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...

Some #Twitter things that the company didn’t build or invent itself:
• Twitterrific was the first mobile Twitter app
• The word tweet made its first official appearance on Twitterrific
• The hashtag was from Chris Messina
• Advanced Twitter Search was originally Summize
• Twitter bought TweetDeck
• Live stream was from Periscope acquisition
• The official Twitter app was originally Tweetie which they purchased from Loren Brichter
• Mentioning people with an @ was user driven and wasn’t linked to accounts because they didn’t consider conversations to take place on Twitter initially
• Quote tweet was adopted from people copy+pasting tweets and adding RT in front of the copied tweet
• Threads were built to accomodate existing user behavior
Did I miss anything major?
[update 29/1] lots of additions in the replies that I thought should get added here
• Image attachments added after third party services like imageshack/yfrog, and twitpic became super popular.
• Twitterrific was first to officially associate Twitter with a bird
• Retweet was adopted from user behavior (you couldn’t comment or add context using the official retweet so many people kept using RT until Twitter introduced native QT)
• Scheduling, posting across accounts, and team/shared accounts were from Hootsuite
• Popularity of short link services like isgd and bitly lead to tco url masking
Something that people may not have been aware, in my corner of Twitter in those early years, people interpreted RT not as retweet but as reply to. So they weren’t replying by hitting the reply button but by manually quote tweeting and adding RT after their response.
There’s enough confusion over RT so I’m gonna add this example
#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

@jensclasen close to “Morn’n”
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!

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!
"Cistercian Numbers" are incredibly cool
It's a rare numeric system designed by 13th century monks
Each number is a based on a single vertical stick, with patterns you draw in all four quadrants off it -- top right, top left, bottom right, bottom left
A single glyph can represent a number from 1 to 9,999
