Sounds very very exciting. Unfortunately it seems too vaporish still. For example, it specifies 2 kWh per module, but there is no indication whatever of the power delivery rate in kW. The power delivery rate of the Tesla entry is PISS POOR.
FCC: who the fuck does this serve?
80 GB per 12 hours is only 2 MB per second. On the face of it that wouldn't even begin to strain the slowest HD or SSD you could find, unless your data is EXTREMELY peaky/bursty.
I couldn't care less about the transfer speed. The slowest SSDs from yesteryear are more than fast enough - as long as they hold up in use (I'm looking at you, Samsung, the transfer speed collapsing to cripplingly slow after a while in use).
No, what matters is power-loss data protection. Both internal table structures protection, and cached write data protection. If it doesn't have it, it is UTTER CRAP and I wouldn't touch it. I see no information presented here that either level of protection is present.
Anandtech found that the M500, M550 and MX100 do not have the cached write data protection at all. What they have is a measure of protection against corruption of internal table structures - i.e., a half-assed level of protection; better than none but still FAIL.
I am worried that the BX100 and/or MX200 might not have even the half-assed protection - that they are no better than ticking time bombs.
Note that the large expensive tantalum capacitors of the M500DC enterprise drive give real full protection. The wimpy teeny tiny ceramics on the M500 do not. And most other brands are not even THAT good.
> THIS is why all this connected, internet TV stuff is NOT the future.
Wrong conclusion. The correct conclusion is that THIS is why the future our corporate overlords are presiding over SUCKS.
Wrong. It wasn't "commissioned as a cruiser". It wasn't even launched as a cruiser. The closest you're going to get is that it was designed and construction begun as a cruiser but converted during construction, and at launching was already a carrier.
If you want a title bar, you've still got it. The default is still to have a title bar. So this is an utterly pointless objection.
<blockquote>- 'router' or 'switch' - I forget, one routes packets by IP to the ONE PC it is for, the other just sends the packets to ALL connected PCs..</blockquote>
Incorrect. A switch replicates incoming packets to single SELECTED ports based on the addressed MAC vs the MAC of the attached device. A router redirects all incoming packets on the LAN which are addressed off the LAN subnet, to the WAN port (and vice versa). A NAT router (which basically everybody thinks of when you say router) adds rewriting the source IP/port-number pair of LAN packets which it redirects to the WAN, and reverses the process on responses from the WAN so they get to the right place.
You are thinking about a "hub", which simply replicates all packets coming in on any port, to all other ports.
To put it as simply as possible, a hub filters/rewrites nothing; a switch filters by destination MAC; a router filters by destination IP; and a NAT router filters by destination IP and rewrites source IP and port number.
Ahem, it is Shinano, not Shimano.
It is true that details were a closely guarded secret at the time, but with the passage of history all has become known in intricate detail.
See "Design and Construction of the Battleships Yamato and Musashi", by Kitaro Matumoto. Anyone who didn't buy this massive painstaking work when it came out in 1961 is not a serious historian. The main text is Japanese, but there is an English table of contents and appendix with copious tables and diagrams. From this we know such details as:
The exact dimensions of course[*]
details of 24 progressive designs leading to the final design
For secrecy the gun was officially termed Type 94 40cm, 45 caliber - actual bore was 46cm
Weights: gunnery, 11,802; armor, 23,500 tonns
The exact number of watertight compartments (1147)
The side armor being manufactured in 88.5 ton segments, 5.9x3.6m x410mm
The engine room floor area was 640 square metres
Superheated steam at 25 kg/mm^2 and 325 C from 12 boilers
[*] length overall, 263m; waterline, 253m; between perpendiculars, 244.0m
mean draft at full load, 10.86m
prismatic coefficient, 0.612
tactical turning diameter, 640m (heel 9 degrees)
period of roll 17.5 seconds
metacentric height at trial conditions, 2.88m
Mr. Matumoto defied an official order to destroy all documentation, saving voluminous notebooks.
Musashi did not have "36" 25 mm antiaircraft guns. That would have been an absurdity in 1944. By then she had 130 of them.
Unfortunately the 25 mm was a very poor weapon, especially compared to the excellent 40 mm Bofors on US ships. Musashi, like all Imperial Japanese Navy ships, was wholly incapable of mounting a credible AA defense.
As a USAian, may I say that the idea of rolling this back legislatively is STUPID DENIAL. Hello, all idiots with an R after their name: it DOESN'T MATTER what bills you pass to undo this, the President owns your ass! He will just veto (thank god). After 2016 it may be up for grabs again, but until then, JUST SHUT UP.
I am still in the elation phase over the FCC's action. Sure, it may turn into something bad, but you don't just abandon all attempts at governing because you're afraid your governing structure is going to be evil or incompetent.
In what world is FreeBSD limited to "intel/amd"? In the world I inhabit, we have:
ARM 32-bit: ftp://ftp.freebsd.org/pub/FreeBSD/releases/arm/armv6/ISO-IMAGES/10.1/
PowerPC 32-bit: ftp://ftp.freebsd.org/pub/FreeBSD/releases/powerpc/powerpc/ISO-IMAGES/10.1/
PowerPC 64-bit: ftp://ftp.freebsd.org/pub/FreeBSD/releases/powerpc/powerpc64/ISO-IMAGES/10.1/
PC98 and SPARC admittedly seem to have been dropped.
Apologies for not making proper links, but TheReg won't let me play with html until I've mae a billion posts or something.
Is that a picture of an S-100 memory card?
600,000 hours is a pretty piss poor MTBF. HGST 3.5" 3TB Desktar NAS is 1,000,000, and 7K4000 Ultrastar is 2,000,000.
It's perfectly obvious that 3D NAND has the potential to allow MANY TIMES more density in the package, so why in the nine hells do they reject 3D SLC out of hand? The rationale for having to resort to MLC crap in the first place has just been exploded. THINK.
Is stupidity an absolute requirement for running a corporation?
A stunning improvement. Never mind smaller but same quality - dig the massive improvement in quality for the same size.
I'm just a lowly user. I don't want to see WD swallowing HGST because WD is a shitty company that produces shit and will turn HGST products into shit.
As it stands now, HGST and Toshiba are the only drives I would willingly touch. WD and Seagate are both garbage.
It's an interesting experiment. Toshiba is advertising VASTLY greater endurance than anybody else in the class. The question is, is it real, or is it just optimism - less conservative spec parameters.
<blockquote>So the same should happen for bricks and mortar stores.</blockquote>
I don't think so. For a brick and mortar store the transaction is simple. For every transaction made at a particular store address, only one state and maybe one or a couple of local taxes are charged. It is a trivial matter to do the accounting. And it has nothing whatever to do with where the customer lives.
It is a different matter altogether for online purchases. You have to ascertain where the customer lives and keep track of 9600 tax codes.
See the difference?
The issue of sales taxes on internet transactions seems crystal clear on the face of it. Just say HELL NO DAMMIT to those 9600 state and local sales tax jurisdictions for online transactions[*], on the basis of simple insanity. If the brick and mortar guys cry about their business model, let them commiserate with the buggy whip manufacturers. And yeah, that would mean so sorry, states, "use" taxes won't fly so screw you and fix that shit NOW.
[*] If your online transaction happens to be with someone headquartered in your state/locality, then yeah, I don't see how you can wave away the sales tax(es) in that particular case. But I'm not talking about "local presence" bullshit; I'm taking about the headquarters location.
The fundamental thing that sets this apart from the Raspberry Pi and Beagle Bone in my eye is the SATA. If you don't need it, then you're not compellingly drawn to this board. But if you want to hook up an HD or an SSD for a specific reason, neither of the others is any good at all.
All the rest is just details. Yes, the CPU is ARMv7 like the Beagle Bone rather than the archaic Armv6 of the Raspberry Pi.
<blockquote>To make comparisons difficult, large amounts of power are given in TWHour/Year.</blockquote>
I'm not questioning this if you essentially say this is standard practice, but in what universe does it make any sense at all to measure power in TWh/y instead of the dimensionally equivalent TW?
<blockquote>waste annihilating molten salt reactors</blockquote>
That sounds so cool. Fanciful, but cool.
<blockquote>Oddly, non-renewable energy sources never run out</blockquote>
You are of course undeniably correct that at some point in the decline of supply it becomes economically unfeasible to perform the extraction. So yeah, nobody ever uses every single bit. In the extreme, they die first.
But you do understand the concept of FINITE SUPPLY, right?
<blockquote>They require a rare earth material which is in very short supply to create the super powerful magnets required</blockquote>
Sorry, but with all due respect, I don't believe you. There were electrical generators (and electrical motors) before Neodymium was even discovered, let alone refined commercially. No doubt the alternatives are not as efficient, so you get less electricity out. Essentially that means it costs more, but definitely not that it can't be done. You can also replace the permanent magnets with field coils, again at a cost in efficiency.
There definitely was no Neodymium in WW2 submarine electric generators, and they worked fine.
To answer the first question: no, and the second question: yes.
Endurance measures the amount of data you can write and overwrite. Retention measures the calendar lifetime of data which has been written. An SSD which is unplugged and sitting on the shelf is a time bomb. It's due to leakage. It's strongly temperature dependent, but leakage will inexorably occur even at room temperature or below.
It would be foolish to count on data retention for more than 1-3 years on an unplugged SSD. It doesn't have to be that poor, but there is a definite tradeoff between bit density and data retention. There are microcontrollers whose flash memory is absolutely guaranteed to retain data for 10-20 years. The use case there is very different. They are basically programmed once and then expected to operate without attention for a long time.
Not that even 10-20 years is particularly impressive. Good quality enterprise tape can match or exceed that.
In comparison, fresh disk drives which are written once or a few times and then unplugged will generally have their data perfectly intact and readable 5 or even 10 years later.
So in summary, though "stark raving mad" is a bit harsh, I would say "highly ignorant" is appropriate.
The breaking of the Lorenz teletype cipher due to the genius of Bill Tutte and others, notably Tommy Flowers' Collossus, as well as being the single greatest intellectual feat of the war, was a greater boon than breaking Enigma. The Lorenz network carried the very highest level commands. Enigma carried a lot of mundane drudgework.
I was pretty sure CPUs were things, and they sure are cleaning up on those.
I believe you will find that you can convert any amount of power to any amount of torque by introducing a suitable ratio of reduction gearing. I mean that quite literally. Any.
Put another way, 100 kW / 10 N-m can deliver exactly the same torque to the wheels as 100 kW / 1000 N-m. All you do is select a different gear ratio.
By the same token, you can reach exactly the same top speed using a 100 kW 2400 rpm diesel as you can using a 100 kW 7200 rpm petrol engine. All you do is select a different gear ratio.
Torque champions are not wrong per se. They just miss that it is torque at the wheel that matters, not torque at the engine.
What I don't do is spout a lot of uninformed hot air to try to sound clever.
Calling the Ferdinand Elefant a "hybrid" is just ludicrously ignorant. It was no more a hybrid than ordinary diesel-electric locomotives are, or the turbo-electric aircraft carriers USS Lexington and USS Saratoga were.
The Elefant had two gasoline engines driving electric generators wired to electric motors which drove the track sprockets.
In all these cases the electric drive was a simple replacement for a mechanical gearbox and power transmission system; no more and no less. There is no recuperation of energy on deceleration, no batteries to store electricity or cover peak demands. A hybrid is defined as able to obtain motive power from two or more sources. In all these cases, every last watt of motive power for the entire period of operation is obtained in real time from internal or external combustion engines and nowhere else.
"I'm not so sure this is a bad thing. Old tech is tested and its limits and abilities better known. Why do you think this is bad, technically?"
SRBs are unforgiveably STUPID.
SRBs for manned vehicles are CRIMINAL.
"Or maybe this time they will be built in a single piece - the only reason they were built in sections for the space shuttle was so they could be transported stupid distances."
Nope. Five segments. Sorry to tell you.
With all due respect, can it. This is by far the most illuminating site anywhere on this subject.
Maybe it's because they both make CRAP. Everybody knows Toshibas are much more reliable.
I bet PUIAS/Springdale's release beats the others as usual.
Bwahahaha! If you think RHEL7 will show up any time close to the first of the year, I've got a bridge to sell you. We'll be lucky to get the BETA within a year from its promised date of early 2013. And GA will not be before 6 to 12 months after the beta.
The birthing of 7 is going to make the drawn-out cock-up of 6 look mild in comparison.
I don't see anything in the documentation that indicates they have fixed the awful bug in KVM where a system with a Haswell CPU will no longer allow 64 bit BSD guests to boot. This is a really blatant and hideous bug.
"Good cannot exist without evil."
Balderdash. Of course it can. This may be presumptuous, but I have a hunch what you really mean is a whole lot closer to "Those who would give up essential liberty to purchase a little temporary safety, deserve neither liberty nor safety." It's not at all the same thing.
Funny, mine is a tall stack of failed and failing Seagates. Never lost a single Samsung or WD 3.5".
"With the main problem being the paying to keep it running. 2.35 megawatts at 10 cents per kwh would come out to a $2,058,600 a year for power."
Bovine excrement of the highest order. That is chump change. There are 69 million income tax payers in the US (http://wiki.answers.com/Q/How_many_tax_payers_are_in_America). This amounts to 3 CENTS each. A heavy burden - NOT. It's not even noticeable. It's so far below the noise threshold of national spending that it's not even worth one second of worry.
I also predict that your Moore's Law projection down the road is (1) outside the domain of what Moore's Law is actually concerned with (hint: it's not cost), and (2) it is nearing the point of becoming dramatically outdated as physical limits are approached.
Another thing that fairly leaps out of the numbers. The expense to run this item for its full lifespan (so far) is only 10% of the acquisition cost. It's less than the debt service on the investment.
Keep it running as a national resource. Don't even bother SELLING time on it; AWARD time on it to winning applicants based on interesting and useful projects.
Nope. Not me. Sorry, everything I order for next day from Amazon without exception gets here the next day on the UPS truck with a bright and friendly driver, packages always in excellent shape. Standard shipping is not much use though. More often than not they use some awful trans-ship-to-post-office service and it I rarely can check the post office more than once or twice a week.
Whatever HDNL is, it must suck to be stuck with it.
All right, specifics. Just what does Xfce NOT do? Today; not sometime in the past.
I'll tell you one thing Xfce does NOT do. It does not insult and ignore its users.
I also am enjoying CentOS6+Gnome2. But when CentOS7 comes out sometime in 2013 or early 2014 it will be based on Fedora 18 and you-know-what. I sure as hell won't ever be on CentOS7+Gnome3.
It is sad that, while CentOS packages KDE as an alternative to Gnome, it doesn't do the same with Xfce. You have to enable the epel repo to get Xfce. Fingers crossed they will see the light and package Xfce as an alternative to you-know-what with CentOS7.
(Yes, I realize, all these decisions are actually made "upstream" - in RHEL)
Just no. Unity was at NO TIME "making good progress". Its head was up its ass from the day it was conceived.
I would urge you to try an Xfce live CD or USB stick. Then please report anything you really need your DE to do which it DOESN'T do. I couldn't come up with anything when I did that. For now I'm in hog heaven with Gnome2 on CentOS6, but when that stops being updated I sure as hell won't be on Gnome3+CentOS7. Almost Xfce, either on CentOS7 or on something else.
The S1200 maxes out at 8GB. on a single channel. Why a 64 bit processor when it only has a bit more memory support than a 32 bit?
AC is just being a good nazi as well as a twit. Had he posted from an actual account I would not engage in ad hominem. As it is he deserves it.
"the fact is floating museums get gutted prior to commissioning. The innards are replaced with replicas, and they never reveal the entire works of the ship: certainly not the power plants"
Bull. The 16" guns, armor plate, and power plant are still in the U.S.S. Massachusetts and you can walk up and touch them. Not suggesting there is anything of strategic import in that ship, but your statement is incorrect.
