Comment: Re: Even Apple is abandoning Objective-C (Score 1) 372

Which brings me back to my original point. There are millions of lines of Obj-C out there, that will need to be maintained or improved for decades. Even if developers wanted to, Swift isn't compatible with a lot of use cases. And brand new Obj-C code is being written and shipped today by companies including Apple. Yes, Swift is a great new addition, but Obj-C will be around for few decades more.

By no measurable metric based in reality is Obj-C dead. Obj-C is as dead as Visual C++ became when Microsoff rolled out C#, in that it's not. Multiple languages is great. This isn't some Highlanderish situation that you're trying to make it out to be.

If OP learns Obj-C he's have a skill valuable for many many years to come. And I'm not saying that's what he should do. C++ is valuable too. But it's not a dead end, and if you say that, you really don't understand the realities of maintaining existing products, or the use cases of Swiff va, Obj-C at this point. I have projects still where Swift wouldn't be able to replace the Obj-C source entirely even if I wanted it to.

From http://www.raywenderlich.com/74138/swift-language-faq:

So you can still use Objective-C. However, Apple seems to be encouraging you to use Swift for any new development, while not expecting you to go back and re-write all of your Objective-C code.

From www.archer-soft.com/en/blog/technology-swift-vs-acobjective-c-pros-and-cons:

Swift was created in order to replace Objective-C, however, Swift is capable of working alongside Objective-C while using Cocoa and Cocoa Touch frameworks.

None of which are first party sources. Please cite one.

Here, I'll help you out. Here is a quote from one of your own sources:
"To quote Apple, “Objective-C is not going away, both Swift and Objective-C are first class citizens for doing Cocoa and Cocoa Touch development.”"

You're purposely digging around Apple's own statements that Swift and Objective-C are first class citizens.

Wait, first class citizens? That sounds a lot like what I said in an earlier reply. Hmmmmmm.

Of course Apple hasn't said Objective-C is a dead end. There would be a revolt and a mass fleeing from the platform if they did that.

...from their own developers? Again, out of the whole community, they have the largest Obj-C source base. If they abandon Obj-C within the next 10 years, they won't be able to ship anything. And it's going to take at least a decade to rewrite everything, if that was even their goal. During which time they ship no features. Apple can't abandon Obj-C because they need to use Obj-C. If they abandon Obj-C, they abandon Mac OS X and iOS. And they will be done in the market. And given that new API is still written in Obj-C, that's a process they haven't even started yet. In April they're shipping a brand new hardware platform that still runs on Obj-C.

For a past data point, Microsoft said with Vista they were going to rewrite Windows in C#. How did that go? Replacing an entire language is simply not realistic. If you're an engineer, you should know that.

Furthermore, once you're talking about the pain and suffering in moving everything to Swift, maintaining Obj-C looks like a far easier and more desirable costume. And that's what Apple is doing.

But they sure as hell aren't encouraging people to stay on Objective-C instead of moving to Swift.

I've talked with engineers on the Swift team who've said that's not the intention (and are wondering why the public thinks that). But please. Do go on.

I've read several articles and summaries (including on Slashdot) that have made it clear Apple wants people to use Swift.

"I've read articles from other people who think they know what they are talking about, and they wrote something that they think is right. Look at me! I'm such an expert!"

Oh, wait. Never mind. Apple person. You don't deal with the same reality as the rest of the world.

I... deal with the realities on the Apple platform?

Apple has made it clear their development future lies in Swift, not Objective-C.

That means you're choosing between a popular, well supported language and a dead end.

The choice should be obvious.

They've done no such thing. The biggest writer and maintainer of Obj-C code is Apple. They're sitting on a huge source base they'll continue developing on. Please link me to where Apple has said Swift is replacing Obj-C. Because they haven't. And they've said the opposite many times. Everything I've read/heard is that Obj-C will continue to be a first class language on iOS and Mac (with Swift and Obj-C both being considered first class languages.) You can have more than one language on a single platform. Shocking, I know.

Not to mention, for such a dead end, Apple's still writing a lot of new Obj-C. The iWatch OS (what runs on the watch itself) is Obj-C. Apple has not shipped a single API on Mac or iOS written in Swift. Not one. So it makes zero sense that Apple would consider Obj-C a dead language, and yet continue to write source they'll have to maintain for years in it. And if you think Apple is going to rewrite the millions of lines of Obj-C in Mac OS X and iOS in Swift, you really don't understand software engineering very well.

Another problem is that Swift is missing basic language features. Obj-C can link to C++ code. Swift? Nope. That alone means Swift can't replace Obj-C code. Everyone has C++ code they need to link to. Apple has C++ they need to link to in their own APIs. So does Adobe. Microsoft. And they'll probably fix it in the future. But you can't even approach suggesting Swift is going to replace Obj-C with a straight face until that is fixed.

Now look, I'm not trying to argue against Swift here. It's a valuable language to use and learn. This isn't a desperate "Obj-C forever!" post. But if you think Obj-C is going anywhere in the next decade or two... It can't. Apple will continue upgrading it, and continue supporting it, or else they're going to end up putting themselves in a corner where they can't even maintain their own software. That's not opinion, that's realism. It's knowing when a tool is right for a problem. And we're nowhere near Swift even being able to entirely replace Obj-C in usage.

Heck, the last Xcode beta even shipped with some upgrades to Obj-C. So I don't even need to argue that point. It's not a question of if Apple will keep advancing Obj-C. They are.

Isn't Microsoft announcing a new web browser intended to replace Internet Explorer today? Maybe it'll be open source. Maybe it'll even be based on Webkit.

I sure hope not. We need competing browser engines to keep things honest. The competition between them is the only way we ever get standards compliance.

Spoken by someone who wasn't around for the web browser wars of the 90s...

Multiple browsers led to less compliance, not more. Both Netscape and IE were in a rush to add their own non standard HTML elements to "outdate" the other. ActiveX didn't come along at a time that IE owned the market. ActiveX came along at a time when IE was in fierce competition with Netscape, and needed to BREAK the standard to push Netscape out of the market.

Having lived through that, I've never understood the logic of "we need multiple browsers to maintain standards." That's never actually happened in practice. It's like free market philosophy gone amok. Even today, we still see that a bit with either draft or pre-draft things getting added to web browsers outside of standards. Stuff like NaCL is not part of any web spec, and is entirely proprietary to Google, but hey, even with all the competition that's supposed to stop that, it still exists. Because competition promotes people creating their own proprietary stuff to beat the other browsers with.

I also disagree about C being "incredibly complex for a beginner". I found C to be very easy to grasp and very good at exposing what the computer is actually doing under the hood. I would agree that programming C well is complex (and also time-consuming), but that is because it is simple, not because it is complex.

As someone who went down this path and is now a professional software developer many years later... C sucks as an intro language.

Yes, it's very important for the work I do now. It's clean, simple, and easy to understand. It's also totally useless to a beginner.

I used BASIC (and HyperCard) way back when I was a kid because I could actually do things in it. Want to code a 3D game? I could do that. How about something that could play movies? Yep, easy. A basic text editor? I could do that too. With C? Lot's of hello world and "add these numbers together." C's minimalistic nature may be a strength for actual practice, but as a kid who wants to actually create things quickly, it sucks. I'd argue early education is about getting kids interested in coding, with less of an emphasis on actual practice they might use in a job 10 years down the road first. Just get them in the door first.

If C was my only intro to programming I would have lost my mind. Try to get more kids interested in development with only a command line interface and see how that goes. (Yes, there are libraries like SDL, but that takes you fair outside the realm of novice student development.)

Or a spreadsheet? (Sure, a small fraction of people will have monster multi-tab sheets, but they're idiots.)
Email programs?
Web browsers get a big win from multi-processing, but not parallel algorithms.

Linus is right: most of what we do has limited need for massive parallelization, and the work that does benefit from parallelization has been parallelized.

This is kind of silly. Rendering, indexing and searching get pretty easy boosts from parallelization. That applies to all three cases you've listed above. Web browsers especially love tiled parallel rendering (very rarely these days does your web browser output get rendered into one giant buffer), and that can apply to spreadsheets to.

A better question is how much parallelization we need for the average user. While the software algorithms should nicely scale to any reasonable processor/thread count, on the hardware side you do have to ask how many cores we really need, especially in since a lot of users are happy right now. But targeting these sorts of operations as a single thread is also the entirely wrong approach. It's not power efficient for mobile users, and it drastically limits the gains your code will see on new hardware, while competing source bases pass you up.

To be fair, teacher pay sucks. We all know it. There isn't a debate there.

So you don't exactly make a solid point by saying "Hey look! Women dominate in all the crappy low paying jobs! How are they oppressed?"

Do women dominate in teaching because they choose to go into teaching, or because society is corralling them into teaching because it's pretty much on the bottom end of the career ladder?

I'll tell you, any time I look at teaching (which I'd be interested in), I go "hell no" when I see the pay scales, and go back to my normal engineering job.

If you think discrimination is not a thing, perhaps you're deluded enough to think that women, as a large group, are all collectively putting themselves into low paying, low recognition work.

For bonus points, break out gender ratios in education teaching by pay scale. You'll find as the level of academia and pay increases, the ratio of women also declines. Gee, that's funny.

If you commit an illegal activity in Thailand, and then enter the United States, there is a chance that the US could return you to Thailand. If you do something that is illegal in Thailand but not illegal in the United States in the United Staes, then it does not matter at all. Only US law applies to acts committed in the US.

I don't know where you learned your understanding of extradition laws, but this is so far out in right field. Maybe you should lay off the internet conspiracy crack for a while.

There's a lot on mapping a bus address to a memory address for DMA, but nothing addressing the security implications of doing so, or what devices are allowed to do, just broad hints like the buffer has to exist in a DMA-able part of memory without saying if that's a security implication or a hardware implication.

It would be nice to see a follow up article on if/how USB 3.0 protects against these things, because I'm not a kernel USB developer sort of guy, so while I know DMA is there, I'm not feeling like I'd be able to dissect these implementation specs.

I'm pretty sure in the case of USB 3 that DMA is a function of the host controller. A device by itself cannot inject into arbitrary memory. This thunderbolt "vulnerability" is the equivalent of the windows autorun on insertion function that was disabled years ago. Only this functions above the level of the current user (aka much worse).

I'm looking up DMA for USB3. Although there are some ways to secure DMA (like a white list of addresses/sizes that are safe to write to), all of the advertised functionality of USB3, such as the sustained data rates, would be very hard to achieve if you didn't have direct access to memory. That's why Firewire ruled for live streaming of data for so long: DMA made it's rates reliable, whereas USB's dependence on the controller and CPU for memory transfers made the throughput more flakey.
