Garbage collection ( GC ) is an essential process
in any programming language that manages memory for the programmer. In Ruby (this article is about
the MRI ), the garbage collector plays a crucial role in ensuring efficient
memory usage and preventing memory leaks. 
 The Heap and the Stack 
 Memory in a Ruby program is divided into two main regions: 
 
 The Heap : This…
One of the most fundamental principles of Ruby is that everything in the language is an object. This object-oriented allows developers to think in terms of objects and their interactions rather than just functions and procedures. 
 In Ruby, every piece of data, whether it’s a number, string, array, or even a class itself, is treated as an object. This means that all these entities can have…
Ruby is a dynamic, interpreted , open-source programming language known for its simplicity, productivity, and its “human-readable” syntax. Ruby is often used in web development, particularly with the Ruby on Rails framework. It supports object-oriented, functional, and imperative programming paradigms. 
 The most known and used Ruby Virtual Machine is the M atz R uby I nterpreter (aka CRuby),…
Kube & the CKA 
 
 Kube , k8s or Kubernetes is the industry leader
when you need to orchestrate some containers at scale. The containers war is
over : Swarm, Mesos and all other alternatives are dead (except
 Nomad under some circonstances). 
 The Certified Kubernetes Administror (CKA) is a certification delivered by
the Cloud Native Coputing Fundation (CNCF) and the…
From netcl to iwd 📡 
 ArchLinux is installed on my laptop (an XPS 15) since I got it from my job in
2017 1 . 3 years ago, the cli tool distributed within the distribution was
 netctl . It’s an in-house ArchLinux
project allowing users to manage
networking. Overall, the tool does everything I need to get a
network connection up and running the way I need it. One of…
Elixir, the path to functional programming ⚗️ 
 With my Rust rediscovery 
a lot of functional programming concepts became less obscure. In order to
go deeper into this paradigm I chose Elixir a powerful general purpose, functional
programming language, compiled and executed inside the Erlang virtual
machine ( BEAM ). 
 But why Elixir , if Erlang exists ? Because : 
…
Rust, the (re)discovery 🗺️ 
 Back to 2014 , the year I wrote my first Rust program ! Wow, that was
even before version 1.0 ! 
 At my school, it was all about C , and 10 years of C is quite boring
(because, yes, I started programming way before my engineering school). I
wanted some fresh air, and even if I really liked Python back to that time,
i’m more into…
To infinity… and beyond! 
 DevOps, IaC, AGILE, SCRUM, Containers, SysOps, CI/CD, microservices, serverless, FAAS
 
 Yes, it’s a buzzwords shitstorm but all of these concepts summarize how
 software development and deployment evolves. Do i think that sysadmins
time is over ? No . 
 But time as come, we , as sysadmins, have to adapt to this moving
industry.…
Hi ! 
 New year, new blog. 
 A quick post to introduce me and this site : I’m Wilfried , a junior SRE. 
 I will used this plateform to share experiences and opinions about dev and ops worlds. 
 Feedback is and will be always welcome, if you want to contact me, see the footer below. 
 Have a nice read ! 
 Bye !
