“A team of researchers at the University of Cambridge successfully replaced a battery with algae to provide continuous power to a microprocessor.
“The tiny system is roughly the same size as an AA battery and runs an ARM Cortex M0+ processor. However, rather than sipping power from a rechargeable battery, the researchers used a non-toxic blue-green algae called Synechoycystis to naturally harvest energy when exposed to the sun through photosynthesis.”
A reminder that Mastodon and the Fediverse do NOT use cryptocurrency, blockchains, NFTs, tokens, coins, mining, web3 or anything like that.
Masto and the Fedi run on traditional servers and use a sustainable network federation model somewhat similar to e-mail (that's why Fediverse addresses look similar to e-mail addresses).
Also a reminder there are no venture capital firms or other investors either. No one owns the network, each server is independent. Masto and Fedi server running costs are paid by their owners, sometimes with donations from users.
No one is getting rich from the Fediverse, it is all volunteers with some getting donations and a few getting modest grants from foundations. Please remember this when you interact with admins or developers.
(There might be some individual users who post about cryptocurrency/blockchain, but the infrastructure this place runs on doesn't use it at all.)
Tl:dr - Decentralisation does NOT mean cryptocurrency/blockchain
I've been tentatively tooting for a few days now, so I guess it's about time I did my #introduction !
What seems like a lifetime ago I studied #physics at uni (I have since forgotten most of it!) with a real interest in #cosmology. I do get outside some nights for #astronomy 🔭 but I'm mainly a fair weather astronomer these days.
Oh, and I'm not actually a sentient teapot!
Look forward to tooting with you!
Decentralization is not the goal. The goal is information and communication services that respect human agency.
Open source is not the goal, the goal is building a commons of software that is free to study, inspect, and improve.
I feel like, as implementors, as people who spend our lives in the digital crawlspaces focused on the details; its easy to lose sight of the why behind the how. I think important to periodically step back and refocus on why we are doing things the way we are doing. What is the desired world state?

NEW: We analysed 136 popular web pages about mental health in France, Germany and the UK and found that websites share users' personal data with advertisers and other third parties. Some also leak depression test results.
Ok. I know I prefer to post some errors on-line than to have an add-on that will send all my data to cooperating websites.
Shifting from behavioral, targeted advertising to contextual advertising "need not reduce profitability"—and would protect user privacy—writes the CEO of search engine @DuckDuckGo in the @nytimes https://www.nytimes.com/2019/06/19/opinion/facebook-google-privacy.html
