When you say your talk talk hub is bottlenecky, what does that mean? Are speeds slower that your service contract? Are those speedtests over wifi or LAN? Also which hub do you have? I ask because this site does have good things to say about the newer talk talk hub.
For your questions though:
The modem with authenticates with the ISP and then has ethernet ports to plug into. Some modems have built in wifi which will let you get away with just one device assuming your dwelling is within the wifi coverage. If a modem doesnt have built in wifi then you'd need a router for wireless access.
A separate modem + router will generally have better features on the router, but typically cost more money and may be overkill depending on what you need
I noticed in that article i linked it said that some talk talk hubs have a pass through mode. So if the issue is just the wifi access then you could get away with just getting a router (keeping your current hub).
Expired domains first can be bought by registrars and then they might sell or auction it off. For instance godaddy will scoop up a lot of domains and auction them off even if it was registered somewhere else first. And unfortunately a surname.tld probably will invite domain squatters to try to get it and then charge much more for it
You can look into something like dropcatch which they will try to get the domain for you before another registrar gets it. Look into their backorder service and just check the timing to make sure they still can try to get it.
Regularly check the whois info (via icann lookup) to see which registrar currently has it which can help you determine if it has gone to an auction.
Who needs access to these private repos? There's always raw git (has a web server if needed). That's what I've been doing since moving to codeberg for my public projects and eventually i might set up a private forgejo server.
Sourcehut also offers public, private, and unlisted repos
Giscus / utteranc.es use github discussions/ issues to do comments so that might be an option
For one of my projects i setup remark42 which does allow anonymous comments. You can also set it up to allow logging in to a few different platforms. 7 months and no issues.
Isso is another one i had looked at which can do comments without an acct
Edit- to add i haven't found arch's limit, it feels like i am bound only by my own limit in my time, ability, and willingness to tinker with my setup. arch itself is widely supported, it has many official packages through pacman, and then additional through the "arch user repository" (AUR) so chances are most of the things you want or need have a package that can be installed with an AUR helper (like yay/paru which install from both pacman and AUR). In other distros you get more of a one-size fits all and you lose some of that ability to change things whereas arch you're giving a minimal setup and left to build the system to your liking. It does take more time and expertise than other distros but it does give you more control. For me the trade off was an easy decision, but it's not something i blanket recommend to everyone.
Tflops is a generic measurement, not actual utilization, and not specific to a given type of workload. Not all workloads saturate gpu utilization equally and ai models will depend on cuda/tensor. the gen/count of your cores will be better optimized for AI workloads and better able to utilize those tflops for your task. and yes, amd uses rocm which i didn't feel i needed to specify since its a given (and years behind cuda capabilities). The point is that these things are not equal and there are major differences here alone.
I mentioned memory type since the cards you listed use different versions ( hbm vs gddr) so you can't just compare the capacity alone and expect equal performance.
And again for your specific use case of this large MoE model you'd need to solve the gpu-to-gpu communication issue (ensuring both connections + sufficient speed without getting bottlenecked)
I think you're going to need to do actual analysis of the specific set up youre proposing. Good luck
The table you're referencing leaves out CUDA/ tensor cores (count+gen) which is a big part of the gpus, and also not factoring in type of memory. From the comments it looks like you want to use a large MoE model. You aren't going to be able to just stack raw power and expect to be able to run this without major deterioration of performance if it runs at all.
Don't forget your MoE model needs all-to-all communication for expert routing
Custom DNS servers specified on the device to circumvent the pihole
dns over https or tls
hotspot from approved device
alternative YouTube front ends
These are just off the top of my head. Best case scenario the blocking does work and the teen never tries to bypass it. They'll still just move onto "wasting" time on something else. This is treating the symptom and not the root cause.
Pihole can set up "groups" for different blocklists. You specify client by IP or MAC address so it doesnt matter what the dhcp server is, so long as there's a static IP or static MAC address. My pihole server doesn't have dhcp set up and I'm able to do this fine
Though from personal experience this just becomes a game of cat and mouse, and if you have a motivated teenager then they will find a way to circumvent this. For example android can rotate MAC addresses, and IP addresses are trivial to spoof as well.
Haven't used all of those but my recommendation would be to just start trying them. Start small, get a feel for it and expand usage or try a different backup solution. You should be able to do automatic backups for any of them either directly or setting up your own timer/cron jobs (which is how i do it with rsync).
I submitted a response but if i may give some feedback, the second portion brings up:
I am willing to pay a substantial amount for hardware required for self-hosting.
This seemed out of place because there were no other value related questions (iirc). Such as:
I believe self hosting saves me money in the short term
i believe self hosting saves me money in the long run
I'm sure you could also think of more. But i think it's pretty important because between cloud service providers and any non-free apps you want to use, it can be quite costly compared to the cost of some hardware and time it takes to set things up.
The rest of my responses don't change but if you're wanting to understand the impact of money in all of this, i think some more questions are needed
I switched January this year.
