Ducted Fan Thrust Vectoring Drone

newtboy says...

How about a quad thrust vectoring drone that can split to become 2, 3, or 4 on the fly?

fun test of technology but I wonder what use this would solve better than a quad copter (or more) regarding stability in high winds and carrying load. maybe going into really tight spaces?

Denver cops refuse mandatory Covid vaccinations

newtboy says...

Just as your right to swing your fist ends firmly at my nose, your right to be an idiotic anti science virus incubator and virulent disease vector ends firmly at your property line.

Isn’t it hilarious that right wingers want to use personal sovereignty, control and authority over your own body, as a shield from responsibility for their dangerous, deadly actions, but absolutely refuse it’s existence when it comes to women having authority over their own bodies, ie abortion/birth control.

The Infinadeck Omnidirectional Treadmill - Smarter Every Day

MilkmanDan says...

Very cool.

I sure would have thought that it would be a platform with hundreds of partially inset mouse/trackballs, rather than treadmills on axes 90 degrees apart. I mean ... sure, any 2D vector can be split into a sum of two orthogonal components. But with redundant inset trackballs you could get stuff like spot pivots that are much finer scale than the scale of the 2-3 inch wide secondary axis treads...

On the other hand, these guys actually have a working prototype, so they clearly thought things through and decided that the orthogonal treadmill solution was better. Rubber meats road trumps off-the-cuff theoretical any day!

Vox: How faster computers gave us Meltdown and Spectre

ChaosEngine says...

Just for a little context... so far spectre and meltdown are proof of concept only. No-one has actually found any evidence of a real breach. Still pretty scary though.

That said, most people are probably still more at risk of standard human vector attacks than either of these.

So standard security advice applies. Make your passwords long.
"ThisIsMyReallyLongPasswordThatNooneWillGuess" is far better than "p4$$W0rd". Use a password manager so that each site you visit has a different, unique (and long) password.

And patch your devices.

Tesla Predicts a 2 Car Crash Ahead of Driver

harlequinn says...

It has forward mounted radar, camera, and ultrasound. The radar will be able to distinguish an objects size, position and vector with great accuracy and precision.

This says a little about it:

artician said:

The only way I could see it working as described is if the Tesla really has that good of object-detection onboard, was already tracking all objects, and was just that accurate in determining the speed of the impacted SUV and the rate of decreasing distance between it and the car that hit it.
Even if that were the case, I suspect the sensors on these cars get exponentially fidgety at longer distances and with more extreme angles (like measuring changing distance between two 'overlapping' objects directly ahead), it's really unlikely it was predicting the collision.
All that to say: Yeah, I agree. You're most probably right.

Could we, should we annihilate Zika mosquitoes?

newtboy says...

Whenever there's a mosquito vectored disease, people talk about eradicating mosquitos, but never consider their role in the food chain, and it is not a small role.
They also never consider the effects of the eradication methods, which are often poison sprayed into the air or onto ponds. Decades ago, a 12 year old boy designed and made a device for eradicating mosquitos in water using sound waves for a science project, and it worked. He tuned his device to resonate at the same frequency as the gas bladder in mosquito larva, popping it and killing the mosquitos without effecting anything else, and leaving no residue. For some reason, I never hear about that method being used, but instead often see people dosing small ponds with poison, oil, or bacteria, all of which harm other organisms.
Targeting single strains of mosquito with genetics may be a good way to deal with disease issues, but will certainly also have unexpected unpredictable consequences. I hope they remember the fiasco caused by creating killer bees and study the issue from all sides thoroughly before releasing them into the wild.

brutally honest interview with ex baltimore cop

artician says...

I've had this conversation, face to face, with at least 3 cops who I knew personally outside of their profession. It's these experiences that make my head nearly explode every time people say something to the contrary when it relates to what takes place in these institutions around the US.

So here it is, assholes. What kind of excuses are people are going to come up with to gloss over this particular vector of truth?

Google Translate vs. “La Bamba”

AeroMechanical says...

Um, that is game changing if it is real and actually performs that well, which is why I don't buy it. I suppose it is just a combination of OCR and the Google translate engine with some fancy font and vector graphic effects, but in my experience those things are far from perfect on their own let alone in combination.

Still, damn. I would not be surprised at all if it sort of worked okay some of the time, which means in ten years it will work pretty damn well most all of the time. That will be tremendously useful. Well, not for me, I'm an American. It's everybody else's job to adjust their language for my convenience.

Laser Etched Art

robbersdog49 says...

It's all vector. The first part is lower power, so it's cutting through to a different layer to the second part, hence the different colours. That's why the flame is so much larger for the second part.

Another interesting part for me was the sound. There must be some great patterns that would sound incredible as they were etched.

SwimWithSharks said:

I wonder how it gets the different colors (when it switches to vector mode it seems the vectors are a lot more 'golden')
