Comment Re:Amateur chemistry is all but impossible now (Score 4, Interesting) 189

You know i had this problem when i wanted 50% H2O2. The lab supplier said no, regardless of what paper work i came up with. But the industrial suppler was like "We don't sell one liter bottles, but 25kg is $50", which was about the same price as 1 liter from the lab suppler. I asked about permits etc. All i needed was a dangerous good vehicle if i was transporting more than 100kg. They also sold me some red fuming HNO3.

Turns out at least in some countries there is a lot of "assumed" laws that don't exist. And lab suppliers seem to be paranoid.

Comment Re:I thought the methane ocean was of interest? (Score 1) 59

This is in fact quite difficult. Sure in some sci fi story it works because you just arm wave all the details away. But when it really comes down to what can really work its more limited. First off methane is a poor universal solvent compared to water. This already makes things much more difficult. Second even the basic idea of a bi-lipid membrane doesn't even work in methane (its a non polar solvent). Its cold so reaction rates are low... etc....

Different building blocks is even more difficult. The classic argument is something based of silicon. If you have silicon you have carbon and carbon can just form so many more stable compounds that anything else, and vastly more than silicon. Life as we know it uses most of the periodic table. The is a really good argument to be made that life will be chemically similar to us. (ie water is the solvent, things based around carbon, some sort of information store like DNA).

My daughter is now 22 and living in a different country. But we had the same polices. Food, power, rent and video games are not free and i am not your cash cow. Also there is basic household cores that need to be done. Pull your weight or get your own place. In the end we made her get her own place. Mostly for being exceptionally rude to us. It help our relationship dramatically (shock horror power bills and *internet* bills made her panic). She still flunked school. But she is a stable happy person that is now working out whats next in life while she saves from a steady job.

When i install linux i do a full install. That is about 10min now with a SDD drive. That includes full latex, open office, about 5 desktop environments, open office a bunch of browsers and almost everything i need out of the box. I have never needed to reboot after install or "update", hell i have laptops with uptimes at almost a year.
