Re: Improve Python + Influxdb import performance

[Prathamesh]

Hi

I've installed Jython 2.7 and was able to get weblogic running as a Jython 2.7 
module following
https://technology.amis.nl/2015/10/04/how-to-use-wlst-as-a-jython-2-7-module/

I got the requests module 2.7 installed as well

But am facing an issue when invoking it
related to SSL certificates
and to stop those errors I think you need utillib2/utillib3
and that has dependencies
one of which is cryptography - which is a real pain to install

Any pointers on this
or easier way to install this?
I'm running Windows 2008R2

Also my pip install doesn't work
I get geteid error

Please let me know

Thanks
P

It's a personal thing but not a toy. Some more info here:

Click on the 'Q Features' link, this includes a selection of built-in

(enumerations, records etc) which Python seems to have trouble with.


(And it can't have simple enumerations such that cat=1, dog=2, but needs 
to have every conceivable embellishment. In other words it doesn't know 
how to keep things simple.)


(To actually run this, there still appears to be a file 'pcc.c' at the 
top level of that github project. This is an old C version of the

just now. You need a 32-bit C compiler. I had to remove a binary version 
(for Windows) when someone said github doesn't allow binaries.)



For all the hype about GvR's "supposed" time machine, we can
see that Python has suffered some major design flaws. And
since Python3000, feature creep has been churning into
overdrive.


Yes. I suppose when it gets to a point where there are so many features 
anyway, adding a few more makes little difference!

RE: Swiss Ephemeris

[Adriaan Renting]

There are at least two other packages with Python bindings that allow
ephimerides calculations.

1) PyEphem http://rhodesmill.org/pyephem/
2) Pyraphttp://www.astron.nl/casacore/trunk/pyrap/docs/ (This needs a
very big casacore c++ library and thus a pain to compile, but can give
second level accuracy if you use updated IERS tables).

As to the ancient's (Greek/Roman) nature philosophy. We still use some
of it today, especially in the fields of mathematics, mechanics and
observational astronomy, but their understanding of biology and
especially the human body was entirely incorrect.

Western/Islamic medicine largely followed Hippocrates for nearly 2000
years (although the ideas are originally from Indian Ayurveda) and some
of the methods had some merit, but overall the treatments were often
worse than the disease, for example George Washinton was almost
certainly killed by his doctors.
Only with the application of the scientific method to medicine after
the enlightenment have we started to make any real progress. The most
important of which is blind trials in which a treatment needs to show to
be better than a placebo.

One of the most important things that modern medicine has shown is that
a placebo can have a real effect and cure people. Some people do get
better after you give them a sugar pill or its equivalent.
As humans we're also very good at seeing correlation and causation when
none might exist. Matt Parker has a very entertaining talk about this
here https://www.youtube.com/watch?v=sf5OrthVRPA

P.S. I had an uncle who died of cancer 2 years ago who was a firm
believer in all kinds of non-mainstream cures and tried all kinds of
alternative cures from accupuncture to yoga to Gc-MAF. In the end the
only results I saw were that these people got many 10.000s euros from
him and he died very disillusioned and poor as these were not covered by
his health insurance. I learned a lot about magazines like "What doctors
don't tell you" - which use the images of people in white labcoats to
sell you things that doctors don't tell you about because they are known
to be ineffective or even bad for you. I understand that a lot of people
have a problem with authority and/or look for alternatives if mainstream
medicine can't help them. And sometimes the methods seem to work and
those are the stories you hear, as the other people end up like my
uncle, who's not here any more to tell his story. Don't end up like my
uncle.

Agree. python is python and I suppose that performance issues
has much to do with types and OOP.
When I first started with python I thought - no, it is not possible
without types, if I'll write something more complicated than
hello world, it will all break at some point.
But hell, this works and works good.

Still I miss some old school features in Python, e.g. "goto" statement would
be very useful in some cases. I know it is considered bad style
to use goto, but in some cases it is just most natural thing to use.

What I am (and probably many people) missing is a good tool for
performance middle- and low-level applications.
For me it would be a coding tool, sort of minimalist IDE, with simple
readable syntax which generates compilable C code.
And it would not be necessarily python-like syntax,
but I tend to agree that for today python's syntax is
most readable.

The problem that many are overlooking still is that the
possibilities for syntaxes are very limited in pure text-mode
presentation.

[ANN] txAWS 0.3.0

[Jean-Paul Calderone]

Hello all,

I'm pleased to announce the release of txAWS 0.3.0.  txAWS is a library for
interacting with
Amazon Web Services (AWS) using Twisted.

You can download the release from PyPI 
 (https://pypi.python.org/pypi/txAWS).

txAWS development uses GitHub for issues and source control
 (https://github.com/twisted/txaws).

Since the last release, the following enhancements have been made:

   - Jean-Paul Calderone added basic Route53 support.
   - Mark Williams add Auth v4, now used by the S3 and Route53 support.
   - Francisco Souza added support for VPCs to some EC2 APIs.
   - Drew Smathers added multi-part S3 upload support.
   - Several people added other S3 client features such as pagination and
   streaming uploads.
   - *txaws.testing* now provides S3 and Route53 support.

Additionally, the following APIs have been deprecated:

   - The *client* attribute of *txaws.client.base.BaseQuery*
   - The *date* attribute of *txaws.s3.client.Query*

Thanks to everyone who contributed and to Least Authority Enterprises
 () for
sponsoring my work on this release.

I don't know much about that library. What does its documentation say
for the ‘table.to_csv’ function?

Can you write a *very short* complete example, that we can run to
demonstrate the same behaviour you are seeing?

> an error message persists as follows:

> 0: ordinal not in range(128)

This means the function has been told (or is assuming, in the absence of
better information) that the input data is in the ‘ascii’ text encoding.

That assumption turns out to be incorrect, for the actual data you have.
So that error occurs.

You will need to:

* Find out exactly what text encoding was used to write the file. Don't
  guess, because there are many ways to be wrong.

* Specify that encoding to the ‘table.to_csv’ function, or to whatever
  function opens the file. (This might be the Python built-in ‘open’
  function, but we'd need to see your short example to know.)

The default encoding in Python 2 is ascii, and the pound sign is not part of 
that.

> Can anyone help?

Specify an alternative encoding, preferably UTF-8:

>>> import pandas
>>> df = pandas.DataFrame([[u"\xa3123"], [u"\xa3321"]], columns=["Price"])
>>> df
  Price
0  £123
1  £321

[2 rows x 1 columns]
>>> df.to_csv("tmp.csv", encoding="utf-8")

$ cat tmp.csv
,Price
0,£123
1,£321

There is no "pound sign" in ASCII[1]. Try changing your target encoding to 
something other than ASCII.

Re: using HTTPHandler cause Django server side shows http 400 and Invalid HTTP_HOST header message

I am sure !

As I have tested: If I pass the IP address of my web server to the host 
parameter of HTTPHandler, the server side would show http 400 and Invalid 
HTTP_HOST header message  , while if I pass the domain name instead, then the 
view function works as expected . 
 
would it be a bug within HTTPHandler?

Re: Need help with getting Key, Value out of dicts in lists

[John Ralph]

There are a number of ways to reorganise the data for the exclusive use of your 
script without affecting the original data.  Is there a reason you can't or not 
allowed to do this?

Regardless, here's some code that might make things a little easier.  It 
operates on each balancer on the fly, reduces the number of for loops, and 
eliminates worries about where the tags are placed within the list.

from operator import itemgetter

alist = \
[
[
{u'Value': 'shibboleth-prd', u'Key': 'Name'},
{u'Value': 'kvmu', u'Key': 'Billing'},
{u'Value': '20179204-181622543367489', u'Key': 'Resource_group_id'}
],
[
{u'Value': '20172857-152037106154311', u'Key': 'Resource_group_id'},
{u'Value': 'shibboleth-tst', u'Key': 'Name'}
]
]

# Problem:
# for all resource group id tags that equal '20172857-152037106154311':
#   print its name tag (eg, "shibboleth-prd-alb")

# create a container (dict) of tags for each balancer on the fly
for balancer in alist:
tags = dict(map(itemgetter('Key', 'Value'), balancer))
print 'group of tags:', tags
if itemgetter('Resource_group_id')(tags) == '20172857-152037106154311':
print '\tfound resource, resource name:', itemgetter('Name')(tags)

[ANN] txkube 0.1.0

[Jean-Paul Calderone]

Hello all,

I'm pleased to announce the first release of txkube, a Twisted-based
library for interacting with Kubernetes using the HTTP API.

This release supports several of the most commonly used basic Kubernetes
objects, including Services, ConfigMaps, Deployments, ReplicaSets, and
Pods.  While Kubernetes has many, many more object kinds, this collection
of kinds already supports a very useful set of interactions.

Here is an example of txkube usage, taken from the README:

   from __future__ import print_function
   from twisted.internet.task import react

   from txkube import v1, network_kubernetes_from_context

   @react
   def main(reactor):
   k8s = network_kubernetes_from_context(reactor, u"minikube")
   client = k8s.client()
   d = client.list(v1.Namespace)
   d.addCallback(print)
   return d

You can download txkube from PyPI .
You can contribute to its development on GitHub
.

Thanks to Least Authority Enterprises  for
sponsoring this development.

Re: Swiss Ephemeris

[Peter Henry]

Hi Deborah,

Thanks your reply and interest,

A few years ago did create a Excel addin, that extracted planetary
coordinates from the Swisseph source code and populated excel spreadsheet
 This Marco addin had customised planetary settings of which was  useful

Currently now learning to program in Python as it  is flexible, popular
 for machine learning and data science. The idea the planetary coordinate
can help with timing stock commodity and Forex markets, as both freely
trading markets and planetary  movement adhere to natural law

Neural networks can also assist in extracting relationship information
between markets and planetary positions.

Whilst waiting for a solution  can you advise of an efficient way of
producing a a CSV file similar to the file attached, only planetary data
required


Many thanks

Peter

RE: Swiss Ephemeris

[Deborah Swanson]

Hi Peter,

I would be interested in seeing your Excel addin with customized
planetary settings. I'd be curious what these customizations would be,
though if they look useful I'd more likely be scavenging the code to
rewrite it in Python and add to what I already have, rather than using
the addin in Excel. The only thing not quite right about what I have is
the times, which are a smidge off. This could be due to planetary
anomalies, so I definitely would like to look at it.

I totally agree with all you said about Python and more. I didn't start
out in Python looking to replace Excel or to migrate my planetary
project to it, those things just happened along the way. But looking
around to see what was new and what was better than anything I'd done
before, Python was a natural choice.

I'll have to say though that I don't share your enthusiasm for modeling
the market with planetary relationships, indeed any mathematical
modelling of the market can easily be overall wrong, and yet complex
enough to engage the explorer endlessly. 

I've analyzed a couple of these schemes to draw that conclusion, though
it's tentative at best. Obviously there are mathematical models of the
market that do work, but I really don't know anything about them. 

In this case though, I don't see the connection between planetary
configurations and a pure physical aspect of the market for them to
engage with. And as you may recall from somewhere, to establish
causality you must produce the causal link between the two sets of
events you're attempting to correlate. No matter how stunning an array
of coincidences might be, without producing the causal link you really
don't have anything. This is a key error that many who do statistical
analyses tend to overlook.

I looked at your CSV, but I'm not sure what you would like to add to it,
probably because I'm totally unfamiliar with this type of project. 

Best in your endeavors,

Deborah

I've also worked on the problem of getting sweph into Python and have
mostly struck out so far myself.

I found one reliable means to get sweph's planetary data into Python,
but it's more or less a cheat. Nonetheless, if you want to see how much
good it does you, try the Swiss Ephemeris Test Page at
http://www.astro.com/swisseph/swetest.htm. If you can successfully
formulate a query useful to your purposes, you can download a csv of
results, read it into Python, and work from there. Right now I'm working
on converting some Excel spreadsheets and Excel VBA I use into Python
and recoding it all, using the CSVs for jumping off points. That works
pretty well, except the times from swetest are off a bit and I haven't
figured out why. But I'm concentrating on getting all my VBA code ported
to Python, and will go back to getting bang on data from sweph after I
have my code done.

The first thing I tried was to get sweph's C source code into a free
IDE, but that whole project went down in flames. You can read bits and
pieces of that misadventure at the tail end of the "Python application
launcher (for Python code)" thread. I found sweph's C source code at
some link off "Programming interface to the Swiss Ephemeris" at
http://www.astro.com/swisseph/swephprg.htm (or maybe it was on
http://www.astro.com/swisseph/swephinfo_e.htm - I can't easily find it
now, but the download link is in one of those two pages somewhere.)

Then I tried picking through sweph's C source code, attempting to
manually reproduce the logic and the calculations in Python. That was a
highly qualified semi-success because the times were still off, but it
essentially produces the most basic planetary data. The swetest output

Hi Deborah

Very few people would believe there is correlation between planetary cycles
and the stockmarket  however this is known to select few, for many years, I
can also visually see relationship on charts, however its hard to quantify
statically

http://astrologynewsservice.com/business/study-confirms-plan
ets-impact-stock-market-averages/

I'll forward the Excel addin later it works on Windows 7 and require
updating to Win10

The idea is to create a full and complete program in Python only, that
would import stock data, generate planetary coordinates, pre process train
then predict

I'll keep you updated

Peter

RE: Swiss Ephemeris

[Deborah Swanson]

Hi Peter

I'm willing to believe there's a correlation between planetary cycles
and the stockmarket, if you say you see one. The question is whether
this correlation has truth value significance, or whether it's just a
set of coincidences. 

The correlation is interesting, but I fail to see the causal link, the
reason why planetary cycles necessarily have a relationship with market
movements, and without that all you have is coincidence. 

Though one could spend a great deal of time analyzing the correlation, I
have low confidence that it would be a strong and reliable correlation.
This has been the fate of many other misadventures in astrology, systems
of belief built around weak and unreliable correlations that are
sometimes right, but more often wrong, sad to say.

I don't have Windows 7 or 10. Any chance there's source code for the
addin? That's what I would be looking at anyway. ;)

Best,
Deborah

John, where does your "apelist.txt" file come from? Who has decided what 
format it should be in?


If *you* get to decide that, then the best thing to do is to specify a 
format that is easy to read in in the first place - rather than 
specifying something that looks like source code and then has to be parsed.


E.g., if the file had the format:

Home sapiens
Pan troglodytes
Gorilla gorilla

(i.e., each value on a separate line with no quotes or any other 
"noise"), then the code to read that in as you have indicated you want 
is something like:


for i in open("apefile.txt").readlines():
print("one of the apes is " + i.rstrip())

(the .rstrip() is to remove the trailing newline character - and any 
other trailing whitespace - which readlines() will include in what it 
returns).


Of course, if you don't have any control over the input file's format, 
then it looks like you (or something you delegate to) will have to do 
some sort of parsing.

If he does, it might be the final thing that gets him banned from the

Please don't encourage the use of old legacy encodings.

In 2017, unless you are reading from old legacy files created using a
non-Unicode encoding, you should just use UTF-8.

Heck, you can write an exec() function for C if you really
want. Run the C compiler in another process, dynamically
load the object file and call it. Doing that would be very
inefficient, but it wouldn't slow down the rest of your

Actually, this thing exists and it is quite useful. tcc can be used as a 
library / JIT compiler for C. It does allow both writing to a dynamic 
library as well as creating callable functions in memory.


https://github.com/LuaDist/tcc/blob/master/libtcc.h#L64

What you can't do with it, however, is access to local variables. i.e. 
writing an exec which does this:


int i=0;
exec("i = 5");
printf("%d", i); // prints 5

is impossible in C, and making it possible (via debug symbols, e.g.) 
would make the program slower, because C compilers reorder the 
instructions and assign variables to registers.
