No, I don’t think I will #scammers

ICYM: Java is becoming a better scripting language without turning into a toy scripting language. JBang and modern Java make automation feel a lot less disposable. www.the-main-thread.com/p/java-is-th...

Jenesis now offers all features build tools out there offer through configuration, but by detecting configuration files in the main folder. I would expect that most developers will meet a feature complete tool. Try it out: github.com/raphw/jenesi...

AI corrupts engineers and management. A topic near and dear to my heart: dierk.github.io/Home/AiCorru...

Good news! I have been added to the RubyConf 2026 schedule to present JRuby and all the ways it lets you use Ruby when CRuby doesn't fit! I'm glad that the new @rubycentral.org values community and understands the importance of JRuby. Twenty years of JRuby...don't miss this talk!

I added support for most JVM languages to Jenesis and polished the framework altogether. I also added a range of demos: github.com/raphw/jenesi... If you are interested in build tools and always thought that building on the JVM should be easier, maybe this approach is for you. Let me know!

Ran the Oesch Lauf 2026 (10k) in 00:57:43,7 The ☀️ was a 🏖️ Too hot for a race but managed to finish under an hour 🥵 feditrack.javahippie.net/activities/b...

I think I came up with a reasonable alternative for a build tool for the JVM. To give you a teaser, I want to get rid of the POM, but offer compatibility to it, given they are anywhere, but want to embrace Java Modules which work really well for this. State of modules: github.com/raphw/jenesi...
