  • From Concept To Live In Two Weeks With Django

    My team had two weeks to make a viable product. We were a random group of people pulled together with a desire to help our local community in Frederick, Maryland. We were a student, a web designer, a former realtor turned IT support person, and a software developer.

    Our mission, which was put forth by the virtual hackathon that brought us together, was to try to make a tool to help the local homeless.

  • How to Convert a numpy Array to Pandas Dataframe: 3 Examples

    In this Pandas tutorial, we are going to learn how to convert a NumPy array to a DataFrame object. Now, you may already know that it is possible to create a dataframe in a range of different ways. For example, it is possible to create a Pandas dataframe from a dictionary.

    As Pandas dataframe objects already are 2-dimensional data structures, it is of course quite easy to create a dataframe from a 2-dimensional array.

  • Digging Into Dagster: An Opinionated Open Source Framework For Data Orchestration

    Data applications are complex and continually evolving, often requiring collaboration across multiple teams. In order to keep everyone on the same page a high level abstraction is needed to facilitate a cross-cutting view of the data orchestration across integration, transformation, analytics, and machine learning. Dagster is an innovative new framework that leans on the power and flexibility of Python to provide an extensible interface to the complete lifecycle of data projects. In this episode Nick Schrock explains how he designed the Dagster project to allow for integration with the entire data ecosystem while providing an opinionated structure for connecting the different stages of computation. He also discusses how he is working to grow an open ecosystem around the Dagster project, and his thoughts on building a sustainable business on top of it without compromising the integrity of the community. This was a great conversation about playing the long game when building a business while providing a valuable utility to a complex problem domain.

  • Exploring HTTPS and Cryptography in Python

    Have you ever wondered why it’s okay for you to send your credit card information over the Internet? You may have noticed the https:// on URLs in your browser, but what is it, and how does it keep your information safe? Or perhaps you want to create a Python HTTPS application, but you’re not exactly sure what that means.

    In this course, you’ll get a working knowledge of the various factors that combine to keep communications over the Internet safe. You’ll see concrete examples of how a Python HTTPS application keeps information secure.

  • py3status v3.29

    Almost 5 months after the latest release (thank you COVID) I’m pleased and relieved to have finally packaged and pushed py3status v3.29 to PyPi and Gentoo portage!

    This release comes with a lot of interesting contributions from quite a bunch of first-time contributors so I thought that I’d thank them first for a change!

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
