  • Python Range Tutorial: Learn to Use This Helpful Built-In Function

    Looping is an integral part of any programming language. In Python, an important component of loops is the built-in range function.

    In this detailed guide, we will walk you through the workings of the range function using examples, and discuss its limitations and their workarounds. Although range is useful for a broad variety of Python programming tasks, this guide will conclude with a couple of data science use cases for the range function.

    For the purposes of this tutorial, we do assume you have at least some knowledge of Python syntax. If you’ve never worked with Python before, we’d recommend starting with this interactive Python fundamentals course first.

  • Deploying WhiteNoise - Building SaaS #35

    In this episode, we updated Continuous Integration, Nginx, and the Ansible deployment tasks to use WhiteNoise. With all the changes in place, we tested things out to verify that WhiteNoise served up the CSS, JS, and image files.

    We started with Circle CI. First, I fixed the JS assets cache because the cache key never changed and Circle did not save fresh assets each build.

    After completing the assets cache, I created a new cache that stored all the static files after running collectstatic. This new cache was necessary for the package step.

  • Qt 5.14 Beta 2 Released As Another Chance To Test The Big Toolkit Update

    The second beta of the forthcoming Qt 5.14 is now available for testing ahead of this Qt5 tool-kit update before more attention turns to focusing on Qt 6.0 for release around this time next year.

    Qt 5.14 went into beta earlier this month while now a second beta is ready with the latest fixes and improvements for new functionality. Qt 5.14 Beta 2 is running just a few days behind schedule while the release cycle is currently about one month behind schedule due to a belated alpha release. Qt Company developers hope to be able to ship Qt 5.14.0 around the end of November but due to a few weeks behind schedule, it's not clear at this point if they will be able to realize that goal.

  • Django Weblog: 2020 DSF Board Nominations

    It is that time of year again to think about next year’s Django Software Foundation’s Board of Directors!

    As you know, the Board guides the direction of the marketing, governance and outreach activities of the Django community. We provide funding, resources, and guidance to Django events on a global level. Further we provide support to the Django community with an established Code of Conduct and make decisions and enforcement recommendations for violations. We work closely with our corporate and individual members to raise funds to help support our great community.

    In order for our community to continue to grow and advance the Django Web framework, we need your help. The Board of Directors consists of volunteers who are elected to one year terms. This is an excellent opportunity to help advance Django. We can’t do it without volunteers, such as yourself. For the most part, the time commitment is a few hours per month. There has been some confusion on this in the past, but anyone including current Board members, DSF Members, or the public at large can apply to the Board. It is open to all.

  • Chris Angelico: 2019 Q2 Community Service Award Winner

    Chris had a very noble reason to start programming: his older brother was doing it so he had to follow suit! This, along with getting into the family business of importing and exporting educational materials, led to a lifelong love of learning and technology. By the 1990’s Chris was working as a developer and first used Python when he needed to embed a scripting language in a C++ project. “Python offered a simple, clean, boilerplate-free scripting language that still had all the power that I needed for that initial project,” he says. Though the project ended up going in a different direction, Chris was already hanging out on Python mailing lists and was there to stay.

    Since 2012, Chris has been an active contributor to the python-dev and python-ideas mailing lists, which are a large part of how the Python language gets developed. python-dev is used by core developers to discuss release dates and plans that could involve breaking changes to Python. On python-ideas, topics surround proposals that haven't matured enough to discuss on python-dev, and contributors can either reject ideas or help to refine them until they can be seriously proposed. “Both lists have a lot of incredibly smart people, but also very opinionated people, so it's pretty awesome to hang out and discuss,” says Chris. “They are significant parts of the funnel that brings proposals to fruition. Many changes start out with a discussion on python-ideas, then perhaps a PEP [Python Enhancement Proposal] is written, and it's discussed at length before migrating to python-dev for detailed discussion, and then finally code gets written and merged in.”

  • 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.
