Immutability and Thread Safety

it depends on what the definition of "is" is

When I talk about immutable collections and immutable objects being thread-safe, what do I really mean by that?

Part of what makes traditional multithreaded programming so difficult is that you never have truly accurate information about the state of things. If you ask a list "are you empty?" and the list says . . .

Why I Love UIKit

simple but easy

Russ Bishop
April 06, 2014

I don't want my ranting and complaining to give the impression that I dislike UIKit; quite the opposite in fact.

Here's a simple piece of code I just wrote:

 self.brightnessLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
 self.brightnessLabel. . . .

UIDatePicker: how I hate you

no, seriously

Oh UIDatePicker how I hate thee.

While working on Storm Sim for iOS 7 I ran into a problem on the Sleep Timer screen. There, I am using a UIDatePicker in countdown timer mode. This is what it looked like (I had already given up on trying to get a dark background for that screen; the UIDatePicker won't let you change text color.)

Don't Run You Own Servers

Thanks, but no . . .

I was listening to Debug #32: John Siracusa on Copland 2010 in which the subject of Apple needing a next-generation language was discussed.

The elephant in the room seems to be why not take advantage of C#? Guy and John both seemed to dismiss it out of hand, but it hits all the requirements:

  1. It's an ECMA standard, . . .

Seriously Apple?

Try opening this file with Keynote 09

Russ Bishop

I understand you updated your apps; that's totally cool.

What isn't cool is giving me a message that my presentation is too old and to try opening it with Keynote 09. Which I no longer have.

Would it have killed you to take that conversion code, package it up, and embed it in the new Keynote? You know, like a sane . . .

tl;dr: it doesn't work

Russ Bishop
March 29, 2014

A quick heads up: apparently UIScreen.wantsSoftwareDimming doesn't work on iOS 7, the iPhone 5S, or both. I was unable to detect a difference in the brightness levels no matter what that setting was at; previously you had to set that flag then adjust the brightness to make it take effect. (I've always felt that LCD brightness levels . . .
