X-47B First Arrested Landing

kulpims says...

in short - yes. though the X-47B is unmanned, it is not a drone. instead, it’s an autonomous aerial vehicle, which means that it flies missions according to pre-programmed instructions rather than being under constant control by a ground-based pilot. this first-ever arrested landing was the highlight of three months of shore-based carrier testing, which included precision approaches, touch-and-go landings, and precision landings

Was it landing autonomously?

Everything You Need To Know About Digital Audio Signals

charliem says...

Great video, but id like to see him expand this into digital modulation, ala QPSK / QAM, and how we use it to deliver data streams of whatever the hell we want.

He didnt focus enough on fundemental frequency noise products either, carrier tripple beat / second+ order distortions. Pretty important because a single band can cause noise in heaps of places across the spectrum.

....I work in telecoms, this audio video seems like fundementals to me

Apple Maps on a Boeing 737

mxxcon says...

I think this is fake. Such smooth tracking happens only when there's GPS signal. All cellphones use "AGPS" chips, aka assisted GPS. AGPS requires connectivity to real cell towers to be able to talk to carrier's agps servers. wifi does not work with agps. IF this was taken from a flying plane, you wouldn't see "Verizon" cell connection.

Things Big Telecom Says

CreamK says...

2 years in Finland too and no choices, every carrier has it and they are priced almost exactly the same.. Just like a bunch of guys agreeing something in the backroom and miraculously announcing their campaign in sync.. Personally, i buy the cheapest phones there is and have my 12 year old prepaid still going strong. I've estimated that i've saved over 2000€ in the last ten years and that's comparing to the cheapest contract available (around 20€ is the minimum contract price.) Of course that means that i'm the only one in my class that doesn't have a touchscreen as you can't get those without contracts on a students "salary"...

StarCraft II: Heart of the Swarm Opening Cinematic

ChaosEngine says...

@rychan, so the CGI cinematic is not representative of actual gameplay? Well, that's a first!

Can you imagine trying to play starcraft if units were to scale?
From that video, an ultralisk is about the size of an aircraft carrier and a battle cruiser seems to be like a decent sized city. It'd be impossible to control.

Study Dispels Concealed Carry Firearm Fantasies

SDGundamX says...

Wow, I see so many viewing fails here.

1) Yes, some of these people are gun novices. But these people got more training in gun-handling and marksmanship than is required by most states in the U.S. and they STILL failed to stop the shooter.

2) The whole point of the video is that it takes hundreds of hours of training under stress (like in this scenario) in order for people to overcome their natural instincts and avoid a) freezing up or b) accidentally shooting themselves or another innocent in the confusion.

3) How many gun carriers (barring ex-military or police) have had the kind of training mentioned in Point #2? Of those that have, how many continue to put in the training hours necessary to not lose the skill?

It's all great spouting hypotheticals about how a CCW would have saved the day at Sandy Hook, but this video shows that's a patently false statement. What might have resulted in less casualties would have been a CCW in the hands of a highly disciplined individual with combat firearms training experience. How many gun carrying Americans do you know who fit that description?

And even if such a person HAD been in the school on that day, with the shooter wearing a bullet-proof vest and utilizing a semi-automatic rifle, there's no guarantee the outcome would have been any different.

More guns in the hands of undertrained Americans is not the answer. Modifying the social system so that identifying and dealing with mentally unstable individuals before they go on shooting rampages is a priority, though, would be a step in the right direction.

Given the choice of having a gun and not having a gun, I'll take the gun. If this video with dubious intent and setups represents some kind of "typical" or average concealed carrier, then the promoters and producers of this propaganda can suck me dry and call me Dusty.

Landing on an aircraft carrier - MiG-29K

AeroMechanical says...

>> ^messenger:

Anybody know why he makes three passes, and what kind of force he suffers while he's stopping?


Can't explain the three passes. It does look like some kind of test flight though, so presumably it's to do with giving the pilot a feel for it, or possibly data collection.

I was interested in the forces as well, and it's typically about 4 to 5 Gs for a carrier landing. Incidentally, that's about the same as a grand prix racing car experiences under braking.
