The biggest question I have is why does it take 47 years to upgrade trains in one of the richest cities in one of the richest countries in the world?

Relevant thread - question asked by Ramez Naam on the feasibility of Prometheus:

What about the effects of 'time spent on the problem' (ie compounding)? If you are only learning for learning sake, then getting to a "101" or "102" or "103" (to use American college level terminology)is fine I would assume. This might take 1-3 years of learning/study/doing.

But if you truly want to "master" something - then does "constantly thinking about problems" mean you will never benefit from the same 'compounding' effect as someone who has spent 3/5/10 years of their time on that problem?

Or - is all your "need for cognition" - mostly in one domain space (e.g. "Computer Science" or "database structure" etc)?

Also see previous recent discussion of indoor/vertical farming (2017) - (1) and (2).

As discussed on that thread, vertical/indoor farming is great for leafy greens (mainly water but but not much other nutrients or carbon), but much harder for other plants.

See this video [3] - "Why Vertical Farming Won't Save the Planet: 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)".

Seems aimilar to the Swiss startup Mindmaze - 2016 Intro article after their initial fundraise https://www.forbes.com/sites/aarontilley/2016/02/17/mindmaze...

And a more recent Wired article https://www.wired.co.uk/article/mind-maze-virtual-reality-br...

Yes please do write a detailed blog post on this.

CBW Bank - founded by an-Ex google engineer and an ex-Wall Streeter has been doing this (created a bank from bottom Up - including purchasing an actual bank and creating the software) geared towards startups) since 2014. Don’t know how well they are doing now.

But they wouldn’t have had the in-built In go-to-market strategy, or the prestige/visibility in the funding community, of a YC Alum.

Not being harsh to the OSSU team - they've done a great job and hopefully they can comment on this - but I prefer TeachYourSelfCS. - Because (a) they provide both Book AND Video/MOOC resource for each topic and (b) its a lot more apparent what the 'core' knowledge you need to attain to get a solid undergrad level knowledge base is.

I also like this resource site - its a bit dated though: http://blog.agupieware.com/2014/05/online-learning-bachelors...

Also would be nice to get a simple roadmap like this https://roadmap.sh/frontend

Interesting. Could you elaborate further on how you do this, study techniques for “meta learning” and what you define by “blowing through”? Thanks

There’s wikiversity - https://en.wikiversity.org on all of different topics.

And several others are trying to create mind maps.

But would be great to have a resource like OSSCSU or TeachYourSelfCS for X...

At least for the “main” subjects like Maths, Stats, Chem, Bio, Physics and Humanities - Econ, Anthro, Pschy, Pol Sci, Law, Sociology.

Short thread commentary on the paper by Ric Fulop (co-founder of A123 battery co. and current CEO/founder of Desktop Metal): https://twitter.com/ricfulop/status/1170527207657263104

Would this be a correct summary of the paper?

1) eliminates Cobalt

2) improves energy density (more range)

3) faster charge rate

4) less SOC (state of charge) swing, meaning less cost & weight

4) 5x longer lifespan

The author Seamus Blackley is also a co-founder if the XBox amongst other cool things https://en.m.wikipedia.org/wiki/Seamus_Blackley

Count me in too

Do you have any good recommendations for books, textbooks, links, lectures or papers for beginners to start to understand this area?

As a counter, see the previous discussion on Kevin Kelly - the AI Cargo Cult & the myth of a Superhuman AI (1).

See also several other articles making similar points (2).

And "In late 2008, economist Robin Hanson and AI theorist Eliezer Yudkowsky conducted an online debate about the future of artificial intelligence, and in particular about whether generally intelligent AIs will be able to improve their own capabilities very quickly (a.k.a. “foom”)."

Interesting. Do you have a link for this?

If you have not done so already, (and for many others commenting on this thread), in your situation you might get a lot out looking up "The Sinclair Method"; "Dr. David Sinclair" and "Pharmacological Extinction". Some useful links below.

Dan Shiffman's youtube channel "The Coding Train", his books and website - are really great introductions/tutorials to general programming, creative programming, natural language analysis, machine learning and a whole bunch of other topics. He has this ability to make technical-sounding (or actually technical) concepts and projects interesting, non-scary for beginners (and non-math background people) and fun. In my view - his books & videos are prolly the best introductions to programming for kids and people who have a fear of programming.

If you read the various blog posts and interviews - the history of Processing at his department (NYU Tisch ITP) had a purpose of encouraging 'creative' people to explore and gain an exposure to programming.

All link to above can be found on his personal site - http://shiffman.net/

See the previous discussion on HN - "recraiglist" and "They Used To Last 50 Years" (1) - a well-circulated blog post by a successful used home appliance repair & trading entrepreneur.
