Platform adoption can fail even when the tech is fine. Mandates create “usage,” then teams build workarounds to keep shipping. You pay the platform cost and you still inherit the extra tech debt. Good breakdown here on what changes the outcome: platformengineering.com/features/why...

We’re live now with @dashaun.com and @cat-edelveis.bsky.social. Real talk on container security from the Devoxx 2025 survey. Join here: www.youtube.com/watch?v=Sqmx...

Your container security strategy might be setting you up for failure and you won't know until it matters. ⚡ Live TODAY 09:30 ET: @dashaun.com & @cat-edelveis.bsky.social break down the 2025 State of Container Security survey from Devoxx: www.youtube.com/watch?v=Sqmx...

Spring Data MongoDB takes the best of MongoDB and Spring Data. @cat-edelveis.bsky.social covers indexing, projections, custom queries, and aggregation pipelines. Real queries, actual data volumes, analytics. Practical patterns for production use: youtu.be/LCHMQk_uAv4

Most Java security incidents are predictable engineering debt: vulnerable deps, weak boundaries, and no visibility when things break. We wrote a practical #Java app security checklist that covers code, runtime, and containers: bell-sw.com/blog/a-guide...

In the upcoming #Java26, lazy constants get their second preview (JEP 526). java.lang.LazyConstant lets the app initialize them on demand with at-most-once semantics even under concurrency. Once initialized, the JVM can treat the value as a true constant and apply constant folding.👇

Onboarding a new team taking weeks instead of hours is usually a symptom, not the problem itself. This article explains how ad-hoc DevOps practices stop working at scale, and where platform engineering really helps: platformengineering.com/social-faceb...

🧵 Thread: CVEs in container images don’t “end” just because you cleaned up an image once. If you run containers in prod, save this for later.

People know rules, production does its own thing. Our Devoxx 2025 survey of 427 engineers maps the gap between “security is a priority” and day-to-day reality: what’s in base images, how often teams update them, and where security work stalls on time. Get the full report: bell-sw.com/state-of-con...

New on our channel: sizing JDBC connection pools for real production load. Many outages aren’t due to “slow DB”, it's pool exhaustion: ms queries, seconds waiting for a connection. @cat-edelveis.bsky.social covers sizing, timeouts, and when a proxy approach helps: youtu.be/0iHlROKQJcw

JDBC connection pools don’t always survive microservices. @cat-edelveis.bsky.social and Rogerio Robetti break down why pools fail, what it looks like in production, and how to solve the issue. 📅 Jan 29 · 6:00 PM CET 🔔 www.youtube.com/live/j13zs_L...

Mandating platform adoption is usually a sign something went wrong earlier. This article looks at which metrics show whether a platform helps teams move faster, with insights on DORA metrics, cognitive load, why voluntary adoption matters more than dashboards: platformengineering.com/features/the...

Liberica JDK CPU/PSU updates are out for 6, 7, 8, 11, 17, 21, and 25. The release contains 1217 fixes and backports overall. BellSoft participated in eliminating 21 issues in all releases. Details: bell-sw.com/blog/liberic... Download: bell-sw.com/pages/downlo...

JPA, JDBC, Hibernate, jOOQ, Blaze Persistence: where do they belong in the DB access stack? This video untangles the concepts and makes the “when to use what” decision easier. By @cat-edelveis.bsky.social: youtu.be/fiThkd__HEU

Update: the Spring Boot + Vaadin webinar on Java container images is now happening tomorrow (Jan 20), same time. @cat-edelveis.bsky.social and Miikka Andersson will cover layering, image size, startup time, and practical hardening. 🕒 18:00 CET / 12 PM ET / 9 AM PT 🔔 pages.vaadin.com/creating-a-p...

In the upcoming #Java26, the Vector API stays incubated for the 11th round (JEP 529). It lets you express SIMD-style loops with FloatVector/IntVector so HotSpot can reliably map them to AVX/NEON instructions at runtime, often beating scalar code.👇

A conversation on agentic AI that stays grounded. Embabel takes a JVM-native approach with structure, planning, and strong typing, instead of piling prompts on top of each other: www.youtube.com/live/bHjSjvc...

🧵 #Java 26 has entered Rampdown Phase One, which means the feature set is frozen. GA is scheduled for March 17, 2026. Here’s the short, practical tour: what’s new, and why you might care. Bookmark for later, especially if a #Java26 upgrade is on your roadmap. 👀

Hardened container images are becoming the default. The harder part now is choosing what actually fits your workload. IProgrammer explains how different hardened image approaches make sense depending on what you’re running: www.i-programmer.info/news/240-dev...

Hibernate isn’t just “good” or “bad”, it depends on where you use it. In our new video, @cat-edelveis.bsky.social breaks down when ORM helps, when SQL is a better choice, and how hybrid approaches work in real production code: youtu.be/J12vewxnNM8

Building #Java container images always comes down to trade-offs. On Jan 15, @cat-edelveis.bsky.social and Miikka Andersson will explore approaches to layering, size reduction, and startup time reduction using a Spring Boot + Vaadin app. 🕒 18:00 CET 🔔 pages.vaadin.com/creating-a-p...

In the upcoming #Java26, structured concurrency reaches its sixth preview (JEP 525). StructuredTaskScope lets you fork related subtasks, join once, and get automatic cancellation and error propagation. 👇

Happy Holidays from BellSoft! Wishing you a calm week, reliable builds, and time to unplug (at least for a bit). Thank you for being with us.

Spring Boot 4 raised a lot of practical questions, and this conversation is a good place to hear them discussed out loud. Catherine Edelveis and Josh Long talk through what actually changed and how it feels in day-to-day work, beyond what’s in the release notes: www.youtube.com/watch?v=c8q8...

#Java26 JEPs are easier to digest when someone walks them end-to-end. This video goes through all novelties and points out what changes in day-to-day #Java work (not just the headlines): youtu.be/wtTdWkosCIc

In the upcoming #Java26, pattern matching with primitive types gets improved (JEP 530) bringing enhanced definition of unconditional exactness and tighter dominance checks in switch. Enable preview in your Java 26 build and see how violated dominance yields a compile-time error 👇

We’re live! @cat-edelveis.bsky.social and Rod Johnson are talking about Embabel and what agentic AI on the JVM looks like when you treat it as real software, not just prompts. Join here: www.youtube.com/live/bHjSjvc...

Update on the Embabel stream: new day, new time. Still a conversation about JVM-native AI agents and Embabel, happening tomorrow at 19:30 AEDT / 10:30 CET. 🔔 www.youtube.com/live/bHjSjvc...

If agentic AI on the JVM is on your radar, tune in tomorrow at 13:00 AET. Catherine is live with Rod Johnson to talk about Embabel and what changes when you build agents with structure, planning, and strong typing instead of stitching prompts together. 🔔 www.youtube.com/live/bHjSjvc...

Can AI really replace developers, or just generate impressive-looking mess? @asm0dey.site walks through vibe coding a full project, MCP servers, and where AI actually helps in real workflows. Watch now: youtu.be/TzS1drWRRMM

Starting soon! @cat-edelveis.bsky.social and @starbuxman.joshlong.com will be live discussing Spring Boot 4 and how this release shapes the next chapter of the Spring ecosystem. Join here: www.youtube.com/watch?v=c8q8...

In upcoming #Java26, java.net.http.HttpClient will support HTTP/3 (JEP 517). The default stays HTTP/2, but you can set HTTP/3 in the client or in the request, and the request will transparently fall back to HTTP/2/HTTP/1.1 if HTTP/3 isn’t available. 👇

Spring Boot 4 was recently released, and it’s a meaningful update for anyone building with Spring. On December 12 at 12 PM PST, @cat-edelveis.bsky.social will join @starbuxman.joshlong.com to explore what this milestone means and where Spring is heading next. 🔔 www.youtube.com/watch?v=c8q8...

📚 @infoq.com covers BellSoft Hardened Images, a hardened OS + runtime that shrinks the attack surface of #Java containers. The article shows what goes into base images, why CVE counts climb up, and how it compares to Alpine, distroless and other minimal bases devs use: www.infoq.com/news/2025/12...

If your CVE backlog feels like a second job, this is relevant. In a new @itopstimes.bsky.social article, Alex Belokrylov, CEO of BellSoft, argues for hardened, minimal platforms where most vulnerabilities are handled upstream instead of one ticket at a time: itopstimes.com/cybersecurit...

Hardened images make container security a lot more predictable. @cat-edelveis.bsky.social shows how minimalistic base and clear provenance work in real setups, including a #Java workflow with Liberica, multi-stage builds, digests, and Cosign: youtu.be/Co164aVGCjw

New video: @asm0dey.site shows how to build a RAG setup in Spring AI that answers based on your docs instead of hallucinating. Document ingestion, embeddings, vector stores, and a clean query flow all come together in one walkthrough: youtu.be/EtncDnCNt9c

The workshop is tomorrow. @asm0dey.site and Anton Weiss will show how small tweaks to a Spring fat-JAR image can make scaling on K8s feel a lot more predictable. Register: bit.ly/3MkTNiS

Scaling Spring apps on K8s is harder when you rely on a basic fat JAR image. On Dec 3, @asm0dey.site and Anton Weiss from PerfectScale by DoiT will walk through building a leaner Spring image and running it more efficiently on a cluster. Save your seat: bit.ly/3MkTNiS

This Friday, Nov 21, @asm0dey.site is speaking at JUG.CY in Nicosia. If you’re around, join the meetup at Wrike Cyprus for a deep dive into building better Docker images for Spring apps: www.meetup.com/jug-cy/event...

We’re live! JRush Ep.6 is streaming now 🚀 First up: hacking Paketo Buildpacks with custom AOT caching. Then: IDE security & zero-CVE containers straight from JetBrains and BellSoft. Join us live: www.youtube.com/live/RzbPTCz...

New in #Java25: flexible constructor bodies (JEP 513)! You can now validate arguments or do setup work before an explicit constructor invocation – no more boilerplate helper methods.

JRush is tomorrow, and it’s all about #Java in containers. Buildpacks, IDE security, zero-CVE images – 3 expert talks in 100 minutes. Last chance to register: jrush.bell-sw.com/episode6

Most CVEs don’t live in your code, they live in your base image. At JRush Ep.6, @cat-edelveis.bsky.social (BellSoft) shows how hardened, zero-CVE containers change that, making #Java services secure by design. Live on Nov 18: jrush.bell-sw.com/episode6

SSE can break LLM token parcing resulting in a spaceless response. In a new video, @cat-edelveis.bsky.social shows how to fix it using NDJSON with Spring AI and WebFlux. A clean, stable way to stream tokens in real apps: youtu.be/l6c0H51fIRQ

Security starts earlier than you think. At JRush Ep.6, Grigorii Liullin (JetBrains) shows how to find and fix vulns right in your IDE with taint analysis, pattern matching & smart dependency checks. Live on Nov 18: jrush.bell-sw.com/episode6
