The Stack Overflow Podcast

When most people talk about Web3 or cryptocurrencies and related technologies, they usually mean blockchains. But blockchain is only the first generation of distributed ledger technology (DLT). As with any new technology, once people see how it works, new generations come along rapidly to address the faults in the previous ones. On this sponsored episode of the podcast, Ben and Ryan chat with Matt Woodward, head of developer relations at Swirlds Labs. Swirlds Labs created the Hedera ecosystem, a DLT built on a hashgraph, not a blockchain. We chat about what the difference is between a blockchain and a hashgraph, Hedera’s focus on environmental sustainability, and why the Web3 version of “Hello, World!” takes a little more effort. Show notesHedera’s hashgraph is a third-generation DLT: it’s an open-source consensus algorithm and a data structure that uses a direct acyclic graph and two novel inventions, the gossip about gossip protocol and virtual voting. Where Bitcoin can only handle between three and seven transactions per second, a hashgraph can support upwards of 10,000. There’s been a lot of talk about the environmental impact of cryptocurrencies. Woodward says that a single Bitcoin transaction uses 1000kW-hours—the equivalent of driving a Tesla Model S 5,500 km—while Hedera uses 160 MW-hours of energy per year, about 2.5 million times less.Congrats to the winner of a Stellar Question badge, g.revolution, for their question What is an anti-pattern? 100 users saved it for later. Find out more about Hedera and hit the start button. Connect with Matt, Ben, or Ryan on Twitter.

In today’s podcast, Matt, Ceora, and Cassidy reflect on Cara’s founder journey.Cara shares her experiences living in New York and San Francisco— and why she and her co-founder ultimately located Stashpad in North Carolina.She elaborates on the exact steps that she took to pivot her startup following limited initial interest in V1 of the product.Despite being in the Bay Area and working at Twilio, she was struggling to meet people because her full brain power was going to her products.She shares what it was like for her and her co-founder to hire Stashpad’s first employees.The group discusses Stashpad’s pathway to monetization in the context of developers wanting free tools.Follow, Ceora, Matt, Cassidy, and Cara.Marchingband gets today’s lifeboat badge for their answer to the question about running C or C++ code from Node.js in an efficient way. 

When Foursquare launched in 2009, the app was consumer facing, letting you know where friends had checked in and what spots might appeal to you. People competed to be the “mayor” of certain locations and built guides to their favorite neighborhoods., The service expanded to allow merchants to offer discounts to frequent guests and track foot traffic in and out of the stores. While you can still use the Swarm app to find the best Manhattan in Manhattan, the company realized that real estate and data share the same three key rules: location, location, location. On this sponsored episode of the podcast, Ben and Ryan talk with Vin Sharma, VP of Engineering at Foursquare, about how they’re finding the atomic data that makes up their location data—their location data—and going from giving insight to individual app users about the locations around them to APIs that serve these location-based insights to developers at organizations like Uber, Nextdoor, and Redfin, who want to build location based insights and features into their own apps. Show notesIf you still want to check in at your local bakery and remember all the place you’ll go, the original Foursquare app is now Swarm. If you’re looking to build on their data instead, you can start with their developer documentation. They have almost 70 location attributes that they are starting to deconstruct and decompose into fundamental building blocks of their location data. Like data primitives—integers, booleans, etc.—these small bites of data can be remade with agility and at scale. Through the recent acquisition of Unfolded, Foursquare allows you to visualize and map location data at any scale. Want to see patterns across the country? Zoom out. Want to focus on a square kilometer? Zoom in and watch the data move. Today’s lifeboat shoutout goes to Rohith Nambiar for their answer to Visual Studio not installed; this is necessary for Windows development. You can find Vin Sharma on Twitter. 

The group laughs about setting up JIRA workflows and Trello boards for our family lives—Matt says heck no.Ceora speaks to the power of homelabbing as a way to gain profitable skills. JJ talks about the VPN system he has running on his phone to access his home network using tools like WireGuard and ZeroTier.Cassidy suggests setting up a personal knowledge base as a second brain (and recommends Obsidian). JJ shares how homelabbing is popular among kids under 18 as a pathway for them to get into the tech industry.Follow, Ceora, Matt, Cassidy, and JJ.High fives to Lifeboat Badge winner Manquer for the answer to his question How can I upgrade the Yii 1.x version to the Yii 2.0 latest release version?

Katzgraber reflects on his time as a university professor up until 2020 and why he switched to working at Amazon.He walks us through a quantum computing challenge that he hosted with BMW, through his role at Amazon (and what real world applications he sees emerging from these types of collaboration experiments).We discuss what inspires him to stay curious — raising the bar for scientific research, crowdsourcing breakthroughs, and opening up the playing field for more people to jump in.Follow Ben, Ryan, Matt, and Helmut.‘Til next time, all.

We got the chance to sit down with Guillermo Ruach, Guillermo Rauch, CEO of Vercel and co-creator of Next.JS, about the news coming out of today's conference. The most interesting was a new product called Turbopack. You can read more about it here.  

Freund reflects on his early days at Applied Materials, where he worked on a machine that inspected silicon wafers.It was in this early role that Freund gained an appreciation for rigorous software testing protocols in the manufacturing process.At WeWork, Freund was fascinated by the idea of a full stack business, which is a business building itself.While Freund officially launched Wilco in 2021, the origin story for the company dates back to 2013 when he was hiring and managing a team of engineers—he saw a need in the market to help developers build critical skills to problems-solve in real-time.You can think of Wilco as the equivalent of a flight simulator for engineers.Shoutout to Lifeboat Badge winner Zico for their awesome answer to the question, “Hiding sensitive information in response”Follow On and Ben.

John explains that Web3 is about the convergence of technology, economics, and social trends.He elaborates that foundations begin with service-based architecture (SOA), the notion of how to design loosely coupled systems that consist of economic services and components.He goes on to explain how DeFi represents this thinking of a loose composition of services.With all of this, blockchain brings together technology and economic incentives into a holistic equation—people contribute because they want to contribute.Nonsense it is not, says baby Yoda.Crypto isn’t the end game. It’s a segue along the way.Follow Ben, Matt, and John.Learn more about the Global Blockchain Business Council and John’s company, ngEnterprise.Speaking of awesomeness, we’d like to give a shout out to Stellar Question Badge winner GateKiller for asking a question “How can I get the DateTime for the start of the week?” that has been bookmarked by a hundred people.
