InkScape and LightBurn

Unable to Perform Path Operations

If you can’t do boolean operations in InkScape, you may have to un-group the paths. It can’t do path operations on groups, and sometimes InkScape will put a single object into a group. You can combine paths and do boolean operations on them that way, but that is using the path combine tool, you just cannot use the grouping feature.

LightBurn Limitations

You can’t use object operations on it for LightBurn to understand it. No use of object clip or mask should be used when creating files for use in LightBurn. You can make use of path difference or intersection to make changes to similar effect when avoiding the object tools.

Joplin Failed to Fetch Due to Certificate Expiration

Recently I ran into an error when trying to update Joplin (hooked up to WebDAV on NextCloud).

Last error: FetchError: request to failed, reason: certificate has expired

I checked the SSL cert with FireFox and everything looked good there. Finally I decided to try updating the application, on a wild attempt to fix it in a simple way, and… it worked. It might have just needed a reboot, but the update worked in this case.

The VLANs Strike Back

I recently re-did my entire network, changing out switch locations, what ports were plugged into where, and so on. This wasn’t too bad, except I didn’t make note of one thing: which ports were VLAN tagged. This became quite the struggle as I tried to figure out why my WiFi couldn’t access the internet, and why all my servers were inaccessible. I even changed what port the Unifi AP was plugged into to try and kick that VLAN possibility out of the running. Little did I know that BOTH ports I tried to plug the AP into were tagged, so neither could reach the internet. I ended up plugging my RT-N16 back into the modem to see that I had internet, and then moved the switch port the access point was into one more time to find a port that wasn’t tagged. Once I had that, I swapped what port my servers were plugged into to find a non-tagged port, that would get my Unifi controller back up so I could go and clean up the rest and get things back into an operational state.

TLDR: Label or remove VLANs before re-architecting things
