The Honeynet Project, related to the SANS Institute when I last checked, has a lot of resources on honeypots that are worth a look, if you haven't already.

That's a really open-ended question. Depends purely upon your interests and appetite for risk, etc.

Might be worth looking at, from a Docker perspective:

• AdGuard Home (I think it's better than Pi-Hole)
• Wireguard or similar. Great for reaching your services when away from home.
• Audiobookshelf. Audiobooks. There are good apps.
• Calibre-Web. Ebooks.
• RSS feed reader, for non-social media websites you visit. Plenty to choose from: FreshRSS, TT-RSS, Sismics, etc.
• Gitlab CE. If you're a developer or can otherwise make use of version control.
• Gotify. Alerting on your containers. Has a good mobile app.
• Heimdall. A dashboard for everything you're running.
• Komga. If you're into manga. The best iOS app is meh, but the best Android app is awesome.
• Mealie. Recipe database.
• Paperless-ngx. Excellent for storing your PDFs and other digital life.
• PhotoPrism. Basically Google Photos.
• Portainer. Great for managing Docker containers/stacks.
• qBitTorrent. Guess what that's for.
• SWAG with Authelia. SWAG does reverse proxying with a Let's Encrypt certificate, and automatically renews it for you. Authelia provides MFA (Authy, Google Authenticator, etc) on top of it.
• Vikunja. Todoist or Toodledoo without having to pay for features.
• Wallabag. Basically Pocket.
• Watchtower. Automatically updates containers for you. Can exclude the ones you don't want to update, etc.
• Webtrees. Family tree research, if that's your thing.
• YouTransfer. Useful for sharing files without having to use Dropbox, etc.

I have in the past run a Valheim server and a VRising server, too. FWIW.

Every time a social media site has offered, pleaded, cajoled or forced me to take a non-chronological timeline, I've refused. And if that refusal eventually becomes impossible (no option, addons no longer work, etc), I take my eyeballs elsewhere.

You're not an edge case. :)

I used Linuxserver's Docker container of Dokuwiki when I migrated my notes from Evernote a few years ago. It was easy to setup and configure, has a number of plugins that further improve it, and it did the job really well.

I ended up migrating it all to Obsidian this year, as it serves my needs better, but otherwise I'd still be using Dokuwiki.

I migrated away from Evernote a few years ago, where I kept my "paperless life" (PDFs of receipts, bills, etc) and general notes (work, study, etc). Opting to self-host most of the things I can, I moved the notes to Dokuwiki and the rest to what is now Paperless-ngx.

This year I realised that Obsidian suits my needs better than a wiki, so migrated the notes to that. If it's just for your stuff, I'd recommend the same. (Though if you collaborate with anyone, I've heard Notion is a better option specifically for that.) Obsidian has a lot of extensibility, which will steepen the learning curve, but it's worth it.

I sync Obsidian's Vault using my Synology NAS's "Drive" client, and Obsidian works perfectly with Windows, Mac, Linux, and Android. The only shortcoming is iOS (because iOS), though I believe you can work around it using Obsidian Sync or at least one other tool I've seen mentioned. It might also be possible via the Obsidian Git extension, but I've not tried it with iOS and requires (from a self-hosting perspective) that you have a local Git server (for example).

It's a good question. A vault is only as strong as the credentials required to access it.

Bitwarden does have MFA support, though. If you're using it without that enabled, you're asking for trouble.

FWIW, I have an LG LED smart TV (2xHDMI, 1xDVB-S2, WiFi, NIC, etc) and it's only been connected to my network once, for a post-purchase firmware update through my AdGuard Home. WiFi and Ethernet is disabled, and I use it with my Nvidia ShieldTV (Plex*, Netflix, ChromeCast, etc).

I won't let it go online as I expect it already phones home if you let it, and don't imagine LG will be able to resist ad injection into content, like Samsung and others do. So it's an excellent quality dumb TV, which meets my needs perfectly.

*Plex Media Server runs on my NAS. The Shield and my mobile devices are Plex clients.

Exposed is the right term. Other than my Wireguard VPN port, everything I have exposed is HTTPS behind Authelia MFA and SWAG.

I'm tempted to switch Wireguard for Tailscale, as the level of logging with WG has always bothered me. Maybe one day.

When my old NetGear ReadyNAS Duo (2 bays, SPARC, 100Mb NIC) was reaching its EOL I looked into a purpose built server, a mini of some kind (NUC, etc), or a standard QNAP or Synology NAS. Eventually settled on a Synology DS 920+ (4 bays, x86_64, 1Gb NIC).

It's been rock solid and amazing value for the 2.5 years I've had it. It's running the majority of my Docker containers, Plex Media Server, a Linux VM, and a few other things. It also has its own shell/CLI, which is useful. I don't use Synology's "phone home"/remote access stuff, but Synology Drive and Synology Photos are great - they provide the equivalents of Dropbox and Google Photos respectively, and it works across Windows, Linux, Mac, iOS, and Android (via VPN when outside the house). No regrets at all.

I've had gitlab/gitlab-ce running on my NAS for 6+ months and it's been reliable, mostly as a central repository and off-device backup. It has CI/CD and other capabilities (gitlab/gitlab-runner, etc), but I've not implemented them.

TT-RSS is fantastic, providing you hold your nose and wear as asbestos suit if you ever dare ask a question or raise a valid issue. The dev is... well, I'm not a fan. I won't use it out of principle.

FreshRSS is a good-looking and skinnable alternative with a good Docker image, but I had issues with the inability to flush old items. Has a decent web UI.

These days I'm using Sismics and the web UI.

This last sentence is the crux of the matter. People don't like change, but quickly forget that they spent time learning the site that they're so familiar with.
