This will only install PHP. If you wish to serve a PHP file to the web you will also need to install a web-server such as Apache, Nginx, or use PHP's built in web-server (php version 5.4+). If you are in a Ubuntu version below 16.04 and want to use PHP 7 anyway, you can add Ondrej's PPA repo...

You first need to run a Stanford CoreNLP server: java -mx4g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -timeout 50000 Here is a code snippet showing how to pass data to the Stanford CoreNLP server, using the pycorenlp Python package. from pycorenlp import Stanf...

In Ruby, a string is just a sequence of bytes along with the name of an encoding (such as UTF-8, US-ASCII, ASCII-8BIT) that specifies how you might interpret those bytes as characters. Ruby strings can be used to hold text (basically a sequence of characters), in which case the UTF-8 encoding is us...

To coerce a variable to a date use the as.Date() function. > x <- as.Date("2016-8-23") > x [1] "2016-08-23" > class(x) [1] "Date" The as.Date() function allows you to provide a format argument. The default is %Y-%m-%d, which is Year-month-day. > ...

Sometimes we want to prepare a context for each test to be run under. The setUp method is run prior to each test in the class. tearDown is run at the end of every test. These methods are optional. Remember that TestCases are often used in cooperative multiple inheritance so you should be careful to...

Pandas uses provides multiple ways to make graphs of the data inside the data frame. It uses matplotlib for that purpose. The basic graphs have their wrappers for both DataFrame and Series objects: Line Plot df = pd.DataFrame({'x': [10, 8, 10, 7, 7, 10, 9, 9], 'y': [6, 4, 5, 5...

Given the following DataFrame: In [11]: df = pd.DataFrame(np.random.randn(6, 3), columns=['A', 'B', 'C']) In [12]: df.set_index(['A', 'B'], inplace=True) In [13]: df Out[13]: C A B 0.902764 -0.259656 -1.864541 -0.695893 0.308893 0...
