The problem about the “automatically adjust resolution and bitrate” can be done in two ways:
Using a GPU to transcode the 4k video in real time (generally unavailable on VPS)
Encoding the video in multiple resolutions and bitrates, using much more disk space
Both solutions are expensive on a VPS.
In this case when I need to share stuff in 4k 60 (basically never) I just host on YouTube unlisted and having Google foot the bill. Maybe think like this: the content really deserves to be 4k 60 fps? Home videos that I share with my family are downgraded to 720p as anyway they will watch it horizontal on a vertical screen
I use technitium but it’s like pihole, designed for a few concurrent users in a local network? Instead you want that anyone in the world can use your DNS?
But you would only attract bad actors, normal users won’t use a random DNS server as it could redirect specific sites to phishing pages
About the root problem, as of now new installs are trying to let the user to run everything as a limited user. And the program is ran as root inside the container so in order to escape from it the attacker would need a double zero day exploit (one for doing rce in the container, one to escape the container)
The alternative to “don’t really know what’s in the image” usually is: “just download this Easy minified and incomprehensible trustmeimtotallynotavirus.sh script and run it as root”. Requires much more trust than a container that you can delete with no traces in literally seconds
If the program that you want to run requires python modules or node modules then it will make much more mess on the system than a container.
Downgrading to a previous version (or a beta preview) of the app you’re running due to bugs it’s trivial, you just change a tag and launch it again. Doing this on bare metal requires to be a terminal guru
Finally, migrating to a new fresh server is just docker compose down, then rsync to new server, and then docker compose up -d. And not praying to ten different gods because after three years you forgot how did you install the app in bare metal like that.
Docker is perfect for common people like us self hosting at home, the professionals at work use kubernetes
Purchase the domain with cloudflare, for email it depends how you use it:
With an email client like thunderbird:
A cheap service like mxroute is perfect
If you need to use a webmail:
You need to pay a lot because the free webmails are all unusable for advanced use.
Good options:
Zoho at $1 per user per month
Exchange with ovh at €3 per user per month
Bad options:
Google workspace at $10 per month per user plus the blood rights for your firstborn and pray that they don’t alter the deal
proton pro at $9 per user per month but IMHO is extremely overrated for what they offer at their price point (unless you need end to end encryption when emailing other proton users)
I just unsubscribe when it becomes too prominent. There was a guy doing a recap of the news of the day in 5 minutes. Suddenly added 2 minutes of ads. Fuck that
They’re not doing like proton and close basic stuff like IMAP and SMTP as a way to force you on the official apps
I especially love the feature where you can bounce emails based on domains, keywords or TLDs. My spam folder is finally empty. IMHO bounce back spam is much better, as the spammers get a response that the address is invalid and hopefully stop wasting their limited computing resources on that address.
Zoho is not open source, but proton is a “fake” open source that is mostly used for marketing: they opened only the UI, which communicates with a proprietary protocol to a proprietary server - useless. They also reject or ignore any pull request on GitHub.
I much prefer doing ocr by myself if really needed, than getting an half assed “book” full of typos and broken tables just because someone did an automated OCR but didn’t have the 5-6 hours required to manually edit to make it decent
Already be thankful that someone took the time to flip page by page in their scanner manually and upload it somewhere
