p<=0.05 is so easy to achieve for actual positive results (just increase sample size) that I don't think it's productive to treat any result with p>0.05 as positive evidence for any purpose other than deciding to rerun the study with a bigger sample size.

I'd say it's very sensible to assume absence up front before there's convincing evidence of presence. Sure, personal biases influence our evidence thresholds a lot, and often people demand unfair rigor that cannot be practically met. But the opposite is also true - sometimes people will believe in presence with zero evidence if they like it enough. The latter is far, far more dangerous than the former.

Evidence can be strong or weak. Every positive study result is evidence of presence, usually strong evidence. Every negative study result is evidence of absence, usually very weak evidence.

Note that we didn't call it junk DNA until we learned a whole lot about how DNA works and formulated a theory in which junk DNA doesn't do anything for good reasons. In a way, lack of understanding prevented us from calling it junk DNA earlier.

Of course it's still possible for the theory to be wrong and the so-called junk DNA being actually important. It's only junk according to our classical, non-quantum and non-relativistic theory of junkiness.

Whether we like it or not, em dashes are effectively verboten in online discussions and blog posts if you want people to take you seriously. If the idea that excessive hyphenation is an AI tell gains traction, it too will become impossible to use without ruining your credibility.

> What if there was one day a year where it was expected for people to speed through your neighborhood at 20 over the speed limit, which ends up with a bunch of people driving into houses with their vehicles?

You mean All Saints Day (1st of November)? No, thousands of drunk drivers taking dozens of innocent lives and hurting hundreds more, year after year like a clockwork, is still not a reason to ban trucks, or any other car type. Or to cancel All Saints Day, if that's what you're implying.

> Stealing electricity is already illegal.

So is shooting a house with fireworks. I'm against a general ban on doingelectrical work yourself, and against a general ban on fireworks.

> How would you feel if your house burned down because your neighbor did something stupid?

Probably the same way I'd feel if it burned down because my neighbor did some other stupid thing, like drive into it with a truck or try stealing electricity. There would be many feelings probably, but none of them would be "trucks/DIY should be illegal".

If code is predictable then it should be extracted into reusable functions/classes/modules and reused in accordance to DRY principle. I'm not a fan of this AI future where coding standards drop to the floor because humans won't be reading that code anymore.

There are cities in the US that have 2.5x the population density that Zurich does. Rural Texas might have this excuse, but New York City absolutely does not.

> If you have 1000 applications for every job, and you know that a bunch of these applications are "a bad fit", to put it mildly, you have to filter. And you cannot realistically give every resume a good, human look.

At 10 seconds per resume, it would take you 3 hours to go through all 1000 resumes. I don't know what you consider "good" and "human", but my human eyes could easily do good enough, fully manual pre-screening at a rate of 1 requisition per day.

"Being online during the short time" heavily favors bots. In a way, AI screening tools saved us from the future of everybody buying resume-spamming-as-a-service because it became as important to use these as getting a college degree.

Sometimes, the relevant timezone is whatever the local timezone was when and where the timestamp was recorded. Which is information that's lost on UTC conversion.

Sure, you can reconstruct it if you stored the "where" part somewhere else, and associated the "where" with the timestamp's timezone (e.g. the Offices table has a Timezone column that you JOIN with the punch-in times). But that assumes you stored it somewhere else. It also assumes said storage is readily available. It also assumes there was no human error in recording that value (what if the office was accidentally assigned Seattle PST instead of BC PST back when it didn't matter?) It also assumes it was possible to record it correctly in the first place (what if the office is in Kimberley, BC but the software only allowed selecting BC timezone?)

Alternatively, you store the timezone directly in the timestamp itself and avoid all these problems and more.

If people were perfectly rational robots, this could work. Also, sales jobs wouldn't exist and politicians would be held accountable for their promises.

In real world, sales tactics work. People can be influenced to pay more than they thought they're willing to pay. Scalpers know this and exploit this at scale. A Vickery auction gives basically zero opportunity to get talked up. People will bid at the "thought they're willing" price, and scalpers will outbid them. Then the same people who underbid on auction will go to eBay, see it listed at "influenced to pay more" price, and buy it for much more than they bid.

And yes; the vast majority of eBay auction bidders are indeed scalpers, whose day job is to look for cheap deals that they can resell for more. It's extremely rare in this day and age to actually take advantage of eBay bidding to buy in-demand stuff on the cheap. It's much easier when there's "buy now" option but you need to be fast and lucky because you're competing against scalpers here too. Of course things are different for stuff that few people want in the first place - scalpers are not interested in those because they're too hard to offload, so you get your fair chance.

But which tzdata? Do you have the timezone or do you not have the timezone? If you have the timezone then why is your timestamp in UTC and not in the timezone that you have to store alongside the UTC timestamp?

"UTC or otherwise" is important. Are you storing otherwise, or are you storing UTC? There are times where storing otherwise will lead to data loss in case the law changes whereas storing UTC would work (when you care about a literal point in time, like access logs). And there are times where storing UTC will lead to data loss in case the law changes whereas storing otherwise would work (when you care about wall clock time, like punch-in times).
