You need to include the cost of battery storage to wind and solar to get a true apples to apples comparison. Comparing the cost of unreliable energy with reliable energy is like comparing the price of a high risk bond with a risk-free bond.

Breeder reactors can create more fuel, but even without these, there is a substantial amount of uranium that this is a non-issue. By the same token, solar is also non-renewable since it requires real resources mined from the earth which are

Yeah, I'm a supporter of Nordstream 2 because cheap gas is better than expensive gas, but I can't understand why Germany is making itself more dependent on gas instead of building out nuclear capacity to be less dependent. The w

There is a long history of marxist groups trying to destroy the family by forcibly removing children and making them live in various communal camps. For example this was done in forced collectivization projects in the USSR and China, and al

As someone who has been in this field professionally for almost 20 years, my thoughts on this have changed quite a bit. The idea of condemning security through obscurity traces back to cryptography, not security in general. In cryptography,

HN removed a leading "how", which in this case hurt the title. It's a fascinating research article -- the link itself is just a few paragraphs but it links to the full paper which is free!

Yes, just based on that it should go up, but there's a huge difference about it increasing at 0.5% per annum and 1.5% per annum, and it's not going to go up monotonically, which is the difference between your long run graph and

FYI, (non-farm) Labor productivity declined by 5.2% year over year: https://www.bls.gov/news.release/prod2.t02.htm If you break these numbers down, you see that total production increased by 1.2%, but it required 7.4%

Yeah, having a job increases your negotiating leverage and only gives you more options.

That's fine and I'm all for new theories and new models, but let's let them actually make it into the IPCC and see how they are peer reviewed, how the findings are reproduced and assessed by other scientists, etc, especially

IPCC v5 is predicting .3 to 0.6 meters of sea level rise by 2100. That's about 1-2 feet over the next 80 years. Maybe we can stop with the extremism, especially for something as well measured as sea-level.

That's a question about philosophy, not real things existing. I mean, it's not going to be settled as a matter of fact, it's a matter of opinion. But if you are asking for my beliefs, then no, rights are downstream of duties.

I don't think you can make simple rules like this, or expect complex systems like economies to behave according to such simple rules. What you can know is that in expensive areas, they will need to pay a premium, but does the premium n

For the same reason, I'm not so absolutist about DRY. Having the most elegant codebase also often means the codebase that's hardest to work on, and it's often better to clean things up afterwards once you know how things will
