New Commodore VIC-20 Build https://hackaday.com/2023/01/25/new-commodore-vic-20-build/
@danyork I was walking up the stairs three steps from the top when my sister told me “the space shuttle’s blown up” - and reaching the top of the stairs I saw the vision on TV (which was on repeat for many hours).

37 years ago today, the Space Shuttle Challenger exploded shortly after launch. Most of us of a certain age can remember where we were. I was in the common area of a dorm at the University of New Hampshire, watching the 1 TV with another student.
What I did NOT remember, until reading Scott Monty's newsletter today, was that President Reagan was supposed to give the State of the Union address that night, but instead said these power words:

Not only do you need leap seconds to keep solar time and atomic time in sync, you'll need a different kind of leap second to keep Lunar atomic time and Earth atomic time in sync, because mass distorts spacetime. So good luck with that... Defining lunar...

#Gumtrees are my favourite large growing mass within the flora world.
They’re known as #eucalypts and csiro.com.au reports that there are 934 species of #eucalypt trees native to #Australia.
Gums typically grow to a height of 45 m (148 ft) but may sometimes only be a stunted shrub. Alternatively under ideal conditions, they can grow as tall as 90–100 m (300–330 ft).
IMO, they’re an emphatic statement of strength and resilience.
Gums can withstand prolonged drought conditions and still stand tall and present happy and healthy. Their trunks and branches are normally covered in a thin layer of white bark that sheds annually around this time of year (summer time).
Their leaves vary in size and shape, depending on the species.
My favourite are the shape as seen in these photos taken a couple of days ago near #Melbournes #Botanicgardens. They’re long (elongated), 10+cm (4+ inch) long and 1.5-2.0cm (3/4 inch) in width at their widest point.
Their leaves often possess a slight curved appearance, are usually deep dark green and clumped together, facing downward toward the ground, hanging from their branches.
This specific tree caught my eye. Its trunk is mottled with varying shades of whites, browns and greys. It is also pitted and indented along its entire length.
It really is a beauty

@mookie@orangebunny.net question: how well do they work when using for phone calls? My $10 ones are good for quite room@listening, but have an almost useless microphone.

Mastodon founder and CEO Eugen Rochko tells Engadget: “Third party applications are incredibly valuable for a platform because that's where the power users go … it benefits everybody because the power users are the people who create the content that everybody reads.”

The German word "Moin", mostly used in the northen parts of the country, can mean
- Good morning
- Hello
- Good day
- Good afternoon
- Good evening
- Welcome!
- How are you?
- Long time no see
- Oops!
- Bye
So, if you only speak little German, visit the North.
You only need one word to get through the day.
Enjoy our language!
@Fawn@ohai.social there is speculation that Newton included indigo only to be able to have 7 colours (a theologically preferred number), and there are only 6 distinct colours in the rainbow.

Here is an updated light curve from http://astro.vanbuitenen.nl/comet/2022E3 with magnitude (brightness) values of Comet C/2022 E3 (ZTF). This graph predicts a magnitude value of around 5 on Feb 1, at closest approach to earth.
Objects with lower magnitude values are brighter. The human eye can detect objects with magnitude < 6. With a good pair of 10x50 binoculars, one can observe objects at magnitude 11 and lower .

Like other comets, C/2022 E3 (ZTF) has a dust tail trailing behind the comet and a glowing ion tail, pointing away from the Sun, formed from gases ionized by UV radiation from the Sun.
The dust tail is also affected by solar radiation and hence is oriented a bit away from the sun.

Wow, there's innovation in propeller shapes (which i thought we're close to optimal for a century): toroidal propellers https://newatlas.com/aircraft/toroidal-quiet-propellers/ >50% performance improvement at midrange rpms in liquids!
