    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.


  • That and post-scarcity doesn’t mean “zero scarcity”. Like if someone wanted to create a picard funkpop the size of a planet, I don’t think they’d be allowed the resource budget.

    It’s like how it doesn’t matter where you live, if you want to buy on the silk road, you need bitcoin. Presumably even the federation can’t just make latinum whenever they please, or we wouldn’t see them haggle with it. Although, it would be fun to see that they could and just take the responsibility of not crashing non-federation cultures entire economies very seriously, either out of respect or treaty.

    Damnit, I want a LD episode where the crew is frustrated and desperately wants to just “buy” their problem away but can’t because an economist at command says it’ll mean they have to rescue all these non-federation colonies that are currently self sufficient. Come to think of it it’s right there with the “you break it you own it” concept of the prime directive.



  • Agreed, and I spent like a decade in protein engineering and pre-biotic chemistry.

    And if someone really wants to be a pedant about it, go ahead and prove conscious “intent” is inherently different than, not just a more complex form of, what’s going on here. If someone’s managed to solve all of the philosophy around consciousness, self, and intent, they could really save us all a bunch a time! Until then, pedantically, you’re not wrong to say the plant “knows” to do this as much as I “know” to pay my rent; it’s all just chemical reactions based on environment.

    … Or we could allow people to enjoy the pressures and reasons that give rise to the subtle aspects of organism in this complex ecosystem we call earth without being a dick about it, and trust that the level of language specificity will increase/decrease commiserate to the degree of precision the topic requires.


  • not only native, but the ONLY place. I’ve got carnivores from every continent (accept Antarctica, obviously), and thats STILL my favorite fact.

    It does make sense they’re so rare though. Most carnivory you can picture the evolutionary path: Something had a mutation that kind of made a cup, something had a mutation that kind of made the leaves sticky… etc. You can see it happening one step at a time with minor advantages (and therefore survival) at each step, until they kept compounding into more and more complex and specialized structures.

    For a VFT… multiple things had to happen at once. There’s no advantage to the motion until you can also digest and adsorb the material. There’s also no advantage to a partial motion that can’t trap an organism. It’s really wild they exist!


  • We’re used to getting our energy and building blocks from our food. Plants get their energy from the sun, and their building blocks from the air (CO2). They get water and some minerals, but a plant is made up off solidified air. It’s like if you could be solar powered living off just air, water, and an occasional multi-vitamin.

    Anyway, carnivores don’t really get energy from their prey, just the nutrients. It’s like self fertilizing.

    So most fungi do have a lifespan, they have teleomere decay, and when you’re cloning mushrooms (from propagating mycelia) you have to let them go to fruit (the part that looks like a mushroom) every now and then. It’s a pain in the ass.

    But like the other poster said, they play it fast and loose with which part you consider the “organism”. My favorite thing is that they do cytosolic streaming. Genetics can be a pain on mushrooms because not only do they share nutrients and metabolic burden through mycelia, they can share nuclei.

    One of the weird convienent realities we used extensively is that cells are big enough you can spread them over a petri dish with a little loop, and if you diluted the initial sample enough, the colonies that developed were, practically speaking, from one parent cell. So you could try to modify a bunch, and then plate them (spreading the cells around) and pick individual colonies that were all clones from a single parent. Fungi mycelia means the nucleus isn’t stuck in one cell. It also means expression levels can be variable (some cells will have multiple nuclei, and then later maybe they don’t).

    Fungi are a godamn pain in the ass to study. They’re not mysterious, they’re not alien, they’re just fucking assholes.


  • 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.



  • I don’t know exactly what you’d call it, but respectfully, it’s not just a big number.

    Ignoring other isotopes (which, all you need to do to adjust for that is use the weighted average), if you have 12 grams of carbon, 63 of copper, etc you will have 6.02E23 molecules of each. The value is implied by the fact that again, atoms have a consistent mass and react in integer quantities. A mol could have been any value, but that’s like saying that a meter could have been as well. The existence of some value that marries the atomic mass of each element to a quantity of atoms is inherit the same way pi is inherit to a circle.

    A mole isn’t just convenient. I’m sure there’s a youtube somewhere that explains it but advagadros number is a product of the fact that: 1) every atom of an element has a weight (or at least an average) and 2) atoms interact in integer quantities. If you put those two together there is a common multiplier for a stochiometric equation that is related to the mass of a given atom in that stoichiometry. That multiplier is the the mole.

    edit: I guess that’s kind of a factor, but it’s really more of an derived unit. If there was a new element discovered a mole would still describe it’s stoichiometry, and IIRC that’s how a lot of the periodic table was filled out my Mendelov.


  • So way late, but no that’s shifted a lot. This is anecdotal but does speak to a lot of industries: my understanding is that pizza shops now live or die by cheese prices.

    Labor, while fluctuating, doesn’t move a ton month to month. Dairy can.

    That’s like I said anecdotal, but broadly, real-estate, equipment purchase/finacince has all been so hyper optimized it squeezes the business owners out.

    It doesn’t matter the market. PIZZAOVEN-XL will sell it to you, let you leverage payments against your home equity, grab it back and resell it. They can deal with the cash flow issue. They are “assembled in America”. They don’t care if you go out of business. They’ll do it again for the same person that moves into the same space trying to do the. Exact. Same. Thing.

    And I’m not trying to draw a blanket statement across all industries. I’m just saying the wheels that make every industry move are smarter and literally longer lived than anyone starting out, and there’s a reason “John deer” and “John deer finance” are seperate companies.


  • So I’m stretching it a bit because at the end of the day this really does apply to more than restaurants, but the other commenter had it right.

    Things like rent, insurance, etc go into the cost for well above the plate. So the ingredients are one thing, but you have to make up the cost of rent, paying the staff when there’s low customer volume, all the insane amount of costs that go into running a business. That server has to make up for the cost of printing menus and delivering them by mail.

    None of this is the servers fault, who should get a fair wage, but it all adds up in a way that makes it hard for the owner. In fact, the person who sold them the grills, refrigerators, and all the other equipment, knows exactly and empirically how hard it is and sets their prices accordingly.

    And it’s not like that company’s delivery drivers, techs, and fabrication workers also don’t deserve a wage. Or the Tyson folks that are plucking the chicken delivered.

    The issue is, at the end of the day, those companies probably should be less profitable. But instead of accepting that, we put all of the companies that make all the stuff that run that restaurant into bigger companies that are now part of mutual funds, and they sell it out knowing they can grab it back if it goes under.

    So you might be able to get away with making a few plates and some money, but trying turning it into something that will let you pay your rent and put your kids into a school. “Bob’s Burgers” is pretty true to life.

    Restaurants have notoriously thin margins. I’m not defending this bill, and there are definitely awful practices out there, but it ain’t easy. Even a $34 dollar steak only kind of covers all the ancillary costs that make it happen.

    The biggest issue with the crunch we have going on is that food (prepared or otherwise) should be way more expensive, and that shouldn’t be an issue because most people should be making way more money. All of those should/shouldn’ts got way out of whack over the course of decades, and the circus only continued because people found crappy ways to keep it going.

    It’s a lot of industries. Construction is a great example. The developers make money. The material vendors make money. The builders make money. The sub contractors who actually put the parts together get haggled on invoices and take the lower amount because they have payroll to make and equipment loans to pay. Loans that are happily given out because the equipment can be easily repossessed.

    It’s a very good thing everything is correcting, but it’s going to be an ugly process as workers get their due and pass the burden on to the small business owners.
