using an old 1st generation iPad
How to install apps - from
https://apple.stackexchange.com/questions/135060/how-to-install-apps-which-require-a-newer-version-of-ios-on-a-1st-gen-ipad
1. On your old iPhone/iPad, go to Settings -> Store -> set Apps to Off.
2. Go onto your computer (it doesn't matter if it's a PC or a Mac) and open the iTunes app. Then go to the iTunes store and download all the apps you want to be on your iPad/iPhone.
3. If the iTunes on the computer and your iPad are both signed into the same Apple ID, and the iPad is connected to the internet, then go on your iPad/iPhone to App Store -> Purchased -> tap on an individual app you want to install.
4. You'll get a message that says "The current version requires iOS 6.1 or later, but you can download the last compatible version," just hit Download.
This method should at least allow you to have most apps on your outdated device. Most of them will work, but sometimes even once you have the app installed on your it still won't run correctly. That's just tough luck. But in my experience that's not too common; apps usually work just fine.
How to get ebooks on the ipad:
1. Using Amazon Kindle Store and Kindle App
2. Using direct links to pdfs, or email attachments - when opened in safari, they show a "Open in" button on the top. You can open pdf and epub in Freading, mobi in Kindle.
3. Using gutenberg.org

converting csv files in google drive to google sheets
This stackoverflow answer seems to be good. Either download and re-upload after enabling "convert uploads" in Drive settings, or use an Apps script.

signing out of google account on Android
This link has the details for Android 5.0+
On Android 5.0+, Settings -> Accounts -> Google -> Choose the account you wish to sign out of -> Menu with 3 dots on top right -> Remove account
On the LG Q6 running Android 8.1, there is a search field in settings where I can enter Accounts, and directly get listings of the Google accounts. Clicking on an account brings up a page with Remove account also listed.

New Google sites has support for custom urls with HTTPS
Looks like New Google Sites automatically provisions SSL certs after domain validation, but the cert takes 24 hours or so.
