  • Fun with LEDs and CircuitPython

    Nina Zakharenko has been programming for a long time; when she was young she thought that "the idea that I could trick computers into doing what I tell them was pretty awesome". But as she joined the workforce, her opportunities for "creative coding" faded away; she regained some of that working with open source, but tinkering with hardware is what let her creativity "truly explode". It has taken her years to get back what she learned long ago, she said, and her keynote at PyCon 2019 was meant to show attendees the kinds of things can be built with Python—starting with something that attendees would find in their swag bag.

    As part of her shift in thinking, she realized that "software doesn't have to be serious"; it can be used to make art, for example. But she also realized that hardware doesn't need to be serious either, putting up a clip from a YouTube video of "The Breakfast Machine" created by "an incredible maker", Simone Giertz. She showed pictures of some of her own projects (which can be seen in her Speaker Deck slides), such as an Arduino-based iridescent LED headdress.

  • Best 50 Python Books for Programmers with All Skill Sets

    Python has been one of my favorite programming languages ever since I started working with it. While writing this article on Python books, it reminds me of my early days with Python and searching for resources to get going with this simple but amazing programming language. Since its early days, Python has come a long way to establish its dominance in the field of data science and machine learning. For any programming task you can use Python, right from application development to debugging.Python is a powerful programming language and its contribution to the field of data science is second to none. From a simple file search computer program to the script behind self-driving cars, there is data science backed by Python. There is no surprise there is a huge demand for data science experts in today’s tech savvy world.

  • Broadcasting messages to WebSocket API clients

    Invoking individual WebSocket connections has been supported since Zato 3.0 and Zato 3.1 adds new functionality on top of it - message broadcasting - which lets one notify all the clients connected to a particular channel. Here is how to use it.

  • Building a Todo App with Flask in Python

    In this tutorial, we are going to build an API, or a web service, for a todo app. The API service will be implemented using a REST-based architecture.

  • How to create, package and sign a Firefox web extension

    Firefox is one of the most used web browser in the world: it's a free and open source software built by the Mozilla foundation, and it's available for all the major operating systems. The browser has all the features that nowadays are considered standard: tabbed browsing, private navigation, a synchronization system and its functionalities can be extended using third party addons written in Javascript. In this tutorial we will see how to create, build and sign a simple web extension.

  • Socorro: May 2019 happenings

    Socorro is the crash ingestion pipeline for Mozilla's products like Firefox. When Firefox crashes, the crash reporter collects data about the crash, generates a crash report, and submits that report to Socorro. Socorro saves the crash report, processes it, and provides an interface for aggregating, searching, and looking at crash reports.

Software: Genome Browsers, EtherCalc and Curl

  • Best Free Web Based Genome Browsers

    In the fields of molecular biology and genetics, a genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than 3 billion DNA base pairs—is contained in all cells that have a nucleus. The study of the genome is called genomics. In bioinformatics, a genome browser is a graphical interface for display of information from a biological database for genomic data. They are important tools for studying genomes given the vast amounts of data available. They typically load very large files, such as whole genome FASTA files and display them in a way that users can make sense of the information there. They can be used to visualize a variety of different data types. Genome browsers enable researchers to visualize and browse entire genomes with annotated data including gene prediction and structure, proteins, expression, regulation, variation, comparative analysis, etc. They use a visual, high-level overview of complex data in a form that can be grasped at a glance and provide the means to explore the data in increasing resolution from megabase scales down to the level of individual elements of the DNA sequence. There’s a wide range of web based genome browsers. We’re going to restrict our selection to the top 4.

  • Get going with EtherCalc, a web-based alternative to Google Sheets

    EtherCalc is an open source spreadsheet that makes it easy to work remotely and collaborate with others.

  • Daniel Stenberg: curl 7.65.2 fixes even more

    Six weeks after our previous bug-fix release, we ship a second release in a row with nothing but bug-fixes. We call it 7.65.2. We decided to go through this full release cycle with a focus on fixing bugs (and not merge any new features) since even after 7.65.1 shipped as a bug-fix only release we still seemed to get reports indicating problems we wanted fixed once and for all. Download curl from curl.haxx.se as always! Also, I personally had a vacation already planned to happen during this period (and I did) so it worked out pretty good to take this cycle as a slightly calmer one. Of the numbers below, we can especially celebrate that we’ve now received code commits by more than 700 persons!
