It honestly sounds more like someone convincing you that crypto is great than someone convincing you that Greenpeace is great.

NAT sort of accidentally includes what is called a “stateful firewall”. It blocks inbound connections because it doesn’t know where they should go. IPv6 eliminates the need for NAT but doesn’t prevent stateful firewalls. It is just as easy to implement stateful firewalls (actually a bit easier) for IPv6 without NAT. The difference is that the choice is yours, rather than being a technical limitation.

For example if I had a smart microwave I would want to ensure that there is some sort of firewall (or more likely for me not connect it to the internet at all, but I digress). However I may want my gaming computer to be directly accessible so that my friends can connect to my game without going through some third-party relay, or maybe my voice chat can be direct between me and my friends for extra privacy and better latency.

Also relying on network-level protection like this is a good idea in general. Eventually a friend is going to come over with an infected network and connect to your WiFi. With just NAT this will allow the malware on their computer to access your microwave as they are “inside the NAT”. If you were applying a proper stateful firewall you would likely apply it to all traffic, not just internet traffic.

Mostly dropping the analogy as it falls apart quickly once you try to talk about more specific details.

How do I handle whether I want my phone number to be known to the world?

If you don’t want people to be able to call you then you can block incoming calls. This is sort of the like IPv4 NAT case, people can’t connect in (unless you forward ports). Or if you want to you can allow incoming calls. The choice is up to you now rather than being forced by a technical limitation.

Does my phone number ever change on its own or can I freely change it?

Generally you will be provided a “prefix” by your ISP. In v4 this would typically be a full address. In v6 there are a huge number of addresses inside this prefix. In both cases how often the prefix chances is up to your ISP, but for v6 you can chance the suffix you use inside of the prefix as often as you want.

Who has the phone book?

There are two main parts of “the phone book”. There is “Who owns this address?” and “How do I get to this address?” Both of these are basically identical between IPv4 and IPv6.

For “Who owns this address?” there is a global directory of assignments. This is typically done in multiple layers.

1. The whole address space is split among reserved addresses and continental registries.
2. The continental registries distribute addresses to organizations or individuals.
3. The organizations and individuals distribute addresses to customers/devices.
4. This may continue, for example if your home internet connection is assigned multiple addresses (rare on v4, expected on v6) then you can assign addresses to devices in your house.

For “Who do I get to this address?” A protocol called BGP is used to advertise where an address is available from. So I may say “If you want to get to addresses 32 to 64 come talk to me”. This is sort of like in a hotel how there are signs saying which room numbers are in which direction. When two networks are connected they share this information between them to establish a “routing table”, so they know how to get to everywhere else on the internet.

This may look something like this:

1. Your laptop wants to talk to address 17. It has learned that addresses 1-8 are “local”, everything else goes out your home internet connection.
2. Your residential ISP is connected to 4 different other networks (likely a Tier 1 ISP), two of these have access to address 17, but one is “closer” so your ISP sends it there.
3. This tier 1 ISP knows that a network it is connected to serves addresses 16-32. (Maybe this is your friend’s residential ISP.) So it sends the traffic there.
4. Your friends residential ISP knows that addresses 16-20 are assigned to your friends house, so it sends the traffic there.
5. Your friends router knows that address 17 is their desktop, so it sends the traffic there.

Overall no single places knows how to get to every other address. But they know the best next step. So you don’t know where 17 is, but you know to send it to your ISP, your ISP doesn’t know where 17 is but knows that their partner tier 1 ISP knows how to get there, the tier 1 ISP doesn’t know where 17 is, but knows that it belongs to your friend’s ISP, your friends ISP doesn’t know what device 17 is, but knows that it is in your friends house, then finally your friends home router actually knows that 17 is your friends desktop.

You can sort of imagine this like delivering mail. If I send mail in Canada that is addressed to England, Canada Post doesn’t really care where exactly I am sending the letter. It just knows that it needs to forward it to Royal Mail and they will handle it from there.

I switched to Immich recently and am very happy.

1. Immich’s face detection is much better, very rarely fails. Especially for non-white faces. But even for white faces PhotoPrisim regularly needed me reviewing the unmatched faces. I also needed to really turn up the “what is a face” threshold because otherwise it would miss a ton of clear faces. (Then it only missed some, but also has tons of false positives). On the other hand Immich just works.
2. Immich’s UI is much nicer overall. Lots of small affordances. For example the menu item to “view in timeline” is worth switching alone. Also good riddance to PhotoPrism’s persistent and buggy selection. Someone must have worked really hard on implementing this but it was really just a bad idea.
3. Immich has an app with uploading, and it allows you to view local and uploaded photos in one interface which is a huge UX win. I couldn’t find a good Android app for uploading to photoprism. You could set up import delays and stuff but you would still regularly get partially uploaded files imported and have to clean it up manually.
4. Immich’s search by content is much better. For example searching for “cat with red and yellow ball” was useless on PhotoPrism, but I found tons of the results I was looking for on Immich.

The bad:

1. There is currently a terrible jank in the Immich app which makes videos unusable and everything painful. Apparently this is due to some Album sync process running in the main thread. They are working on it. I can’t fathom how a few hundred albums causes this much lag but 🤷 There is also even worse lag on the location view page, but at least that is just one page.
2. The Immich app has a lot less features than the website. But the website works very well on mobile so even just using the website (and the app for uploading) is better than PhotoPrism here. The fundamentals are good but it just needs more work.
3. I liked PhotoPrism’s advanced filters. They were very limited but at least they were there.
4. Not being able to sort search results by date is a huge usability issue. I often know roughly when the photo I want to find was taken and being able to order by date would be hugely helpful.
5. You have to eagerly transcode all videos. There is no way to clean up old transcodes and re-transcode on the fly. To be fair the PhotoPrism story also wasn’t great because you had to wait for the full video to be transcoded before starting, leading to a huge delay for videos more than a few seconds, but at least I could save a few hundred gigs of disk space.

Honestly a lot of stuff in PhotoPrism feels like one developer has a weird workflow and they optimized it for that. Most of them are counter to what I actually want to do (like automatic title and description generation, or the review stuff, or auto quality rating). Immich is very clearly inspired by Google Photos and takes a lot of things directly from it, but that matches my use case way better. (I was pretty happy with Google Photos until they started refusing to give access to the originals.)

Most Intel GPUs are great at transcoding. Reliable, widely supported and quite a bit of transcoding power for very little electrical power.

I think the main thing I would check is what formats are supported. If the other GPU can support newer formats like AV1 it may be worth it (if you want to store your videos in these more efficient formats or you have clients who can consume these formats and will appreciate the reduced bandwidth).

But overall I would say if you aren’t having any problems no need to bother. The onboard graphics are simple and efficient.

is framework agnostic

But it isn’t, because they depend on framer-motion and React. JSX is, but the icons aren’t.

You can trivially provide on-hover animations using CSS in SVG then your icons are framework agnostic. Not to mention smaller to download and more efficient to execute.

There are three parts to the whole push system.

1. A push protocol. You get a URL and post a message to it. That message is E2EE and gets delivered to the application.
2. A way to acquire that URL.
3. A way to respond to those notifications.

My point is that 1 is the core and already available across devices including over Google’s push notification system and making custom push servers is very easy. It would make sense to keep that interface, but provide alternatives to 2 and 3. This way browsers can use the JS API for 2 and 3, but other apps can use a different API. The push server and the app server can remain identical across browsers, apps and anything else. This provides compatibility with the currently reigning system, the ability to provide tiny shims for people who don’t want to self host and still maintains the option to fully self host as desired.

Must be because Factorio released 2.0 and the Space Age DLC recently.

IMHO UnifiedPush is just a poor re-implementation of WebPush which is an open and distributed standard that supports (and in the browser requires, so support is universal) E2EE.

UnifiedPush would be better as a framework for WebPush providers and a client API. But use the same protocol and backends as WebPush (as how to get a WebPush endpoint is defined as a JS API in browsers, would would need to be adapted).

Why are these TypeScript + JSX rather than just SVGs? It seems that the paths are defined as SVG but they are using some JavaScript framework to define the animations rather than just using SVG or CSS animations.

Why WASM? It seems to me that the attack surface of WASM is negligible compared to JavaScript (and IIUC disabling JavaScript will also disable WASM).

Third-party frames is definitely a good way to reduce your attack surface though. Ad embeds are often used to distribute exploits.

A few hundred a month is just a few per day. That is pretty low volume by most standards.

I would say in general if the SMTP server could be replaced by a single human writing and mailing snail-mail letters by hand it qualifies as low volume.

Ah ok. You aren’t doing auth. I don’t understand how this is relevant.

Are you doing auth in the reverse proxy for Jellyfin? Do you use Chromecast or any non-web interface? If so I’m very interested how you got it to work.

The concern is that it would be nice if the UNIX users and LDAP is automatically in sync and managed from a version controlled source. I guess the answer is just build up a static LDAP database from my existing configs. It would be nice to have one authoritative system on the server but I guess as long as they are both built from one source of truth it shouldn’t be an issue.

Yes, LDAP is a general tool. But many applications that I am interested in using it for user information. That is what I want to use it for. I’m not really interested in storing other data.

I think you are sort of missing the goal of the question. I have a bunch of self-hosted services like Jellyfin, qBittorrent, PhotoPrism, Metabase … I want to avoid having to configure users in each one individually. I am considering LDAP because it is supported by many of these services. I’m not concerned about synchronizing UNIX users, I already have that solved. (If I need to move those to LDAP as well that can be considered, but isn’t a goal).

I do use a reverse proxy but for various reasons you can’t just block off some apps. For example if you want to play Jellyfin on a Chromecast or similar, or PhotoPrism if you want to use sharing links. Unfortunately these systems are designed around the built-in auth and you can’t just slap a proxy in front.

I do use nginx with basic with in front of services where I can. I trust nginx much more than 10 different services with varying quality levels. But unfortunately not all services play well.

Even then how you you know? I don’t think anyone can reliably look at a vegetable and tell you how nutritious it is. I don’t think it is reasonable to have the general population being experts in evaluating vegetables.

I think what could work here is mandated labeling. This is required for most foods but generally not produce. I think there are some reasonable reasons for this, but for farms producing huge volumes it seems that occasional testing that gets reported at the store would make sense.

How are you configuring this? I checked for Jellyfin and their are third-party plugins which don’t look too mature, but none of them seem to work with apps. qBittorrent doesn’t support much (actually I may be able to put reverse-proxy auth in front… I’ll look into that) and Metabase locks SSO behind a premium subscription.

IDK why but it does seem that LDAP is much more widely supported. Or am I missing some method to make it work

But it does boil down to business pressures. The business prefers more and bigger produce to more nutritional produce.

Is that a bad thing? Maybe not. Maybe you can just eat more to get your nutrition since higher yield should reduce cost.

But the point still stands that there is very little business pressure to make a nutritious product.
