I am really looking forward to the day we can replace chemical herbicides with weed-hunting robots. It seems such a huge market opportunity... little, inexpensive bots that can roam a field, picking out weeds the moment they appear as seedlings, never touching the crop itself, not putting anything in the soil. When I was a kid growing up in central Illinois in the 1970s, before Roundup, "walking beans" was a common s…

What is the energy source for that? Solar? Is it therefore possible to have enough solar energy to operate the machinery with enough to pull out and keep on going? And wouldn't you need a tremendous amount of batteries as well? Would seem there would be an environmental impact that could far exceed some kind of potential 'safe' chemical solutions.

It actually seems like a straightforward problem for solar energy. Just have a little "bot barn" with a solar roof and local storage, and the bots return to the bot barn for a recharge. That's almost a trivial problem.

Keep in mind the bots don't have to be very large; certainly not human-sized. Something the size of a roller skate, maybe, with specialized weed-killing tools. And if it encounters something too big or weird to handle on its own, it can mark it on a map and send an alert for human intervention.

or even better: abandon monoculture

Abandoning monoculture means completely upending the harvesting process. That's a much harder problem. Or abandoning annual crops in favor of perennials, which would have tremendous negative impact on productivity.

Don't let the perfect be the enemy of the good.

There’s a second order conclusion here that seems to get constantly lost in the conversation. On a bumper sticker it’d be, “It’s the monocultures, stupid.” When we talk about things like glysophate staying around in the soil or making it’s way into the water supply, what we really should be questioning is why so much is being used in the first place. And that’s because we grow fragile annual crops in enormous monocul…

Alternative ideas like a robot weeder [1] are interesting. This could be pretty effective on some crops. Doesn't solve the pesticide problem though.

If glyphosate is banned we will all starve.

There is no strong evidence of its harm yet. It may be an EDC, but we don't have the data to prove it.

The fearmongering has got to stop. Why wasn't Bayer/Monsanto allowed to provide expert witness testimony? Are we going to continue to throw scientific methods out the window?

Here is the paper that made me start to take organic food seriously a few years ago: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3945755/ I don't have the skills to evaluate it in depth but it seems to indicate a plausible connection between glyphosate and leaky gut, which could explain why a lot of people who don't actually have celiac's have troubles with wheat. This is conjecture on my part, but it's possible tha…

My wife used to administer Medical services in Santa Barbara country: coordinating translators and a program providing insurance to undocumented children. Many of the recipients worked the fields and I was always astonished to hear the frequency of occurrence of certain birth defects in these populations. It's entirely possible the occurrence wasn't elevated relative to populations she didn't work with or I didn't he…

They were probably exposed to 2,4D, not glyphosate

If they're using undocumented workers do you think they're going to prevent them from being exposed to a key ingredient in Agent Orange?

Sort of a tangent here, but I find very often in the workplace that my managers want me to tell them about how I "know" something will work. I never know if something will work. I can only be mostly sure that it will. It goes against my nature so much to respond to these questions the way that they want.

If it helps you out personally, it may be nice to impose a translation filter between the rest of the world and yourself here? These other folks say “know” when they mean “have confidence in” and they are looking for you to similarly say “know” meaning that. Your internal meaning of knowledge can be much stronger, but they are just asking for you to give your reasons why you think that would be the case. You can feel…

I read this, and immediately thought of one of my maxims... "Data duplication is the source of all bugs".

I think you don’t give yourself enough credit by calling it a “romantic ideal of purity;” it really does make a difference. A little pesticide is fine for cosmetic value: people buy more of the prettier fruits and veggies, great. But when you start to apply modern engineering to it, you get extremely powerful pesticides which are able to do something much more dangerous. The most talked-about example of what I am tal…

> McDonald’s French Fry Potato plant I'd love to see any info you have on that, because I'm not seeing anything at all. My Google Fu may be weak, but all I find is that McDonalds continues to deny using GMO potatoes. Also, anecdotally, McDonalds french fries are far from all identical.

I'm also not sure where the GP is going with this first point. I myself have cloned potatoes with nothing but old Russets and a shovel, and do not consider it nefarious.

Yeah, if you want to search more on it, the technique is called vegetative propagation, it is a procedure by which potatoes are cloned rather than bred. It happens to be really easy for potatoes. Searching for "mcdonalds genetically" is bound to be saturated with GMO articles.

The lack of identicality of the fries themselves turns out to be a part of McDonald’s’ broader engineering, as a matter of fact. (You could have expected this—this is the same company whose chicken nuggets come in well-defined named shapes—but it’s not terribly well talked about.) If all the fries at McDonald’s were uniformly long they would have bad stacking properties and would give you too much in your fry cup when filled, etc., so any new potato brand that they accept, or any change to their procedures for cooking their fries, must pass a bunch of stringent tests including having a certain distribution between shorter and longer fries.

In this case there is a page on McDonalds.com which specifies the only four monocultures which they exclusively farm to make McDonalds fries.

Your maxim is already in common parlance as Karlton’s principle. “There are only two hard things in computer science: cache invalidation and naming things.”

(Some add “and off-by-one errors” but arguably that is the same problem of some ‘cache’ being ‘invalid’ and never suitably repopulated…)

With that said downstream caches are often solid, if one treats them as the source of truth. “We just pretend this has not happened until we see it.” Same thing with denormalized data in a database, sometimes that's the only way to build the appropriate index which speeds things up.
