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.

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 35° (or something close to it) is the slicer setting for overhang detection it likely changes the cooling/speed/flow settings. If that is the case you can set it to a lower detection value and maybe get better results or change the normal cooling/speed/flow to be closer so it isn’t as drastic of a change.

From what I’ve read is not authentication bypass, it’s a RCE using certificates to deliver the payload. If a specific signature is found it runs the code that was sent in place of the signing public key. It also means that only someone who has the ability to generate that specific key signature could use the RCE.

There were some other bits that looked like they could have been placed to enable compromising other build systems in the future when they checked for xz support.

If filesystem UUIDs are IP equivalents. Then device paths are MAC addresses. FS labels are DNS. Device mapper entries are service discovery.

Business systems from the 80s used to automatically convert everything name related to caps. It made it easier to do string matching which was generally case sensitive in the DB. It also made data entry easier as you just turn capslock on and type.

No so much formal as lazy semi-formal.

The biggest issue is that your corners are lifting from the bed during the print. Fixing this is usually a combination of making sure the bed is clean and adding a brim to increase adhesion. Maybe messing with temperature and cooling fan settings for the first few layers.

Second is things look a bit over extruded. This could just be due to the corner issue though so fix that before any other changes.

“Invalid” or “unparseable” are more understandable descriptors in normal language. I don’t think I ever heard of garbage/junk being used for that in language theory but it may be domain specific usage.

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.

Likely you needed to include the intermediate cert chain. Let’s encrypt sets that up automatically so it’s quite a bit easier to get right.

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

You might also try running a few leveling probes in a row to check the repeatability of the measurements. It’s possible that something is messing with the ability to make good measurements (unstable power feed, heat warp, probe binding, etc).

Initrd contains the systemd binary and enough libraries, services, and kernel modules to get booted this far. The system failed at switch root which is where the real root disk is mounted. Initrd can contain as much or as little as needed to get a working system which can be a lot of you are using a network filesystem as a root for instance.

You may want to try hotter too if you haven’t yet. Printing faster can sometimes require a bit of extra heat and too low can cause a different kind of stringing.

The expression syntax for the GNU find command is very powerful. I would expect that it is up to the task. If you don’t have the GNU find command with it’s extensions I could see how it’s would be difficult.

If you want an automated system that can protect against ransomware your backups need to be hosted in some way where the backup server has control of the retention and not the client (NAS, local disk, etc are not sufficient). If your NAS supports automated snapshots that can’t be deleted by the backup user it can mostly fill this gap but may need to be checked for how it handles snapshots when the disk fills.

For self-hosted solutions I’ve used BURP, Amanda, and Borg backup in the past but have switched to Proxmox backup server as my VMs all run in Proxmox. You still need to consider full disaster recovery scenarios where both your primary and backup system fail. For this PBS sports both tape and remote server replication.

There are also many cloud solutions that do this automatically. For cloud I would always use them in tandem with some kind of local backup.

For all of these they should have an admin account that has strong protection and doesn’t share credentials with any of the primary systems.
