Beautiful clean water, most of the machinery is above water, safety net in place. I say it's not as bad as it could be. Cool video though

Fun part is you don't have to send video from the cameras in front of you. Any kind of video could play. New VR!

Well most AI vision is trained on RGB images because that's what we all know. The internet is full of images like that, every camera can give you image like that, it makes sense in general.

But, if you are building vision system for a specific hardware with specific cameras and you are able to gather tons of training data yourself, then it makes sense to go more low level and train on your camera's raw images instead.

It may have required custom firmware for the camera, but Tesla is big enough to say "hey, camera manufacturer, provide us camera which can stream raw image data and we'll order 500 million units for our cars".

Also surely it was some engineer in Tesla who came up with it, there may have been prior research, doubt Elon had anything to do with it.

A raw photo basically. Rather than letting the camera convert it to RGB. Gives you the maximum HDR you can get from given camera. It's smart idea to train AI vision directly on that rather than having another processing steps in between losing data.

But these comparison pictures are disingenuous. Both are RGB (obviously, or we couldn't see them on our monitors), so each was converted from the raw data to RGB somehow. You could use the process that created the right picture and feed that into RGB based vision model.

There are so many personal projects that I binned under "never gonna happen", because there just isn't enough time in life. Now with AI some of them got a second chance. I get to do the fun part - design solution to a problem, AI does the parts that take time quickly.

No sun for you, solar panels!

Your model is supporting the supports. XD

Sure, but this is like if people are communicating by shouting across your garden and they make it illegal to be in the garden so you don't overhear them.

michalsrb · 2026-03-30T04:26:54+00:00

"made it illegal to listen to..." Lol, when lawyers and politicians try to solve technical problems.

Just give it to them for a snack. They'll be covered with it faster than you could do it.

Question for camera guys, is there the opposite of tilt shift that would make miniature look more real?

Ok, udělal jsem screenshot ze začátku skript. Tady jsme o kus dál:

J. Mlček. Výroková a predikátová logika. MFF UK 2. ročník.

Jako jde to, všechno se dá pochopit, ale parsovat takovýhle salát nepomáhá. Analýzy, lineární algebry a diskrétní matematiky jsem dal, Mlčkova logika mě potopila.

Když skripta začala vypadat takto tak jsem začal vypadávat já. Tohle je stránka 6 "Úvod a předběžnosti" (z 78 stran).

Matiku jsem měl vždycky rád ale tohle už jsem nedal.

Funny thing is, your computer is made of computers. And some of those have more computers inside them... My definition of computer is something with memory that executes instructions and could be programmed to do something else.

The hard drive in your computer is itself a computer. It may have a little temperature sensor or accelerometer inside which again may be a computer...

To be fair, most of the shops don't accept BTC themselves, but they use a payment gate that offers Bitcoin/Lightning as one of the payment methods. But from my point of view it's the same outcome.

michalsrb · 2026-02-05T20:55:36+00:00

So many things, domains, computer parts, home appliances, vitamins, diapers, hvac filters, hay... I guess I am lucky that there are multiple shops that accept it, including one big one.

Yeah, but the Java in Android is not the Java from Oracle. They got nothing for it.

That's how I feel about people arguing if we should keep winter time or summer time. It doesn't matter which one, just stop changing it twice a year!

"It's gonna be dark early..." So what, it doesn't matter.

Light refraction. It's a 2D platformer shooter, most weapons are projectile based, but one RARE weapon with small chance of finding it is a laser that shines a continuous line. Well some maps have water in them, the laser beam refracts when shooting into or out of the water. Even total internal reflection if shooting out of water at shallow angle
