Take any of these videos with a grain of salt.

In demos these robots only need to do well once and it can take hours to record.

In real life, a failure rate of 80% is unnacceptable, but perfectly fine to edit out in the final cut media.

I hope they do well, this area is incredibly hard, but it will take a lot more than what people imagine.

I just want the consumer grade robot dog so I can program it to chase the roomba around.

This whole hype cycle man. It's all shiny demos and no real products.

Robotics is hard and robotics companies fold as fast as flies die on a hot summer day.

I am not suggesting it is easy. I am saying, it is a lot more likely now than 10 years ago.

I believe some problems in the field are now easier, we haven't made a dent on the truly hard ones, IMO.

source: I work in the field.

I am not in the field, but I am trying to branch out a little so it helps to talk with someone who is.

LLMs probably help the same way they help with other stuff. They lower the barrier of entry for newcomers ( good and bad at the same time ).

That said, what are the current hard problems? I don't want to derail the thread, but this is of personal interest.

Gmail's +tag (and the .) is nice in theory, but terrible in practice. It's super easy for malicious actors to just drop them and there are a few services out there that simply are not able to work with the +tag, potentially getting you locked you out of your own account. Not gmail's fault, but I would recommend against using it.

Mine is "leadership sync":

If you ever worked in a dysfunctional org this video speaks volumes.

These are all great, and for me it's even weird to pick a favorite because somehow he's managed to put so much genius into all of those videos and in so many multifaceted ways, it's beyond me. What kind of job/career experience has he had to come up with all of that, so creatively and accurately?

I just don't get how he can have had all this experience and at the same time be able to come up with those creative videos while still holding those insights. Because there's so many clever little things implying he's seen a lot. And created those videos in parallel.

> What kind of job/career experience has he had to come up with all of that, so creatively and accurately?

One of them has been at Amazon for a while.

Seems like an accurate set of experiences of a 10-20 years long career.

this signal the death of the passive aggressive "take this offline" for me

also favorite comment "This video captures the absolute weirdness of millennials and zoomers inheriting the bureaucratic systems created by baby boomers"

I find it weird how so much generation discussion seems to skip gen x. I see references to boomer, millennial, and zoomer/gen z way way more often than gen x.

Gen X’s arc was going from Reality Bites/Wayne’s World slacker grunge culture into the stultifying white collar Office Space of the Matrix and then disappearing from the zeitgeist entirely after 9/11 made Fight Club’s ending sort of real.

As a Genuine Millennial (1986) who works around a lot of Gen X, I don't really perceive much of a difference between us tbh.

We are the "meh" generation -- I'm happy we're overlooked.

Nothing, but buckle up, we need to refactor our stack again.

Cynism and burnout, but if you are in a dysfunctional it's hard to move away from that either way.

I would argue that the problem is maintenance. Trees need to be pruned, watered, checked for pests, can get into sewer lines, waterways, etc. To sum up, they require work and one thing that governments hate is extra work.

Yet municipalities never seem upset by all the future maintenance required when they allow new subdivisions with roads, sewer, water infrastructure to support in perpetuity.

I would argue that it's not so much that governments dislike extra work but rather that the populace dislikes the additional tax expenditures that accompany it.

Startups must choose between doing things

- Cheap - Well - Fast

Choose two.

You can get all three if you don't let project managers take over.

Good leadership of a small skilled team gets you powerful results.

I think that means they aren't cheap.

It's a different kind of cheap. A high functioning team costs what it costs. Until you break it.

Once you become more interested in power than success then the high functioning team becomes the enemy because you can't control them.

we cant have high functioning teams because ultimately they wont scale. so we have to settle for just not functioning at all, because thats where we're going to end up anyways. right?

As a project grows so does specialization. You can grow the team until it becomes unwieldy, then split it into to around people who are facilitating keeping that culture. It’s helpful to have teams of teams and a few members who transfer between them to both keep the culture from bifurcating and to reduce Us and Them.

The people aren't cheap but you can do more with less. Having one expensive competent engineer is cheaper than four bad ones and a PM.

I can always easily burn extra money to spend more for the same thing.

But that doesn't really tell me anything about how to hire competent people who can build things fast for cheap.

What I'm getting at is "just hire extremely competent people" isn't really a way out of the original statement.

Pick 2 (fast, cheap good).

Indeed, please write an algorithm to reverse a linked list in O(1).

Assuming I can choose linked list implementation, that is trivial:

It's a doubly linked list where the head contains a pointer to the tail, and a flag that determines which pointer in the nodes is forward and which is backward.

It's a trick question. Ask if its on Space or Time complexity ;-)

Has Youtube been completely moved off from Python? Last account I have from it (quite outdated, I must admit) was that it had heavy ties with it.

Not sure, but I believe the performance-critical components are C++.
