[1901.01161] Page Cache Attacks
This is kinda bad, since it leverages software caches and can be hardware agnostic, allowing write once malware that works well all over (javascript?)

Basically stripping lignin from trees to make an aligned fiber channel nannocellulose nanowood material, with anisotropic insulation properties. This spinout is marketing the stuff. Weird uses include blackening a top surface of an aligned block and floating it on a water surface, as a concentrated solar power receiver to make steam by capillary action through the aligned fibers.

Interesting semi-ephemeral p2p file sharing service. Similar to torrenting, in that you "seed" by keeping the browser tab open, and share files via a link. If everyone drops out, the sharing dies. If you stop,, but someone else keeps going, it stays alive. Uses javascript and webRTC's data channel for data hauling.

SonicNotify: Creating media in presence
Using embedded ultrasonic coded data to transmit information to smartphones, this is the audio equivalent to the QRcode. May have potential a digital watermark on live event music/audio streams. The advertising possibilities are almost endless, since any advertising URL's are automatically embedded (provided your particular audio codec which you use for recording doesn't strip ultrasonics out).

The XLR8r Flash Based Storage Array, 250,000 IOPS | WhipTail
$50K for a 1.5TB with monster random IO throughput. Has the strange property of writes being faster than reads (usually it's the opposite for flash memory storage). RAID 5 with hot spare, also uses dedup and compression to get above the nameplate storage capacity. If I didn't know better, I could almost swear they were using an all flash ZFS setup. While it could be used as a cache/high level storage tier, these guys are saying the cost/performance levels are getting to the point that it's hard to justify hard disk arrays anymore.

The Next Wave of Botnets Could Descend from the Skies - Technology Review
Oh this is EVIL, which is why I love this. Wanna be a contract UAV driver for shadowy eastern european mafia groups, right out some Gibson novel? The added trick is the tradeoff between transit/loiter time while in VTOL mode, and long duration ops during a perching fixed/landed mode.

Overview | Nexsan E60 | By Name | Products | Nexsan
Nice high density storage hardware, but a pity about the setup. RAID6 isn't going to save you from bitrot, and it only gets worse as the disk size goes up since spinning hard disk sustained access speeds have topped out around 125MB/sec, but disk sizes are going over 2TB now so restriping an array is an exercise in patience. AutoMAID is interesting, but that's really only applicable when using certain storage access styles and filesystems. Also note that it requires a 1.2m (48 inches!) depth rack (most racks are 32-36 inches!). Too bad I can't stuff Nexenta into this directly, though I suppose stringing it up via 10Gbit iSCSI to a Nexenta head wouldn't be too bad...
