Seconding Matrix, if you like the idea of chat rather than forum post format. You can also use the account in the Matrix network at large, quite a few techy hobby groups there, and of course one-to-one chat.
Hope it's Fairphone.
Western society tried to enforce cleaning and actually progressing in one of my abandoned projects, maybe some light reading, on me? Because that's what I wanted to do. In stead the day just kind of disappeared.
The latest version of Ubuntu Touch is testing encryption. Just in time.
Yesssss, finally. Wish I had my FP4 with me to try.
Endless Sky is wonderful, though the mobile version is a bit clunky (not even an "official" version afaik, but stitched on the ongoing-development FOSS game).
According to Wikipedia, the planetary boundaries -concept has been around since 2009, with some renaming and one variable change ("chemical pollution" to "novel entities". The original Nature (feature) paper that I dug up doesn't describe the methodology, but that it hasn't faced major criticism so far would suggest it's pretty valid for the kind of tool that it is.
I may be slightly envious.
Clay teapot.
Aged sheng pu'erh tea cake.
A good steep of a dan cong tea (so rare).
Live opera experience.
Vegetable patch.
Slushie.
My favourite pair of shoes (I did).
Alpaca/silk dress (yup).
Orgasm.
To be fair I always wanted more than one cat, just had to start with one.
Device-wise, have you considered separating your project and personal computer? You could coreboot a small light Chromebook as a personal, ultraportable device, and get a hefty laptop or even a desktop for the hard stuff.
Chatwise, there's Matrix, XMPP and SimpleX at least. And Briar and Session. But Signal with its phone number registration is the easiest for others to jump to.
And yes, it's a constant balancing act between privacy and convenience... and the IA of the security triad, and open source principles. Just like with most things, there's no perfect solution, you just learn to live with the least bad ones.
