Java streams have been around since Java 8¹. Java streams have been extensively covered by tutorials, and documentations ²³⁴ and are heavily used in the wild⁵. This blog post exposes why java streams are so important for the java ecosystem.

The main point developed is that, compared to imperative for and if, Java streams produce “better” code at very little cost.

J’ai eu la chance d’enseigner¹ la programmation lors de la session d’automne 2024 au cégep Ahuntsic. L’expérience a été extraordinaire et je souhaite continuer. Comme souvent dans la vie, j’ai été surpris à bien des égards et j’aimerais partager mon expérience.

Mon curriculum vitae

D’abord, un peu de contexte à propos de moi. Bien que ça fait à peu près 15 ans que je programme professionnellement, je n’ai jamais étudié l’informatique. J’ai étudié les mathématiques où j’ai reçu un seul cours de programmation². En plus, je n’ai jamais été un étudiant très studieux.

In recent years, Java has introduced an impressive number of features. The development of Java has historically been relatively slow; it took about 2.5 years to go from Java 7 to Java 8, then 3.5 years to reach Java 9. But since Java 11, there has been a new Java release every 6 months, and these days LTS¹ versions are released every two years.

Background

I have never learned C# for two main reasons. First, as C# is a direct competitor to java, I have always favoured to use a technology I already master over a new technology. Second, I am a member of the Microsoft Haters Social Club; for almost theological reasons, I avoid anything that is remotly close to the MS world. Consequently, C# was label “I know it exists” by my brain for many years.

Introduction

In recent years, we have seen several game-changing software such as duckdb, web assembly and unison just to name a few. To this list, we can now add typst.

Typst is a modern, markdown-inspired, typesetting system that aims to be as powerful as LaTeX. Typst takes as input source code to output a pdf.

Nix flakes allow to include system dependencies from software that are not published on the nix packages repository but that are themselves flakes. This post will explain how to achieve this.

Context

We would like to create a document using the new markup language named typst. Typst presents itself as a markdown like language that produces pdf; moreover, typst promise to be as powerful as latex.
