Software creation

We all partake in software creation, as developers, architects, analysts… This category covers topics for all these people and probably more, from coding tools and best practices to architecture and management recommendations.

A few months back, a new guy joined our team and the Java world after a few years of being a .NET programmer. He had many reactions like, “What, you need to write that yourself in Java? In .NET, the compiler does it for you!”

It’s true that, in Java, the language and conventions drive you to write a non-negligible amount of low-value code. But don’t fear! Lombok aims at simplifying that task for you.

I like regular expressions, very much. A bit too much, probably, but I’m aware of that and I don’t use them that much.

That doesn’t prevent me from trying some funny patterns, and I’ll be sharing some of them here for the sake of learning.

When designing a website, we’re often tempted to use custom webfonts to make it stand out. Yet, the French collective for a responsible design of digital services provides one simple rule in their referential for web ecodesign:

Use standard typefaces

translated from Référentiel d'écoconception web (FR), Collectif Conception responsable de service numérique

Let’s have a look at what’s behind this rule.

What You Should Know About Logging

A few weeks back, I reviewed code from a young developer. It was impressive work for a topic he didn’t know beforehand, except on one aspect: every output used System.out.println(). That’s understandable: that’s how Java developers learn to code, just like Python developers do their first tests with print. But that’s not something that’ll be handy for a live application.

You may or may not have noticed it, but I try to avoid the terms “developer,” “coder” and “programming” on Keyboard Playing, except maybe when I’m focusing on the activity of writing code. There’s a reason to it: in our field, it’s common to use these words to describe a variety of jobs. Actually, about anyone who writes or edits code may be called a developer.

Sometimes, I don’t understand something, so I search the answer and sharing it is natural. Sometimes, I don’t think sharing it will be any use, until I realize that some people, even in my team, struggle with the same thing. This post is in the second category.

If you use NPM regularly, you must have noticed it adds tildes (~) or carets (^) in front of your dependencies’ version number. You may also have noticed it creates a package-lock.json file. If you don’t know what any of these are, this post will shed some light.

When you develop a Java program that accesses a database, you’re likely to need a JDBC driver. When that database is an Oracle product, you keep that O for OJDBC.

For years, I just used the version an architect had selected. Then, I became the architect and I had to understand which version to choose. It’s not that complicated, just not really well explained. Let me try to contribute…

We Are Creating the Future

To conclude this series about sustainable IT, I wanted to write a bit about some impacts of software creation that we rarely think about. We’ve all seen movies where a mad scientist creates something that they think is awesome until it escapes their control and threatens life as we know it.

Everybody’s a mad scientist, and life is their lab. We’re all trying to experiment to find a way to live, to solve problems, to fend off madness and chaos. David Cronenberg

That’s especially true about us software creators: we innovate, create new technologies for thousands or millions of people. If we’re not careful about those creations, they may transform the whole society, though not necessarily in the way we assumed they would.
