Ever heard of dynamic meta-compilation? Truffle uses partial evaluation to turn interpreters into optimized machine code without requiring you to write a compiler. We’ve added docs explaining how it works. Readable by humans, too: github.com/oracle/graal/blob…

GraalVM compiles applications into native executables that start instantly, scale fast, and use fewer compute resources 🚀 - oracle/graal

We used to review patch files of each other back in the day. Sent via email. Now its patch files + host snapshot with UI in a multiplayer chat interface with agents. This is just another flavour of PR. Better integrated, but not so different if you ask me.

Using @GraalVM native image to AOT compile Java base and javac is still giving another 3-4x better numbers. And this without the need for a training run. github.com/thomaswue/crema-s…

Java eats RAM? The GraalVM native image ran the same app at 40-45MB vs Rust's 20-30MB. Comparable. Full episode: youtu.be/skObnUPT1Ic #Java #GraalVM

I have to admit, I don't feel bad for Adobe. But it is probably coming for the entire industry.

AI is now being used to recreate Adobe’s software, a developer has released seven free, open-source apps as clean-room alternatives to Adobe’s main tools: - PhotoCraft → Photoshop - VectorCraft → Illustrator - FilmCraft → Premiere Pro - LightCraft → Lightroom - EffectCraft → After Effects - DesignCraft → InDesign - PrintCraft → Acrobat Pro Built in Rust with help from Claude Opus 5.5, they run on Windows, Linux, and macOS under MIT/Apache licenses without using Adobe’s source code.

It's a pity JVMCI was removed from OpenJDK now that Graal CE JIT gets faster than C2. Graal CE 25.4.4 Native Image performance improved significantly. The last missing feature is probably PGO. Shenandoah for NI is coming along nicely too #graalvm @graalvm github.com/simonis/Renaissan…

May the best abstractions win!
Matt Pocock
@mattpocockukOct 3
My hot take from chatting to @poteto is that we should use MORE abstractions in the AI age You can use them (combined with harsh lint rules) to reduce the design space available to the agent and constrain them only to good decisions. Combined with the fact that high-leverage abstractions let you do more with less code - so, more token efficient. Plus, unwinding the damage from a bad abstraction is much cheaper with agents. This runs counter to a lot of folks thinking that agents just want to read the raw code. They can, but they're not maximally efficient that way. Be braver! Design abstractions.

Besides the obvious waste of tokens, it is a complete productivity killer to look at your agents like this.
