Pretty sure 10,000db is "destroy the observable universe" power levels so.....somehow worse than nukes?

That's a 10^1000 multiplier. It doesn't even matter what unit you use really...

This guy is really amazing. He did an awesome youtube video series on writing a render engine from scratch. I used his tutorials extensively for learning vulkan.

I think it depends on context. There are a lot of sim games where the environment is very controlled and forums are littered with people who can't tell whether the occasional picture is real or in-game. A forest is hard to render accurately but a plane in flight is pretty trivial

Yea, this one goes from 0 to 100 real quick. The first half is a valid-ish argument, then the second is just an exponentially growing web of conspiracy theories...

JFC we really need to turn this societal acceptance of "you don't own the hardware" around.

It's always been legal to sell parts off your car. Do not buy anything that attempts to prevent you from owning what you bought through any sort of user agreement.

Colorado has vote my mail as the default option and it works fine. If you want to vote, you register, get a ballot in the mail and return it. You can verify that it's counted by following it online and we haven't really had any issues.

If you set up the system correctly it'll work just fine.

For an owner operator, an R22 and maybe an R44 would be able to do SF to Lake Tahoe for well under $250. For a charter service you could probably get a commercial operator to do it for maybe around ~$500 and there are definitely some inefficiencies you could remove there. Lilium is on crack if they actually think $250 is going to be the all in cost for a private flight though. You don't just spin up a new air frame and 135 operation and make money at those numbers...unless you pull an Uber on steroids and open the VC floodgates...

You can throw around statistics but the reality is aircraft receive far more scrutiny. Nobody wants to sit helplessly as one of these things flies them into the side of a skyscraper or watch as one falls out of the sky onto them.

Is that fair? Maybe?

Is that reality? Yes.

This isn't like the invention of cars. We have had all manner of airplanes for over 100 years and know how they work. This is like the NYC helicopter taxi boom in the late 70s and 80s where a number of fiery and high profile crashes put an end to the industry.

If they're operating in the US (given all the pictures of US cities) then they will absolutely be flying part 121 or 135.

I absolutely guarantee this will be anything but less expensive.

You can get an R44 with better range and payload for a couple hundred thousand. This will be an electronic nightmare requiring extensive certification and maintenance efforts. Cessna can't even sell ridiculously old designs for reasonable prices due to certification overhead.

This isn't going to be certified and allowed for part 135 operations inside at least a decade. Boeing can't keep their jets from crashing due to simple trim control software, what makes anyone think the FAA is going to go along with these flights over densely populated areas?

This feels a lot like when everyone was scrambling to start helicopter taxi services which promptly crashed and burned... Helicopters were a mature and well understood technology then, but the realities of operating in urban areas under a variety of weather conditions just doesn't allow for these services to be A) safe or B) economical.

Not if they have no funding for those things...

Really they spawned a huge industry of balance-operated electric scooter...things... The branding was much more accurate than I think even they hoped as they were a segue to more cost effective solutions.

I think it's a pretty good cautionary tale for those looking to follow the Tesla model. Don't target the ultra-high end unless you have enough of a technological and legal moat to fend off the vastly simplified and cost effective competitors.

These are all moonshot projects. If someone can come up with a creative and simple ventilator that relies entirely on 3d printed and massively available electronic parts they can save a lot of lives and it appears to be entirely possible. If they don't produce anything of value, at least they tried.

Honestly I feel like D3D12's days are numbered. Tons of engines and devs are moving to Vulkan and while Vulkan has tons of tutorials and documentation, D12 has NOTHING. If you want to just go out and make a D12 game, you basically need to join up with one of the existing DirectX shops that has all the knowledge siloed within.

They do it with software licensing for sure. There are almost certainly satellites and weapons systems out there with GPL code in them but good luck proving it.

Haven't heard that definition of canard in a while...

As with most things, I'm fairly sure the truth lies somewhere in the middle and it varies industry to industry. Yea, a lot of stuff went to china, but a lot of workers were also replaced by automated systems. In a lot of cases, I'd even venture to say maybe a majority, it was both. It's not even close to factually true to say it's JUST china or JUST robots.

Also, do you mind elaborating on how that's specifically anti-worker? Either case can be construed as such depending on your position.

Sure, however this case in particular is a bit of a counter point because covid-19 isn't causing anyone to become a child predator, nor has there otherwise been a recent tidal wave of child predators that appeared out of thin air. Seems they pushed the bill off for a bit but this whole thing was introduced at an odd time.

What's the interval they've been flying at? Has any been keeping track of how often they're spotted?

I bet by changing up the sensor pixels this would be a pretty cost effective way of making a low res FLIR camera, or really any imaging band. Using a different pin hole you might even be able to image things with xrays, neutrons, or strong 100Ghz through THz radio waves.

If it's going into a secure facility it doesn't matter if it's a phone, an iwatch or a garmin, if it has a radio and/or nonvolatile memory, it's not going in.

Check the allowable voltage input ranges for each and if they have overlap just buy a big power brick (like a laptop charger), cut the ends off of each of the supplied wall warts and solder+shrinkwrap them all together into a nice neat harness. This has the added benefit of saving a tiny bit of power assuming you get a decent main supply.

Tip: thread the shrinkwrap first before soldering. This will save you much swearing.

This kind of illustrates an important point that I think a lot of people don't realize. Strength isn't just muscle mass but also neurological conditioning. You're not just stimulating your muscles to get bigger when you work out but also refining the "programming" used to control them. In some cases, possibly like yours, this effect can dominate everything else. This is also separate from the application technique as well, such as in the cases of body builders losing to much smaller pro arm-wrestlers.

A perfect example, though it seems some here are somewhat butthurt :)

Maybe? PIREPS are not as useless as the article makes them out and systems for in cockpit weather/PIREPS and wind conditions have become much more commonplace in that time period.

I have no idea what they're referring to in terms of app or model, but Foreflight (most common EFB app on the market at the moment) has had this feature for maybe a year and is IPad only... So is this just a huge Delta ad there they're basically saying "yay, we use Foreflight"?

The exact same thing is true of any certified piston engine but on a shorter time table. Piston engine need to be removed and overhauled at the factory every 2000 hours and if a prop blade grazes the ground or hits a bush it needs to be removed, fully disassembled and have a die penetration test done at a minimum.

Also, a bush plane is, by definition, any logistics aircraft that doesn't need a runway which those very much fall into.

Carbon:

One of the most popular high performance light bush planes at the moment: https://en.wikipedia.org/wiki/CubCrafters_Carbon_Cub_EX

Turbines:

The money makers: https://en.wikipedia.org/wiki/De_Havilland_Canada_DHC-3_Otte... (plus it's twin cousin)

https://en.wikipedia.org/wiki/Sherpa_Aircraft_Sherpa

So these aren't bush planes?

Edit: further, there's nothing inherent to carbon or turbines that make them unsuitable for the backcountry. Turbines are generally more reliable and have fewer moving parts. There's nothing on them that you can't fix with bailing wire that you can on a piston engine. The Wilga is overwhelmingly aluminum monocoque but if you need to fix the cowling (the main carbon part) some speed tape will do as it's not really load bearing. The cessna I took my checkride in was probably missing half it's cowling bolts :/

If you watch the videos he adds some fuel capacity. The particular engine he's using isn't horrible on fuel consumption, particularly at altitude, though definitely worse than the original IO-540
