The Amiga was not only first, it was still the only multitasking OS on the desktop in 1990. Windows didn't support co-operative multitasking until Windows 95 came out, and if I'm right neither did the Mac.
Google and Backblaze are not typical enterprise deployments. Each company has built what is effectively an entirely in-house proprietary SAN with a large dedicated team to maintain it. Regular enterprises, ie people who are not in the storage business, cannot do this.
FYI 15000RPM SAS drives will provide significantly more IOPs per disk than 7200RPM SATA drives. Depending on the application, that may be important. The firmware on SAS drives also tends to be tuned for heavily random workloads, and for operation within a RAID array. Cheaper SATA drives come with a shorter warranty and conditions on how frequently they are in active use. Outside of these, yes the drives are essentially the same.
I suspect SSDs will eliminate most of the remaining business case for deploying SAS drives in the near future as the cost per gigabyte continues to fall.
I understand that the standard motor is replaced with a smaller one on the AWD P85, but I take your point.
it's probably as much, or more, to do with the fact that electric cars require less energy to travel the same distance.
I worked out a while ago that a standard petrol car needs about 1.3kWh/mile, based on the energy content of petrol (gasoline) and a typical gas mileage of around 33mpg. A Nissan Leaf, on the other hand, expends about 0.25kWh/mile. The Tesla Model S is a bit more energy hungry, but it is also a much larger and heavier car with more toys typically installed.
This is before you price in the other consumables that petrol cars have in terms of servicing - oil, oil filters, fuel filters, air cleaner filters, spark plugs and time for a mechanic to deal with each.
On the other hand electric cars have the issue of the battery deteriorating over time.
The difference between the 60kWh and 85kWh Tesla Model S cash price is $10,000 or $400/kWh so I'm not sure about the article's conclusion that the battery costs $300/kWh.
The Nissan Leaf's battery is closer to $300/kWh (based on comparing the price of a Leaf with the Flex option in the UK, where you buy the car and lease the battery separately); but there appear to be various anecdotal concerns about the Leaf's battery longevity. Tesla's design includes an active battery cooling system, whereas the Leaf seems to be passively cooled, and this is leading to the battery capacity on a full charge dropping rather faster than would be expected over time.
Despite this I think the conclusions are right - Li-Ion battery can only continue to improve, and if any of the several proposed methods of improving the technology are made to work they will get considerably cheaper soon. I think electric cars are here to stay, and it's a good thing.
I went for a quick look into this. Wikipedia reveals that Virgin Australia is owned by Virgin Australia Holdings, which in turn is owned by a consortium consisting of a number of other airlines (Ethiad, Singapore, Air New Zealand), plus Branson's Virgin Group with a 10% holding.
Virgin Mobile in Australia, much like the Virgin broadband/phone/TV operation in the UK, is no longer anything to do with Branson - he sold it to Optus in 2006 and that company is currently wholly owned by Singtel. In the UK, Virgin Media is owned by Liberty Global.
This reveals how, these days, Branson really does business. Virgin is basically nothing other than a brand. It's a respected brand - funky, hip, cool, relaxed, and so on. But that's all it is. Branson isn't really an entrepreneur. The way I think it works is that people with a business idea approach him, put up their own capital, and ask for the use of his brand and his personal involvement as a promoter. In exchange he receives a generous shareholding of the new company - which, if the company is successful, he later sells. If it fails, those who put up the capital are left carrying the can.
And Branson will lose any such competition.
The vast majority of Branson's business ventures have been failures. The places where he does well are in monopolies, such as international airline travel and running monopolized train services in the UK (Branson tried to run a regional airline in the UK called Little Red, but failed). Even then these are on shaky ground; Virgin Atlantic has only just begun to return to profitability, probably something to do with Delta taking a 49% stake in the airline over from Singapore Airlines, and he nearly lost his rail franchise, until his lobbying efforts revealed that the UK government had made mistakes in the allocation of the contracts.
The only reason why Virgin Galactic even exists is because the state of New Mexico ponied up massive subsidies (thanks to Bill Richardson) to build the thing there. Branson never risks his own capital on long shots. He's only involved because this is a way to create publicity for his brand. Likewise his Formula 1 efforts, and likewise this nonsensical idea that he has people building an electric car.
Branson is all showmanship and no substance. He wants people to think he is some sort of environmental activist as he believes it will benefit him and his company. You'll see - we'll never see or hear of any Virgin-manufactured electric car ever again.
Hats off to the guy - he's made himself a lot of money (nobody knows how much, though) - but excepting his long-past days in the recording business, he guy has never delivered a manufactured product in his life, and never will.
Being forced to open-source their largest software project is a quite conceivable (even if unlikely) outcome.
It's neither conceivable nor likely. VMware includes a lot of very, very clever technology. (I note in VMware ESXi 6 that they can now do fault tolerance with 4-way SMP. FT, for those who aren't aware, means that two physical servers between them can keep a VM continuously available even if one server fails.
It sounds to me as if VMware are prepared to contest the matter, which comes down to whether or not a court will accept that VMware have complied with the terms of the license.
The most likely outcome is that they will settle out of court. That will, most likely, involve an agreement to pay the litigant's legal costs, and some sort of time-bounded agreement to modify their software in such a way that it no longer breaches the GPL.
Virgin is a wealthy company backed by a very wealthy man.
And, according to Tom Bower, $200m in subsidies from the state of New Mexico, courtesy of a starstruck Bill Richardson.
Branson's core businesses are built around operating monopolies and extracting subsidies from governments.
Rossi's time in prison was due to uncleared allegations of tax fraud and toxic waste mishandling [wikipedia.org], which even if true would have little to do with this story
He served time for them so they probably are true; and yes, this has everything to do with the story. This man lied to the government about his tax liability, and apparently lied to everyone with a false claim to convert toxic waste into oil.
Occam's razor sometimes shows that the seemingly improbable is actually the most likely explanation.
LOL. No it doesn't.
Occam's razor says (as a very basic summary) that in the absence of evidence or specific information, the proposal that requires the least assumptions is probably correct. Or, more conversationally, that in the absence of any better ideas, the simplest guess is probably the truth. The simplest guess here is that the guy is a fraud. The non-simple guess is that the guy is not a fraud and that our understanding of matter and energy to date (which is based on a huge body of actual scientific measurement and observation) is all wrong.
I think you are confusing this with Spock/Sherlock Holmes say that when all the impossible proposals are eliminated, the one remaining, however impossible, must be the truth. That's a good maxim to live by; the problem is that we haven't eliminated the possibility that the guy is a fraud.
I can't think of a single good technology that originated at Sun
ZFS, dtrace ?
On the contrary. What we have in filesystems at the moment is fragmentation.
We need people pitching in with stabilizing and fixing one major FS in Linux. It looks to me as if that should be btrfs.
Back in the day, the cutting masters from which LPs were pressed were inferior (the sound had to be modified to make it fit on the LP - longer tracks had to have their levels cut so that the track pitch could be reduced to enable them to be pressed). There is absolutely no way any objective person could believe that the compromised masters, which were modified in order to fit on vinyl, were in any way superior to the clean digital copies - except for pop music which was exposed to the loudness problem.
These days I would have assumed that the same problem would exist so I don't get this about modern LPs at all. If I want the sound of an LP I'll listen to a CD while scrunching a packet of Rice Krispies next to my ear.
