Yes

People here and on Reddit really think that polls are made with just a few calls and then some average/extrapolation and that’s it.

Meanwhile it’s an entire field with a lot of complex math and people with more knowledge about it than everyone in this comment section combined.

And then the classic “polls are shit, they always get it wrong”. By definition polls are correct because they just represent an objective data set. Then they translate it into a phrase that we humans can (somewhat) understand but people then take it wrongly.

They read “Poll X says candidate Y will win” when instead they should read “According to the data obtained for Poll X, candidate Y has a Z% chance of winning with a confidence level of W%”. And that isn’t wrong unless someone wants to find the mistake in the math.

Quick 100$?

This one is still quite long

I wished he made his videos closer to the 20min mark

I’ll probably still watch it, but at almost 30mins it might take me some days to start it.

And the reheat button on microwave

I’m still mad that I have a shitty microwave now

That’s exactly why I do it

The s option is very useful to split the chunks.

I basically always do a git add -p

Very useful command and it works with other git commands as well.

Everytime a colleague asks me for help with git that’s the one rule I suggest them to use.

We’re all gonna die so it’s still a very much true statement

And I agree, much more dramatic

Historically incumbent presidents always have the upper hand.

Apple makes some really stupid products that they charge ridiculous money for and their usual stuff is more expensive than it needs to be but at least their core products are of very good quality. The same cannot be said of Tesla

In a concurring opinion, Chief Justice Tom Parker cited his religious beliefs and quoted the Bible to support the stance.

“Human life cannot be wrongfully destroyed without incurring the wrath of a holy God, who views the destruction of His image as an affront to Himself,” Parker wrote. “Even before birth, all human beings bear the image of God, and their lives cannot be destroyed without effacing his glory.”

wtf

I mean… do you trust that they won’t?

They probably will as soon as they can without significant losses.

They don’t require high internet speed at all. Why do you say that? You have to keep up with the network that creates a couple MBs of data every 10mins. That’s it. You need processing power and as such electricity but none of that requires high speed internet, quite the contrary. You can get away with a mobile data in most places.

I’ve read different stories. Of towns where cheap and renewable electricity can be made but it’s financially not viable especially at the start. So Bitcoin miners were used to sell the excess energy and that made the project possible. In a way something like Bitcoin can create a global price/demand for electricity which can have its advantages like I mentioned or disadvantages like you mentioned.

The thing that everyone misses in these comparisons is that yes that’s the energy that VISA expended to make these transactions but for a crypto currency the energy use isn’t even to make the transaction. In the end each transaction is a few Bytes of data that have no difficulty getting across the world (much like this post or any comment). The energy use is so “high” because that’s is used to secure the currency. And of course that’s a much harder comparison to make but a fairer one.

How much energy does the the banking system actually use? How much energy is used to secure the US dollar for example?

You have to account for the entirety of it. That’s like saying that F1 doesn’t pollute all that much because they use bio fuel and the cars are very energy efficient, completely disregarding the fact that the majority of the pollution is in the constant global shipping of cars and gear, as well as R & D

Don’t forget the misogynistic and racist component of his comment.

You are way too defensive and triggered for the “authority” you supposedly have. And I do believe you. Also you gotta learn to chill and read. I’m not moving goal posts here, you just like to rant. Also big lol at your first paragraph in this comment. Hilarious irony there. Loved it.

Answering your comment and trying to wrap the discussion (I’m not gonna block you lol, what are you even talking about about). What I disagreed with your original argument is that doing a bridge inspector isn’t just getting some semi-pro pilot with an expensive but generic drone with a fancy camera. Snap some photos from a few meters distance and bam, job is done and you inspect one side of a small bridge in 1 flight. That’s it. It was pretty clearly laid out in my comments. To get any meaningful data you basically want/need to get as close as possible. And this usually means actually touching the object you are inspecting. You allegedly have experience in this field so I don’t need to tell you that “regular” drones (and by regular I mean not collision tolerant) don’t like to fly very close to large metallic structures. I’m sure you can guess why.

Not that it matters but yes, I have more than 5 years of experience as a Robotics Engineer working with drones. For my masters thesis I designed, simulated and coded my own control and estimation loops for a drone with tilting motors. You don’t even have to be from a Stem background to tune PIDs. They are stupidly simple but for most cases they are more than good enough. And yes I have a mechanical engineering degree (MSc). Anything that I said is wrong?

I didn’t disagree about the costs reduction. First these drones are still somewhat new in what I assume is an old school field. Also expensive af. Second usually they are usually performed by service providers. If a bridge inspections costs X and the provider can do it with a drone for like 1/4, then he isn’t going to charge that. He’s going to charge 3/4 because it’s a win/win situation. And because of the first point maybe you don’t have that many providers. Also because the drones need to be specialized, and not just any drone for aerial photography or mapping. Lastly regulation. That is always a PITA and more so with drones.

Edit: I actually went and read the article and the 30% are not at all related to bridge inspection cost. It’s basically a 30% reduction in some trajectory planning cost function because it takes into account the wind conditions. So yea kind of a useless discussion

First of all the other guy that replied to you wasn’t me. With all that rant you didn’t even notice that.

Second of all I actually work as en engineer in the Drone industry. I’ve written flight control software so I know a thing or two.

Third I actually know people working with drones in that specific industry in two different companies actually. In both cases these drones aim to get as close as possible to their target in order to do the inspection because that’s required. If a bridge has a crack that hasn’t been spotted and is already visible from a far, that bridge is already in a bad state. You are looking at basically micro gaps in your preventative maintenance. And no these aren’t 1k consumer grade djis (though DJI has fucking amazing hardware). I’m talking 5 to 6 figures and sometimes that just a lease.

Lastly that’s all very fancy math for vibrations. You should go work in state estimation if you can cancel it that easily. In the real world you have vibrations across the entire spectrum. Yes there are certain peaks and one of them is related to the motor rpm but it’s an extremely complex problem. Gimbals aim to stabilize the feed from a attitude pov with some damping but they aren’t foolproof.

It’s not just resolution

Its also stability/focus and speed

Get the camera with highest zoom you can and plop it in a drone and you will get shitty photos. Drones have a ton of vibrations.

When you do bridge inspection you have to be real close to the structure. And basically stationary as well. You are looking for minuscule gaps and other damages.

You can easily do a 3D map from afar but that won’t have anywhere near the resolution required.

I read your comment, then I read the article. Well said
