Hosting service- Netlify. It's free, fast, and easy--just push changes to your site's files to GitHub to update the site.
Hardware- running with an Intel i7-7600U @ 2.90 GHz, 32 GB ram, and a 500 GB SSD on Windows, which is really nice and allows me to pretty much not care about how many programs or tabs I have open.
Blog management- I just maintain a Python file I wrote that can push forward updates to the head,header, and footer elements and generate new pages from Markdown files.
Password management- I use LastPass. For my Google, LastPass, and other most sensitive accounts, I use a passphrase created from rolling dice and looking up words in a word bank. I also use Yubikey or Authy Authenticator on most important sites when they offer it.
Notes- Google Keep. I've tried Evernote and a few others. IMO, they still all suck, but Google's is the simplest that gets the job done for me. I use Standard Notes when I want extra security.
Email- I use Gmail for everyday stuff and Protonmail when I want max security.
VPN- They've been under fire lately for basically just moving who can spy on you from your Internet Service Provider to some rando company. That said, I trust ProtonVPN and F-Secure over most ISPs anyday.
Phone- Pixel 3a XL. Probably the best phone you can get for under $650.
