An airhacks.fm conversation with Thomas Wuerthinger (@thomaswue) about: Working on HotSpot, Sun started collaboration with Johannes Kepler University (JKU) in Linz, Java HotSpot is written in C++, "Array Bounds Check Elimination" for Java HotSpot Compiler, increased the performance by approx. 10%, the possibly most impactful student work ever, IdealGraphVisualizer (IGV): the graphical visualisation tool for HotSpot uses NetBeans visual library, IGV is also used for GraalVM, the Maxine Research VM at Sun Microsystems, Project Maxwell was renamed to Maxine, working at Sun's Menlo Park at Maxine, the circular optimization of Java leads to higher performance, the relation between Maxine and GraalVM, replacing the Maxine Compiler with Client HotSpot Compiler "transpiled" from C++ to Java, the C1X compiler, maxine was too ambitious, GraalVM just focusses on the compiler and makes it available for HotSpot, the Java compiler (javac) is written in Java, the quality of the JIT output is the first factor for good performance, HotSpot asks JIT to optimize "hot" methods, Maxine project is stil active, JVMCI, working on crankshaft compiler at Google with a team of 8 people, using Graal as polyglot environment, converting JavaScript to GraalIR was too complex, JavaScript is dynamic and GraalIR is typed, partial evaluation was inspired by PyPy, JavaScript interpreter was written in Java and is optimized by GraalVM, the frozen interpreters, the meta-circularity comes with the native image, a small JavaScript interpreter team implements recent JavaScript features, improving serverside ReactJS rendering performance with GraalVM, R, Ruby and Python are exectly the same integrated as JavaScript, Java is going to be interpreted in the same way as well, method inlining across language boundaries, Truffle is the intepreter API and comes with language-independent tooling, GraalVM is able to output bitcode instead of native code with LLVM, native image was used to compile the Graal compiler itself, the native image contains garbage collector, native image is considered "early adopters" technology, HotSpot mode is still 20% to 50% faster, G1 is going to be available on the native image as well, in future the performance of the AOT could vary +/-10% compared to JIT, polymorphic invocations could become faster on the native image / AOT, profile guided optimizations can be performed also ahead of time, new native images could learn from the past, the stability of AOT and JIT are similar, twitter already uses AOT for years, with Java you have the choice between AOT and JIT, unikernels could be supported by GraalVM in future, the GraalVM is hiring, Thomas Wuerthinger on twitter: @thomaswue

An airhacks.fm conversation with Thomas Wuerthinger (@thomaswue) about: JavaScript on Pentium 3, snake with turbo pascal, sister as inspiration, the "view source" JavaScript approach, creating a platform "4b" site like FaceBook or studiVZ as first serious application with PHP on the backend and JavaScript on the frontend, using flat files as database, building GameScript with a subset of JavaScript to help colleagues to start programming, creating the first, interpreted, programming language, writing parsers by hand, the natural way to ASTs, creating software for smart homes, first commercial project with 16 - a visual programming language, great QT, how to skip a class, the two type of teachers, attending university classes before university, the best four Austrian programmers attending the competition are part of the GraalVM team now, the programming competition takes two days, five hours each, Pascal, Java or C were the languages of choice, mistakes cost time, programming is super fast and debugging is low, training for programming competition 2-3h a day, training with USA Computing Olympiad was almost like gaming, it's impossible to win a programming competition without training, ACM contest for students, a team of three students shares a computer, learning C with JavaScript background, difficulties with the constructor concept, the president of Austria attending the phd ceremony Thomas Wuerthinger on twitter: @thomaswue, Thomas' website.

An airhacks.fm conversation with Alex Soto (@alexsotob) about: Director of Developer Experience, Quarkus was secret at the beginning at RedHat, replacing Micronaut with Quarkus, public Quarkus release, Micronaut comes with its own API, Quarkus is more familiar for WildFly / Java EE / Jakarta EE developers, Quarkus separates the business logic from the infrastructure, Quarkus also supports FatJARs / UeberJARs but this feature is pointless for container deployments, Quarkus and FatJARs are interesting for desktop, electron-like deployments, The Quarkus Cookbook, quarkus disabling HTTP cache, kaffein cache, quarkus and batch processing -- building CLIs with quarkus, combining quarkus with picocli, quarkus integrates kafka kstreams without the necessity of including JAX-RS, airhacks.fm episode #23 with alexis about glassfish, the easy loading vs. eager loading trade off, quarkus optimizes hibernate, tree shaking of JDBC-drivers in quarkus, proactively introducing DAOs: "Generic CRUD Service aka DAO - EJB 3.1/0 Code - Only If You Really Needed" then deleting them, the quarkus developer mode mvn compile quarkus:dev, dynamically adding columns with Panache in development mode, adding extensions on-the-fly, mapping kafka streams to websockets with microprofile reactive streams, quarkus should support both: application.properties and mp-config.properties, The Quarkus cookbook is going to be published in summer 2020, writing kubernetes operators with quarkus, the quarkus vault integration, airhacks.tv quarkus / vault questions, the vault sidecar container, Alex Soto on twitter: @alexsotob

An airhacks.fm conversation with Tanja Obradovic (@TanjaEclipse) about: The amazing rainbow wires, obsessed with tetris, programming: seeing immediate results is great, basic, pascal, fortran, c, c++ and FoxPro, Smalltalk in Canada, exposed to programming, pascal did more than basic, SmallTalk is clean and logical, object oriented programming was hyped, The Object People, programming over electronics, using TopLink to access databases, messaging between object was a challenge for a C++ programmer, objects talk like people, there are no blocks in Java, meta inheritance in SmallTalk and Java, business driven decisions matter, it is easier for C and C++ programmers to learn Java, than SmallTalk, working with TopLink as consultant, the acquisition of the consulting The Object People by BEA, the TopLink product was acquired by WebGain, Oracle acquired WebGain, Oracle acquired BEA, TopLink was migrated to Java by the Object People, enjoying to work as team lead, now its time to start programming again with MicroProfile and Jakarta EE, joining Eclipse Foundation, preparing Jakarta EE for the cloud era, Jakarta EE is a huge amount of work, starting to work on Jakarta EE 9, the big bang move to jakarta.* namespace, identifying the priorities was a major challenge, addressing one problem a time with more frequent Jakarta EE releases is the preferred approach, Jakarta EE and Java EE were synonyms for complexity, the Jakarta ONE livestream, Tanja Obradovic on twitter: @TanjaEclipse, Tanja's blog: https://blogs.eclipse.org/blogs/tanja-obradovic
