Dancing. I was both horrible at it and or disaster happened when doing it* so I became 'too cool' to dance.

One New Year's I finally had a girlfriend I could be authentic with, we were at the city's 'First Night' party, so different activities all over town, and I told her 'I really want to go dance to the big band in the grand ballroom. But I am a horrible dancer and every woman I have danced with has made fun of me'. She was down, was patient, and it was one of the most fun nights of my life. After that we started taking salsa lessons. So just dance. And if the people you are with make fun of you, don't stop dancing, stop being with those people.

* Example: Junior prom, slow dancing with my date in her fancy dress with her $200 hairdo. The gum I was chewing (because I took her out to sushi, which she informed me was gross, and therefore would not kiss me until I got the taste out of my mouth) somehow attached to a hair of hers in my mouth. Before I could unstick it she flicked her hair, yanking the gum from my mouth and into the rest of her long hair. Fun times were not had by all.

How much time do you allow passing before each recontact?

Around 3 days.

That sounds a bit too pushy for me. I would expect at least two weeks before recontacting.

The quote below is from a 1995 interview with Steve Jobs. Forgive the length, but the whole thing is quite poignant and there wasn’t much to be trimmed. This particular interview confirmed my own experiences with esoteric processes that people do just because that’s how it’s always been done, and the opportunities that exist because of it. ———————— You know, throughout my years in business I discovered something. I w…

Agreed with this. One thing I've learned about large established companies is there is a lot of room to deliver impact if you can rework inefficient processes and navigate the politics to have that change adopted.

Steve was fortunate in that he could do whatever he wanted which isn't always the case for everyone else.

This is what made it click for me, can recommend it: 3Blue1Brown -- But what is the Fourier Transform? A visual introduction. https://www.youtube.com/watch?v=spUNpyF58BY

That video did the same for me. I also like the reducible video for Fast Fourier Transforms as well as the Veratasium piece that shares some fun history. Reducible - FFTs the most ingenious algorithm ever https://youtu.be/h7apO7q16V0 Veritasium - The Most Important Algorithm of All Time https://youtu.be/nmgFG7PUHfo

The FFT is something I still can't quite grok, for some reason.

Your original claim was much broader: > despite their ambitions the BIPOC people I know haven’t been able to reap any professional benefits from it

because they didn't need the MBA for the roles they did land its all part of one contiguous complete thought

You also say:

> the connections resulted in no improved professional access or ability to exchange time for food and shelter.

When you make such broad statements, then walk them back in comments downstream, it makes conversation unfruitful.

People never change because of YOU. This applies to work, relationship and family. It made me click about the saying that science advances one funeral at a time. It is easier to rally people of similar thought than to change people of opposite opinion. Not impossible, just more difficult. It explains a lot of thing in my opinion. 1. It is easier to start a start up than to convince your boss to take a certain product…

Yes, that resonates. But how do people change? Through their own rude awakenings? When they contrast their own selected peer group with other teams?

As a white guy, I'd certainly encourage you not to worry about this -- if we're talking about an upper middle class, professional-ish activity, you can be fairly sure that all those white people feel self-conscious about their group being so white and would welcome you to join them. Anyway, I'd be interested to hear more about the psychology of this. I remember when I was growing up in the 90s and 00s in California,…

I've heard similar things, but as a non-minority, you don't see what happens when you aren't looking or when people think they can get…

>You might be well-intentioned and surrounded by people who you believe are well-intentioned, but not everyone is, and plenty of the people who talk and act as if they're well-intentioned will turn around and betray those purported intentions when you aren't paying attention.

Yeah I totally buy that.

>With regard to race-blindness in the 90s and 00s, consider that today's focus on race is a reaction to the willful ignorance of the decades prior. Race mattered just as much back then as it does now, it's just that the majority in the past had patted themselves on the back and convinced themselves that it was a solved problem if they just stop talking about it.

If we believe racial discrimination is the root cause of racial inequality, then "talk about race less" (as a way to treat people more equally, and reduce discrimination) seems like a reasonable hypothesis to test. So the thing about people patting themselves on the back seems perhaps overly cynical?

I'm also not convinced that what we're doing now is working better than what was done in the 90s and 00s. For example, this Gallup poll indicates that Black adults believe race relations with white people have gotten much worse since 2013: https://news.gallup.com/poll/1687/race-relations.aspx

And I've seen research indicating that corporate bias reduction trainings typically backfire. Apparently if you want your company to have more diverse leadership, one of the most effective ways to do that is to create an official mentorship program which randomly pairs off junior people and senior people without regard to race. It seems that a junior employee of color gets better mentorship if they are regarded as a "junior employee at our company" as opposed to "junior employee of color". The mentorship program just works to overcome activation energy and create relationships between junior and senior people which might otherwise not exist due to awkwardness. (This is all from Chapter 8 of the book Meltdown: Why Our Systems Fail and What We Can Do About It)

The output of the 90s and 00s era was Obama getting elected president in 2008 and serving two terms. By contrast, I do think you can make the argument that Trump is in some sense a product of the woke era.

Trump's popularity exploded around July 2015: https://www.realclearpolitics.com/epolls/2016/president/us/2...

But e.g. the number of NY Times articles on "whiteness" were on an exploding trend by 2014: https://marginalrevolution.com/marginalrevolution/2019/06/th...

(The number of articles with those terms grows even faster after Trump becomes popular. I would postulate that the mechanism is something like this game I linked elsewhere in the thread https://ncase.itch.io/wbwwb )

Anyway, my impression from reading right-wing Twitter feeds is that supposed woke overreach is a major motivation for Trump supporters, playing into the backfire point I mentioned previously.

I'm sure there is room to improve on the 90s and 00s. But I remain skeptical of the politician's syllogism: "We must do something. This is something. Therefore, we must do this."

Learning history / literature in school is important. I was a total STEM math nerd in school. I used to frequently complain how I don't get what's the point of it, or how it's a waste of time and I'm learning nothing. I still think the emphasis of school was off, but I get the point of it now. Stories are like code for humans. You can't tell someone what it means to be good or bad, or to give them a course in philoso…

Additionally, I would say more historical emphasis within STEM itself would be beneficial. Motivate through context. Show students that the concepts arose from people solving problems.

One of the biggest realizations recently for me was realizing that a nearly all of software development is basically about turning a slow, manual process into a faster, automated process. Modern CI/CD stems from a bunch of shell commands that somebody wrote and manually executed to test an app and upload it to a server. Modern automated software testing stems from humans writing small test apps and running them to co…

This is a great way to understand complex, new-fangled technologies. Ask "what manual process does this speed up"?

Okay, I'll bite:

What manual process does ChatGPT speed up?

• Basic concepts of dynamic programming and precomputation.

During lockdown I attended a course that prepared students for IOI. I couldn't focus/follow at home via web conferencing. One year after I attended some lectures from the same course, but physically. I understood everything when it was explained in person.

• Basic concept of buckets in distributed hash tables. After reading BEP-0005 I was left puzzled and left the topic for some months. Reading a Wikipedia article about Kademila, first understanding static buckets and transferring this to dynamic buckets with splitting was way easier to grasp.
