My job requires me to speak at conferences. Despite the current situation, this hasn’t changed much. At the time of this writing, I submitted 439 different proposals to 215 unique conferences in 2020. I already wrote some advice for junior conference speakers. As a follow-up, I’d like to offer my view on the organization of conferences, from my speaker’s point-of-view. While the online and the on-site experiences are quite different, most of my feedback applies to both. DO s

Containerizing an application based on a 'scripting' language is straightforward. Add the sources, download the dependencies, and you’re good to go. One could say they are WYSIWYR. With compiled languages in general, and Java in particular, things are a bit different. In this post, I’d like to list some alternatives to achieve that.

When I started my career, books with titles such as 'Teach Yourself C in 21 Days', and 'Learn Java in 7 Days' were pretty popular. I was impressed that people could read such books. I never thought I could learn a new language in such a small amount of time myself. Time has passed. I’ve come to realize that I’m not alone in that case. Those books just happen to stretch the definition of learning a new programming language - and I’m being polite. In this post, I’d like to d

When I started my career, XML was ubiquitous. The meta-information in a Java JAR file - the manifest - follows a proprietary format. But Java EE designers built it from the ground up on XML: meta-information of all artifacts is in XML format e.g. web.xml, ejb-jar.xml, application.xml, etc. Java EE is one example I experienced personally. But XML was everywhere in the enterprise world at the time. Its prevalence manifested itself in two areas: configuration and data transfer. Ever since then,

In the previous post, we had a look on how to write a Kotlin script to automatically write a README that dynamically aggregates various data sources. In this follow-up post, we will describe how to run this script through the use of GitHub Actions. Yet another Continuous Integration tool It has been some time since Hudson, now known as Jenkins, was the leading (only?) Continuous Integration server available on the market. The last years has seen an precambrian explosion of alternatives: Atlas

Recently, GitHub allowed users to customize the appearance of their profile page. This is different from GitHub Pages: it allows to add extra content to one’s GitHub profile. Since that feature is available, a lot of developers have decided to customize their page. I think this is fun, so I also wanted to do the same, in my own way. I wanted to describe it, so fellow developers can take inspiration. Since the whole process is a bit long, I’ve split this post in two parts. This par

Not long ago, I came upon a LinkedIn post. It’s in French, but the theme is about sharing risk between the customer and the contractor in software development projects. To sum it up, the author is advocating for the Agile way: fixed-price contracting puts risk on the shoulders of the contractor, while time-and-material gives responsibility to the customer. Some commenters showed surprised that we, software developers, are not able to precisely assess risks by ourselves. They compare softw

I like GitLab a lot. Yet, there’s no denying that GitHub has become the de facto standard to host Open Source projects. With GitHub Actions, it’s now possible to implement entire Continuous Integration pipelines without leaving GitHub. In this post, I’d like to highlight how to release Maven artifacts using GitHub Actions. Maven prerequisites Before creating the CI pipeline - and running it, it’s necessary to configure the underlying Maven project. A quick Maven pr

A couple of months ago, I wanted to design a custom logo. The goal was to create 4 different variations for a single logo: horizontal, vertical, 'condensed', and square. All have to display the same bevel-like effect. I’m a developer, and not a web designer For this reason, I chose to use an existing point-and-click web application to create a SVG. It did the job. But I’m curious, and checked the generated XML: I was disappointed. This post aims to describe the lessons learned wit
