05/20/10 stop me if you’ve heard this more binary

november
11/23/10 trying again dammit P_2(Z_5)
11/23/10 perhaps *this* will refresh your memory P_2(Z_2)*
11/23/10 now here’s something you’ll *really* like more P_2(Z_2)

  1. There are 4 quarts to a gallon, 2 pints to a quart, and 16 ounces to a pint.  There are 4 ounces to a gill.  There are (about) 26.4 gallons in a hectoliter.  How many gills are in a hectoliter?  Display the unit fractions for your calculation.
  2.   Write as a single number in scientific notation:  ( 1.5 * 10^{-17} ) / ( 7.5 * 10^8 ). 

3.  Consider sets X, Y, and Z in a universal set U, where

U = {b, i, g, f, a, t, c, o, d, e}

X = {e, g, b, d, f}

Y = {f, a, c, e}

Z = {b, e, a, t}.

Use the operations \prime, \cap, \cup—complement, intersection, and union—to find the sets represented by the given expressions.

X \cap Y = { f, e}

Y \cup Z =

Z’ =

(Y \cup Z)’ =

(X \cap Y) \cup Z’ =

X \cap (Y \cup Z)’ = 

  4. Sum the sequence: 88 + 99 +110 +  . . . + 462.

  5.  Expand the expression (x-3)^4.

  6.  250 beverages are tested for Purity, Body, and Flavor.

65 pass the Purity test.

95 pass the Body test.

90 pass the Flavor test.

20 pass on both Purity and Body.

25 pass on both Purity and Flavor.

40 pass on both Body and Flavor.

5 pass all three of the tests.

How many of the beverages pass *none* of the tests?

wp fail

@#$%!

i mean it this time.

cut & paste

this is only a test. had i really known how to this,

that would’ve been an ordinary carriage-return-

-line feed the way boole intended. but *no*! instead we get this crazy horse-shit where the editor puts in the c-r-l’s like it knows better than one’s own living self where the damn things are supposed to go. so the whole thing’s off. it is impossible to work under these conditions.

below the asterisks, cut-&-pasted stuff. somehow this still works. not for long i bet. anyway none of my concern now. at long last i can drag-and-drop JPGs (or what have you) from web to mac-book to web & have it work pretty much (instead of driving me around the bend trying to figure out what they want me to do with that g-d d-mn mouse). no good to me now that i can’t enter copy in any of the interfaces without wrestling robots. just another lost blog-slash-soundcloud-slash-photothingum. fuck this forever.

stuff by me. go read some.

trying one more time.

uh-oh. carriage-return has been given a weird function.

*now* what? i clicked a +-sign button &c. supposedly

something about a block. nothing happened. trying again.

dürer

okay. putting in a graphics block works like that.

this is allegedly "preformatted".  which, 
okay, at least doesn't punish you with the
carriage-return-line-feed misfeature, but,
still, won't even let me write "preformatted"
without touching the mouse to tell the damn
thing i actually mean what i actually type.
over and over.  and this is a word i *copied*
from *this ghastly format itself*, which 
would make it even funnier if it were funny
at all instead of inspiring of rage & despair.

another block now. okay. maybe i’ll be back.

Photo on 9-11-20 at 8.49 AM

so here’s the thing i’ve been in the process

of memorizing ever since i worked it out.

i *almost* know it now.  this interface sucks.

bye now.

an awesome work of scholarship.
by a great musician and lay leader.
but not my real subject.

(bait-and switch.) 
UUUE.me .  
(the editor hates plain-text and wants me 
to learn about "block"s.  not today.  
dates & titles; formatting not my fault.)
