I really like puzzles and this was a very good challenge. Figuring out the fault wasn't all that geeky. Figuring out a work around was kind of geeky. Taking great pleasure in using the work around for a long time was totally geeky.

The dishwasher is currently hard wired to the electrical power. That may be how the controller got fried as here in FLA we have a lot of lightning. Once the new controller arrives I will convert everything to a grounded three prong connections and add a surge protector.

My kids got completely hooked from Hour of Code. It's awesome. Two working in Scratch, and one working in Python.

Funny there's no mention of MapMyRide/Run/Fitness in there. It's an Austin company that I might like to work with some day, but their Android app sucked the last time I tried it. Interestingly, Under Armour is acquiring them.

Very cool that it's stable and unexpected. Neat.

Daughter is working on a skiing game based on my simulated 3-D concept. We got the obstacles approaching you from the distance and getting bigger as they go. Should be ready to roll in the next day or two.

You're welcome.

My daughter shared her "skiing game" tonight: https://scratch.mit.edu/projects/16766335/

It's not done, but she wanted to get it out. Actually sort of fun to play.

Got my first favorite project star. Probably one of WR's 9 year old students... who will then tidy things up.

They still need so much help with the math. It clicks after I show them, but I'm having a tough time hinting them towards solutions on their own. That's fine though, my daughter is the most interested of the three, and she grinds and grinds until she's really stuck, then asks for help.

Amazing that it's done with so little code. I have no idea how it works.

Man, I can't figure out how that one line would compile. No time to dig into it now though. Quick reformat:

(looks like BF re-jiggers a closing curly brace into "**")
Code:
k;double sin(),cos();


main()
{
    float A=0,B=0,i,j,z[1760];
    char b[1760];
    printf("\x1b[2J");
    for(;;)
    {
        memset(b,32,1760);
        memset(z,0,7040);
        ;
        for(j=0;6.28>j;j+=0.07)
            for(i=0;6.28>i;i+=0.02)
            {
                float   c=sin(i),
                        d=cos(j),
                        e=sin(A),
                        f=sin(j),
                        g=cos(A),

I felt like by the time I was reading about it on CNN and in Reuters articles, it was too late to get in on it.

"Mining" it doesn't sound like it's worth it in terms of the power consumption costs.. so that leaves buying it I guess.

And at that point you're just speculating on a wildly fluctuating asset, from what I can tell. I don't like that much risk so I'm sticking with the 401k.

All of that said, I'm pretty sure the total # of bitcoins is limited - when the last one is mined, I would think demand for it would go up and so would the price.. but I have no idea really.

Bitcoin is interesting. When I first heard about it I could have started mining and maybe gotten a few, but they were only worth a dollar or so, so I didn't really care. Now the mining is only effective if you have a huge network of specialized machines, and even then the power costs almost outrun the gain. And yeah, buying right now is a risky buy. The whole thing could collapse in on itself leaving you with nothing. Or it could continue to appreciate at staggering rates. The total number of bitcoins is indeed finite, at 21 million. However, this is just code, and could be changed in the future (unlikely?).

The limit will be reached in 2140 ('cuz math and stuff). If you bought in early, you could've made a fortune. But you could've also lost it all, based on all the other coins you would have bought that have since disappeared. Will the price of a bitcoin go to $100k like some smart people think? I dunno. It's certainly possible if it becomes the defacto standard for the world. That seems unlikely to me for a number of reasons, not the least of which is the fact that you'd have to pay .0000001 bitcoins for a coffee, etc, and the government will never let the printing of physical coins overtake actually US Dollars because it's too valuable and too important.

Should you buy one? I've thought about it, maybe it'll be worth 100 or 1000 times what it is now sometime, but I think it's more likely it will die off, so I'm leaving my money in the stock market (which at least won't go to 0 when it inevitably crashes again).

There's also litecoin, dogecoin, and even koinye.. probably hundreds more virtual currencies. Some of them are literally a joke.

From what I hear some of those are still feasible to mine cost-effectively (using special graphics cards), and you can convert them into bitcoins. So maybe those would be better to get in to now, since they aren't mainstream yet.

But yeah it's all too volatile for me..
