  • Introduction to Building Custom Apache Airflow Operators

    If you work in data engineering, then the chance are high that you are using or have used Apache Airflow.

    This orchestration tool has become a firm favourite of many organisations. It was chosen by Google when they were looking at an orchestration tool to include in their cloud offering Google Cloud Composer.

    Airflow comes with a ton of operators out of the box and even more community supplied ones. However, chances are that at some point you might think "it would be really great if I could have my own operator to do X".

    This post is to help give you a starting point for building you own custom Airflow operators in a structured and scalable way via Airflow plugins.

  • Using Python to Check for File Changes in Excel

    Data exchange in healthcare is ... harder than it needs to be. Not all partners in the healthcare arena understand and use technology to its fullest benefit.

    Take for example several health plans which want data reported to them for CMS (Centers for Medicare and Medicaid Services) regulations. They will ask their 'delegated' groups to fill out an excel file. As in, they expect you will actually fill out an excel file, either by manually entering the data OR by potentially copying and pasting your data into their excel file.

    They will also, quite frequently, change their mind on what they want AND the order in which they want the data to appear in their excel file. But there's no change log to tell you what (if anything has changed). All that you will get is an email which states, "Here's the new template to be used for report XYZ" ... even if this 'new' report is the same as the last one that was sent.

  • Algo Trading 101: Building Your First Stock Trading Bot in Python

    It can be overwhelming for a new Python developer to get started with algorithmic trading. I would know because I have been there too! When I began my algo trading journey back in 2017, I had the oppurtunity to fly out to NYC and attend QuantCon, a convention run by one of the largest algo trading funds on the planet: Quantopian. I went to a dozen talks by some of the best quants (short for quantitatives, aka the people doing math and writing strategies for algo funds.) This journey taught me a lot but also left me with a lot of questions: How do I write a bot that can trade stocks? What strategies can I use to be profitable? Trading stocks with an algorithm is no walk in the park. So in this article let's break down the core components of how you build an algo trader.

  • Git turns 15, and becomes even more important for distributed development

    "Every company is a software company!" is the new platitude as companies seek to transform themselves. But buried in that statement is an equally true, and much more interesting observation: Every company is also increasingly dependent on and driven by Git, the distributed version control system developed by Linux creator Linus Torvalds 15 years ago.

    Git wasn't the first version control system for software, but it's had a profound impact on how all organizations build and, increasingly, operate software. To better understand why and how Git has changed the way all organizations build software, I talked with Brendan O'Leary, senior developer evangelist at GitLab.

  • Git Becomes 15: Q&A with GitHub and GitLab

    On April 7, 2005, exactly 15 years ago, Git reached a sufficient maturity state to be self-hosting, meaning Git itself could be used to commit a part of its code. Today, Git has become one of the most widely adopted development tools and has changed the way developers manage their code. InfoQ has taken the chance to talk about Git's significance with GitHub's distinguished software engineer Jeff King and GitLab's senior developer evangelist Brendan O'Leary.

  • 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.
