The bug is in the compiler!
Jensen made the rounds recently, saying that people shouldn't need to learn how to code to program in the future. I agree: Coding is incidental to programming, which is the act of solving problems. Programmers will instead be orchestrating AIs. An excerpt from my TED AI talk.
The first #GraalVM native image entry made it to the #1BRC leaderboard! @thomaswue currently on #2 with that with 9.625s on the eval instance, behind @royvanrijn. Curious how much of a difference PGO would be able to make 🤓. 1⃣🐝🏎️ github.com/gunnarmorling/…
To create Gemini Ultra, @JeffDean just wrote down an integer and used it as a seed for a PRNG to generate all the weights.

TornadoVM 1.0 is out! Off-heap memory allocation is now supported via the integration with the Panama MemorySegment API, and much more! Changelog: github.com/beehive-lab/To… Guideline for migration to off-heap types: tornadovm.readthedocs.io/en/latest/offh… #opensource #Java #GPU #acceleration #AI
I ported @karpathy's llama2.c to Java: github.com/mukel/llama2.j… For large models, the JVM performs very close to the C implementation. It can even run Llama 2 7B at a whooping 1.5 tokens/s.
We just released an upgrade to WebVM. Our #WebAssembly based x86 virtual machine running completely in the browser. You can now customize the system and deploy your own version on GitHub pages with just a few clicks. Check it out! leaningtech.com/mini-webvm-you…
A JVM in the browser 🤯 a refinement of the original approach e.g. compiling Java bytecodes to JS and native dependencies to WebAssembly.

"Those who machine-learn from history are doomed to repeat it"
Web browsers are not operating systems or application development environments. They’re document viewers. The effort to make them into something more than that has been one of the biggest wrong turns in the history of computing.
Are you curious about yesterday's Java on Truffle release? Give it a try with this demo: github.com/graalvm/graalv…

And in the Runtime category, it's Graal JIT vs. Helpful NullPointerException.
TruffleRuby is now the first implementation besides CRuby to pass all of the 2180 #RubyGems' tests, no exclusions! github.com/rubygems/rubyg…
Love it! Performance home run for @TruffleRuby.

I'm happy to have helped to make the Google #Java Code Formatter available not only as JAR anymore, but now (new) as very fast platform specific native binary executables (built with #GraalVM), see github.com/google/google-…!
Google's Code Formatter for Java is now 10x faster thanks to @graalvm Native Image! 🥳
And it's already directly usable in #vscode #code @code thanks to github.com/JoseVSeb/googl…! "Formatting completed in 45ms." instead of 473ms! That x10 is actually noticeable on Ctrl-S Save a *.java, even on a fast computer - cool!
TruffleRuby is now using Prism as its Ruby parser! 🚀 This means *all* the Ruby 3.3 syntax is supported, no exception! It is also twice as fast as the previous parser written in Java! And future Ruby syntax will be available very quickly in TruffleRuby. github.com/oracle/truffle…
