Mass produced to be as cheap as possible, vs carefully built and engineered to last as long as possible.

Fatmap. It was freemium, but now it's moving into Strava, who knows how much of it they'll hide behind subscriptions.

There's so many great FOSS maps, but I haven't seen any that give you the 3D view that Fatmap does. It's essentially Google Earth with overlays of routes for various activities.

  • USB PD can negotiate pushing up to 240W now at 48V, which is a fair bit.

So if I wanted to wire my home to take advantage of this, supposing I had a house battery on solar, would I have some kind of DC-DC converter from battery to 48V, then cable to outlets with some kind of USB PD adaptor? How much advantage do I get from this, vs using existing 240V outlets + wall wart?

My exposure to Linux is pretty minimal, especially Linux with a GUI, so forgive my ignorance. Even reading over this thread I'm confused as to the issue here.

I don't need an ELI5, but maybe someone can explain it like I don't know what Wayland is?

My understanding is that an app should ask the system to display an object at X size, let's say text at size 14. The system then works out that at the currently selected display resolution, size 14 will be Y pixels big. If needed, the system can scale that based on user preferences- a small, high DPI screen could render size 14 at only a couple of millimetres, for example.

Is the problem that devs are building things in a way that bypasses scaling? For example, hardcoding size 14 text to be Z pixels high?

Hardware should lead. It's easier to upgrade the software to make the hardware work, then it is to upgrade the hardware when the software decides to support it.

Just because I don't really know the geography there, I thought I'd look it up. Sticker range on the cybertruck is apparently 500km, which (as the crow flies) would get you from Moscow to Kursk, or from Kursk to Kyiv.

The Adventure Zone is good for the same reason as Dimension 20. A lot of DnD 'actual play' podcasts are people who play a great game of DnD, but don't make a great podcast.

TAZ is a bunch of comedy podcasters who decided to play DnD for a goof, and it works. The first arc has a rough first couple episodes, but it turns into one of my most beloved pieces of media across any format.

I stopped using my MacBook Air after 9 years. I did a battery swap at some point, and I think I replaced the charger after the cable frayed. Best windows machine I ever ran.

I've witnessed a lot of talk about this song- I love me a good cover- and this is the first time I've read this quote. Thanks for that, it gives some great context.

It's pretty niche. I'd be interested in it as a device for messaging between folks who are out of mobile range - think farmers, hikers, mountain climbers, forestry workers, fire service, etc.

Plenty of type I come out sideways- they are lower profile than most I've seen, slightly more so than type G.

This can actually be a bit of an annoyance, sometimes... If the socket is right next to the floor, or in a densely packed area, for example, it can make plugging difficult.

And if it does have a ground pin, it's mandated that the ground be longer than the power pins, for exactly the reason you mentioned about G,D,M.

The recessed feature of F I do like, even if it makes the plugs physically larger than they need to be.

Ok, so when I'm next driving through a Swiss tunnel, and suddenly the tunnel twists inside itself infinitely, I can blame FreeCAD.

 

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.
