  • The (non-)return of the Python print statement

    In what may have seemed like an April Fool's Day joke to some, Python creator Guido van Rossum recently floated the idea of bringing back the print statement—several months after Python 2, which had such a statement, reached its end of life. In fact, Van Rossum acknowledged that readers of his message to the python-ideas mailing list might be checking the date: "No, it's not April 1st." He was serious about the idea—at least if others were interested in having the feature—but he withdrew it fairly quickly when it became clear that there were few takers. The main reason he brought it up is interesting, though: the new parser for CPython makes it easy to bring back print from Python 2 (and before).

  • Python Anywhere: Outage report 7 July 2020

    We had an unplanned outage the day before yesterday; it was our first big one since July 2017. It was caused by an extremely unlikely storage system failure, but despite that it should not have led to such a lengthy downtime, and should not have affected so many people. We have some plans on what our next steps should be, and will be implementing at least some of them over the coming months.

  • Enrolling Students - Building SaaS #64

    In this episode, we worked on a view to enroll students into a grade level for the school year. I added all the context data and used Tailwind to design the form layout to pick from a list of available grade levels. We added a variety of unit tests to prove the correctness.

    The enrollment page needed three pieces of data in the context to complete the form. We added the student, school_year, and grade_levels data to the context and wrote tests to show the data in there. We also protected that data from any erroneous access by another user.

    When the data was set, we worked on the template for the form. I set the header to make the enrollment action clear and created the radio input selectors to show the different grade level options. We cleaned up the design and user experience by including some Tailwind CSS classes which made the radio inputs much easier to select.

    At the end of the stream, we wrote the happy path test for the POST request to prove that the enrollment record exists after submission.

  • 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.
