>>The reason is that if you're truly good at something, if you have a real talent for it, then it's easy for you to do it well from the start, so you rarely judge it or realize how good you are.

I've often wondered about this (beyond basic abilities). I'm sure there are exceptional people for whom this is true but in my experience most people start out not being very good at what they later end up being really good at.

Would love to know if there's some sort of data / research on this.

Seems to be fixed now:

"On Wednesday, Apple released iOS 17.1. Among the various fixes was a patch for a vulnerability, tracked as CVE-2023-42846, which prevented the privacy feature from working. Tommy Mysk, one of the two security researchers Apple credited with discovering and reporting the vulnerability (Talal Haj Bakry was the other), told Ars that he tested all recent iOS releases and found the flaw dates back to version 14, released in September 2020."

Replacing sql analysis would be more correct than replacing a sql analyst.

prompt: write a short essay as a scientist which is better, celsius or fahrentheit

partial answer which some faulty reasoning about precision:

First, the Celsius scale is based on a more intuitive and logical reference point. The Celsius scale sets the freezing point of water at 0 degrees and the boiling point of water at 100 degrees, whereas the Fahrenheit scale sets the freezing point of water at 32 degrees and the boiling point at 212 degrees. This means that the Celsius scale has a smaller unit interval, which allows for more precise temperature measurement.

> understand that your want for a new vehicle every couple years

you're making a lot of assumptions here. In general I'd agree with you.

AFAICT it was totally random. I would keep my hands on the wheel at all time but even then it felt very surprising. After a couple of times I never engaged it again, except for couple of times to show others how ridiculously bad it all was.

Slightly off topic: I am the owner of a Tesla, and until recently a 2021 model 5 series BMW. The 5 series had 'keep your lane' and 'follow' functionality, and I've been absolutely flabbergasted that this functionality made it on production vehicles. It would give up in the middle of basic turns in the road in such a way that it tried to turn you straight into the divider. It was comically bad, except that it wasn't funny.

The Tesla (not a fanboy btw) is miles ahead in this regard.

A lot of the comments (not all) really personalize the issue by using Jeff Bezos as the villain, when it's the system and laws that have allowed him to capture so much wealth that is the problem. And IMHO, that's the part that needs addressing, by putting a progressive tax in place.

Jeff's not the enemy - he's been amazingly successful within the rules that we as a society have made. Some of these rules are oppressive and bad and we should fix them.

I like the thinking. I visited the Netherlands, and some of the last mile vehicles I saw there are amazing. Think electrified cargo bikes - stunning and moz def the future :)

Its (obviously) not about the renumeration of any individual, but about accountability of the source. There are several examples - Tabacco, Asbestos, Bopal, Oil, Medication, ... where billions of dollars of fines assessed against the sources, not exactly small numbers.

I'd love to see a class action lawsuit keeping the people who lied accountable for the amount of additional waste in effort, resources that are used to separate and collect these separate streams.

Stuff like this (h/t @neltnerb): >>In almost all locations, PLA, "compostable plastic" (often labeled number 7 or 0 for marketing) is not only not recyclable but actively contaminates compost and recycling plants. I see all these places using "compostable plastic" because they think it's more environmentally friendly. It's a noble goal, it makes me so sad to see.

So many groups would have standing to sue here...

I love seeing this: there are massive opportunities to build fundamentally differently architected database based on evolving computer architectures (ram, persistent ram, GPU, heck - even custom hardware) as well as improved understanding of ACID in distributed environments. SQL remains an important API :)

Fantastic implementation - rock solid. It does feel like the OS X version trails the rest of the platforms, is that true ? It hasn't mattered much for the work I've done with it but curious.
