This seems like kind of a fluff piece, I don’t see any details about the actual technology. The whole article is about how proud the company is to be partnering with midwestern farmers. Can anyone provide a link or more information about how they are able to distinguish weed from crops, and by what mechanical process the weeds are removed?
Interesting that this was literally the major plot point in one of the GI Joe movies. I wonder if they got the idea from the movie. If you google around, the weapon in the movie created a lot of discussion about the real life viability and physics involved about this exact topic.
Here’s a clip of the weapon being used in the movie: https://m.youtube.com/watch?v=jOKf5r_JMAo
These requirements for faxing are becoming almost silly. Not only is the PSTN infrastructure in some areas so bad (40 year old corroded copper lines and such) that there are potential problems every time it rains, but incumbent carriers are trying to do everything they can to rip down what is left of the copper infrastructure. I don’t blame them as this makes practical and financial sense (remove copper phone lines, replace with fiber, offer data and voice through the fiber).
The dream is that the PSTN will be done away with entirely, with all traffic going through the internet.
A big problem is with fax machine manufacturers simply claiming that their machines “are not voip compatible” which is ridiculous, but the extra effort involved with getting faxes to work smoothly over voip can be a nightmare, and not something any vendor wants to be involved in supporting.
The result of this is clients with $15k fax machines reporting a myriad of problems, which the fax machine vendor claims that the only solution is a PSTN phone line for the machine, which in many areas is no longer possible due to the incumbent carrier phasing out the infrastructure or making it incredibly difficult to obtain.
There are a lot of “Efax” services whose purpose is to get around this problem by making the “fax” step just a transparent formality to appease regulatory constraints. Users can send an email with a specially formatted subject, then the “efax” company will actually “fax” the document specified in the email to a phone number owned by the efax company, which is then emailed to the intended receiver.
I'm not sure that course completion percentage is necessarily the best metric to be drawing conclusions from. I will often sign up for MOOCs and courses for a single talk, chapter, or topic that I'm interested in with no intention of actually completing the course. I wonder I'm an outlier in this regard or if this approach is much more common than the author of this article realizes.
Why is this being downvoted? If he isn't "playing dumb" then this is an excellent realization as to the negative impact that tariffs/quotas/etc. have when compared to free trade. True that it is "common knowledge" among those who have studied markets or economics, but not everyone has given these concepts serious thought, and if articles like this lead people to make this connection, I'd say that this is an excellent outcome and don't think commenting on this newfound understanding should be downvoted.
What about a scenario that describes an event occurring during a discrete amount of time during a set length of time? For example: A teacher says that he will give the class a surprise pop quiz at the beginning of class some day next week. How does reverse induction fail here?
Can this concept be generalized to the point where NOTHING is a surprise? For example if a surprise party is planned for someone at some point in $TIME_PERIOD, it can't occur during the very last hour/minute/second of $TIME_PERIOD because it wouldn't be a surprise. The surprise party can't occur during $TIME_PERIOD - 1 because this would be known as well. Repeat this ad infinum just like the weekdays in the article.
