I've written an article about AI and the future of development. What things will change? What skills will become crucial? And what should we not be afraid of?

Recently, I switched from Golang to Java. Here is my perspective on the Dependency Inversion Principle in those languages.

I've written an article about #jooq and #hibernate. Specifically, JOOQ cannot replace Hibernate because these tools solve different problems.

@wimdeblauwe We use it in our project. Fine and convenient piece. Especially the fact that the library has Jackson module to store outbox records as JSON

[Semyon Kirekov @simon_kirekov]

I wrote a new article about creating custom methods in your REST API. What method should you use to send an email draft? Is it POST? Or maybe PATCH that changes the draft status? You will find the answer in my article ;)

@simas_ch Oh, I get it now 😅. MapStruct provides an interface and generates its implementation. Well, the presence of interface assumes multiple types of behaviour. But mostly there is only one way to map A to B. That makes this level of abstraction obsolete IMHO

[Semyon Kirekov @simon_kirekov]

@simas_ch Yeah, that’s what I meant ;)
I haven’t heard about ObjectMapper library. Is it an actual thing? When I try to google “Java ObjectMapper” I only get result about Jackson

[Semyon Kirekov @simon_kirekov]

@simas_ch Anyway, a Java record has to be transformed to JSON somehow. For instance, if you return it in controller method. If you use Spring Boot, it uses ObjectMapper underneath by default

[Semyon Kirekov @simon_kirekov]

@simas_ch But how do you transform an entity or a JOOQ projection to JSON? For example, consider a regular GET endpoint “get something by id”. I need to return application/json format for a client.

[Semyon Kirekov @simon_kirekov]

@simas_ch Totally agree. Claiming that Hibernate is bad is the same as complaining that English is a bad language because one doesn’t know it

[Semyon Kirekov @simon_kirekov]

Just got my first iPhone. I have to admit that it’s much more convenient in comparison to Android. Though I’ve been Samsung user for many years

[Semyon Kirekov @simon_kirekov]

Thank you for sharing my piece
