If your community/organisation/company is interested, I am keen to give on-line talks about #FrugalComputing, aka Low Carbon and Sustainable Computing.

Example topics are:

Frugal computing
On the need for low-carbon and sustainable computing and the path towards zero-carbon computing.


How to reduce the carbon footprint of your digital lifestyle


Frugal computing: developer perspective
On the need for low-carbon and sustainable computing and what developers can do about it.


But happy to discuss specific topics in this area.

(boosts much appreciated!)

tim hunkin's secret life of componets 

I made my way through his secret life of components series. I can tell it's something I'm going to enjoy revisiting again and again. So much great information, but just watching him mess around with all sorts of stuff has been incredibly inspiring, too.

The series: youtube.com/watch?v=6JAgXz6xO0

I started learning how to play recently. I'm really loving it, I wish I had started years ago.

As a beginner I would be very interested to hear about others' drumming journeys.

"Hundreds of billions of dollars in direct financial support is received by the producers and consumers of fossil fuels every year – but they benefit from far larger subsidies by not paying for the harm burning fossil fuels causes. When the damage from the climate crisis and air pollution is accounted for, the fossil fuel subsidies reach $6tn a year, according to the International Monetary Fund (IMF). Guardian analysis shows this is equivalent to $11m a minute globally, $4m a minute in China and more than $1m in the US."

Ich bin ein grosser Fan vom Vertical Farming & deshalb ist dies auch die Infografik der Woche in meinem aktuellen Newsletter 👉 https://www.metacheles.de/p/metacheles-8-erdbeben-erleben?s=w

In Japan kommen seit Jahren grosse Teile der Salatproduktion aus den vertikalen Farmen & ich frage mich echt, warum nicht jeder Supermarkt unter der Verkaufsflaeche solche Systeme nutzt.

- Keine Pestizide
- Hoehere Ernte
- Keine Transportkosten
- Geringerer CO2-Fussabdruck

Das ist keine Raketenwissenschaft! #Nachhaltigkeit #Lieferketten

Any bandcamp recommendations welcome – I tend to post music there and leave... I find it too daunting to try to filter bandcamp to find something I like. But I would like to support other artists.

trying to give away 17+ arduino UNOs and components(please boost) 

i used to work with intro cs education and amassed these small arduino kits we put together for a failed project. kits contain (full list below) an arduino uno, breadboard, jumpers, leds, resistors, etc. i've been carrying it around for a few years and want to give it away to people who would actually use it.

so im giving these away to anyone who wants them shipped. ideally i would give away the whole lot to someone, but if no one wants the whole lot i'm willing to ship out small individual packages. covering shipping costs is appreciated but if you can't that's okay.

please respond to this or dm me if you're interested in the whole lot or any smaller amounts!

- 24 small component bags
8 220Ohm resistors
4 200Ohm resistors
2 10kOhm resistors
4 LEDs: white, blue, green, red
1 laser diode (I can check details)
1 photoresistor (I can check details)
2 small push buttons

- 18 64x(?) jumper bundles
- 19 USB A to B cables
- 17 Arduino UNOs
- 20 medium breadboards

- 1 box of random cables, breadboards and jumpers of different kinds

Hey! If any of you new, or old, users started using #Tusky recently and appreciate it, please consider donating a little coin.

Currently our only expense is paying for the work I do, at a set amount each month, and some hosting / domain stuff.

But the tip is always welcome! We even have a tier for $1/month (once a year)! Which I thought was pretty nifty.

I have encountered more image descriptions on Mastodon in 24 hours than I have in Twitter in a couple of years. Seriously. I'm not exaggerating.
As a blind person, this means a lot to me. If you read this and you describe your images, thank you so, so, so much on behalf of all of us. If you don't, now you know you'll be helping random Internet strangers make sense of your posts by typing in a few more words than usual.

I'm working on an introductory #book about #decentralisation protocols. 🦄

It serves as a taster for different technologies, and provides you with a path forward to deepen your studies if you're so inclined.

I'll cover #ActivityPub, #Hyper, #IPFS, and #SSB. Each chapter is a brief intro and a hands-on project using #JavaScript.

The book will be CC licensed. If that sounded interesting, add yourself to the interested readers list at:
