Comment Re:What's changed? (Score 3, Interesting) 154

The problem is that social media reduces us to the way we present ourselves. While that certainly is part of who we are, it's not the whole story.

One of the most popular maxims of ancient Greek philosophers was "know thyself", and the reason they considered it important is that it turns out to be a lot harder than it sounds. You think you know yourself, but chances people who spend a lot of time in close physical proximity to you understand you in ways you don't.

But online your identity is mediated by how you present yourself. This is not only inevitably somewhat dishonest (in ways that may be more obvious to others than to yourself), even when you are trying to be honest you at best are presenting who you think you are.

Comment Re:"The science is settled" (Score 2) 56

Some of the science is settled, certainly. Methane is a greenhouse gas; nobody expects that to change. Atmospheric methane decays primarily through a long, well-documented chain of reactions starting with oxidation by the hydroxyl radical; the carbon in the CH4 eventually ends up in a CO2 molecule. This is nothing new, and nobody expects it to change.

The precise dynamics by which CH4 interacts with hydroxyl radicals in the atmosphere is far from settled science, and nobody should be particularly surprised that there are things about the process we don't know. Not knowing some things about a process doesn't mean we can't know other things about that process.

But some people obviously do believe it means that. They do not distinguish between not knowing everything and knowing nothing. Implicitly requiring scientists to know everything before you consider science credible makes everything a matter of opinion, and all opinions more or less equally valid, at least as far is evidence is concerned. And it's easy to see the attraction: if everything is a matter of opinion you can believe whatever you find comforting. Why not believe Adam and Eve rode around on dinosaurs? After all scientists don't know everything, which means science is never "settled".

But of course settling questions with evidence is what science is all about. True, there is no science so settled it cannot be attacked; but there *is* science sufficiently settled that claims to the contrary require extraordinary evidence.

Comment Re:I believe it (Score 1) 71

I've been saying this for years: the reason that the same stupid security holes keep popping up is that they keep showing up in the tutorials that people use to learn new systems and languages.

The cognitive burden of learning a new system is rough on most people, so it's tempting to make things easy on them. In fact you might have higher satisfaction from students if you do. It certainly makes them feel like they're learning more for less effort if they can make something happen that looks right. But you should never, ever model a bad practice for beginners, even if you have the intent of going back and explaining to them that they shouldn't do it that way. It's better to say, "OK, you don't understand this particular bit, but don't worry I'll come back to it later."

I suspect this may enable them to lower their prices or increase their margins.

Linux support on popular high-end hardware is close to flawless -- or becomes so after that hardware has been out for a year or so. But if you start looking at the plethora of low end laptops, especially, you are in for a world of minor headaches. I find it takes me about a week of research to get a cheap, relatively new laptop working flawlessly. Sometimes the fixes Google turns up for your model don't work because you have a different revision number. Most people, if they attempted to install Linux onto a recent, low-end laptop, would find a lot of things not working, like sound, or keyboard special keys. It's not rocket science to fix, but for them it might as well be.

This is not what 99% of the world signs on for when they buy a laptop, so it makes sense for someone to have a business that does this for people. But if you're in the business of doing that, you have to pay yourself for your labor. That means you can compete at rock bottom prices because that's where you're starting from in your costs; and in any case starting with a better quality device minimizes the work you have to do dealing with stuff like broken ACPI firmware.

Which means when you count the cost of your value added, it's really hard to sell a rebranded laptop at a competitive price. Selling high quality rebranded hardware at relatively high prices and small profits may be a way to bootstrap your business, but the only way to get serious volume sales at a profit is going to be to have a computer manufactured to your specifications.

Comment This might offset *warming* but not *change*. (Score 1) 247

Most of the greenhouse effect warming takes place in the summer, for the simple reason that's when the most solar radiation is received and trapped. This doesn't eliminate that effect, it offsets the increase in the *average* by adding an unnaturally cold winters -- which by the way would increase fossil fuel use dramatically.

Now this would -- if it is physically and economically feasible -- blunt *some* impacts of global warming, such as glacier retreat and sea level rise. But it would accelerate *other* effects, such as habitat loss and changes in rainfall. Other carbon driven changes like the emergence of carbon-loving weed populations would continue unabated.

Consequently assuming that it's practical, its effects would be at best mixed, and there would be some big-time winners and losers. People with a lot of money in waterfront property would be big winners; interior farmers who rely on historical rainfall and summer temperature patterns would lose. Trout fisherman would lose as warm-water species outcompete salmonid species in their historical range. Etc.

These kind of problems are inherent in any attempt to treat the *symptoms* of rapid, anthropogenic climate change. I you aren't going to use conservation and efficiency to attack the problem, then the most promising geoengineering solution is carbon sequestration -- if it can be achieved on the scale needed. In the ideal case you would set the CO2 levels back, say, to 1960s levels. Not necessarily pre-industrial, because people have already adapted to changes from pre-industrial levels, but low enough that the rate of climate change is closer to natural than what we have today.

Yes, but few strength training exercises require sticking your ass up in the air and waving it back and forth like that.

Straight leg dead lift. bent rows, and back hyperextension off the top of my head. And while we're on the subject of distracting and embarrassing, there's always leg abduction.

Anyhow, people are jerks toward anyone who gets serious about anything, whether it's biking, power lifting, or building electronics. You're supposed to be normal, not exceptional. That makes it easy to be a sanctimonious prig toward people who like things you don't have what it takes to try.

Ever go to a gym where there's rules about making too much noise because you'll scare the casuals? It's stupid. There's a woman in my gym, an ex-marine, who can dead lift over 2 1/2 her body weight, which for a woman puts her in the elite range. When I walk into the gym and she's doing it, I have to walk out because she sounds like a harpy ripping the head off a dragon. But it's my problem, not hers. That's what it takes for her to do her thing, and I'm not going to make her feel bad about it because it's awesome. Literally.

Celebrate people who dare to look, sound, or even be ridiculous. Even if it bothers you, that's not the same thing as harming you. The people who do harm are the self-appointed conformity police. The ones who automatically go after anyone who doesn't appear normal. "Normal" is must another word for "mediocre".

Comment Re:Plastic is lower density than water (Score 1) 48

Yeah. And I bet those stupid physical oceanographers don't realize that temperature and salinity gradients in the ocean are continuous either.

I mean it stands to reason. If you had a bathtub half full of cold fresh water and half full of warm salty water, pretty soon you'd end up with a tub full of warm brackish water, right? So the oceans must be the same. Contrariwise, the water in a bathtub has to drain clockwise in the northern hemisphere.
