Comment Re:Taking CO2 out?? (Score 1) 375

the total system cost for an advanced nuclear energy facility to be $108 per megawatt-hour of electricity produced, compared with solar energy at $144 per MWh; and offshore wind at $221 per MWh. Onshore wind is less costly, at $86 per MWh, but it’s also less efficient. The estimated total system cost for natural gas plants varied widely, depending on the type, from a low of $65 per MWh to a high of $130. The variable costs for a natural gas plant are highly sensitive to fluctuations in fuel price, since fuel accounts for nearly 90 percent of its production cost. Fuel represents just 31 percent of a nuclear energy facility’s production cost, and the price is relatively stable.

Nuclear is cheaper than solar, off-shore wind, and middle-cost natural gas. Fossil-fuel-based steam turbines actually cost 46% more to operate, maintain, and fuel than nuclear; the up-front capital cost is higher for nuclear, though. Coal-fired plants can range $65 to $150 per MWh, so advanced nuclear facilities are actually cheaper than most of those. Nuclear is probably next-generation's base power.

Because herding cattle across a wide area requires managing a wide area. That means more cattle-hands, more moving from place to place, more expending fuel, more maintaining machines, more trying to extinct wolves for eating your cattle (estimate total population in Washington is 90), and, essentially, more wages paid per pound of beef, meaning more cost and higher prices at the grocery store.

I'd rather pay those wages to buy another month of Spotify than employ 40 fewer engineers at Spotify and 40 more ranchers herding cattle and not have anything to replace Spotify.

Actually, with excess nuclear power, we can produce eDiesel. We've got new catalysts and high-pressure processes making eDiesel highly-efficient, about 70%; that means pipelines fed from eDiesel plants placed near nuclear and geothermal power plants would come in slightly less-efficient than electric cars at 15% transmission loss and 85% charging efficiency.

We can stockpile eDiesel; we can use it for airplanes (no way to make those battery-powered); we can generate eMethane or otherwise use eDiesel to run fuel cells, creating liquid fuel electric cars (possibly airplanes, but it's a tough job for an electric motor); we can use it to drive factories which need more power than the grid provides.

Newer tweaks to battery technology are targeting high-surface-area electrodes. Lithium ion batteries grow tin whiskers internally, creating more surface area for reaction, thus higher and longer power output; current research targets new structures and new battery chemistries to maximize this, essentially attempting to create an activated-carbon-style surface as the battery consumes itself. The processes in eDiesel similarly use catalyzed hydrolysis, and it's non-consuming: if we can manufacture high-surface-area electrodes using current or improved catalysts, we can raise eDiesel efficiency. The two efforts are semi-parallel, in that efforts in one give insight to the other, yet they're distinct in significant ways and so can't directly translate.

That means more-efficient batteries and more-efficient eDiesel generation in the future. If the overall efficiency exceeds 85%, eDiesel will beat any electric vehicle: transmission loss is 15%. At the same time, low-cost eDiesel will immediately replace more-expensive petroleum, as it's compatible with current, unmodified gas turbine technology; and eDiesel can feed or be modified to feed hydrogen fuel cells, which provide electricity, giving a method of feeding electric vehicles with a liquid or heavy gas (not hydrogen, which has storage and transport issues) fuel tank rather than a battery.

At the same time, plant and atmospheric petroleum (e.g. eDiesel) products such as polyester, rayon, plastic, and lubricating oil (PAO, Group-3) will sequester oil. Recycling carries costs and complexity; cheap atmospheric petroleum, once expended, can be incinerated for power or dumped into expended oil wells. Deep well dumping provides an attractive option: the expended liquid petroleum becomes a feed stock for later mining and refining, while effectively removing the carbon content from the atmosphere.

This is all stuff that will happen naturally, eventually. eDiesel will scale; a reduction in cost of nuclear, geothermal, and solar will outcompete oil; and refining waste oil into recycled stock will be less-efficient than producing new oil at the point where atmospheric petroleum has become cheaper than oil. The only question is when.

People with high-meat-intake diets can, but rarely do, get deficiencies; people on vegan diets have to jump through hoops not to. That was the point: fruits and vegetables aren't the primary source of all nutrients, and aren't holding up your critically-deficient, mainly-meat diet; a cursory preponderance of evidence suggests the eggs consumed by ovolacto vegetarians are holding up their critically-deficient, mainly-vegetable diet. I've seen statistics stating between 75%-95% of vegetarians and vegans bail on the diet because of adverse health effects; and vegans themselves always have something to say about how you have to make sure you're eating the right vegan diet or else of course it will make you sick, which simply isn't a concern with modern incidental-vegetable-intake diets that get their main source of greens and yellows and reds from hamburger toppings and tacos.

CONCLUSION: Idiopathic constipation and its associated symptoms can be effectively reduced by stopping or even lowering the intake of dietary fiber.

The medical term "idiopathic" means "we don't know why," as opposed to being caused by an observed deficiency, disease, genetic condition, stress, or anything else. It's a placeholder for "healthy adults" when the adults are experiencing a symptom making them not healthy.

The benefits of a high-fiber diet have been repeated again and again, but rarely actually researched. Don't look too closely, or you'll find out you're wrong.

Eh, truth be told, if you want to grow more cattle on less land, you need to grow alfalfa densely and feed it to them. On the other hand, alfalfa and vetch are cover crops, and we grow them on our existing farmland between uses; we do use them as feed, or as fertilizer (plowed under before reseeding).

Is this another attempt to push a fruits-and-vegetables diet based on old superstition and ignorant observation? 400 years ago, nobody knew what micronutrients were; they knew if you didn't eat your fruits and vegetables, you got pellagra and scurvy--and you got pellagra by eating too much corn, too, so you needed to eat something else.

Today, somehow, people who eat diets with a lot of meat and don't overeat have few health problems. It's pretty simple: eat beef, eat chicken, eat fish, be healthy. There are a few micronutrients that are hard to get unless you're eating organ meats, certain fruits, or high-calorie shit like Hi-C fruit drinks--notably Vitamin C--but meat has a surprising amount of stuff like potassium and magnesium, so much so that you have to get into esoteric vegetables nobody eats to substantially beat the micronutrient profile of meat per calorie. There are only a few things an all-meat diet would leave you short on, and they're generally the things vegetables are actually pretty high in.

Has anyone noticed that meat-diets never produce deficiency diseases, yet someone is waiting in the wings to tell you you're doing vegan and vegetarian diets wrong because a lot of people get sick really fast on those diets? That's only counting malnutrition; things get weird when researchers do studies on constipated people and find out that a high- and moderate-fiber diet makes it worse, while a low-fiber diet improves things dramatically, and a no-fiber diet completely eliminates the issue--exactly what fiber isn't supposed to do.

So yeah, vegetarian diets are healthy--if you eat the right things, eat enough of them, eat massive amounts of them, and maybe take some supplements. Mainly-meat diets are healthy, if you don't eat too god damn much--honestly, Taco Bell and Burger King try to sell you 75% of a day's food as a so-called meal, so you're eating for two or three people by the end of the day, hence fast food making everyone fat (how did you think it happened?). They want us to go from the "you get fat if you eat too much" diet to the "you get pellagra and rickets if you don't diversify your nutrition correctly" diets (nobody gets scurvy; Vitamin C deficiency isn't a real thing anymore unless you try really, really hard).

That's actually a pretty complex argument.

Porting the drivers and such to a microkernel architecture in full (L4, Minix, Hurd) would isolate parts of the code and require strict API adherence (and ABI, but ABI amounts to your IPC protocol). That reduces the scope of bugs, in the long run; and it minimizes short-term porting bugs. The cost is essentially a large amount of man-power.

So you have the likelihood of finding a lot of bugs, eliminating a lot of bugs in the process, and creating new bugs, all at odds with each other, and each with different short- and long-term implications (you'll create new bugs in the short-term, but fewer than e.g. porting everything to BSD; and you'll eliminate and produce fewer bugs in the long-term); along with the enormous cost of simply organizing the change (everything has to be broken down and fixed around boundaries first).

The single short- and long-term advantage of keeping the Linux kernel architecture is it's a hell of a lot less work to not rearchitect an OS kernel.

Women are known to over-represent to PM. There was a phenomena for a while that women were shit for programming and other similar tasks, but always seemed to know everything that was going on around them--so they moved them out of their jobs and made them keep track of everyone else's jobs. When we started targeting formalized project management (PMI certifications and approaches), they only got better at it, somehow, for no reason known to me (I haven't looked too hard).

The end result is the big names in Project Management are Tres Roeder (Male, original proponent of Stakeholder Management) and Rita Mulcahy (female, dead, still considered the leader in PMI education); and many of the detailed books on project management processes and procedures are written by women. Men in project management have a large tendency to lean toward authority--they use older processes, repeat what's worked in the past (experience = authority), and bank on the understanding that they're in charge and that means something--while women seem to lean on processes and order, incorporating new ideas more-readily.

I have no idea why this happens, but it's a thing. There are flighty women who have no clue what's happening around them, and there are men who are actually serious about optimizing their approach to PM; but the general trend is women are more high-powered project managers, and men are largely sedentary and lean on processes they've used in the past coupled with the wielding of authority to demand people simply get shit done somehow.

Actually, if you're using a 94-element space (26 + 26 + 10 + 32), an 8-character password is on the same magnitude as a 26-element space (all lower-case letters) at 11 characters (7.2 x 10^15 vs 3.7 x 10^15). With a 1,000-element space, 5 characters (words) are on the same magnitude (1.0 x 10^15); although the 1,000-most-common words don't include conjugations and plurals, which takes you to several thousand. You have to breach a 5,700-element space for 4 characters to be on par (1.1 x 10^15).

So all-lower-case can actually be secure as the standard four-classes, eight-character password just by adding three characters. In all of these, we're looking at 50-53 bits (1.1 x 10^15 to 9.0 x 10^15) of entropy.

Seriously, the 8-character password with complexity requirements thing should have never come about. When they went from "8 characters" to "something more secure", it should have been 11 characters.

Systemd will be stripped as core functionality makes more sense as a kernel service than as kernel capabilities managed by a user program.
