Ep #97 of #aroundITin256 #podcast: #Ruby: help every programmer to be productive and to be happy: https://nurkiewicz.com/2023/02/ruby.html

"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 happiness in mind. [...] Ruby is a joy to work with. It's fairly easy to learn, easy to read, yet, very powerful. Also, with the appearance of #RubyOnRails, it became insanely productive

Ep #96 of #aroundITin256 #podcast: Border Gateway Protocol: the duct tape that makes the Internet work: https://nurkiewicz.com/2023/02/bgp.html

"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 [...] So what's the big deal with BGP? First we must understand how the Internet works."

Ep #95 of #aroundITin256 #podcast: #SQLite: the most ubiquitous database on the planet. And beyond!: https://nurkiewicz.com/2023/01/sqlite.html

"Are you listening to this on #iPhone or #Android? 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 automotive systems use SQLite internally. If you to listen to my podcast while coding in #PHP or #Python, they include SQLite"

Ep #94 of #aroundITin256 #podcast: #Scala: language with academic background and huge industry adoption: https://nurkiewicz.com/2023/01/scala.html

"Scala is a programming language running on the #Java Virtual Machine. [...] The functional side of Scala supports higher-order (and higher-kinded) types. For those of you know what it means"

Ep #93 of #aroundITin256 #podcast: K-means clustering: machine learning algorithm to easily split observations into multiple buckets: https://nurkiewicz.com/2023/01/k-means.html

"K-means clustering is an algorithm for partitioning data into multiple, non-overlapping buckets. [...] To be honest, that's quite a simple task for humans. [...] However, this is not that straightforward once you can no longer rely on graphical representation. For instance, when your data points live 3-, 4- or 100-dimensional space"

Ep #92 of #aroundITin256 #podcast: #Clojure: a languages that will change the way you think about programming: https://nurkiewicz.com/92

Clojure is a dynamically, strongly typed programming language. It's a dialect of #Lisp running on the #Java Virtual Machine. Lisp is 6 decades old and has a really weird syntax. [...] In Clojure, you always put the operator (or any other function for that matter) in front. So simple addition becomes... `+ 1 2`

Ep #91 of #aroundITin256 podcast: Asynchronous communication: loose coupling in distributed systems: https://nurkiewicz.com/91

"There are two main ways to communicate between components in your distributed system: synchronous and asynchronous. Synchronous communication is like making a phone call. The system on the other side must be present and you actively wait for a response to your every question. Examples of this style include #REST, #SOAP and #GraphQL"

Ep #90 of #aroundITin256 #podcast: #Mastodon: next-generation, open source social network: https://nurkiewicz.com/90

"After many dramatic events around #Twitter lately, many people, including myself, began experimenting with Mastodon. Superficially it's an open-source clone of the former that anyone can deploy and host. However, once you look deeper, it's actually a completely different philosophy and architecture. Let's focus on how Mastodon federated network is built"
