Oh, okay. Not sure if you want an explanation, but it’s here if you want!

The kernel is kind of the part of the operating system that glues everything together. It provides common interfaces for accessing hardware, provides a library of useful functions to programs, and manages running all of your programs at the same time (like, you know how you can have more programs running than you have CPU cores? The kernel is responsible for scheduling when each program gets to execute instructions on the CPU and stuff).

A binary blob is just what we call it when some piece of software (in this case a driver), is only available in the executable binary format. No source code available, so it’s effectively a black box unless you make a substantial effort to reverse engineer it.

An API is an “application programming interface” which is more or less just a library of functions to do stuff. So if the interface for graphics drivers to talk to the kernel changes or something the old binary version of the driver may not work with newer kernel, and because it’s a binary blob nobody can update it except Nvidia.

Other people have mentioned it a bit, but a huge thing in my opinion is just support for newer kernels. I held on to a GTX 570 for a looong time because it worked just fine for everything I wanted to play, but I was kind of upset because 1) it never got the Vulkan support Nvidia promised at one point, and 2) eventually the Nvidia binary blob driver stopped supporting it, and eventually the old binary blob no longer ran on newer kernels due to changing APIs. Open source drivers make it a lot easier for somebody to support the hardware if they care about it enough for a very long time. This is one of the main reasons why I kind of refuse to buy an Nvidia GPU now. I just wish GPGPU support was better on AMD platforms (though this seems to be improving?)

Running Jellyfin off of a VPS provider seems needlessly expensive. I guess server hardware has an upfront cost, but having real hardware to host it on at home will be far more cost effective long term, especially for storage.

Mine always have the ReplyTo field set to the email of the senior security analyst, so I always say hi and tell them that maybe the higher ups need some training on how to not send sketchy as fuck emails that train people to click on phishing links.

Yeah, that’s my main concern. I believe the Immich developers have said they have no desire to implement it, though… Which is fair enough, it doesn’t work for my desired use case though.

I want all data to be encrypted before it even reaches the server. Yes, I don’t want to trust even my own server for my image backups :), particularly since I would want to use something like Immich to provide photo backups for friends and family and I don’t even want to technically have access to their unencrypted photos unless they explicitly share them. I kind of want the attack surface for my photos to be as small as practical too. It’s almost certainly worse to have them available on my device unencrypted than a dedicated server, but it’s worse to have them unencrypted on both (and I want photos available on device so, thems the breaks).

I get that a lot of people won’t care about this and that they’d rather be able to run the image recognition features of Immich on the server and stuff, but I don’t think it’s entirely unreasonable to want encryption for this. If nothing else I’d love to be able to back up photos for friends and family and legitimately be able to tell them that it’s encrypted and I can’t see any of it. It’d be even sweeter if they could do image recognition on device and sync that metadata (encrypted) to the server as well.

I’m kind of disappointed by the lack of encryption. It sounds great, but I don’t want to trust the server.

I guess it depends how much of a frequency shift you do, but I imagine with the blanking intervals it will mostly just sound like a nasty sawtooth wave?

For what it’s worth I also haven’t had any problems. Maybe we’re just lucky, though.

Yeah. You’ll probably have access to a calculator these days, but that doesn’t mean it’s not worth knowing some basic arithmetic. Playing around with arithmetic is a good way to gain an understanding of the fundamentals and have a better sense of what the operations mean and how they work, which helps even when you do have a calculator.

Seems like it might be fine: https://nextcloud.com/blog/nextclouds-push-notifications-for-ios-and-android/

I wouldn’t do it. Not worth the risk.

For what it’s worth, this has not been my experience after self hosting my email for nearly a decade. It has not been a constant battle at all… it has just worked, and I get responses whenever mailing random people all the time and have not had delivery issues to my knowledge. That said, I have talked to people who have had issues and every time there has been something wrong with their configuration (usually DKIM or rDNS is not set up properly). There’s enough that can go wrong that I wouldn’t recommend people send important emails with it unless they’ve been doing it for a while and they’re sure it’s working, but in my experience this is all fear mongering. Self hosting your email is very doable and is generally not a constant battle against getting put in the spam slammer. There’s a lot of picky little things to set up at first, but once it’s set up it’s usually fine.

In my experience the problems with self hosting email mostly occur when something is misconfigured. I think it’s good for people to try to self host it, and if you pull it off it’s great (I love having mine self hosted, and it’s convenient to be able to have as many email addresses, storage, and accounts as I want). It is difficult to get right and debug when something is going wrong, but it’s far from impossible. If you set up SPF, DKIM, and DMARC and have rDNS pointing to your mail server’s domain name you’ll likely find success. It’s possible I’ve just gotten lucky, but I have never had a problem with IP ranges getting banned.

Tunnel broker blocks port 25 by default, but you can ask nicely and they’ll open it for you. It’s a good option if you don’t have an IPv6 address otherwise.

Having an IPv6 only mail server is potentially risky, though… some other mail servers may only talk IPv4.

I’ve had good luck on a couple of cheap providers. I think a lot of them block port 25 by default, unless you ask, which maybe gives you a better chance. Plus DKIM and stuff are starting to help. There’s probably always some stupid mail server that will block huge swaths of IPv4 if somebody farts in the neighborhood, but I think the situation is improving.

In my experience self hosting email it has pretty much been “set it and forget it”. I feel like there’s a lot of fud from people with misconfigured email servers (because there is a lot that can go wrong on setup). In every case I’ve seen where people are complaining about email deliverability I’ve found that they haven’t configured DKIM or rDNS properly. That doesn’t mean there can’t be issues, and I am sure it is technically possible to get sent to oblivion, but I feel like this issue might be somewhat overblown.

Smart TVs are god awful, and I hate the OS on our LG TV. That said there is finally a Jellyfin app on WebOS so it has that going for it now… I’m too cheap to buy a separate box for Jellyfin and stuff for the TV, so I guess it’s good enough… but in general I wish the TV OS got out of the way a little more.

The human genome one was the one that stood out to me. I’d be curious to see a source from the time if you’ve got one!
