Hello Michael,

Quote:

Goodness, didn't you get an estimate, or a second opinion, before your
dentist began work?


It's rework on something done in Europe and there aren't too many that
would even touch it.

Estimates with dentists are often elusive. When you are sitting there
and the pain is shooting up to the cranium there ain't much motivation
to shop ;-)


Quote:
About a year ago, we switched dentists (bad service); our new dentist
wanted to do about $500 worth of major crown work for my wife. Decided
to get a second opinion. Second opinion said the crows weren't
necessary; only a filling. We switched dentists again to that one
ASAP.


Well, we did shop around and for most work like root canals the others
were even higher. Plus our dentist is really good. It's just that
sometimes the bills make you cringe.

If we would just live closer to the Mexican border this burden would be
much less heavy.

Hello Tim,

Quote:

After finding some possibly useful routines to calculate filters (wave
digital in this case) I got stuck because these are for Matlab. I only
have Scilab and next to no experience with it. The files are mostly
*.m, some *.p and a few graphics GUI files *.fig. Scilab doesn't
understand any of these.

Is there a text somewhere, along the lines of "Matlab to Scilab file
conversion for dummies"?

The brief instructions for routines like "loadmatfile" on Scilab's
site are simply not verbose enough for an analog guys like me :-(

Octave is quite compatible with MatLab.

I like the SciLab syntax and environment better, but it's _not_ friendly
to beginners (but then neither are MatLab or Octave).

SciLab does have routines to translate a matlab script into a scilab
script. Typing 'help matlab' at the command line will get you quite a
few hits. The conversion covers the *.m files, but I'm not sure what
the *.p or *.fig files do, or if SciLab can handle them. There is a
SciLab newsgroup on which you can post your questions --
comp.soft-sys.scilab.org.


That's what I had tried, using the "loadmatfile" routine. I tried
several m-files and got errors and aborts on all of them.

In the old days things were easier. Universities would compile
everything into a nice DOS executable like the program by
Prof.Mildenberger's team. It has a wave digital filter section which is
what I am after. I had bought this program from them around 1990. Fair
price and most of the money went to good cause. Later it became
shareware but now he is retired and his site is down.

Nowadays they often post vast piles of files, either for some obscure
operating system system or for a math program that they happened to
have. I really don't understand why they don't walk the last mile and
create a nice stand alone package. They could make money from that and
most faculties are in dire need of funds. That would also serve as a
teaching tool to students and Ph.D. candidates so they learn project
management, proper documentation, and what it takes to create a saleable
product.


Quote:
Absent considerations of being compatible with industry, I recommend
SciLab over MatLab - even if both were free. If you're going to do a
lot of work with customers who want m files then you're kind of stuck
with MatLab or Octave, but I haven't had that happen to me more than
once in the last three years.


Well, mostly I am stuck with industry standards. For example, I must
create my docs in Word. In this case I'd just like to try out some
filter design software but I am finding that the efforts to create an
environment for these to run might outweigh the benefits. Might as well
go back to notepad, sliderule and HP calculator. Plus maybe some Excel
spreadsheeting.

Email me the files -- I'll give it a whirl and either let you know or

send you working ones.

Thanks. I'll do that tomorrow. Have to find out which ones are
important. The docs are, well, skimpy and it seems that dozens of are
are being called from the GUI at times. But at least they are all small,
a few kB.

Now it's off to the barbie, pork chops tonight. Then a neighbor called
saying she has a couple of rather active hornets nests. Oh man...

I like starting fluid. They make crazy spirals as they try to get
out of the cloud of ether. ;-)

I like Wasp and Hornet Killer. The guys who developed that stuff
should win a Nobel prize, IMHO.

I always seem to pick up an empty can of Wasp spray when I need it,
but there is almost always a can of starting fluid handy.

All this chemical stuff seems to create resistant mutations of the bugs.
Once I held this spray in the black cans onto a nest, one hornet buzzed
out, remained right in the stream for several seconds and then came
after me. I hid inside and that thing did not die. Amazing.

I am not sure we are doing us any good in the long term. Also, this
stuff generally is nerve gas and who knows what it'll do to us humans.

Where do you get the freeze spray? Or do you have to spray a random
pressurized bottle upside-down?

I'd like to see a fly develop a mutation against freezing...

Sure, but freeze mist and stuff like that for electronics work is
usually mail order. Also, you have to get close up. With hornets you
have exactly one shot and then they'll come after you. The hornet killer
cans can cover about 20ft distance with a pretty good aim. But I always
clean up the drippings before kids or pets enter the area again.

Some of the production techs at Microdyne were doing that. It
surprised the hell out of them when they thawed out and took off.

We have some that nest underground in FLorida. The starting fluid
(Ether) flows into every tunnel and kills all of them.
