khallow Re:Weakest US President ever (565 comments)

You really don't know your history if you think that WWII happened because "the world didn't have the balls to stop German and Japanese aggression when it would have been easy". WWI was still fresh in the minds of the people, the great depression was in full swing, Germany was not aggressive, Japan was still (for the most part) keeping to its self.

The obvious counter is that Germany was aggressive (both with a vast military buildup and multiple invasions and forced annexations before the Second World War officially began) and Japan was not keeping to itself (such as their invasions of Korea and China and their well-telegraphed war with the US and the UK).

And a military push by France in 1936 to reverse the remilitarization of the Rhine, would have been pretty easy. But having said that, it would be easy to underestimate Nazi Germany in 1936. They had over the course of a few years rebuilt a world-class military from the stunted post-Versailles remnants. I believe the Second World War would have been easy to prevent in 1936 or 1937, but I also believe that it wasn't that clear what course to take.

Still when one looks at the bizarre things that France did, such as building a vast and expensive defensive network of fortresses (the Maginot line), but not actually defending against the invasion path taken in the previous war (and which Nazi Germany used again), it's painfully clear that they weren't making good decisions even given the uncertainty of the times.

Now, though, I'd say that the people who will use the opportunity will be the ones like Strelkov and Borodai

And do what? They have no power base outside of the Ukraine. And a few thousand "battle-hardened fighters" won't make much of a difference politically or militarily.

I'd look rather at the people surrounding Putin or domestic unrest.

Self defense is not "in anger."

Actually, it is a case of "in anger". The term has nothing to do with anyone's emotional state or any particular defense/offense scenario under which they might find themselves. "Used in anger" with respect to a weapon means that the weapon is being used as designed with intent to kill someone.

Suddenly Visible: Illicit Drugs As Part of Silicon Valley Culture

khallow Re:I love the little mitigatory clause in there (505 comments)

It means that those Silicon Valley workers can fund their drug habit. The high stress part is motive. The high pay part is opportunity.

Report: Nuclear Plants Should Focus On Risks Posed By External Events

khallow Re:Stylized (125 comments)

mdsolar indicates that he is referring to some estimate rate of 1 such accident in several million. But that sounds like a theoretical rate for a limited class of failure modes under ideal maintenance and regulation conditions. Can't say any more about that until I find out what he's speaking of.

Greenpeace: Amazon Fire Burns More Coal and Gas Than It Should

khallow Re:Hipsterism at its finest (worst?) (287 comments)

Power consumption is proportional to usage, plus a constant.

But that is the case whether one downloads the music or buys a SD. The latter requires actual movement of physical objects, which I think is more costly relatively speaking.

Report: Nuclear Plants Should Focus On Risks Posed By External Events

khallow Re:Stylized (125 comments)

Ok, where's the reference then?

I see when I googled, an estimate for "large" "loss of coolant accidents" around 5*10^-6 per year per plant. That sounds like your number. It's worth noting that the accident category in question hasn't happened yet since they're speaking of loss of coolant from pipe corrosion and mechanical failure in a plant with proper maintenance and the following of procedures, not the many other sorts of loss of coolant accidents that can happen to a nuclear plant (such as the real world examples caused by earthquakes, incompetence, and poor maintenance).

Report: Nuclear Plants Should Focus On Risks Posed By External Events

khallow Re:Stylized (125 comments)

mdsolar stated that the NRC estimated the odds of a "nuclear accident" at 1 in 10,000 and then claimed that such accidents occurred at a frequency of 1 every 18 years. What I noted is that there are 435 reactors currently (according to Wikipedia) and that accident rate he claims corresponds to one such accident per 8,000 years of operation of the nuclear reactor. That is very much in line with the estimate.

This has nothing to do with "nuclear FUD websites". This is just rudimentary statistics.

Report: Nuclear Plants Should Focus On Risks Posed By External Events

khallow Re:Stylized (125 comments)

18 years*435 current reactors=7830 reactor years. Which is close to the claimed 10,000 reactor years of your original post.

No, otherwise you wouldn't have written:

It really harms the credibility of the NRC when their risk calculation come to a accident every ten thousand years while the real world rate is one every 18 years.

Greenpeace: Amazon Fire Burns More Coal and Gas Than It Should

khallow Re:Hipsterism at its finest (worst?) (287 comments)

I don't know how much energy it takes to build, ship and operate an SD card - but it doesn't sound implausible that it could save as much or more over the course of a three-year usage life. People listen to a lot of music on their phones - how much power is taken to stream some music for a hour's commuting five days a week/

So they have to stream the music at least once in order for it to get to the SD card. That implies the existence of all that power consuming infrastructure, whether or not it gets used to stream music 5 days a week.

Greenpeace: Amazon Fire Burns More Coal and Gas Than It Should

khallow Re: Clever editors. (287 comments)

According to wikipedia, Nigeria puts out less CO2 than 42 other countries, while China, the US, the EU, India, and Russia top the list in that order. I'm willing to bet that Nigerians also probably aren't particularly high-carbon emissions per capita compared to people in my country, the United States.

But this is all a bit much because you probably don't really want to control the population of the biggest CO2 emitters, do you?

The thing is, he doesn't have to think about it. India is the only country on your list that doesn't have a native population with fertility at or below replacement rate.

khallow Re:Hipsterism at its finest (worst?) (287 comments)

Is it cheaper and or greener for me, a single person to store my single photo on a SD card or on a file server.

File server is clearly better in that case because it can store a lot of other peoples' single photos too while you're wasting a whole SD card on one user. The file server is somewhat more resources consumed than that SD card, but those resources are split over a large number of people, while the SD card only supports one person. That's not even getting to the functionality aspect.

khallow Re:It's a shame (287 comments)

Government regulations on energy production are the only thing that's keeping the US from looking like China.

In what ways? Obviously, we're not choking on high levels of smog. But neither are we enjoying the fruits of economic success compared to China. Regulation is responsible for both the cleaner environment and the killing of the economic golden goose.

khallow Re:It's a shame (287 comments)

but if you suggest any lifestyle changes they immediately dismiss the idea without accepting that supporting the environment might mean some small compromises.

Three common problems with these "small compromises" is that a) the proposer is often entirely clueless about the issue, b) the "compromises" aren't small, and c) they often don't actually do anything for the environment.

Considering your example of the SUV driver, why should their need to prove their manliness be less important than your feelings about the environment? Merely, being slightly more polluting than alternatives is not IMHO compelling.

Cheap airship sets new record for altitude

khallow khallow writes  |  more than 2 years ago

khallow writes "Last weekend, we saw balloons beat records for the highest amateur balloon and longest latex balloon flight by distance and duration, but another record was broken as well. JP Aerospace, a team operating out of Sacramento, California (but supported by members all over the world) launched an operating airship to 95,085 feet (almost 29 kilometers high). Space.com had this to say:



Crewed stations floating high above the Earth with huge balloons could someday act as waypoints for human astronauts headed into space. That's the vision of a DIY space program that has smashed world altitude records by sending a drone airship flying up 18 miles into the sky. The Tandem airship soared almost four miles higher than any past airships during its record-breaking flight on the morning of Oct. 22. Its flight to 95,085 feet above Nevada's Black Rock desert marks a first step toward plans for an "Airship to Orbit" program that would fly humans into space using existing technology.

"The big aerospace firms have been trying to do this for decades, spending hundreds of millions of dollars," said John Powell, president of JP Aerospace. "We've spent about $30,000 and the past five years developing Tandem."
