Ops teams are pets, not cattle (ep. 556)
A common refrain you’ll hear these days is that servers should be scaled out, easy to replace, and interchangeable—cattle, not pets. But for the ops folks who run those servers the opposite is true. You can’t just throw any of them into an incident where they may not know the stack or system and expect everything to work out. Every operator has a set of skills that they’ve built up through research or experience, and teams should value them as such. They’re people, not pets, and certainly not cattle—you can’t just get a new one when you burn out your existing ones. On this episode of the podcast—sponsored by Chronosphere—we talk with Paige Cruz, Senior Developer Advocate at Chronosphere, about how teams can reduce the cognitive load on ops, the best ways to prepare for inevitable failures, and where the worst place to page Paige is. Episode notes:Chronosphere provides an observability platform for ops people, so naturally, the company has an interest in the happiness of those people. If you’re interested in the history of the pets vs. cattle concept , this covers it pretty well. Previously, we spoke with the CEO of Chronosphere about making incidents easier to manage. We’ve covered this topic on the blog before, and two articles came up during our conversation with Paige. You can connect with Paige on Twitter, where she has a pretty apropos handle.

From cryptography to consensus: Q&A with CTO David Schwartz on building blockchain apps
Right now, plenty of people are building businesses on social media platforms, on streaming platforms, and on market platforms that they don’t control. That platform can make the rules in any way they want and remove access at any time. That means founders are potentially one step away from losing their livelihood. The same goes for consumers buying from these platforms: if you lose access to your account, there goes all your purchases. As it turns out, you were licensing everything, not buying it. On this sponsored episode of the podcast, we talk with Ripple CTO David Schwartz about the promise that decentralized trust and distributed consensus has for software development — and for more transparency in ownership. Episode notes:Cross-border payments, while they might not be the sexiest app, are one of the best product-market fits for blockchains. Learn more about Ripple at their home page. Check out the documentation to learn more about building on the XRP Ledger. Congrats to Lifeboat badge winner, asmeurer, for their answer to What does `S` signify in SymPy?

From Smalltalk to smart contracts, reflecting on 50 years of programming
Smart contracts aren’t actually new. Computer scientist, legal scholar, and cryptographer Nick Szabo coined the term in 1994 (possibly earlier, depending on who you ask). Old problems seem to keep coming back. Bret Victor gave a talk in 2013 called “The Future of Programming,” where he talked about problems from 1973 that were still relevant. To learn more about the Agoric blockchain, check out their homepage. If you’d rather shape how the blockchain itself operates, much of Agoric’s code is open source.
