  • EuroPython 2020: Our keynotes

    Conference tickets are available on our registration page. We hope to see lots of you at the conference from July 23-26. Rest assured that we’ll make this a great event again — even within the limitations of running the conference online.

  • Full Stack Python: How to Report Errors in Flask Web Apps with Sentry

    Flask web applications are highly customizable by developers thanks to the framework's extension-based architecture, but that flexibility can sometimes lead to more errors when you run the application due to rough edges between the libraries.

    Reporting errors is crucial to running a well-functioning Flask web application, so this tutorial will guide you through adding a free, basic Sentry configuration to a fresh Flask project.

  • PyCharm EAP#3 is out!

    PyCharm EAP #3 is out and it’s almost releasing time!! If you are like us you are also looking forward to the end of the month! We have been talking about new features for the last month and today we will take a deeper look into two very exciting ones. For the full list, check our release notes.

  • The Home Stretch - Building SaaS #63

    In this episode, we return to the homeschool application that I’m building. I’m in the final stretch of changes that need to happen to make the product minimally viable. We worked on a template, wrote some model methods, and did a bunch of automated testing.

    We started by adding students to the context of the students index page. With the students in the context, we updated the index page to display the list of students.

    After the students were available, we had to check their enrolled status in a school year. That logic doesn’t belong in the template so we worked out the changes needed for the view.

  • py.CheckIO: Find out more about Python by searching the solutions

    As you might have noticed, for two weeks we haven’t made our usual newsletter mailouts. But we definitely weren’t wasting any time. CheckiO team was actually preparing some important updates, which we want to share with you.

    That’s a common knowledge that CheckiO originated from the idea of practical learning through shared solutions. This means that in our portals you can learn not only by solving the coding tasks, but also by checking out and analyzing the solutions made by other users. In view of this, our next step became a logical continuation of this ideology.

    Since the creation of CheckiO, we’ve gathered nearly half a million of different solutions. Now, using the Solution Search feature, which becomes available from the 2nd Level, you can easily find any solution you need. Like you can look for the usage examples of an itertools.groupby function. You just need to enter it into the search field and you’ll see multiple solutions. Or you can type ‘itertools’ and you’ll be presented with all of the solutions where this module had been used. It’s fast, efficient and quite handy. The feature is still in the beta testing mode though.

  • Data science workflows on Kubernetes with Kubeflow pipelines: Part 2

    Kubeflow Pipelines are a great way to build portable, scalable machine learning workflows. It is a part of the Kubeflow project that aims to reduce the complexity and time involved with training and deploying machine learning models at scale. For more on Kubeflow, read our Kubernetes for data science: meet Kubeflow post.

    In this blog series, we demystify Kubeflow pipelines and showcase this method to produce reusable and reproducible data science.

    In Part 1, we covered WHY Kubeflow brings the right standardization to data science workflows. Now, let’s see HOW you can accomplish that with Kubeflow Pipelines.

    In Part 2 of this blog series, we’ll work on building your first Kubeflow Pipeline as you gain an understanding of how it’s used to deploy reusable and reproducible ML pipelines.

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.
