  • Capital letters give shape to lines of text on a page that make it easier for the eye to skim. Sure, they don’t add any additional information that the period does not already have (and proper names are mostly vanity), but try reading page after page of all lower-case. It will take longer and comprehension will be lower. This is the same reason why some letters extend above and below the line - makes decoding words easier by giving them shape.

    You can try it out yourself by saving this bookmarklet and using it to downcase a page! (Create new browser bookmark and paste “javascript:…” as the URL)

    javascript:for (e of document.querySelectorAll('*')){for (c of e.childNodes){if (c.nodeType === Node.TEXT_NODE) c.textContent = c.textContent.toLowerCase()}}; void(0)
    

    Come to think of it, the ease-of-read effect does look more pronounced on a full page of text rather than someplace where every post is a single sentence.



  • I agree that OP is in the best position to report the crime to the police - they are closest to the police station, they have video evidence, they literally know who the thief is - but it should not be their responsibility! OP has done nothing wrong and there are no measures they could have taken to prevent this crime (other than not shopping online at all). If OP gets a police report, OP is taking up the task of being the victim, and then BestBuy has no legal obligation to refund them at all, other than out of the kindness of their heart. Rather, BestBuy is the victim in this crime, same as if the item was stolen off the shelf at their warehouse and scanner records forged. It is their responsibility to file a police report, if they want the numbers in their system to add up. Only then could they ask OP to kindly provide the video evidence to help them out, and they’d be lucky if OP would give it to them, having no obligation to do so.


  • Knowing that the ball was gold gives you Bayesian knowledge about the boxes behind the door, since the prior probability of the host pulling a gold ball from a 6-gold door is different than from the 3/3 door. So you have to multiply Monty Hall probabilities and Bayesian probabilities together.

    That assumes the host pulled a ball at random, of course, and not a deliberately gold ball.


  • Yes! It’s an olympics game of mental gymnastics where everyone - BestBuy, DoorDash, OP, the police - try to offload responsibility onto someone else. However, a crime WAS committed. Someone is the victim. The victim is the one who was deprived of property/money and will not have access to it until/unless the thief is caught and property recovered. BestBuy thinks OP is the victim, since the item was stolen off (not)their porch. OP thinks BestBuy should be the victim, since OP had no involvement in organizing the delivery. DoorDash could also take up responsibility of being the victim, since it was their (not)employee that stole from them.

    If OP goes to the police now, they would be losing the mental gymnastics by accepting the status of the victim. BestBuy would never refund them in this case. It is in OP’s best interest to pursue the chargeback first. If OP succeeds in the refund or the chargeback, then BestBuy will have no package and no money, so BestBuy would be the victim. Then it will be BestBuy’s responsibility to report the crime.


  • The “libertarian paradise” idea is that as far as Best Buy is concerned, the item was delivered. If the DoorDash delivery driver happened to turn right around and steal the package, that’s a separate crime and a matter for the police to deal with, same as if anyone else had stolen it. And it’s OP’s fault for not picking the box up sooner, during the 3 seconds it was sitting on the porch. The porch that wasn’t even theirs. So anyway, the libertarian solution is for OP to contact police to track down the thief and either recover the stolen item or sue the thief for monetary compensation. Best Buy is innocent and no refund is coming. DoorDash is innocent too because they contracted with an independent contractor to deliver the item, and what the contractor does after the item has been delivered is not their responsibility.





  • I got excited that the paper makes concrete predictions for particle masses - the electron, muon, and tau, the quarks, and the neutrinos. For the moment, particle masses are free parameters in the Standard Model that you need to plug arbitrary experimentally-derived numbers into. A theory that can calculate them directly would be a great theory, even if it were as weird as having 3 time dimensions.

    Buuut… this paper doesn’t actually explain how it calculates all its amazing predictions. It just starts with something like “what if Schrödinger equation, but instead of exp(it) we had exp(it1 + it2 + it3)!” And I agree: yes! Let’s! What if! We should explore all possibilities, no matter how weird, if they lead to better understanding of the world. But then it immediately goes to say “let α and γ be some [unspecified] constants. Therefore the mass of the muon is 105.6583745 MeV”. Like… how?

    I thought maybe this is a paper just to announce the theory, and all the laborious calculations are in the supplemental materials, but at the very bottom it specifically writes “Data Availability: The theoretical predictions and numerical calculations presented in this paper are fully described within the text.” **Frodo mode:** Fine, keep you secrets!

    Until the author shows the actual theory and the calculations outputting all these amazing predictions, they are no more useful than that LinkedIn post that said “what if e = mc2 but e = mc2 + AI







  • He’s been in the news for several years already. I’ve looked into doing the bounty hunting thing - I couldn’t find anyone in violation! Every truck and bus driver in the city are generally in compliance of the idling limits. Only occasionally would some one-time-visitor out-of-towner who might not be aware of the city ordinance run afoul. Not sure whether people are just respectful of traffic rules, or whether this guy is a menace everyone knows about. If so, the bounty program is working effectively as intended!
