Yeah, except for the facts that the leaky bolts that were the primary source of consternation last year (?) weren't part of the Chinese-built part of the bridge.

For someone who laments the failure of modern programmers to learn from the work of the past, the author seems to completely ignore the contributions of ML, ML-style type systems, and related languages to the profession of software engineer

I think an interesting life is important. I also think, though, that many people lead far more interesting lives than they realize. Some people are better than others at noticing and extracting the interesting parts of what would otherwise

He doesn't have actual questions. He's making an ad hominem attack against the author of a language that he's forced to use, but hates.

Swift supports ADTs and implements its Optional type as an ADT.

What a great summary of the utter baseness of this type of advertising: a stomach-turning body horror image I never wanted to see, some article calling strangers "morons" based on some stupid superficiality, and gossip about the p

Swift has "if case let" for that use case. (Admittedly, the syntax is a bit esoteric.)

"Advanced manufacturing requires management and communication skills and the ability to operate complex information-based factories" is meaningless consultant jargon. It would have been better to explain exactly what about advance

I'm not particularly enthused with how the code was presented. Here's a marginally more readable version of the first large snippet that still doesn't exceed 77 (or 79) characters in width: https://gist.github.com&

I've seen interest on the lists for modifying the model to allow a single failure type to be specified. I hope someone will write up a proposal once August rolls around and the lists are open again to new feature ideas.

Scala tries a lot harder than Swift to unify object-oriented and functional programming principles. For example, in Scala operators are (IIRC) implemented as methods on objects, there's a 'Nothing' bottom type that is used fo

That's bizarre. One thing I've noticed is that performing the string scanning operation is relatively cheap. (If the splitAndTrim code is modified to not use Strings and to return a [String.UTF16View], the runtime is around 1.2 se

Weird. I'm using the same version of Xcode, running on a trashcan Mac Pro running OS X 10.11.4.

After a bit more investigation, I found that if you replace the following code: result.append(begin == eos ? "" : String(cs[begin..<end.successor()])) with this: if begin == eos { result.append("") }

"This is a proposal and not a plan of record." Not only that, the git feature branch, if it ever existed, doesn't anymore.

To be clear, that document contains brainstorming by some core Swift team developers. It's neither implemented in Swift nor officially accepted as a guideline for future development.

Regarding strings... I briefly ran the code sample you graciously provided me with a month ago through the profiler ( https://gist.github.com/austinzheng/d6c674780a58cb63832c4df3... ). Long story short, it looks like the

I'm not saying the experiments were trustworthy or conducted properly. Only that the author of the article misunderstood the experimental setup. (To be precise, the comment about the null thruster was made by the author in a comment on

I am skeptical about the EmDrive (although I would very much like it to be real), and my opinion on the drive or its theoretical underpinnings is not really relevant, given my lack of knowledge about the field. But I don't think that w

My (highly speculative) guess is that your String issues were due to either/both: - Swift performance issues involving working with strings, some of which have been ameliorated by later releases; - 'Hidden' bridging between N

It's possible to write non-GUI command-line Swift programs that run on Linux (and certain other platforms). In terms of 'close to the metal', Swift is probably much closer to Rust or C++ than C# or Java, and is at least at th

I love C# and think it's a great language, but when it was as old as Swift is now it was widely perceived as a Java clone. In fact, even today C# and Java are much closer in language design philosophy and implementation than C# and Swi

No, just a 'greatest hits' compilation of the same things China detractors have been complaining about since 1995. Their analysis is no better than the already dubious "official" numbers.

Yes, because moving from vtables to message passing eliminates a whole class of semantic errors whose genesis is independent of the implementation details of the language. Thanks for making this clear.

Since I expect nothing less than clear, well-informed commentary from Hacker News regulars, I would be very interested in learning exactly what technical aspects make Rust, Python, and Go superior to Swift in each use case, as well as lesso
