Ethan's book, Once a Bitcoin Miner: Scandal and Turmoil in the Cryptocurrency Wild West, is available now.The metaverse isn’t just inevitable; it’s already here (and it has a booming real estate market).As we move more of our lives online onto platforms controlled by increasingly powerful digital giants, Ethan explains the democratizing power of cryptocurrency and blockchain. On the other hand, China’s new digital currency (government-issued but crypto-inspired) raises questions about privacy and surveillance. And why did China declare all cryptocurrency transactions illegal?Is crypto the new oil—an environmental disaster burning all this energy in the face of climate change? Bitcoin was using  as much energy as Finland or Pakistan.

We kick things off by weighing the merits of two gender-neutral regional pronouns: the familiar y’all and the under appreciated yinz. Now that’s covered...The global population of developers will hit 45 million by 2030, up from 26.9 million in 2021 (EDC). What platforms will they want to build on?Did Kubernetes solve all your problems? Did it create new ones?It seems there’s always an XKCD relevant to our conversation. Today, it’s How standards proliferate.

Maxwell, a solution architect at xMatters, took a winding road to get to where he is. After a computer engineering education, he held jobs as field support engineer, product manager, SRE, and finally his current role as a solutions architect, where he serves as something of an SRE for SREs, helping them solve incident management problems with the help of xMatters. When he moved to the SRE role, Maxwell wanted to get back to doing technical work. It was a lateral move within his company, which was migrating an on-prem solution into the cloud. It’s a journey that plenty of companies are making now: breaking an application into microservices, running processes in containers, and using Kubernetes to orchestrate the whole thing. Non-production environments would go down and waste SRE time, making it harder to address problems in the production pipeline. At the heart of their issues was the incident response process. They had several bottlenecks that prevented them from delivering value to their customers quickly. Incidents would send emails to the relevant engineers, sometimes 20 on a single email, which made it easy for any one engineer to ignore the problem—someone else has got this. They had a bad silo problem, where escalating to the right person across groups became an issue of its own. And of course, most of this was manual. Their MTTR—mean time to resolve—was lagging. Maxwell moved over to xMatters because they managed to solve these problems through clever automation. Their product automates the scheduling and notification process so that the right person knows about the incident as soon as possible. At the core of this process was a different MTTR—mean time to respond. Once an engineer started working to resolve a problem, it was all down to runbooks and skill. But the lag between the initial incident and that start was the real slowdown. It’s not just the response from the first SRE on call. It’s the other escalations down the line—to data engineers, for example—that can eat away time. They’ve worked hard to make  escalation configuration easy. It not only handles who's responsible for specific services and metrics, but who’s in the escalation chain from there. When the incident hits, the notifications go out through a series of configured channels; maybe it tries a chat program first, then email, then SMS. The on-call process is often a source of dread, but automating the escalation process can take some of the sting out of it. Check out the episode to learn more.

The infrastructure that networked applications lives on is getting more and more complicated. There was a time when you could serve an application from a single machine on premises. But now, with cloud computing offering painless scaling to meet your demand, your infrastructure becomes abstracted and not really something you have contact with directly. Compound that problem with with architecture spread across dozens, even hundreds of microservices, replicated across multiple data centers in an ever changing cloud, and tracking down the source of system failures becomes something like a murder mystery. Who shot our uptime in the foot? A good observability system helps with that. On this sponsored episode of the Stack Overflow Podcast, we talk with Greg Leffler of Splunk about the keys to instrumenting an observable system and how the OpenTelemetry standard makes observability easier, even if you aren’t using Splunk’s product. Observability is really an outgrowth of traditional monitoring. You expect that some service or system could break, so you keep an eye on it. But observability applies that monitoring to an entire system and gives you the ability to answer the unexpected questions that come up. It uses three principal ways of viewing system data: logs, traces, and metrics.Metrics are a number and a timestamp that tell you particular details. Traces follow a request through a system. And logs are the causes and effects recorded from a system in motion. Splunk wants to add a fourth one—events—that would track specific user events and browser failures. Observing all that data first means you have to be able to track and extract that data by instrumenting your system to produce it. Greg and his colleagues at Splunk are huge fans of OpenTelemetry. It’s an open standard that can extract data for any observability platform. You instrument your application once and never have to worry about it again, even if you need to change your observability platform. Why use an approach that makes it easy for a client to switch vendors? Leffler and Splunk argue that it’s not only better for customers, but for Splunk and the observability industry as a whole. If you’ve instrumented your system with a vendor locked solution, then you may not switch, you may just let your observability program fall by the wayside. That helps exactly no one. As we’ve seen, people are moving to the cloud at an ever faster pace. That’s no surprise; it offers automatic scaling for arbitrary traffic volumes, high availability, and worry-free infrastructure failure recovery. But moving to the cloud can be expensive, and you have to do some work with your application to be able to see everything that’s going on inside it. Plenty of people just throw everything into the cloud and let the provider handle it, which is fine until they see the bill.Observability based on an open standard makes it easier for everyone to build a more efficient and robust service in the cloud. Give the episode a listen and let us know what you think in the comments.

Isaac's piece, Code quality: a concern for businesses, bottom lines, and empathetic programmers, ran recently on the Stack Overflow blog. A simple metric for code quality code be how easy is it to delete any given piece of code. There's no algorithmic way to judge quality code, but experienced engineers know it when they see it. Jeff Atwood's Performance is a Feature blog post gets a lot of mileage with our writers. But code quality isn't on the same axis; it's not a feature you can prioritize. It's part of the development process.

Right now, most development teams provide visibility into their overall process and lifecycle through standup meetings and spreadsheets. It can be a painfully manual process that uses up valuable engineering time. Value stream management aims to solve that by mapping out the entire software development life cycle and providing visibility into areas where things are breaking down or getting stuck. It borrows ideas from Agile and the automate-all-the-things attitude from DevOps to ensure engineering teams are moving fast with direction, avoiding bottlenecks, and reaching the the key objectives management planned weeks ago.In this episode, we chat with Nick Mathison and Sylvan Carbonell from HCL Software DevOps about value stream management and how their product, HCL Accelerate, brings visibility into the entire gamut of the SDLC, from the request coming in from a customer to deploying code to the production servers. At the foundation of this process is a good map of the company’s value stream. Think of it as bringing all your teams together to map out the entire workflow of your development cycle on a whiteboard, from receiving feature requests and bug reports, assigning out tickets, merging code, requesting code reviews, passing build tests, QA processes, and finally deploying to production. The value stream map brings that whiteboard to life. Once the process is mapped out and the data flows revealed, it is very easy to track where the work is at any given time and how fast it is flowing through the value stream. Every company has little idiosyncrasies that make their process unique: their specific slowdowns, time sinks, and manual approvals that grind development to a halt. Value stream management spots those and helps you eliminate them. In a value stream, you’re no longer watching individual devs; your best metrics cover the “two-pizza team,” a team small enough to be fed by two pizzas. This team’s interactions—working through epic tickets, code reviews, internal support, etc.—provides the best metrics to identify ways to increase the value that a team provides. With many technology companies working fully remotely during the pandemic, understanding each team’s process is critical. HCL offers a way to accomplish this without bringing lengthy standups back in the picture.Start benefiting from value stream management today with the forever-free Community Edition of HCL Accelerate.

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.

This year over 80,000 respondents took the time to share their feedback on the tools and trends that are shaping software development.We learned a lot about the way developers learn. For the rising cohort of coders under the age of 18, online resources like videos and blogs are more popular than books and school combined, a statistic that doesn’t hold for any of our other age cohorts. Roughly a third of respondents responded to our question on mental health. This is twice the percentage that offered feedback in 2020 and may reflect a growing awareness of the importance of mental health’s and the impact of the ongoing pandemic.Another trend that may be linked to the pandemic is work status. We see a greater percentage of respondents working part-time or in school, while those indicating full time employment decreased. This may reflect the effects of the pandemic, which saw workers from all industries stepping back and reevaluating their relationship to a five day work week and in-person employment.Check out the full results of the 2021 Dev Survey here.

As explained in this piece, "A headless CMS is a back-end only content management system (CMS) built from the ground up as a content repository that makes content accessible via a RESTful API or GraphQL API for display on any device." Shopify has leaned hard into GraphQL and APIs in general. The goal, as Coates describes it, is to allow developers to bring their own stack to the front-end, but provide them with the benefits of Shopify's back-end, like edge data processing for improved speed  at global scale. Shopify also offers a wealth of DevOps tooling and logistical support when it comes to international commerce. We also discuss Liquid, the flexible template language Shopify uses for  building web apps.Our lifeboat badge of the week goes to chunhunghan for answering the question: How to customize the switch button in a flutter?
