This is the classic precision versus recall discussion. The discussion centers around how you think about the cost of a false positive versus false negative.

Some people think it's fine for the process to have low precision but high recall. Low precision is that of the number of conversations the process flagged as a positive, some unacceptable (to you) percentage turned out to be a not/false "positive". High recall is that of all the actually positive conversations, the process flagged an acceptable (to you) percentage of them as positive (i.e. only "missed" a few/false negative).

What does it cost to wrongly identify conversation a positive when it's really not a positive (false positive)?

What does it cost to wrongly identify a conversation as a negative when it's really a positive (false negative)?

You decide.

In my experience, you can weaponize processes like the Five Whys or the Amazon Leadership Principles. I don’t think that means they don’t have any value.

That being said, in this case, I agree with your manager. Both the QA team and your team had fundamental problems.

Your team (I assume) verified the functionality which included X set of changes, and then your team made Y more changes (the flag) which were not verified. Ideally, once the functionality is verified, no more changes would be permitted in order to prevent this type of problem.

The fundamental problems on the QA team were…extensive.

The problem is that these companies are locked into years long, multi-billion dollar contracts with the sports leagues. Those contracts are predicated on their existing monetization model. The economics of those contracts no longer make sense if the model changes. A lot of money is on the line. So they are going to fight hard.

Uh, it’s given you a lot in return. It abstracts away a lot of the human condition for a lot of people. Personally, I don’t want to go back to growing food to feed myself and bartering. Most people are aligned with that point of view.

Edit: In fact, it works so well, you can ask what it does for you.

Isn’t this the deal we’ve made? You can, legally, deny someone access to private property for any non-protected reason.

On the other hand, if the private property was constructed with public monies, which MSG probably was, that’s an interesting debate. Should the involvement of public money confer first amendment protections of some sort? I think it should.

Edit: You can’t use “my” money to build something and then ban me from it because I said something (non-protected) about the CEO of the company that owns it.

Output metrics are things you can't control. For revenue, you can't force people to by your products. Inputs metrics are the things you can control. You can (to a degree) control price and selection. And you've established via analysis that those inputs metrics are associated with the output metrics.

A key part I think people miss is to make _sure_ your input metrics and output metrics are correlated. You would intuitively think that, say, lowering outage minutes would be correlated with revenue. And as a result, you should invest engineering and other resources in reducing outage minutes. But maybe experimentally or via some other type of analysis it isn't. Maybe users will tolerate some amount of outage minutes without materially impacting revenue. You can then utilize that knowledge to prioritize. Rather than investing in resiliency to improve outage minutes, you invest in something else because that will have a bigger impact on revenue.

Yup. If this isn't Congress' intent, all they have to do is pass a law saying so. "...when Congress addresses a question previously governed by a decision rested on federal common law the need for such an unusual exercise of lawmaking by federal courts disappears." - MILWAUKEE v. ILLINOIS via Wikipedia.

Given how A to B to C the logic of the ruling is, this case seems like a gigantic waste of the Court's time, though it was 6-3. So there was significant dissent.

I don't see how this weakens SEC enforcement. They can still seek enforcements. They just have to seek them via a trial by jury of your peers, which is one of the most foundational aspects of American law and one of the issues that led to the American Revolution.

Yeah. Reading the opinion, the logical argument of criminalizing a status (homeless) versus an action (camping in public) makes sense. The action applies to everyone.

We as a society need to continue trying to solve the problem of homelessness. However, leveraging the 8th Amendment, in part, to do it doesn’t make sense.

Nvidia’s profit margin for the H100 is supposedly in the neighborhood of 1000%. So they can afford give up some profit if they need to. Couple that with the fact that the software toolchain advantage is significant. That being said, I’m all for more competition in the space.

This is a classic ethical dilemma. Self-driving cars will kill some amount of people via malfunctions, accidents, etc. Some amount will be children. Should we ban the development of the technology? What if it only killed 1 child? What about 10? What about 100? How many dead children is the benefit of self-driving cars worth?
