In this month’s episode, host Tamara Kahn speaks to Peter Ullrich of HydroDAO, a community bringing together all of the stakeholders in the water industry. Tamara talks to Peter about how he learned about water and human health while studying medicine and followed his interest in water to a program that led him to co-founder Stuart Rudick. Now they work to bring together entrepreneurs, funders, experts, and large water users with the goal of solving water challenges through their community HydroDAO. They are also raising a fund to invest in promising early growth-stage companies. Listen to hear an optimistic conversation about uniting water industries across silos, including ocean industries, and about the next generation’s work to align their careers and their financial choices with their values.

Meet Peter Ullrich: Education, collaboration, and investment to solving water challenges | Wave Makers

We talk with Peter Ullrich about his experience sending SMS messages from a Raspberry Pi Zero using Nerves. We cover what went well, what didn’t and get a glimpse into the current state of Nerves for a newbie when dealing with hardware. Peter also tried Livebook for Nerves and had a great experience with that. We discuss the challenges of hardware systems dealing with the “real world” but see how Elixir makes the process easier to model and think about.

63: SMS Texting in Nerves with Peter Ullrich

There are two factors that limit the rate at which transactions are accepted into the Bitcoin blockchain: block time and block size. Block time defines how often a new block is appended onto the blockchain. Block size defines how many transactions fit into a new block. As of March 2018, the current block time and block size allow for about 7 transactions per second to be accepted into the Bitcoin blockchain. In today’s episode, we discuss the technical limitations of the Bitcoin blockchain and some potential solutions to scalability: SegWit and lightning network. Today’s guest is Peter Ullrich, the host of Explain Blockchain. Explain Blockchain is a podcast I have found tremendously useful as I have started to learn about blockchains. He provides thorough, technical explanations of complicated topics, and I recommend subscribing to his show, and listening to the episodes multiple times because there is a lot of content condensed into a short amount of time. Over the next month, we will be exploring a variety of blockchain-based technologies. Some interviews will be high-level conversations that assume only a familiarity with cryptocurrencies. Some of them will be deeply technical and assume a strong understanding of Bitcoin and Ethereum. And some episodes, like today’s episode, will be aimed at the developer who is in the process of “going down the rabbit hole.” If you are looking for an internship, apply to the Software Engineering Daily internship, at softwaredaily.com/jobs. And if you are looking to recruit engineers, you can post jobs for your company there as well–it’s completely free to post jobs and to apply. We are hoping to find interns to contribute to the Software Daily open source project–and if you want to see what we are building, go to SoftwareDaily.com or check out our apps in the iOS or Android app store. They have all 650 of our episodes, with recommendations, related links, discussions, and more. The post Blockchain Scalability with Peter Ullrich appeared first on Software Engineering Daily.
