My new project in adesso Turkey uses Kotlin in some services. It is the first time that I am using Kotlin and not gonna lie, I liked it so far. It gives you the feeling that this language is modern and has nice approaches to some problems. And that got me thinking about these solutions, why Kotlin decided that and such. And interesting enough that Kotlin doesn’t use some features Java has eg. checked exceptions. So I decided to break down these features to understand the general mindset behind Kotlin (and also Java)

• Both functional and OOP

One of the biggest advantages of Kotlin is that it can be used as both functional and object oriented. While that might raise a question to Java developers in that they are used to build a hierarchy no matter what they are writing, I think this flexible approach is better even for OOP approached apps.

In it’s second year, ChatGPT published its 5th version of its GPT algorithm with GPT-4o and every version puts something into its predecessor. Even Gordon Moore didn’t estimate this kind of speed in that even this article will be outdated just after several months.

Thinking and making assumptions about what kind of future awaits us is not easy obviously but I want to point out my concerns about my job (some other jobs too) to proactively decide what we can do to adapt it.

Custom / Personal GPTs

ChatGPT has already a market, if you will, where people customizes the algorithm for a certain purpose. It’s not just ChatGPT as you already know, from Windows, to Adobe, hack even Notepad will get an AI assistant. It is debatable how efficient they work at the moment but that doesn’t mean it will be more efficient in the future. It will be. The more it gets customized and trained in that way, the …
