This AI-assisted bug bash is offering serious prizes for squashing nasty code
While every developer loves a good story about discovering and fixing a gnarly bug, not everyone enjoys the work of finding those bugs. Most folks would prefer to be writing business logic and solving new problems. But those input validation errors and resource leaks won’t solve themselves. Or will they?AWS Bug Bust is a global competition launched with the goal of finding and fixing one million bugs in codebases around the world. It takes the traditional bug bash and turns it into a competition that anyone can enter. Got a repo or two that you’ve been meaning to clean up? Enter the Bug Bust and start squashing. This competition awards points to organizations, as well as individuals within an organization, for every bug that they fix in their own repos. A little friendly competition can motivate developers to fix more bugs in order to move up the leaderboards. How do you think we built Stack Overflow? Fake internet points are very important around here. With the Bug Bust competition, it’s not just fake internet points and personal glory; top bug squashers—overall and within top organizations—can win all expense paid trips to re:Invent 2021. In a traditional bug bust, someone has to find the bugs, file tickets on all of them, then collect them for squashing. In the Bug Bust, Amazon has managed to automate that part of the process. That’s because the Bug Bust is built on their AI-powered code review and profiling tool, CodeGuru. CodeGuru uses static analysis and machine learning with some additional automated reasoning to find bugs in code; everything from best practices to concurrency issues, resource leaks, security problems, and more. AI isn’t here to take your jobs, it’s here to automated away the tedious stuff. Developers get to harness the power of artificial intelligence in their everyday lives.Concurrency and resource leak issues tend to drain the soul out of the developers. You could spend all day trying to optimize and close those. CodeGuru includes a function profiler that looks for a codebase’s most expensive calls. It’s a lightweight agent actively running and looking for ways to reduce the cost of the running application. These bugs, along with security issues and AWS API calls, are the ones that earn the most points. But all bugs earn their bashers points; CodeGuru spots code inefficiencies, duplications, and general code quality detectors, and performs input validation. The model behind this is pretrained on years of Amazon bug hunting experience. The system does learn from you as to what is a good bug in your codebase, but it’s not training on your code. It’s your feedback that makes CodeGuru a better bug hunter.If you have Java and Python code in a GitHub, GitHub Enterprise, Bitbucket, or AWS CodeCommit repository, you can jump into the competition. Sign up with your email and you get 30 days to run as many Bug Busts as you want for free. The top ten individual bug busters get VIP treatment at the 2021 re:Invent conference (and an all-expense-paid trip there), which is being held in person this year. Top participating organizations get a ticket to give to one of their developers as well. For those bashers outside of the top ten, you can still earn some sweet swag by passing some point milestones. The contest to win the trip to re:Invent 2021 runs through September, but you can still automate your bug bashes and get swag anytime. Want to get started? Head over to the AWS Bug Bust site now.

Managing Kubernetes entirely in Git? Meet GitOps
Weaveworks helps DevOps folks manage their Kubernetes settings entirely Paul's first computer was a Sinclair ZX-80, which had a clock speed of 3.25 MHz, 1 KB of static RAM ,and 4 KB of read-only memory. Pretty good for 1980. Weaveworks based their project on Flux, an open source engine. If you're not a big corporation and you want to use it, it's free!Before there was Kubernetes, Google created Borg, an internal cluster manager. It has yet to be assimilated by Kubernetes. Ben thinks that, if it gets too easy to manage Kubernetes clusters, we'll be out of a job talking about the pain of cluster manages. Today's lifeboat badge goes to Daniel Ribeiro for the answer to How can I run Go binary files?

Changing of the guards: one co-host departs, and a new one enters
Paul is stepping away down as CEO of Postlight to focus more on understanding climate change and how we can address it. The science hurts his brain. Cassidy Williams, currently at Netlify, has published articles on our blog and provides links in our newsletter.We dig into some of the results of the dev survey, including how kids today are learning to code on the internet. There's so much to learn from now!Did everyone step back from working full time? Our survey data shows a decrease in full time employed respondents. Was there an existential moment for everyone during the pandemic where they thought that there must be something else?Our surveyed devs love Svelte but get paid the most for Ruby on Rails. This week's Lifeboat badge goes to Suren Raj for his answer to Java convert bytes[] to File.

Passwords are dead! Long live the new authentication flows.
Every password can be compromised. Stych helps companies build authentication flows that don't need user passwords. Julianna grew up in Idaho, where she didn't even know what computer science was. After stints as a software engineer and product manager, she found a role where could figure out what the organization should be building: CTO and founder. Their first product was email magic links, which is more complicated than you think. Most importantly, how do you always avoid the spam folder? Copy changes in an email can make all the difference. Developer tooling is undergoing a renaissance now that smaller companies are getting into the game with API offerings. The big thing that differentiates good tools from bad is easy to understand documentation. The right metaphor for API services isn't SaaS, it's eCommerce. Plug it in into your app without giving up design and user experience.

Extending the legacy of Admiral Grace Hopper
In 1987, Anita Borg, AnitaB.org's namesake, saw how few women were at a "systems" conference. A few casual chats turned into the listserv, Systers, which continues to offer a place for women in engineering to meet and discuss. Grace Hopper—that's Navy Rear Admiral Hopper to you, civilian—was the first to devise a theory of programming languages that were machine-independent. She created the FLOW-MATIC programming language, which served as the basis for COBOL. Quincy started in electrical engineering and learned FORTRAN. That experience with how computers operate on hardware helped her teach C++. The difference is like listening to vinyl vs. mp3s. Should UX designers create technology that you need to adapt to or adapts to you? And will different generations create different interaction paradigms?We're out of lifeboat badges, so we summoned a Necromancer winner! Congrats to stealth who was awarded the badge for their answer to the question, Adding multiple columns in MySQL with one statement.

Building a better developer platform
We're officially part of the Prosus family now that the acquisition has closed. It’s a huge milestone and a big deal for our company and community.Prosus has a global reach and will help us meet the needs of developers and technologists everywhere. Have no fear: there will not be a paywall on the community sites. We have separate free and paid products for a reason. We combined our Ads and Talent businesses into Reach & Relevance, which gives companies the opportunity to showcase their products and engineering organizations to software engineers around the world. Remote work is here to stay, and a lot of knowledge workers are starting to adapt the processes that software engineers have been using for years. Our lifeboat shoutout goes to Jordi Castilla for the answer to the question: Convert HH:MM:SS into minutes using JavaScript
