I always backup all my data and format the SW partition. Aesy, but some work to get all the settings right. Then again, I only have to do that once every 4 years or so.
I usually run the distribution I installed for years and years until I can't run new programs on it anymore, because of library issues and such. Then it's time to upgrade.
Ahh, the Apple puck mouse. What a pity it didn't make the top 25. I used one for a day. Instant RSI that thing will give you. Kudos to the person who designed that; you have to be really good to design a mouse that is SO bad.
Let's do the math. The hydrogen sits in the space between the atoms in a Pd crystal. We have to find out how many atoms fit in one unit cell, and what the volume of the unit cell is. Pd has a ccp crystal structure (see here for details). That is convenient, because that means there is one interstitial space per unit cell. The volume of the unit cell is 389.07^3 pm^3 or 5.89 * 10^-29 m^3. When hydrogen is absorbed by Pd, it splits in its atoms: H2 -> 2H. One interstitial space can contain one hydrogen atom. This means one molecule of hydrogen takes up 1.2*10^-28 m^3 in Pd. At room temperature and pressure an ideal gas takes up 22.4 l/mol. One mol contains 6.022 * 10^23 molecules. This means in the gas, one molecule of hydrogen takes op (22.4*10^-3)/(6.022*10^23) = 3.7* 10^-26 m^3. This is a factor of 315 more than it takes up in the Pd crystal. Indeed the value of 900 is either grossly overstated, or I have made an error in my calculation.
You are right. Adsorption occurs when some chemical or physical bond is formed between the adsorbant and the substrate. Absorption is, well, what you said. The Pd absorbs the hydrogen like a sponge.
I forgot to add that the hydrogen molecules in the Pd structure are much closer together that the hydrogen molecules in the gas. That's why Pd can absorb 900 times its own volume of hydrogen.
Hydrogen is a gas at room temperature. In a gas the molecules are very far apart. Therefore one mole (6.02*10^23 molecules) of hydrogen takes up 22.4 l, whilst one mole of Pd atoms take up only a few cubic cm. The hydrogen is so small it can easily penetrate the Pd crystal. It likes to sit between the Pd atoms, and can be easily transported in this way.
This sure is a nice program and I'm tempted to buy it, but only because it can help the police track down the criminal who stole my computer. But I would not want my computer back. Who knows where it's been, and how roughly it has been treated? I can't imagine that thieves treat computers with the care they need. My iBook was stolen recently, and although that is a PITA, I have backups so no data was lost. And with the money I got from the insurance company I can buy a new MacBook now!
I dont know about cancer, but a girl friend of mine lives in a house on the second floor opposite a school. There were always a lot of seagulls on the roof of this school, until they put a big GSM send/receive antenna there. Since this antenna is there, the seagulls stay away, so the radiation definately does something.
A friend of mine came up with this 'wonderful' (NOT!!) experiment you can do if you suddenly have twins. One of them you pamper and give it everything it wants, and the other one you neglect, shout at, well, basically, you treat him/her like Harry Potter was treated by his aunt and uncle. It would be interesting to see the results.
KIDS (AND PARENTS), DO NOT try this at home! Not with real kids, anyway! I will not take any responsibility for the results!
Like an old castle, Microsoft is slowly being abandoned and crumbling away. Like the old castle, they will probably be around for another thousand years or so.
Also, I have OS X running just fine on a 300MHz G3 from 1999. It's a little slower than I'd like, but it's by no means dog slow.
I have OS 10.3.9 on a 233 MHz iMac G3 with 256 MB. It's dog slow. But it will happily run Firefox, Thunderbird and iTunes for me, and iTunes almost never hiccups. Amazing.

I use about ten percent of the things listed. Does that make me a nerd?
Then they have no connection and they can't have a mobile telephnone call.
Most mobile phone calls are between people that are less than 10 km apart.
WTF??? I've always dreamt about Adobe Photoshop on my phone. Which model are you talking about? I want it! :-)
Instead of *gasp* MS hardware you can buy Logitech. They make nice mice too.

So they present an 'open' standard in a document formatted in the closed .doc format. Way to go MS! Your true colors shine beautifully.
So that's why MS provided the specs in .doc format!
That isn't even funny anymore. I knew MS `innovated' some parts of OS X, but I had no idea it was this bad!
Great videos, thanks for the links!

But if Grandma decides she wants to become an expert sysadmin on the Mac she still can use these three books!

Good point. I don't think you can run Linux in a bucket of water.
That would be 3000 then.
