linuxcnc.org is down. (joomla)
yea - arg with the extra sounded H at the end
yeah, works here too
I found out yesterday that dreamhost keeps 6 sets of backups automatically
two hourlies, two dailies, and two weeklies
works here also now
honestly - it was down.. :)
um - yeah. sure
for dreamhost downtime, that sure was short
usually they try to stay down for at least hours at a time, so that everyone gets a chance to gripe
someone in this house's history really needed to learn about plumbing
"let's install a bathroom in the basement"
break a hole in the main sewer line, lay the plastic drain lines from basement toilet and sink next to/on top of the main line
cover the whole thing in a massive lump of hydraulic cement
"done, let's go have a beer"
wyes? tees? we don't need no steenkin' fittings!
Umm - having problems?
* skunkwork is glad this old house had new plumbing under it..
jmkasunich: now that you have a nice new camera - we expect play by play pictures of the plumbing carnage. (we don't get out much)
fortunately I removed the bathroom and plugged the lines years ago - I want basment space more than another crapper
so all we need to do is cut out the plumbers nightmare and lay a new main line out to the part that is being repaired anyway
I will post pics - I already took a couple of the nightmare, but I'll get a better one after some of the dirt is removed
unfortunately, the outside digging probably won't start till tomorrow, the backhoe is busy elsewhere
I got my 34 yards of sand delivered for the garage this morning.
building a new one?
34 yards seems like a lot of sand
hah - doesn't look like much :)
This house was moved onto this lot - no garage.

hydraulic cement is some incredibly tough stuff
especially when its 8" thick
most of the floor isn't much over 2", but that block took quite a bit of jackhammering to open up
make sure to wipe off the machines when they're done
I thought about tarping things, but when he started there wasn't much dust at all
and then ...
_until_ he hit the big chunk, and by then it was too late
not shown in the pics is a vertical piece of 3" black ABS pipe - they had a floor drain going into that same hole
I am sure there wasn't a building permit issued for that work :)
I had a little handheld computer with IIRC a 4004?
or was it a 4040
I didn't think the 4004 was in much except calculators
saw this on a wall today: http://www.mightywombat.com/oldtoon.php?year=2007&id=297
"The Ventrix 4004 computer is Windows Vista ready."

"A real working computer using the Intel 4004/4040."
I chose wire-wrap as my construction method because it ... is also reliable and very durable
it is actually pretty durable - no problems from board flexure
SMT components can fracture (almost impossible to spot) if the board bends even briefly
could have swore it was a 4004 http://oldcomputers.net/Panasonic_HHC.html
huh, I used to have a stack of those
wow look at that nice printer output!
I think - either I threw it out - or it went on ebay.
(I had the printer also)
yep I had a printer or two, don't remember ever seeing one work though
I think mine worked ok - didn't do anything with it.
I got the lot from a junkpile somewhere - on the eproms was some insurance/actuarial software
they're probably gone now, lost during a move
I would have been really sad if they were 4004 and I lost them :-)
this is what got me thru collage. http://cgi.ebay.com/Vintage-Tandy-Pocket-PC-6-Computer-Works_W0QQitemZ230158355858QQihZ013QQcategoryZ1247QQcmdZViewItem
still have it - 8K of memory
expandable to 16 iirc
I just had an HP48
I had the previous version that had only 1k - I thought when I got the new 8k one - I would never fill it up ;)
[[1 2 3][4 5 6][7 8 9]]
[2 3 4]
I never got into rpn
I still can't use a normal calculator without bitching
when I hit a number key and my previous answer is gone forever...
I loved being able to write exactly the way it was formated (5*6)/108*(6/5) or whatever.
you can do that on hp48, just type the ' key first
maybe I could have gotten along with it ;)
but ... nothing is ever written that way
it is in my head
is the 6/5 on the top or bottom of the first / ?
my HP 28C and 28S helped me a lot in college
that's a terrible way to write a formula
just having the units reference was extremely handy on several exams
sorry, this is a religious argument
yeah it's utterly clear what the value of skunkwork's expression is
I actually scroed 100 on a physics exam largely because I was able to balance units correctly
scored, that is
yay! routing completion: 100% woohoo!
SWPadnos: how long did that take?
waaaaay too long
I did it manually
board layout? I first figured you were talking fpga place & route
ah - nope, not this time
later this week ;)
SWPadnos: good for you!
(real men route by hand)
thanks. all i have to do now is figure out how to get correct gerber files for the PCB house, and correct XY data for the assembly house, and manufacturer part numbers for the 274 components, and get everything on order
should be easy to get done by 7:00 or so
I get .33333 ;)
my answer is equal to 1/3 ...
>>> (5*6)/108*(6/5) == 1/3
>>> 0 == 1/3
> (/ (* 5 6) (* 108 (/ 6 5)))
what program is that?
it all depends on whether the (6/5) goes in the numerator or the denominator
fenn: lisp interpreter
order of operations - order of operations..
SWPadnos: yeah my point exactly, it's a bad way to write a formula
skunkwork: "order of operations - order of operations" is also equal to zero
> (/ (* 5 6 6 5) 108)
of operations of operations
I still don't know how skunkwork got 1/3
> (/ (* 5 6 (/ 6 5)) 108)
oh my mistake
so in the traditional order of operations * and / are the same precedence, right?
do you evaluate R2L or L2R?
parentheses first - then left to right.
jepler nice "1"
if you go L2R, I think you end up with the first thing I typed which is 25/108
it doesnt matter which direction you read it, the * or / operator applies to the thing to its right
left to right, you get 1/108
* cradek shrugs
((5/6) / 108) * (6/5)
the 5/6 and 6/5 cancel
oh, well that's different :)
(5*6)/108*(6/5) = 30/108*1.2 = .3333
sorry for causing a total waste of time..
sorry skunkworks that's wrong
I don't know how to evaluate 30/180*1.2
left to right.
(it is how 2 different calculators evaluated it also.) so it must be right ;)
oh crap.. swp messed up the equation
everyone please refer to page 103 of your textbooks for the correct problem
oh - 5*6 - that explains it ;)
* SWPadnos goes back to PCB inspection
