The Microwave With Feature Creep

Hi,

My microwave was broken.

So: I need a new one.

However, I have a little quirk when it comes to buying anything that’s not perishable. I want to avoid making a bad purchase. I’d rather spend more money once than have to buy a new one in two years.

Here, I have to be careful not to fall down a rabbit hole. I can spend hours reading reviews.

But what do I even want to compare?

What Sound Does Your Microwave?

Hi,

Do you know the feeling? You turn on a device that you use over and over again. For years. You recognize the sound it makes.

The rhythmic “whoosh whoosh whoosh”, when you start the dishwasher.

Or the familiar “click” when the oven turns on.

Your signal: everything’s working. Carry on!

But what if it suddenly sounds different?

It no longer meets your expectations?

That’s exactly what happened to me with my microwave.

Spring MVC: How to Use a Custom Converter for Type Safety in Controllers

Are your controllers constantly filled with primitives? In ArticleController, the first line of every method is: articleRepository.findById(articleId). We keep making the same conversions. I hardly observe as many primitives in any other layer as in the API layer. This leads to much boilerplate. The code becomes harder to test. And it’s harder to read. Yet we know how much easier it is when we work with type safety. In this article, I will show you how to use the Converter Interface to automatically convert your primitives into the correct type.

The Fifth Ideal: Customer Focus

Hi,

“The VPN should not be operated by you [Sysadmins].”

After this sentence, I saw startled faces.

It slipped out of me. During the weekly Jour Fixe between the developers and admins.

It came to the question of what our priorities are.

It hit a nerve.

Probably not because the participants are emotionally attached to the VPN.

Probably not because the statement is wrong.

No - it’s more likely because it’s so unconventional for the team.
