µ-Posts (What is this?)

The people working in Univalent Type Theory (also known as Homotopy Type Theory) will tell you that its advantage is that you can work with equivalent objects as thought they were equal. But I think the opposite is true. Since you need to compose the proofs of equality everywhere, you're effectively working with equality as if it was just an equivalence 🙃.

A great video by TechAltar on what has the GDPR achieved in the 3 years of its existence https://www.youtube.com/watch?v=v_W0wR4AClk.

Google banning Element.io from their Play Store because of suspicious content on Matrix network. This is the same as if they banned some e-mail client because they noticed that people share misinformation that way.

Meanwhile Element.io have written a blog post about the story.

There's a growing case being made with each passing year that if there's hope for the social web, it's in small communities. It's built on protocols like ActivityPub, rather than on one-stop “gated” (i.e. proprietary) platforms. Whereas our social giants are built from the start for unaccountable inequity, a web of small, connected communities has the ability to give us true “town squares” run by humans and organizations that are closer to their users, and answer directly to them.

Big news: My friend William DeMeo has announced that he's formalised Birkhoff HSP Theorem in Martin-Löf type theory using Agda. Details on ualib.gitlab.io.

A lot of people are switching from #WhatsApp to #Signal these days. I don't like where it's going. Messaging should be as decentralised as e-mail is, otherwise we're heading to the same problem as we had with WhatsApp. Who guarantees that Signal won't be acquired by somebody we dislike in the future? For example, Matrix is a better alternative as its decentralised protocol guarantees that it can't be fully owned by anyone. (And there are possibly more options.)

Just received a YubiKey from CZ.NIC (in exchange for writing about it with #overenomojeid). After setting up the two-factor authentication in mojeid.cz I can easily manage my citizen profile. It's great to see some progress in Czech "e-governance".

While being stuck in England because my flights were cancelled, I watched a Moshe Vardi's talk that aptly argues against Cyber Libertarianism, why we can't reach (economic) equilibria and more. His OWLS talk is here youtu.be/BipEbkdbVNc.

IT'S OFFICIAL: @gitchat@twitter.com now natively speaks Matrix!! Read all about what it takes to add native Matrix support to a large existing chat app, and bask in the glow of a world where FOSS chat is increasingly FOSS, open & interoperable once more :D 🎉🥳🍾🌉🚀 https://matrix.org/blog/2020/12/07/gitter-now-speaks-matrix​

I'm just incredibly tired of having to deal with the cookie pop-ups everywhere. Is there any legitimate use-case for third-party #cookies, apart from advertising? If not, we should just finally ban them (legislatively). Those that want to track us will use browser fingerprints anyway...

"Parliament wants to boost #sustainability by promoting #reuse and #repairs and by tackling practices that shorten the lifespan of products."

A huge win for the #RighttoRepair 🙌 🛠️ : https://bit.ly/3misaVW​

Okay so Google killed their Buzz, Wave, Talk, Picasa, URL Shortener, Google+, Hangouts and now essentially even Photos. I'm leaving Google unwillingly more and more every year. I wonder which of the last products of Google which I still use (Google Scholar, Translate, Drive, Maps, Youtube, and Android) is going down next...

Mental note for myself: restarters.net have a great wiki https://wiki.restarters.net/, full of tutorials and other material for people that prefer to repair laptops, phones and other electronics rather than throwing it away.
