I share files in a folder to other devices by invoking a server using python -m SimpleHTTPServer.
I just tried to stream videos/audio (standard mp4 & mp3, both under 20MB) to another computer using this & it WORKS (but by throwing the errors (listed down) in the terminal).
Somehow, the video/audio fails (except very small mp3 files) to play with Safari in iPhone/iPad. It is definitely not related to the media files, as I streamed them successfully using Apache in iPhone.
Any idea why it happens?

As sugested either use python alternatives, What is a faster alternative to Python's http.server (or SimpleHTTPServer)? or use full blown web serwer altogether. Quick google suggests that Mac supports both Nignx and Apache2.

I have a simple application that I'd like to deploy to a GAE standard or flexible environment, and it requires the generation of simple audio files.
I have code that runs well locally (on the dev server) using PySoundfile, but I run into errors with the underlying libsndfile when the application is deployed.

I've also tried wave unsuccessfully.
In the flexible environment you could try to build and use a custom runtime in which you can add non-python dependencies, like OS libraries (libsndfile in your case and whatever else you may need).
Basically the same answer as in How oracle jdk can be configured in Google App Engine Flexible environment.
I am using django-storages which I have used in the past to work with AWS S3. But with Microsoft Azure I am running into errors which return no results on google.
I am developing using python 3 and Django 1.8.4. I am using django-storages and django-storages-redux for python 3 support.
When calling ./manage.py collectstatic and enter yes I get two (!) errors:

I followed the meager instructions for using django-storages with azure here.
Any Idea what might be causing this error? Has anyone succesfully deployed a django 1.8 app with azure as a storage and static files backend?
edit: I have hacked around a bit in the django-storages module:
Using
import azure.storage.blob
self._connection = azure.storage.blob.blobservice.BlobService(
instead of just
self._connection = azure.storage.BlobService(
But now I am getting different errors which makes me believe that this problem actually runs deeper.
I have found the issue:
django-storages-redux is simply outdated and not compatible with the newest version of the azure sdk
a pull request by the author is in the works:
https://github.com/jschneier/django-storages/pull/86
I did my own quickfix here:
https://github.com/schumannd/django-storages
Since you are using a storage platform on top of our storage library, our support may be limited. It looks like there was a change to restructure and rename parts of the python client lib and the “Azure-Storage” platform you’re using hasn’t updated their tooling. Others have had similar issues using this platform as well. Please see the following issue filed against Django-storages:
https://bitbucket.org/david/django-storages/issues/225/azure-storages-are-incorrectly-imported
Reviewing the “backend” file for your Django solution it looks like this offers you very little convenience over using our storage service directly. You may want to consider using our library since it will give you the most flexibility with data storage. If you prefer to use Django-storages, you could contact them and see if they will fix it or fork their codebase and make the fix yourself. You can see all the work we are doing to improve this library here:

EOFError: [Errno 10054] An existing connection was forcibly closed by the remote host
The stack trace does not refer to a line in my code, which is too long to reproduce here. However, the key component other than the standard python library is Ghost.py.
Thanks!
This means the server closed the connection unexpectedly, usually because it crashed for some reason. In this case, it looks like the client is pyscripter and the server is a subprocess running your app, and it sounds like the subprocess crashed so hard that it did not gracefully close the connection or send back a meaningful traceback. So, either there is a bug in pyscripter or a bug in your code. My advice is to run your app without the IDE and see if you can reproduce the issue and get a meaningful traceback.
I came across a page on Hacking the Kinect. It was discussing how to interface with the system. The code I used is as follows.
The script comes from Lady ada in her post on hacking the connect.

usb.core.USBError: [Errno 16] Resource busy
The main problem here is that libusb is returning an error code, "Resource busy". This could be a permissions problem. Try running your program with sudo and see if that fixes it. This link looks promising, because it talks about how to set up a udev rule so you don't have to run as root:
pyusb: cannot set configuration
If that does not help, you could Google around for "libusb resource busy".
