Introduction

As an application enters production, the most challenging portion begins, and the maintenance starts. The maintenance team debugs applications whenever they are required to do so. The debugging team looks for solutions that will solve the problem ASAP without interfering with production.

Debugging an application is difficult owing to poor documentation. However, debugging assists us in mitigating risks, making it cost-effective for the organization. In this article, we will discuss the best approaches to debugging applications in production.

1. Document External Dependencies Extensively

Documentation is often a big assistance when it comes to debugging. It provides the first step in any debugging process. …

I have covered quite a number articles related to NLP toolkit of various Asian languages in the past:

• Khmer Natural Language Processing in Python
• Beginner’s Guide to PyThaiNLP
• Korean Natural Language Processing in Python
• SudachiPy: A Japanese Morphological Analyzer in Python

Today, let’s explore a little further on Vietnamese instead. By reading this piece, you will learn to perform linguistic analysis on Vietnamese text via an open-source Python package called pyvi.

At the time of this writing, pyvi offers the following functionalities:

• Tokenization
• POS tagging
• Accent marks removal
• Accent marks adding

Handling spreadsheet data in JavaScript

The topic for today is about exceljs, a JavaScript package that acts as Excel workbook manager. Based on the official documentation, exceljs is a package that

… read, manipulate and write spreadsheet data and styles to XLSX and JSON.

Reverse engineered from Excel spreadsheet files as a project.

It is an extremely useful package which provides the following features:

• Creating workbook
• Creating worksheet
• Handling headers and footers
• Setting frozen or split views
• Setting auto filters
• Data manipulation on rows and columns
• Adding data validation
• Adding styles
• Inserting images to workbook

In addition, exceljs is frequently…

By reading this article, you will learn to implement generic sort and filter functions for your dynamically created table in plain JavaScript. At the end of the tutorial, you should be able to achieve the following result:

The topic for today is how repository and directory trees work in Git. For developers already familiar with Git, I am sure that after you make changes to your project, the typical workflow is as follows:

• run git add to stage your changes
• run git commit to add staged changes to the local repository
• run git push to push local repository changes to remote hosting site (GitHub, Gitlab, etc.)

Most of the time, the root directory is the location where your git directory is located. …

In this piece, you will learn about the major differences between GraphQL and REST for fetching data. Code snippets will be provided as a side-by-side reference for both approaches.

For your information, REST refers to representational state transfer architecture in API, and it adheres to the following design principles:

• uniform interface — all requests for the same resources belong to one Uniform Resource Identifier (URI).
• client-server decoupling — client and server are independent of each other and connected via an HTTP endpoint.
• statelessness — each request must contain the relevant information required for processing.
• cacheability — resources should be cacheable…

This is an introductory tutorial on how to conduct data analysis and visualization using a famous data analysis library called Pandas. Here is a quick summary of what will be covered in this tutorial:

• installation of Python packages (requests, pandas, jupyter)
• weather data collection (using the Tomorrow.io weather API)
• data analysis (mean, min, max, std, etc.)
• data visualization (bar plot, pie chart)

Let’s proceed to the next section and start installing the necessary packages.

Setup

It is highly recommended to create a virtual environment before you continue. Activate it and run the following commands to install all the required dependencies:

Requests (optional)

Previously, I have covered a beginner’s guide to Locust in Introduction to Locust: An Open Source Load Testing Tool in Python. In this article, let’s explore a little more with four useful advanced features that are available in Locust:

• Execute tasks sequentially
• Generate custom load shapes (time-based stages)
• Use other custom clients
• Run tasks in parallel

In fact, all of the features mentioned above are not new and have been around in the Locust package for quite some time. Learning these features helps to improve your load testing and make your life easier.
