Just a few days ago there was an article which claimed that Vitamin D supplements were useless (also referring to scientific research). Seriously, at some point, one starts not believing anything related to vitamins, since they seem to contradict one another all the time.


Supplemental vitamin D is not as effective as that naturally produced by exposing skin to the sun.

This is perhaps what you read, and doesn't invalidate thre findings here.


there is a saying, although very vulgar, "if you f* you will be loved if you love you will be f*d"


In my current company, we have a "calendar week" based schedule. Everything is planned based on that time segmentation principle. For example, "the start of production is planned for calendar week 45" - that is it, no month, no quarter no date - simply, the 45th week of the year.


it is kind of ironic that a country priding itself in data privacy was pushing for a very centralized data collection, while the "evil Apple" was pushing for a more decentralized and privacy-preserving approach.


hmm, I don't think you need to be a math genius to develop an intuitive feeling for it.


No, not at all. But to provide a mathematical basis and proof that can then be extended to all walks of life?


So, in the best-case scenario, there will be a mere 1.0degree Celcius increase and in the worst-case scenario, the average increase will be 6.5degree Celcius. I don't know how it is possible to model technological breakthroughs. I mean if we have a working Nuclear Fusion technology by 2100, that could drastically change everything - (almost) free energy = unlimited desalinated water = full aforestation, even in the desert areas.


The knock on effects from unlimited energy go a lot further.

We could use technology we have today for CO2 capture since it is heavily energy dependent and simply scale it massively. The bulk of industry processes that currently require coal, oil, or gas to provide cheap heat could be fully electrified. Prices of a lot of commodities would drop dramatically. Indoor farming would be a cinch. People and governments would abandon internal combustion for the cheaper alternative.

We could do absurd things that no one would even consider today like greening deserts as you mentioned or settling the arctic. You might be able to replace concrete with basalt if you could cleverly design a system for melting stone and casting the resulting lava in a form. Hell, you could banish winter by putting radiant heat in everything, walls, sidewalks, streets, and adding supplemental lighting like Moonlight Towers[0] except I suppose they would be Sunlight Towers in this case. The list goes on.

The world would change so much it would be like living through the first half of the 20th century again. From horses, coal, and brick buildings to jet aircraft, nuclear power, and glass skyscrapers.

Nuclear fusion won't be free energy at all. The plants will still cost money to build and operate. If you're only counting fuel cost, then solar and wind are already free energy. Even conventional nuclear fission is also almost free by that standard, and indeed people used to imagine it would be "too cheap to meter".


What is funny is the link reads as "google-reportedly-wants-to-be-top-two-player-in-cloud-by-2023.html"

Just searching Hacker news for "mars water" returns 200 results, dating back to 9 years ago. It seems NASA keeps "finding water" on Mars and then forgets about it.


NASA didn't write that headline...


that was meant to be a sarcastic remark


That is exactly what I wanted to say as well. It seems every other month, I see the exact the same title. At some point, it loses it becomes just another useless news


Solar Freaking Roadways! Do you guys remember this viral youtube viral video? https://www.youtube.com/watch?v=qlTA3rnpgzU


When I first saw that video I thought, “this has to be a joke right? They can’t actually think that is feasible.” And here we are…


The video attracted so much undeserved attention that many engineers felt that they had to produce a corresponding debunk video explaining why it is such a useless idea and why asphalt is currently our best option on building roads.
