  • Summary

  • Podcast for developers, testers, SREs... and their managers. I explain complex and convoluted technologies in a clear way, avoiding buzzwords and hype. Never longer than 4 minutes and 16 seconds. Because software development does not require hours of lectures, dev advocates' slide decks and hand waving. For those of you, who want to combat FOMO, while brushing your teeth. 256 seconds is plenty of time. If I can't explain something within this time frame, it's either too complex, or I don't understand it myself. By Tomasz Nurkiewicz. Java Champion, CTO, trainer, O'Reilly author, blogger

    #97: Ruby: help every programmer to be productive and to be happy
    Feb 13 2023

    Yukihiro Matsumoto, the creator of Ruby programming language, famously said: “I hope to see Ruby help every programmer in the world to be productive, and to enjoy programming, and to be happy.” Honestly, not many programming languages were built with developer’s happines in mind. And to be honest, Ruby is a joy to work with. It’s fairly easy to learn, easy to read, yet, very powerful. Also, with the appearance of Ruby on Rails, it became insanely productive. But first things first.

    #96: Border Gateway Protocol: the duct tape that makes the Internet work
    Feb 6 2023

    Border Gateway Protocol, BGP for short, is probably the most important protocols you might have never heard of. Well, you did at least once, in October 2021. When Facebook, WhatsApp, Instagram and Messenger all went down because of BGP misconfiguration. Or that one day back in 2008 when all YouTube traffic was accidentally routed to Pakistan. Because of BGP… misconfiguration. So what’s the big deal with BGP? First we must understand how the Internet works.

    #95: SQLite: the most ubiquitus database on the planet. And beyond!
    Jan 23 2023

    SQLite is by far the most common SQL database ever deployed. Are you lsitening to this on iPhone or Android device? It runs SQLite. Or maybe through a web browser? Chrome, Safari, Firefox, Opera and Android Browser all use SQLite underneath. Are you running MacOS or Windows? It’s built-in. Most Linux distributions have it as well. “But I’m listening to your podcast while driving a car”, you say. Well, most automotive systems use SQLite internally. If you happen to listen to my podcast while coding in PHP or Python, they include SQLite out-of-the box. Oh, and it’s the default choice for Ruby on Rails as well. I’m pretty sure SQLite is used somewhere on the International Space Station and it maybe even landed on other planets? So, what makes this unsung hero so popular to run at least one trillion databases worldwide?
