  • Thrilled you asked! So yes: Treatment is always required, but the final destination of the treated water can vary. For instance, in a lot of places they may have municipal water TO a home or business, but that may be discharged to septic, as opposed to the river. Also in a lot of areas, water may be taken out of an underground aquifer (either by private well or a municipality) but when treated it may be discharged into a river or ocean. That can create problems because if you’re near the coast, the empty space in the aquifer may be filled by salt/brackish water that can lead to salinity rises in the aquifer. To solve that some places turn to “ground water recharge”, which is just a fancy way of saying “we built a big well to put it back in the aquifer”.

    Increasingly, you’re seeing some places essentially sell their treated water. Santa Rosa CA, for instance, built an entire pipeline that goes from their treatment facility to another municipality to be injected into their groundwater.

    So yes, everywhere treats it, but the final destination makes a difference. Las Vegas (or anyone else on the river) only gets credit for what goes back into the river, so any evaporation etc is a problem. It sounds trivial, but there is a reason those other strategies exist. It essentially doubles every pipe, limits where you can park a treatment plant etc. Vegas also does some great grey water re-use. That essentially means it doesn’t go “back” but can get used many many times, limiting the initial draw.

    Wastewater is funny because it’s far from rocket science, but the numbers to implement any of it get staggering very quickly.



    1. Yes: you absolutely want the outdoor rated PVC if you’re getting sun exposure. You can cheat, it’s not like the white stuff will be immediately destroyed, but if you want something that will last a bunch of seasons, the “grey” stuff is the way to go. Double check that it’s UV rated though, and doesn’t just happen to be grey.

    2. To get around all of that, you can bury it. Because you’re just doing it for the garden, you don’t need to dig down to the frost line. Just make sure you clear the line at the end of the season. Another advantage is that you’ll minimize the amount of water that’s been baking in the sun idle in the pipes. If it’s a heatwave and they’re in direct sun, that water can get downright hot to the touch. I’ve never lost a plant because of it but frankly I’m kind of surprised by that. If you do bury, you might consider running some electrical conduit at the same time, even if you don’t put wires in it (DO however include a pull cable for later use). What you do at either end of that is a whole other project, but you can always just cap it and get it to it when you get to it. Solar + Battery usual works great for garden automation stuff, but being able to run an ethernet cable can simplify a lot.

    3. Plastic will hold up fine, but as others have mentioned you might want one of these.. The union allows to remove it. You could do a more simple threaded system IF you are able to completely and freely rotate everything “down stream” of the valve. I’m just going to say the stupid part out loud because I learned pipe stuff the hard way: A ball valve threaded on both sides cannot be loosened from one side without tightening the other (again, unless that other side can freely rotate). Edit: alternatively unions are sold separately, and sometimes you can eek out some flow advantages that way but it’s in no way worth thinking about at garden water flow rates.

    4. Finally, a last alternative I’ve seen done well for gardens that sort of “wrong done right” is putting posts up and stringing a hose over head. It kind of seemed like as much work/expense as burying it, but I guess they had the posts, it came out really sharp in the end. You need a pretty high quality hose though. Baking in the sun and sagging under the water weight can end badly.





  • I dated a vegetarian, and I love to cook. It was wild how little it took to break through the “meatless” thing. We didn’t last but I kept the skillset, and eat vegetarian at least a few nights of the week.

    I love being able to taste things at every stage without worry about food safety. Like if I don’t think a sauce is quite right, I can always try a bit. Once you kind of break through, meat freaks you out a bit… and I still eat meat!

    Edit: I’ll also add: giving up cheese and eggs would be hard as hell though… I get where that would be more exciting than meat.

    … I had never thought about it this way. You’re totally correct though. I spend way more time fighting with my windows machine than I do my linux these days. I also just have a lot less patience fighting it because it’s always due to some dumb shit it didn’t need to be doing in the first place.


  • Yes, sorry, I did oversimplify to the local network. On your local network everything is always listening, but absolutely your home router/modem in Kansas does NOT excite some wires in Tokyo unless you tell it to lol.

    And it sounds like you know way more about the software than I do, but I can say with confidence that when a router starts putting ossilating high/low on a cable, everything on that cable “sees” it. I’m fairly sure that’s why different address blocks have the limits they do; there’s only so many addresses you can have without needing to ossiclate that voltage stupid fast.

    You should look into some of the serial examples for raspberry pis/ arduinos, with your software background you’d probably really enjoy it! It’s funny to run into things like the fact that you can have issues like the wire not going back to low sometimes, and the myriad physical issues.

    And seriously check out MODBUS. It’s crazy how “simple” it is. With no handshake and a standardized data format, you can trigger all sorts of stuff. That’s the protocol that controls most people industrial things, including GIANT pumps and valves.


  • I wrote up a whole thing that didn’t post. There’s good answers here but I think that, like me, you wanted a more “voltage based” one.

    Short answer is they don’t. Everything on the network is always listening, and security is based solely off of a handshake. Everything is always employing a fancy multimeter that measures voltage high/low as a 1/0 turning it from bits to bytes etc. The router listens to that and decides where to send it upstream, which it isolates from downstream.

    For a realllllly basic example look at the modbus protocol. That’s also why industrial equipment folks get real touchy about network access. For things like computers, theres talk back and forth to verify. Modbus is just “if the byte is the thing I do the thing”. But fundamentally, that’s the physical basis: all devices are always listening, the TCP/IP stack is what tells them what to disregard.


  • Prey (2017) is an awesome FPS/immersive Sim. As in, it plays like a shooter but how you take each engagement is highly up to you. You can go in guns blazing, there’s usually some way to use the environment, go out of your way to get robot helpers, mind control one of the enemy, sneak past entirely. It’s one of my all time faves because it has depth but draws you in like an fps. I love stuff like obra din but don’t always have the energy to get lost in them.

    And the plot is awesome. Not a ton of replay ability (imo, but I’m difficult there) but definitely a meaty amount of time. highly recommend headphones.

    Haven’t run it on the deck but a quick search shows people are really happy with it’s performance there.
