I had a revelation before my last eye exam. I've been wearing glasses for 10+ years and I noticed indents where they sit on the side of my head. When I went for my check up I had to ask my doctor if this was an indent in the skull or just the tissue? More important was the question, would they go away with the absence of glasses (contacts)?

As it turns out, it depends. As I learned, if you were wearing glasses when you were younger (ages 0-10), there there might be some slight indents, but it's like foot-binding - unless there's a forceful binding for an extended period of time, you're not likely to see any deformation of your bone structure.

It works the same way that growing trees do. If you put something in the way of the natural growth that the organism can't overpower, it will grow around it.

Bones are strong, and humans move around a lot.

That being said, if you were wearing glasses for the past ten years, you've likely developed small callouses from where the arms of your glasses might have been rubbing behind your ears. I've been wearing glasses for over ten years, as well, and I have them. The more often you wear your glasses, the harder they will feel, and the deeper your callouses will run.

I am not sure if I was pleased with the information or not.

When I was growing up I got an allowance that consisted of a dollar and twenty five cents, each week. I had to work hard for the money, but it meant that I could buy candy and things like that.

One thing that it didn't teach me was how to manage my money.

As our daughter gets older we wanted to work something else out than allowance. Something that would help her get used to managing her money. Now what we do is put a small amount of money in to an account for her each week.

She has to check the balance, plan, and then use her card.

We have over draft protection and she is only allowed to withdrawn 80% of what is in the account.

So far I am pleased with the results. At first she was scared of the idea, but now she has taken to it with finesse.

If you want to teach your child about responsible spending this might work for you.

My co-workers son explained the web, at least the Web 2.0 as he understood it while playing with his phone. He is nine.

It came down to the Wed 2.0 is better than the Web 1.0. It took ten minutes.

Let's look at it again though, and I will leave his ideas out. The Web 2.0 referred to the shift between the web being sites published by 'experts', ie people who had the ability to publish websites, and read by passive readers, to the web being a social forum where the readers can also make the content in the form of blogs, twitter, forums, etc.

It is, then, a figure of speech used to basically shorthand for "people interacting together on the web."

It is less common today than it was when it first got coined, first because it wasn't a very useful or meaningful expression to begin with, and second because by definition, all those things-nobody-had-thought-of-before ten years ago are now old hat.

It seems like every time that I upgrade my phone it is due to the RAM I had. The RAM had gone out. And I out grew my RAM. But what is it?

The computer's RAM is like counter-top space.

Everything in RAM is easy for the processor to get at, so if you have a lot of counter space, the chef can work on preparing more things at once. If you don't have enough counter space, the chef can't work on as many things. Some programs use a lot of RAM, just like some recipes call for a lot of ingredients, so it is harder to fit more stuff on the counter.

The data when you download an app is put in storage (like a hard drive). Think of this like a book. All the information is written down somewhere. Even though you don't know it all yourself, you know where to find the info.

RAM is like your own short term memory. You can remember quite a bit but you will forget it pretty quickly when you start thinking about something else.

When you do something with the app its like reading the book and then remembering what you are supposed to do. Let's say you open up a menu. You need to remember what page in the app you are on. You do not write this information back into the book, you just remember it.

Now let's say you open another app and navigate to a menu in there. You have to remember what page you are on in 2 apps at the same time. The more RAM you have (the more you can remember at once before you forget) the more you do at the same time.

If you have a smartphone now you can explore this. Open your browser and go to a site. Now close the app and open it again. Hopefully, the app did not refresh the page. This is because all the page data is still stored in RAM. Open a different app like twitter. Now go back to the browser. Did it refresh this time? If not, it's because you have the page data and twitter feed in RAM still. Eventually, if you keep opening apps you will run out of RAM and your phone will move the browser data to long term storage. This is like making notes in your book. When you open the browser again it will read what web page you were on when you closed it and open it again. All the data downloaded won't be there any more and so you will see the page refreshing.

The more RAM you have, the more things you can have open before this starts happening.

If you don't have a lot of RAM, it is like not having a very good short term memory. You need to keep checking the book to see what it says because you can't remember very much. This means that if you try to do something complicated it will take much longer. It also means that you can't do many things at once.

When you're playing a game, it would copy all the stuff it needs for that level from the storage space into RAM so it can bring it all up as needed. That's also why you sometimes have loading screens in games when you go from one area into another. It puts a whole new set of things into the RAM.

I recently watched a snippet on CNN business about a company changing hands. While I wasn't sure what exactly would happen with a company, the simplest logic is the best logic.

For example when a company sells the money goes to the shareholders. In the most simple example, you are a sole proprietor and sell a business, are thus the only shareholder and get all the money.

At the other end of the spectrum are public companies with thousands or millions of shareholders who get bought out -- for example when Exxon bought Mobil. The shareholders who owned Mobil shares got cash at the deal valuation in return for their shares, say $50/share x however many they owned. Or a merger might be paid out in shares of the new company. So if you owned shares in ABC when Disney bought them, you might get 2 shares of Disney for every 5 shares in ABC you owned.

In the case of something like PayPal being sold as a private company, there would be a number of large shareholders like Elon Musk and other co-founders, as well as the venture capital firms that funded them. When you hear that Company X received a $20 million investment at a $1 billion valuation, then that would mean that venture capitalists bought 5% of the company for $20 million. And there could be a couple or a few dozen such investors depending on the stakes purchased, rounds of financing, etc. Then there are the small shareholders, like employees who got shares as part of their compensation package.

So PayPal gets sold, and the 3 founders each owned 10% of the company by that point after selling off chunks to investors, or $180 million each from the $1.8 billion. The venture capital investors own 60% and split about $1.1 billion based on their fraction of ownership.

And the 1000's of employee with tiny portions get the other $180 million.
