All of the split units I’ve seen are heat pumps.

Heat pump means that it’s reversible, split package is just the physical arrangement of the pieces.

The last part I think is crucial. These people are going to spend $10 million on a yacht. By getting them to invest in maritime electrics, hopefully we can support the industry to the point that they become viable for industrial uses, and that’s where it becomes interesting. A bunch of people who will never own a boat or work in maritime telling them that it’s useless is just dumb.

To get an idea of how they work, this is a great tool for laymen https://29a.ch/photo-forensics/

Try uploading something from https://thispersondoesnotexist.com/ and see how badly it fails.

I used to work in the field of image forensics a few years ago, right as the GAN technology was entering the scene. Even when it was just making 200x200 pixel faces, everyone in the industry was starting to panic. Everything we had at the time was based off of detecting inconsistencies in the pixel content, repeating structures that indicated copy/paste attacks, or looking for metadata inconsistencies

For pixel inconsistencies, you can look at how the jpeg image is encoded to look for blocks that aren’t encoded consistently. This paper coversDCT and some others. https://scholar.google.com/scholar?q=dct+image+forensics&hl=en&as_sdt=0&as_vis=1&oi=scholart#d=gs_qabs&t=1690073435801&u=%23p%3DKmFtRm3WpQ8J That’s just one example, but it’s ultimately looking for things like someone photoshopping a region out or patching something in.

Similarly, copy-move detection would look for “edges” and “intersections” in images and creating constellations of points, which you can use scale invariant transforms to look for duplicates. This article covers an example where North Korea tried to make their landing force look more impressive https://www.theguardian.com/world/2013/mar/27/north-korea-photoshop-hovercraft

The problem is that when the entire image is forged, there is no baseline to detect against. The whole thing is uniformly fake. So we’re back to the old “I can tell by looking at it” which is extremely imprecise and labor intensive. In fact, if you look at how GANs work, it’s trivial to embed any detector algorithm into the training process and make something that also defeats that detector.

A few days late, but I just stumbled across the community. I know that when I was on meds I wouldn’t eat for days. Without meds, I’m just Homer Simpson saying “ooh a piece of candy” all day

There was a line at the beginning of Bojack Horseman (season 2 I think) that I always think about: “It gets easier every day, the hard part is doing it every day.”

Try to find ways to work exercise into your routine. And more importantly, think about how to still do it when days are tough because you get busy.

Edit 1: I stopped taking meds when I was young back in the Ritalin days. I don’t think I ever quite fit in, but I’ve found that daily exercise helps me channel my little bit of attention enough to sit through meetings long enough to do the parts of my job I enjoy.

Edit 2: Also, Google “Pomodoro Method”. It’s pretty much the only thing I do with my smart watch, and it’s fantastic.

I’m also curious about childhood diagnosed, but stopped taking meds back when Ritalin was a thing. The instructions read to me like I had to be either diagnosed as an adult or self-diagnosed.

My dude, as an elder millennial living with ADHD, I feel like you diagnosing TSwift over there internet is pretty cringeworthy. When you say “… reasons I think Taylor Swift could be ND” you are basically diagnosing her which is weird. Period. Nothing to do with ADHD. Don’t go diagnosing people.

There are a couple of other things to say that just sound better. Think about 1) what you are trying to tell people and 2) why your perspective is interesting. It sounds like you are trying to talk about behaviors you see in Taylor that you identify with, and (2) you identify as neurodivergent (ADHD).

You can make the same post along those lines, and I think you would get a much better response.

The fun part is that the cyber security expert is actually a Trump voter and was excited to vindicate the election meddling story.
