Mozilla’s Pyodide becomes an independent and community-driven project

Pyodide, Mozilla’s open-source project for running Python inside a web browser, has become an independent and community-driven project with a new home on GitHub. The company also announced the new 0.17 release as part of its announcement. 

The project aims to bring the Python runtime to the browser via WebAssembly along with NumPy, Pandas, Matplotlib, parts of SciPy and NetworkX. 

According to Mozilla, Pyodide contains the CPython 3.8 interpreter compiled to WebAssembly, which allows Python to run in the browser and it can install any Python package with a pure Python wheel from the Python Package Index (PyPi).

The new version contains major maintenance improvements, a large redesign of the central APIs and careful elimination of error and memory leaks. 

The type translation module was significantly reworked so that the round trip translations of objects between Python and JavaScript produce identical objects.

Previously, issues with round trip translations were caused by implicit change of Python types to Javascript, which surprised users. 

Another new feature is a Python event loop that schedules coroutines to run on the browser event loop which makes it possible to use asyncio in Pyodide. It’s also now possible to await JavaScript Promises in Python and await Python awaitables in JavaScript.

Error handling was also improved so that errors could be thrown in Python and caught in JavaScript and vice-versa. The error translation code is generated by C macros which simplifies implementing and debugging new logic. 

The latest release also completes the migration to the latest version of Emscripten that uses the upstream LLVM backend, reducing significant reductions, package size and execution time. 

Pyodide was originally developed inside Mozilla to allow the use of Python in Iodide to build an interactive scientific computing environment for the web. 

Moving forward, the developers behind Pyodide are focusing on reducing download sizes and initialization times, improving the performance of Python code in Pyodide and simplifying the package loading system.

Difference between Web Designer and Web Developer Neeraj Mishra The Crazy Programmer

Have you ever wondered about the distinctions between web developers’ and web designers’ duties and obligations? You’re not alone! Many people have trouble distinguishing between these two. Although they collaborate to publish new websites on the internet, web developers and web designers play very different roles. To put these job possibilities into perspective, consider the construction of a house. To create a vision for the house, including the visual components, the space planning and layout, the materials, and the overall appearance and sense of the space, you need an architect. That said, to translate an idea into a building, you need construction professionals to take those architectural drawings and put them into practice. Image Source In a similar vein, web development and design work together to create websites. Let’s examine the major responsibilities and distinctions between web developers and web designers. Let’s get going, shall we? What Does a Web Designer Do?

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are declaring 20
