  • No one “shatters,” “breaks,” or otherwise surpasses violates the diffraction limit. Rather, you operate in such a way that the diffraction limit does not apply.

    This is not to take away from these accomplishments at all! All manner of super resolution techniques are fantastic, but they’re not violating the diffraction limit; they are violating the assumptions that go into the diffraction limit, or they are using a different definition of resolution (which is completely valid), or both.





  • I had an…interesting…take home exam in college. The max score was 100, but the test had 200 points. So, if confident, you could answer half the exam and still get the highest score; if not confident in answers, you could answer more questions and rely on partial credit

    It was a week long take home, “open everything” (book/Internet, but no discussions online or IRL). In some ways the hardest exam I ever took, but I learned a lot, and some of the questions were specifically meant to introduce new subjects.

    If you really want to try some, you could use d-limonene. It’s just orange oil (like you get when you squeeze an orange peel), is edible, and is basically a kerosene-like hydrocarbon. It’s used in hand soap and works for stripping paint, and you can run multi-fuel camp stoves off of it, too!

    Careful ingesting it though, as it isn’t always food grade due to extraction methods/additives. It causes kidney tumors in rats, but the mechanism is known and is not relevant to humans.



  • Lots of local-only options out there for security cameras. Doorbell cameras may be a little harder to find, but it looks like they exist.

    I have a few Amcrest PoE bullet cameras, and they work great local-only. They’re on a separate VLAN, only my server can talk to them, and I have had zero problems with them. They even support NTP, which my router provides, so the clocks stay synced with no intervention. I’m running them with Frigate.
