I have mine from all my grades from primary to high school. My father wrote an analysis on the back of one after the term had ended and what I could have done for the grades to be better: basically to make tiny little improvements consistently throughout the year. I have come a long way but I still try to follow it.

Since no one has commented, let me be the first to say that the photo you shared looks really cool!

I have that exact same setup but with 4 TB disks on zfs in mirrored mode. Have not noticed any performance issues in my home lab setup mainly being used for immich and media serving. I had purposely chosen disks of different brands specifically for this reason. My vote goes to this setup.

What I'm looking for is a way to take backup of Docker containers so I can restore them in case things go wrong. Doing so with VMs is so easy. If nothing works, I'll make an image of my OS disk. Unless some benevolent self hoster tells me a simple way, which was my hope when posting here :D

Last year I wanted to set up a budget media PC and got enamored by this video: https://www.youtube.com/watch?v=WCDmHljsinY

I got a 600 G3 with the 4560 processor, installed Debian onto it and hooked it to my 4k TV mainly to run immich and stremio.

Immich runs just fine, though I have gotten too fast behind its upgrades and having less knowledge about Docker, I'm afraid to update immich. Need to figure that out.

But what disappointed me was that my good quality videos (even the downloaded ones) are choppy to run (unlike the fluid expectations from the video above) and I don't really know what I should look into to make it better.

There are also Sn (Stannous) for Tin, Pb (Plumbum) for Lead, Fe (Ferrum) for Iron, Hg (Hydrargyrum) for Mercury, Au (Aurum) for Gold and Ag (Argentum) for Silver.

Thank you so very much! This makes sense and answers my question perfectly.

I have a question for you that I've not been able to get answer to by normal googling or asking the GPTs.

I need to focus light from cinema projectors using camera lenses. As you might be aware, projectors may use lamp or LED as their primary light source. The former used more wattage for producing same lumens of light.

My question is: if I choose two projectors of each type that give out same lumens of light and I focus all of it with my lens, will one of them heat up my lens more than the other? I'm other words I'm just talking about the heat perception of light of equal intensity from the two sources and not how much heat is generated in creating them, if that makes any sense.

Thanks!

There exist maps derived from satellite images called Land Use Land Cover maps that categorise each pixel into predefined classes like built up, forest, water, roads etc. Granted that these days semantic segmentation is used to generate such maps but traditional image processing and digitization has always been used traditionally. There is no AI involved in using them for the purpose I mentioned though. Gaming engines like unity have built in tools as well as add-ons like Gaia that have cool procedural generation features. Using such maps in conjunction could help in creating realistic and familiar worlds and this blender tool gives me much hope.

I would like it to be possible to give some hints to the model by providing maps showing where roads, buildings, vegetation should be and let it work its magic. Maybe take it further by procedurally generating buildings based on their footprints and building type, like hospitals , schools etc, as identified in maps. That way we can have racing sims in the roads we are familiar with. And much more...

Is it capable of recognising disks set up as zfs mirrors? I have my OS on 256GB SSD while I have two large disks where I keep my data set up as zfs mirrors. I am not very well conversant with docker so everytime I need to do a critical update, I simply create a disk image of my OS drive onto the zfs mirror. Currently, i do it by booting into a live Ubuntu USB and running commands to make it recognise the zfs mirror before cloning the OS disk. If rescuezilla can do it by default, I will prefer it over live Ubuntu.

Those have a modern use too. I keep my power bank in the bag and use it to charge my phone on the go.

 

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 just watched Apollo 10 1/2, a Jack Black narrated story of how it was like living as a child, in Houston when the moon mission was in full swing.

I found it intriguing and set me thinking: most movies exaggerate/glamorise things around their stories. Maybe they have to, to make the movies interesting.

But what are some movies that, kind of, provide a, kind of, window peep into a place/time. An 'authentic' representation of it, as close to how you saw/experienced it? Maybe you could expand it to include the travel documentaries/vlogs too because I find that most of them choose only the highlights of a place and look away from the mundane.

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?

 

Hello Blender Wizards!

I am seeking your help in trying to solve a GIS problem using Blender. Any help, pointers or general discussion related to this will be highly appreciated.

I am a Blender n00b but I am aware that Blender has a GIS plugin that helps in creating cityscapes by capturing terrain, buildings etc. from GIS maps. Suppose a city with 3D buildings, parks, lakes has been created. Now, I need to find all dwelling units from which a particular park/lake is visible.

GIS has something called a viewshed analysis which can be used to find area which will be visible from any given point. But that is the limitation, it just gives the view from a point, not a whole area.

My idea is to create stack dwelling units (apartments in high rises) as white objects having unique Object IDs in Blender and parks/lakes as colored light sources. Upon rendering, it is easy to see what dwelling units are lit up in which color. That is all good for visual analysis.

My question is, is there any way in Blender to get Object IDs of Objects that have non-white colors on their face? Or do I have to take the help of a Gaming Engine for this?

Looking forward to the responses. Cheers!

 

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.
