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.

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.

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.

I remember your first post a year or so ago and dang you have been busy, it looks really great. I will definitely be installing this at home to organize product manuals and such.

I don’t have anything to add but I am glad someone posts this every week, I always find something new, so please keep it up :D

I know you solved it but for anyone that finds this later this feature/behavior is typically called “NAT Hairpin” in case you are looking for a setting to enable or disable, hope this helps!

I just wanted to add this video to your comment because e-ink is so cool and this guy has a bunch of macro shots of the displays that are awesome and you can see the particles in the screen changing colors.

So cool!

I found this diagram on SO at one point but I can’t find the post and it is the best explanation I have found for how all of the files work for bash and zsh, each color is an individual path of execution (eg, follow the red line).

Bottom line though, it only really matters if you are overriding something that is already defined, for example I tell my users to use zshrc and I provide defaults and common things in zprofile because zshrc is executed last when they login.

This guy’s channel is so awesome, glad to see it posted here. He has all kinds of cool tools that he built in his lab like a scanning electron microscope. His videos on atomic force microscopes and laser lithography are really fascinating as well, he is really great at explaining the concepts too, definitely recommend!

+1 for Raindrop, that app is amazing, I keep watching for a self-hosted version/alternative that is as good and they are getting closer. The killer feature for me is being able to highlight stuff and then when you visit the site again you see what you have highlighted (in addition to saving them elsewhere). I also pay for premium because it’s great, I don’t use a ton of the pro features either.

So if I understand this right you will need to change the network on the port attached to the synology in your UniFi configuration or set the vlan tag in the synology OS, I would do the former. It sounds like you just added a second network/vlan to the existing interface which means you actually created a trunk and are getting the old network untagged and the new network with vlan tags which the synology is dropping. Synology OS also doesn’t really support trunked ports through the UI (even though it does support a port that only uses a vlan tag) so it’s much easier to just leave them untagged.

This is awesome, I look forward to the weekly updates and have found lots of great tools from that. Keep up the awesome work, it is very much appreciated!

Hah now this is a great shower thought, if you want some existential dread you should watch this video from Kurzgezagt video about it called You Are Not Where You Think You Are about this idea, it’s great!

Well 5ghz requires more power, has less range, and needs its own antenna so for microcontrollers this makes it pretty pointless for devices that need range and low bandwidth for sending sensor updates, especially those that are battery powered. 5ghz can also have its own issues in cities if you have a lot of use of the DFS bands as well as being worse at traversing reinforced concrete.

Also, a 2.4ghz radio can also sometimes support other things like zigbee, BT, and BLE which can be used for other functions.

For what it’s worth, I have probably 50 WiFi devices and the majority of them are 2.4ghz sensors or switches and other low bandwidth tasks and I don’t have any issues, even when living in an apartment complex. If you are having issues you might need different hardware or more access points or something.

Anyway, all that to say that 2.4ghz definitely still has a lot of utility today.

They also make this one which uses a CM4 but you can control 4 machines! I have been eying it now that I can get CM4s again, thanks for the post!

Do you want to not use your DL380? IF no it might make a good moonlight host!
