Short and sweet, kind of like how my holiday vacation has felt (how did I manage to get very little of what I wanted to do, done?)

Aerospace

AERO1Boeing’s refueling drone.  Carrier launched and recovered.  Given that all it needs to do is fly straight and level, this is actually a proper job for a drone.

AERO2 – NASA’s upcoming missions around the solar system.

AERO3 – Musk is usually way too optimistic with his initial timelines, but he has a good track record of eventually coming through with a product.

AERO4 – China flies it’s own goose.

Architecture

ARCH1 – That’s one way to save on the cost of fasteners.

ARCH2 – This is how you design for windstorms.

Bio/Medical

BIO1 – Is the RNA genesis theory about to be supplanted?

BIO2 – FDA is going to finally start cracking down on homeopathic cures.  Not all of them, just the ones whose claimsare dangerous, bu it’s a start.

BIO3 – The one and done flu vaccine, through DNA.

BIO4 – Bacteria be all, like, chill and all.

BIO5 – Another reason to eat your salad.

Computing

COMP1 – DARPA wants unhackable computers.  Well, from the hardware side, anyway.

COMP2 – Caliburger not only is doing away with order takers, it’s making sure the order kiosks know a repeat customer when it sees one.

Energy

ENRG1Floating Solar Hydrogen Platforms have a novel electrode design that allows for easy gas separation.

ENRG2 – I wonder if this would be useful for ENRG1?

Materials

MAT1Graphene Body Armor.  Just in case it isn’t obvious, the body armor itself would not be two molecules thick, it would be sandwiches of two graphene sheets separated by some other material, until you had enough layers to stop a bullet.  Just two sheets would never be able to do the job.

Physics

PHY1 – Mathematicians are trying to poke holes in the Navier Stokes equations.  These are the equations I use (among others) to do fluid simulations, and the work they are doing won’t invalidate the equations, but rather, try to determine if there is an actual solution possible.

Wacky, Weird, and Wonderful

WWW1 – All Eye want for Christmas.

WWW2 – The first man to fly in space without a rocket has passed away.  Fair Winds and Following Seas, Spaceman.

    • Calitron is rampaging through downtown L.A. destroying all it sees, and occasionally stopping to scream things like, “Why don’t you want avocado mayo on your chicken sandwich, James?! Everyone in California loves Avocado! DIE!”, at fleeing pedestrians, before vaporizing them with jets of boiling fry oil.

How can an insurance company justify not gathering that kind of information? And if we can sue cigarette companies for our cancer, why can’t we sue fast food chains for our weight gain?

          We ourselves struggle with concepts of fairness and justice, yet we are offloading more and more human management tasks to algorithms and machine learning.

          Who gets priority for a job, an apartment, a space in a school; Who is at risk for crime, poor health, child abuse, bad credit; Who gets a promotion or dismissal; Which community should get an upgrade to its infrastructure and associated jobs.

          We can’t possibly tell the algorithm to produce a just outcome because we ourselves don’t even know what it looks like.

            Someone brought up the AlphaZero game-playing software (self-teaches all of Go, chess, and shogi playing against itself) the other day. It’s better than human play has been described as “chess from another dimension” and “Go from the future” by some of the best human players because the program wins doing things that make no sense to people.

            One of the things Stross describes are Facebook experiments with identifying people even though they don’t have a Facebook account from indirect things like picture tags, textual references, etc. Should such a person get a Facebook account, the software will already know considerable about them.

            Goal-seeking software and big data are a scary combination.

            • I had a long discussion with a colleague recently about the role of technology in the classroom. My position was that we can’t really talk about “technology” without defining what “technology” is. Right now, when we’re talking about technology with younger children, we really mean screens and little else. So if we want to talk about screens, let’s talk about screens. But in reality, especially for young children, “technology” is damn near any tool in existence, since almost all of them are new or novel. At which point I argue that technology should be used for two primary purposes: to make the impossible possible or to make the already possible better, easier, more effective, more efficient.

              Then everyone wants to talk about screens and apps again.

        • I took it as sarcasm and was not offended.

          Anyone who looks at military tech has at least thought about the question, “What kinds of anti-ship tech could keep carriers at a distance outside the round-trip range of their planes?” Certainly the US Navy research program thinks about it: aerial refueling, laser weapons, and rail guns (as well as the greatly augmented on-board electrical generating capacity to make all those things feasible) are all responses to that kind of threat.

        • Sorry, forgot the sarcasm tag.

          As I’ve mentioned before, in the Navy, carriers are referred to as LSTs, Long Slow Targets. Their primary weapon(s) are the aircraft they launch and recover, but their defensive ability largely rests upon the Aegis systems in the cruisers and destroyers that act as their screening elements. So it isn’t the carrier itself that is the actual weapon system, but the fleet that is centered on the carrier.

          Kolohe might know better than I, but I remember rumors that both Russia and China have been developing cruise missiles that are fast and smart enough to work their way through an Aegis screen and hit a carrier (something the Navy is not happy to admit to, hence my sarcasm), which would give the Navy a strong incentive to be able to extend the range of their air wing without having to rely on the USAF or Navy tankers that are limited to land based airfields (tankers that are notoriously un-stealthy and slow and easy pickings for a hostile air force).

          • Carriers died the first time a drone fired on a target. They just don’t know it yet.

            Hell, the modern Navy is a dead beast walking, as is the Air Force.

            Their combat roles can be better filled by swarms of much cheaper, semi-autonomous drones operating under the control of coordinators hundreds or thousands of miles away. The Navy, commanded by “captains” sitting in a chair on dry land, or the Air Force flown by “pilots” in front of monitors in Nevada.

              • The current big roadblocks I can see are AI limits (because, you know, jamming is a thing) and getting rid of the need for GPS.

                In a real stand-up fight with someone roughly on our level, communication will often be spotty to non-existent, and the GPS network is going to be hammered or absolutely gone.

                But even now, other than the initial grab for air superiority (ie, when all the jamming and GPS busting will be at it’s peak), you could replace the rest of the AF with drones.

                Just have them loitering around combat areas, beaming back intel and ready to be directed to hot spots as needed.

                As for the Navy — drone carriers alone would be a pretty big win. More projected power, smaller and cheaper ship. Life support ain’t cheap. Toilets and food and clean water and bunks all that other messy crap.

                  • EMP hardening is a thing, but it adds weight. Modern military aircraft can afford to carry that weight, but drones might not be able to afford it as easily. Of course, nobody has a directed energy EMP weapon yet (that we know of, I am sure DARPA & UNR have that on their Christmas list), so the only way to do it is via an omnidirectional pulse, which will fry anything not hardened.

                    So, tricky to use, so not something most folks defend against (military does because nuclear weapons).

                  Back in the second half of the 1970s, my wife ate lunch regularly with people who wrote cruise missile software, and who would answer pretty much any question the pretty young woman asked. Even then, they did some amazing things with inertial navigation and terrain recognition radar.

                  My favorite story she had from that time was one guy’s description of a recent test: “After launch, the missile flew down the valley properly, made its sharp left turn at the proper place, flew up and over the first mountain, flew up and over the second mountain, then flew smack into the side of the third mountain. Debugging this one’s going to be tough, given that all that’s left are parts scattered over several acres.”

              • It seems like that depends heavily on how simple the missions are. If they’re simple like “destroy this thing that was last seen at XYZ location and we don’t care if you come back or what other stuff you damage in vicinity,” that’s pretty tough to stop.

                “Oops, I’m scrambled. Therefore, kamikaze the scrambling source”. After all, signal strength would grow if you’re heading the right direction, so it’s not hard to find.

                  • Except, you know, drones are cheap. (Relatively).

                    You jam a pilot the same way, only you’re limited in the number of pilots and very expensive aircraft they’re in.

                    There’s always the evolving nature of the battlefield, but the thing about drones is — without all that massive amounts of equipment for keeping the squishy human alive, and the fact that performance is also limited to keeping the squishy human conscious, and of course being stuck reacting at slow squishy human speeds…

                    You get better performance all across the board. For a lot less.

                    So much of a fighter, or a bomber, or even a navy ship is based around the squishy human and their squishy human needs.

                    What if you don’t need ejector seats, or a cockpit, or all those instrument displays, or reserve oxygen? What if you’re not limited to maneuvers that humans can stay conscious for, when your design doesn’t require “fitting a human and all his crap” into the machine?

                    When you can replace the bulk of that with more dakka? Or make the vehicle smaller, more agile? Cheaper? Stuff in more fuel, more counter-measures, or just build a crap ton of smaller ones?

                        Seems easily swarmed, or frustrated by things like rotation or reflective chaff.

                        • Depends on what you are trying to do. If you are trying to burn a missile out of the sky that is on terminal guidance, yeah, you’ll need a second or so of intense focused beam.

                          But if you are just trying to permanently disable a drone, your attack can be very different.

                          I mean, make no mistake, drones are a game changer, but we are a creative bunch of monkeys, we’ll figure out a counter.

                              When it comes to the Navy, what I strongly suspect is we are seeing the final days of the aircraft carrier as the core of the fleet. What we’ll see coming is SSNs*, CVNs & DDGNs along with littorals all sporting drone modules and each one maintaining a small wing of drones to do bad things to other people.

                              *SSNs could surface, launch a bunch of drones from a topside bay, and submerge while leaving a small floating antenna array on the surface for drone C&C.

                                I mean imagine a submarine going into combat starting with deploying a shoal of small, fast, one-shot little buggers around it whose sole job is to kamikaze those loud, incoming torpedoes. All you need is a shaped charge on the front end.

                                You don’t even need that much speed on the things, because torpedoes will be heading right towards the sub (and thus the defensive shoal) so generating an intercept vector doesn’t have huge energy requirements….

                                Of course after that, it deploys dozens of autonomous torpedoes that flood the area, trying to come in on novel vectors…
