Experts Say Hitching a Ride In an Airliner's Wheel Well Is Not a Good Idea

And no waiting in the queue for the toilet either.

Waiting in the queue for the toilet is prohibited. It's what terrorists do before they strike.

Experts Say Hitching a Ride In an Airliner's Wheel Well Is Not a Good Idea

Ihlosi Re:Wheel-well traveling 101: (216 comments)

Oxygen getting absorbed in your lungs depends on that pressure, less pressure, less oxygen gets to your blood.

This is why you want to increases the ratio of oxygen in the gas mixture you breathe when ambient pressure drops. If ambient pressure is only 25% of what it is at sea level, you'll need to adjust the gas mixture to 80% O2, 20%N2 to have roughly the same partial pressure of oxygen.

The acclimatization is more a matter of coping with the lower CO2 level (CO2 partial pressure also drops, causing the body to exhale more CO2, which causes hypocapnia and affects the acid-base-balance of the body and various other functions.).

... you might as well make the reason alcohol intoxication instead of hypoxia.
Also, bring hard liquor. The hardest stuff you can find. Anything else might freeze.

1. Dress warmly. Even if the plane takes off in a tropical location. Make sure to cover exposed body parts - you don't want to pay with eary, fingers, toes or your nose for the trip.
2. Bring oxygen (that's going to be the hard part. Several hours worth of oxygen).
3. Familiarize yourself with various plane types so you don't get crushed by an unsuitable wheel well design.
4. Secure yourself to the plane so you don't get thrown out during landing.

No annoying seat neighbors. No screaming kids within earshot. Not getting groped and molested while going through security. You can bring any amount of liquids. You can even bring and consume your own alcohol. Etc ..

Student Records Kids Who Bully Him, Then Gets Threatened With Wiretapping Charge

Ihlosi Re:So while all of this was happening (796 comments)

4. Figure out why you're a target and change it.

... because you have a physical, mental or behavioral disability.
... because you have better grades than the bullies.
... because you don't like what everyone else likes.
... because your parents are richer or poorer than the bullies'

Have fun changinge any of those, even with all the intelligence in the world (well, you might change #2 by playing dumb). Your blaming the victim borders on the absurd.

Student Records Kids Who Bully Him, Then Gets Threatened With Wiretapping Charge

Ihlosi Re:Same old, same old. (796 comments)

To this day I'll never understand why teachers were so blind to the fact that the bigger stronger "athletic" kids constantly harassed the weaker kids.

You're lucky, since in your case the bullies were actually considered to be part of the party at fault.

And the teachers actions are easy to understand when you realize that they're not interested in justice - they want peace in the classroom.

2. The abused should learn how to defend himself. Send him to a karate class.

Bullies either have advantage in numbers, or they're very, very good at playing victim once they encounter any kind of "defense".

Basically, the victim has three options:

1. Suck it up. Leads to all kinds of physical and mental scars.

2. Report it to the proper authorities. Victim gets punished. Bullying does not stop.

3. Defend themselves. Victim gets punished by authorities. Bullies resume bullying.

Jenny McCarthy: "I Am Not Anti-Vaccine'"

Ihlosi Re:You can get autism from measles. (588 comments)

My personal bet is on a chemical that began being used heavily in industry in the 70/80's.

My personal bet is that the reproduction rate in industrialized countries dropped, but it did not drop uniformly. It dropped more sharply for people with fewer genetic risk factors for autism (which means they're less likely to be affected themselves) and less sharply for people with those risk factors.

The "increasing rate of autism" is actually an illusion caused by mostly two things:

1) Much finer detection methods (people diagnosed with autism today wouldn't have gotten the same diagnosis 30 years ago - "Autism? Huh, he can talk just fine.")

2) The nonuniform fertility rate drop mentioned above. Neurotypical people are just too busy to have kids, or don't want to burden themselves with kids, or whatever. Even a slight shift in the ratio will send the ratio of autistic kids to neurotypical kids through the roof, completely without any mystery chemical or completely new causes of autism.

I regularly scan pubmed for publications on the topic, and the case for genetic risk factor being a major, if not the major cause of autism is just overwhelmingly solid.

Jenny McCarthy: "I Am Not Anti-Vaccine'"

Ihlosi You can get autism from measles. (588 comments)

Meningitis and encephalitis are known complications of measles, and either can lead to permanent brain damage. Depending on the location and severity of this damage, the symptoms can be indistinguishable from "true" autism (which is mostly genetic).

Heartbleed Coder: Bug In OpenSSL Was an Honest Mistake

Ihlosi Re:Whatever you may think ... (446 comments)

Every time I make a mistake I remind the client that if I were perfect they'd have to be paying me a lot more money.

In fact, the amount of money is inversely proportional to the probability of bugs. A perfect developer costs an infinite amount of money.

Navy Creates Fuel From Seawater

Ihlosi Re:"Unwanted" Methane? (256 comments)

Specifically the methane has to be cooled to -161.49C at 1atm,

In that case, you'd end up with a gaseous fraction that's mostly hydrogen, and a liquid fraction that's methane plus everything else.

I would assume you'd have to cool the mixture to a temperature between -161.49ÂC and -42ÂC (boiling point of the next heavier alkane, propane), so you get hydrogen and methane in the gaseous fraction, and propane and heavier alkanes in the liquid fraction.

Navy Creates Fuel From Seawater

Ihlosi Depends on the effort. (256 comments)

It depends upon what sort of fuel you're trying to produce.

And on how difficult (read: expensive) it is to avoid unwanted byproducts. And on the possible market value of the byproducts.

If you can sell the liquid hydrocarbons that you want to produce and the methane that appears as a by-product for almost the same price, it would be economically counterproductive to spend money on reducing the fraction of unwanted methane. Just produce both and sell both.

Ihlosi "Unwanted" Methane? (256 comments)

In a civilian application, it wouldn't be necessary to spend effort in the process to reduce methane production. Just feed the methane into the natural gas network.

NASA Laying Foundation For Jupiter Moon Space Mission

Ihlosi Re:Permanent Habitat? (100 comments)

If something goes wrong on Mars, you're dead. There's no rescue.

Sudden evacuation might be problematic. But with less serious problems, the lower transit time to Mars vs. Europa might be advantageous. You're dead anyway within about 24 months from the lower gravity and radiation (or suicide, if sickness doesn't get you first).

There's no experience with humans living in low gravity conditions for more than a few days. We have plenty of zero-g experience, but none that would tell us what a few months of 1/3 g would do to the human body.

Radiation is a problem, though. Shielded habitats would be a high priority. Either underground, or possibly by using water (produced on-site) as shielding.

How Many People Does It Take To Colonize Another Star System?

Ihlosi Figure out how to ... (392 comments)

... create genetic variety in an artificial way. Hey, if you can get _two_ people (and tons of robots) to another star system, then doing a little bit of DNA-related organic chemistry shouldn't be too hard.

In effect, for a few generations, you could introduce intentional mutations that are known to be somewhere between "marginally harmful" and "beneficial", until the gene pool is large enough that things can be left to random chance again, if the colonists desire.

Should NASA Send Astronauts On Voluntary One-Way Missions?

Ihlosi At some point, colonization will be ... (307 comments)

... de facto one-way. If there's a chance of living to a ripe old age where you're going, then voluntary one-way missions are perfectly fine, especially when they come with the opportunity to stake a claim.

If "one-way" implies using your favorite method of suicide after a few months, then no.
