Best decision ever.
Taken a long while though - hope the major losses are confined to those not at the coal face
Well, I'll need a few dollars to research quantum computing, build working hardware, then I can start to crack the encryption to help you...
No I can't tell you if 'few' means a billion or 100 trillion...
I have just gone through a data refresh project - discs which were written and then filed in individual sleeves in a disc storage case, with silica gel left inside. Stored in a fireproof safe.
Those from 2005 are *mostly* readable. There was a ~5-10% failure rate, and those discs were looked after rather well. It is possible that the data was corrupt when written.
Unfortunately I am no longer in that role, and the 2001 discs were next on the list...
Slartibartfast: Come. Come now or you will be late.
Arthur: Late? What for?
Slartibartfast: What is your name, human?
Arthur: Dent. Arthur Dent.
Slartibartfast: Late as in the late Dentarthurdent. It's a sort of threat, you see. I've never been terribly good at them myself but I'm told they can be terribly effective.
Yes I know that Bezos is building towards bigger rockets, and these are already serious bits of kit. But the grasshopper was doing all of this several years ago - it was just using a lower peak altitude because it wasn't targeting tourism, but was a pure technology demonstrator.
There was a great infographic posted a few months back - pointing out that the Falcon 9 first stage could put a fully fuelled and loaded Blue Origins NS into orbit...
That's a colossal difference in capability!
This is a pure toy - there is nothing wrong with that, but any attempt Bezos makes to compare this with the Falcon is like comparing one of those kiddie electric ride on cars with a supertanker...
Sorry - missed this para:
"When I start my car on an average UK morning, the first thing I do is turn the heating full on for a good 15 minutes. In the winter, it's front and rear electric defrost for a good 10 minutes and 50% heating/demist all the time. In the summer, I have the aircon running. I have a feeling that these conditions would invalidate the mileage range claims for any electric vehicle."
Err - it's plugged in, so all you need to do is tell it you'll be driving in 15 minutes, and use the mains feed to preheat the car. Easy. No cold running engine either...
"If you're thinking of repairs, please turn your attention to the battery pack. Never take your eyes off the battery pack. Battery pack. It's a 'Lifed' item. Clock is ticking."
Yes - it has a life - so do all the components in an internal combustion engine.
The battery was originally quoted as a 10 year predicted life. Since they have had a few being driven around that has now been revised Upwards as a result of the telemetry data. It's now 12 years.
Oh and that's when they have 80% charge capacity, so they are then useful in all sorts of other applications - probably static, and then they can be recycled into new batteries.
My car has just died, it was 11 years old - The engine is dodgy, the gearbox is a bit wonky, the brake lines are corroded - it's had various mechanical failures....
But a 10-12 year battery life doesn't seem so limited any more.
"The average automobile engine is only about 35% efficient, and must also be kept idling at stoplights, wasting an additional 17% of the energy, resulting in an overall efficiency of 18%. Large stationary electric generating plants have fewer of these competing requirements as well as more efficient Rankine cycles, so they are significantly more efficient than vehicle engines, around 50% "
"Total losses: 1,423.5 MW (2.29% of peak demand)"
80-90% (theoretically 92%, but who gets that)
So even ignoring:
- Nuke plants
- Regenerative braking
You get 97%*80%*50% ~40% efficiency from an unrefined, centrally delivered fuel as opposed to ~20% for a highly refined and locally distributed fuel.
I wonder if "on a mobile device" covers applications on a drone?
that if you buy more than a couple of desktops the price comes down to something a little more reasonable.
1k/year is an awful lot for a system that could probably be set up in house for not much more than that (assuming that clients need to be added on in either case)
"On Dropbox? Really?"
I really didn't expect that the joke icon, or the </sarcsm> tag would be necessary. I overestimated the humour detection of commentards...
The point being that we can fairly easily defend a small piece of information against data loss.
and a copy on Dropbox, and you'll be fine....
Does this refer to losing the keys as in "I lost my house keys and now I can't get in", or "I lost my keys, and now Eve can impersonate me".
The first of those is pretty easy to defend against...
"I once Ghosted a blank drive over a client's hard drive instead of the other way around - oops."
I have seen a RAID controller do that automatically...
Mirrored disks, one fails - alarm goes off, everyone carries on.
Pull it out, all good.
Pop in a new disk, all good
Array starts churning, excellent - copying data from one to the other, tea time.
Erm, where are all the files?
Why do we have two disks with identical unformatted data?
I'm sure you can turn it off - or just run your own CA - and install the root...
"I would tend to agree, although in corporate environments the only root CA the clients need to trust is the in-house root"
Yes - although most companies don't MITM certain traffic (like banks etc) - they recognise that that would be seriously unethical.
Hence my "public" CA for these devices, which would be well known and only valid within an RFC1918 domain, and potentially not even across routers. The idea is a limited mechanism for those connections to be trusted - which will satisfy home users, and will allow corporate users to get a proper cert on there easily.
Surely no need for it to do so though.
There is of course the question of what you are trying to do with said cert:
Why not have a "public" root CA which anyone can sign their "self signed" cert with - but that is only trusted on RFC1918 devices
After all - I suspect we're looking for data encryption, not authentication for these devices. You could even use the MAC address as part of the cert, and validate the connection against that as well (no routing allowed)
"True enough; but if your trading algorithm really works, you can get the same result in time by just leaving it running."
Not if it is time limited - and if you can leverage 1000 times more money that you have available, then you can jump start yourself very fast indeed...
You can then invert that into your own scheme, and get 90% returns (assuming that the Quantico service is actually providing things like the high speed links that you don't have access to)...
You get 10% of the return on someone else's money.
Not just one "someone else" either - as many as think you are good at your job.
That could be a 10% return on much more money than you can risk personally...
"Back to the story, it seems to show a setup where each house has a local server and storage more than computers connected to the Internet and uploading everything to four giant US companies."
From the story itself:
"The tank is a big buildin' full of all the facts in creation an' all the recorded telecasts that ever was made—an' it's hooked in with all the other tanks all over the country—an' everything you wanna know or see or hear, you punch for it an' you get it"
That sounds like a few interconnected data centres to me...
"I haven't seen any ads showing blokes. I saw th ad with a woman and just sighed. If you want to appeal to women to join the tech industry, why do you think this would attract them to the profession? Again, why would showing a sizzling hot stud attract men to the industry? Now, if you should men and women with their pockets loaded with dosh, looking happy and successful, that might work."
Maybe the women are there to attract the men and viceversa?
Maybe not everyone is motivated purely by money?
It's generally shock heating - i.e. heating due to compression.
Meteors are generally fast enough that the air just can't move out of the way
Is it just me or would others not activate this and want as much data as possible to be instant telemetry, rather than waiting until it's over before downloading it all?
If it goes "unexpectedly" then you at least get some data...
The Daily WTF
Only if it's not plugged in...
WORM media has many benefits, and backups are one seriously good case for them
Now they do, rather than Amazon being the only ones...
I still don't...
"@John, I'd agree that your own, custom designed system will be a harder nut to crack, but the key issue here is that we're talking about volume produced products which are given to people who don't understand the very basics of security, usually because they're Joe Average - it's only us with our warped and twisted minds that immediately spot the inherent problems :)."
Yes - the custom nature makes it much easier - but actually the internal security doesn't need to be that complex. It's the remote access that's harder.
You could have matching internal security all of these things - and actually you could have fairly matching *external* security...
The value of the attack on each of these is still far lower than the cloud solution.
Obvioulsy having strong internal seciurity makes life better still, but reducing the value of each target makes a significant difference.
There's no need for it to be cripplingly expensive - I have a rasPi which runs as a security camera (and associated IR light), and controls (visible) lighting and secure access to my garage (rather nice when it's wet and dark).
Functions which logically hang together, and can be easily run by a very low power and low cost system.
There is an scp based data uplink to a hosting account under my control, so that security footage isn't lost in the event of an intelligent thief...
The security hole needs someone to break my VPN, then break my SSH key into the Pi - I reckon by that point they can figure out which pins to toggle on their own...
The reward is fairly low - one garage with some tagged cycles...
OTOH a commercial cloud based system has a much higher reward - Look I can see when any of these 100k people are out and unlock their door. Easy.
I'd like to run some digitally controlled TRVs and have that all handled by another RasPi.... But that needs to wait for a little while...
Actually having those things working together is quite nice - but it doesn't require any external connectivity.
Open the door at night and have the lights come on...
A delivery man rings the doorbell, and your phone rings so you can talk to them, despite being at the school gate/shop down the road...
The issue is external connectivity, not that things can work together...
I think it rather depends on :
a) how often you ask
b) how you ask
c) the context in which you ask
The prime advantage of an iPhone is that they are readily available - and self contained. No need to get an extra screen and keyboard as well...
more importantly - it looks like the technology on those readers hasn't improved much...
What can you do to defend against a printed fingerprint? Look at vein structure and heat as well?
I did specify lab testing..
We used to do this at a previous place of employment - we'd run simulations etc, then we'd test on the real world. But we'd do so in a non destructive manner (fairly easy, we were testing torrenting performance, so we contributed as much as we could to the swarm)
They replayed an old set of data into the system in a lab...
This is a *good* time for the failure to occur.
In (lab) testing I want them to fail - and this is what happened here.
They tested against a known large load - and it fell over. They tweaked it and now it doesn't
That's the point of this testing...
We all pay taxes for things we don't use.
Some people don't use the health service much, others don't trouble the education system.
Some don't ever use the jails, or the rubbish collections...
That's kind of the point of taxes...
The BBC tax is somewhat anomolous because it is a flat rate - it's a per household tax, unrelated to income or wealth (at least council tax is related to the value of your home, so some loose indication of wealth)
Is this going to do the old BBC thing and charge if we watch itvPlayer?
a) lidar still needs to be able to see the sandbags - which it did, but only after trying to make two lanes out of two.
b) the car has been programmed to ease traffic flow - that does mean asserting priority at times, else the whole system shuts down...
So it understands priorities and common behaviour (in this case making the lane into two lanes on approach to a junction is apparantly common practise, mostly because the American't can't paint - or don't stop at red lights... ;) )
So it started the two lane manouvre, as would a human, then had to stop - and pulled back into a gap in the traffic. Note that the traffic was still in it's own lane - so it could reasonably determine that it had priority in this situation. The bus driver either assumed it was parking or didn't give a monkeys about priority - we'll probably never know which.
Very much in it's infancy, yet already with more experience (although possibly less varied) than I will ever have.
And the failures are where self driving cars can really come into their own. They can and should have redundant systems, so they can simply drive themselves to a local service centre and get a replacement fitted - or, if they are seriously compromised, just stay put.
As opposed to the small majority of cars driving around at the moment with failed lights - their drivers know they have failed lights, they just don't care.
Yes - they're testing it in the wild...
OK - the wild isn't a particularly difficult place weather wise yet...
But the car would be far better than you at seeing around the corner - because it will slow down on approach...
It will be better than you at fog/rain because it will have more sensors, operating at different wavelengths, than you do.
It will be better than you at night, because it won't be tired.
It will be better at dealing with potholes, because it will "see" them all, and plot a course around them - or correct the steering faster than you could.
The Google car tried to create two lanes of traffic when only one was described by the road.
- This was because of the wierd turn right on red rule, it was probably indicating right.
It then got stuck behind a stationary obstructon - the lane wasn't as wide as it looked.
When traffic started flowing it then went to merge with the traffic as a gap appeared.
The bus driver, in the same lane, drove their bus into the GooCar.
I suggest that the bus driver may have thought the Lexus was parked/parking if the right indicator was still on - else they should not have been trying to pass a vehicle in the same lane. Ideally the Lexus would have been indicating left at this point of course.
There are cars parked along that road in the streetview linked by a previous commentard.
As for their safety record - they have driven far further than the average driver ever will - and each time any one of them encounters an 'interesting' situation they *all* learn from it...
That's far better than the current situation...
After all how many people get killed by drivers each year?
30 thousand a year in the USA, another 2k/year in the UK
That's not a particularly high bar to exceed - and the advantage is that the "drivers" will get better over time, they won't develop sloppy habits, get tired, read an SMS, be cross with the kids in the back. They don't have "blind spots", they don't have tempers, they don't start sneezing.
Almost certainly deployed at 602km, but still travelling "upwards".
"Last time I looked, the relationship between Win10 (on real PCs) and Win10 IoT (on embedded devices) was similar to that between Windows NT (on real PCs) and Windows CE (on embedded devices)."
Yes - I know that.
My point is that it might not be a bad thing to have another OS available.
Occasionally it's useful to be able to fire up a windows VM - for whatever purpose.
I'd not mind having a Win10 minimal (or whatever they call the low end Win10 desktop) on a spare SD card. Win10IoT seems utterly pointless anyway, RasPi or no RasPi...
It might be - but actually I wouldn't mind being able to throw a Win10 SD card into a Pi3.
I'm sure there will be "windows only" things that my kids come home from school with, so having an easy "pop this SD card in, machine will connect to the dirty network, do windows stuff" would be useful.
Of course the work will get sent back as a scanned photo of the work on a wooden table, embedded in a libreoffice document...With a note saying that it really should be possible to do homework on any PC...
It may well be out of print - only took me a few minutes to find the pdf last time..
With so many rocket fuel stories should the editors be linking to the rather excellent book "Ignition", as recommended by a fellow commentard a few stories ago?
"That said, they have access to far better market research than I do, and their earnings appear to vindicate them."
They at least say that the choices they are making aren't disastrous. But we can't tell if they might be better still with a range of device formats.
I have a broken 4S - bought from fleabay - simply acting as an SMS/iMessage gateway because they couldn't be bothered to support SMS in the SIM equipped iPad (and I prefer to use the iPad for SMS than my phone)
I suppose that makes it a *good* decision on their part...
The 4S won't see upgrades, but since it does absolutely nothing other than act as an SMS relay (with a prepay SIM) I'm not fussed.
If they ever make an iPhone that I am vaguely interested in then they are likely to get another sale - but the current range don't cater to what I want in a phone - at all...
I can't imagine that I'm the only person who has similar requirements/desires - I'm happy to be niche/unusual/odd, but I doubt I'm unique... (I'm not rich enough to be eccentric).
Then I can tell Apple what *I* want.
Since I use a tablet for things that need a larger screen I don't care about screen size or apps.
I care about battery life, making calls, and some SMS (iMessage relaying preferred).
The other requirement I have is that my contacts get synced onto the phone for use in aforementioned calls...
"Oh, and changing th iCloud password is a good idea. It prevents an accomplice deleting data."
Do you really think that Apple deletes data when you ask for it to longer be on your cloud storage?
