Running into inconsistent extrusion when printing a circular model
  • 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.

  • [Solved] [Help] Should I use zram?
  • 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.

  • Shared Volumes Question
  • First will be shared files between the container in a single named volume. The others will create 2 named volumes pointing at different files with example1 from the 3rd not being on NFS.

  • SSH through VPN
  • 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.

  • Trying to understand Consent Forms, Cookies and Third-Party Vendors
  • 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.

  • [SOLVED] Any ideas what causes this in overhangs?
  • 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.

  • What we know about the xz Utils backdoor that almost infected the world
  • 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.

  • Is full caps account names not normal ?
  • 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.

  • What's going wrong with my prints?
  • 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.

  • LinkedIn vs. Library Cards
  • The reasoning is that it is not illegal to fake most student ID cards but it is a federal offense to fake or alter government issued ID documents.

    That way if it becomes an issue they can just pass it on to the authorities as their problem.

  • Ping is so mean 🥺
  • "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.

  • Should you allow username to use Apostrophe (aka quotes )
  • There are a lot of edge case characters around visually indistinguishable names. If that is a concern usernames should use a restricted known character sets instead of trying to block specific characters. You likely should also treat lookalike characters as equivalents when checking for username overlap.

  • I'll do most things

    But art is where I draw the line
