    *pyensae* does not declare all dependencies
    by default.

    :categories: code
    :rawfile: 2018/2018-05-05_api.rst

    API started to be difficult to maintain and
    unit test. The code was moved to
    :epkg:`manydataapi` (linkedin, velib).

    :rawfile: 2018/2018-03-22_cctx.rst

    I came accross this package:
    `cctx <https://github.com/ccxt/ccxt>`_.
    The summary is the following:
    *A JavaScript / Python / PHP cryptocurrency trading library with support for 90+ exchanges*.
    The library is available in javascript, php, python but
    the last two languages are obtained by translating the
    javascript into python and php.
    There are a few commits per day.
    That's moght be worth following if you
    are interested cryptocurrencies.

    :keywords: pyenbc,StockPrices,data
    :categories: finance
    :rawfile: 2018/2018-03-16_google_finance.rst

    After :epkg:`Yahoo Finance <https://finance.yahoo.com/>`_
    made it more difficult to access historical data,
    `Google Finance <https://finance.google.com/finance/historical>`_
    stopped giving historical data. So you should see the
    following error message:

    :title: Yahoo finance needs cookie (2)

    :keywords: module,pyenbc
    :categories: module
    :rawfile: 2017/2017-12-17_yahoo_finance.rst

    I wrote about :epkg:`Yahoo Finance <https://finance.yahoo.com/>`_
    was difficult to automate:
    :ref:`Yahoo finance needs cookie <blog-yahoo-finance-201711>`.
    A module handles was implemented to go around that obstacle:
    `yahoo-historical <https://github.com/AndrewRPorter/yahoo-historical>`_.
    Just added it to :class:`StockPrices <pyensae.finance.astock.StockPrices>`
    when specifying ``url='yahoo_new'``.

    :keywords: module,pyenbc
    :categories: module
    :rawfile: 2017/2017-11-28_split.rst

    For version 1.2, the module was split and module
    :epkg:`pyenbc` will take functions, classes which
    deal with remote functionalities.

    `Yahoo Finance <https://finance.yahoo.com/quote/BNPQY/history?p=BNPQY>`_
    now requires cookies to download the data and it becomes
    difficult to automate the downloading of historical data.
    I had to change the default provider to
    `Google <https://www.google.com/finance>`_. However, it is not
    possible to get historical prices for European markets.
    For these one,
    `quandl <https://www.quandl.com/data/EURONEXT/BNP-Bnp-Paribas-Act-A-BNP>`_
    seems to be the best alternative as there is a dedicated module
    to get the data
    `quandl <https://www.quandl.com/tools/python>`_. However, historical
    data do not get as far as Google's.
    See :class:`StockPrices <pyensae.finance.astock.StockPrices>`.

    :keywords: folium
    :categories: graphs
    :rawfile: 2016/2016-10-27_folium.rst

    There is no option to change the size of a
    `folium <https://github.com/python-visualization/folium>`_ map embedded in a notebook.
    I updated function
    :func:`folium_html_map <pyensae.notebook_helper.folium_helper.folium_html_map>`
    to do so.

    :rawfile: 2016/2016-07-05_azure_path.rst

    For all the magic commands associated to Azure
    (class :class:`MagicAzure <pyensae.remote.magic_azure.MagicAzure>`),
    the path ``/part1/part2``
    is converted into ``container/part1/part2``. For path ``part1/part2``,
    ``path1`` is the container.

    :keywords: SQL,flat file,import,dataframe
    :categories: SQL
    :rawfile: 2016/2016-06-22_import_flatfile.rst

    This is a simple script to import big files into a sqlite3 database,
    too big to fit in memory. It relies on
    function :func:`import_flatfile_into_database <pyensae.sql.database_helper.import_flatfile_into_database>`.
