Software Engineering Daily

Ethereum is a system for running decentralized smart contracts. In the current implementation of Ethereum, every smart contract gets deployed to every full node. Whenever a user wants to call a smart contract, that smart contract gets executed on each full node–across the entire network.

The current model for smart contract execution needs to be made more scalable. In today’s episode, Christian Reitwiessner joins the show to describe Plasma–a system for scaling smart contracts. Christian is a developer who has worked extensively on Solidity, the most popular smart contract programming language in Ethereum.

For the last month, we have focused on blockchain related topics, and we will soon be shifting to other subjects. Some of the listeners have not enjoyed the blockchain focus, other people have loved it–for everyone listening, we would love for you to fill out our listener survey at softwareengineeringdaily.com/survey. This will help us decide what other content to focus on.

Of course–you can also send me an email at any time, jeff@softwaredaily.com. And join our Slack at softwareengineeringdaily.com/slack. And if you are completely sick of cryptocurrencies, check out our back catalog of episodes at softwaredaily.com, or by downloading our apps, which have all of our episodes including our Greatest Hits, which is a curated set of the most popular shows. The apps will soon have offline downloads and bookmarking.

ConsenSys has hundreds of web3 developers that are building decentralized applications, focusing on world-changing ideas like creating a system for self-sovereign identity, managing supply chains, developing a more efficient electricity provider and much more. ConsenSys is actively hiring talented software developers to help build the decentralized web. Learn more about Consensys projects and open source jobs at consensys.net/sedaily.

GoCD is a continuous delivery tool created by ThoughtWorks. GoCD agents use Kubernetes to scale as needed. Check out gocd.org/sedaily and learn about how you can get started. GoCD was built with the learnings of the ThoughtWorks engineering team, who have talked about building the product in previous episodes of Software Engineering Daily. It’s great to see the continued progress on GoCD with the new Kubernetes integrations–and you can check it out for yourself at gocd.org/sedaily.

LiveRamp is one of the fastest growing companies in data connectivity in the Bay Area, and they are looking for senior level talent to join their team.

LiveRamp members value entrepreneurship, humility, and constant personal growth. If this sounds like a fit for you, check out softwareengineeringdaily.com/liveramp.

There’s no need to reinvent the wheel when it comes to making your app “realtime.” PubNub makes it simple, enabling you to build immersive and interactive experiences on the web, on mobile phones, embedded into hardware, and any other device connected to the Internet. With powerful APIs, and a robust global infrastructure, you can stream geolocation data, send chat messages, turn on your sprinklers, or rock your baby’s crib when they start crying (PubNub literally powers IoT cribs). 70 SDKs for web, mobile, IoT, and more means you can start streaming data in realtime without a ton of compatibility headaches, and no need to build your own SDKs from scratch. Go to PubNub.com/sedaily to get started. They offer a generous sandbox tier that’s free forever (until your app takes off).
