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'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.

As someone who also has produced code that looks like random characters spewed onto a terminal while using fpdf, I feel this one.

It can still have issues with potential attacks that would redirect your client to a system outside of the VPN. It would prevent MitM but not complete replacement.

IIRC the PS3 had it's firmware encryption key published not the source code.

Your experience may depend on which distro you use and how you install things. If you use a distro with a stable upgrade path such as Debian and stick to system packages there should be almost no issues with upgrades. If you use external installers or install from source you may experience issues depending on how the installer works.

For anything complex these days I'd recommend going with containers that way the application and the OS can be upgraded independently. It also makes producing a working copy of your production system for testing a trivial task.

I had that very device right about 2002. Put my whole CD collection on a few mp3 disks. Replaced it a few years later with a 6GB mp3 player.

It's very likely that your disk is failing.

dd if=/path/to/file.mkv of=/new/file/path.mkv conv=noerror,sync bs=4k

Should give you a file with just the damaged bits missing.

PTSD from the days long ago when X11 error log would fill up the disk when certain applications were used.
