One thing I learned when feeling blue is this:
Even living in a sunny place like AZ, we don't get enough vitamin D.
You'll have to look it up, I need to get some sleep, but vitamin D plays an important part in the brain, without enough, forms of depression are not far away.

I got a "Philips Energylight" (HF-3308) several years ago it's ugly as it can get,
it even has a yellow tinted base (YUCK!) but I love that thing...

So thanks Joe, but I got that covered..
And to those who wonder:
It indeed helps.

:thumbsup: Glad to see you back. At least it wasn't a math meltdown this time, so we can't say you are insane.

My father has been ill for a couple of months, and 2 weeks ago he passed away. With all this happening, i just have not had the motivation to read go kart related stuff and answer all these repetitive questions from noobs that we have been talking about here.

Paul, Sorry to hear that news. Hang in there man.
We will be here, For whatever that is worth. :cool:

No thanks :worried2:

So as Tony said, us mods are not having a good time of it. Not to detract from Alex's thread, but maybe i should let you guys know why i haven't been around much either. Or at least not posting that much.

I also want to see this forum stay like it was when i first joined 6 years ago. I have also noticed that it had been slowly sliding downhill.

So please bear with me at the moment. I will still be around checking up on you guys, but maybe just not posting as much
Sorry for your loss.

LOOOL yeah at least it's not that.. that was indeed weird.. even for me.
I still have the feeling it could be tackled (it can't .. smarter minds than mine have failed at least...) but I have no intention to really try again.

Nothing a good PB&J sandwich couldn't cure!
Only if wifey or girlfriend made it, then it's a cure. Otherwise it's just more work.

Hope you guys take that as the joke it really is...otherwise the lack of humor is quite....disturbing.

It can't?

I say, just hasn't been done yet! :thumbsup:

"They" said

...man couldn't fly - until the Wright bros.

...auto driving carriages - yea, right!

Always "try" to keep an open mind about stuff. :2guns:

Just think, perpetual motion (of some kind) is right around the corner. IMO

Look at the difference between the old incandescent bulb & a LED.

Huge (unthinkable) difference in the amount of actual light out put, power consumption & even the color/quality of light.

you misunderstood.
it can't means indeed it can't "today" since it's a matter of computing power.
quantum computers could (in theory) tackle that quite easily.

What I was trying is to find is an algorithm that can today with todays computing powers.
one that's not even trying to do any guesswork, but is actually calculating results.

And that has been tried by many __professional__ mathematicians in well over 300 years so far.
I think it's safe to assume that a hobbyist like me is not exactly likely to find a solution to that within a few weeks or even months.

Somewhere I missed the Big question. It's probably over my head anyways.:p

Factorisation of huuuuge numbers
(google RSA cracking to get an idea)

in short: you have a massively large number (1024 bits or 2048 bits or 4096....)
that's the product of two unknown prime numbers (about half it's size.. 512, 1024, 2048 bits...)
The task is to find those two primes ...

each is about'ish 2*10^153 at least (two followed by 153 zeros) in size
compared to the estimated number of atoms in the observable universe (1* 10^80; a one followed by 80 zeros)
you could imagine just HOW large those numbers are.
and that simple trial and error would not get you very far.
And even testing with current methods on networks of thousands of modern computers takes several dozen years.
(A reason why an RSA cerificate is renewed every few years with doubling it's size every now and then, to have those networks have to start over again and grow to keep up as well)

Without going into too much detail (more to keep me sane than to keep you uninformed ;))
I thought that calculating the remainders over a "large enough" span of Moduli could reveal an interference pattern, that when analysed would show the exact difference between the two primes.
(knowing the difference is all you need to calculate both primes)

it's... well.... insane, simply put;
at least for numbers that size.

Move to OT if this discussion is going to keep going.

Season disorder is a real deal! My wife and I are planning a trip to Mexico at the moment. Oddly didn't get enough beach / water time during the summer so we're trying to make up ground.
