1. Firefox 71 is now available. This latest major release comes with a number of new developer tools and features, including the web socket message inspector, console multi-line editor mode, network panel full-text search, and inline variable previewing in the JavaScript Debugger. The new version also boasts a much faster DevTools load time; in one console test, the Mozilla team reports DevTools got a 40% improvement while times across every panel went up by up to 15 percent. In addition, Firefox 71 offers new web platform features like CSS subgrid, column-span, Promise.allSettled, and the Media Session API. - MOZILLA HACKS

2. The author of the most copied Stack Overflow Code Snippet says he has found bugs in the original code he published. In 2010, Igor Mukhin asked the community how he could convert byte size into a human-readable format in Java, with fellow Stack Overflow user aioobe, whose actual name is Andreas Lundblad, answering with a snippet that would be copied and pasted by many into production codebases worldwide. However, Lundblad, a computer science PhD who has worked at both Oracle and Palantir, says he has since found flaws in the original code. He realized his code was buggy after ironically recently finding out in a study titled "Usage and Attribution of Stack Overflow Code Snippets in GitHub Projects" that his answer was the most copied on the platform. Lundblad has since fixed the answer, however, and you can check out the updated, correct code snipped with his explanations here. At the end of the post containing his updated answer, however, Lundblad cautions fellow developers to always "test all edge cases, especially for code copied from Stack Overflow." - PROGRAMMING GUIDE

3. Amazon Web Services (AWS) has released a preview version of its new machine learning service, Amazon CodeGuru. CodeGuru provides automated code reviews and recommendations to improve issues including resource leaks, potential concurrency race conditions, and more. It also identifies and gives advice about the "most expensive lines of code" that hurt application performance the most. According to the tech giant, CodeGuru is able to do this because it is "powered by machine learning, best practices, and hard-learned lessons across millions of code reviews and thousands of applications profiled on open source projects and internally at Amazon." At the moment, the new service only provides support for Java applications, but Amazon says it will expand to more languages "soon." Information on pricing is available here. - AWS

4. Former Google software engineers Rebecca Rivers and Laurence Berland, as well as two other ex-Googlers, are filing federal charges against the tech giant. The news comes after Google fired all four, arguing they'd violated policies concerning accessing and sharing internal documents and calendars. However, the four allege Google fired them to quash worker organizing, thus violating federal labor laws. “It’s not about us, but intimidating everyone else,” added Laurence Berland, another of the fired Googlers. “They want us afraid, they want us resigned, and they want us cynical.” - THE GUARDIAN

5. Uber has introduced and open-sourced React View, an interactive playground for components the company uses internally.  According to Uber's development team, "React View is a set of tools that aspires to close the gap between users, developers and designers of component libraries." A component itself, React View can be used by developers in all React apps to easily showcase and share their components, and even edit the props or code used to display it. - BASE WEB | GITHUB

6. Node v13.3.0 is now available. This latest release introduces initial WASI support, reworked experimental recursive, made maximum header size configurable per-stream or per-server, and more. It also comes with a number of bug fixes. - NODE.JS

7. Amazon announced it has launched a Local Zone in Los Angeles. According to Amazon Web Services (AWS), this is an AWS infrastructure deployment that offers select AWS services to certain areas. As it provides low latency to apps accessed from LA and other areas in Southern California, it is particularly relevant to apps in the media and entertainment, ad-tech, electronic design automation, and other industries. - AWS

8. Metaflow, Netflix's Python framework for data science, is now available open-source. The framework offers a unified API to the infrastructure stack that is necessary to deploy data science projects to production. The engineering team at Netflix originally created Metaflow to improve data scientists' productivity while working on projects ranging from classical statistics to state-of-the-art deep learning. - METAFLOW

9. Instana announced it now it offers Node.js functions for AWS Lambda. This means users can now trace serverless Node.js functions running on AWS Lambda. "By providing Native Node.js tracing on AWS Lambda, Instana helps application stakeholders like DevOps see how individual functions are performing call by call, but also provides the necessary details developers need to make their code perform as expected," said Mirko Novakovic, co-founder and CEO of Instana. - SDTIMES

10. Check out JSONCrush. This is a new tool you can use to compress JSON into URI friendly strings so they can be shared and bookmarked easily. You can try a live demo here. - JSONCRUSH / GITHUB
