This is yet another example of a piece of "amazing" new technology which net magazines like Wired love to write about. They are always promising something which is a "quantum leap" ahead of current technology, but it's always 5 years down the line. And then, 5 years later do we see this? No, it's just more of the same.

Instant On isn't accurate. (Score:4)
Really, this just doesn't have much to do with instant on technology.
It's true. As useful as it is to require no power to store a charge, neither desktops nor servers have any serious problem with power--they're both plugged into a wall! There's no reason for mature DRAM memory to not receive the trickle charge it requires to keep its contents from drifting away. Problems come when operating systems (primarily) and motherboard standards fail to build in stasis modes--for all the determinism of computers, I find it rather surprising that the entire system cannot be simultaneously frozen until a given restart interrupt is triggered. But that's the situation we face--it's not that the memory doesn't last, it's that we don't know how to deal with a house of cards we don't need to rebuild every so often.
Where I see this technology being useful is in laptops, or anything else where "power just to suspend" is a real issue. Heck, even for normal operation, memory can be a real drain on power: Witness the effect of increasing from 2 to 8 MB of RAM on a Palm V(it's significant!). So this does matter for pervasive computing, as the article suggests.
But it has almost nothing to do with "instant on". I do forsee it being implemented in systems which don't want to have to "recover state from hard drive" or "implement a trickle charge system to keep existing state", but that's not so much a break through. The reduced power load scene DOES seem interesting, but lets not forget just how mature a technlogy DRAM is. They'll have to do some pretty amazing work with the MRAM to surpass DRAM. By then, where will DRAM be? Remember, Intel has its dominance partly out of the sheer amount of resources they can put into making the horrifically complex x86 fast. 21bil is alot of money to lose to MRAM!

I was wondering why we cannot do that right now. Can't the whole memory be put into the swap partition on shutdown, and some special version of LILO just restore it? I would think the time to swap in 100M from the disk would be pretty small. Biggest problem is that all the hardware has to be reinitialized, I guess new "poweroff/on" signals have to be sent to every process and a whole lot of programs and drivers need to be rewritten to reinit hardware on these signals. I can also see these being so badly written that in fact the "instant-on" is no longer instant, as each takes many seconds to reinit...
This will have almost miniscule effect on rebooting. The typical application spends most of it's time "initializing", not swapping in stuff from disk.

Exactly. England got a great start in IT because of it. We'd definitely have dropped down a league as a country if it weren't for it. Unfortunately, the lack of decent internet access is starting to pull us back.
BTW, remember the time that Clive Sinclair was reported as bashing the BCC guy over the head with a rolled up magazine containing an ad which slapped down Sinclair for it's lack of quality control?

What is it about the net that encourages these places to publish this sort of rubbish?
So what about Popular Science? The point behind tech magazines and tech news, at least personally, I like to see new ideas and innovations, whether or not they will be successful in a few years.
One of the things I think contribute to the notion that this stuff isn't successful is simply because by the time is does come around, so much more has been improve that it doesn't seem like a big leap... -- ever wonder why someone who hasn't seen you for 10 years is struck by 'how much you've grown', and yet the person you've known since then notices nothing? It's perception...
Right now, anything 5 years down the road seems almost too good to be true. When we get there, it's either been done to death or we've slowly got to the point where it's no big deal, and we forget how good it was when we first heard about it.
I say good work Slashdot, I/we love to see new technologies posted as news, simply because it encourages inspiration, creativity, ideas and enlightenment.

1. Memory that is zero'ed out is no different from random memory, if there are no pointers to it. If the machine is rebooting or powering up, the chipset would most likely just reset the CPU's pointers and go through the normal bootup sequence. It doesn't need to zero out the memory.
2. The reset switch just triggers the same chipset function as I mentioned in #1.

the bbc seriously rooled for _serious_ computer hobbyists
the Basic it used had procedures and functions not just gosubs - i never used a gosub in all the years I spent programming on it.
it was 32k on the Model B, the Model A had 16k!
it had a memory mapped i/o port and four a/d converters (i built a steering wheel out of a 10k pot to play Revs). I miss that stuff on my inferior but faster PC.
I've still got my two BBC's and occasionally play chuckie egg or frak!
I computerised my dad's business on it when I was 13 before the company he had the franchise from computerised theirs so our stock levels and money were always what they expected when they audited us (the difference in or out of our pockets - good days and ten years before they caught on to computers - much $-).

Well I'm glad you did because you answer was very dignified
the spectrum didn't even have a proper keyboard!
And you could sit it on your lap while sitting on the sofa and play games in comfort.
ah, well it always did look more like a remote control
Anyway, from what I've seen, most cheap PC keyboards use Spectrum keyboard technology just putting solid plastic moving bits over the top.
hehe those babys are well annoying if you take them apart. I always buy the ones with good old switches.
nah, all *serious* computer hobbyists needed was bus lines out the back and IIRC, both the BBC and the spectrum had those.
yeah but... oh i can't think of anything
Basic, who ever used basic? Assembler was where it was at.
Well I was just telling ppl. Basic is always regarded as a lower form of life but BBC Basic was at a higher level. To be honest I never really used a Speccy much I'm just predjudiced. But if you had to use Sinclair basic then I'm not surprised you found assembler easier
the beeb had no space for basic programs anyway
Yeah I learned the hard way. I started a board game idea for my O'Level computer studies but by the time I'd finished the board there was no room for the logic. I submitted something else I'd already written and got a U for the practical. Luckily I was an expert on Kimball tags etc. and still got an A over all!
it was 32k on the Model B, the Model A had 16k!
And the Spectrum had 41k of available memory
Oh, so you could write greedy programs then
I mean, why tie up valuable memory space for IO
hehe I suppose two bytes can make all the difference
a/d is OK (BTW, you can do that with your PC joystick port if you're careful)
Yub I know but I don't think you can get a DirectX driver for 10k pots
And of course, the spectrum had a steering wheel too
Was it made out of dead flesh rubber?
Ah, yes. The power of the BBC. You didn't have to go to the trouble of using more than the fingers of two hands to count the number of good games
Well like most ppl I'll say Elite, Elite, Elite
The Repton series, text adventures
In fact I've got about 30 games all of which I still play occasionally. It was a shortfall of the thing but that's what C64's were for
Try writing a database on a crappy Spectrum.
I'm sorry for saying crappy, it was the teenager in me. Serialising your data to floppy disk or tape was well handy. 18 years later and the only thing that has changed is the amount of data and the fact I use HTML as the presentation layer!
The Microdrive was a piece of crap.
They looked flashy though - I was tempted for a wee while
It was a quarter of the price of the BBC, the manual was excellent and you could buy any extra stuff you needed and of course, it didn't suck
I still think it sucked but you were obviously happy with it. I've got a ZX81 (with 16k) and that was a serious breakthrough. Hats of to Clive. It's a shame the Spectrum wasn't such a leap as the ZX81 (well there was the ZX80 but you know what I mean - I hope)
I'm glad we Brits had our own computer scene because I think it has given us something unique. If I'd had a C64 I think I wouldn't be such a coder as I am now. The BBC almost forced me to learn about computers in a way the games machines would never have done. Thank you Acorn and thank you Clive Sinclair.

the real use for this technology is yet to come. instant on will be irrelevant 5 years from now. IF the desktop computer prevails. it'll probably be used as some kind of very fast storage or transport media (a la zipdrives or something). caching comes to mind too. if the most accessed records of a huge database are stored here, instead of on my 100 XByte HDD, i could see a pretty decent performance boost. also, this is the kind of technology that I'd like to see in game consoles, webpads, cellphones and that sort of thing, where software tends to be much more static and stable (remember microsoft still hasn't taken over that field yet). my point is, the whole thing, as is presented, is similar to saying "10 years from now we'll have holographic storage systems 2 billion times as fast and large as today's storage media, that will revolutionize the way you store mp3's!.
