Server as heating device - how do I do this?

So I have this silly idea/longterm project of wanting to run a server on renewables on my farm. And I would like to reuse the heat generated by the server, for example to heat a grow room, or simply my house. How much heat does a server produce, and where would you consider it best applied? Has anyone built such a thing?

Servers are 100% efficient at heating, but heat pumps are 300% efficient. Get the most energy efficient devices you can, and heat your house with a proper heat pump.

If they did this to me I would immediately drag my locked up cart to the customer service desk and return everything. Hard no. Not buying my groceries from a place that aspires to be a prison.

I wouldn’t put a lot of trust in Telegram. Not only is their cryptography off by default, it’s a bespoke hand-rolled non-standard algorithm that might not work as well as they say. Oh, and it’s been potentially backdoored by the FSB (Russia’s CIA) for six years.

It’s crazy how the US gov basically handed him a monopoly on EV charging infrastructure, something Rockefeller could have only dreamed of, and the guy throws it away less than two weeks later in some ketamine fuelled stupor. Then has to backtrack at the cost of reputation, confidence, and sentiment. Truly another great stable genius.

We need to break up the grocery conglomerates. Nowhere else in the world is the food system so heavily monopolized and vertically integrated. Go tell an American about Cara Foods/Recipe Unltd[1] — they won’t believe you!

Right? I’ve been using NextCloud/OwnCloud since ~2015. It’s a very standard LAMP app, nothing fancy going on at all. Give it enough memory and you’ll never have any problems, same as any other web service.

600 metres below the countryside

It’s to be stored in bedrock more than half a kilometre down, sealed in an impermeable polymer.

It’s not perfect, but it’s a hell of a lot better than oil/gas which store their waste in your lungs.

I did it back in 2020 when we all had nothing better to do. Got as far as installing X11 and Openbox, and halfway through setting up the toolchain for Firefox.

It was fun - the kind of fun digging a big hole is. It’s not for everybody, but I sort of enjoyed it.

My wife and I have been spitefully avoiding loblaws for a while now. We get most of our meat & produce from the weekend market, bread from the local bakery, and anything else from the Asian/Indian supermarket or Metro if it can’t be found elsewhere.

The last straw was the prison gates and the receipt checking. Show some dignity.

It depends. I’d say on average it’s higher for “convenience” items but the cost of milk, cheese, rice, pantry staples, etc seems to be about the same.

If there was a food basics nearby I’d probably go there, but in my city that means driving another 15 minutes.

Wow, you mean tying our entire nation’s success to a speculative real estate market was a bad idea?

A huge majority of politicians are landlords. They’re more represented than mining, tech, forestry, oil, agriculture, or any other big industry lobby group.

Rents will rise, but it’s by design.

So basically the “conventional” generation methods use a Big Thing spinning at a specific speed to generate AC power. Solar and wind spit out DC which has to be converted to AC and also synchronize to the rest of the grid.

Hydroelectric, nuclear, coal, methane, all use a big-ass turbine at exactly 60.00 Hz to supply the grid. This is fairly easy to sync, since a change to load or supply will slightly change the physical rotation of the generators. If the load increases, it will draw down the speed of the turbines as it pulls on it harder. When the load is more than the generators can supply, or changes too quickly, it can cause a breaker to flip to prevent damage to the equipment.

With DC generators, the inverter connected to the grid works differently. It has to sense the frequency changes and react based on “external” factors. Right now there aren’t really widespread protocols to signal this type of grid conditions to solar/wind farms, so they have to be a bit more careful and preemptively disconnect to prevent damaging the inverters.

So it’s an entirely solvable problem. It just requires the industry (and ERCOT) to be proactive…

A decent solution is to install shairport-sync on the Pi and advertise the service over multicast dns (Apple bonjour protocol). This effectively creates an AirPlay device on the network that’s usable from any iDevice. This had a very high “wife approval factor” when I did something similar at home.

As long as there’s no consequences for this kind of Pinkerton shit, it’s only going to get worse.

There’s usually a fuse under the dash labelled with “DCM” or “MAYDAY” or “MCU” or something like that. If you pull that fuse out, it’ll cut the power to the transmitter unit (4G/5G module) and kill all of this creepy shit at the source.

It’s unlikely but not impossible. I’ve been using PM with a custom domain for about five years now, and never thought too hard about leaving.

In an ideal world, a company like ProtonMail would be cooperatively owned by the workers and paying users, sort of like a credit union.

Pragmatically, they’ve done fine stewardship of the service for the last decade or so they’ve been around. A big part of it is that their value proposition depends on stability and trust. But it could be better.

The bastards can never take away your shell script full of arcane and unreadable curl commands parsed by incomprehensible awk scripts!

They had a chance to re-route the CN & CP lines around the city 50 years ago, but did nothing because it meant the city was on the hook for the environmental remediation. I wouldn’t hold my breath for anything to change.

In my opinion it points to a more dangerous thing, “continuous delivery” software mindset seeping into safety critical systems.

It’s fine, good even, that web developers can push updates to “prod” in minutes. But imagine if some dork could push largely untested control system updates to your car’s ECU… it’s one thing for a website site to get a couple errors, but it’s a very bad thing if it makes your steering wheel stop working.

Unfinished products make more money, and it’s high time a consumer protection law clamped down on this.

Anybody who’s ever exposed any service to the internet knows this as the “background radiation” of the net. My boxes get thousands of random connection attempts per day. The best practice for years has been to use keypairs and/or VPNs. Friends don’t let friends expose RDP to the web.

Pearson was always a garbage airport, but it’s gotten so much worse since 2020. I hope the workers get all they demand and more.

Going to go against the grain a little here and say, why bother? If you already have a background in Linux, that will get you further in your career much faster. My education was 100% windows/cisco, but I haven’t touched either in the better part of a decade since I’ve been working with mostly “web stuff” where Linux dominates.

Invest the time you would spend slogging through learning Active Directory and grinding MCSE into something useful like Docker, ansible, bash, infra-as-code, etc. It’s more fun, and it’ll make you way more money!!

I guess this is the next chapter in the endless middle-east war. The British & French got exactly what they wanted when they drew up those borders. It’s truly tragic how many people are going to die in the next decade because of religious and nationalistic despots and their egos.
