Some farmers with apply roundup just before harvest in order to desiccate the plant. This makes harvesting much simpler and cheaper, as you don't have to wait for the plants to dry naturally, or deal with moisture rich plants after har

I assume you could achieve the same thing with less complexity and more cheaply using a fixed system. Either having more than one sensor or using mirrors or something. In fact, I'm sure that the camera systems in place are already doin

My understanding is that they detect moving obstacles much more easily than stationary. This is because almost everything in the environment is stationary to the car, so it is hard to distinguish between stationary things in your way and st

The article was careful to put that quote in context, which you haven't supplied here. They were almost certainly referring to the system being used against debtors who are not paying their debts. It's not a case of saying "p

Well sort of. Double spending is just convincing the network you've sent coins to multiple places, and then undoing all of the transactions that were 'paying' for something (in this case paying for credits at an exchange). Th

There are many strict orderings that can be used, but we just need one. Since each number is in a physical draw in a physical room, and no two draws can occupy the exact same space, there is a strict ordering of the drawers given by each dr

For what it’s worth, I believe you. I sincerely believe that people would have been fired for inappropriate use/access of data. My comment is a deeper one. The incentive in general is to improve value produced, and identifying bad ac

Happy to be wrong. Are you saying this person was fired before it became public that they had misused data? Or was it reactionary?

The bigger issue here is that they reacted to this event, rather than proactively managing it. From the article, “Access to sensitive data is logged, and the company has automated systems designed to detect and prevent abuse”,but if that we

I haven't yet seen a good explanation as to why this focus on randomness is so prevalent, but chance really is almost irrelevant when it comes to evolution. The main mechanisms of reproduction and selection that you point out have almo

Love ffmpeg! I was trying to do something the other day and couldn’t figure it out, if anyone has any ideas. The end goal is to provide a set of video files, with time stamps for each, splicing them into one file while removing parts I don’

Makes a lot of sense, but maybe a slightly longer bow to draw given that we would never us xx/99 as a percentage in decimal :)

If it was a hex percentage it would still be 81/100, or in decimal 129/256 = 50.39%

That's not really true. Parts of the arctics are definitely deserts, but that is not true for all of the arctic regions. Looking at the relevant parts of wikipedia [0] and [1], "annual precipitation averaged over the whole pla

One of my most enduring memories is putting on the audio book for "A Brief History of Time" to listen to on a long drive home with my brother. I'd read and listened to it before, but sitting there watching my brother listen t

Well, I wasn't prepared for that. Almost skipped over it, so anyone else trailing through who catches this, go and read it.

If you haven't seen it there is some, according to Armstrong 'persuasive', evidence[0] that he did in fact say 'one small step for a man'. [0] https://www.space.com/17307-neil-armstrong-one-small-ste

To be perhaps slightly more accurate, it's like a major version 5. Almost (if not) all missions include changes of some kind; the manufacturing blocks each have significant, incompatible differences in parts. Upgrading the grid fins wo

The article seems to be behind a registration wall - are you able to provide a summary? Also, do you know if this is a widely held position or just emerging? I found a couple of things, but none of them are as clear cut as "it's o

I like to think that rather there is no reason for either country to want the island full time, except to say they have it and the other does not, and plenty of reasons to keep a quirky tradition that serves as occasional reminder of an old

I hadn't heard of non overlapping magisteria (NOMA) before. My immediate thought was that if you assume the 'teaching domains' of science and religion do not overlap at all, then the domain of religion is vanishingly small. I

Yes, it's almost exactly the same mechanism. I think the big difference is that people, intending wholeheartedly to do good and help these countries, instead cause significant damage. Things like this are one of the reasons I find the

A thesis I've been hearing a lot about recently goes something like the following. It doesn't speak directly to subsidising food production costs, but is related to the same idea - what is wrong with cheap and plentiful food? Here

It's a good point, though I don't recall seeing many posts that have been flagged where I think they should be resuscitated. In this case, I think the correct action probably would be to unflag it, and change the title. Maybe the
