A lot of technology people like to share the devices and programs they use. I'm no exception, and I like to spread the word about great technology, so here is a list of some software I recommend you to use.
Syncthing is a thing that syncs your files. Better yet, it requires no central server. I have it running on my computer, my phone, a school computer I worked on, and a server, although you don't need it. Syncthing syncs by folder. An example setup would be syncing pictures to your computer: you could mark "Send only" on your phone and "Recieve only" and "Ignore delete" (an advanced setting) on your computer to make it so that once your pictures are synced, you can safely delete them from your phone without them disappearing from your computer. It runs as a background service, so you don't ever have to press a "Sync" button; it all happens automatically.
KeePass is a password "keeper." KeePass runs entirely locally via a .kdbx file. It is locked with a master password or a key file if you want one. It has TOTP support, which means you can use it as "Google Authenticator" for two-factor authentication. It is best used with Syncthing to sync passwords between devices, such as my phone and computer.
Mastodon and the Fediverse
I'll have a separate article on this later, but it's definitely worth checking out. No ads, no tracking, and it's not lacking in any good features.
I have Fedilab on my phone, use the website on my computer, and run Pleroma as the server. You can follow me at @[email protected] (try https://social.b252.gq/users/blake in the search bar, might work better).
