How to make Jupyter Notebook full screen

Problem:

The Jupyter Notebook has 900 pixels in width and don't use all the "potential" of your screen.

Especialy when you try to make a presentation of the big screen and you have to Zoom It. (CTRL + MOUSE_SCROLL-UP)

That is exactly where you need the "Full Potential" of you screen.

You play with styles in the Browser's Developer Tool, but this effort is not reusable.

Solution:
Use the Stylebot Extention for Chrome

This extension will save your css and apply it to site when you visit it.

Steps to use
1. Install it
2. Navigate Jupyter Notebook page
3. Open the Stylebot

4. At the bottom of the panel click "Edit CSS"

5. Copy Paste this:
#notebook-container {
    padding: 0px;
}
.prompt {
    min-width: 10ex;
}
div.container {
    width: 95%;
}

so it should look like this:

If you have trouble on "pasting" - just retype this css ;-)


DONE! now it looks way batter - enjoy your presentation!

FYI - the Jupyter Notebook page handles most of the keyboard shortcuts so it's could be tricky to work with Stylebot on JN page.
I recommend to adjust your styles in the Developer Tools and the copy&paste the result into Stylebot.

Sampling Distribution

Sampling distribution

Imagine you have some data and you and you would like to know it's properties, like - mean, or average or something else - a Point Estimate. But you don't have a way to work with full data set (it's to large, or it's not fully available to you). But you have access to some portion of it.

To have an good aproximate value of that data you can make the Sampling Distribution.

The sampling distribution represents the distribution of the point estimates based on samples of a fixed size from a certain population.

 It is useful to think of a particular point estimate as being drawn from such a distribution.

To make that point more visible I made the set of tests to show that it really works - the sample size is our variable that experiment.

import mysql.connector
import pandas as pd
import numpy as np
from scipy.stats import bernoulli, binom, poisson, norm, uniform, beta
import matplotlib.pyplot as plt

Distributions and how to plot them with SciPy

Intro

To make the plotting is simple (not that painful), in that post I will make few plots with different distributions.

First importing the libraries. I will use the matplotlib for plotting the data. SciPy one of the core libraries for data science calculations:

import numpy as np # we will use it for generation the arrays
from scipy.stats import bernoulli, binom, poisson, norm, uniform, beta
import matplotlib.pyplot as plt

To make printing comfortable a made the printing function for Mean, Variance, Skew, Kurt:

def print_mvsk(*args):
    t = args[0]
    mean, var, skew, kurt, = float(t[0]),float(t[1]),float(t[2]),float(t[3])
    sd = np.sqrt(var)
    print(f'mean:{mean:.4f}\tvar:{var:.4f}\tskew:{skew:.4f}\nsd:{sd:.4f}\tkurt:{kurt:.4f}')

Performing Accurate Decimal Operations

In python the decimal calculations using the IEEE 754 algorithm.
>>> a = 4.1
>>> b = 2.2
>>> a + b
6.300000000000001

that means that
>>> (a + b) == 6.3 
False
Because python's float type stores data using the native representations.

If you want more accuracy Decimal class from decimal module can help you with that.

>>> from decimal import Decimal
>>> a = Decimal('4.1')
>>> b = Decimal('2.2')
>>> a + b
Decimal('6.3')
>>> (a + b) == Decimal('6.3')
True

Skype Admin

To get list of devices where you skype in used now just 
- open chat with anyone from your contact list
- type /showplaces and hit Enter

that command will show the list of "places" where you are signed it.

Рубка Дров

Увлекательный процесс я вам скажу, просто рубишь и складываешь. Придумываешь как бы это сделать быстро, эффективно и в соответсвии с ожиданием конечного потребителя - печки.

Чтобы и размер подошел и были щепки на растопку и чтобы не сильно мелко и т.п.

Но как показывается практика:

Раз - пила, два – топор: дров и щепок полон двор

и такие вещи как опилки и мелкие дровишки появляются в любом случай, как ты не целься.

Delete files or folders

NEVER RUN

rm -fr /*

Я сделал это на Prod сервере и это оказалась классическая "шутка". >_<

Суть "шутки" в том что когда вы выполняете
dir \.
в WIndows - то \. обозначает текущую директорию

а в Linux  /. обозначает root т.е. корневую директорию.

соотв ожидаемые результат противоположен!
Wellcome to linux world.
 На самом деле, DIR \. дает листик ресурсво с начало каталога. век живи век учись

You can Run

rm -r cache/

-- 

pwd - текущая директория

ls -alh

Create link

ln -sfn 2016-02-17-13-20 html

-s make symbolic links instead of hard links
