Another One Down
So tired.
Want sleep.
Left hand and arm cramping.
(of course only I understand what the hell I'm typing about)

Cypress AT2LP RC42 problem?
I had a Venus DS3 enclosure giving me problems. The drive itself was fine. Oddly the other identical enclosure wasn't affected
1. Turn on enclosure (note: hard drive doesn't have to be in it)
2. Install the downloaded CyUSB driver. (note: I had to force Windows to install it manually)
3. Run primer.exe
4. Turn off enclosure
5. Turn on enclosure which programmed the ROM
6. Put back the hard drive, works as if I wasn't running during a thunderstorm.
didn't have to restart the computer
works for me, may not for you
---
so I didn't need to spend $40 for a new enclosure.
me needs a UPS.

Why does "prove" have one O?
Then again, move has one O and it has an Oo sound. Then why those 2 words with one O that makes an Oo sound?
ah.

Old Vauge Reference ... started July 2003
So then I wonder if there is something else. So, when I was really settled in, I left. No warning given. An so it was for two weeks of not ever seeing that place. Thoughts lingered in returning, there ware no intentin of permanently leaving; just the thought of when to come back, or what to say was the concern. I then returned though only a one day stay. Disapointing was that there wasn't that much of a change as I would expect. Now I await to see what is there to expect a week later.

Just Typing 041022
so now let us define that the powers of the Earth are the worst thing to ever do to this world. It is not that what I am thinking of bears any relavence to what it out there in the whole world wide universe, but there is something out there that is meant to be seen in this whole for the entire human race. Now such that anything would do, especially that anything there is to is possible. And so I end this brief essay for doing just that where everything is reserved and now there are losers and there are winner. I just happen to be a winner. The end.

MATH307 Ordinary Differential Equations | 060828
If there is only one independent variable then we have an ordinary differential equation (ODE). Otherwise a partial differential equation (PDE).
Order of a DE | the order of the highest derivative it contains
A DE is said to be linear if the dependent variable and its derivatives occur only linearly (to the first power), otherwise it is non-linear.
(y^i)^2+2sin(xy)=0 1st order ODE nonlinear
3y^iii+2y^i+y=e^x 3rd order ODE linear
3y^iii+2y^i+y=e^y 3rd order ODE nonlinear
d2u/dx2+2d2u/dxdy+du/dx=x^2+y^2 2nd order PDE linear
The most general nth order ODE takes the form
G[x,y,y^i, y^ii, … , y^(n)] = 0 (1)
or in principle we can write as
g^(n)=F(x,y,y^i,…,y^(n)) (2)
Any function y=f(x) that satisfies (1) [or (2)] identically in some interval I is called an explicit function of (1) [or (2)] in I.
An equation g(x,y)=0 that can be solved to give one or more explicit solutions is called an implicit solution.
Show that y=e^2x + 2e^x is an explicit solution of y^ii-3y^i+2y=0
y=e^2x + 2e^x, y^i = 2e^2x+2e^x, y^ii = 4e^2x+2e^x
y^ii-3y^i+2y=4e^2x+2e^x-3
= 0e^2x+0e^x=0 OK
