#DARK #ERUPTION ON THE #SUN: One of the most dramatic eruptions of Solar Cycle 25 occured yesterday, July 14th, when a spray of dark #plasma flew away from the sun's southern hemosphere. NASA's Solar Dynamics Observatory recorded the event:

The explosion started in the magnetic canopy of AR3370, a small and previously unremarkable sunspot. X-ray sensors on Earth-orbiting satellites registered a C8.8-class solar flare at 1844 UT just before the dark ejecta appeared. Why dark? The plasma was #relatively #cool and #dense, and silhouetted the glow of the underlying sun.

This explosion probably hurled a #CME toward #Earth. Confirmation awaits fresh data from SOHO coronagraphs.

THIS SUNSPOT IS BLOWING BUBBLES: Big sunspot AR3363 has an inky-black core wide enough to swallow Earth. What is going on in there? On July 11th, a Dutch astronomer nicknamed "Neo" decided to take a closer look, and this is what he saw:

"I captured a phenomenon called 'umbral flashes,'" says New. "Rapid bubbling from the depths of the Umbra is shown in this timelapse movie, which I created from 11 minutes of raw video."

The umbra of a sunspot is its dark central core. It is where magnetic fields are so intense, incandescent heat from the underlying sun is bottled up and prevented from reaching the surface. That is why sunspot umbras look dark.

Yet they are not completely dark. Professional astronomers have long known that flashes of light and popping bubbles can be seen in sunspot cores. These events are not fully understood. One theory holds that gas from the sun's atmosphere falls into the umbra. When it reaches the "floor" of the sunspot, the gas rebounds, forming luminous shockwaves that observers describe as "umbral flashes."

What #Mastodon #server could I #choose?

It's a real #problem you don't know much about the #administration of the servers. A Mastodon server could be a "Trojan Horse" to get your data. Now that they are leaving #Twitter many new servers appear and many admins will close their server next year again because it's too expensive or too much #work.

So here are some points you can check:

  • Don't go to #fosstodon because I am there. Choose fosstodon only if most of the ther points of this list fitt your needs.
  • The donain of the server shouldn't include "Mastodon" because most of the new users search their server via #Google. If they all choose servers with "Mastodon" inside of the #domain it's against #decentralization and the servers are soon overcrowded with much work for the administration.
  • Check the server #information and #background. It's better to choose a server operated by a #community and not a single person. The server should have been only before the #hyoe because not many of the new servers will survive one year.
  • Check the domain. It should be #cool and fitting to the spirit of your posts.
  • Check the servers blocked on your server. Don't choose a server where nothing is blocked because then you know there is no #moderation on your server. If right wing servers are not blocked you are maybe choosing a server of a right echo chamber. If your server is blocked on many others there is something wrong with the administration.
  • At the end its the best to open your own server and be your own #admin. But don't forget that Mastodon isn't running properly on a raspberry pi. The server needs money and time for updates and moderation. So think of donating to your server if possible.
  • Learn about the #Fediverse. You are here on #Diaspora and now you think about going to Mastodon because Elon #Musk is killing Twitter. But why should you go to Mastodon only because the #press #filterbubble is talking about it? Maybe you can be wiser than all the lemmings out there and learn something first with a search engine of your #trust. With #Friendica you can post to the Fediverse and read it on Diaspora and Mastodon.
  • At the end it would be nice if you can follow me on Mastodon: https://fosstodon.org/@anonymiss - @anonymiss@fosstodon.org :)

Please let me know what you think in the comments and thank you for reading :)

" #Revolution" - The #VideoToaster #Demo #Tape ( #NewTek) - #Amiga

The 1990 video that started it all. Made you feel like you could do #video #effects like the big #television #networks. No big deal these days, but back then the barriers to entry for doing #professional video were huge.

This video comes from the #VHS tape we ordered through the mail back in 1990, just to watch all the #cool #computer #animation, and then dream about owning something like this someday.

And just like these guys did, we've used cutting edge #visual #effects #technology to enhance and upscale this video to HD, making it look better than it did in 1990. We share it here as a thank you and a tribute to the "with it" guys, and Kiki Stockhammer for creating this paradigm shift!
