Contrary to OP's original statement, this is not his
immediate problem. The multiple apps part seem
to work for him, but it seems that nginx redirections
are contrary to his expectations.

I do think it is off-topic: It really has to do with understanding
how the proxy_pass directive in nginx works, and i is not just
about being off-topic. I still think that you would get better
answers on a nginx list. The fact that nginx is proxying to a
Django application is irrelevant here. Nevertheless, I am
bored at the moment :-)

Your description points to a different issue: The problem is not
that there are multiple upstream servers (those seem to be
configured correctly, and should be working fine), but that you
are seeing what you feel to be an unexpected redirection.

[...]

I think that this the crux of the confusion: While I cannot
test this now, the above redirection should be as expected
from your configuration. Viz., with the configuration:

location /green/ {
proxy_pass  http://green_servers;
}

https://example.com/green/login should indeed redirect
to https://example.com/login

Maybe these links will help (I am unable to do more
without a test setup):
* nginx core documentation: Please read carefully the
  distinction between specifications with, and without
  a URI. Your /api and /green locations are different
  in this respect.
* Multiple examples of such configurations:
   http://www.liaohuqiu.net/posts/nginx-proxy-pass/

A final thing to watch out for is trailing-slashes in the
proxy-pass directive: The nginx behaviour here can
be quite confusing.

First of all, this is really off-topic here, and you are probably
better off asking
on a nginx list. Having said that, we regularly use nginx with
gunicorn, and what
you need to do is
* Set up an upstream server that defines the TCP/Unix domain socket that
  gunicorn is listening on. Something like:
   upstream app_server {
server 127.0.0.1:80 fail_timeout=0;
}
* Then, proxy to the app_server, e.g.,
   location @proxy_to_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header  X-Forwarded-Protocol https;
proxy_redirect off;
proxy_buffering off;
proxy_pass   http://app_server;
}

There are many detailed write-ups available by searching Google: See, e.g.,

Please show actual nginx configuration on the nginx mailing list rather than
pseudo-examples like this. Nobody can tell what you are actually trying.

That is hardly an excuse: By that token, I could discuss Debian/Ubuntu

as they make extensive use of Python for system tasks. Now, what would have been
on-topic would have been a discussion on how those plots were created
with Python,
and any special tricks that were use.

Hi,

With all due respect, your question is too vague for anyone to be able
to answer:
* You do not indicate which plotting library you are using. Without
that, how do you expect anyone to help you?

* Your first question is still vague: Of course, one can plot points
in the range 1e13 to 1e19 on a linear scale. The real question
probably is how to do this in a meaningful way, and that is probably
specific to your data. If you share some details, and show what you
have tried, people might be able to help you.

Somewhere you are getting too large a number for the range of type in
the array that you are using: probably because you are dividing by the
very small Boltzmann constant.

You either need to use a type with a bigger range, say bigfloat for
arbitrary precision floating-point arithmetic, or if the errors only
occur for values that can be ignored, see
http://docs.scipy.org/doc/numpy/reference/generated/numpy.seterr.html
for how to ignore errors.

Incidentally, all this information is available from an easy Google search.

Re: [BangPypers] Fwd: Need a help on reviewing a python code.

Hi,

Just forget it. The problem statement itself is so badly broken that
it is unfixable, IMHO. To quote from problem.txt:
The application will not determine the alignments itself. Instead, the
application must be able to load a set of plugins at runtime that will determine
whether a particular configuration of planets is 'aligned' according to whatever
definition the plugin uses for alignment.

Yes, and without the specification of an interface, I suppose Moses
will come down from the mountain to tell us how a  particular plugin
decides how a planet is alignedOh my God/aligned. IMHO, it is just
not worth even applying to such companies as their basic recruitment
process seems not to work.

Re: [BangPypers] UI less Rest API server with flask

[Gora Mohanty]

Hi,

Since you seem to be determined to reinvent the wheel, may I ask what is
your use case to choose flask + largely-roll-one's-own-rest-api vs. Django
+ DRF?

The same goes for all the recent hoopla in this list over Flask/Bottle over
Django, if you ask me. Django is not all that difficult to get into, has a
well-established track record, and is eminently scalable. For serious
development, one also needs to worry about the community size, and support.
I do not even know that Flask/Bottle/what have an edge over Django for any
use case, but IMHO if so one would be talking about the scale of one the
largest sites on the Internet. Remember, premature oprtimisation is the
root of all evil. Sorry, but if you ask me I smell buzzword-driven
development.

Gora

Dear Pramod,

This sounds great, and I think that it would be perfectly fine to
continue such a discussion on this list. At least until it gets into
nitty-gritties, upon which private email, or a list more focused on
the topic might be where to go. Please do post details here.

Even without knowing more about what you are doing, I would urge you
to use an existing facility for efficient geospatial search, rather
than reinventing the wheel. The ones that I know about are:
  * Lucene now has geospatial search, and Solr/Elasticsearch build on
top of that
  * postgis offers geospatial search on top of the PostgreSQL database.
There are more options depending on your use case.

Would strongly recommend using migrations, rather than changing the

Have not yet had occasion to use Django 1.7's migrations, but South

You should take a look at https://docs.python.org/3/whatsnew/2.7.html , and as

pygtk has pretty decent documentation, which you might want to read carefully:
Please see the right-hand sidebar at http://www.pygtk.org/

From the tutorial: The variables and functions that are defined in the PyGTK

even when they are named as gtk.XXX. If you are so inclined, you can look into
the two modules to figure out what is defined where.

Normally, with a framework like Django. one designs the system

yes, that is the way

An exception is if one already has a database with tables, say from

 Hello,

 I tried to make a log file in a python script. After adding the line below


 logging.basicConfig(filename='LOG_FILE.log',
 filemode='w',
 format='%(asctime)s %(message)s',
 level=logging.DEBUG)

 Now when I try to run a binary file using os.system or commands.getoutput, 
 script simply hangs. Binary file is supposed to provide me the number of 
 items available within two numbers in a particular branch

 Usage of that command : range branch Begin_number End_number

 Without using the above logging line, I could run this command.

 I used trace python -m trace --trace myscript.sh to see where exactly it 
 hangs.Last few lines from the output of trace work of python is

 commands.py(58): import os
 commands.py(59): pipe = os.popen('{ ' + cmd + '; } 21', 'r')
 commands.py(60): text = pipe.read()

I see no reason from the above that a logging statement like the above
would cause the script to hang. Please show us your complete script.
If it is tool long, use pastebin.com, and post the link here.

need authenticated services, though that is not very different from passing
lgn itself.

What is your objection to passing the login class instance? Alternatively,
all services needing authentication could be part of a single class, where
login() is a class method or derived from a base class.

 Would love to more about it.

Passing multiple arguments to the function seems to be the
cleanest approach, as it separates out variables in the class from
those in a specific usage of it. Not only is this pretty standard in
Python, reworking the class every time for a new script makes no
sense to me. Whether the multiple arguments are passed as such,
or as keyword arguments is a matter of design, and a bit of preference.

 Hi,

 I need to post messages on a JMS queue on a remote server.
 RabbitMQ is compliant to JMS v1.1 and I can use it, however I am not able
 to find any specific reference documentation for developing a JMS Producer
 using RabbitMQ.

 The one's available use AMQP Producer and Consumer.

 Any pointers would be helpful.

Why exactly are you asking on a Python list?

Sorry, did not mean to humiliate you, and I do not understand

I still disagree with your contention that since JMS clients can
be written in Python, it is germane for the list. By that argument,
almost anything would be permitted here. Nor do I buy the
argument that delete was just a click away: So, are you OK

Am going to stop following up on this thread, but IMHO there is

I would not do that at all. There are subtle differences between HTML
and XML, e.g., HTML allows tags that are not explicitly closed with
/tag. Try a sub-element with the img or input tag. In general,
valid HTML is not necessarily valid XML, and vice versa. The bugs

This description is not very clear, at least to me. What is an

in this case? Why does it make sense to use a random search?

 In each iteration of the algorithm I generate a combination of a subset of
 nodes chosen randomly from the whole node-set, as a list. In the same loop I
 carry out a modification of the generated list and calculate the objective
 value associated with this . A particular generated list in any loop will
 give rise to a single modified list.

 Now I do not want same list to be generated again and again, so I maintain a
 super-list of generated lists and check the membership of each new list in
 this super-list. I restart the loop if same list appears again in the
 algorithm. As I already said the original list gets modified within an
 iteration. The problem is that although I append the super-list with the
 original list before modification, as soon as I modify this original list
 the list added to the super-list also changes automatically. Thus the
 iteration goes on even if the same list is generated again and again.

Maybe you would care to explain how this fits with the list's stated
purpose of This group is for discussions related to the Python

Python.?

IMHO, this is a technically-oriented list, not a socially-oriented one.

The ?btn=view_pagesel=Profile is not part of the

This is better suited to a Redhat forum, or RHEL support
if you purchased that. It is also a very basic question about
maintaining system packages, and you would do well to learn
such things on your own.

Been a while since I used RPM-based systems, but
  yum install python
should do the trick. You will need to have set up
network access on your VM.

This is a little off-topic, but nevertheless:

  be a big plus in our book when it comes to a hiring decision.
* You should decide on a more specific area that you want to

* If your experience in that area is not very extensive, consider
  finding a company/organisation that works in the area, and

  is to find an open-source project in that area of work, and

 Basically one line solution .

Do you mean list comprehension? Even so, it is not clear how
the resulting list is to be derived from the original. Rather than
showing us solutions that already assume a particular way, could
you describe the problem in words?

Else, the most efficient way to achieve your expected result would be
  [[a[1], a[3]], [a[2]] + a[3:]]

 Bangpypers,

 Having a little trouble in parsing a file of 702 line appox,

 the file is in the format

 [Space]

If the above format is strictly followed, this should do it,
assuming you can read the entire file into a string (s in
the example below.

import re
TITLE_RE = re.compile( r'#\n#([^\n]*)\n#\n \n\[([^\]]*)\]\n \n',
re.MULTILINE|re.DOTALL )
for m in TITLE_RE.finditer( s.strip ):
 title, info = m.groups()
 print title, info

Error handling, and reading chunks from a large file
are left as an exercise for the reader.

Also, if the file format is at all more complex, and
maybe even in this case, I would write a parser
rather than use regular expressions.

 Hi,

 I am using python 2.6.

 I need a way to make following code working without any ValueError .
  a, b, c, d = (1,2,3,4)
  a, b, c, d = (1,2,3).

 Note: Number of values in the tuple will change dynamically.


Is the maximum length of the tuple fixed?
If so, you can pad the tuple with blank variables to
this maximum length, viz.,
NMAX = 4
UNKNOWN_VAL = ''
t = (1, 2, 3)
a, b, c, d = t + (NMAX - len(t)) * (UNKNOWN_VAL,)

If the maximum length is not fixed, you should probably
revisit your design.

 I don't think we should be so religious about using Python. After all
 programming languages are tools to get job done.

Er, I am not. But, there could well be a good reason for someone
to want to do that in Python. Since they are asking on a Python
group, a reasonable assumption is that they have done their
homework and want a Python solution.

 Remember that Diaspora was developed by a bunch of very smart chaps
 over couple of years and it was able to raise $200K of funds on
 kickstarter. It would take equal amount of efforts (or even more) and
 resources to start building something from scratch again.

 Rejecting an already available opensource project, even before
 considering its merits, just because it is not written in your
 favorite programming language is not a good idea.

Have not looked at Diaspora, and it could well be quite good. RoR
is also perfectly fine for a RAD framework. I am not sure how it
came across that I was rejecting Diaspora out of hand?

Re: [BangPypers] Configuring web2py to run on apache with Centos5.8

[Gora Mohanty]

Hi,

While I am far from being an expert in setting up Apache,
there seem to be several things wrong with your Apache
config.
1. Your ServerName is wrong unless you have aliased it
locally, or are hosting on example.com :-)
2. Your WSGIScriptAlias is at /wpy , but in some cases
you are accessing /
3. The Order parameter for Directory /root/web2py/web2py
should be Order Deny,Allow so as to match the rest of
the steps:
http://httpd.apache.org/docs/2.0/mod/mod_access.html#order

4. This is off-topic for the list :-)
