Calling on #mastodon #train nerds! :-) 🚊

Today student groups are visiting our company. One group received funding (75k euro) to investigate how high speed rail can cross non-overhead-electrification gaps on battery.

Their brief states "TGV style train", 300km/hr cruising speed, and 100km battery range.

A very quick thought experiment makes this sound impossible to me (numbers in next post) as the batteries replace passenger capacity. And costs. They disagree.

Am I the idiot here?

Question for #plant #biologists that might be in my network:

Q: I grow batches of #sequoia. About one quarter of seedlings form little water drops on the tips of the first leaves / cotyledons. These stay in place for about two weeks. The rest of the seedlings do not show any of this.

I assume this is some type of guttation. Any I'm loosely theorizing it has to do with how the cotyledons were split, maybe damaged. But frankly, I don't know :-)

Any insight from 🌲 🌱 #science people are welcome!

Ha. Groningen cannot find anyone to build hydrogen trains for them https://www.railwaygazette.com/traction-and-rolling-stock/no-bids-to-supply-hydrogen-trains/65818.article

How about using a battery?
Or better still putting up wires?

I'm in a #bookshop trying to decide. Have 20 minutes:

Flow my Tears, the Policeman Said (Philip K. Dick)

vs.

The Left Hand Of Darkness (Ursula K. Le Guin)

You're my only hope #askfedi! ;-) #books #reading

Danish train conductors don't take shit from impolite people. A woman who started vaping inside the train was just kicked off without any discussion.

"I didn't know, you didn't give me a warning"

Yesterday I* saw a badger! 🦡

When was the last time you saw a wild mammal near your house/garden, and what was it?

Please mention where you are based.

(I'm wondering about wild mammals, not house cats/dogs and birds as I assume you all see those regularly).

*Denmark, house in a woody rural area.

Edit: boosting this again, it's already been fun reading people's experiences! And not unsurprisingly Australia had the weirdest mammal 🙂

TIL about "gorpcore": https://en.wikipedia.org/wiki/Gorpcore

I´m finally fashionable! (Along with roughly 30m other Germans. We´ve been doing this for decades!)

How to #host a website in the #newyear? I have a feeling the #fediverse is a good place to ask 🙂

For decades I've had a hosting account with #Godaddy. Due to changing interests & lack of #ssl traffic is down to a handful visitors daily. Hence I will shut it down.

I do want to keep the domain and host a very simple landing page. Maybe just static HTML on a https connection.

I want to keep it simple and am willing to pay (a bit :ablobcatrave:). Where do I start?! Help is much appreciated!

So much #gardening today!

As the weather for the upcoming week is predicted to be "mostly water themed" (rain, snow, fog: assorted humidity) it's the perfect time to transplant some #trees from #nursery to the #woodland.

It's not ideal to transplant so early in #winter (there will be -0 cold snaps) but at least they won't be transplanted right before the now inevitable early spring 4-8week #drought Denmark gets. #ClimateDiary

Photos: about 50 horse chestnuts 🌰. To be planted tomorrow!

The now empty plot where the trees enjoyed their childhood. Now to figure out what next to plant there :-)

Here's my #ChristmasTree for y'all! At the base, one of the Auxiliary Telescopes at ESO's Paranal Observatory. Above it, the Magellanic Clouds, two small galaxies orbiting our own. The tree-topper is 47 Tucanae, a globular cluster containing millions of #stars.

The light from this and other telescopes can be combined to get the same level of detail as that of a huge "virtual" telescope using interferometry: https://www.eso.org/public/teles-instr/technology/interferometry/

My grandmother passed this year. She is one of the women who taught me how to sew by hand as a child specifically and how to be a self-sufficient craftsperson generally.

For my 8th birthday she gave me a quilt, like she did all of her grandchildren. I've minimized and thrown everything away to start fresh moving somewhere else several times in my life and it's one of the only things I've managed to keep around. All of my cousins stowed theirs away somewhere, or have them on display in some way or another, but mine has been keeping me warm since I was 8 while I've patched and mended it along.

This Christmas my mom gave me a pin cushion my grandmother made and she was taken aback that I went straight to using it and sticking pins in it instead of preserving it and displaying it. It's going to be my new main pin cushion.

Not everyone shares this sentiment, but I think the best way to honor any craftsperson is to use their gifts and creations, and use them well.

I don't want my grandmother to be a museum piece, carefully handled and sealed away like she left the world: in a distant hospital bed. I want her to be there with me every time I make use of all the knowledge and self-empowerment that she shared, like she lived.

This is a new one for me but there’s something black(I’m assuming mold) in one of our #lego #advent calendar bags.

Oh shit. I found an old friend on LinkedIn yesterday and sent them a connection request.

Now LinkedIn knows I’m still alive, and has started sending me notifications multiple times a day to remind me that I’m supposed to have A Career.

Fuck LinkedIn and whoever rides with them.
