Spring Boot provides a good set of starters for the popular open source frameworks used in modern Spring applications. However, it is not limited to that, and we are not at the mercy of the Spring Boot gods. We can create our own starters.
Uploading a file with Spring MVC is pretty easy, and it gets even easier when running in Spring Boot. However, it's one of the tasks a developer does once in a while and therefore is pretty easy to forget. The page is a reminder for all of us.
I build several desktop applications using PySide. It works like a charm on Windows. However, I found a nasty bug in the Mac version which I could not reproduce on my local machine. This one drove me nuts. It was hard to analyze, I own just one Mac and do not have access to another machine. Luckily, with the help of some very long googling (guessing symptoms) and the help of a user of one of my applications, I could fix the issue. As a reminder for myself and help for you, I document it.
While researching alternatives to publishing books for programming related topics, I noticed that video courses get more and more common as the medium. I started wondering if works for coding related topics.

The Spring Boot Actuators are a big helper and time saver when you bring your application into production. They expose different types of information, like health, metrics, dump, info, etc. out of the box and you can even expose your informations via well-defined interfaces.
When you are starting a new Spring Boot application today, you will probably want to use Java 8. However, it still can be tricky with certain frameworks when using new features like the Date and Time API (known as JSR-310).
Sometimes you still need to return XML in your Rest API for various reasons. When you build your API with Spring Boot and Spring MVC, it is a simple, easy task.
It all started a few years ago that I felt stuck in my career as a software developer. For years I've been following the typical way of learning and dabbling with new technologies, mainly in my spare time or on occasion on the day job. Tech was fun, and I always love learning new things. However, when I felt stuck I realized that my previous ways did bring me so far, but they do not take me any further. It doesn't matter if you're an employee, freelancer or owning a small agency. At some point, there's a glass ceiling for money and the kind of work you do.
I haven't done any game development for a long time. However, I still stumble regularly upon great resources for game graphics; free and paid. So, I decided to curate a collection here on my blog.

Paddle is a payment processor for selling things online and specially targeting software developer and their needs. They even support trial version and license activating through their SDK. Unfortunately, last year as I started to use them for my eBook Writing Software Moopato the Windows SDK was dotnet only and not suitable for a python application (They now offer a non dotnet version too). But there was another solution I am going to show you now.
