  • Building FunctionTrace, a graphical Python profiler

    Firefox Profiler became a cornerstone of Firefox’s performance work in the days of Project Quantum. When you open up an example recording, you first see a powerful web-based performance analysis interface featuring call trees, stack charts, flame graphs, and more. All data filtering, zooming, slicing, transformation actions are preserved in a sharable URL. You can share it in a bug, document your findings, compare it side-by-side with other recordings, or hand it over for further investigation. Firefox DevEdition has a sneak peek of a built-in profiling flow that makes recording and sharing frictionless. Our goal is to empower all developers to collaborate on performance – even beyond Firefox.

    Early on, the Firefox Profiler could import other formats, starting with Linux perf and Chrome’s profiles. More formats were added over time by individual developers. Today, the first projects are emerging that adopt Firefox for analysis tools. FunctionTrace is one of these, and here is Matt to tell the story of how he built it.

  • Python Community Interview With Russell Keith-Magee

    Today I’m joined by Russell Keith-Magee. Russell is a Django core developer and the founder and maintainer of the BeeWare project. In the interview, we talk about his mission to help Python become a feasible option for writing and packaging mobile applications as well as his passion for open source projects. We also touch on his PyCon 2020 talk, which has since been recorded and uploaded to the PyCon YouTube channel.

  • Teach kids Python by building an interactive game

    Python has earned a reputation as a wonderful beginner programming language. But where does one begin?

    One of my favorite ways to get people interested in programming is by writing games.

    PursuedPyBear (ppb) is a game programming library optimized for teaching, and I recently used it to teach my children more about my favorite programming language.

    The Jupyter project is a browser-based Python console, initially designed for data scientists to play with data.

    I have a Jupyter Notebook designed to teach you how to make a simple interactive game, which you can download from here. In order to open the file, you will need to install the latest Jupyter project, JupyterLab.

  • Python Bytes: #182 PSF Survey is out!
  • Episode #265: Why is Python slow?

    The debate about whether Python is fast or slow is never-ending. It depends on what you're optimizing for: Server CPU consumption? Developer time? Maintainability? There are many factors. But if we keep our eye on pure computational speed in the Python layer, then yes, Python is slow.

    In this episode, we invite Anthony Shaw back on the show. He's here to dig into the reasons Python is computationally slower than many of its peer languages and technologies such as C++ and JavaScript.

  • Montreal Python User Group: Montéal-Python 77 – Harmonious Serinette

    Pythonistas, Pythonistinas, we sneaked out of our burrows and crawled the Montréal-Python 76 gathering. We would have preferred to meet in person, but the virtual conference revived our passion for Python nonetheless.

    We had a lot of fun, and therefore we decided to organize a second virtual event! Montréal-Python 77, Harmonious Serinette, will take place on June 1st, 2020 at 5:30pm, Montreal time. We keep the online conference formula with live streaming on our Youtube channel. We want to make this more exciting than just watching a recorded talk by having numerous live demos and lots of interactions on Slack. Prepare your questions!

  • 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.
