  • Mike Driscoll: PyDev of the Week: Bob Belderbos

    This week we welcome Bob Belderbos (@bbelderbos) as our PyDev of the Week! Bob is a co-founder of PyBites. Bob has also contributed to Real Python and he’s a Talk Python trainer. You can learn more about Bob by checking out his website or visiting his Github profile. Let’s spend some quality time getting to know Bob better!

    Can you tell us a little about yourself (hobbies, education, etc):

    I am a software developer currently working at Oracle in the Global Construction Engineering group. But I am probably better known as co-founder of PyBites, a community that masters Python through code challenges.

  • Spyder IDE: Variable Explorer improvements in Spyder 4

    Spyder 4 will be released very soon with lots of interesting new features that you'll want to check out, reflecting years of effort by the team to improve the user experience. In this post, we will be talking about the improvements made to the Variable Explorer.

    These include the brand new Object Explorer for inspecting arbitrary Python variables, full support for MultiIndex dataframes with multiple dimensions, and the ability to filter and search for variables by name and type, and much more.

    It is important to mention that several of the above improvements were made possible through integrating the work of two other projects. Code from gtabview was used to implement the multi-dimensional Pandas indexes, while objbrowser was the foundation of the new Object Explorer.

  • Django security releases issued: 2.2.8 and 2.1.15

    Since Django 2.1, a Django model admin displaying a parent model with related model inlines, where the user has view-only permissions to a parent model but edit permissions to the inline model, would display a read-only view of the parent model but editable forms for the inline.

    Submitting these forms would not allow direct edits to the parent model, but would trigger the parent model's save() method, and cause pre and post-save signal handlers to be invoked. This is a privilege escalation as a user who lacks permission to edit a model should not be able to trigger its save-related signals.

    To resolve this issue, the permission handling code of the Django admin interface has been changed. Now, if a user has only the "view" permission for a parent model, the entire displayed form will not be editable, even if the user has permission to edit models included in inlines.

    This is a backwards-incompatible change, and the Django security team is aware that some users of Django were depending on the ability to allow editing of inlines in the admin form of an otherwise view-only parent model.

  • Guidelines for BangPypers Dev Sprints

    How do you get started on open source programming? How can you contribute to that framework you’ve been itching to add an extra feature to? How do you get guidance and get help pushing your changes to merge upstream?

    If you’ve wondered on the above at least once, then you’re in dire need to attend one of our dev sprints.

  • Trey Hunner: Cyber Monday Python Sales

    Python Morsels is my weekly Python skill-building service.

    I’m offering something sort of like a “buy one get one free” sale this year.

    You can pay $200 to get 2 redemption codes, each worth 12 months of Python Morsels.

    You can use one code for yourself and give one to a friend. Or you could be extra generous and give them both away to two friends. Either way, 2 people are each getting one year’s worth of weekly Python training.

    You can find more details on this sale here.

  • 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.
