Blows my mind that 1:1 tutoring dwarfs the impact of other factors such as socioeconomic status, reinforcement, assigned homework, classroom morale, etc (at least according to the researchers).
Does anyone know if this thesis has been replicated? Or if these results hold in modern times (original study was 40 years ago)?
Seeing your launch hn made me happy. I tested one of your products in 2021. It's cool to see you and Parsagon working through iterations and finding customer traction. Mad props!
The author hits on a powerful point that is getting missed in this HN discussion. That is: talented and driven students are limited by the US education system.
Some of those young people cultivate skill by getting practice during youth. Doing that while young builds a compounding machine of personal interest + confidence + progress.
I have never seen broad data to support this, so discussions revolve around anecdotes[1]. That's fine by me though because we have countless examples of the legends of their craft who fit that mold: bill gates, zuck, warren buffett, taylor swift, mozart, da vinci... the list is long.
No single system will work for every single student. But that isn't the point. The point is that the best of the best deserve to feed their interests at a young age, which the current US upbringing limits. How many more bill gates and zuck-level creators could the world have if more talented youths could cultivate their talents very early in life?
>On February 7, 2024, Senator Scott Wiener introduced Senate Bill 1047 (SB-1047) – known as the Known as the Safe and Secure Innovation for Frontier Artificial Intelligence Systems Act (the Act) – into the California State Legislature. Aiming to regulate the development and use of advanced artificial intelligence (AI) models, the Act mandates developers to make certain safety determinations before training AI models, comply with various safety requirements, and report AI safety incidents. It further establishes the Frontier Model Division within the Department of Technology for oversight of these AI models and introduces civil penalties for violations of the Act.
The lack of data surprises me. It reads like the author has a vendetta against this brand.
They say that Air Jordans are “deflating” because auctions end at the low end of their estimated ranges, though still setting records for sneakers. All asset prices were inflated during zero-interest rate policy, and have fallen since then. What makes Air Jordans unique?
Showing sales data for Air Jordans would go further to making this point, and comparing that to Nike or sneaker sales overall, but they don’t offer that data or analysis.
Edit:
This site says that Jordan show sales were $6.6B in 2023, up 30% annually. This Atlantic write up seems misguided, if that data is accurate https://runrepeat.com/jordan-shoes-statistics
This article doesn’t address when cameras are blocked, which is the obvious issue with camera-only self driving. Teslas have crashed when cameras were blinded by the sun. Now throw in snow, rain, dust… Is that solvable with lots of cameras and different types? …Does it need to be solved?
Maybe the bigger question - anyone know the status of low cost lidar? Dozens of startups and larger companies were working on it 10 years ago, yet Lidar still costs “thousands” according to the article
These look like underground, single vehicle tunnels. It got me wondering why tunnels instead of building above ground. It looks like 1) tunnels are much less expensive in dense areas than above-ground roads, and 2) more tunnels can be added as needed by digging deeper (so the company says).
This is cool. I have no idea if they'll solve traffic jams or succeed as a business. There are many issues to solve (ventilation, safety exits, traffic from accidents and exit queuing, etc.). But, having lived in LA and seen how traffic alters livability of a region, I love that they're trying.
Reminds me of this quote "There are only two ways to make money in business: One is to bundle; the other is unbundle." - Marc Andreessen / Jim Barksdale
This reminds me of Thumbtack. Their customers, local service providers, are incentivized to move transactions off-platform to avoid paying commission fees (and taxes in many cases). However, those customers are willing to pay to connect to relevant leads, which seems to have worked out well for Thumbtack.
I'm a long time happy user. The site is fast, simple, and always seemed trustworthy in a market with seedy actors. You've helped me name multiple projects and companies - thank you!
