"""
werkzeug.serving
~~~~~~~~~~~~~~~~
There are many ways to serve a WSGI application. While you're developing
it you usually don't want a full blown webserver like Apache but a simple
standalone one. From Python 2.5 onwards there is the `wsgiref`_ server in
the standard library. If you're using older versions of Python you can
download the package from the cheeseshop.
However there are some caveats. Sourcecode won't reload itself when
changed and each time you kill the server using ``^C`` you get an
`KeyboardInterrupt` error. While the latter is easy to solve the first
one can be a pain in the ass in some situations.
The easiest way is creating a small ``start-myproject.py`` that runs the
application::
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from myproject import make_app
from werkzeug.serving import run_simple
app = make_app(...)
run_simple('localhost', 8080, app, use_reloader=True)
You can also pass it a `extra_files` keyword argument with a list of
additional files (like configuration files) you want to observe.
For bigger applications you should consider using `werkzeug.script`
instead of a simple start file.

This page is in the table of contents.
The gts.py script is an import translator plugin to get a carving from an gts file.
An import plugin is a script in the interpret_plugins folder which has the function getCarving. It is meant to be run from the interpret tool. To ensure that the plugin works on platforms which do not handle file capitalization properly, give the plugin a lower case name.
The getCarving function takes the file name of an gts file and returns the carving.
The GNU Triangulated Surface (.gts) format is described at:
http://gts.sourceforge.net/reference/gts-surfaces.html#GTS-SURFACE-WRITE
Quoted from http://gts.sourceforge.net/reference/gts-surfaces.html#GTS-SURFACE-WRITE
"All the lines beginning with GTS_COMMENTS (#!) are ignored. The first line contains three unsigned integers separated by spaces. The first integer is the number of vertexes, nv, the second is the number of edges, ne and the third is the number of faces, nf.
Follows nv lines containing the x, y and z coordinates of the vertexes. Follows ne lines containing the two indices (starting from one) of the vertexes of each edge. Follows nf lines containing the three ordered indices (also starting from one) of the edges of each face.
The format described above is the least common denominator to all GTS files. Consistent with an object-oriented approach, the GTS file format is extensible. Each of the lines of the file can be extended with user-specific attributes accessible through the read() and write() virtual methods of each of the objects written (surface, vertexes, edges or faces). When read with different object classes, these extra attributes are just ignored."
This example gets a carving for the gts file Screw Holder Bottom.gts. This example is run in a terminal in the folder which contains Screw Holder Bottom.gts and gts.py.

Heaps are arrays for which a[k] <= a[2*k+1] and a[k] <= a[2*k+2] for

non-existing elements are considered to be infinite. The interesting
property of a heap is that a[0] is always its smallest element.
Usage:
heap = [] # creates an empty heap
heappush(heap, item) # pushes a new item on the heap
item = heappop(heap) # pops the smallest item from the heap
item = heap[0] # smallest item on the heap without popping it

# new item; the heap size is unchanged
Our API differs from textbook heap algorithms as follows:
- We use 0-based indexing. This makes the relationship between the
index for a node and the indexes for its children slightly less
obvious, but is more suitable since Python uses 0-based indexing.
- Our heappop() method returns the smallest item, not the largest.
These two make it possible to view the heap as a regular Python list
without surprises: heap[0] is the smallest item, and heap.sort()
maintains the heap invariant!
"""
# Original code by Kevin O'Connor, augmented by Tim Peters and Raymond Hettinger
__about__ = """Heap queues
[explanation by François Pinard]
Heaps are arrays for which a[k] <= a[2*k+1] and a[k] <= a[2*k+2] for
all k, counting elements from 0. For the sake of comparison,
non-existing elements are considered to be infinite. The interesting
property of a heap is that a[0] is always its smallest element.
The strange invariant above is meant to be an efficient memory
representation for a tournament. The numbers below are `k', not a[k]:
0
1 2
3 4 5 6
7 8 9 10 11 12 13 14
15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
In the tree above, each cell `k' is topping `2*k+1' and `2*k+2'. In
an usual binary tournament we see in sports, each cell is the winner
over the two cells it tops, and we can trace the winner down the tree
to see all opponents s/he had. However, in many computer applications
of such tournaments, we do not need to trace the history of a winner.
To be more memory efficient, when a winner is promoted, we try to
replace it by something else at a lower level, and the rule becomes
that a cell and the two cells it tops contain three different items,
but the top cell "wins" over the two topped cells.
If this heap invariant is protected at all time, index 0 is clearly
the overall winner. The simplest algorithmic way to remove it and
find the "next" winner is to move some loser (let's say cell 30 in the
diagram above) into the 0 position, and then percolate this new 0 down
the tree, exchanging values, until the invariant is re-established.
This is clearly logarithmic on the total number of items in the tree.
By iterating over all items, you get an O(n ln n) sort.
A nice feature of this sort is that you can efficiently insert new
items while the sort is going on, provided that the inserted items are
not "better" than the last 0'th element you extracted. This is
especially useful in simulation contexts, where the tree holds all
incoming events, and the "win" condition means the smallest scheduled
time. When an event schedule other events for execution, they are
scheduled into the future, so they can easily go into the heap. So, a
heap is a good structure for implementing schedulers (this is what I
used for my MIDI sequencer :-).
Various structures for implementing schedulers have been extensively
studied, and heaps are good for this, as they are reasonably speedy,
the speed is almost constant, and the worst case is not much different
than the average case. However, there are other representations which
are more efficient overall, yet the worst cases might be terrible.
Heaps are also very useful in big disk sorts. You most probably all
know that a big sort implies producing "runs" (which are pre-sorted
sequences, which size is usually related to the amount of CPU memory),
followed by a merging passes for these runs, which merging is often
very cleverly organised[1]. It is very important that the initial
sort produces the longest runs possible. Tournaments are a good way
to that. If, using all the memory available to hold a tournament, you
replace and percolate items that happen to fit the current run, you'll
produce runs which are twice the size of the memory for random input,
and much better for input fuzzily ordered.
Moreover, if you output the 0'th item on disk and get an input which
may not fit in the current tournament (because the value "wins" over
the last output value), it cannot fit in the heap, so the size of the
heap decreases. The freed memory could be cleverly reused immediately
for progressively building a second heap, which grows at exactly the
same rate the first heap is melting. When the first heap completely
vanishes, you switch heaps and start a new run. Clever and quite
effective!
In a word, heaps are useful memory structures to know. I use them in
a few applications, and I think it is good to keep a `heap' module
around. :-)
--------------------
[1] The disk balancing algorithms which are current, nowadays, are
more annoying than clever, and this is a consequence of the seeking
capabilities of the disks. On devices which cannot seek, like big
tape drives, the story was quite different, and one had to be very
clever to ensure (far in advance) that each tape movement will be the
most effective possible (that is, will best participate at
"progressing" the merge). Some tapes were even able to read
backwards, and this was also used to avoid the rewinding time.
Believe me, real good tape sorts were quite spectacular to watch!
From all times, sorting has always been a Great Art! :-)

#
# We *could* break out of the loop as soon as we find a pos where newitem <=
# both its children, but turns out that's not a good idea, and despite that
# many books write the algorithm that way. During a heap pop, the last array
# element is sifted in, and that tends to be large, so that comparing it

"""
This is an implementation of decimal floating point arithmetic based on
the General Decimal Arithmetic Specification:
http://speleotrove.com/decimal/decarith.html
and IEEE standard 854-1987:
http://en.wikipedia.org/wiki/IEEE_854-1987
Decimal floating point has finite precision with arbitrarily large bounds.
The purpose of this module is to support arithmetic using familiar
"schoolhouse" rules and to avoid some of the tricky representation
issues associated with binary floating point. The package is especially
useful for financial applications or for contexts where users have
expectations that are at odds with binary floating point (for instance,
in binary floating point, 1.00 % 0.1 gives 0.09999999999999995 instead
of 0.0; Decimal('1.00') % Decimal('0.1') returns the expected
Decimal('0.00')).
Here are some examples of using the decimal module:
>>> from decimal import *
>>> setcontext(ExtendedContext)
>>> Decimal(0)
Decimal('0')
>>> Decimal('1')
Decimal('1')

Decimal('123456')
>>> Decimal('123.45e12345678')
Decimal('1.2345E+12345680')
>>> Decimal('1.33') + Decimal('1.27')
Decimal('2.60')
>>> Decimal('12.34') + Decimal('3.87') - Decimal('18.41')
Decimal('-2.20')
>>> dig = Decimal(1)
>>> print(dig / Decimal(3))
0.333333333
>>> getcontext().prec = 18
>>> print(dig / Decimal(3))
0.333333333333333333
>>> print(dig.sqrt())

# answer), or "None" if we don't expect a certain answer and are just
# comparing the behavior of the nodes being tested.
# - the third value is the hash to test the tip against (if None or omitted,
# use the hash of the block)

# just added to the block_store. This is to facilitate block delivery
# when communicating with headers-first clients (when withholding an
# intermediate block).

# will be synced across all connections, and the outcome of the final
# block will be tested.

script_info['script_description'] = """
This script compares the alpha diversity of samples found in a collated alpha
diversity file. The comparison is done not between samples, but between groups
of samples. The groupings are created via the input category passed via
-c/--category. Any samples which have the same value under the catgory will be
grouped.
For example, if your mapping file had a category called 'Treatment' that
separated your samples into three groups (Treatment='Control', Treatment='Drug',
Treatment='2xDose'), passing 'Treatment' to this script would cause it to
compare (Control,Drug), (Control,2xDose), (2xDose, Drug) alpha diversity
values. By default the two-sample t-test will be nonparametric (i.e. using
Monte Carlo permutations to calculate the p-value), though the user has the
option to make the test a parametric t-test.
The script creates an output file in tab-separated format where each row is a
different group comparison. The columns in each row denote which two groups of
samples are being compared, as well as the mean and standard deviation of each
group's alpha diversity. Finally, the t-statistic and p-value are reported for
the comparison. This file can be most easily viewed in a spreadsheet program
such as Excel.
Note: Any iterations of a rarefaction at a given depth will be averaged. For
instance, if your collated_alpha file had 10 iterations of the rarefaction at
depth 480, the scores for the alpha diversity metrics of those 10 iterations
would be averaged (within sample). The iterations are not controlled by this
script; when multiple_rarefactions.py is called, the -n option specifies the
number of iterations that have occurred. The multiple comparison correction
takes into account the number of between group comparisons. If you do not know
the rarefaction depth available or you want to use the deepest rarefaction
level available then do not pass -d/--depth and it will default to using the
deepest available.
If t-statistics and/or p-values are None for any of your comparisons, there are
three possible reasons. The first is that there were undefined values in your
collated alpha diversity input file. This occurs if there were too few
sequences in one or more of the samples in the groups involved in those
comparisons to compute alpha diversity at that depth. You can either rerun
%prog passing a lower value for --depth, or you can re-run alpha diversity
after filtering samples with too few sequences. The second is that you had some
comparison where each treatment was represented by only a single sample. It is
not possible to perform a two-sample t-test on two samples each of length 1, so
None will be reported instead. The third possibility occurs when using the
nonparamteric t-test with small datasets where the Monte Carlo permutations
don't return a p-value because the distribution of the data has no variance.
The multiple comparisons correction will not penalize you for comparisons that
return as None regardless of origin.
If the means/standard deviations are None for any treatment group, the likely
cause is that there is an \'n\\a\' value in the collated_alpha file that was
passed.

========================================================
Topics extraction with Non-Negative Matrix Factorization
========================================================
This is a proof of concept application of Non Negative Matrix
Factorization of the term frequency matrix of a corpus of documents so
as to extract an additive model of the topic structure of the corpus.
The output is a list of topics, each represented as a list of terms
(weights are not shown).
The default parameters (n_samples / n_features / n_topics) should make
the example runnable in a couple of tens of seconds. You can try to
increase the dimensions of the problem, but be aware than the time complexity
is polynomial.

vaporry/dapp-bin | serpent_gamble/prepare.py | 5 | 2914 | # This is an ultra-minimal "dapp framework" that simplifies the deployment
# process by generating a config.js file that specifies the ABI for all of
# the contracts that you need and also includes the ability to update
# addresses. By default, it simply scans through every .se and .sol file in
# the current directory and adds and ABI object for each one into a JS
# object stored under window.accounts, with the key of each ABI object being
# the filename noc including the .se/.sol ending. For example, wallet.sol
# will create window.accounts.wallet = { abi: ... }
#
# You can also use the x=y syntax to set an address. For example, if you
# call python prepare.py admin=0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae,
# then in the JS object you will get window.accounts.admin =
# '0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae'; this persists if you call
# python prepare.py after without setting the argument again as the script
# always tries to read the value set from the previous time the config.js
# file was created.
#
# Example use:
#
# Step 1: serpent compile currency.se
# Step 2: in eth/geth/pyeth, send a transaction to create a contract whose
# code is the output of the previous line
# Step 3: get the contract address of the contract you created. Suppose that
# this address is 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae
# Step 4: run
# python prepare.py currency=0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae

self.cur is always a tuple. Each such tuple corresponds to a stack
frame that is currently active (self.cur[-2]). The following are the
definitions of its members. We use this external "parallel stack" to
avoid contaminating the program that we are profiling. (old profiler
used to write into the frames local dictionary!!) Derived classes
can change the definition of some entries, as long as they leave
[-2:] intact (frame and previous tuple). In case an internal error is
detected, the -3 element is used as the function name.
[ 0] = Time that needs to be charged to the parent frame's function.
It is used so that a function call will not have to access the
timing data for the parent frame.
[ 1] = Total time spent in this frame's function, excluding time in
subfunctions (this latter is tallied in cur[2]).
[ 2] = Total time spent in subfunctions, excluding time executing the
frame's function (this latter is tallied in cur[1]).
[-3] = Name of the function that corresponds to this frame.
[-2] = Actual frame that we correspond to (used to sync exception handling).
[-1] = Our parent 6-tuple (corresponds to frame.f_back).
Timing data for each function is stored as a 5-tuple in the dictionary
self.timings[]. The index is always the name stored in self.cur[-3].
The following are the definitions of the members:
[0] = The number of times this function was called, not counting direct
or indirect recursion,
[1] = Number of times this function appears on the stack, minus one
[2] = Total time spent internal to this function
[3] = Cumulative time that this function was present on the stack. In
non-recursive functions, this is the total execution time from start
to finish of each invocation of a function, including time spent in
all subfunctions.
[4] = A dictionary indicating for each function name, the number of times
it was called by us.

#******************************************************************
# The following calculates the overhead for using a profiler. The
# problem is that it takes a fair amount of time for the profiler
# to stop the stopwatch (from the time it receives an event).
# Similarly, there is a delay from the time that the profiler
# re-starts the stopwatch before the user's code really gets to
# continue. The following code tries to measure the difference on
# a per-event basis.
#
# Note that this difference is only significant if there are a lot of
# events, and relatively little user code per event. For example,
# code with small functions will typically benefit from having the
# profiler calibrated for the current platform. This *could* be
# done on the fly during init() time, but it is not worth the
# effort. Also note that if too large a value specified, then
# execution time on some functions will actually appear as a
# negative number. It is *normal* for some functions (with very
# low call counts) to have such negative stats, even if the
# calibration figure is "correct."
#
# One alternative to profile-time calibration adjustments (i.e.,
# adding in the magic little delta during each event) is to track
# more carefully the number of events (and cumulatively, the number
# of events during sub functions) that are seen. If this were
# done, then the arithmetic could be done after the fact (i.e., at
# display time). Currently, we track only call/return events.
# These values can be deduced by examining the callees and callers
# vectors for each functions. Hence we *can* almost correct the
# internal time figure at print time (note that we currently don't
# track exception event processing counts). Unfortunately, there
# is currently no similar information for cumulative sub-function
# time. It would not be hard to "get all this info" at profiler
# time. Specifically, we would have to extend the tuples to keep
# counts of this in each frame, and then extend the defs of timing
# tuples to include the significant two figures. I'm a bit fearful
# that this additional feature will slow the heavily optimized
# event/time ratio (i.e., the profiler would run slower, fur a very
# low "value added" feature.)
