Osiris30··on How I learned to code in my 30s
Would you know, or can recommend, any good datasets (or practice exercises) using "Jupyter/Python/NumPy/Pandas/Seaborn" for someone with a similar Excel background (and basic understanding of Jupyter/Python/Pandas)?
Osiris30··on Are China and the United States Headed for War?
See previous HN discussion on China and the 'Thucydides trap' (2015) [1]

And also - "There is no Thucydides trap' - an essay/review of Graham Allison's book by Chinese history scholar Arthur Waldron - "In this book review, he argues persuasively against a concept that has become a pillar of establishment thinking on China." [2]

Agreed. See this video "Bruce Bugbee, Utah State University Department of Plants, Soils and Climate, has studied plant growth in controlled environments for most of his career. Here he presents the results of his analysis of the environmental effects of Vertical Farming/Indoor Agriculture (September 2015)"

Osiris30··on Raising the American Weakling
But neither is loading 3x your bodyweight onto your spine "natural". What does "universally accepted as one of the best natural movements" mean? - As you suggested to the previous comment, please "Provide some data or get out of here".

It all depends on your objective and goals. As with everything moderation is key. A balanced program of squats, deads, pushing exercise (chest/pecs) and a pulling (back/delts) is best for oevrall muscle, bone and tendon health. Whether you do this via free weights, body weight, or machines is really not material.

Rippetoe style heavy free-weight squats, squats and more squats is not the be all and end all of resistance training. Personally, I got into heavy strength training with Rippetoe's books and videos - and, IMHO, he did a great service by educating people about the benefits of heavy (free weight) strength training using a very very simple ('KISS') type program (at a time when the focus was on machines and overly complicated routines). His routines are great for beginners - especially very young ones - hence why they are copied and 're-mixed' so much (like Stronglifts 5x5 and countless variations thereof).

And I would really not suggest heavy squats for improving grip strength - that would be a very inefficient way to train your hand grip.

Osiris30··on Opendoor, a startup worth emulating
It's not that it is 'benevolent' - I think the article was making the point that what OD is trying to do is harder, and socially more beneficial, than just matching demand & supply using an online service/app (like Uber, Airbnb, RedFin. etc).

The service OD is providing is liquidity - and the risk they are taking, which they are compensated for, is liquidity risk. This is what 'market making' is - you stand ready to buy & sell and create efficient market.

Beyond the 'data science' of pricing the property, and the tech of automated visits, - the main operational task would be to build an efficient market making business. Anyone who has spent any time in a bank trading desk would know how difficult this is. In a rising market - volumes and upward pricing and demand all tend to go hand in hand - the real test, will be when when the market turns - and maintaining liquidity (and a thin 'bid-ask' spread) in a falling market.

Someoned use the analogy of London trading houses... Another good analogy would be what Marc Rich (and others) did in the 1970s when the broke open the oil market - which had been dominated by long-term contracts - into a more liquid 'spot market'. OD is trying to create a liquid, 'spot market' for a previously illiquid market.

OF course - the market which need the most liquidity (ie the ones outside the 4-5 main metros) is where providing liquidity will also be the hardest. Unlike bonds, shares and oil - housing is not 'fungible' (for one, you can't move a house).

Sounds like a difficult but valuable enterprise - good luck to you and your team.

Osiris30··on Facebook admits it must do more to stop the spread of misinformation
"It’s totally forgotten now, but for the 100 years after the American Revolution, the U.S. government made it free or almost free to send newspapers anywhere by mail. It was available to papers of all political perspectives, with no government censorship. The rationale was straightforward: This was necessary for people to participate in governing themselves."
