OpenJDK: Panama

6 hours ago (openjdk.org)

Paet of Panama is the Vector API, currently in "incubation". Kotlin Notebooks are a great dataframe alternative to pandas or polars in Python (and dplyr in R), and work fine for relatively small data sets, but are indeed slower when dealing with calculations on large data. Vectors should reduce that gap significantly.

I love it how Java is "innovating" by catching up to things that other programming languages have had for three decades.

  • Well, yeah. It's the explicit design philosphy of the language to wait and see what works as other languages do the experimenting.

  • "We are improving and enriching the connections between the Java virtual machine and well-defined but “foreign” (non-Java) APIs, including many interfaces commonly used by C programmers."

    Where does it say "innovating"?

    • They are doing something new in the language -> innovating.

      JNI was always the wrong way to do FFI. FFI should require no changes or wrappers in the native code; anything short of that is unnecessary and inefficient. Yet, somehow, in Java land, this is still the norm in 2026?

      I'd really want to love Java, but man, it has a long laundry list of warts and a near-zero pace of innovation.
