  • Python Programming

    Python is a powerful multipurpose programming language created by Guido van Rossum.

    It has a simple and easy-to-use syntax, making it a popular first-choice programming language for beginners.

    This is a comprehensive guide that explores the reasons you should consider learning Python and the ways you can get started with Python.

  • Null in Python: Understanding Python's NoneType Object

    If you have experience with other programming languages, like C or Java, then you’ve probably heard of the concept of null. Many languages use this to represent a pointer that doesn’t point to anything, to denote when a variable is empty, or to mark default parameters that you haven’t yet supplied. null is often defined to be 0 in those languages, but null in Python is different.

    Python uses the keyword None to define null objects and variables. While None does serve some of the same purposes as null in other languages, it’s another beast entirely. As the null in Python, None is not defined to be 0 or any other value. In Python, None is an object and a first-class citizen!

  • Test and Code: 101: Application Security - Anthony Shaw

    Anthony Shaw is doing something about it by creating an editor plugin that actually helps you write more secure application code while you are coding.

    On today's Test & Code, Anthony and I discuss his security plugin, but also application security in general, as well as other security components you need to consider.

    Security is something every team needs to think about, whether you are a single person team, a small startup, or a large corporation.

    Anthony and I also discuss where to start if it's just a few of you, or even just one of you.

  • Universal app reload with entr

    A useful feature many web frameworks have is auto-reload. Your app is running in the background, you change the code, and the app is restarted with those changes, so you can try them out immediately. What if you wanted that behavior for everything that you’re writing? And without any coding to implement it over and over in every little project?

    Then you can use entr. It’s a nice little UNIXy [1] tool. It really just does one thing - running commands when files change. And it has a simple, usable interface. You just pass it the names of the files it needs to watch, and give it the command to run.

  • Which verison of Python are you running?

    I actually want to ask you which version of Python3 are you running? Yes, it is a question I have to ask myself based on projects I am working on. I am sure there are many more people in the world who are also in the similar situation.

  • Ubuntu 20.04 LTS Moves Ahead With Python 2 Removal - But Sticks Around For Derivatives

    With Python 2 having been end-of-life since the start of the year and Ubuntu 20.04 being a long-term support release, Ubuntu developers are working hard to ensure Python 2 isn't shipped as part of this next Ubuntu LTS release.

    Indeed, the long process of working to remove Python 2 from Ubuntu 20.04 LTS is panning out at least as far as the official ISO is concerned. Among recent action has included removing the python* binary packages (the generic package names not python2-* or python3-*) and addressing packages that depended upon the unversioned python package names, scanning for any lingering Python 2 dependent binary packages, working to add a python-is-python2-but-deprecated package that will symlink /usr/bin/python to python2 for any hold-outs, and related work.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
