• Financial Charts / Graphs in Ruby or Python

  - by Eric the Red

  What are my best options for creating a financial open-high-low-close (OHLC) chart in a high level language like Ruby or Python? While there seem to be a lot of options for graphing, I haven't seen any gems or eggs with this kind of chart. http://en.wikipedia.org/wiki/Open-high-low-close_chart (but I don't need the moving average or Bollinger bands) JFreeChart can do this in Java, but I'd like to make my codebase as small and simple as possible. Thanks!

  - by Bijan

  Ignoring all the characteristics of each languages and focusing SOLELY on speed, which language is better performance-wise? You'd think this would be a rather simple question to answer, but I haven't found a decent one. I'm aware that some types of operations may be faster with python, and vice-versa, but I cannot find any detailed information on this. Can anyone shed some light on the performance differences?

• Installing Python egg dependencies without apt-get

  - by l0b0

  I've got a Python module which is distributed on PyPI, and therefore installable using easy_install. It depends on lxml, which in turn depends on libxslt1-dev. I'm unable to install libxslt1-dev with easy_install, so it doesn't work to put it in install_requires. Is there any way I can get setuptools to install it instead of resorting to apt-get?

• Code Analysis In Python

  - by Jerub

  What tools are good to use for code analysis in python? I have a large source repository split across multiple projects, and I would like to be able to run tools across the directories to see details like Cyclomatic Complexity, and perhaps be able to spot errors using static analysis. Ideally, I would like to be able to produce a report about the health of the source code, so we can spot problem areas that need to be addressed.

• Dealing with wacky encodings in Python

  - by Tyson

  I have a Python script that pulls in data from many sources (databases, files, etc.). Supposedly, all the strings are unicode, but what I end up getting is any variation on the following theme (as returned by repr()): u'D\\xc3\\xa9cor' u'D\xc3\xa9cor' 'D\\xc3\\xa9cor' 'D\xc3\xa9cor' Is there a reliable way to take any four of the above strings and return the proper unicode string? u'D\xe9cor' # --> Décor The only way I can think of right now uses eval(), replace(), and a deep, burning shame that will never wash away.
