Oh it is certainly not just you, I am sometimes confused reading them even for commands I have used for years and I know what flag I am looking for but don’t remember the exact syntax or something hah! I am glad they are there but they are definitely not a complete guide to any command, especially built-ins.
Interestingly, this is something AI has been very useful for to me, less searching because I can describe the outcome I want and it figures out what I am talking about generally.
Okay so the disks aren’t also on UPS? That might actually be even worse than the whole thing getting turned off, ZFS is definitely not meant to be run on removable disks like that.
Okay so when you say “unplug the power” do you mean shut it down first or just pull the plug? The latter is a great way to corrupt your storage pools as ZFS uses memory for read and write cache etc by default. You definitely need to do a graceful shutdown especially if there is data that was recently written to disk, that’s why a UPS is so recommended. That said you can usually import an existing pool when that happens, I think there is a UI menu for it now.
As others have said, be careful with fans if they are large, many of the plugs don’t have a very high wattage rating and are all definitely rated for 15a at max usually, you might consider a smart relay instead (like a Shelly or something).
That said I have switches and plug-in and in-wall relays from Aqara (zigbee) and TP-Link (WiFi) and zooz (zwave) and all are fine and do the job. Not all support power monitoring if that is something that matters to you, it’s not a universal feature.
Have you tried adding 239.255.255.250/32 to your outbound subnets variable? This is the multicast address for SSDP which mDNS ultimately relies on if I remember right, I recall having to do this for Plex in the past.
In addition to what others have said there is an interesting video from Veratasium about that NIST department, they have a wild variety of items.
Just to make sure, all of your links need to be in quotes if they are not. The : in a url can make some yaml parsers think that it is another block, there are other URL safe characters in general that are special characters in yaml so it’s a good idea to put them in quotes.
This is a cool idea! This sounds a lot like what DANTE and AES67 or AVB are used for in pro audio (mixing console sends multichannel and outputs can subscribe to one or more channels), maybe they have some ideas on timing sync which I think would be the hardest part as others have said, it is crazy how small of a jitter your brain can hear.
Hey not sure if I’m too late but there are a few places I have run across that I don’t see mentioned:
Also, your resume sounds a lot like mine, I have done a wide variety of things over the years. If you want someone to review your resume I am happy to, send me a DM or something. I’m not a developer but I have reviewed a lot of resumes for people and mentored all kinds of engineers, I am a principal level engineer in a related path though.
In case anyone here doesn’t follow it, Ivan’s YouTube channel is awesome, he has been working on a crazy marble clock: https://youtu.be/K3FMVmAte3g
ProperPrinting is also great, he has some cool videos on custom extruders and printers he designed and a wild extruding resin printer with UV lasers.
