Re: 3.669 per cent of the maximum velocity of a sheep in a vacuum in Reg units
However, you still need to put the decimal in the correct place... two to the left!
=> i.e. .03669% of the maximum velocity of a sheep in a vacuum in Reg units.

I still don't see it as a valid attempt to compete with SSDs using Ye Olde spinning rust. In case you haven't noticed, the head count matches the number of platter sides. Dual actuators with only one set of heads per platter should NOT double the cost, but SHOULD at least double the throughput from a similarly sized drive. WIN/WIN
One of the problems with the Conner's dual servo drive was vibration. The opposing arrays each covered all of the platters' sides. The Bernoulli Effect isn't powerful, yet, it's powerful enough to induce vibration on the platter. With multiple heads on the same platter sooner or later a resonance can be induced significant enough to crash of opposing heads. Long term reliability was NOT good.
Seagate uses separate servos and head arrays for different platters to sidestep much of the unbalanced asynchronous force inducing vibration and may be much more reliable. The dual servo action rather reminds me of scissors, which might also reduce unpredictable vibrations. (If they can be predicted, they can be compensated.)
I see no reason for RAID1 - I'd prefer a separate drive for mirroring. While an enterprise might want the dual servo arrangement for more I/Os, that's where Flash rules. For archival purposes, however, sustained SATA3 speeds from near SATA2 technology can speed backups and halve rebuild times for (hopefully) a modest increase in the price of the drives. Would you rather have a ~12 to 16TB drive read in nearly a day, or maybe only a shift?
is in the path of totality, though a bit on the edge. However, I'll be volunteering with a few of my fellow amateur astronomers at the:
Homestead National Monument of America
We're only 4 seconds shy of the central path; ~ 2 minutes 31 seconds of totality for us. We expecting maybe 8,000 people... but Gage County bought 20,000 "observing glasses".
I'll be projecting an image of the eclipse on a white-board with my home-brew 8" f/5 Newtonian in a Dobson style mount with a 2" 30mm eyepiece. Totality will be very near Zenith and the 2.5° True Field of View is sufficient to let the eclipse drift though during totality without touching the undriven mount.
Other can take take pictures and videos... but I plan to enjoy totality and such sights as the "Diamond Ring" and the "String of Pearls" with a pair of Mark 1 Eyeballs for the FIRST time!
My 20+ year old HP LaserJet 5L (upgraded to 9MB) is still alive and kickin' many boxes of documents later. I admit Ye Olde Parallel interface isn't the most convenient to use with most modern kit; but there's no reason for my home office to throw money at "new & shiny" when B&W documents are desired. Because HP avoided cheap plastic in critical components it's still serviceable. Brass Gears Matter!!! ;<}
I'm not a gamer, nor in the market for Zen... yet. When I need a couple more cores to keep most of the the 32GB ECC (unbuffered) RAM, 10 SATA3 + 6 USB3 ports, and 4 PCIe3 slots busy (SABERTOOTH 990FX/GEN3); I'll swap the FX6300 for a liquid cooled and somewhat overclocked (~4.5GHz?) FX8370e. Primarily for storage with an occasional compile, and maybe a VM or two, it does yeoman's duty - thank you very much AMD! It's EVGA Superclocked 750Ti is more than fit for purpose for the user side - while a Geforce4 64MB chugs away in the PCI(no e) slot as the Console. (Presuming it lasts a few years longer a Zen+ is in that box's future.)
There's no rush, but a Raven Ridge APU will be a fine foundation for graphical workstation late next year. Ye Olde 1.6GHz 4GB dual 64bit Athlon (RS780) AIW is currently sufficient for web surfing so long as NoScript blocks most of the useless CPU Cycle Thieves.
The one lung "Walmart Special" (Compaq) 2GHz 32bit Athlon upgraded to 1GB RAM with the Radeon Xpress 200M (1150 chipset w/ATI Radeon X300 GPU) is getting a little tired. A "lightweight" OS like AntiX works fine, but the graphics are weak. In a laptop I'd like an APU with HBM2 to assist the graphics and plenty of ports. Even just 8GB of HBM2 with no DDR4 would be sufficient, though mobile APUs with HBM2 probably won't arrive till '18 or later. An additional battery draining GPU need not apply at it's endurance for hobbyist Astronomy and Amateur Radio applications rather than gaming prowess that I'm wanting. ;-)
Do you visit any web sites with a FB icon, DougS? Do you have no anti tracker software like Ghostery or Privacy Badger? Do you allow advertisements to display and scripts to run? FB gathers data on EVERYONE THEY CAN, (complete with facial recognition and any other date they can gather). Your choice is irrelevant to their business model - people are just consumer information to sell.
You have a FB cookie that follows you everywhere that reports what you do... whether you've ever chosen to "join" FB or not. You have no effective option to avoid their data collection unless you enable inhibiting software on your own.
The "opt out" option offered by FB requires registration and acceptance of a permanent cookie that FB pinky swears they'll honor. Good luck with that!
EULAs are worth less than the electrons to send a "click". If a company isn't willing to pay for a written agreement process, then a short universal public agreement favoring the consumer should have to suffice. The needed tort reforms would not allow attorneys to get involved in the process otherwise. If a company wouldn't agree to the public protections; then the required written agreements demanding the attorneys involvement will price them out of the market - except for the most lucrative of products and services!
First, software patents should be invalid - particularly the "do it on a computer" and "do it in the cloud" variations.
Second, software APIs should never be considered as a valid method of Copyright and all public facing interfaces must be fully and publicly documented.
Third, the software's license type should impact the liability of the provider, vendor, and developer:
A(ble) copyleft open source type of license (i.e. GPL) would be the most difficult to receive damages for and the safest for developers and vendors, though not as remunerative in and of itself.
B(asic) [B(uilder) or B(usiness)?!?] copyright open source license (i.e. BSD) would more often be the middle ground - but only so long as source code and APIs are provided and documented. This would be riskier but there's plenty of room for "special sauces" mixed with closed proprietary code.
C(rap) [uh, C(losed) or C(ommercial)] proprietary licenses would imbue the vendors and developers with the most liability - with criminal as well as civil penalties. Big risk for big bugs are potentially a boon; yet may often be economically nonviable. Volkswagen C level executives would find life a whole lot different for awhile... but the software engineers could reduce their own liability by refusing to perpetrate fraud, (presuming management didn't have software modified elsewhere).
D(ead), D(eniable), D(eactivated), D(angerous), and D(umped) software might be thrown together into another category altogether. If a company isn't will to support the software, (especially on the machine originally deployed), why should they be allowed to profit from said software anymore? If a company is not willing to fix bugs, (typically for a fee for abandonware), then pertinent code should be released. Definitively as "use at your own risk" category. Perhaps closed proprietary code should be held in escrow to be released after a period of time?
"Fit for use" may still be applicable. Many (most) D(igital) R(estricton) M(anagement) methods need to die a horrible death, and their disabling or removal should be required following the death or disability of the pertinent business(es).
IME with AMT - a built in corporate hardware back door for the government pirates under intel's control.
Now, if we could only manage to find or steal our own key we could control the hardware we bought and paid for before the situation gets worse. When the criminal element hacks their way in and join the party, every one else walks the plank with no where to go for help but Davy Jones' Locker to beg Calypso for a boon!
It's just as well you're not a yank. Yes, there's a small minority of of rank and file cops acting like thugs. However, there a lot more politicians, their moneyed backers, bosses, media, and "social justice warriors" playing the role of rabble-rousers and behind the scenes manipulators toying with their ofttimes violent "sheeple".
Tend to your problems at home. You're more familiar with the local situation and better placed to handle challenges nearby. The world is in for a rough time for a while. It would be nice if most good people in cognizant active agreement with more modern morals survive to preserve civil behavior, rights, and liberties. Many others who haven't been raised, are unwilling, or perhaps never had the opportunity, to appreciate them might have some semblance of a chance at a better life. Maybe then we can all be better able and willing to put forth the effort to achieve it.
A word of caution though. It's going to take more from you than acting the part of just another Anonymous Coward to achieve positive results. It will be necessary for you to take responsibility for your own actions... or lack thereof.
the back story. All is NOT what it seems where money and politics are involved! Fishing expeditions are a great political tradition; especially when backed by lobbyists for big money and free advertising chasing bigger bank accounts. There are no "Good Guys" in this game - only winners and losers.

Guessing at Verizon's distance between towers and the power required I am NOT getting close to those 5G transceivers! With Interstate Hwy 80 ~50 miles away I expect the boonies to largely be served as few by as few 4G towers a they can get away with.
... but the affordable satellite bandwidth has already been allocated, mostly to (MUCH more densely populated) California.
Californians needs their comforts, and, it's so ex$pensive to live there. Cable, ground wireless, DSL, or cellular might crimp their budget. Meanwhile, I've friends with dial-up here in parts of Nebraska. Their only other option is a dedicated satellite T1 link for BIG BUCK$.
I'm more fortunate living in a shrinking metropolis of ~4,000 70 miles from Lincoln getting an honest 12mb/0.6mb(1.5mb with a better DSL modem). A ~100mb service is "available"; but that's a few poles too far. However, I'm upgrading to next week to 25mb down for <$90/month (including phone, long distance, taxes, service charges, and fees). Owning my own modem $ave$ me the rental fee. Time Warner is an option I avoid. I'm too cheap for cable or satellite. (Eventually I'll add VHF Hi/Lo & UHF TV antennas to keep my VHF/UHF DX200 vertical and G5RV dipole SW Amateur Radio antennas company.) I also appreciate a landline capable of functioning when the power is out - if the wires are still up. ;<)
I'm off to visit microwatt valley with my flippy phone in the pocket (voice & text sometimes work near the hilltops, but not much else), and let them know the news of a possible broadband connection... possibly by the next decade. (Verizon 4G is more likely than satellite as 3G coverage will be replaced before 2020 and a few more towers will be added by then. ;<)
So true. That's the reason I seldom observe with my 8" Newtonian when "Ol Sightblinder" is near full. A slender crescent is best to better detect tiny peaks and crisp craters.
An OLED display on a tablet or phone I can adjust to (what most people might call "ludicrously") faint levels would be nice. Few people have any accurate conception of true dark adaptation.
For deep sky observing, a monochromatic red mode too faint to perceive color without the necessity of red transparency layer(s) would be a boon for Sky Safari Pro. ;<)
I believe reusing a booster has been proposed for an upcoming launch for an Indian satellite. With a few engines to cherry pick from and relieve some storage space, hopefully they'll choose some good'uns!
The customer definitely does get a nice big fat discount for taking a chance... but it's not free. ;<)
It's too bad you're not convinced and pay so little attention to fuel usage. Geostationary satellite launches are by far the most difficult. Yet, BOTH satellites were able to successfully attain their respective orbit. It was expected that the sea "landing" would be iffy... a return to land was impossible due to insufficient fuel.
"Looks like early liquid oxygen depletion caused engine shutdown just above the deck "
What's interesting is that the landing was so "close". A satellite launch to geostationary orbit requires a much higher velocity of all the mobile launch system components, including the first stage. As a result the reentry temperatures are far higher than would be expected for a low orbit launch. One of the worrisome potential problems was thermal damage induced by the extremely high reentry velocity required by the geosynchronous satellite launch. If little enough damage was done by the extreme reenty heat that the launch failure was due "early liquid oxygen depletion" that actually speaks well of the first stage's overall performance!
If Ethernet doesn't get in gear with economy of scale we'll be stuck with a proprietary one size fits many solution in the mass market and a sky high price for anything more!
Thunderbolt 3 may serve as a prod. We don't really have the software for a good 10Gb *IPoTB hack, yet. However, IPoTB is already integrated into OS X Mavericks. How much more would it take to add the functionality to the other Unixes, Linux OSs, and even (shudder) Windows?
The Asmedia USB 3.1 controller runs ~ 3$ vs intel's ~5$ a port for Thunderbolt 3 (in quantities of ~5000)... plus a USB 3.1 cable. Ethernet's longer cable run than Thunderbolt's 3m (copper - 60m optical) would be a nice bonus and handle bigger networks at what should be a lower co$t per port. Look at the way Gb Ethernet has become so nearly ubiquitous. ;-)

"These chips are workstation chips, not gaming chips, unless you've got excess money to throw away for very little benefit."
Gimped "workstation" chips without V-PRO may not be a disadvantage, except at larger companies.
However, MY definition of a true "workstation" includes ECC RAM, online RAID(10 is usually sufficient) main storage with multiple offline images with incremental backups.
YMWV, but it might take only one flipped but to lead to an ex$pensively bad day that could co$t million$... or even live$. If you want an Intel based workstation do your homework an buy an appropriate Xeon based system - it might even be less costly.
If some ignorant fanboy is desirous of e-peen bragging rights; it's their money. In an environment where multithreaded programs, verification, and speed - where the occasional reboot is no big deal; a "PC powerhouse" may be a valid choice. I'd rather have a true workstation with functioning ECC RAM than a "PC powerhouse". YMMV
"small tethered black hole"?!?
Not on THIS planet Buster! Some of us are here in Reality... Get Your Virtuality OFF MY LAWN!

the 1890s would be a more appropriate lesson for historical purposes.
A battle for a .gay TLD without the LBT seems rather exclusionarily *cough* sexist, and more about the MONEY - no matter how desirable for political correctness! The .lgbt TLD is too easily blocked to an extremely large portion of the world's population due to undesirable connotations in many countries... especially those predominantly Muslim.
With .gay visibly promoting the 1890s and light hearted feelings, perhaps the more sexual interpretation can occasionally slide under the censorial radar.
Yet another similar TLD just isn't needed to add to the confusion. Adding .biz to compete with .com was bad enough, though arguably justifiable; it's all about the money. The .lgbt TLD should be sufficient... for now.
and even the .380 becomes a viable defense option - for those of us who choose to accept the responsibility; and are still allowed to defend ourselves with a firearm.

$1,350 is too rich for my blood, and IMHO one round is not enough! I'll keep my Smith & Wesson Bodyguard. ;<)
Given time, avoidance and 911(or equivalent) are still the best options. However, much of the time some means of defense is required to buy the time. All too often less than lethal options are insufficient. YMWV
"at 18,500mph, or 0.2759 per cent" - You're missing two of them.
0.002759 per cent or 0.2759 hundredths per cent of the maximum velocity of a sheep in a vacuum would be a bit closer to the mark.
I know, it's tough sticking the decimal in the correct place. The teacher called it "Dimensional Analysis" as part of "New Math; which sounded like a real eye glazer when my class learned that trick way back when... in Fourth Grade. Unfortunately here in the states they're trying to make Elementary Mathematics even more obfuscated with "Common Core"; too often taught by those who have little understanding of Mathematics. (sigh)
on a dinosaur single 2Ghz CPU 1GB laptop with a real keyboard meets my needs well enough most of the time. With ABP, Ghostery, Better Privacy, and of course, NoScript bandwidth and hardware requirements are dramatically reduced!
There's even Linux drivers for legacy hardware that Windows will no longer support... but the old abandonware plays nice with WINE. ;-)
FWIW, I first misread: "Windows 10 is best suited to its traditional PC homebase" as: "Windows 10 is best suited to its traditional PC homeless".
It's liberating not to be tied to advertising, particular vendors, and most especially... the CLOUD. :-P
In that case law enforcement might request the assistance of nearby radio amateurs for a "fox hunt" if the FCC team isn't readily available. Even my Step-Grandfather (WA6SDD) would have been willing to participate.
Receivers are cheap, frequencies are well known, antennas are fairly simple to build, and the drone's range is limited; (though rarely transmitting). It also gives "Neighbourhood Watch" a whole new reason to keep their eyes open!
