Come on, let's admit it fellow HNers... Most of us are jealous/envious of this network setup and would love to have the money and time needed in order to own something similar. Extra points for powering all these from solar panels and also for all the "little" gizmos (ADB, NTP, LoRa, TinyPilot, MQTT and temp/humidity/power monitoring). @monstermunch You're living the dream :-)

And not a single mention of the noise level in this room. Those rack servers get insanely loud.

I had a single SuperMicro in the basement one summer and it had to go after a month or so. You could hear it everywhere.

I find your comment to be at the absolute peak of sanctimony. Who are you to decide if it is necessary or not? Furthermore, why are you justified in negatively stereotyping Americans – a diverse group of individuals?

The question was not addressed to me, but I have some tongue-in-cheek answers: > Who are you to decide if it is necessary or not? Inhabitant of the Earth. The one affected by climate change. > Why are you justified in negatively stereotyping Americans Tell me, what is the best-selling truck in US for 46 years in a row?

It’s hilarious how sanctimonious moralizing has gone from things like pornography, premarital sex and smoking marijuana to now using too much energy.

The people who complained about those issues thought they were “on the right side” as well.

But in the end it’s all just busybodies trying to force other to live their life the way they think it should be lived.

Americans tend to drive larger cars than other nationalities. These cars use more fuel. Most of these people do not need large cars and would be fine with smaller ones that use less fuel. Therefore, by choosing larger cars, they're using more fuel than necessary. An explanation is that only care about their own comfort, not the environment.

tbf a lot of murricans live in rural environments where a truck does indeed make sense because of the lots of unpaved roads. city dwellers not so much

Not really, American is pretty urbanized. Less than 20% of the population lives in rural areas. Yet the most popular vehicle for the past few years has been the ford F150. It's not being bought by rural or working class people, it's a luxury status symbol now.

> 5-10 years ago I would think this is perfectly fine. I believe I was not alone in this, but maybe I was. The energy would have cost pennies too and why whine about it? When I moved into my own home (8 years ago) I brought my 'homeserver' with me. Which was just a simple i5-2600 build with some shucked drives in it. I never thought about electricity prices when I lived with my parents. But that changed rather fast.…

>I than proceeded to put a Pi next to it, that would listen to incoming Plex requests and would start up and shut down the server with WoL. How hard is this to configure? I have a server at home I use to run a database and computational heavy code, however I am the only user so realistically it is only in use 8 hours a day and some weekends etc. However in the fear of forgetting to turn it on before I go to work (or…

If it's just that, you can have a Pi next to it and just ssh in to send a WoL command. Basically nothing to configure.

You can make it simpler to use by making an alias in your shell, or a button on your phone (with one of the countless "ssh button" apps). Or even make a web page for it (some php or python that just calls the WoL function).

OP describes a more transparent (and complex) setup where the Pi presumably acts as a reverse proxy. I'd be curious to know the exact setup too, one of the simplest ways would be to use wake on unicast: https://news.ycombinator.com/item?id=35627107

Other ways include wrapping some scripts around socat, writing your own proxy, systemd socket activation, etc.

I couldn't find it, so many details. What's the power draw on all that? A kilowatt?

Way, way too much is the answer. That amount of storage alone has got to kill his electricity bill.

he said solar, which is pretty nice if (1) he is generating excess solar in the day (2) he cannot sell it back to the grid (3) it's not cost effective to store in batteries for night use (4) there's nothing else to spend the energy on.

otherwise, i can imagine it'll still be cheaper to not run things than to run things. but it's a hobby, people spend energy and resources on more frivolous things, and those frivolous things make us human.

A diverse group of individuals who consume 12 MWh of power per capita, while it's around 6 or 7 MWh for modern European countries. It's not even a stereotype, just statistics. (got my data in two minutes from Wikipedia, so maybe not up-to-date)

"who consume 12 MWh of power per capita, while it's around 6 or 7 MWh for modern European countries."

Lol, you write that as if the Europeans were consuming half as much because they are morally enlightened.

Europeans use 6Mwh/person because thats as much as their emasculated societies can steal from Africa. May I remind you they didn't leave Africa very willingly in the 50s-70s. But they kept on stealing anyway!

Thats right. Steal. Libya, Algeria, Niger. The French convertible Franc. The French senate bemoaning just this week that Macron "lost" Africa. Lost Africa? Africa is not France's to lose!

Unlike, say, Japan or Korea that have more than just a token few LNG terminals and pay for their gas with monitors and great cars.

I would have disagreed on heat, but would love to hear what laptops that isn't an issue on.

What do you mean?

I used to have a home network, until lightning hit nearby. It came up the power connection and the copper phone connection. The modem/router/switch fried, then it spread out though the twisted pair Ethernet and fried every interface connected to the network. These days I use WiFi unless I really need low latency / high reliability in a particular location. Optical would be nice, but WiFi is the poor man's lightning s…

Couldn’t lightning just as well fry everything connected to power? In that case, WiFi will not save you.

When lightning strikes, the phone network and power network are often driven to different electric potentials, meaning a current will flow between them. When that happens equipment that is connected to both the phone line and the power will act as an (expensive) fuse.

With only one connection (power or phone) the whole device tends swing at the same potential. Damage can occur if it arcs to ground, but that's less likely as in a device the isolation to ground is typically higher than between the power and data parts of a circuit. (Extra bad news if the arc to ground happens via a person.)

Incidentally, if a lightning strike is nearby a typical consumer surge protector will improve the odds but probably won't prevent damage.

I used to have an overkill home network, complete with self hosting everything and 10G backbone. These days i'm more pragmatic. I have exactly 2 wired machines, and everything else runs Wifi. The network "rack" is simply a firewall and a 16 port POE switch, everything else network related has been retired to the closet. My NAS is gone. With electricity frequently going above €1/kWh last winter, it seemed like a bad i…

> My NAS … consuming ~35 kWh/month

Translates to 50W.
