Protonmail–I’ve used them for my custom domain email for the last 4 years and have had very few problems (other than needing to recompile the Protonmail Bridge app so I could use it on an ARM server)–I think I pay around $50/year. I selfhost Nextcloud for everything else (files, calendar, news, etc.)
Yes and no. As my physics professor used to say, all models are wrong, our goal is to make the least wrong model. It’s literally impossible to simulate every event. For example, what if there was an anthill under the area where the rock is dropped? Maybe that will affect the resulting sound? Maybe, but it’s not going to make a difference to the observer.
We know enough physics to simulate a huge number of simultaneous events, but at some point a model becomes far too complicated (e.g. taking a week to run on a powerful computer), when a more simplified model will do the trick just fine. I personally compare it to FLAC and MP3–FLAC is of course best quality, but will eat up a ton of storage space, and MP3 (with compression) is good enough
Have you ever considered Father Ted?
I’ve love both Firefox and Okular (KDE’s evince), and both “technically” support PDF inking, but the experience is just subpar to what Edge offers now for notetaking and reviewing articles. Xournal++ is the gold standard and fully supports my Surface Pen, whereas Edge does not recognize pressure or the eraser. However, I work with a lot of embedded files (Logseq), and the fact that Xournal++ cannot bundle a PDF in a single file and instead needs a reference, plus the fact that PDF is a universal file format, makes Edge the most enticing option for now
I use Edge daily–trying to use mostly non-proprietary software, but when I need to annotate a PDF, Edge just works. It’s no drawboard PDF, but it’s free and runs on Linux!
The only solution would be, to create - yet again - a universal alternative to the AUR.
Do you have any tips using KDE Connect with a local VPN (Wireguard)? It works great for me on the same network, but unfortunately fails to connect outside of my network despite one (or both) devices connected to my VPN
