  • Python 3.8.5 : PyEphem astronomy library for Python - part 001.
  • Creating multiple windows in PyQt5/PySide2

    In an earlier tutorial we've already covered how to open dialog windows. These are special windows which (by default) grab the focus of the user, and run their own event loop, effectively blocking the execution of the rest of your app.

    However, quite often you will want to open a second window in an application, without interrupting the main window -- for example, to show the output of some long-running process, or display graphs or other visualizations. Alternatively, you may want to create an application that allows you to work on multiple documents at once, in their own windows.

    It's relatively straightforward to open new windows but there are a few things to keep in mind to make sure they work well. In this tutorial we'll step through how to create a new window, and how to show and hide external windows on demand.

  • Real Python Podcast Interview

    I am on the latest Real Python podcast where I talk about my ReportLab book, wxPython, and lots more.

    The podcast episode that I take part in is called Episode 20: Building PDFs in Python with ReportLab. Check it out and feel free to ask questions in the comments.

  • Real Python Episode 20: Building PDFs in Python with ReportLab

    Have you wanted to generate advanced reports as PDFs using Python? Maybe you want to build documents with tables, images, or fillable forms. This week on the show we have Mike Driscoll to talk about his book “ReportLab - PDF Processing with Python.”

    Mike is an author of multiple books about Python, and has recently re-written his Python 101 book. He is also a member of the Real Python team and has written several articles for the site. Along with our discussion about ReportLab and PDFs, Mike talks about being a self-published author. We also talk briefly about his favorite Python GUI framework.

  • Bring your Mycroft AI voice assistant skill to life with Python

    In the first two articles of this series on Mycroft, an open source, privacy-focused digital voice assistant, I covered the background behind voice assistants and some of Mycroft's core tenets. In Part 3, I started outlining the Python code required to provide some basic functionality to a skill that adds items to OurGroceries, a grocery list app. And in Part 4, I talked about the different types of intent parsers (and when to use each) and expanded the Python code so Mycroft could provide audible feedback while working through the skill.

    In this fifth article, I will walk through the remaining sections required to build this skill. I'll talk about project dependencies, logging output for debugging purposes, working with the Mycroft web UI for setting values (such as usernames and passwords), and how to get this information into your Python code.

Linux Foundation Broadens Relationship With Surveillance

  • Facebook joins The Linux Foundation as a platinum member

    Most web-based companies are built on Linux and open-source software. Two-billion member social network Facebook is no different. For years, Facebook has not only relied on open-source, it's been an active contributor to major open-source projects. These include the React JavaScript library; the Open Compute Project, which open sources data-center hardware; and Linux's cGroup2 container software. Now Facebook is joining The Linux Foundation membership at the Platinum level. [...] While Facebook has been criticized for how it deals with privacy and politics, it has impeccable open-source credentials. It was already the lead contributor of many Linux Foundation-hosted projects, such as Presto, GraphQL, Osquery, and ONNX. The company also employs many Linux kernel key developers and maintainers.

  • Amundsen Joins LF AI as New Incubation Project

    LF AI Foundation (LF AI), the organization building an ecosystem to sustain open source innovation in artificial intelligence (AI), machine learning (ML), and deep learning (DL), today is announcing Amundsen as its latest Incubation Project.

  • LF AI Accepts Amundsen as Incubation Project

    The Amundsen data discovery project has joined the LF AI as an incubation project. Amundsen is a data discovery and metadata engine aiming to improve the productivity of data analysts, data scientists and engineers by indexing data resources. “Think of it as Google search for data,” the LF AI announcement said.

Graphics: Mesa 20.2 RC2 and DXVK 1.7.1

  • mesa 20.2.0-rc2
    Hi list,
    
    Available today is mesa 20.2.0-rc2. This is the second release candidate for
    the 20.2 release. Currently our open to close ratio on blocking bugs is looking
    really good. This release is dominated by changes to radeonsi, radv, and aco,
    with a few additional changes sneaking in for freedreno, meson,  etnaviv,
    st/mesa, anv, and a few utility fixes.

  • Mesa 20.2-RC2 Released With Many Fixes For RadeonSI + RADV Drivers

    The second weekly release candidate of the forthcoming Mesa 20.2 is now available for testing. Mesa 20.2 is aiming for release around the end of August or early September depending upon how the bug situation plays out. This quarterly feature release to Mesa3D brings many new Vulkan extensions, the RADV driver using ACO by default, initial support for Navi 2 GPUs, initial support for Intel Rocket Lake and DG1, OpenGL 4.3 for LLVMpipe, and much more as outlined in last week's article.

  • DXVK 1.7.1 Released With Many Game Fixes For Direct3D Over Vulkan

    It's been nearly three months without a new DXVK release for mapping Direct3D 9/10/11 atop the Vulkan API while finally today there is a big feature release out. DXVK 1.7.1 was released a few minutes ago as the first update since May. While the version number isn't significant, this version does have many changes.

  • Direct3D to Vulkan translation layer DXVK 1.7.1 is out, lots of game fixes

    After a few months since 1.7 went out, DXVK 1.7.1 is now live to further improve Direct3D to Vulkan translation. This is the project that helps to power Proton, the compatibility layer for Steam Play. This release adds support for newer Vulkan extensions, fixes bugs and has new GPU driver requirements. On the driver side, the VK_EXT_transform_feedback extension is now required which has been supported in drivers on Linux since late 2018 / early 2019. Specifically you will need at least NVIDIA 415.22 and for AMD / Intel it looks like Mesa 19 covers both.

Devices/Embedded: Raspberry Pi and Android Devices

  • Indoor air quality HAT for Raspberry Pi boasts high-res TVOC sensor

    Avnet’s $49.95 “Renesas ZMOD4410 Indoor Air Quality HAT for Raspberry Pi” can be used to measure volatile organic compounds, humidity, and temperature, as well as estimate carbon dioxide levels. Avnet has launched a Renesas ZMOD4410 Indoor Air Quality HAT for Raspberry Pi (AES-RHSEN-ZM44-G) that joins other indoor air quality measurement add-ons for the Pi including Metriful’s $44.50 Sense module and Pimoroni’s $57 Enviro+ pHAT. The ZMOD4410 HAT lacks some of the extras of those boards, but appears to offer a higher quality total volatile organic compound (TVOC) sensor with its Renesas ZMOD4410, which offers resolution ranging from parts-per-billion to parts-per-million.

  • Tiny module and dev kit run RT Linux on STM32MP1

  • Learn Any Programming Language with This Learning Plan

    All it takes to master any programming language is the right learning plan. If you know anything about programming you should be aware that often you can’t tell whether what you are doing is wrong until it’s too late. That’s what makes programming a frustrating skill to master — long hours doing the wrong things. But hey, whether you want to make programming your full-time job or just a hobby, you can always make the learning curve less steep. The secret to getting it right with coding is this: have a learning plan! While the plan will not do the hard lifting for you, it will definitely provide the much-needed elbow grease to keep you grounded and focused as you learn programming.

  • Matt Layman: Rendering Calendars - Building SaaS #68

    In this episode, I worked on rendering a calendar of important events in a school year. We built out the appropriate data structures, and I wrote some new model methods and added tests. On the last stream, I created a new model to track breaks in the school year. The app now shows the calendar for the school year, and I want to display the breaks on the calendar. Before digging too far into the code, I provided my thoughts about using Docker for development from a question that came from the chat.
