Why FPGA engineers get paid more? FPGA engineers are rare. Not because it’s hard… But because most people quit too early. You need to understand: •digital logic •timing •hardware •debugging without printf

@TheWesternOb @LearnToToad We've had a pretty good discussion in the replies. Sometimes you have to post not for the benefit of the OP, but for the benefit of those watching.

Yup. Lenses are expensive. Specialised lenses like this one (Wide angle zoom) are really expensive. I never had the luxury of owning a lens that cost more than $200, though. My dad had a couple nice ones I could borrow. I don't think he ever paid even $1000 for a lens, though. Later in life I worked in TV production for a while. Those crazy sports lenses can easily get well into five digits.

@analyst_404 @AlbatroxRS @LearnToToad "Lower noise" while the image sensor is being bombarded by cosmic rays. I've heard that astronauts, when outside the Van Allen Belt, will see flashes in their vision with their eyes closed.

@analyst_404 @LearnToToad I looked it up because I was curious. One of the engines on this launch was used on 15 Shuttle missions between 1998 and 2011. But, every engine on this launch had at least one component from the first shuttle launch in 1981.

My camera knowledge pretty much stops at the end of the film era, but... I would say yes. F stops indicate the size of hole the light has to pass through. Bigger holes are lower F numbers and they let more light through. But, smaller holes focus better. If you ever made a pinhole camera, you know you don't even have to focus it. If the hole is tiny, everything is in focus. Because the corners of the film frame (or the sensor) are slightly farther from the lens than the centre, it would make sense that a smaller aperture would keep the corners in better focus. This will be more noticeable when using cheap lenses. Good lenses will do things to compensate for this. I have no personal knowledge of why the photographer of this image used F4 instead of F2.8. Just a lot of camera nerdery here. 😜

@BowTiedDetektiv I know, right? I haven't really done any "real" photography since the film days. The fastest film I ever used was 3200.

That is wildly high ISO, but probably necessary or close to necessary for that sort of shot if the sun isn't where it would ideally need to be. Anything over 1600 ISO, and the image on my old Rebel T3 gets noise.😂

@LearnToToad ISO 51200, F4, 1/4 second exposure. Try those same settings at night on the earth and compare.

Oh, I'm not even offended by the nerd accusation. I proudly wear that for some subjects. I just didn't realise ISO/Aperture/Shutter Speed was specialised knowledge. Maybe it's just an age thing... In high school photography class we were required to log those settings for each photo we took. Digital guys today have it so easy with them being logged automatically in the metadata of the image itself.

@ScottCircuitguy @kybaskerville @LearnToToad Nothing about what you said is standard to anyone who doesn’t dabble in photography or beyond with that said it didn’t deserve for you to have to be called a nerd either

@kybaskerville @LearnToToad I didn't realise standard camera knowledge was "nerd" but those are appropriate settings for taking pictures of things in extremely low light.

@carl_xtra @VladTheInflator Exactly. Vydia filed a false claim. The only way this stops is if it becomes unprofitable to do it. There need to be consequences for Vydia.

@VladTheInflator Vydia withdrew the claims after backlash, but we have a serious problem with small private individuals being steamrolled by corporates moving on them and zero support from youtube gatekeeper and paymasters. It's truly disgusting

@wedtm @willreil @_Stocko_ Those help prevent the spread of the fire. But, be aware, they won't contain the highly toxic smoke if a battery goes up. Keep an eye on it while charging. If it puffs up, get rid of it. If it actually catches fire, get it outside immediately.

@willreil @_Stocko_ Make sure to charge in a lipo-rated firebag. Charging is where things can get spicy.

Those aren't for the Ruger 10/22. Because Ruger came out with a "Pistol" version of the 10/22, the RCMP determined that any >10 round mag that fits the 10/22 is prohib. The Butler Creek mag for a 10/22 was extremely popular up until then. It's only an RCMP interpretation. You could probably win in court if you were ever charged with just that. But, it would cost you.
