Three Ways to Create Dockernized LaTeX Environment

Introduction

We can run a Docker application in any environment, Linux, Windows, or Mac. Docker provides a set of official base images for most used operating systems and apps. Docker allows you to take full control of your environment, installing what you need, removing, and installing from Dockerfile.

In this article, I will show you three ways how to use LaTeX on Docker and VSCode Remote Containers extension. In the first part, we use tianon/latex image, and qmcgaw/latexdevcontainer Docker image in the second part. At the end, we create our image based on the qmcgaw/latexdevcontainer Docker image.

Setup

If you wish, you can delete LaTeX from your computer.

For me I needed to run:

$ brew uninstall mactex

Please install Docker Desktop and VSCode’s Remote-Containers and LaTeX-Workshop VSCode extension.

Different Ways NumPy Creating ArThere are three different ways to create Numpy arrays

Different Ways to Create Numpy Arrays

At the heart of a Numpy library is the array object or the ndarray object (n-dimensional array). You will use Numpy arrays to perform logical, statistical, and Fourier transforms. As part of working with Numpy, one of the first things you will do is create Numpy arrays. The main objective of this guide is to inform a data professional, you, about the different tools available to create Numpy arrays.

There are three different ways to create Numpy arrays:

Using Numpy functions
Conversion from other Python structures like lists
Using special library functions
Using Numpy functions
Numpy has built-in functions for creating arrays. We will cover some of them in this guide.

Creating a One-dimensional Array
First, let’s create a one-dimensional array or an array with a rank 1. arange is a widely used function to quickly create an array. Passing a value 20 to the arange function creates an array with values ranging from 0 to 19.

1
2
3
import Numpy as np
array = np.arange(20)
array
python
Output:

1
2
3
4
array([0, 1, 2, 3, 4,
5, 6, 7, 8, 9,
10, 11, 12, 13, 14,
15, 16, 17, 18, 19])
To verify the dimensionality of this array, use the shape property.

1
array.shape
python
Output:

1
(20,)
Since there is no value after the comma, this is a one-dimensional array. To access a value in this array, specify a non-negative index. As in other programming languages, the index starts from zero. So to access the fourth element in the array, use the index 3.

1
array[3]
python
Output:

1
3
Numpy Arrays are mutable, which means that you can change the value of an element in the array after an array has been initialized. Use the print function to view the contents of the array.

1
2
array[3] = 100
print(array)
python
Output:

1
2
3
4
5
[ 0 1 2 100
4 5 6 7
8 9 10 11
12 13 14 15
16 17 18 19]
Unlike Python lists, the contents of a Numpy array are homogenous. So if you try to assign a string value to an element in an array, whose data type is int, you will get an error.

1
array[3] =‘Numpy’
python
Output:

1
ValueError: invalid literal for int() with base 10: ‘Numpy’
Creating a Two-dimensional Array
Let’s talk about creating a two-dimensional array. If you only use the arange function, it will output a one-dimensional array. To make it a two-dimensional array, chain its output with the reshape function.

1
2
array = np.arange(20).reshape(4,5)
array
python
Output:

1
2
3
4
array([[ 0, 1, 2, 3, 4],
[ 5, 6, 7, 8, 9],
[10, 11, 12, 13, 14],
[15, 16, 17, 18, 19]])
First, 20 integers will be created and then it will convert the array into a two-dimensional array with 4 rows and 5 columns. Let’s check the dimensionality of this array.

1
array.shape
python
Output:

1
(4, 5)
Since we get two values, this is a two-dimensional array. To access an element in a two-dimensional array, you need to specify an index for both the row and the column.

1
array[3][4]
python
Output:

1
19
Creating a Three-dimensional Array and Beyond
To create a three-dimensional array, specify 3 parameters to the reshape function.

1
2
array = np.arange(27).reshape(3,3,3)
array
python
Output:

1
2
3
4
5
6
7
8
9
10
11
array([[[ 0, 1, 2],
[ 3, 4, 5],
[ 6, 7, 8]],

   [[ 9, 10, 11],
    [12, 13, 14],
    [15, 16, 17]],

   [[18, 19, 20],
    [21, 22, 23],
    [24, 25, 26]]])

Just a word of caution: The number of elements in the array (27) must be the product of its dimensions (333). To cross-check if it is a three-dimensional array, you can use the shape property.

1
array.shape
python
Output:

1
(3, 3, 3)
Also, using the arange function, you can create an array with a particular sequence between a defined start and end values

1
np.arange(10, 35, 3)
python
Output:

1
array([10, 13, 16, 19, 22, 25, 28, 31, 34])
Using Other Numpy Functions
Other than arange function, you can also use other helpful functions like zerosand ones to quickly create and populate an array.

Use the zeros function to create an array filled with zeros. The parameters to the function represent the number of rows and columns (or its dimensions).

1
np.zeros((2,4))
python
Output:

1
2
array([[0., 0., 0., 0.],
[0., 0., 0., 0.]])
Use the ones function to create an array filled with ones.

1
np.ones((3,4))
python
Output:

1
2
3
array([[1., 1., 1., 1.],
[1., 1., 1., 1.],
[1., 1., 1., 1.]])
The empty function creates an array. Its initial content is random and depends on the state of the memory.

1
np.empty((2,3))
python
Output:

1
2
array([[0.65670626, 0.52097334, 0.99831087],
[0.07280136, 0.4416958 , 0.06185705]])
The full function creates a n * n array filled with the given value.

1
np.full((2,2), 3)
python
Output:

1
2
array([[3, 3],
[3, 3]])
The eye function lets you create a n * n matrix with the diagonal 1s and the others 0.

1
np.eye(3,3)
python
Output:

1
2
3
array([[1., 0., 0.],
[0., 1., 0.],
[0., 0., 1.]])
The function linspace returns evenly spaced numbers over a specified interval. For example, the below function returns four equally spaced numbers between the interval 0 and 10.

1
np.linspace(0, 10, num=4)
python
Output:

1
array([ 0., 3.33333333, 6.66666667, 10.])
Conversion from Python Lists
Other than using Numpy functions, you can also create an array directly from a Python list. Pass a Python list to the array function to create a Numpy array:

1
2
array = np.array([4,5,6])
array
python
Output:

1
array([4, 5, 6])
You can also create a Python list and pass its variable name to create a Numpy array.

1
2
list = [4,5,6]
list
python
Output:

1
[4, 5, 6]
1
2
array = np.array(list)
array
python
Output:

1
array([4, 5, 6])
You can confirm that both the variables, array and list, are a of type Python list and Numpy array respectively.

1
type(list)
python
list

1
type(array)
python
Numpy.ndarray

To create a two-dimensional array, pass a sequence of lists to the array function.

1
2
array = np.array([(1,2,3), (4,5,6)])
array
python
Output:

1
2
array([[1, 2, 3],
[4, 5, 6]])
1
array.shape
python
Output:

1
(2, 3)
Using Special Library Functions
You can also use special library functions to create arrays. For example, to create an array filled with random values between 0 and 1, use random function. This is particularly useful for problems where you need a random state to get started.

1
np.random.random((2,2))
python
Output:

1
2
array([[0.1632794 , 0.34567049],
[0.03463241, 0.70687903]])

Applying the Three Ways of DevOps to Accelerate Your Organization

Introduction

The emergence of DevOps has marked a seismic shift in the software world in recent years. The allure is the opportunity it offers to organizations to increase their levels of productivity by orders of magnitude and outpace their competitors to win in the marketplace.

However, DevOps draws from a wide array of areas of research and represents their convergence into a broad set of philosophies, practices, and tools. With such a vast body of knowledge to consider, it’s hard to know where to begin when attempting to adopt it.

Fortunately, we can look to DevOps thought leaders to point us in the right direction. First introduced in The Phoenix ProjectandThe DevOps Handbook is the concept of _The Three Ways. _Itcaptures the conceptual underpinnings of the entire movement. This model is a powerful tool that identifies the characteristics of DevOps maturity and describes the path that your organization can follow to get there.

We’ll be leveraging The Three Ways in this article by examining some practical actions your organization can take while pursuing DevOps maturity. It can help when the purported benefits of DevOps seem elusive. This feeling burdens organizations that struggle with the underlying principles of DevOps.

We’ll discuss in more detail, within the context of The Three Ways to provide the insight necessary to fight past barriers to adoption. As with any cultural transformation, the adoption of DevOps requires a shift in mindset and values embodied by specific practices and approaches. This guide is a collection of ideas to get started or to strategize about potential next steps. It can be used by any technology professional at any level of your organization to accelerate or even begin its DevOps journey.

The Three Ways

The First Way

The First Way is about accelerating the pace of delivery through your value stream. It can encompass the work of an individual contributor, a team, or even an entire organization. It describes how the business defines value-creating functionality for the development organization. Development builds the software that captures the value and passes it to operations to deliver it as a service to the customer.

The arrow only points from left to right, suggesting that there is never a backward flow. The implication is that known defects never get passed downstream, never negatively impacting the whole system with local optimization, and always pursuing greater throughput by continuously unlocking a greater understanding of the system to improve it.

Figure 1. The First Way flows from left to right.

The Second Way

In The Second Way, your organization will establish a feedback loop that amplifies signals of quality and efficiency and enables the practice of continually making improvements by addressing any uncovered issues. You create a virtuous cycle of refinement, which allows a better understanding of customer needs and faster detection of problems, ideally moving to the predictive phase to prevent the issues from occurring in the first place.

Now you can begin the work of shortening the feedback cycle, which paves the way to add even more sensing mechanisms to detect weaker signals. By “sensing mechanisms,” we mean ways to inform developers or operations of issues occurring in production. “Weaker signals” refers to different characteristics of the running software that provides insight into the quality, stability, or other essential aspects of the system.

_The Second Way _helps your organization be proactive by reacting to predictive indicators of problems and addressing them before problems occur. Most of the detection mechanisms can be automated, which eliminates waste and helps your entire organization move faster without fear of breaking something.

Figure 2. The Second Way is a feedback loop that drives continuous improvement

The Third Way

As your organization leverages the apparatus created in _The First _and _Second Way_s, The Third Way revolves around the idea of enabling rapid experimentation for an even more in-depth understanding of customer needs. Since the apparatus is all-around promoting a fast flow, prevention of issues, and recovery from problems, organizations can take more chances in The Third Way and can conduct bold experiments right in production.

The cultural impacts of these concepts are apparent in several practices. Teams able to begin their journey on The Third Way regularly allocate time for improving daily work. They may also intentionally introduce faults into the system to test their ability to respond and recover to improve the system and their skills. Organizations will also reward bold experimentation for fostering innovation, nurturing learning, and embedding courageous behaviour into their cultural DNA.
