It looks like underextrusion at speed. It might be a clog or you might want to try a higher hotend temperature. PLA can have inconsistent ideal temperatures even with the same brand due to different colors and additives between batches and 185 is on the low side.

Yep, YouTube even has an A/B testing tool for automating this.

It can often improve performance and memory latency and usually only has a minor CPU performance impact as it trades cycles waiting for memory for cycles decompressing memory. It is usually decent even on low power embedded devices.

There are a few edge cases where ZRam is not great. If your data is already compressed or encrypted copying it around in memory is much more expensive. It’s also harder to tell exactly how much data can be loaded into the “free” memory. It’s also a bit slower for serialized memory access in large data sets if the compression ratio is low.

Right image, but under those each one below would also be wearing large pants covering each side of the subtree.

It depends on how the router responds to other non-forwarded ports. For UDP an open port with no response is the same as a dropped packet. A scanner will only know if the device sends an ICMP response back to indicate that it is closed.

It’s not well explained for sure but judging by the names of the cookies I bet those store the consent (opt in/out) values for the other tracking options. Another way of putting it would be those are functional cookies related to the cookie consent form itself so that you don’t have to re-select consent options every time you visit the site.

I’m not an electrician so I don’t know if it would be up to code (very likely is not) but you might be able to use a current sensing relay to trigger the lights. For safety I would add a local disconnect as well.

If it isn’t showing up in lspci then it isn’t currently attached to a PCI port. lspci will show all devices with or without a driver, known and unknown. You can try lsusb to see if it is attached internally to USB (very uncommon). It might also have a firmware level power saving disconnect feature that needs to be either disabled or managed by the OS in some way. It might also be showing up as a different device than you expect (also very uncommon) most cards will show as either Ethernet controller: or Network controller:.

Make and model of the laptop and any identification details from the ethernet device under windows would be helpful for diagnosis.
