They have an Android tablet of their own that I've configuredb strictly for child use and it has helped them learn many things easily using apps such as Khan Academy Kids and Duolingo Kids. There is precious little beyond that that is not not infested with ads or needs subscriptions that are bound to cost a lot in the long run.

I have an old machine with Debian connected to my TV that I can also attach a PS3 controller to, if needed. What software can I explore in the Debian world that can help my child continue her learning journey. I'm open to suggestions not just for learning tools, but also for games that might help.

PS: they get plenty of outside time too, so that's not a worry. I just want them to explore things and discover things they might like. I'm amazed by their ability of assimilate stuff so any help about diverse things like gamified music theory, art, logic will be highly appreciated.

Cheers!

I have self hosted immich on Debian on my homelab. I have also setup tailscale to be able to access it outside my home.

Sometime ago, I was able to purchase a domain of my choice from GoDaddy. While I am used to hosting stuff on Linux, I've never exposed it for access publicly. I want to do that now.

Is it something I can do within tailscale or do I need to setup something like cloudflare? What should I be searching for to learn and implement? What precautions to take? I would like to keep the tailscale thing too.

PS: I would like to host immich as a subdomain like photos.mydomain.com.

Thanks!

I have set up a refurbished PC as a media PC with storage. The OS, Debian, is on an m.2 nvme disk of 256 GB. I have connected 2x4TB risks in zfs mirror mode to store my media.

Off late, while booting, I've noticed some messages that suggest that the health of nvme disk is not good. Searching the error, i realised that I should not rely on it. I've done a number of tweaks to set up my system the way I like that I want to save by creating an image of the OS drive on a fresh nvme disk of same size that I have.

How do I go about doing it? I could boot using a live USB and create the image on the HDDs but the live USB OS won't recognise my zfs, right? Is using another external disk or another PC my only option here?

Thanks and cheers!

PS: The machine is a HP Elitedesk 800 G3 that has a wifi port that I've heard can be used as additional port for m.2 drives. Is it true?

I'm planning to construct a home sometime in the near future in hot, arid part of the country. Obviously, keeping the home cool is a major concern and I've been considering all available options.

One of the recurrent ideas discussed online is using geothermal cooling. But I think I don't have enough land to implement it. I have a related idea though.

Water supplied during set hours of the day by the municipality is fairly cool even during the summer months and it is a common practice around here to first let it collect in an underground tank and then pump it to the overhead tank as needed.

What if I create a closed loop system of circulating water with two car radiators: one in the underground tank, submerged in cool water and another in the living area of the home with a fan blowing behind it.

Do you think it'll cause perceptible change in room temperature if there is, say, a temperature difference of 10 degrees Celsius between water and ambiance? I intend it to only reduce the load on the air conditioners and/or just delay the use of AC.

What kind of math/physics will be needed to assess if this is a feasibility? I tried looking hard but could not find anyone else discussing this idea, so I'm reaching out to you guys.

Thank you for your time.
