It might be nice in a server room to reduce noise (94dBA in mine at the moment), but I hate to think how it'd fare in a domestic environment - particularly with "sticky" fine dust such as cigarette smoke or oil-laden cooking fumes (my wife uses her laptop mostly in the kitchen)
Other than that.... significant mass, spinning that fast. Interesting gyroscopic effects to say the least.
Such as the Iranians are advertising using small ekranoplanes are easy to deal with, as long as Phalanx systems can point downwards.
This looks like a solution in search of a problem - and given the pointers about logs/whales from other posters - what happens if this baby hits a significant underwater obstacle at 100 knots? (I assume the navy will run that test under remote control to avoid severe injury to human operators.)
Presumably a large part of the above-water noise dampening is achieved by simply directing engine exhaust into the supercavation bubble - which enhances the effect.
I can't see this as a practical SEAL delivery boat.
As a point of interest - targetting the source machine will make you feel good but achieves very little in the overall scheme of things unless you have a very fat pipe.
Routers are much less robust. They generally can't handle a large stream of traffic directed at their own IP addresses (which is why I tend to have my routers using private address space).
Not that I advocate this mind of thing, of course. It's on par with sending "ping of bluescreen" to virus-spreading windows boxes and is naughty.
And they work. They're a useful compromise between size and cost but in the end they're an interim technology step that's useful on laptops or other "single drive only" applications. I have them in cookie-cutter Linux desktop installations - these boxes use network storage for everything except the OS - including $HOME
For all the pissing and moaning about failures: Drives fail. That's why you have backups and RAID.
Spinning drives only give advance warning about half the time. SSDs usually fail to read-only mode.
failure rates on spinning media have been increasing for the entire decade. That's what's driving manufacturrer consolidation (and always has done - makers who don't produce reliable drives get bought out by those who do)
Tb-class spinning drives have appalling failure rates. (15% in the case of my Samsung 2Tb drives, but I still keep buying 'em - they're cheap and I don't lose data), but that's why RAID was invented.... Tb class drives are cheap enough that a 12-drive raid6 aray (or Raidz3 if you use ZFS) costs less than the sas expander you'll need to drive the things.
SSD falure rates are declining
Cheap MLC SSDs aren't designed to be pounded on. - In the same way that a Geo Metro isn't going to survive long if you take it on the paris-dakar rally. Stay within the design parameters and things will be fine.
Expensive SLC SSDs are virtually indestructable. I have a Raid0 array of 5 X25Es that on average has 4Tb/day pass through it (backup spooling). 4 years on, none of those drives have skipped a beat or show any wigns of serious wear - but I've had to replace 4 (out of 12) "enterprise SATA" 250Gb spinning drives in the raid6 array that handles the database those SSDs depend on.
If you need lots of storage, don't do it on a windows box. There's a lot of pain and suffering along that path.
If your machine is swapping, then you're in trouble. Add more ram or cut down on processes. Swapspace is an emergency fallback. As soon as you hit swap you're only as fast as your hard drive - and that's firmly back in IBM XT territory, whether it's SSD or Spinning media.
The problem was the local tabloid rag (not known for being all that truthful) latched onto a couple of the photos and ran front page stories demanding the dinner ladies be sacked.
Unsurprisingly the story is now missing from their online archives, but a few people have thoughtfully mirrored the pages in question.
A council employee in Argyll and Bute has been suspended while an investigation is under way into so-called "social media spying".
It comes after communications chief Jo Smith reportedly told a conference she set up fake social media accounts to monitor what was being said about the council.
One of the local authority's biggest online critics, For Argyll, said it was a "sacking issue"
===
The employee in question was _boasting_ about what she'd done at a conference of IT managers - it's no wonder some decided to do something about it.
As a commenter on another site said,
George Orwell wrote 1984 whilst staying in Argyll, and the local theory is that the council uses that book as its operations manual.

I was hoping that the FDA had arrested one of Shane Atkinson's associates in the ongoing "Canadian Pharmacy!" fake drugs scams.
"Free market" is not "fair market" - the natural end game without government intervention is swinging monopolies and rapacious cartels.
