Another person mentioned Ubuntu if coming from Mac. I haven’t considered it before but they’re probably right.
I was using Mac at home, but Windows at work. So moving to Mint was easy.
Ubuntu was OK on high performance hardware but when they introduced snaps nothing worked so I moved to Mint.

It works as a phone. It works for documents, contacts, calendars etc. Bluetooth keyboard and mouse work, as does a USBC dock (but no DP).
I like it a lot.
The Telegram and Matrix channels have been great for people sharing tips like this.
I love it.
No DP Alt mode.
Like the rest of the world?
Australia car license limit: 4500kg for C (Car) class [0]

United Kingdom car license limit: 3500kg or 8250kg for class B [2]
France limit: 4250kg towing for class B [3]
Cavet: the above weights can be a vehicle or a combination vehicle weight depending on a bunch or intricate rules.

I hope that the decommissioning of this kind of solar farm is better managed thant the likes of the Northern Endeavour FPSO, where Woodside offloaded it to a small company to dodge the decommissioning costs of the field, leaving the taxpayer to foot the bill[1].

The reactive component has significant impact on the generation equipment and grids. It also causes the Ferranti effect, where the voltage along the cable rises. This can make managing the voltage within the cable difficult because at no load, the load end has a higher voltage than the source, and when loaded, the middle of the cable has a higher voltage than both ends.
During stable operation these effects can be managed with Statcoms, shunt reactors and voltage regulation tap changers. However during transient operation you will be relying upon the static protective devices such as surge arrestors, depending on how large the transient is.
DC transmission does not suffer from the same reactive power component and has less losses, but it does require large convertor stations at both ends.
Both are and will be required skills for the foreseeable future (next 200 years or so).
Knowing how to grow food and maintain a healthy environment is becoming a lost skill. “Grounding” has science now saying it’s a good thing for your blood, heart and brain (don’t have link on hand but when connected to ground scientists have found blood physically changes and can be seen in microscope).
Electricians are usually a licensed trade. This makes it more protected but also makes you more useful.
You can branch into engineering later if you wish, and you usually make for a better engineer cause you know a 630mm^2 cable doesn’t fit in a 20mm gland.
Substation automation based on IEC61850 is everywhere and more common. It consists of servers, gateways, IEDs (which also need programming), Ethernet, VLANS, switches etc. so you get a technology knowledge base you can relate to other areas of yours, or your friends and families life.
You can also learn to program SCL files using python or other such tools. Get bored of big power? Switch over to instrument and controls.
There will always be a need for plants, food and power. Why not set yourself up for success those ways?
(Oh! And you get paid to train when you’re an apprentice and you don’t end up with student debt or university fees)
For example, in Australia, many hardware stores sell “Grid Connect” devices. This is a cloud solution for the likes of Arlec. However, most of these devices can be flashed with Tasmota. This removes the cloud and keeps everything in house using MQTT. Security is WPA2 and TLS. I run my IOT devices on a separate VLAN and use 2.4Ghz network as it seems to have more coverage and is more reliable.
Here is a list of >2000 devices which can take the Tasmota firmware:
My pick for a bright daylight would be about 6000K colour temp and I’d just throw some fittings in a room then walk outside at mid day to determine how many watts Id need to satisfy.
Bonus of these is you can get coloured lamps with more awesomer colours than LEDs.BLV is one manufacturer.
Second bonus is if you use a grow lamp in your setup, it’ll also help reduce the effects of SAD. They use the same fittings.
Oh, and remember diffusion is the key for comfortable indoor use.

I would has a guess that 16ms is the physical limit for most consumer hardware (and maybe commercial computing) to detect mains loss.
Of course there is industrial hardware that can detect quicker than this but it would add a LOT of cost for arguably little gain, or something that could be solved in another manner.
I guess features like that depend on developers available time and the size of the communities too. My assumption would be the ProtonDB service would have a much larger audience than OpenWRT does, hence the efforts put into the quality of the data.
> Um guys, maybe remove devices without wifi support from the “supported devices” list to make the list an actually useful resource?
Open WRT relies on members of the community to help keep the documentation up to date. You can edit the table of hardware here [1].
I wouldn’t say it’s unsupported hardware though. Some people use these devices as a router and don’t need wifi enabled. In this case I would say it is supported, but in limited functionality.

The article linked in another reply (https://toronto.ctvnews.ca/ontario-recommends-pfizer-covid-1...) for Canada suggested they stopped the Moderna Vaccines at a rate of 1 in 28000.
I wonder, what rates determine when action is taken?

Like many things, people wanted cheaper and they wanted it now. I refer to this [1] excellent website to explain the economics of purchasing equipment or services, buying your first or last oven or for use in project management decision making.

If you receive a shock, if can affect the rhythm of your heart and cause problems later. We’re taught to go and get an ECG after receiving a shock. Like jump in the car and go to the doctor or hospital and have someone else drive you. If you’ve received a shock - go get checked out.
