This somehow reminds me of the fact that you can produce (surprisingly high-quality) x-rays by unrolling scotch tape in a vacuum chamber[0][1]. I wonder if it turns out to be related in any way. Thunderstorms aren't a vacuum of course, but I dunno, maybe all that frozen hail being thrown around can bumping into each other still involves a similar underlying mechanism somewhere.
I agree that the title is click-baity, but the spirit of the video is about showing no-budget solutions exist, without the need for any specialized equipment. The cheapest tiny electric kiln I could find with a bit of quick searching is still over 1000 dollars[0]. Which is a much higher up-front cost than [checks video] 21 bricks, some sand, a small metal bucket and a bag of charcoal.
Also, if your apartment has a big enough balcony where you're allowed to put a barbecue, then this approach is just as viable as an electric kiln.
Some of the things I liked about VB6 that are not widely done well today, IMO, are (A) the RAD GUI builder (B) small, native binaries (C) deeply integrated, language-agnostic RPC framework
Sadly, Joe Huckaby (who implemented the web-based demo) never got around to finish the promised drawing tool. I wonder if any other pixel art programs since then have added interface support for color cycling.
> However, here the author seems to accidentally fully recompress the images, and falls into the classic trap of "looks almost the same but the file is much smaller!"
Except they didn't quite do that: yes, they recompressed the image instead of using the lossles rotation that JPEG is capable of. However, they then compared a recompressed rotated image to a recompressed image that wasn't rotated, and noted there was still a significant size differnce.
He also claims to have verified in GIMP that the two recompressed files were visually identical after rotating (I'm a little suspicious of that bit, since you wouldn't notice a tiny difference unless you use the "difference" layer mode and theo manually amplify the miniscule differences with something like the curves tool)
Yes this is the crux and the fun of my discovery! I was surprised how using sips to rotate the image resulted in a lower size than using sips or ImageMagick to directly compress the image.
I’d encourage you to download the image from the link in the article and try yourself if you have a Mac and then compare them with GIMP because it’s very possible I didn’t do a perfect job with that.
See my other comment for the result from ImageMagick, which shows little difference regardless of the orientation. For sips, there is a possibility that chroma subsampling impacted the result (because there are two different scaling factors for each axis) and you are technically comparing different images.
I can't answer your question, but on a meta level I would suggest to use "well established" instead, since that is less ambiguous about referring to scientists or other domain experts agreeing on something for various reasons.
"Well known" could also be intended to mean that something has become common knowledge among the general public, which I don't think applies here.
Let's not be flippant about something GP didn't actually say.
The Polynesian people aren't native Americans; as far as we can tell all native Americans came to the continents via the Beringa land bridge in the last glacial maximum[0][1]. However, as others mentioned there have been multiple reasons to believe that Polynesians and native Americans had contact, and this would be more genomic evidence pointing to that.
The comment you replied to said European Colonialism, not European Slavers.
Were these Peruvian slavers native Peruvians, who acted in accordance to the culture and society they had before Europeans arrived there? Or were they people who had moved to Peru from Europe as colonizers and who decided to keep the system of European colonialism after it became independent?
