Huh, that's interesting. I would have thought that a TV running Linux would be called 'smart'.

I'm with you though, it's better to be more 'modular' and have your playback device- be it PlayStation, media server, heck even television receiver, seperate from the display itself.

I've been pondering a gear cutter setup. This is usually done with a mill and a rotary table, but I was thinking of something simpler.

The blank would sit on a rotating table, that spins about the Z axis. The shaft for the cutter sits parallel to the Y axis, and moves along the X axis to contact the blank.

The chest strap?

If they do, at least you'll now know they're a shitty bike shop and you don't want to be friends with them anyway!

They probably won't, though.

Bookmarked for later.

25mm to 38mm is a pretty big jump. Do you have photos of the part of the frame where the tire is now? With a caliper measurement for scale?

Keep in mind you want some clearance- if the gap is say 40mm, you'll have 1mm of clearance both sides which is not enough. As far as I know, there's no hard and fast rule, but roughly 5mm each side seems to be a rule of thumb minimum.

Take it into your local bike shop. You'll pay a little more for the tyre than if you purchased online, but you'll have advice, different ones to try, and someone to do the hard work for you, with nicer tools. Plus you'll make a good contact and help put food on a local table.

For what it's worth, I run 32mm on my gravel bike, and that's seen some shit. You'd be fine with under 38mm for rail trails (and more).

5 axis and 5 dimensions are essentially the same thing, right? A 2D graph has 2 axes, a 3D one has three, 4D graph can be shown with colour representing the 4th axis, etc.

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.

It came right up to the gas storage facility- I bet they worked pretty hard to stop that particular candle from lighting up.

Is there a sub that is less focused on interesting data, and more focused on data presented beautifully?

Neon Genesis Evangelion. The 'angels' are the baddies that arrive to fuck up humanity.

It's an absolute classic. Go watch it.

 

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.
