But how could already committed transactions suddenly disappear?
Easy. Your database goes tits up. You have a backup, you have a transaction file.
You stop the system, fix the problem, you revert to backup, and then tonight you will roll the transaction log forward and reinstate all the transactions you just erased. Probably duplicating the error that was originally made that cased the thing to crash...
Re: Apple/Samsung buying ARM
"They are all invested in the continuing independence of ARM."
And therein lies the key. the chip foundries want a stock bit of architecture that is open and compatible enough so that stock OS like android will run on it, so the real development is happening at the bottom - chip fab - and as the top - product and application design.
What they dont want is to be held to ransom by another chip fabber like Intel.
Ok these days porting an OS to a new chip isn't a huge deal, but why bother at all?
You have to look at where the entities involved are doing the added value. CPU design is not one of them. CPU integration is though.
Re: What would happen if Apple buys ARM?
"Steve Furber designed the original ARM for minimal silicon real estate and power consumption"
Er no. He designed it to be as cheap as possible to fabricate, because the original products it was designed for could not actually afford the foundry costs of a big chip.
An there it languished until mobile computing started to take off. suddenly the minimalist design was outperforming rivals in terms of battery life - and the rest is history.
Low power consumption was never a design objective: it was just a side effect of another one. Not wishing to take anything away from ARM, but it was - as many success stories are - a matter of being in the right place at the right time, often for all the wrong reasons.
My real admiration for ARM is the development of the business model, that allowed them to grow against the likes of INTEL without spending that sort of money. The understanding that ASIC technology could be used to leverage IP into a licensing model that required only what ARM could deliver - technical smarts - was the key.
"HP's decision to buy Autonomy effectively took $10Bn, piled it up and burned it."
ER no, it put it in Mike Lunch's pocketsesss and any other autonomy shareholders pockets.
Or parties Autonomy may have 'hired' as 'consultants'
Consider the following hypothetical problem.
You are running a large publicly owned company along with some fellow directors.
The shareholders get irritated if you pay yourselves more than a couple of million. The plebs. However they get very excited if you spend their money on something else.
So you go scouting for a 'story' This 'story' should be something that will superficially boost the share price of your employers. Because as directors you all have shares and share options. It only has to do it long enough to allow you to sell. The the share price can collapse and you buy back in.
You need a willing partner. So you find a firm which is more or less owned by one or two guys. Its books merely need look reasonable. They can be cooked in the short term goodwill written up as having real value as can IP. Whatever.
You make the acquisition. The lawyers underwriters financial advisers and accountants all make good money. The little firm makes good money. Your stock soars, you sell shares and the share price slowly drifts back.
That's what happened to me, anyway. Although it took a bit of time to realise what was going on. Then I sold my shares too and shut up.
The following I didn't think of at the time.
But what's this? You have been outsmarted by the little firm? how DARE they do what you were doing, make their own story and sell it to you? And you haven't a leg to stand on. You did the due diligence, but you asked the guys not to look to hard didn't you? In case you didn't get your 'story for the markets'. Now you have been out-sharked by a piranha! Instead of gradually writing down the useless asset over ten years, you've written 90% of it off in year one! and your stock is in free fall. You can't sell now! Worse, people are beginning to question your competence!
You are truly shafted. IF you start blaming the auditors, they probably have documentary evidence telling them to 'not look to hard' on your instructions.
If you blame the company you bought, it makes your due diligence look incompetent, and therefore you.
What you want is a three year long lawsuit that ends up with no one actually being any the wiser, in which time you may be able to burnish your tarnished reputation...

Re: Datacentre Question
you forgot the egregious Bjork, that androgynous alien with a screeching voice that thinks it's Art.
I suspect that if the maintainer exists under British jurisdiction he could be pursued.
It may cut both ways.
For example. when commenters claim that XYZ company is polluting the planet, and causing thousands of deaths, they may get called upon to actually prove it for a change.
Leaving aside hobbyists...
...the real value of 3D is fast prototyping and very short production runs, same as laser cutting.
For example. everything comes on an injection moulded plastic case. To manufacture such a case costs peanuts, once and only once, you have spent literally tens of thousands of dollars and or man hours making the tool. And them modifying it because marketing didn't 'like the feel of it'.
3D printing ( at least prototypes) allows you to arrive at the final shape cheaply and quickly, and even make enough units to fund the cost of getting an injection mould made.
As the materials that may be deposited increases in scope, so too will the applications. Its also less polluting to use additive technology rather than subtractive. A 3D printer is after all only a CNC 4 axis mill in reverse...that doesn't leave swarf and cutting fluid everywhere.Finally, it seems with certain limitations, to be able to create structures inside structures. The possibility of really good ball and socket joints exists, in a way you cant do subtracively, easily.
A solutin without a problem? No. But it takes time, when you have been used to designing things one way, to develop a new mind set such that the new way isn't just a replacement for the old, but a complete rethink in the way things are done altogether.
If you look at - say - the evolution of the domestic radio set, you see cases made first of wood, with steel chassis bolted inside, fretwork grilles and so on. Then bakelite replaced the wood. And then the printed circuit board replaced the chassis, and then ultimately we have the injection moulded case and PCB that together are exact fits to each other. Parts count drops dramatically as one moulding replaces lots of assembled 'bits'..Imagine 3D printing say, most of the wiring for set, the mechanical controls and the case as one unit, so you have plastic in plastic bearings for rotary or slide controls with knobs pre-moulded onto the shafts, and even the potentiometers pre moulded with a conductive plastic set of paths, already connected to wiring to take the signals to where they need to go. And stuck in the middle a PCB with a dozen connectors to the case wiring system. At last the wire-less wireless!
In economic terms you are replacing the cost of individual tooling for hundreds of different sets with a huge capital layout on a machine that can produce any design you want. 3D print the owners face, name and address in it. Hard to steal and re-sell an item, so personalised.
Its just another dimension to manufacturing, and as we in the 60's adapted to thinking more in terms of 'how can we get that onto the PCB, or mould it into the case' to save production costs, so too will tomorrows designers not be restrained by 'great idea, but there's no way to make it'.
Re: ECL and other stuff.
The only thing that gets my humble dual core celeron in a sweat is actually moving images. I can swerve the CPU usage right up by grabbing a window and stirring it round the screen..and as for full screen videos..well..especially flash ones. YUK.
But that is of course something a co processor can handle so much better.
Re: The next giant leap
whilst that works for some things, it doesn't work for others.,. E,g the massively compute intensive stuff done in matrix algebra is already coded as tight as it can go.
And huge fractions of bloatware are never executed at all. Or very seldom.
And sometimes shrinking code INCREASES execution speed. e.g JMP STANDARD_THING or CALL STANDARD_THING involves an extra jump or a call,. Inline coding does not and doesn't risk emptying a prefetched pipeline.
What is needed is thorough code review and analysis to spot where time is really being wasted.
computers scientists are dweebs. Software engineers are not.
Some of us started with electronics too.
Actually one way out of this mess is an ANALOGUE cell that can handle more than one bit - imagine 8 logic levels between one and 8 (0--5V) handled by a single switching element. 8 bit adder would be a snap..as would an 8 bit comparator
Re: The Tooth Fairy and Molten Salt Thorium Reactors
Oh dear. Spot price for Uranium oxide (which is by weight mostly uranium) is less than $40 /lb.
where do you get your information? Or do you simply make it up knowing its a total complete lie?
Re: The Tooth Fairy and Molten Salt Thorium Reactors
Who cares if its only a 5% burn up? The fuel isn't lost - it can be reprocessed and re-enriched and passed through again, and uranium is dirt cheap at less than £70/kg.

Re: Well, two thoughts...
Saying solar and wind can compete with nuclear is a bit like saying a clipper ship can compete with a nuclear submarine.
ESPECIALLY if you rule out hydro..
Let's run the idiot scenario of a solar wind and nuclear grid. Now these are technologies that actually do exist, so we don't need to invent pixie dust and powdered unicorn horn fuelled devices. We just go with what we know.
First of all, there will be times. Dark cold still winter evenings, typically in January or February when we will need around 60GW of power on today's grid, and the wind won't be blowing anywhere and the sun will have set.
So to cover these, we need 60GW of nuclear power.
That 60GW of nuclear power can run the entire nation. Its costly to build but its dirt cheap to run and emits no carbon. Neither does it need any fossil fuel. And without fossil fuel we have to have it anyway.
Why on earth would we add renewables to it?
To add energy security? we don't need to. Nukes already have a decade or two of fuel stored and to bulk buy more to make that 100 years would be peanuts.
To reduce emissions? Pardon me, emissions are, once the nukes are built, already zero. And you have to build the nukes. Building the renewables would increase emissions in the build process. And probably the maintenance phase as well.
To reduce fuel burn? why would we even BOTHER since nuclear fuel has a massive EROI anyway, and is dirt cheap.
No, gentlemen, once we have an adequacy of nuclear power, intermittent renewables simply cannot compete. They are more expensive they cannot be dispatched and they cannot be stored and they add nothing anybody wants or needs to an all-out nuclear grid.
They are all cost and absolutely NO BENEFIT WHATSOEVER.
Once you say 'lets have some nuclear power' at ALL, the (rational*) case for having any renewables actually vanishes.
This is why the anti-nuclear lobby is so vociferous. The intermittent renewables have no chance whatsoever of competing with nuclear, which is why if you have companies like Vattenfall and Siemens in your country running your grid, you have to BAN nuclear altogether, or people will start asking questions.
As indeed they are, already...
The ONLY situation where intermittent renewables 'work' is there they can be offset with a lot of pre-existant paid for hydro that can't be run flat because its rainfall limited. THAT can then be turned down on windy or sunny days to conserve water.
But even there, the costs exceed using nuclear to do the same job. Switzerland is about IIRC 60/40 nuclear hydro and it works marvellously. The 60% nuclear covers the base load and the 40% hydro is used to cover the peaks.
IN short there is not a single job that intermittent renewables can do that can't be done better and cheaper by nuclear power.
Beware of people who say we will need, or the future is, 'nuclear and renewables': they are not logical people who understand power generation. They are politically motivated or profit motivated to keep 'renewables' alive long past the time when the stench of green corruptions has begun to become obvious to everyone.
*The 'case for renewables' is in fact not rational at all in any case, they represent a cosmetic solution that doesn't actually work (overall integrating them into a real world fossil grid makes no impact on its emissions commensurate with the amount they generate) to a problem that probably does not exist either. CO2 impact is widely seen as either insignificant, beneficial, or a mild combination of both. Its real purpose is top make money and capture the illiterate green vote.
If renewables are the future I am glad I wont be living in it.
And glad I wasn't living in the past where renewables were the present.
Anybody who says renewables are the future
- hankers after the Dark ages
- wants to kill most of the human race (not an unreasonable position given how crowded with green idiots its getting)
- is lying
- has an interest in a renewables company
Or is simply a batshit stark raving bonkers swivel eyed loon.
Re: Maybe it is time for MS to exit stage Left...

Unless you count the version on the second hand laptop I bought that was immediately erased and replaced with Linux.
Pro users who don't have 'special needs' that some MS app is essential for, don't need windows, and consumers don't want it. They would rather have a slab.

Re: LOL! Scam.
I think that there is a real genuine and growing market for more secure email than currently exists: Today's emails are little more secure than an analogue mobile phone was.
Obviously we wouldn't use SMTP in its current form.
You may joke, but its one application I WOULD think is worth coding up. Blackberry showed that there is a market for secure comms between parties. Even if they couldn't make a phone worth a damn.
Re: Secure email
But then what do you do when the recipient has to be anonymous? How do you send an email with a blank envelope?
Traditionally you put an advert in the personal columns of the Times.
Imagine a system where you scan 100,000 headers on some website all encrypted to find the one that matches your private key and represents a message to you. It also contains the URL of your encrypted message or a further key that can be used to retrieve it.
Re: Trust and Security
If you wanted to design a communication and dissemination system that offered privacy to the individuals using the system; you wouldn't design the internet, as it is (and is used) today. Indeed, if privacy was your overriding design aim, probably any connected-system at all.
The whole point of a cipher is to ensure that secure communications are transmitted over an insecure link.
From the man, that you couldn't trust, on a horse carrying a letter, to radio and the Internet, the problem is well known and well defined.
All it would take would be the widespread adoption of mail clients that could detect an encrypted message and decide it locally using your private key.
Re: PC installed base
The classical model of a market is a vbleeding edge early adopter phase, followed by a rising star stage, followed by a cash cow stage - where innovation is slender, and volumes slow down, to teh final satge of maturity, followed by death as something better takes over the market space.
Desktop PCS are at the end of the cash cow phase, and are entering a mature phase, and being partially killed off by the emergence of 'mobile technology' and 'the internet of things'
To put it bluntly, the desktop PC is becoming a minority way to access computing resources and is in reality moving upmarket into the commercial and industrial arena, and away from the consumer.
Computing has forked..into professional and consumer. Microsoft is well poised to fall between the two stools.
No one won the OS war. It simply has become irrelevant. TCP/IP and HTML won.
Today the operating system is simply a shim between the hardware and the browser.
Does this mean that once a month its going to get all irritable and tell you to re-enter data 6 times?
There are bags of fertile/fissile material in the world. Enough for thousands of years of energy at today's population levels and with today's western lifestyle extended throughout it.
Currently all located in unsafe deposits that can and have leaked an awful lot of it in to the sea. Billions of tonnes of radioactive uranium in the sea.
It is our duty as custodians of the planet to dig it all up and turn it into energy and much shorter lived radionuclides that can be stored properly in vitrified matrices in steel containers where its finally safe ;-)
More information on nuclear...
...featuring those rare things: facts, logic, reason and sums...
one where nothing can live because of too many melt downs from nuclear plants that happened to be located near volcanoes, tsunamis, had too many Homer Simpsons working for them, or have computers running Microsoft software.
That's all right then, because none of the above represents a realistic scenario at all.

Re: The penny drops - renewables as 'The Answer'. ?
Mate, they ain't part of the answer. They are a major part of the problem. Introduction of huge swathes of wind and solar power causes infinitely more problems than they solve.
Indeed it is hard to see a single problem they do solve.
Unless co-operated with massive hydro, they don't reduce emissions. In fact there is considerable evidence to show that in cases of co-operating with certain types of fossil power, any benefit in reduced fossil generation is more than offset by the requirements to dump fuel into fossil hugely inefficiently to get high slew rate ramp up to compensate for little matters like the wind dropping, and sunset..
Intermittent renewables are an expensive cosmetic solution that does nothing to really address emissions at all. Its a make believe solution for politicians to adopt funded by generous rake offs from the consumer that go straight into renewable companies and from then it government ministers back pockets. That is its main function is not to produce reliable low emissions electricity, but to be give the appearance of so doing, for political and commercial profit.
Insofar as nuclear is an infinitely cheaper, less environmentally damaging, and more effective way to reduce CO2 emissions, Hansen et al are completely correct.
Of course, whether there is any need to reduce CO2 emissions is a moot point...but that is a step too far for Hansen.
If we want get from one side of the galaxy to another..

Re: As an intellectual and technological excercise...
Whenever you pour money into doing cutting edge stuff the chance to explore new untried ways of doing things occurs.
It doesn't HAVE to be military. But traditionally it oftens has been.
- Spread spectrum radio
- The integrated circuit.
- The internet.
- Nuclear power
- Early robotics
These are all ideas that got their first airing as part of defence programs.
Against that you have a few technological breakthroughs that are only partly associated with the military
The Laser - originally it was the Maser a useful thing for radar, but laser development was entirely civil up to star wars time.
Web applications and the like.
But these last would not have been available without te enabling technology of IC based computing and teh internet.
The military spend creates enabling technologies which are then adapted to civil uses.
And that is because military needs are civil needs as well. To carry a load of bombs a long distance in WWII large 4 engine bombers with extreme range were developed, They are in they end practically airliners - remove the bomb bays and add seats , pretty hostesses, and a pressure skin and there you are.
Accurate global positioning is a must for long range weapons. Its jolly useful for hill walkers in fog, too.
This isn't a justification for military spend per se, but it is a justification for targeted application of large sums of money towards developing technology that can in the end repay the investment a miillion times more effectively than simply keeping a few more people on the dole at a slightly higher level of comfort.
