This document summarizes a presentation about Oracle's GraalVM and how it can be used to run PHP code. It discusses GraalVM's just-in-time compilation capabilities and how Truffle allows PHP to run on GraalVM. Benchmark results show that a Truffle-based PHP on GraalVM has significantly faster performance than PHP's default interpreter or just-in-time compiler.

Moore's law describes the long-term trend that the number of transistors on integrated circuits doubles approximately every two years. This trend has continued for more than half a century and is a consequence of technological improvements that shrink the scale of components and allow for greater integration of more transistors on a single microchip over time. However, continued progress is not guaranteed and physical and technical limits may cause this trend to end.

JDK 10 will be released on March 20, 2018 with 12 new features. Key changes include a new 6-month release cycle, modularization of the garbage collector, experimental Java-based JIT compiler, local variable type inference, parallel full GC for G1, application class-data sharing between JVMs, ability to stop individual threads, and support for alternative memory devices like non-volatile RAM. JDK 10 also enhances support for Docker and Unicode extensions.
- Oracle announced in 2017 that Java would be released every 6 months, with feature releases in March and September and maintenance releases every 3 months in between.
- Support is provided until the next feature release, with Long Term Support provided every 3 years for the Oracle JDK.
- The new release cycle was criticized for being too short, as tools and testing need more than 6 months.
- The version numbering was changed, with JDK 10 being the next feature release in 2018.
