@JackCarrUSA Sir, I just finished reading your book True Believer :) Loved it! Really curious to see how you’ll bring the story to the screen in The Terminal List Season 2. Btw, I’m starting your next book, Savage Son :) Wishing you all the best!

Spent a few days exploring LLM-as-a-Judge. Built a short RAG demo (Spring Boot + Spring AI + OpenAI + pgvector) that catches hallucinations before they reach the user.https://t.co/KEjS5GVAEq #RAG #LLM #AI @springboot

Rewatched @VadimBriliantov’s #Koog talk from @spring_io 2026 and really enjoyed it – so I had to give it a try myself 🔥

Here’s my demo of building an AIAgent with Koog + Spring AI + Spring Boot:

Recently I came across the #BlazePersistence framework from @Blazebit by @c_beikov . What caught my eye: Entity Views - a clean way to define type-safe projections on the of your JPA entities. See my demo with @springboot 4 and @Hibernate 7 at https://t.co/M1Qsw2XfMr

During XMas I was checking howto create @GraphQL @springboot clients with using @netflix #DGS and @springframework check my samples at https://t.co/oNVHa1DmHw

[Tomáš Klouček @TomasK79]

I was testing recently @GraphQL federation powered by @nestframework gateway and @springboot @springframework microservices using briliant #DGS framework provided by @netflix checkout my demo: https://t.co/ZwfP6dlXOV

Main topics of this years @Devoxx were terms #AI, #LLM, RAG etc...To my colleagues last week I was presenting sample of how to force the LLM to do the fallback from RAG context to his LLM pre-trained data when asking questions...@springboot @SpringTip at: https://t.co/Q6F1ZvTC8o

@1ovthafew @Hibernate @springboot No problem at all. No discomfort. That compile time code generation is a great feature. I worked recently on the large monolith with spring data where hot-reload was not always possible when having typo in query. Jakarta data approach helps a lot.

[Tomáš Klouček @TomasK79]

For my colleagues I prepared short demo of @hibernate 7 data repositories with @springboot 3 https://t.co/7JVXl3OEuc as intro to what has been presented at #Devoxx ...Play with it if you want...Really like the compile time code generation for repositories..👍

[Tomáš Klouček @TomasK79]

Gavin King said on @Devoxx that using repository method names as query generator is awful. He just ruined my world :) I'm kidding..New Hibernate 7 Data Repositories looks great https://t.co/AhEUL23mMu and this was still the best talk for me on Devoxx. Thank you @1ovthafew

[Tomáš Klouček @TomasK79]

I am on @Devoxx in Anwerp right now, a lot of cool stuff to see here...Like relatively new framework WebForJ...Worth to check it out: https://t.co/TcdR8OzlDn

@VividProwess Not yet, but it's very high on my travel list :)

[Tomáš Klouček @TomasK79]

I take @golang as next gen backend language, during learning I just cracked in GO this Kata: https://t.co/opDKtDKn5C Anyway switching from my job's #Java to #Go is always painful because of the Go's "type on the right" syntax :(

[Tomáš Klouček @TomasK79]

Filling xmas time with reading articles :), I just read nice comparison of most popular db libraries in @golang https://t.co/QFya96bnTi

[Tomáš Klouček @TomasK79]

I'm now reading book "Go in Action". For us Java devs virtual threads are game changer, but very similar concept has been introduced in @golang almost before a decade with go routines. Design of Golang never cease to amaze me.

Just finished third season of Fauda. Best TV Show I have seen this year. I can highly recommend. @FaudaOfficial 🇮🇱♥️

Strongest line from this year's @GeeCON "By 2025, 70% of newly developed applications will use low-code or no-code technology"..IMO this is unreal wish of companies producing low code platforms, because low/no-code systems becomes quickly obsolete, but it makes you thinking..:\

@davefarley77 Locally it works....

[Tomáš Klouček @TomasK79]

@alina_yurenko @spring_io I was there at 2022...Couldn't attend this year :( ...Enjoy and get one sangria :)

[Tomáš Klouček @TomasK79]

When building REST API with @FlutterDev then next to Dio package it is good to use #Retrofit package which is very similar to @springframework #FEIGN....Check my last repository: https://t.co/x0zeZujaz9
