    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.

    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.





  • 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.




  • 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.

    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.
