Everyone's doing these app defaults lists lately. Since they're lists and I happen to like lists, I guess I'll chime in, even though I don't think these blog posts add much value for others. Instead, they could be interesting to look back to for myself in a far future? Here goes.

• Backup system: Restic synced to the NAS with my own system-tray wrapper.
• Bookmarks and Read It Later systems: I paste links that interest me into Alfred that has a workflow to Obsidian. To be honest, most interesting stuff is just jotted down on paper. I have almost no "read it later" backlog.
• Browser: Firefox.
• Calendar and contacts: Self-hosted Radicale CalDAV/CardDAV.
• Chat: Signal with literally four people willing to do so, everything else's still WhatsApp.
• Cloud File Storage: lol, good one.
• Coding environment: For light and quick scripting, Sublime Text. Otherwise, any of the dedicated tools from the JetBrains folks.
• Image editor: ImageMagick and occasionally GIMP.
• Mail: Apple Mail for macOS for brainbaking---hosted by Mailbox.org after being fed up with ProtonMail---and unfortunately Microsoft Outlook for work. I don't want to mix these, and the latter is an Exchange server. I don't have a mail client on my smartphone and neither should you.
• Music: Self-hosted Navidrome + Substreamer Android app.
• News: I try to avoid these but out of boredom regularly fail to do so.
• Notes: Primarily fountain pen and paper---this includes todo lists---mixed with digital notes in Obsidian.
• Password Management: KeePassXC.
• Photo Management: Self-hosted PhotoPrism, although we have difficulties finding stuff once the photos are poured into this system. I'd like something even simpler.
• Podcasts: I just press play in the browser? Subscribing goes via RSS.
• Presentations: Hugo + RevealJS.
• RSS: NetNewsWire.
• Shopping Lists: What's wrong with recycling a piece of paper?
• Spreadsheets: For student grading, Google Sheets or Excel if I have to share it with colleagues.
• Text Editor: I'm typing this Markdown post in Sublime Text.
• Word Processing: lol, another good one. For my writing, I use Markdown + Pandoc + LaTeX.

Conclusion: I have a preference for simple analog and self-hosted tools.
