Anything older than about 30 days shows only month and day, so a gallery from 2019 reads "Oct 22", same as last October. Backfilled galleries (Instagram imports, old event photos) make th...

Not totally sure if the resulting conclusion of this is that A) AI will be able to do everything (mediocre, but still), or B) that AI will be able to not do anything. Leaning towards A

I very much assume it's the former, but when first reading the domain I also very much read PLC+red 😅

Hoping it's still early enough to ask the really stupid questions: Is the last -cred part of the domain short for "Credentials"... OR... Is it PLC + red and in that case what does the red stand for 😂

Im finding @gui.do's 2048 to be a little addictive. It's the familiar faces. Reminds me of the feel of the time when Facebook first opened up to apps 20 years ago and it was all farmland for awhile.

Well there's @comail.at 😅 But I don't necessarily mean you need to host your own E-mail server, I'd actually advise against that for most people. But you do need to own your own E-mail domain, so that when your E-mail provider enshitifies, you can easily move on

Guido X Jansen @gui.do · 26/09/2026
Any domain you can get through @marque.at works! 😄

All these principles do assume one thing: that you control your own digital identity. Your email address (and the domain it belongs to) is the key to everything else. If you don’t own that, you risk every aspect of your digital life being controlled by someone else.

1) Own your data, or at least be able to leave 2) Prioritise open standards 3) Local-first, cloud-optional 4) Apply the bankruptcy test 5) Resist subscription creep, but accept strategic subscriptions 6) Favour EU-based and privacy-respecting tools 7) Replace gradually, not all at once

What should be on the 2027 @atmosphereconf.org clogs that @bmann.ca will be wearing for 4 days? Goostopher? Stroopwafels? Embedded PDS?

For those who though I was joking about wearing clogs at @atmosphereconf.org: here's picture proof of me at Magento Live 2019 co-hosting the event. Last one in the grass is from today: clogs are durable! (also because I don't wear them like ever because it hurts like hell)

"Sea borders come mostly from the UN Convention on the Law of the Sea (UNCLOS, 1982). Two countries share a sea border when their zones overlap, which happens whenever their coasts are less than 400 nm apart."

Do you also want "fun facts" in here? Like "The Kingdom of The Netherlands has (land and sea) borders with these other countries:" * Germany * Belgium * United Kingdom * France * Venezuela * United States * Saint Kitts and Nevis * Dominican Republic (possible...)

Re 6 (Coalition charter): A public pledge from relays, AppViews and labelers: no preferential treatment, full export, a notice period before defederating. Set the right standards now (even those that aren't really enforceable)

Re 5 (regulation): DMA interoperability duties for gatekeepers who enter the Atmosphere, plus DSA.

Guido X Jansen @gui.do · 25/09/2026
Re 4 (Licensing as a weapon): Maybe use AGPL on backends instead of MIT to block closed forks. Consider a conformance trademark ("Atmosphere-compatible" to require real federation and export) see Java/Bluetooth
