I fully agree all your logic. But then I see a counter of "public sentiment" where I bet most citizens would be outraged by million dollar salaries.

I've heard two side the the Protobuf/streaming idea. On my first introduction, it seemed you could. But later reading leads me to believe it is only almost streamable: https://belkadan.com/blog/2023/12/Protobuf-Is-Almost-Streama....

* I do acknowledge you qualified the question with "better".

> Some see a university education as an example of this: it costs cleverer and more conscientious types less to get a degree than stupider and lazier ones, allowing employers to distinguish between the two.

Wait, how? If two people both have a degree, how does that help distinguish who is stupid?

Could it be kinder, at times, to play to the cultural norm? If people have been raised to say "sir" to their boss, could asking them to do otherwise cause them discomfort without benefit?

I have struggled with this myself, as I don't believe work hierarchy should convey any fundamental difference between people, and we are best off treating each other as equals.

As an American from a region with an atypically dry and reserved culture, the Australia attitude sounds nice.

I was about to say I thought you might be mistaken because you can always use some variant of "group concat" to get sets of fields to show in comma seperated form...

But then I realized even with that, I couldn't get the output under discussion without subqueries. And I don't consider that a win for me.

New comment by sopooneo in "The Art of Finishing"

sopooneo — Mon, 02 Sep 2024 21:41:46 +0000

Agreed completely. Sometimes I've worked hard to put the finishing touches on side projects to make them usable by others and have been pleasantly surprised by the interest. But in most cases, even when I finish, almost no one cares.

And while finishing is an important lesson early on, just so you know how hard that "last 20%" is, it's grueling and not typically very informative or unique after that first couple times.

So I'm now squarely in the camp of do what I want and finish what I want on the side, with no guilt. If I enjoy the journey I call it good. Finishing is for the day job.

New comment by sopooneo in "The physics of airplane flight"

sopooneo — Sat, 06 Jul 2024 02:20:50 +0000

Crud I think you're right. I had it in my head that in steady flight, the plane had zero change in momentum, whereas, the air, collectively, gained net downward momentum. So to balance it all out, the earth must be gaining upward momentum (though of course spread over such an enormous mass as to make the velocity term imperceptible.)

You clearly know more about this than me, because I'm currently Googling to understand what "diametrical corners" are. But in a simple implementation, wouldn't the x and y velocities both be reversed at once with a corner hit, both side and top/bottom collisions having been detected "at once" in the same part of the code between updating positions? And then the logo would just bounce out exactly the way it came in?

One other weird thing needed if you want your momentum numbers to balance: every plane in the sky is pulling the earth up towards it ever so slightly.

Honest question: if wing's cross section has a big curve in front, how do determine which point exactly constitutes the "leading edge"?

Exactly. At $500 or $1000 per record, PII starts to look highly radioactive. Companies would be avoiding it's collection with a passion. And those that had to hold it would be compelled to do so less stupidly.

Completely agree on this. A company-killing level of fine, based on number or records exposed, is appropriate. Then the insurance companies would not ensure companies unless they passed stringent audits around best practice and data hygiene.

I would argue that, in practice, they are not completely separate. Too much abstraction makes it hard to tell what the underlying algorithm is. And even if you can figure that out, makes it hard to optimize.

Got it, and that makes sense. Thank you. I couldn't even figure out why I was confused, but then looking at the interface, I think I may have been mixing up the order fields are noted, vs cardinality.

Fantastic. I was literally just looking for something like this. I'm using it now.

One thing that may be me getting my brain reversed, but when you set the "cardinality" of a relationship the "1" and "n" markings on the connecting line seem to be reversed?

No dog in this race either way, but what is Michael Lewis meant to have done? Is it just that people feel hist treatment of SBF in Going Infinite was too lenient?

I'm a Docker amateur, so this will be a dumb question, but if you were using that technique after every run line in a DockerFile, wouldn't they be the same every time they're run? Like, it's random, but it's the same random values stored in the file, so wouldn't the lines get cached? Or did you adjust the DockerFile each time?

Or am I completely missunderstanding?

Total aside: but related to ambiguous true/false designation: A lot of times when people write articles like "Ten Myths About NodeJS", it is unclear in each of the numbered items whether the stance initially described is the incorrect myth, or the correct view as proposed by the author. To make it worse, some writers vary the structure between items!

That is my reading too. But why was the multimeter connecting up telemetry? That seems very strange to me.
