I sent my application in a week ago. So what you’re saying is I still have a chance?

Every engineer should be familiar with at least the basics of computational complexity.

If you're stacking loops, you ought to know what that does.

You also really ought to also what your core data structures are, how they work under the hood, and how the different operations on them consume space and time.

If you don't familiarize yourself with at least those bare basics, you're doing yourself and your customers (and your future maintainers) a disservice.

I’ve always done load tests, cured bad code, re-tested. Static analysis can discover most of these kinds of problems. It’s entirely possible I’ve been resolving big O problems intuitively over the years.

I liked the presentation (right or wrong), but wanted to point out I’ve been in IT as a coder and architect for 40 years and never once needed to know big O notation.

Which I think is the complaint here. The article author might have made an effort to connect it’s significance to Internet solutions like Search.

I assume he didn’t because that’s already been done.

No one has invented Asimov’s positronic brain or anything like it.

We don’t even know how.

ChicagoDave commented on How to teach your kids to play poker: Start with one card   bloomberg.com/news/articl... · Posted by u/ioblomov
ChicagoDave · 18 days ago
I’ve taught all five of my kids how to play poker, and if they ever sit down at a cash game consider their stack gone and play the cards (remove the dopamine chaos). Learn the math, betting strategies, and look for villain patterns.

These all directly relate to real life.

I believe in it so much that I have a tournament training app startup: https://mach9poker.com/.

There’s a company in Chicago that teaches women poker in relation to business: https://pokerpower.com/.

Bankroll management is a critical skill regardless of the use case.

I attended his high school. The foyer had a panoramic display of the Apollo 13 story. He spoke at our 1982 graduation.

In your world view, what would you personally do if you start one, or multiple, incredibly successful companies and amass $ billion(s) of equity in the process?

Without subsidies from the Obama administration, Tesla never succeeds.

Without government contracts, SpaceX never succeeds.

Without a mysterious visa, Musk never stays legally in the U.S.

This is the lie. At every step, immigration agents and police have instigated the violence. There are no riots. People are protesting and blocking access to vulnerable people. LA is not on fire. These incidents are in very small geographic areas even though media would suggest it’s widespread.

People are pushing back when rubber bullets and tear gas are being used, illegally.

U.S. citizens have a right to protest. This is baked into our constitution.
