Look at the PDF carefully before sharing it. Most academic publishers put a timestamp on it that reveals who downloaded it, at least at institution level. Sometimes this is even embedded as metadata. If the PDF says anywhere “author personal copy”, please don’t share it on the author’s behalf.
This is mostly to avoid getting them into trouble.
Otherwise, go and share, authors love it!
Here is a possible case study for you. https://OpenRouter.ai.
They are doing what you think of doing, for the various LLM APIs. Three reasons why they offer added value:
I use it. It’s more lightweight than AdGuard, in terms of resources. I find the UI to be at the same time a worse UX but quicker to achieve things. I don’t think that they perform differently once they have the same blocklists.
How could one be invited to their email service? I don’t think I know anyone who’s in there.
Your requirement for a mobile iOS app makes it harder so I’ll go non-free software with my suggestion: Tap Forms. Offline first, iCloud sync, macOS and iOS apps. But no Android or Windows apps.
If you wanna keep it self-hosted, these services need an internet connection anyway, even Airtable. Just go with a Web based one that has good mobile layout.
If you have an offsite copy of your files (and not in a sync service like Dropbox) you are already in a better position than most.
Restoring from offsite takes time, even with Backblaze’s option of shipping a hard disk. You may also have data corruption troubles, companies may close all of sudden. It’s just not as convenient as local copies.
A further copy that is locally available is simply a better strategy. Adding more copies after these two is not a bad idea but you start getting hit by the law of diminishing returns.
You can actually read more about the 3-2-1 rule in a Backblaze post: https://www.backblaze.com/blog/the-3-2-1-backup-strategy/
Technitium that I host myself. Works like a charm.
In case nginx does not work out for you, you can opt for more generic reverse proxies. frp is my favorite one: https://github.com/fatedier/frp
Same, I would actually be curious to listen to a right wing tech podcast as the two concepts clash so hard in my brain.
I have self-hosted my own emails many times. Up to having three SMTP servers with failsafe option at DNS.
It’s super nice, but I would never self-host SMTP again. It’s a nightmare. I had to email or open a ticket at most ISPs despite my clean IPs. Most ISPs simply blacklist all IPs unless they are major email providers already.
My advice is go for it but let SMTP be handled by who will deal with these frustrations. MXroute is a great choice and it’s cheap.
I use https://github.com/bastienwirtz/homer because it is dead simple to configure, and I protect it with HTTP auth at the reverse proxy level.
There are some managed tunnel alternatives but they are not cheap. At this point it’s cheaper to rent a $20/year VPS and install one of these: https://github.com/anderspitman/awesome-tunneling
I personally love frp
Edit: I have never tried it, but there’s also Tailscale Funnel https://tailscale.com/kb/1223/tailscale-funnel/
