If you don't know the specifics, why the hell are you even arguing this point?

The difference between traditional and simplified Chinese characters is more than simply different fonts. Part of the difficulty is that some simplified characters map to multiple traditional characters, which means that converting from one

This is a blog whose latest entries deal with Xcode 6.0 beta 3 (out of at least 7 eventual betas, many of which made substantial changes to the language). Right now, the 'standard' Swift version is Xcode 6.1's (Swift 1.1), an

I enjoyed Metroid Prime 3. Probably the first and the last console shooter type game I'll ever enjoy. It was a pity more games didn't bother exploring using the Wiimote as a pointing device, although the Wii's underwhelming g

It's easy to tell people to quit their shitty jobs and pursue their passions. It's especially easy if one is an "American hedge fund manager, entrepreneur, bestselling author, and podcaster"; i.e. financially independent

Given that the ECMAScript community has (for good reason; "don't break the web") decided to avoid backwards-incompatible changes, that necessarily places a limit on the amount of "fixing" they can do to the language

I think the missing piece is here: "I am not questioning the many benefits of broadening or learning activities, just the premise that they lead to any sort of mastery." - Rich Hickey (from the same gist). Norvig is speaking about

Deadlines (self-imposed, even) make a huge difference for me. Being the lazy, unmotivated, dissolute individual that I am, I can confidently say that some of the most productive, sustained learning efforts I undertook these past few years w

I heartily recommend everyone with a Google account follow that link and double-check your security and allowed app settings. (Also take some time to go through your app-specific passwords and revoke any that aren't relevant anymore.)

Question (not being sarcastic): what's the difference between 'science-based medicine' and 'evidence-based medicine'? I did a quick Wikipedia search, but the former just redirects to the latter.

Another interesting thing to try (and maybe complementary as well) is building an interpreter or compiler for a language you like, trying to match the spec and feature set as closely as possible, and (hopefully) gaining more insight into th

Potential users can decide whether or not it's a poor choice themselves. I suspect the language would be more popular than a strict reading of its merits might suggest.

Swift has its own standard library, Foundation for things that fall outside the purview of the native stdlib (e.g. JSON parsing and regular expressions), and ApplicationKit/UIKit for GUI stuff. A multiplatform Swift + stdlib would alre

It looks like the annotations will allow the compiler to produce warnings when compiling the Objective-C code, so that's something: "However, nullability annotations—in addition to improving the experience in Swift—provide new war

Thanks! That makes a lot of sense.

Just out of curiosity, is it stated anywhere that Swift is memory-safe in parallel mode? Or is this a necessary prerequisite for reference-counted objects to be safely used with Grand Central Dispatch? (I assume that whatever implementation

I use a combination of SourceTree and the command line for my workflow, and can heartily recommend it. Some operations are just more intuitive to me when using the GUI such as: - staging portions of many files scattered across a directo

Of course. Understanding the underlying principles is necessary but not sufficient wrt the practice of engineering.

I like how, out of the 20 examples, 10 of them essentially copied the HTML snippet in the 'Coder' section of the 2012 image. Most of them even left the "jedi" div intact. On the other hand, only 6 of the examples copied

I wonder if creating a wrapper struct (let's call it Buffer) which combines an UnsafeMutablePointer and an UnsafeMutableBufferPointer would improve the language ergonomics while keeping the performance of the 'Swift*' version

That's quite plausible.

The code isn't quite as terrible if compiled with optimizations on. I like your hypothesis elsewhere in the thread, that the optimization pass is probably removing unneeded array copying that hinder the performance of the debug build.
