exciting ambitious goals, zuckerberg took two weeks to implement the social platform.
So my recommendation is: you should continue to discuss and think about it.
Which of the following is not recommended? which one is faster, which is easier to develop and implement quickly, and the vision must be put into the long run? So, let's have another meeting to discuss it? Select php for quick development and make the pythonphp environment well deployed.

the branching factor.
What is branching factor? Some translateSplit Rate. If branching factor is high, the higher the computing cost. It can also be understood that the higher the split rate, the more possibilities there will be, and the larger the amount to be calculated.
The above example q = 1/N is just an example. Let's look at the following real data:

Another requirement I have for this scientific computing environment is the ability to coexist with multiple Python versions, especially the coexistence of 2.x and 3.x. This can be done by virtualenv. Anaconda is also achieved through it.
The following is a Conda to create a python2 version of the python2.7 environment.

Conda's repo extensions are not too new. if you want to update them, you may need to use PyPI or download the source code yourself. Conda and pip are well correlated. You can use conda to manage things installed using pip, which is better than Canopy. Nltk, jieba, and gensim I installed with pip.
