All ill say is ROS script is a huge PITA.
So, making a script that takes an object of vlan/port assignments, and running the required commands to ensure the config of the mikrotik matches the declared vlan/port assignments.

The besy way ive seen to build/manage them is to use a compile step to go from some sane declarative config in order to build the actual ROS script to make the changes.
I just havent got round to making that a thing.

I hope they are working on a native python API, so i can script in a sane language, and run it directly on the mikrotik.

Config files are easy to import/export/edit/read, tho.
It does mean you have to reset to default when you update a config file (or configure the device live, then export the config)

On a different note, i wouldnt be able to sleep with my feet sticking out.
Those douvets are so short

I guess "no" implies "this is your only chance to permanently decide".
"Remind me later" is obviously going to be an annoying reminder.
"Maybe later" or "Not now" indicates it can be changed later, but might also come with annoying reminders.

steps vs stepCount

God, this fucking API is untennable. Im out!

it only depicts the means to reach the Moon, more suitable for robotic missions that are not required to return,^[racist comment implying that robots have no right to be repatriated]^

Damnit, wrong comment

5th and 6th gen are pretty ancient.
An i3-12100 motherboard bundle is about £160, will idle with dual NVMes about 20w, and will absolutely slay a similar 5th or 6th gen low power build.

Anyway...
A Pi 4 will idle around 3 to 4 watts, and run 6 watts when the CPU is pegged. A Pi 3 is 2w idle and 3.6w pegged. (https://www.ecoenergygeek.com/raspberry-pi-power-consumption/)

Here is a low power 6th gen intel build.
https://mattgadient.com/building-a-low-power-pc-on-skylake-10-watts-idle/
Idle draw is 10w. Total pegged draw is 50w.
They mention an i7-6700t has lower TDP (35w), so that power draw under load would be probably 25-30w.
Which is still 2x higher at idle, and 5x higher under load than a raspberry pi.
Chances are the i7 would run closer to idle when tasked with work that would be stressing the pi, considering it is twice the clock speed and twice the thread count. So, maybe 2x more draw on average (6w vs 15w)?

As for costs, im seeing i7-6700t selling used for £60, new DDR4 is probably another £40, and a new cheap motherboard is £60. A quick ebay search shows refurbbed " i5 6th gens" (no model number) with 8gb of ram and 256gb ssd going for £140 (16gb of ram is £5 more, but for the sake of comparison).

I can buy a 8gb pi4 starter kit for £104 (psu, case, sd card, hdmi cable & pi4 8gb).
Which is cheaper than a refurbished i5 6th gen, and is lower power.

If i was running virtualisation, i would absolutely pay more for something i can eventually stuff 64gb (or more) ram into, as well as multigig/10gb networking.
But for running some home services in a docker compose stack? A pi4 is going to be cheaper in the short and long term.

A quick google found things like these:
https://things-embedded.com/us/edge-computers/poe-computers/

Obviously tailored more to the industrial/automation/embedded side of things with odd IO. And probably a ridiculous prolice tag.
PoE++ (802.3bt) can deliver 60w. UPoE extends this to 100w. So, there is a LOT you can power from that!

God, imagine a country going into irrevocable debt and having to actually export people.
Also, currency would fluctuate wildly as people immigrate/emmigrate.
Do you count tourists? Illegal immingrants? Legal, but not sovreign, citizens (or whatever the term is for someone working in a country on a visa)?
What if people fudge their measurements?
Does put a direct price on war, i guess.

I agree.
Pis are great for tinkering, GPIO things, or ultra low power.
Plenty of older hardware out there that is as powerful (or more so), more reliable (ie, not an sd card), and more maintainable (ie can swap CPU/ram/disks/fans/psu).
But, power consumption is always a concern. At $0.30/kwh, 10 watts is $27 per year.
So, if a pi draws 5w and an SFF draw 25w, thats $55 per year. Any price benefit of a larger/older PC is negligiable after a year or 2, so reliability probably wont come into it.

Its one reason i use DNS challenge wildcard domains.
I know security through obscurity is not security, and that a leaked wildcard cert is more damaging... However the likelihood of a leaked cert is slim, the convenience is huge, the attack window isn't huge (well, 90 days) and less published information about internals feels more secure.
