Limitations of Pay Pal and how it’s side stepping them

I’ve used PayPal for several years now on my iDevices and PC’s, mostly for paying a few monthly subscriptions and moving money between bank and credit union. It also enables me to pay for my minor excesses out of my ‘monthly money’ rather than the family general account. I have bought a couple of big-ticket ‘toy’ items using the credit account and then paying back over a few months, or better saving up then using PP to buy the lusted after item over the net. I think PP is a useful service and I trust it more than I do big bank credit card services though that’s a little player vs. mongo player preference rather than real in-depth analysis.

Pay Pals weakness has been the network effect. In general the more members any network has the more useful it is. While PP is pretty widely spread these days it’s not getting bigger quickly enough and I have continued to use other methods of paying for most things.

PP has solved at least part of this growth problem by moving into the credit card world. Establishing a PayPal Master card in place of its own credit account. This enables users to pay through the immense existing credit card infrastructure but use the PP ‘back office.’

In one sense it’s a bit sad that PP had to just become another credit card. But they do provide a lot of other services and a way to manage and move your money around in the banking system.

Sikorsky S-97 First Flight

There have been several articles regarding the Sikorsky S-97 Raider, which achieved first flight this week. The Sikorsky S-97 Raider prototype takes to the air for the first time

FoxtrotAlpha’s got a good backgrounder on this aircraft, its history and future.

There were some nay sayers in quite a few comments that I hit on a couple of the articles that pooh poohed the coaxial rotor as a limited solution for high speed vertol aircraft.

I think the mistake these folks have is confusing this machine with the older coaxial rotor machines like the Kamov KA-50 below (“Russian Air Force Kamov Ka-50” by Dmitriy Pichugin)

Russian Air Force Kamov Ka-50.jpg

A quick scan of the two pictures, focusing on the rotor mast and then the blades, will show you that there are a lot of differences in the aerodynamics.

Helicopters are speed limited because the blades are moving in respect to the air passing the aircraft. On one side the advancing blade adds to the air speed and at the tip can easily move towards the supersonic where air becomes in-compressible and aerodynamics change radically (which is why the blade tips on high performance helicopter blades are swept like a fighter wing) On the retreating side the blade can quickly reach stall speed and loose lift..

Coaxial rotors have the advantage of putting more energy into the air in a smaller rotor disc. Because the length of the rotor blade has a large impact on the tip speed this reduction means that the aircraft can fly faster before hitting the above limits.  Also since one blade on each side is advancing and the other retreating lift is symmetrical even if the retreating blade looses lift, meaning the aircraft can fly faster.  And indeed the X-2 demo aircraft Sikorsky built as a tech demo before the S-97 hit something like 300 miles per hour while a conventional chopper maxes out at about 150.

The principal difference between the KA50 and S-97 is the type of blade control. The S-97 has a so called rigid blade, which does not have a flapping hinge at the rotor head. The hinge is part of the  conventional blade control system allowing the blades to flutter somewhat as the lift changes through the blades rotation (you can see in the picture of the KA50 that the blades are at various incidences to the path of flight, partly because of the turn but also because of this ‘flapping.’)  The more advanced though simpler and more rugged rigid blade system on the S97 is based on advance composites and aerodynamic control theory.

So why does it matter, why do we need faster helicopters?

Simply put speed up to a certain point is always a winner because it means that for the same cargo load you can move more material in a shorter period of time. It also means you spend less time in any particular point in space which in a military context means you’re less of a target. Fast and being able to land anywhere and hover behind cover are all very interesting to the military.

Harrier jump jets

The other fast vertical take off aircraft, the jump jets like the F35 and the Harrier or the tilt rotor V22 Osbrey are really optimized for vertical take off and landing and fast transit, the jump jets have no real hover capability and the Osprey is a big and somewhat clumsy helicopter. The S97 is much more of a blended capability and its simpler and cheaper than a jump jet or tilt rotor. Sikorsky is hoping that they can convince the DoD to forgo doing too much specmaniship and competitive development and move forward with the coaxial rotor machine for the next generation of vertical lift air mobility platforms.

Of course right now the outlook for anything new is pretty bleak and Sikorsky is probably struggling to figure out where to take the technology they have developed. A typical ‘innovators dilemma the world of modern military acquisition.

Burger bots…will their be riots and nuts and bolts in the streets?

IMG_1046.JPG
Good article at the Singularity Hub it’s obvious to me that the hamburger flippers’ days are numbered, so how will society adjust? Luddism only goes so far, the general populace will see the bitching, moaning and breaking things as what it is, the last gasps of the un imaginative and paleoProgressives unable to see it ain’t 1959 any longer.

Track Points lower price point Precision Guided Firearms

IMG_1043.JPG
So again ars Technica has a great article on Track Points latest products, $10,000 AR15 class weapons with their tracking/guidance package.

This is a remarkable technology and if I wanted to hunt it’s one I’d consider since you’re much more likely to get a clean kill.

These weapon’s make almost anyone a one shot one kill marksman, eroding a little the ‘advantage’ of a professional and increasing my concerns regarding their use in politically motivated murder.

The use of the weapon wit a remote sight also increases my concern in this area though the existing versions are heavy very expensive and near useless at short range.

However those disadvantages will rapidly dwindle, the technology is not that complex and I can see many bells and whistles I would work in over time.

In the not to distant future advanced combat forces will be using this and derived technology on all of their firearms, the battlefield will become deadlier and counter measures, operational, tactical and technical will be deployed.

Some in the political arena will want this tech banned, they may succeed in the short run. Some may demand it become mandatory, with the development of a human target recognition element and over ride…an expansion of the smart gun push.

But for now, it’s a cool use of technology by some pretty savvy guys and it’ll be fascinating to see where it goes.

Mutant Ninja Turtles 2014

teenage_mutant_ninja_turtles_ver14_xxlg-720x1013OK so Rotten Tomatoes gives it a grilling but its a fun movie and pretty well done.  I’d be lying if I say its worth full price or 3D, but cor a matinee, which is all I and my son go to, its…well…fun.    It gets the tone right, neither too campy or too serious and the characters are, uh, well what can you say about a near seven foot, bipedal rat and turtles? The characters have to have lay it on thick personalities that was the way they always have been.  The TNMT’s are fun loving reasonably serious young guys.  The bad guys are villains with goons what can you add?  Megan Fox’s character is central, and she held the movie together.   Her O’Neal is not a shrinking violet, victim or Mz KickAss, for the plot she had to be a bit pig headed and very naive, but she was well cast and played it well.

We’d certainly go and see a sequel if it’s done as well and doesn’t have much competition.

 

Guardians of the Galaxy, go and see it!

hr_Guardians_of_the_Galaxy_film posterSo Marvel’s Guardians of the Galaxy is a fun movie.  If you want a fun afternoon or night out, go a see it, you’ll laugh and be amazed.  I love Groot and Rocket Raccoon the two CGI characters shown  in their own movie poster below.

There are many who are over the top about this movie, I think because it could have been awful and isn’t.  There is something about the movie that makes me hold back from saying Fantastic, but it is very, very good. There may be other things playing in, but  the pace was too frenetic the cutting too staccato for me to fully enjoy.   Also a lot of characters seemed to intimate some link to a deeper story that we didn’t get to see. An introductory movie set in a deep universe like Marvel’s may be prone to this and my ‘author’s bump’ maybe too sensitive to these things but these ‘issues’ kept me from getting as deeply engrossed as I did in Edge of Tomorrow and some of the other Marvel films.

But its a fun movie, go and root for Groot, Rocket and their pets.

Lucy the Movie

Lucy_(2014_film)_posterLucy is a disappointing movie. That is not to say it is awful, but I could not argue with someone who said that it was awful.  For me the movie started out very well and was watchable throughout but it left me feeling like I had seen a Hollywood Horror, not the child of the Luc Besson, director of the movie The Fifth Element.   The movie feels like it was cut short.  Started out on a path like, if a bit less out there than, TFE but then got chopped short.  It as if the script was written around a very tight plot but instead of spending time fleshing out the story and the characters it was decided to just get something out the door as cheaply and quickly as possible.  I suppose that Johansson or others were not available for the time Besson needed to do a TFE like work.   Whatever it was this is a very disappointing movie, mainly because it had great potential.

The details:  the violence is what some called ‘over the top’ but unfortunately it’s what I call pseudo realistic; Lucy starts out as a believable type…and ends equally believable but without an audience leading transition ; while the Lucy UberHuman [LUH]is believable I think a more relate-able version was possible ; the LUH’s abilities are fantastical, over the top, a creepier, more understated version was  possible ; the plot is ultra simple and while the plot holes are there they don’t derail the movie ; [SPOILER ALERT] the bad guys are workmanlike if a bit too Bond-Goon-Squadish, but I really really wanted to evil surgeon from the early scenes to get terminated with prejudice ; the end is utterly anticlimactic the ‘happy’ ending wasn’t cheery and had no punch, the LUH metastasizes to another plane leaving behind the USB key fob to the universe, the confused boy toy police guy gets a text message from the beyond and the world goes on…meh.

Details of the details:

LUH’s creation: The crap about the utilization of the human brain was good as a way of thinking about human capacity but its scientific bunk, which spoiled the movie a bit for me.  The drug was TFE Beeson over the top (as was its introduction) but its derivation and supposed affect were not very convincing.  I’d have bought a material that increases intelligence by accelerating and reorganizing the brain, but requires constant new fill-ups or the user becomes a vegetable, it’s the first of a new family of bio-nanotech human enhancement drugs the Chinese mob has stolen, one vial of the stuff could infect hundreds or thousands, who would all become vegetables if they cannot get the fix… a trope matrix that could have been much more scary.

Violence:  I think that LUH had to use violence she had no time to explain.  The emotionless LUH had no compunction about using it which was funny the first time but troubling with no context.  Also the violence was too risk free, humans react to violence, modern training makes us hesitate but there are many among us who would react almost instinctively.  LUH did to some extent explain herself to the surgeon but the hole here was their reaction to her and the lack of a police response in the time it took to take out the bag etc…A couple of soliloquies or appologetic explanations to victims (even dead ones) would have helped and could even have been funny….

Emotionless: Emotions are chemical and triggered by autonomous systems, LUH could suppress them…believable.  But I lost any real human interest in the whole story when I knew she was essentially a machine with a hard stop use by date.  The appearance of the hurting, frightened, grieving old Lucy would not have been hard or out of place, her goodbye to her mother was only part of what should have been a thread through to the end.

LUH powers: Telekinesis, really? Mental control of electronics plays into my idea for LUH abilities but its just magical crap with the trope used.  With ability to control her physiology, and ultra fast processing she could have senses and reactions and strength way beyond the norm, and would have needed to eat like a horse (that was consistent in a way) she might be able to exude skin oils or pheromones with powerful effects, could heal herself fast, maybe even read minds if in contact with the target, etc, etc.  These effects and her having to think her way out of dead ends would have supported the simple story line.  The magical powers she exhibited should have been part of a movie with more complexity / depth in other areas, where those powers play are a way to keep the story moving fast….here they just truncated this already too simple movie.

Bad Guys: OK pretty good in a Bond Villain Goon Squad sort of way but still.  And what about the evil surgeon? he really needed his own poetic if gory end.

The ending:  A more effective ending would have been failure…the bad guys kill her, the bad guy’s die, maybe science guy and boy toy survive to grieve Lucy’s death.  Then maybe a hint that she did not fail but that she had made sure that the bad guys got sucked in and destroyed while the drug or whatever that created LUH will be treated like a mixture of nuclear weapon and Ebola.
