In that case the question is why did they use hydraulics in the first place.

Static holds. Once you pressurize the cylinder to make it move to a certain position, it can hold that position without using more energy.

This makes sense for quasi-static systems but obviously is a limiting factor for dynamic robots.


Anyone got a tldr?

It's the Lean Startup Method but in course form.

today we’re proud to unveil Product-Market Fit Method, an intensive 14-week experience designed to help exceptional pre-seed founders build epic B2B SaaS companies.

But that would only make sense if most people lived in a line city.

There are much more effective ways to achieve population control than building line cities and moving people into them.


Because TikTok can be used as a weapon by China. Democracies have a weakness - enemies can influence the population and therefore the government. Russia does this quite effectively in my opinion (one example is Slovakia).


Social media of US owned companies was already used as a weapon and still is. Perhaps instead of this legislation we should clearly lay out the regulations that all social media companies need to adhere too.


Social media can and is already being used as a weapon by internal actors against democracy.


I've been eating quite a lot of sugar all my life and in general I eat when I'm hungry until I'm not hungry. But my BMI is 18.5 and fat 11% (per my scale, probably inaccurate). How could this be possible? Maybe small stomach?


Genes. It's most likely not the stomach but the hypothalamus. It basically controls hunger and some people's hypothalamus is really good at defending against weight gain, and other aren't.


My auntie could eat a lot and was always super thin. Then she turned 50 and her metabolism stopped keeping up and gained a lot of weight.

Saw the same happening with someone turning 25, super thin athletic body into gut over the course of 2 years, diet was the same for 5 years.


What's your estimate of how much does it increase a typical programmer's productivity?


Interesting that he didn't say why he left. He says "my immediate plan is..." meaning that he has no specific long-term plans or doesn't want to talk about them.


You don’t expect people at certain levels splurging out their plans to populace, do you?


Yes.


Is roughly this level of sophistication enough to beat the S&P 500?


Is the market really that dumb? I'm increasingly thinking about becoming an active investor.


Sophisticated money is generally not. The average retail investor absolutely is. Most retail investors invest based on emotion not on fact. A lot of tech company employees justify their emotions as providing them an edge because they're in the industry, but they often likewise get hung up on factors that they find emotionally relevant but aren't actually market relevant factors.

Look at this other comment https://news.ycombinator.com/item?id=39222007 in this thread. A lot of it is just idle speculation based on the commenter's personal values. These are the analyses that drive retail investors to invest. I don't mean to pick on this commenter specifically; I just felt it to be very illustrative of the kind of analysis that the average tech person does to justify or not justify an investment.


“Techies aren’t as smart as they think they are” is always something that I’ll happily get behind.


I think we're plenty smart for real.

But where we go wrong is thinking that our tech smarts translate to other fields like finance.

Personally I know it's one of my weak spots so I stay far far from investments.


The question is how smart is the break-even investor, i.e. the person I have to beat to win in this game.


Investing is about reading the facts, not the tea leaves. Sometimes the facts aren't enough to predict the future. See Bill Ackman trying to catch Netflix falling and exiting at a loss soon after: https://variety.com/2022/digital/news/bill-ackman-sells-netf...


Had a decade ago you bought and held the FAMNG index of companies, you would have beat pretty much every hedge fund and active manager, save for Renaissance Technologies....


Hindsight is 20-20 though. If you had bought Apple at the trough, you would have done fabulously well.

That would make it harder to make money with this project if it becomes successful in the future.


I think that's what the parent is saying. Are the site's users unpaid labor? That was a thing corporations tried to do when back when urban dictionary was starting, but in today's climate working for a corporation for free doesn't have the cachet it used to.

This may actually be a feature, not a bug.
