I encountered something I don't quite understand, and I was hoping someone could enlighten me.

I set up Tailscale on my router with subnets, so I could remotely access my home network. This worked great. Then, at home, I was happily browsing the internet on my main PC, and decided to dial into another machine on my network. It couldn't access it at all. Disconnecting Tailscale on my main PC restored lconnectivity.

I don't understand what is happening here- the only thing I can think of is that my internet traffic was being routed through Tailscale, but I don't have an exit node.

TL,DR: home PC sees Internet but not LAN when connected to Tailscale, why and how fix?

I've not been playing with my online gaming group for a few months, but when I was, I was playing a sentient gelatinous cube, who's just the happiest and friendliest thing ever. Last night I was able to rejoin, and we managed to pull off a great surprise. The PCs were led into a trap, and suddenly all sorts of oozes and jellies started appearing. The DM did a great description of an ominous, looming gelatinous cube approaching, and one side started to form into a face... Which oozed into a mouth and said.... Which is when I popped into the call and laid on the familiar happy, friendly voice and said a hearty hello and nice to see everyone again! Perfect timing, great build-up, everyone loved it. Such a great theatrical moment.

I've got a few projects on the list which will be battery powered. I'm thinking of using 18650s just because of how ubiquitous they are, but I know there's other options out there. Are they worth it?

• E-ink calendar
• Solder fume extractor
• Lora station
• Portable "trail camera"
• Home assistant remote controls Etc etc etc

Vague title I know, but I'm enough of a beginner at this to not really know what I need to ask!

I would like to rent a server, that allows me to spin up different services, including things like Windows to use as a remote desktop. Ideally, I would then be able to just migrate this whole setup to my home server.

I thought it would be as easy as renting a scalable VPS, but apparently if you run something like Proxmox on those, you'll get terrible performance?

My understanding is that I'd need to rent a bare metal server, but then my 'scalability' will suffer- I can't just wind up and down the specs as needed, correct?

My user case: For the next several months, I'm on the road, without a proper computer. I may have some work doing some CAD drafting, hence Windows. I'd also like to have some containers to run some dev tools, databases, web hosting. I'd also like to use the same service to start building my future home server environment- nextcloud, *arr, etc. Once I'm back home, I'd like to easily migrate this setup to a local machine, then continue to use the server as my own cloud and public entry point. And further down the line, hosting a gaming server for friends. In terms of location, Sydney would be great.

Will a VPS do this? Or do I need bare metal? Is there a single service that will allow me to do both, with one billing? Or am I doing a Dunning-Kruger?

Thanks in advance for your hints.

I'm looking at a permanent install of a Windows machine that runs a few digital signs. I want to achieve remote access and file upload to the Windows box, as well as accessing the internal web server of the displays on the same LAN. This LAN will be attached to a corporate network, but I would prefer if it did not have access to the internet. I'll have to work with the IT department to get this happening, of course, but I'm hoping to go in prepped with potential solutions. Could anyone tell me if these ideas will work, or what I'm missing?

• VPN tunnel. This would be whichever VPN that their IT supports. Would I be able to simply install the client on the windows box and my machine, and then on my machine connect to the VPN, use TeamViewer in LAN mode for control of the Windows box, and web browser for control of displays? I'm assuming their IT would set up the upstream switch to only pass that VPN connection, so that the Windows box does not see the internet, and I cannot see their internal network.
• Some kind of IPMI/PiKVM solution- This would be a second computer, attached to the corporate network, but not to the signage LAN. It would just be a KVM for the Windows box. I would then dial into that via its webserver, and control the Windows machine. The control for the displays would be accessed via browser on the Windows machine. I like this solution, as it keeps the networks separate, but I think that uploading files will be a challenge.
• Or is there a better way?

Hi! Hopefully this is a good place to ask. I've been googling around a fair bit, but haven't had much luck- I'm either finding ELI5 type articles, or in depth tutorials on setting up a model to tell the difference between a frog and a dog. I'm not sure if those are relevant to my concept.

I would like to implement a ML algorithm to detect a particular type of defect on a production line. Our current camera system isn't quite up to the task, but gives good, consistent imagery, and I have a good historical dataset. The product moves past the camera, it snaps a single black and white image, then the product moves on. This means that most of my images are more or less the same. These defects are obvious to the human eye.

Could someone please give me, a noob, a bird's eye view of how I would go about using ML to create a model for this? There's so many choices of tools and tutorials that I don't know which would be best suited to this use case.
