So that can't be Pi, it must be something else! That's not a use case for Pi that anyone could anticipate, so nobody should be allowed to use Pi in this way. It doesn't fit the definition. Fortunately, mathematicians and scientists are more open minded than that: they realize that powerful concepts take on a life of their own, and find many use cases far afield from their original intent. The same is true of software. Tools are generally conceived for particular use cases, but a truly excellent tool transcends those and goes far beyond the original intent of its designer. But if someone places unnatural restrictions on what the tool is allowed to do simply because they cannot conceive of a use case beyond some arbitrary boundary, the excellence of the tool will be abridged. One of the reasons I admire the Bell Labs pioneers so much is that they really understood this basic principle of software excellence. --- John Doty Noqsi Aerospace, Ltd.

Re: gEDA-user: Disposing of Etch Solution
Do you mean muriatic acid and hydrogen peroxide? Those are not hazardous chemicals, if they are neutralized. The hydrogen peroxide is easy to neutralize; just put a piece of charcoal in the bottle and it should decompose. Exposing it to sunlight will also work. Muriatic acid could be harder, depending on the concentration. You just need to react it with base. Sodium bicarbonate, ammonia, and powdered drain cleaner are all readily available bases. But if the acid is highly concentrated, you will need to mix carefully because the reaction is exothermic. First pour water into a container, then mix in a calculated amount of base, then slowly pour in the acid. I don't know the relevant environmental regs, but I'm sure that at pH 5-9 those chemicals should be safe for any sewer. Are the muriatic acid and H2O2 already mixed together? I don't think that H2O2 has an adverse reaction with most bases. NaOH will probably just catalyze its decomposition. But IANAC (I am not a chemist).

Re: gEDA-user: Disposing of Etch Solution
The whole point of HCl/H2O2 solution is that you *dont* have to discard it. Over time, it grows into a CuCl etchant which is air regenerated and shelf stable. Otherwise, mix NaOH slowly until the solution turns from clear green to opaque white.

Re: gEDA-user: Disposing of Etch Solution
Yes, it's very easy to make H2O2 decompose. Activated carbon does it very quickly, but charcoal works too. Just don't use charcoal briquettes imbued with lighter fluid!. And if your sink is getting damaged, I would guess that the problem is too much base, not too much H2O2. Strong bases can etch stainless steel. And yes DJ is correct that the copper precipitate would be hazardous waste. When I first replied to Rob, I thought that he meant surplus solution, not used solution.

gEDA-user: gnucap, hspice output - python
There have been a few python-based tools for analysis of simulation data
posted here, e.g. oscopy and dataplot. Here is another to
complement them.
To use python and numpy's arrays as the working format for signal
analysis requires conversion or import from a simulator's usual output.
Current gnucap output is an easy-to-read ascii format with
numpy.genfromtxt().
Converting HSPICE output is a different story... There are several out
there but I have settled on the sp2sp utility from gwave as it can
output an ascii format, again read into python via numpy.genfromtxt().
All this is great until (#files * size-each) gets large (GB in one of my
usage cases). Using sp2sp + numpy.genfromtxt results in files being
read twice, written once, then read entirely into RAM as a numpy.array.
This gets slow.
Solution: cache the data in a .npy file. It's a binary format and,
most importantly, allows numpy to memory-map the data. Caching the data
(for memmap read) does not allow other metadata in the file like column
headers and sweep variables/values. This must be saved separately to
re-read the data.
Enter pyspice.spicereader and an extension to sp2sp:
The gwave branch guile-gnome-platform-branch rev 245 patch now
includes an option to directly convert to a .npy file with a trick to
include metadata.
Usage is:
sp2sp -t ascii -c numpy -o out_file.npy in_file.dat
sp2sp -t hspice -c numpy -o out_file.npy in_file.tr0
The resulting .npy file has extra bytes appended to the normal
numpy.save() file: a string representation of a dict of column labels
and sweep info, ending in a little endian uint16 giving the length of
the appended info.
The attached numpy2ascii.py gives an example how to read the file by
converting the data back to the gnucap ascii format.
My module pyspice.spicereader presents the data as named attributes and
makes sweep handling and plotting easy. Now I can do:
from pylab import *
from pyspice.spicereader import loadSimData
d = loadSimData('channel.tr0')
print d.siglist
plot(d.x, d.Ivsupply)
loadSimData caches the data by running sp2sp and mem-maps the file which
makes subsequent reads very fast.
The spicereader.py is part of my pyspice project (but not dependent
on other parts of it). The pyspice module was written to cleanup LVS
extracted layouts for simulation, it likely does not work as-is; I
haven't used it for a few years.
Repeat: this requires the SVN branch guile-gnome-platform-branch of
gwave's utility sp2sp.

Oops, here's the example.
Some day (tm) I'll make a gnucap plugin to output directly to this

sp2sp -c numpy output format
Numpy array data is same as sp2sp -c nohead -s prepend. File is in the
numpy.save('file.npy') version 1.0, documented in numpy/lib/format.py with
additional information immediately following the binary data.
Footer is a python string representation of a dict ending in a newline with
the following keys:
'sweepvars' - Tuple of strings naming the sweep variables in order,
empty tuple if no sweeps.
e.g. ('bias', 'foo', 'bar') or ()
'sweeprows' - Tuple of 2-element tuples indicating the start and end row
indices of each table. A 3-D array doesn't work because each
sweep may have different number rows.
e.g.((0, 20), (21, 40))
'cols' - Tuple of strings labeling the columns. The first elements should
match the elements of 'sweepvars'.
e.g. ('bias', 'TIME', '0', 'v(foo', ... )
After the newline byte, the last two bytes are the footer length (including
these bytes) in uint16 little endian format. See below for the two ways of
reading the footer while using numpy.load('spiceout.npy').
import os
import sys
import struct
import numpy as np
from numpy.lib.utils import safe_eval
npfile = sys.argv[1]
npasciifile = sys.argv[2]
ndigits = 6
# 2 ways to use np.load
# -read into memory
# -open as mem-mapped file
# read array into memory
if 0:
fnp = open(npfile, 'rb')
npdata = np.load(fnp)
# when given an open file handle, np.load leaves the pointer just after
# the data (which is the start of the footer, conveniently). The footer's
# newline makes this really easy:
footer = fnp.readline()
# open as a memory-mapped array on disk (preferred for large data)
else:
# At present, the memmap versions of np.load require a filename string and
# do not accept an open file-like object. (Though
# np.lib.format.open_memmap and np.memmap look like this is not truly
# the case)
# Peek at the end of the file and use the footer len bytes to put the
# pointer at the start of the footer string
fnp = open(npfile, 'rb')
fnp.seek(-2, os.SEEK_END)
footlen = struct.unpack('H', fnp.read(2))[0]
print 'footlen:', footlen
fnp.seek(-footlen, os.SEEK_END)
footer = fnp.readline()
print 'footer:', footer
fnp.close()
# NOW, open file using the name string and pretend we didn't take a peek...
npdata = np.load(npfile, 'r') #read only memmap
# get dict from the string, without accidentally exec'ing bad stuff
npinfo = safe_eval(footer)
print 'npinfo:', npinfo
# gen column headers
header = list(npinfo['sweepvars'])
header.extend(npinfo['cols'])
fnpa = open(npasciifile, 'wb')
printfnpa, ' '.join(header)

gEDA-user: git based wiki
Hi guys, Recall there was some chat about git backed wiki software? I came across this one today: https://github.com/github/gollum It is what github use, and supports several markup formats. The software is written in ruby I believe. PS.. try some of the file links in the github site.. Very very sexy web-2.0 AJAX goodness there ;) -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)

Good question. This was done long ago. On this note, what is the recommended file naming convention for footprints? Do you use the .fp extension? You can get away with it (I think), if you don't use any (actual) M4 symbols, and you pass the --skip-m4 option to gnetlist, or put skip-m4 inside the project file. I'll just fix the directory name. Should I just move the contents of packages/m4 to packages/newlib (or perhaps just packages/)?

Ahhh. That would explain it. Those packages came from http://www.luciani.org/geda/pcb/pcb-footprint-list.html. Are none of these correctly named? John's library doesn't use m4, so if you're using his library, you should disable m4. Then you don't have the problem. On this note, what is the recommended file naming convention for footprints? Do you use the .fp extension? Yes. File-based footprints should be named *.fp ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
