  1. Bird Sun Dog

    Have you ever seen a little rainbow off to the side of the Sun? Rare but rewarding to see, such spectacles are known as sundogs, mock suns or parhelia. Sundogs are just sunlight refracting through hexagonal falling ice crystals in the Earth's atmosphere. When thin ice crystals flitter down nearly horizontally, they best refract sunlight sideways and create sundogs.

  2. It’s been a good evening for #SunDogs in the UK.

  3. For this week's Time Lapse Tuesday we have an example of sun dogs. In this time lapse from last Friday afternoon, you'll notice a bright, colorful spot to the left of the sun. This is caused by ice crystals in high clouds that refract the light into the colors of the spectrum. You can also see a halo around the sun at times, also caused by refraction.

  4. #SkyingHour A4 I often glimpse upwards to do a little bit of #Skying – am always looking for #SunDogs when the weather is right. Always look up to see what #Stars & #Planets are about – & at the #Moon  I am spending more time consciously #Skying nowadays though. Setting aside time & brain space.

  5. Nice and 22-degree halo this afternoon. (With St. Peter's Dome in the background.)

  6. Noodles and sundogs and pyramids, oh my! Thank you to Q2 viewers Stacey, Sherri, Suzanne, and Bob for your great photos of our cold, beautiful weather!

  11. Some more #AtmosphericOptics from #Oxfordshire on 17th July 2023. We had a nice #22DegreeHalo and really bright #parhelia (#sundogs) which had a bit of a #ParhelicCircle tail. I always love getting aircraft flying near sundogs! #OpticalEffects #IceCrystals #Haloes

  16. Spotted a nearly complete circle rainbow around the sun with a pair of sundogs while doing a grocery pickup.

  17. Rainbow's End

    I've always been fascinated by optical effects, especially those involving colour splitting. Over the years I've made a collection of images of them, and I'm sharing some of them with you today.

    Taken from home in #Scotland, these are #parhelia or #SunDogs formed when ice crystals in high cirrostratus cloud refract the light and it splits into coloured bands.
    These two look quite a lot like feathers, I think.

  18. A halo, sundogs, a sweet Skittles gummies rainbow, two feet, and some guy in blue...

  19. #mastodon is very stable in terms of memory consumption!

    But I'm thinking about what we're really doing here in #fediverse and I'm comparing it with, let's say, resource footprint of #circumlunar community (Zaibatsu / ... / Soviet) and realise that their footprint is kind of zero.

    Everyone is on one of the three manually federated servers, using UNIX / pre-UNIX tools to communicate with each other, with the only non-UNIX tool being IRC.

    Somehow it doesn't take 2GiB of memory and somewhat constant CPU load for #sundogs to exchange bytes.

    I get that to host huge instances like mastodon.social, it makes sense to have #pgsql, but it feels like individual instances should be able to be cohosted on the same machine.

    I'm committed to explore using file system and files for #doauth persistent storage backend.

    But that also brings me to a dilemma of whether or not to use #elixir for the rewrite or to use #rust, to decrease footprint.

    Obviously, #elixir will yield more stable, fault tolerant code with easier replication. #Rust, however will reduce excess footprints to 0 at a cost of longer development time (I'll need to benchmark current #tokio-based HTTP servers and see if I need to write my own dead simple server that doesn't use generics / isn't bloated), and it can easily eat up a month of my time.

    Maybe it's all non-issue, especially if there's just one BEAM machine launched per host and we plug our applications into it (as intended)...

    I think that the fact that I'm heavily leaning towards #elixir as the main production technology even though "close-to-metal" argument is important to me is a clear sign I should use it for production in #doma.
