid more, couldn't lose my job, and had more vacation time.

That's precisely what he argued though: "A 2010 study by the Goldwater Institute identified "administrative bloat" as a leading reason for higher costs. The study found that many American universities now have more salaried administrators than teaching faculty."

What's more he doesn't propose eliminating federal aid or loan guarantees, he advocates letting you discharge student loan debt in bankruptcy and putting colleges on the hook for some percentage of that default.

Sounds like a great idea to me. Schools that equip their students for well-paying jobs have nothing to fear, but diploma mills out for easy loan money will suffer.

If the NSA was MITMing SSL communications on a wide scale, presumably the companies would notice that the cert fingerprints were not what the companies expected.

Teach her to pinch zoom. Double tap-zoom is a power user gesture.

Agreed—mostly because it's SIMPLE!

I took Brian Kernighan's class when I studied at Princeton. As part of the class I developed www.itrans.info which set me on my way to being an independent app developer. I'm enormously grateful for his class, his involvement with students at Princeton, and just how genuine he really is as a person on campus.

Correct.

Nice idea, but the sample code they show in the screenshot uses "FALSE" instead of NO (the Obj-C standard boolean literal).

I'm not sure how they did that (#define?) but stay far, far away. Imagine if you opened up a Ruby codebase and found out I had aliased NO to be the same as the language builtin false... yeesh.

Also, setting boolean instance variables to NO in init is silly since Obj-C objects are calloc'd, so all ivars are guaranteed to start with default values (nil/0/NO).

For webapps, I agree. There is no progression of state in a webapp's "controller" object: it's one shot and done.

For native apps in frameworks like Cocoa Touch of course it's an entirely different ballgame. A view controller has quite a bit of state, usually some different modes, maybe some enforced state transitions. So the controller pattern makes a lot of sense there.

The author is spot on about how some architectural oddities like one-method-classes come from Java's lack of functions as first class objects.

A ratio of 3:1 doesn't strike me as "almost as much energy as it produces." Would you say that if I gave you $3 for every $1 you gave me?

I mailed a package to Russia about 5 years ago. Recipient had to pay a bribe to get it.

This is because the iPhone 4 is missing a newer version of the crucial noise reduction chip:

The fact that Apple supported iOS 6 on the 3GS is proof that they're pretty serious about backwards compatibility.

"Nobody goes there anymore. It's too crowded." – Yogi Berra

That graph is incredibly misleading. It goes from $5000 segments to a $50000 segment—which the author has the nerve to label a discontinuity!

That's not to say income inequality isn't a problem, but misleading charts are the wrong way to make an argument.

This seems like an intentional misunderstanding for press attention. How do you get from "shipments of lithium-ion and lithium batteries on cargo aircraft" to banning laptops?

Thanks!

Use monkey patching in tests, never in production.

Monkey patching is fragile, but in tests, who cares? If it breaks, you see why and you fix it. Tests don't have to be held to the same level of reliability as production code.
