How is this different to what OSs already do with file I/O? I don't what other OSs do, but Linux uses all available RAM that hasn't been specifically allocated for anything else as cache and buffer space. What am I missing?
Re: Oh please, not the tired old "640K" crap
Did 100Mbit ethernet or 54Mbit wi-fi turn out to be adequate? No.
Are consumers moving away from shifting data about in the LAN to shifting it in and out of the cloud? Yes
No, consumers aren't likely to utilize a 1Gbit connection 100% of the time, but when they upload or download something, the preference is likely to be; the quicker the better.
The basis for your argument seems to be about what people need. But the Internet isn't about what people need - Unlikely as it might sound, life can exist without the Internet! It is about what people want.
Re: Gigabit over copper?
"no idea why anyone needs gigabit internet connectivity at home..."
Which is a bit like the quote "640K ought to be enough for anybody."
Re: 32-bit vs 64-bit
Sure, you can have wider registers for SIMD operations (e.g. NEON), but you've got to load and store them somehow. A 64-bit data path throughout your architecture means you can move more data per operation which will benefit SIMD performance, so it is relevant. Incidentally, one of the major features of the ARMv8 architecture is enhanced SIMD support, making it standard and increasing the number of available 128-bit registers.
As mobile apps are generally audio/graphics DSP intensive, an increase in throughput is likely to be more useful to developers than the ability to address a vast and sparsely populated address space.
32-bit vs 64-bit
On a mobile device, I would have thought the 64-bit advantage is more about SIMD than address space.
Re: "too expressive in some ways, with features like closures..."@pjc158
Whether a language is a scripting language or not is related to the level of operations programs written in the language are intended to perform - It has nothing to with the paradigm(s) a language supports. A scripting language can be procedural, object-oriented and/or functional just as much as a systems language can be.
"too expressive in some ways, with features like closures..."
Closures are its main bloody asset! It's a functional language and the moment you treat it as such instead of trying to bend it into it isn't (like Java), it actually becomes quite pleasant to work with.
All tech specs and religious tendencies aside...
Who came up with the name 'Xbox One' anyway? They knew it would be going up against something called the PlayStation 4. Makes it sound like a 1st generation device. Anyone up for a game of pong?
"There would need to be a software layer, like Memcached, to present storage memory as pseudo-RAM to applications."
Is this not the job of the operating system? Why shouldn't this type of storage look just be treated like a block device? Applications needing raw speed can just mmap.
Sounds a bit like what ARM set out to achieve with their Thumb/Thumb2 instruction sets, but taking things one step further with proper data compression rather than just shrinking the instruction format.
The article doesn't mention what architecture this is targeting, although as it's Intel I'm guessing x86 because I can't imagine them getting back into smaller embedded stuff having dumped MCS-51, i960 and XScale a long time ago. If that's the case, it makes sense for the compression/decompression to be on chip so that code compatibility can be maintained. If compression had to be done at compile time, compatibility would go out of the window.
As for 'intelligent drapes, coffee machines, toothbrushes, baby monitors, stereos, alarm clocks, supermarket shelves, air-quality sensors, and more', surely that has been ARM's bread and butter since almost forever? It's hardly new for microcontrollers to be embedded in that kind of stuff and you don't need vast amounts of processing power or memory to achieve Internet connectivity.

Re: API, not language
Have you ever tried writing any significant amount of code in C using GTK+'s bloated piece of crap GObject system? I shudder to think how many hours of my life I've wasted manually specifying vtables and handling GObject properties. Glad I jumped that ship 20 months ago.
Yes, C is a vastly easier language to understand compared to C++ and can even be a more productive language in some circumstances... But not when you use it to manually implement everything C++ gives you out of the box minus the syntactic sugar.

Re: red herring
Well of course it was overpriced - That's how retail works! You think I don't know that a camera I pay £400 for costs bugger all for Samsung to manufacture?
There is barely anything inside a tablet computer. In the quantity Samsung makes stuff, the mark up they put on wholesale would cover the production cost of a 7" tablet several times over.
Televisions, phones, tablets and cameras are all essentially the same thing in different form factors these days and are becoming better at inter-operating. Samsung giving away tablets with purchases of other Samsung gear both makes it more likely that a consumer would chose a Samsung product over some other make - Especially at Christmas.. and it also means that a consumer with two inter-operating Samsung products (e.g. a tablet and camera) is likely to buy another Samsung product (e.g. a television) later on or maybe even at the same time.
Re: red herring
I didn't have to trade in anything. Bought a new camera from Amazon, got a Tab 2.0 with it for free + £50 cash back. Looks okay on paper to me.
Giving away Tab 2s with everything probably helped. I took the bait.

Re: Get it right next time
How do you make teaching attractive to the talented? Those who are talented in a particular field want to get on with exploring it and pushing boundaries, because they can. Would money really be enough to compensate people of that mindset for the dying inside that they would experience, regurgitating the same old shit, year in year out?
Re: Each language for its own purpose
There always seems to have been this misconception amongst embedded systems programmers (of which I am one, although seemingly more enlightened) that C++ is somehow inherently more resource hungry than C. This simply is not true. There are actually very few language features that impose memory or execution overhead (basically just exceptions and RTTI) and only do so if used.
Re: @Phil O'Sophical Sounds good
I can't tell if you're being serious or not.
Re: C++ put me off programming
The only time raw pointers have any place in C++ is when you're wrapping up legacy C code. In some ways, I wish C++ had never attempted to be backwards compatible with C - So many programmers treat C++ as C with classes (aka structs with functions), which doesn't even come close to utilising the language properly.
It also probably doesn't help that there are very few well written C++ libraries/frameworks out there to at least serve as an example of how C++ should be done properly. The STL is fantastic these days, especially with all that C++11 has added. Boost libraries aren't bad, but even having been a C++ programmer for 12 years, I sometimes find the complexity rather irritating. The problem is that, for the most part, the STL and Boost are libraries of generic classes and functions. Generics are absolutely right for containers, algorithms and such, but do nothing to serve as examples of how framework level or end application code should be structured. That isn't a criticism of the STL or Boost by the way - Certanily, as far as the STL is concerned, it is entirely appropriate that it be a library of generics and not much more because C++ is a systems language and its standard library must minimize its dependencies on any particular underlying platform.
At least with languages like Java, Ruby, Python etc. there are plenty of libraries (for better or worse) which beginners can both use and draw inspiration from when designing their own code. C++ is always going to be bewildering to the beginner without good real world examples to illustrate the language. Unfortunately, some of the more prevalent C++ frameworks, such as QT and wxWidgets treat C++ like it's still 1998 (arguably for legitimate reasons) and are, I think, examples of how things should NOT be done in modern C++.
'a UART to drive USB ports'
Yes. I was just observing that the USB interface was the one in use and the MIDI ports were being left redundant. Geez you're a hard crowd sometimes.
Nice picture on the BBC article of a device using USB instead of MIDI.

Re: Hello Intel
Intel has already been there and got the t-shirt. They inherited StrongARM from DEC, then went on to develop their XScale implementation of the ARMv5 architecture before flogging it to Marvell so that they could focus fully on x86. Can't see them doing a u-turn any time soon (even though they still hold some sort of ARM license apparently).
What about 64-bit pop stars?

Re: AMD or ATI
AMD CEO Rory Read: "We're the first company to offer both 64-bit ARM and x86 server processors"
So the article's assumption is perfectly valid I'd say.
AMD should have started pushing ARM chips a long time ago. I wonder what their approach to 'ultra-low power' will be.

Re: Not always about trust
I agree, that is what I wished she had done. But having not experienced being 70 yet, I can't say for sure that I, in her position, would have the clarity of mind for that solution to occur to me.
Not always about trust
What about those of us who live next to elderly people? I have no problem trusting my elderly neighbours but I don't want them being harassed every time I miss a delivery. I once missed a delivery of a 25kg micro lathe which ended up going to my neighbours (both in their 70s). The courier didn't bother leaving a card saying what they had done with the package, so two days later, my wife opens the front door to find the lady from next door struggling with the damn thing. I can't tell you how immensely guilty I felt about that.
Now I have to put a sticker on my door implying that I hate my neighbours when I don't? I can't even put up a sign of my own explaining that they are elderly because I don't want to be responsible for them being targeted by some charlatan salesman (like that prick selling alarms shown on Watchdog this week) because I have advertised that they are potentially vulnerable.
I'm in the wrong business.

"It’s not entirely clear to me why the Beagleboard is so expensive. Somebody in that Beagleboard value chain has got to be making a pile of money – I mean, $175 for a Pandaboard or $100 for a Beagleboard? Somebody’s got to be amassing a pile of cash there, because that’s a $10 chip in that device. I don’t know why they’re so expensive."
