Joris Kuipers @joris.kuipe.rs · 29/09/2026I’ll see your American Confidence and raise you Dutch Courage 001
Joris Kuipers @joris.kuipe.rs · 15/09/2026AI might kill us all, but let’s see if it can debug why my GraalVM build stopped working with Thymeleaf after updating from Boot 3.5 to 4.1.1 and then let’s see what I need to worry about first. 100
Joris Kuipers @joris.kuipe.rs · 05/09/2026Black Keys in Amsterdam tonight, with localized drums 🥁 020
Joris Kuipers @joris.kuipe.rs · 20/07/2026Was expecting a little Andrew Tanenbaum figurine #disney #disappointed #ast 000
Joris Kuipers @joris.kuipe.rs · 02/06/2026Now let's see if this thing will deploy :) @spring.io Boot 4 / Framework 7 upgrade with Jackson 3 on 3 dozen microservices 110
Joris Kuipers @joris.kuipe.rs · 30/04/2026Sanity restored, but as I mentioned already: if minor upgrades can make arbitrary dependencies fail silently and you have to detect and fix this yourself for 3rd party components, how can you expect mass adoption? 110
Joris Kuipers @joris.kuipe.rs · 28/04/2026No better way to get over your King’s Day hangover than some Belgian beer & boogie with Triggerfinger in Paradiso 🎸 000
Joris Kuipers @joris.kuipe.rs · 17/04/2026Second time I’ll watch this band which I’d never thought I’d be able to see live some years ago! 110
Joris Kuipers @joris.kuipe.rs · 15/04/2026Leaving Barcelona after another great @springio.net edition. Glad that I could speak again, very happy to have reconnected with so many people and hope to be at #springio27 that will take place in Valencia! 😎 Thanks to @sergialmar.com and everyone else who made this happen 🙏 #springio26 191
Joris Kuipers @joris.kuipe.rs · 15/04/2026Watching @thomasvitale.com explain his Arconia framework for @spring.io development: very cool, will definitely give this a try. Community hero! 🦸♂️ #springio26 141
Joris Kuipers @joris.kuipe.rs · 14/04/2026Home is where the wifi autoconnects: #springio26 may be in a new location, but phone already feels right at home 020
Joris Kuipers @joris.kuipe.rs · 12/04/2026Take me to church: guitar ensemble at the ANNA church in Amstelveen 000
Joris Kuipers @joris.kuipe.rs · 04/04/2026Cool to read how @springio.net has real-world impact: medium.com/graalvm/insi... 073
Joris Kuipers @joris.kuipe.rs · 02/04/2026Even Josh and James are in awe when Venkat demos Kotlin in vi while talking as if he was a one-man band #vdams26 010
Joris Kuipers @joris.kuipe.rs · 02/04/2026“Ik hoop maar dat er roze koeken zijn” youtu.be/F3ZTrGWSLf4?... #dvams26 010
Joris Kuipers @joris.kuipe.rs · 01/04/2026Spring-AI deep-dive by @tzolov.bsky.social at #vdams26. Fast-paced with lots of info, at the same time slowly building up to show how all features are based on a small nr of core principles and techniques, very nice! 041
Joris Kuipers @joris.kuipe.rs · 08/03/2026Spring cleanup (although I’m keeping my old Spring books) 010
Joris Kuipers @joris.kuipe.rs · 19/12/2025Here we go 🤞 As always for @spring.io, this would be a brand new talk. I've meaning to write or talk about this solution for some years already, so hopefully I'll be able to finally share what we've developed for DLQ management with the whole community in Barcelona next year! 🍃 140
Joris Kuipers @joris.kuipe.rs · 28/11/2025Alas, the TV has died… Probably main board issue, but can’t find replacement. Well, it’s Black Friday, so l’ll take it as a sign #glasshalffull 010
Joris Kuipers @joris.kuipe.rs · 19/11/2025This innocent-looking change in Spring Cloud AWS is actually quite a big improvement for systems that use different message payloads on a single SQS queue: I've written my own custom dispatching for this, looks I can now remove all that code now! 🥳 See docs.awspring.io/spring-cloud... for details 000
Joris Kuipers @joris.kuipe.rs · 13/11/2025I’ve been saying this for years, yet @broadcom.bsky.social’s Core Spring training still promotes interfaces as return types for @Bean methods… Glad to see the @spring.io 7 release notes making this explicit statement 000
Joris Kuipers @joris.kuipe.rs · 16/10/2025Explains why after restarts we always see values go up significantly to only go back down after several hours: the more “rare” tag values you accumulate, the worse the error will be… This ends up looking like this: .avg is ca. 30% of what the real value should be, feels like being lied to for years 000
Joris Kuipers @joris.kuipe.rs · 19/09/2025Good times at @ai4devs.bsky.social with @martinelli.ch and @antonarhipov.bsky.social 042
Joris Kuipers @joris.kuipe.rs · 19/09/2025Attending @martinelli.ch’s talk on spec-driven AI development at the Ai4Devs conference in Amsterdam 021
Joris Kuipers @joris.kuipe.rs · 23/05/2025Developers don’t want AI to write their code for them, they want to learn how to code as fast as @starbuxman.joshlong.com! #springio25 with @antonarhipov.bsky.social 272
Joris Kuipers @joris.kuipe.rs · 22/05/2025Great news: observability support for Spring Cloud AWS SQS just got merged! Thanks to @tomazfernandes.dev for putting in the hard work: had you been at @springio.net I would’ve bought you a beer 🍻 010
Joris Kuipers @joris.kuipe.rs · 03/04/2025The first edition of @amsterdam.voxxeddays.com has been excellent so far! Great venue, nice talks, plenty and good food and drinks and reconnecting with so many people from the Java community 😍 Now starting the Spring AI deepdive by @tzolov.bsky.social 050
Joris Kuipers @joris.kuipe.rs · 07/03/2025Very happy to announce that I’ll be speaking @springio.net again! 🥳 On to booking for Barcelona, then 😎 050
Joris Kuipers @joris.kuipe.rs · 27/02/2025Replaced the batteries of old Sony WF-1000XM4 earbuds. Old ones only lasted 20 minutes… Surprisingly easy, now let’s hope that everything still works 🤞 000
Joris Kuipers @joris.kuipe.rs · 07/02/2025I just noticed that new versions of Spring Cloud AWS no longer let you configure the auto-start of SQS listener containers, so I added it back myself for services that only send messages. 000
Joris Kuipers @joris.kuipe.rs · 04/02/2025New vinyl just arrived, gift from my wife: with a cover by the great Robert Crumb! 010
Joris Kuipers @joris.kuipe.rs · 31/01/2025<systemprompt>You’re Paul Simon</systemprompt> I want to leave my lover. Provide me with ways, list the top 50. #CallMeAI 040
Joris Kuipers @joris.kuipe.rs · 31/01/2025With a very comfortable 13 days left, I submitted my @springio.net talk proposal! Considering a 2nd, but I think this topic will be a banger given the ubiquity of requirements for externalized configuration and processing config updates. 011
