A bird detection system such as this (less so species detection and more so avian detection) would be very useful at airports where bird strikes are quite common, and where humans are regularly used to sight for birds near/around runway approaches.

I’m surprised to see they're not marketing towards the aviation (no pun intended) industry too.

Looks like a clone of Joe’s work. Sensors, capability, and even board layout are quite similar.

Surprised there’s no mention of Joe and his “AVA” on the git.

Rather than praising some of these systems and lambasting others, CR should reach out to manufacturers documenting what their testing results were, and how to improve systems. We have CVE reporting, why not something similar for vehicle automation testing?

It’s quite disappointing to see [unbiased] testers promoting some systems over others, rather than trying to up the safety/capability level across the board.

I just want to know how they installed the new nvidia cuda drivers without borking their Ubuntu/tf install.

“Applicant babysat for a colleague of the former director of undergraduate admissions”

I understand how donations or children of prominent alumni got around admissions...but babysitting can get someone entry over others? That seems like a bit of a stretch.

Didn’t know about the trickle charging, neat!

Problem with attaching a load is that if you want to build a standalone unit with the nest, you’ll need some type of inverter when powered off DC, or perhaps a simple sine wave generator? I’m more of a digital, DC power guy.

I attempted something similar, at least on the nest side of things. I quickly realized the nest wouldn’t recognize any attached equipment unless connected to a 24vac line. I always wondered how the nest derived DC power to charge its internal battery when a common line was not used. Maybe I’ll research this some more and try again.

‘"But in fact, it's a sensor defect," he said. "In future processing when we further optimize this, this will be cleaned up and interpolated from nearby pixels. But for the moment, it's still clearly visible."’

New Shepard is a suborbital rocket. It reaches apogee (velocity drops to zero), and drops back to land propulsively.

It’s possible it experiences zero-G for more than just a few milliseconds at its apogee. Hence the 0mph velocity.

Upvoted for the Saab

As did I. Up until now, I had watched maybe two videos about beekeeping in the past 6 years.

I wonder if we’re all are “binned” into some YouTube nerd classification.

I took this class in person during this past IAP.

It’s an info packed 3 days, but certainly worth it. Would recommend to anyone who’s interested in learning about flying or getting their PPL.

In no way am I arguing Apple is right here, but could this have anything to do with a possible shortage in RAM due to supplychain/COVID-19?

Better title would have been: ‘How was research ever presented in a clean, pleasantly formatted document before LaTeX?’

I would think by far it’s for crew safety.

Recovery due to an in-flight abort would be difficult in rough seas and weather if they had to be plucked out of the Atlantic.

The aerostructure of the falcon 9 can only withstand so much side loading due to aerodynamic forces and wind before exceeding the operational limits of the rocket (body to keep it all from breaking apart, and the engines working hard to keep them on the correct trajectory).

Here’s some information on the Space Shuttle Weather Launch Commit Criteria. There are probably some added bits for the water recovery incase of an abort with Crew Dragon. https://www.nasa.gov/centers/kennedy/pdf/531435main_weather-...

Edit: and for the falcon 9 (non crew) https://www.nasa.gov/pdf/649911main_051612_falcon9_weather_c...

The space suits, UI, design of it all feels exactly what I’ve though the future of space technology would be. Maybe not all the way there yet, but a great leap from hundreds of manual switches and raw aluminum of the shuttle era.

The Unity engine is the best thing to ever happen to aerospace UIs. Makes this feel like the actual future (I think) we all imagine.

Yep. It’s already being done by oculus or one of those VR startups.

Plumbers and electricians don’t go to school for multiple years to learn a trade, they apprentice - learning on the job, until they get to the point where they propel themselves forward.

I work at a company doing something very similar, owned by an aerospace giant as well.

We are led to believe that safety is the most important aspect of any part of our work. At least that’s what we’re told at group meetings and company-wide meetings. But when push comes to shove and the (arbitrary) schedule demand a test, hacky code is produced, checks fall off the list, and errors do happen.

Progress seems to be more important than safety. We are instructed to show some sort of significant return on investment within 6-12 months for the funding we’ve received. It’s pretty sad.

Telling mangers that we need to take it low and slow at first makes them angry and ignore the engineers who do the good work in exchange for engineers who do it fast.

Huh, I thought Autodesk only build software...this is cool! I'll certainly send a message.

I read this book a couple years ago, it’s great. In fact, I picked up the book 2nd hand with a note from the author inscribed on a cover page. Neat.

This book is especially interesting to anyone building systems where humans are required to interface with a computer on a “mission-critical” level.

It goes in-depth about the new type of electrical component-integrated circuits used in the guidance system. And more about other aspects of the navigation systems used on Apollo.

I recommend.

I work in Kendall sq and have wanted to ride my bike into Cambridge the past 5 years.

I’m (almost) deathly afraid to ride make the short 4 mile trek across the river for exactly this reason. I lament every day I get on the T to slog for 45 minutes on a decrepit, slow, and usually broken train system. I arrive to work bothered by my commute almost every day.

For Boston/Cambridge being such a bio and tech hub, it’s entire transit system (roads, busses, trains, biking) is amongst the worst I know of in the US.

Sad.

I worked as an undergraduate in a academic research lab trying to develop this exact stuff. I would also hazard a guess that we were funded by the same ARPA grant as niron was.

It was a cool concept and got me interested into materials science. Unfortunately the post doc didn’t seem to care too much and the work didn’t go anywhere.

Neat stuff none the less.

Neat.

Would have been nice to add some sort of discriptor indicating what type of dataset it is. For example, I personally have no clue off the top of my head what the “MURA” dataset is.

Edit: I now see there is a little icon on the left of all lines. Bit ambiguous, but it sorta gets the point across.

I met him at a talk about a year ago, I would agree he is somewhat egotistical, but he didn’t come off as arrogant - which was interesting.
