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 Tomas Langer (@langer_tomas) about: The first line of code was in Basic on Atari 800 XE in 1989, computer club for kids in Prague, the programming accident in Java, studying and working for 16h a day, early interests in application servers, joining BEA Systems in 2003 and starting with version 6, the weblogic.jar and the weblogic "thin client" jar, the only BEA consultant in eastern Europe, Oracle's acquisition was a big change, leaving Oracle and moving to AVG for building custom application servers, starting at HomeCredit to develop with WebLogic, service buses and Co., joining a JavaONE conference session with Josh Long about SpringBoot, what is the purpose of FatJARs, one application per server, WebLogic became bigger over time, hollow JARs are explainable, about the costs of running application servers in the cloud, the deconstruction of the application server, how clustering became obsolete, application servers and docker layers, separation of business logic and infrastructure, the superfluous deployment machinery, the idea of a single application, the complicated application server's classloading, helidon only relies on the system ClassLoader, cloud features without clouds, starting at Oracle again, Airport, Prime, J4C and Helidon, helidon was fully opensourced in February, 2019, the origin Helidon idea was to be a cloud platform, Helidon's security is similar to WebLogic 8-9 security model, helidon separates between the user and service accounts, helidon's outbound security is automated, helidon was designed with docker in mind, helidon supports hollow jars and so directly the Docker layering, FatJARs are not worth the trouble, bare metal is the killer use case for FatJARs, hardcore classloaders are problematic with GraalVM, Helidon supports MicroProfile 3.0 all parts of it, merging all infrastructural modules in a single JAR is dangerous - beans.xml and class clashes are possible, helidon comes with JWT support fo outbound communication, in helidon you can provide you own main method, helidon comes with two modes: MicroProfile and Java SE, helidon is just a set of libraries, one library happens to be the server -- but is optional, helidon started as a Java SE platform only - microprofile came later, helidon was inspired by expressjs, trying to replicate the express experience, helidon ported the Java 9 flow API to Java 8 (by renaming the package) to backport the user experience, helidon uses the event loop of netty - never block the thread, most of Jakarta EE and Java SE libraries are not reactive, Java SE and MicroProfile modes can be used at the same time, helidon Java SE application is directly compilable with GraalVM to native image, Helidon 2.0 will come with native compilation support of MicroProfile, commercial support for Helidon will be probably possible, Helidon team answers questions on slack channel, no-one is interested in providing support of outdated software, MicroProfile is volatile - backward compatibility can be a challenge, Tomas Langer on twitter: @langer_tomas and on github: https://github.com/tomas-langer

An airhacks.fm conversation with Gunnar Morling (@gunnarmorling) about: The first Debezium commit, Randal Hauch, DBs-iuim, Java Content Repository JCR / modshape, exploring the Change Data Capture (CDC), how Debezium started, the MySQL binlog, the logical decoding in Postgres, Oracle Advanced Queuing, update triggers, Java Message System (JMS), there is no read detection, switching the current user at JDBC connection for audit purposes, helping Debezium with additional metadata table, using Kafka Streams to join the metadata and the payload, installing the logical decoding plugins into PostgreSQL, logical decoding plugin exposes the data from the write ahead log, decoding into protocol buffers with decoderbufs, in cloud environments like e.g. Amazon RDS you are not allowed to install any plugins, wal2json is verbose but comes preinstalled on RDS, pgoutput is responsible for the actual decoding of the events, debezium only sees committed transactions, debezium is mainly written in Java, decoderbufs was written by community and included to debezium, Debezium communicates with Postgres via the JDBC / Postgres API, pgoutput format is converted into Kafka Connector source format, Kafka Connect is a framework for running connectors, Kafka Connect comes with sink and source connectors, Kafka Connect comes with connector specific connectors like e.g. StringConverter, Converters are not Serializers, Debezium ships as Kafka Connect plugin, Kafka Connector runs as standalone process, running Debezium in embedded mode, JPA cache invalidation with Debezium, converting Debezium events into CDI events, converting database changes to WebSockets events, database polling vs the Debezium approach, DB2 will support Debezium, Oracle support is "on the horizon", Oracle LogmMiner, Oracle XStream, Debezium supports Microsoft SQL Server (starting with Enterprise license), Apache Pulsar comes with Debezium out-of-the-box, Pulsar IO, running Debezium as standalone service with outbounds APIs, MongoDB supports the "Debezium Change Event Format", Kafka Sink connectors are easy to implement, Debezium embedded mode and offsets, embedded connector has to remember the offset, an offset API is available for embedded Debezium connectors, combining CDC with Kafka Streams, Quarkus supports Kafka Streams and Reactive Messaging, Quarkus and Kafka Streams, Quarkus supports Kafka Streams in dev mode, replacing Hibernate Envers with Debezium, Messaging vs. Streaming or JMS vs. Kafka, Kafka is a database, the possible Debezium features, Cassandra support is coming, Outbox pattern is going to be better supported, transactional event grouping, dedicated topic for transaction demarcations, commercial support for Debezium, Debezium exposes JMX metrics, Five Advantages of Log-Based Change Data Capture, Reliable Microservices Data Exchange With the Outbox Pattern, Automating Cache Invalidation With Change Data Capture Gunnar Morling on twitter: @gunnarmorling and github: https://github.com/gunnarmorling.

An airhacks.fm conversation with Ondrej Chaloupka (@_chalda) about: RPG character generators with Turbo Pascal, Delphi and Visual Basic. D&D, Pentium 100 and Atari 500 ST, the joy of programming, the object oriented paradigm with Java 1.5 at university, warehouse software with JBoss 5 and enterprise Java, the first line of Java code was "public static void main", Java is not the ideal language to start programming with, building Swing apps at the University of Brno, studying computer science was hard, computer theory at the university is actually useful, design pattern overuse is an enterprise Java disease, some best practices move to Java EE platform - there is not need to solve the already solved problems, internship in Brazil with PHP and JQuery in 2009, the main problem of early Java EE was slow deployments, starting at RedHat as quality engineer for JBoss AS 7, quality insurance is a great way of on-boarding, starting to work on transactions, most PHP applications were built with "auto commit" transactions, transactions are convenient, enhancing code coverage for the transaction manager, fixing own bugs filed as quality engineer, starting as narayana developer, narayana, arjuna and JBoss Transaction Manager are the same bits, migrating narayana to MicroProfile Long Running Action (LRA), building transactional file system JCA connectorz, the narayana bootstrap with XML (timeout, implementation, recovery, transaction log), transaction manager and transaction recovery manager are the key parts, the transaction recovery manager is needed to remember what the server did, XID vs. Global ID, transaction context is stored in a ThreadLocal, joining transactions with JPA EntityManager, UnitOfWork in EntityManager, JDBC and XA transactions, a XA JDBC driver has to be exposed to the TransactionManager, a local transaction can be directly managed by the EntityManager, the XA / 2PC (two phase commit) protocol in detail, EntityManager: transactions and flushing, XA optimizations, Quarkus and Narayana, storing transaction logs in a central database, @Stateless, @Transactional and UserTransaction, code simplification with CDI and EJB, premature transaction optimisation is the root of some evil, starting transactions at the boundary layer, slower performance without transactions, in business applications with some state you will always need something like local transaction, thinking differently with NoSQL, Dr. Martin Kleppmann (@martinkl) transactions, challenges with microservices and transactions.

An airhacks.fm conversation with Emmanuel Bernard (@emmanuelbernard) about: Amstrad PC 1512, the first PC computer ever made by Amstrad, two floppies are better than a hard drive, deleting double dots, C/PM OS, BIOS as cheating detection, creating snake game in BASIC, playing with Turbo Pascal, from GO TOs over loops to procedures, objects, aspects to functional programming, exploring Mandrake Linux, Tibco Messaging and C++, killing yourself with casting, the C discipline checker - an enforced linter, 120 errors caused by Coke break, no version control -- no time machine, starting with Java 1.2, replacing buttons with images in Swing / AWT, memory leaks in Java UI, creating ASP websites for fnac, building shopping cart with VB, going back with Visual Basic debugger, exploring Java as C# alternative, WebSphere vs. WebLogic, WebLogic was the JBoss of early 2000's, Apache Excalibur container, editing TopLink files with Eclipse IDE, replacing TopLink with early Hibernate, providing Hibernate support, the Rational Unified Process Workbench, hacking the organization is important, the gradient from hacking to politics, JOnAS was big in France, translating Hibernate documentation, patching Hibernate via CVS and email, Gavin King, Oracle and annotations as XML replacement, xdoclet was a great EJB annotation PoC, Cedric Beust created XDoclet, early Apache Geronimo participation, a French engineer will only tell you what you can do better, XML mapping with deeply nested annotations as prototype, EJB 3 specification comprised the component model and the persistence, Eclipse IDE was late with annotation support, working on EntityManager API with Bill Burke, joining forces with Java Data Objects (JDO) to participate on JPA, switching from fnac to JBoss, the first day at JBoss, Gaving King and Christian Bauer were Hibernate consultants, Steve Ebersole worked on Hibernate Core and Max Andersen on Eclipse tooling, Gavin King implemented an early bean validation prototype and Emmanuel took it over, contributing to a mature opensource project is really hard, Google App Engine wanted to use Hibernate as persistence backend, then google decided to use datanucleus.org, Book Driven Development is better than Conference Driven Development, Emmanuel started OGM - the Object Grid Mapper, in NoSQL space the model is simpler, JSON-P or JSON-B can be used as replacement for JPA entities, JDBC is hard to use what explains the success of ORM products, RedHat acquired JBoss, the switch from 200 employee company to 2000 employees company, developer is king at RedHat, RedHat acquired JBoss right after the introduction of JPA, becoming an architect, debezium was started by Randall Hauch then continued by Gunnar Morling, creating architecture slides with Google Docs, throughput driven optimizations, with containers throughput becomes less important, Java was designed for throughput and not memory efficiency and startup time, openJDK team, middleware team at Redhat had conversations about the future of Java on containers, Kubernetes is your cluster manager, WildFly is the flagship and the integration point, Sanne Grinovero was behind optimizations, Java's metaspace was too high, Java is a highly dynamic environment and therefore hard to optimize, the Excelsior JET VM, GCJ, Project Maxwell, GraalVM and the compiler is written in Java, WildFly Swarm became Thorntail and was an attempt to make the runtime smaller, Java's memory usage is the real problem, Quarkus came with the idea to make all the optimization at build time, not runtime, Emmanuel started Quarkus with Jason Greene and Bob McWhirter, the very first line of Quarkus code was written in a pub, the Quarkus project name was Shamrock what was the name of the pub, 3 months time for a PoC, hibernate, CDI, JAX-RS and JDBC drivers had to be optimized for the MVP, June 2018 was the very beginning of Quarkus, the shamrock pub is located in Australia, docker containers are immutable and the WAR deployment does not fit into this model, ThornTail's hollow JARs separate the business logic from the architecture, one of the Quarkus inspirations is the Play framework, Hibernate Panache got the idea from Play persistence, wad.sh watches changes and redeploys WARs on-the-fly, QuarkEE makes Quarkus look like a Java EE application, Quarkus on GraalVM is the perfect storm, Jakarta EE is a good way to reset Java EE expectations, the j4k conference, Emmanuel Bernard on twitter: @emmanuelbernard, Emannuel's website: https://emmanuelbernard.com

An airhacks.fm conversation with Sebastien Blanc (@sebi2706) about: Thomson MO5, every school in France needs to have a computer, printing the name with BASIC, the REM sadness, making yellow boxes, programming Logo in French, writing "root" and "house" procedures, no procedures in BASIC, the ACSLogo for Mac OS X, Berkeley Logo (UCBLogo), the Amstrad PC1512, using AMOS programming language for writing games, writing invoicing software with 14 and AMOS, Zak McKracken and the Alien Mindbenders, Siemens Nixdorf PC, QuickBasic on Siemens Nixdorf DX2-66, the Persistence of Vision Raytracer, average calculation for school notes with QuickBasic, writing ballistic games for TI BASIC (TI 99/4A), playing Nirvana on e-guitar, starting with Java in 2002, the Rational Rose Logo Edition, learning Java EE on JOnAS, Apache Tapestry, consulting with Apache Jetspeed, writing Java EE code for 7 years, hardtimes with WebSphere, Xerces and ClassLoading, refactorings to Maven, mobile web / Grails involvements, starting at RedHat's mobile team - AeroGear, Matthias Wessendorf, Matthias loves Java Server Faces (JSF), the unified push server, starting keycloak involvement, the security challenge, the keycloak religion, keycloak ships as WildFly distribution, keycloak is a WildFly subsystem, keycloak uses hibernate for persistence, keycloak manages users with credentials, keycloak ships with ready to UI to manage users, keycloak functionality is exposed as REST services, there is a Java client available - as REST wrapper, keycloak is a "remote" proxy realm, keycloak ships with adapters for major application servers out-of-the-box, keycloak comes with SSO - different application servers can share the same session, the security realm is a "territory", in keycloak a session is optional -- a microservice can use JWT token, using OIDC tokens, keycloak comes with servlet filters for servers without adapter support, the new keycloak approach is the Keycloak Gatekeeper, Keycloak Gatekeeper is a sidecar service, apache mod_auth_openidc, keycloak is oidc compliant -- any generic OIDC library should work, the JWT creation tool JWTenizr, the "Securing JAX-RS Endpoints with JWT" screencast, the oauth flows, oauth authorization flow, implicit flow and the hybrid flow, access token has to have short lifetime, using services accounts for schedulers, keycloak has a logout backchannel - available from servlet filter, pushing a timestamp also causes logout, HttpServletRequest#logout also logouts, the killer feature: keycloak stores the private keys in one place and makes public keys available via URI, Sebastien Blanc on twitter: @sebi2706

An airhacks.fm conversation with Matthias Reining (@MatthiasReining) about: Power Basic is not QBasic and was comparable with Turbo Pascal, game high score manipulation as programming motivation, C 64 was the first computer encounter, writing a "Jump and Run" game in Power Basic, Power Basic IDE as Christmas present, the menu bar fascination, using GW-Basic at high school, call by value vs. call by reference in Power Basic and Turbo Pascal, the Comal programming language, learning C, the University of Wuerzburg, learning Visual C++ and object oriented programming at university, C over C++, learning Java during internship at Nobiscum, writing a Java frontend with AWT for CVS as proof of concept, renaming com.sun.swing to javax.swing, switching to Lotus Notes as consultant, improving Lotus Notes user interface with Java, accessing Lotus Notes with JDBC, CouchDB the Lotus Notes "successor" created by Damien Katz - a former Lotus Notes developer, Lotus Notes the NoSQL database before the popularity of NoSQL, Transact-SQL, PL/SQL and back to Java, JSPs, Servlets, Tomcat and Apache Struts, from Java back to Pearl, the strategy of spending as much time as possible in a single project, writing fronted code with "this and that" or ES 5-the ancient JavaScript, the Java EE 5 fascination, xdoclet code generation for early EJB versions was slow, annotation-based programming with Java EE 5 improved the productivity, building a freelancer portal with Java EE 5 as proof of concept, a Java EE workshop in 2011, learning politics in Java insurance projects with "C-structs" as design pattern, enjoying PowerPoint time, founding a startup with Java EE 8 / Jakarta EE 8 and MicroProfile as technology choice, WildFly and Keycloak are the perfect technologies for a startup, focus on the business and not the technology, considering OpenLiberty and Quarkus as migration target caused by slow support of MicroProfile APIs by WildFly, saving memory with Quarkus, making WARs thinner by moving to MicroProfile JWT from proprietary Keycloak libraries, building the heart of an insurance company - an insurance platform, cloud-ready and private clouds are a common deployment model, migration from COBOL systems to tech11 insurance platform, team of 8 people is incredibly productive, it is hard to find good developers in Germany, hiring pragmatic developers from Afrika with the "ThinWAR" mindset, the "airhacks stack", polyglot programming is chaos, using Java EE 8 as the baseline, all other dependencies require permission, an average tech11 ThinWAR is a few hundreds kB, code snippets from 2005 gave Java EE a bad name, implement whatever you can today and care about potential problems tomorrow, the time to first commit has to be as low as possible, projects and products require different approaches, the "getting things done" developer, long-term maintenance is key to product success, every company has the right technology at certain time, Java EE is not the only "right" technology, projects are also barely dependent on Java EE, tech11 does not sell technology, tech11 sells solutions, using plain WebStandards with WebComponents, ES 6 in the frontend, Custom Elements looks like ReactJS, lit-html is one of the few dependencies in frontend, tech11 started with hyperHTML, then migrated to lit-html, open-wc comes with lots of examples with LitElement what is not necessary, using Parcel for packaging without any transpiling, rollup.js is great for packaging, Jenkins transpiles for older browsers, on developer machines not even npm is necessary, airhacks.io workshop about WebComponents: webcomponents.training, tech11 uses a BPM engine to manage processes, tarifs claims, policies are the names of microservices (ThinWARs), the episode #36 with Markus Kett mentions the JCon keynote, Matthias Reining on twitter: @MatthiasReiningand his startup: https://tech11.com

An airhacks.fm conversation with Pavel Pscheidl (@PavelPscheidl) about: Pentium 1 with 12, 75 MHz, first hello world with 17, Quake 3 friend as programming coach, starting with Java 1.6 at at the university of Hradec Kralove, second "hello world" with Operation Flashpoint, the third "hello world" was a Swing Java application as introduction to object oriented programming, introduction to enterprise Java in the 3rd year at the university, first commercial banking Java EE 6 / WebLogic project in Prague with mobile devices, working full time during the study, the first Java EE project was really successful, 2 month development time, one DTO, nor superfluous layers, using enunciate to generate the REST API, CDI and JAX-RS are a strong foundation, the first beep, fast JSF, CDI and JAX-RS deployments, the first beep, the War of Frameworks, pragmatic Java EE, "no frameworks" project at telco, reverse engineering Java EE, getting questions answered at airhacks.tv, working on PhD and statistics, starting at h2o.ai, h2o is a sillicon valley startup, h2o started as a distributed key-value store with involvement of Cliff Click, machine learning algorithms were introduced on top of distributed cache - the advent of h2o, h2o is an opensource company - see github, Driverless AI is the commercial product, Driverless AI automates cumbersome tasks, all AI heavy lifting is written in Java, h2o provides a custom java.util.Map implementation as distributed cache, random forest is great for outlier detection, the computer vision library openCV, Gradient Boosting Machine (GBM), the opensource airlines dataset, monitoring Java EE request processing queues with GBM, Generalized Linear Model (GLM), GBM vs. GLM, GBM is more explained with the decision tree as output, XGBoost, at h2o XGBoost is written in C and comes with JNI Java interface, XGBoost works well on GPUs, XGBoost is like GBM but optimized for GPUs, Word2vec, Deep Learning (Neural Networks), h2o generates a directly usable archive with the trained model -- and is directly usable in Java, K-Means, k-means will try to find the answer without a teacher, AI is just predictive statistics on steroids, Isolation Random Forest, IRF was designed for outlier detection, and K-Means was not, Naïve Bayes Classifier is rarely used in practice - it assumes no relation between the features, Stacking is the combination of algorithms to improve the results, AutoML: Automatic Machine Learning, AutomML will try to find the right combination of algorithms to match the outcome, h2o provides a set of connectors: csv, JDBC, amazon S3, Google Cloud Storage, applying AI to Java EE logs, the amount of training data depends on the amount of features, for each feature you will need approx. 30 observations, h2o world - the conference, cancer prediction with machine learning, preserving wildlife with AI, using AI for spider categorization Pavel Pscheidl on twitter: @PavelPscheidl, Pavel's blog: pavel.cool
