Drip irrigation is kind of a thing out here in the desert...

And then there is burried drip irrigation...

more tricky frequently because you need to measure the moisture for each plant as maintainance is difficult without, but this is generally the most efficient low cost method in very arid regions from what I have seen (dad is prof in the field, so exposure is years of unpaid labour as a child and student)

>Having watched Clarkson's Farm, I can't help but feel that farming is extremely antiquated. That's like saying you watched The Bachelor and now have Opinions about marriage.

You're telling me I have no clue. I don't disagree. But what would be much more interesting is for you to address the points I made.

You didn't really make any points worth addressing.

If you want to drink Soylent, go ahead. But even the predominant ingredient, soy, comes from agriculture.

This looks fun but not really useful. My hope would be that in 20 years everyone has a little bot that 24/7 runs a garden for you and provides every family with 80% of their vegetable need. Imagine the amount of acreage we could return to nature / co2 sinking.

Every family having to have a robot instead of a handful of tractors for every ten thousand families or so. And that is likely a less optimal use of acreage. I think what you might actually be advocating for is “people should convert more residential land into gardens” which is always fun. I love my garden as a hobby. We keep trying to un-invent the division of labour. Edited for unnecessary pre-coffee poor behaviour…

For a while I was considering something similar, where instead a couple of windows at a home would be miniature greenhouses/aquariums with openings arranged so that if the interior access was latched it would be impossible to gain access from the outside, but it would be possible to fill up consumables and drop off additional items (think tilapia for a scheduled dinner, but the usual protein product would be shrimp).

That said, I think making room for something like:

is perhaps a bit more marketable (though they missed out by not sizing it to fit next to a refrigerator).

Well, you're hearing it from a guy who has written hardly any Elixir or any other BEAM language. (For a proper intro I recommend this video https://youtu.be/JvBT4XBdoUE ). Less practitioner, more fanboy. So I may not be the best source. But I'll try anyhow. The BEAM is a virtual machine, I guess kinda like the JVM. So just like you can write Java or Kotlin or Clojure or a million other JVM languages, so too can you w…

Different person, but thank you for the writeup! Very interesting. For anyone else reading: Please write more comments like this, they're one of the best parts of HN.

To elaborate a little bit on the supervision tree thing then: there's a bunch of different behaviours you can associate with process failure depending on your needs. Let's say you have a Postgres connection pool and for some reason the pool manager process dies. You can set it up so that the death of the manager will:

- kill all of the child processes that the pool was managing

- return an error to all of the request handlers who had active queries going while not touching the request handlers who didn't

- restart the pool manager

- once it's running, respawn the managed pool processes

This is all machinery that's pre-built into the OTP runtime. While that's all happening your app as a whole can keep trucking along and everything that doesn't need to make a database query carries on without even noticing that something was amiss.

The slogan "let it die" gets tossed around the Elixir/Erlang community quite a bit. This is referring to Erlang Processes (the internal lightweight processes, not the host process with a formal OS PID associated with it). Your whole app doesn't die, just the broken parts, and the OTP supervisor subsystem brings them back to life quickly.

Each person owning their own farm is orders of magnitude less efficient that one large farm serving many people.

ROI shouldn't be calculated based on the costs of transportation, because no one goes to the store to buy just vegetables (and not everyone drives to the store, it's a purely suburban american thing). Not to mention 'CO2 costs' that you don't pay at all

> and not everyone drives to the store, it's a purely suburban american thing

I live in a german town at the edge of a large city, the grocery stores are evenly distributed among this town, max 15 minutes by foot or 5 by bike. I love my bike and use it all the time. On a nice day, there will be 20 bikes and 60 cars at the store. On a rainy day there will be 2 bikes and 80 cars at the store.

"Only americans take the car to the store" is a myth that you shouldn't spread.
