Looks tasty mate!
You don't need a device, you can just buy it from the account on any browser via the play store.
Missing an image?!
Quick example in straight C would be a cell in a matrix. The first pointer points to the row and the second pointer points to the cell in that row. This is am over simplification.
I would recommend looking into Syncthing. I use it on all my devices and share specific folders between devices (notes mostly) and all folders back to the server. The server then backs all that up offsite as well.
Thanks for the pointers, those will be a good reference. Now I just need to get started with a beginner how to!
I'd like to try Wayland + Sway. Do you have any recommendations for a starting config?
While this is a valid advice normally, OP has already tried this with Linux on a netbook and a dual boot chromebook. Since OP wants to do AV stuff it's probably going to be a lot better experience with a desktop (assuming more capable than laptop) and monitor(s). Going another laptop route might be fine for learning but OP wants to switch and that's not going to happen unless it's on OP's main rig.
My advice would be leave the windows installation alone and add a new drive (SSDs are pretty cheap these days) and install Linux on that. Use the BIOS to set the default drive to the new Linux drive and install and use Linux. You'll have your windows install exactly how it is when you want to go back and just pick that as the boot device from the boot menu. Making Linux the default boot drive also helps with habit forming.
I'm partial to Pop!_OS and their desktop environment.
VirtualBox is free and open source, the windows guest additions piece is not. However, they're both available for free download from the same site and they do not make any distinction between those two (at least at the time, haven't looked). They were waiting for companies to download the guest additions piece and going after them to shake down licensing fees. While I don't recall/know exactly, it seemed like they were almost exclusively going after companies they already had commercial relationships with to add more licensing fees to existing contracts. So yes, from my perspective they were shaking down customers after trying to entrap them with ambiguous free downloads. They had the legal right to do so, but it felt in bad faith.
Logseq fits the bill. By default it opens today's date journal page and I just type everything into that and tag it (you can tag at any bullet level within the note). You can also create hierarchical tags like #topic/subtopic1 #topic/subtopic2, so the note will show up for topic regardless of the subtopic.
