Speaking of the Forth-Clyde canal, this is Lock 27#Glasgow #photography #autumn

But with its old walls and many beautiful trees, it is a great place for taking pictures.#Glasgow #photography#nature #autumn

Gartnavel Royal Hospital is a strange place: half of the buildings are ruins, the rest is still in use as office space.#Glasgow #photography

And this one on the grounds of the Gartnavel hospital#glasgow #photography#nature #autumn

And some trees in autumn livery. This one at the banks of the Kelvin on Garscube estate.#glasgow #photography#nature #autumn

We are in a mini-lockdown so went on a 20 km walk through #Glasgow to soak up some sunshine and autumn colours. I will post more pictures later, but first these very cute bears, part of a community notice board in Westerton.#photography

On average, a car weighs about 1.3 ton and carries 1.45 passengers, so 0.9 ton per passenger. The N700 Series #Shinkansen weighs 715 tonnes and carries 1323 passengers, so 0.5 ton per passenger. Combined with the lower rolling resistance of steel wheels on steel rail compared to car tires on tarmac (0.002 vs 0.010), the result is that an N700 Shinkansen is almost 10x more energy efficient than a typical automobile. And of course, at 320 km/h, a lot faster too.

If you want to view your #Mastodon archive, there are a few tools:

- A python script that produces a web page with all your posts, with media.

https://github.com/dizzy-labs/mastodon-archive-viewer

- A JavaScript-based HTML page that lets you load the JSON files and shows you some nice stats about your posts, as well as a timeline, but without media

And this is a #drawing of a pensive Tian Tian ( 甜甜), "Sweetie”, the female giant #panda at Edinburgh zoo. Same technique as the polar bear.

Here is a drawing of one of the polar bears in the Kingussie Highland Wildlife Park, in its pond, eating a melon.
It's based on a picture from the BBC news.
I used graphite watercolour pencils on coarse watercolour paper.

Maybe I should promote my #cooking site a bit. It's a collection of #veggie recipes, majority #vegan, quite a few #Japanese too. The focus is on recipes for one or two people that are quick to make (less than 30 minutes).
All my own, all pictures taken just before eating the food.

In close-up the flowers of the Kojo no mai are really lovely, very delicate.

I have written a #guide to help people who want to run their own fedi instance but don't know where to start. It covers the basics of networking, use of command line, Linux system administration, just enough to get you started.

So if you would like to run your own #Mastodon or #Pleroma instance but you find you don't know enough to follow the tutorials, then this guide is for you.

Comments welcome!

Yesterday morning, on my way to work. A clear morning always lifts my spirits.

In case you wonder how to access a #gopher server, it's very simple, open a terminal and use the venerable 'telnet' program. For example:

$ telnet zaibatsu.circumlunar.space 70

Then once you're in, type '/' and hit return. You'll see a list of paths starting with '/'. For example, '/about'. Type that and you get the "about" message, etc.

I was intrigued that #Japanese has kanji for very large numbers (like 極=10^48), so I wrote a blog post about it. It's a story of counting systems, an Edo-era mathematics text and Buddhist scriptures, with a supercomputer and a samurai, so it might even interest you if you are not studying Japanese ^_^

Some scenes of the remnants of the Caledonian pine forest near Aviemore, on a lovely November day.
