Reality check: Java 8 finally catches a multi-core break

JDX

Nobody said it didn't support threads. But you had to create and run the threads yourself, make sure they don't fight over the same data dangerously, etc... this is the traditional model of multi-threading very similar to using threading in MFC/Win32. More modern approaches mean parallel logic can be automatically split off to threads without you having to do it, in a similar idea to how Java doesn't make you have to manage memory, but does it for you.

Are Java lambdas similar to C#/C++ - nameless functions - or something else? How exactly does this allow automatic multi-threading where doing for(Object o : collection) doesn't? And, do C# lambdas also do automatic multithreading?

Re: Good performance? Scalable?

So says someone who either hasn't used Java since 2000, or hasn't updated their learning since then. Java's performance is not matter for subjective opinion, it can be measured directly.

Java is not as fast as C++ for bare algorithm implementation comparison. But it is NOT "miles slower" and the difference in speed between Java and Ruby is far greater than the difference between C++ and Java.

I speak not just as a programmer, but one with experience in the world of competitive coding contests where you are given a limited time for your code to process input data and return a result, where language performance is a big deal. Rather than quoting middle-management "I read Java was slow because it's interpreted" levels of misinformation.

Re: What's the big deal with charging every day?

Hand-winding a watch every day may be a slight inconvenience but it takes moments and you can keep the watch on, and do it anywhere. Having to take your watch off for an hour or 3 every day is a whole other issue. You'd get use to it but it is certainly inconvenient.

New WebCL toolkit hooks browser apps into GPUs – and that's not good news for Apple

"This a big deal because now you'll be able to access everything on the web"

Except there is no actual reason everything needs to be done through the web in the first place. This whole idea of moving every application to a web-site is just dumb. You shoe-horn your 3D game into a browser-plugin or rework your well-designed UI to use HTML and end up with something which is less good but "hey it's in the browser".

If you need the kind of processing power that only a GPU can give, write a proper application.

Virtual-reality Dev Kit 2 game goggles by Oculus – now with less vomit!

Maybe a silly question

But why don't these have a front-mounted camera (or one per eye) or even the option to open the front, so you can a)walk around with them on b)explore the whole augmented reality thing? It would seem to add another string to the thing's bow - opening up research and non-gaming applications as well.

Re: I can't see ...

Um, it's an entire fictional universe of which we've seen a single strand of history unfurl over 30 years and you can't imagine there are untold stories? It's a pretty shabby universe if the entire potential of the Force and the Sith is exhausted in 6 films.

Re: As much as I loved Star wars

Are they sequels, or parts of the same story? Most people would say IV, V & VI were 3 parts of a larger whole wouldn't they... and I thought VII - IX were written as part of that story way back when?

Re: Microsoft now down to 64%

Including all devices isn't the same thing at all though. PCs may be losing out in device market share but it's still relevant to analyse how the PC market breaks down, just as it is relevant to see how the mobile phone and tablet markets break down.

Re: This post has been deleted by a moderator

Good attempt but saying Linux has the best UI makes it a bit too obvious. Also since most of the software written and work done on computers by people generally is done on Windows computers, clearly Linux can't win productivity either.

"Linux NOT having a huge market share is a good thing for me."

Yeah whatever. When it sucks and nobody wants it you Linux dweebs will be all "we like it this way, keep the software crap and hard to use so noobs will stay away". If it ever does start to challenge for mainstream market share, you'll change your tune faster than an iPos Shuffle and be crowing about how you knew this day would come, Linux is so awesome, etc, etc.

Nobody is buying it.

Re: The Irrelevancy of Windows

Selling an OS isn't an anachronism. Software is free either because it's open source, or because the creator uses the software to make sales in a different way. OSX is only free because you're paying a "Mac Tax" (I hate the phrase "MS tax" but everyone else uses it) by buying their hardware - buy a new Mac or a new PC and you get the OS for free.

"applications from the Microsoft store did not slow down my computer"

Are you sure this isn't true, that they don't get suspended when not in use in the same way as mobile apps typically do?

I've no idea if they do or not, but it is a possibility.

Re: stating the bleedin obvious

Apple can "win the laptop game" without having majority market share. Just as with phones/tablets, by focusing on the top-end you maximise profits per unit. They aren't interested in selling products to people with no money (a H2G2 paraphrase).

Re: IMHO, It would be fair

"IMHO, It would be fair to compare the shares of each OS actually installed by users themselves"

No, that would be deliberately biasing results in favour of the result you want to see. It would also be asinine since uninstalling OSX on a Mac is an incredibly niche thing to do, and people don't uninstall Windows to install a new Windows (you said you wanted to measure people removing pre-installed OS). Probably 99.9% of manual Windows installs are done on machines which came with Windows in the first place.

If we purely focused on % of installs regardless of previous OS, then you'd still see OSX users upgrading to newer versions of OSX but the vast majority would STILL be Windows installs.

And that's even leaving aside the elephant in the room which is that most people are happy with the default OS. Saying anyone who doesn't re-install their OS isn't a relevant data-point is just stupid.

Re: It shouldn't need to persuade devs

Re: 8GB is pretty useless

I've an 8Gb phone and it's just fine. If your software makes swapping what music is stored on it trivially easy, it's not a big deal for many people.

If you don't use your smartphone phone for storing music/video but for apps, email, web-browsing and streaming audio/video, it's also not a big deal.

Re: @Tannin @JDX

"And your blind defence of Microsoft's biggest ever GUI design blunder is only matched by your fanboy zealotry."

I haven't ever said W8 Metro is good on the desktop. And my comment was not defending MS in any way.

Perhaps you should realise that pointing out flaws in someone else's stupid argument doesn't mean you endorse whatever they are complaining about.

But then making up lies (or being so blinkered you believe those lies) to try and score points is what being a rampant loser fanboi is all about.

Irony? When you sign up to FB you are voluntarily giving FB your data to use. You may not know what they want to do with that data, but it's no surprise they have the data and no great surprise - even if a disappointment - when they do use it.

FB wants your data and that's the point of their business model. Hardly the same as a government forcing them to provide your data, and trying to force them not to tell anyone this is happening.

And FB is serious about security - they don't want anyone else accessing your data because THEY want it to themselves :)
