Dynamically generated code (with dumped classes) is now treated as a first class citizen in JITWatch, the Just In Time compilation inspector that can help you understand the optimisations made by the JVM at runtime.

This feature was contributed by JITWatch community member Andrew Oswald and has been incorporated into the 1.7.0 release.

Java 27 released

Speaking of unsexy programming, we've got a new Java release.

Featuring thousands of performance, stability, security, and productivity improvements, Java 27 (Oracle JDK 27) provides a strong foundation for continued Java innovation. To help organizations prepare for more secure communications in a post-quantum world, Java 27 advances its post-quantum cryptography (PQC) capabilities with hybrid key ex

Zwischen primitiven Typen und Klassen klafft in Java seit Jahrzehnten eine Lücke.

Auf der #BaselOne26 zeigt @sippsack, wie Project Valhalla mit Value Classes ansetzt: kompaktere Datenstrukturen, weniger Object Overhead und bessere Datenlokalität – spannend für Embeddings, Vektoren & Co.

Programm u.a. mit @gazebo_c, @martinfrancois & Bertrand Delacrétaz: https://baselone.org/#programm

This suprises me a lot. Oracle isn't a group I tend to think of as doing the right thing often, but check out the "OpenJDK Interim Policy on Generative AI".

The final policy remains to be seen, but what's up now is remarkably sensible.

Operaton users: in 2027 I'll be back at conferences and user groups to talk about the project — and for user groups I'd love to share the stage with you.

I'll cover governance, internals, what a process engine is even for. You have the interesting part: migrations, the processes you actually run on it.

No polished talk needed, 15 minutes is plenty, and we can keep the client anonymous. If there's a Java user group near you, I'll approach them together with you.

Reply or DM.

I like trying different programming languages. For fun, I benchmarked some of them (#commonlisp, #java, #lua, #picolisp) on a simple n-queen task.

This is the [repo](https://tangled.org/argo-net.bsky.social/some-pl-benchmarks-1) and this is the [analysis of results](https://argo-net.tngl.io/some-pl-benchmarks-1/).

C is the fastest; SBCL is rock solid at 2X C speed; Java starts slow but it reaches C when the problem size increase.

AI-native Tiny Teams — правильный вектор или хайп 2026 года?

В 2026 году из каждого утюга звучит тезис: несколько сильных инженеров с агентами теперь способны делать работу, для которой раньше требовалась полноценная продуктовая команда. Его подогревают прогнозы Сэма Альтмана о «единороге из одного человека» , заголовки о tiny-team moment Кремниевой долины и истории вроде Lovable: $100 млн ARR за восемь месяцев при 45 сотрудниках . В такой подаче tiny team выглядит чуть ли не как будущее разработки и почти панацея. В этом есть частичка правды. AI ускоряет исследование, прототипирование, написание кода, тестов и документации. Полевые исследования фиксируют рост производительности разработчиков , а CircleCI в State of Software Delivery 2026 показывает существенный рост throughput у наиболее эффективных команд.
