dvh··on Lunar Terminator Paradox
> Now, what happens if the moon is not at the horizon, but higher up at the sky?

Moon follows the sun to the west so to move moon "higher" up in the sky you need to rewind time (15deg/hour). In e.g. 4 hours moon barely moves in it's 28 day cycle so the moon will look exactly the same (you can take a picture and compare). It's the earth rotation that make moon "go down" or up. I've read your article 2 times and I still don't understand what is apparent problem, no wonder AI had trouble. Also it's hard to reason about up and down when moon move along ecliptic which is curve. Down at noon points elsewhere as down at sunset.

dvh··on Show HN: Make cursed fonts like Times New Bastard
For extra fun, you can make font that are the same as original but then you add ligature for some words and you make ligature using the same font but spelling different word. For example "red" ligature will be "green".

dvh··on Truman World
If you opened page and haven't seen video, the page malfunctioned, try reloading it.

On the page there is streamed real time video that is generated by ai. The setting is similar to the movie Truman show with Jim Carrey where he was main character whose life was streamed 24/7. With the limitations of current technology, it is inconsistent slop, the consistency is at most 5-10s, they probably just generate first and last frame of a 10s "scene" and make 2 videos and then stich them together. There is some monetization scheme where users can steer what's happening on screen by paid prompts.

dvh··on Eating Fruit Skins
I had a college who would meticulously cut that black thing at the bottom of the apple and also quite a bit of actual apple flesh, like 1cm or even more around it. When I asked him why he cut so much, he said that the black thing is remnant of apple flower and when apple tree is in the bloom it is the most sensitive so they apply most pesticides then and the concentration is highest around that black part. By cutting it away with little bit of flesh he removes most of the pesticides that are in the apple. It didn't help, few years later he died of cancer.
dvh··on Forgotten Woodlands
Speaking of forgotten woodlands, I've talked about this on HN two times already, might as well say it third time. Go on Google maps and look at the size of the Sherwood forest. I've never truly recovered from that experience.

Could this be used to estimate how many fingers LLM have?
dvh··on Bill Gates tries to install MovieMaker (2003)
In 2002 after spending my first 30 minutes on windows XP (previously 98, 95 and 3.11 user) I realized that Microsoft will never improve their UX. Every new os will be different, but not better. So I left then and there and never looked back, after some distro tourism I settled on Ubuntu in 2006 and use it even now.

dvh··on Babylonian Lamb Stew with Beets (1750–1730 BCE)
Apparently their beets looked the same as ours:

> The kind of beets used in such an ancient recipe should not be different from the beets we use today, even in name. We read in Dictionary of Assyrian Botany (by Campbell Thompson, 1948) that in the ancient Mesopotamian region it was called ‘shumundar,’ it was as red as blood, and has a spinning-top shape (pp. 49, 51).

dvh··on Git hosting that never leaves Europe
Published repos are for collaboration.
dvh··on Can guitar frets perform multiplication?
Take a guitar. Very gently put finger on string. Start sliding finger while continuously strumming with other hand. On some places (usually 3rd 5th 12th fret) the string will produce clean sounds, that's where the frets should be.
dvh··on Git hosting that never leaves Europe
You shouldn't allow repos without descriptions. Do people really cannot be bothered to write one sentence that describes the repo?

Alt text: "You legs may have a comparative advantage at running, but we arms have a competitive advantage at swinging hammers, so unless you accept that we're the dominant limbs and stop hogging the oxygen, that running advantage won't be around for long."
dvh··on Your Open Source Model Could Have a Hidden Time-Release Backdoor
I can imagine scenario. Let's say you tell open-weight model to generate kitten video. It uses piezoelectric effect of some ceramic capacitor on gpu as microphone and adds recorded audio to the generated video in non audible range. You post kitten video on social media where ai company collects it and extract what you were saying while the video was being generated.
