Anyone know of any good use cases for a 3D models or simulations at the city scale apart from eye candy, e.g. public presentations of future urban development?

I worked in this space for a while and I never found much of a use case for serious applications of 3D over say an ordinary 2D GIS. Ended up building applications using PostGIS openstreetmap etc that were a lot more effective.

SHYLY SLYLY

It doesn't seem to be saying that colorless green ideas sleep furiously. Is that what you love?

That would be called cislunar space.

David Fravor was talking about the Tic-Tac video which was over ten years before the Gimbal video in the article.

Right, this is how I understand it too. Is it not true if you took two photos of the same subject, with say a 24mmm lens and 70mm lens, and the then cropped and enlarged the image from the 24mm lens shot, you'd end up with the same image with the same perspective?

Fair enough, many are ugly, but I generally quite like the way they look. Lots of scope for different shapes and colours and textures. They can be blended in with the local geology via the choice of rocks. You can put benches or pathways on them, or soil on them and grow plants, or even grow mosses and lichens.

You can leave at will if you're not an Australian citizen or a permanent resident. If you are, then you currently need an exemption, e.g for work or business, or you're going to live in another country.

We're expecting the policy to start to be lifted when we reach 80% double vaccination rates, in around 4 to 6 weeks time.

As I understand it most meteorites, especially small ones, are cool when they hit the earth.

Nutty article suggesting Covid and other diseases came from meteorites

Yes, it can happen due to alpoecia areata which can be stress related. I had a beard hair turn white almost overnight. I am normally clean shaven but a large section of my facial hair fell out at once and almost immediately grow back white. I think it took a few days but seemed to happen overnight. Also alopecia can tend to attack just coloured hair, so if you're salt and pepper and lose all the coloured you can appear to go white overnight.

About two years ago I woke up to find 40% of my facial hair gone. It was due to alopecia areata, and I was going through a very stressful period. It mostly grew back but completely white (Funnily I'm left with a narrow black section in the moustache area, so if I don't shave I look like Hitler).

Anyway in the last month or so some coloured hair has started to come back, hopefully it continues.

I'm reminded of the joke "If Microsoft Made Cars" from the 90s.

And 25 years later here we are...

' For all of us who feel only the deepest love and affection for the way computers have enhanced our lives, read on. At a recent computer expo (COMDEX), Bill Gates reportedly compared the computer industry with the auto industry and stated, "If GM had kept up with technology like the computer industry has, we would all be driving $25.00 cars that got 1,000 miles to the gallon."

In response to Bill's comments, General Motors issued a press release stating: If GM had developed technology like Microsoft, we would all be driving cars with the following characteristics:

1. For no reason whatsoever, your car would crash twice a day.

2. Every time they repainted the lines in the road, you would have to buy a new car.

3. Occasionally your car would die on the freeway for no reason. You would have to pull to the side of the road, close all of the windows, shut off the car, restart it, and reopen the windows before you could continue.

For some reason you would simply accept this.

4. Occasionally, executing a maneuver such as a left turn would cause your car to shut down and refuse to restart, in which case you would have to reinstall the engine.

5. Macintosh would make a car that was powered by the sun, was reliable, five times as fast and twice as easy to drive - but would run on only five percent of the roads.

6. The oil, water temperature, and alternator warning lights would all be replaced by a single "This Car Has Performed An Illegal Operation" warning light.

7. The airbag system would ask "Are you sure?" before deploying.

8. Occasionally, for no reason whatsoever, your car would lock you out and refuse to let you in until you simultaneously lifted the door handle, turned the key and grabbed hold of the radio antenna.

9. Every time a new car was introduced car buyers would have to learn how to drive all over again because none of the controls would operate in the same manner as the old car.

10. You'd have to press the "Start" button to turn the engine off." '

It could well be true that 77% of people are smarter than average if intelligence is a heavily skewed distribution.

Could also be true in an unbiased datasource in a skewed distribution.

Can you elaborate on how you reach that conclusion? A taxation system than encourages more efficient use of land leads me to the opposite conclusion.

The difference is you can opt out of the crypto game, not so easy with natural resources like land.

As a counterpoint, there are examples where the introduction of species has been spectacularly successful for ecosystems.

I got an 8" Dobsonian about ten years ago at still am far from exhausting the possibilities. I got the Bintel (GSO) brand which seemed a little better, came with three eyepieces decent focusser and finder, and moon filter.

You can move the 8" Dob around with one person and fits across the back seat of a small car. You manually push it around so you learn to star hop, and learn the constellations more than you would with an electronic GOTO.

Only last year upgraded the eyepieces to Baader Morpheus. Gives good claer views of Saturn & rings, cassini division, Jupiter & great red spot, equatorial bands, Uranus, Neptune, Messier objects etc etc.

A 6" dob is a good option for planetary viewing too and arguably better than 8" in some regards (a bit smaller and more forgiving on cheap eyepieces). 8" is better for deep space objects of course.

Consider a 10" dob for deep space, but they start to get a bit large to move around.

How about an ordinary electric car with a small trailer carrying a fuel generator?

Could be countered with active noise cancellation paired with Shazam type audio track identication.

We were within about 10kms. Ethernet connection, no wifi.

During lockdown I was able to have music jams with high quality uncompressed audio at 10ms (effectively real time), using Jamulus for the audio, and Zoom for the video. Then the whole thing was live streamed to Twitch.

Check out this great 1.5 hour interview with Chuck Yeager from 1991. His comments on NASA were particularly interesting.

There are 2n symmetries for an n-sided polygon. In this case five rotations and five reflections. https://math.stackexchange.com/questions/490054/symmetries-o...

And Poland cracked Enigma in 1933, and then shared their techniques and Enigma clones with the British in 1939!

I support the idea of UBI in principle, but I think it needs to be combined with a land value tax in order to work as intended. Rents are charged at the highest the market will bear, so the UBI could just flow into the hands of landlords, and the people who it is supposed to help being no better off.

i.e., a bat phone.

What oil soluble dye did you use? I was looking for oil dyes for another project and I found them hard to find.
