#50 The Jakarta EE / MicroProfile and WebStandards Startup

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,

#49 KISS Java EE, MicroProfile, AI, (Deep) Machine Learning

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

#48 Quarkus is the Opposite of Wildfly

An airhacks.fm conversation with Dimitris Andreadis (@dandreadis) about:
Amstrad CPC 484, but Commodore had better games, learning BASIC driven by lack of games, hacking game loaders, C is the favourite language, with C you have the full control, C is concise, ISO DEE, writing ISO network layers in Ireland, writing reactive code in 1994, beautiful C code, processing bibliographic data with DSLs, maintaining passion and fun at indexdata.dk, enjoying the time at navy, clueless mainframe operators, writing programs in COBOL instead of queries, PDP 11 as simulator for naval training, writing application servers in C++ for telecom, EJB-like components in C++, Java UIs in 1998, Java should be good enough for writing service provisoning platforms, accidental discovery of Java Management Extension (JMX), first Java impression was not as good, JBoss was a heavy JMX user, JBoss was always manageable because of JMX, Rickard Öberg was a genious, dynamic kernel with dynamic extensions, Marc Fleury started JBoss, JBoss 2 was a rewrite, JBoss 2 kernel was the base for project "Junction" renamed to Action Streamer, JBoss became more interesting than the day job, core JBoss developer since 2004, CORBA / CSIv2 skills were needed for J2EE certification, transferring transactions and security context with CORBA extensions, JBoss was the first J2EE certified server, Dimitris was project lead for JBoss 4 and 5, later manager, now responsible for Thorntail, Vertx and Quarkus, in JBoss CORBA objects were dynamically generated, the paper: "The JBoss Extensible Server" from brazilian professor, Thrift, gRPC and Co. are CORBA, just reinvented, CORBA network layer is very efficient, EJBs killed CORBA, JBoss unified the web container and EJB container in a single JVM to prevent remote communication, microservices are distributed, sometimes unnecessarily, EJBs and WebContainers had to split into separate JVMs back then as well, Quarkus is the exact opposite of WildFly, Quarkus and WildFly also have different goals, the WildFly.next discussions at RedHat, Jason Greene and Bob McWhirter had WildFly discussions, Emanuel proposed a single runtime for everyone, the one base runtime for everyone prototype, SubstrateVM produced the best native code, Hibernate on Quarkus was a break-through, Quarkus is a collective, interdisciplinary effort at RedHat, Quarkus started in spring 2018, Quarkus pushes the Java EE deployment model further and the optimisations are collateral, Quarkus looks and feels like Java EE or MicroProfile, Quarkus does not require proprietary imports, Quarkus went for native optimization, and optimized HotSpot JVM as well, Quarkus build makes code less memory hungry at HotSpot, Quarkus takes have of the memory with fast startup time, Quarkus comes also with runtime improvements in HotSpot and native mode, the idea for build-time optimizations started at WildFly, with pre-computing the deployment model, Quarkus extension model allows the integration of 3rd-party code for native compilation, Quarkus development mode comes with scripting-like experience, Quarkus FatJars aren't fat, nor self-contained, Quarkus runner-jars are optimized for Docker and so clouds, Quarkus offers imerative and reactive APIs, Netty, Vert.x and Undertow are unified inside Quarkus, Panache ORM is an experiment, but could become a MicroProfile or Jakarta EE standard, working with standards is difficult, Quarkus pushes standards further, developers hack the code first, then standard comes, writing Kubernetes operators with Quarkus

#47 Jakarta EE and MicroProfile Innovation, Developer Experience and No Politics

An airhacks.fm conversation with Sebastian Daschner (@sdaschner) about:
Proposal on Jakarta EE’s innovation & relationship to MicroProfile, using MicroProfile as an incubator, JCrete is not vacations, MicroProfile is production ready, MicroProfile Metrics, MicroProfile Fault Tolerance, MicroProfile OpenApi, MicroProfile OpenTracing the incubation process for Jakarta EE, applying what made Java EE great to Jakarta EE, the difference between EE4J and the incubator proposal, the umbrella Java EE specification is lacking in Jakarta EE, predefined templates with convention over configuration and design principles, Jakarta EE and MicroProfile websites are not consistent enough, how to bring together Jakarta EE and MicroProfile, bundling Jakarta EE and MicroProfile APIs, the Jakarta EE usability project, the developer experience project, proposing a gist-like repository with common "Jakarta EE / MicroProfile look and feel" code snippets, both: MicroProfile and Jakarta EE could use the "jakarta" namespace, MicroProfile will have to refactor the packages anyway, focus on speed in developer workflow, OpenLiberty has a fast-deployment maven plugin, in "enterprise" Java there is almost no "enterprise" left, moving from Java EE to Jakarta EE will solve the marketing issue,

#46 OpenSource and Math Never Lies

An airhacks.fm conversation with Amelia Eiras-Blevins (@ameliaeiras) about:
physics and math studies, in Ecuador you have to choose your major earlier, changing from computer science to finance, without learning, everything becomes boring, the math never lies and is therefore simple, the formulas and understanding the "why", it is not about the frameworks, it is about the principles, choosing calculus for fun, the dry C and C++ without microprofile, the NAG Numerical Library for Fortran, The Gödel, Escher, Bach Book: An Eternal Golden Braid the untold secrets about David Blevins, Apache TomEE, it is not about titles, it is about responsibilities, growth can be healthy, the relation between TomEE and Tomitribe is similar to the relation of Glassfish and Payara, Tomitribe provides support for TomEE, Tomcat and ActiveMQ, Tomtribe partners with Sonatype to provide patches faster, OpenSource is not a business model, Apache Las Vegas conference happens before CodeONE, opensource projects should not just survive with the sponsor's help, TomEE comprises nine top level Apache projects, commercial support saves time and money, Sun created JCP, Sun welcomed everyone else, 410 Java Specification Requests (JSR) were submitted and about 130 rejected, 59 IP owners are asked to transfer their knowledge from JCP to Eclipse, JCP was a great success, JCP came with documentation out-of-the box, Jakarta EE Working Groups are the successor of JCP, large companies are not evil, but they are not always reasonable, MicroProfile was founded 3 years ago, JSR 382: Configuration API 1.0 was filed under the Eclipse Foundation Inc. name, MicroProfile highly welcomes contributions, if you have ideas - implement it, MicroProfile comes with flat organizational structure, it is easier to start a MicroProfile project, than an Apache project, the Tomitribe projects, the Tribestream API gateway, Tribestream was launched at CodeONE, TomEE does good and Tomitribe even better, make your first commit and you get a nice banner,

#45 Why Wizards Hate Dependency Injection with Aspects

An airhacks.fm conversation with Jarek Ratajski (@jarek000000) about:
Starting programming immediately with C 64, mysterious machines, touching the ZX spectrum once, amazing TV show about science Sonda, unofficial access to adults library, learning C64 basic with Atari ST manual, learning assembly because of: SYS 2064, GOTO and sisters, writing encryption software, writing the Snake game, writing Pong in Haskell, reinventing the C by writing assembly macros on Amiga 500, writing simulation for the stock market with Windows 95 and C, the Trumpet Winsock, first good experience with Swing programming and Forte for Java, problem with Borland C++ licenses, publishing software with Java, linux had great C-compilers but no mainstream UI libraries, "Java must go away", Java Vectors and Hashtables, writing Content Management Systems with Java, converted JavaScript developers, JSP-only projects, fear of reuse, the HashTable pattern, probably Java won't disappear, becoming Java advocate, first projects with JServ, WebSphere 1, W3C Jigsaw, Tomcat 3 was better behaving, than jserv, Caucho's Resin, migrating to EJB 3 and Java EE, writing commercial Java game with JMonkey Engine and JBoss backend, fighting with interfaces and over-engineering, the wizard look and feel, appearing in a bank as wizard, container injection is not needed, constructors are the perfect replacement for dependency injection, aspects are problematic, try and error programming leads to mess, @PostConstruct is one of the most insane constructs, writing just POJOs, Slaying Sacred Cows: Deconstructing Dependency Injection by Tomer Gabel, the real problem are aspects, CDI on Tomcat, Java's dynamic proxy, ratpack and jooq, building servers with libraries without classpath scanning, Time Injection would be useful,

#44 Plugging Things Together With Reactive Programming

An airhacks.fm conversation with Gordon Hutchison (@gordhut) about:
Playing chess with zx81, huge computer scene in Glasgow, BBC micro then saving for Acron Electron -- the cheaper BBC Micro, programming text adventure games, Forth on RML 380 Z, Sun's OpenBoot was written in Forth, Dragon 32, controlling the computer world with 13, programming colourful fractals, "do whatever you have permission to", then accessing the printer queue, transactions research and Java, IBM develops Java Transaction Service (JTS), travelling to Javasoft in Silicon Valley to transfer the JTS knowledge, moving from JTS to JVM implementation group at JDK 1.2 timeframe, having fun with IBM Java classloader, heap corruption, "lighter" experience with Eclipse RCP, Java Transaction API, Java Transaction Service and CORBA's Object Transaction Service, tranactions are a gift, just learn databases, "we don't need your transactions" in 2006, reused blog post from 15 years ago will be a big hit, IT became fashion -- everything is just reframed, implementing RAID algorithms, enjoying Java EE experience with OpenLiberty, deploying 50 times a conference session with wad.sh, having more coffee with classic WebSphere, OpenLiberty loose applications, OpenLiberty guide to loose applications, starting TX at facade level, JPA and transactions, getting two copies of the same object in the same request, every request is a transaction, loosing up the thread context, project Loom, transactions are making the developer's live simple, the pre-prepare phase, errors on CICS vs. MTS, solving the transaction diamond problem, reactive programming and backpressure, application servers and backpressure, you are not Google, reactive platform at Uber, too much sophistication, too complex to debug, and the human problem, functional reactive programming, plugging things together in reactive programming is appealing, the simple interface between publisher and subscriber, reactive programming as integration hub, learn Java streams first and reactive concepts will come easily, HTTP request / response model does not fit well with reactive programming, backpressure and kafka, Kafka's configuration, reactive streams operators as enabling layer, microprofile reactive messaging is similar to Message Driven Beans, Event Sourcing with debezium.io and Apache Kafka, event sourcing with GRPC, Apache Pulsar the "Kafka.next", SmallRye, CloudEvents and MicroProfile, SOAP envelope

#43 New and Familiar at the Same Time

An airhacks.fm conversation with John Clingan (@jclingan) about:
Using TRS 80 and owning a Commodore 64, arcade 101 at high school, computers were special at Chicago's schools, TRS 80 basic, C 64 for Christmas, typing-in applications from Commodore 64 magazine, writing self-modifying code with assembly on Commodore 64, Peeks and Pokes in BASIC and sound chip, PC at college, Cameron Purdy (#16 airhacks.fm episode) to hack 16h to complete a program, because there was no way to save it, misusing Lloyd as 60 words per minute fast Datasette, peek and pokes in a loop, immediate Unix love, PDP 11 at the computer center, writing custom forms as a student, c shell and the rouge ascii game, Minix was not free, coherent UNIX on 10 floppies, lilo, destroying the Windows MBR with dd, from C shell and Ultrix to HP UX, writing data acquisition systems at Maytag, HP 8652 Basic programs for data acquisition, sending data to UNIX system written in C, Maytag is a refrigerator company based in Iowa, writing Java at Household International, moving HP UX Unix to the desktops, running Solaris on PCs, unbelievable under construction Duke applet, starting NetObjective after playing with Java, writing Telnet in Java, the first namespace hysteria in Swing - com.sun.swing was migrated to javax.swing, selling E10Ks in 1997, Ultra Sparc, Jini and JXTA, IDE as JINI application, how memory problems made a great JINI leasing demo, picking appservers in early 2000's, autofs mount as newsreader by following the path backwards, Jiro, iPlanet in 2005, who cares about your GlassFish modularisation?, Java EE WebProfile forced the modularisaion, HK2 module system, Kohsuke Kawaguchi, Jerome Dochez, Hk2 the layer above OSGi, OSGi enterprise in GlassFish was a wasted investment, GlassFish could not find a home at Oracle, the end of commercial GlassFish, Oracle was very straight forward with their customers and top down in the company, Thorntail will move forward until the end of its lifecycle, quarkus.io is the true innovation, living in quarkus.io dev mode, quarkus is new and familiar at the same time, the first Quarkus commit was in 2018, QuarkEE as out-of-the-box experience, John isn't a QuarkEE fan, QuarkEE uses twice as much RAM, Java's RAM consumption is a problem for certain customers and Quarkus can save it, RAM is cheap but not the servers, out-of-the-box experience matters, Panache ORM - the simple ORM but could become a MicroProfile standard, it is hard to innovate without breaking changes, the day "-1" MicroProfile conference call, javax namespace issue, John is tending towards gradual transition of javax namespace, there is no backout from clean cut

#42 Payara Micro vs./or Payara Server Full

An airhacks.fm conversation with Steve Millidge (@l33tj4v4) about:
60-70% growth every year, customer base is growing quickly, 30 employees, great team with great vision, Payara is self-founded by commercial support fees, there are a lot of "traditional" applications in production, not every application needs Kubernetes, Payara clients are running their software on bare metal and on containerized platforms, it doesn't take much to support Kubernetes, Docker and Kubernetes are infrastructure and not a programming model, Java EE programming model is productive and can be taken to Docker and Kubernetes infrastructure, config externalization is the major task for Kubernetes support, Payara clustering discovery service uses Kubernetes for lookup, Payara Admin server is able to manage Payara Docker nodes, Payara Admin could replace the Kubernetes scheduler, scalability based on business metrics, the JavaONE GlassFish 3 cloud demo, aggregating metrics in a cluster, Payara Clustering brings data closer to processing, Payara Cluster is a distributed cache aka data grid, smart proxies with JAX-RS, CORBA was replaced by JAX-RS, load balancing with JAX-RS, in Payara 5 deployment groups and data grid comprise a cluster, Payara Server and Payara Micro support both MicroProfile and Java EE 8, application server as managed runtime, Payara comes with request tracing, database monitoring, upcoming releases will expose more metrics. you should not need an APM tool to monitor an application server, Canadian government contributes to LightFish, guidance for Maven bloat prevention, Payara Source To Image (S2I) https://github.com/AdamBien/s2i-payara and Payara Micro Source To Image (S2I) https://github.com/AdamBien/s2i-payara-micro, Payara Server supports more APIs than Payara Micro, Payara Server is capable to manage multiple instances and comes with admin console, Payara Micro runs on its own and is designed to run within docker containers, clouds and kubernetes, you could start with Payara Server and migrate to Payara Micro later, Payara Server and Payara Micro runtimes are similar, Payara Micro does not support OSGi - what is a feature, the only runtime difference between Payara Full and Micro is OSGi, Payara Micro doesn't have to be installed, the core development happens on Payara Server, Payara Micro is just repackaging of Payara Server, Payara Micro uses hardcoded classpath, the javax Jakarta EE namespace issue, Java EE backward compatibility is great feature and also a weakness, Jakarta EE is boring, MicroProfile iterates more quickly, Jakarta EE release cadence could be once every 2 year, MicroProfile releases 4 times a year, Jakarta EE and MicroProfile are popular in Europe, managing satellites with GlassFish, kubernetes anti-pattern, running OpenShfit cluster organization-wide

#41 Web Applications Without Frameworks

An airhacks.fm conversation with Ben Farell (@bfarrellforever) about:
copying and pasting game programming logic from magazines into a TI 994a, the ugly purple people picker, accidentally buying Java books, boring C++ without visual elements, dangerous assembly classes, Macromedia Director in 1996, developing with Flash, suddenly in 2010 Flash lost its popularity, writing casual games for kids, a thick book about LiveScript, JavaScript is just Java with a bit script, Java was great and the visual stuff was boring, writing code in key frames, Adobe Flex, Adobe Flex Builder, typesafe ActionScript, GreenSock, GreenSock started with Flash, the book about WebComponents, plain vanilla, no thrills, JavaScript, developing applications without a framework, potential migrations, stable React, JavaScript becomes more and more similar to Java, CSS 3 without less or Sass, plain lit-html and hyperhtml as fallback, template literals vs. lit-html, partial rendering with lit-html, no virtual DOM, possible security issues with plain template literals, lit-html and event binding, lit-html vs. custom attributes for wiring, separating templates and business logic with modules, bad experiences as Java developer with maintaining multiple files, CSS extensions with houdini, a standard for hooking into browser's CSS processing, is there no more need for frameworks?, frameworks as hindrance, the Vaadin Router webcomponent, building a navigation component, the magic under the hoot comes with good intentions, building fusion reactors for CRUD, using custom elements for application structuring, the reflection best practice, shadow DOM is supported on all browsers, shadow DOM is problematic with CSS design systems, Constructible Style Sheets to the rescue, start without Shadow DOM, then introduce it on demand, customizing styles with CSS properties, using IDs without Shadow DOM is hard, ShadowDOM with querySelector, Adobe Project Aero, browsersync in development mode, obsolete build systems, bunding with rollupjs and babel plugin for legacy browser support, pikapkg - the anti-bundler, 2005 EMMY for Sesame Street Games Channel, cheating with annoying Elmo, WebComponents in Action (discount code: podairhacks19): a book about making WebComponents without a framework, outdated Polymer, VR and AR with WebComponents, a-frame, Occulus Quest and Tiltbrush,

#40 Transactions, J2EE, Java EE, Jakarta EE, MicroProfile and Quarkus

An airhacks.fm conversation with Mark Little (@nmcl) about:
the 250 miles terminal connection, Commodore PET, battle ships on paper tapes, mocking the login screen on Commodore, reverse engineering Space Invaders, the lack of games in UK was a motivation for writing games, learning peek and pokes, Commodore engineering team wrote a book about machine code, Basic on BBC model B, Pascal and C on EPROMs, building a hotel booking system on Pascal, building a pseudo operating system with C, Concurrent Pascal, Cfront - the early version of C++, Atari ST came with C support, C++ over Concurrent Euclid, working with Andy Tannenbaum and Bjorne Stroustroup on Minix, porting Minix to Atari ST, Arjuna the Indian god, Indian Gods over Celtics, Arjuna -- the object oriented transaction system, started in 1985, inheriting transactions, transactions are not about HA, transactions are about recoverability, starting Java as Oak, the shiny object syndrome and transition to Java, writing web browsers in Java, porting Arjuna to Java with Blackdown Java, Jim Waldo and Note on Distributed Computing, opaque over transparent, Johan Vos was a member of the Blackdown team, RPC with C++ and Arjuna, almost serverless, packing and unpacking instances and the Lock Manager, 2PC was the default, without X/Open XA heuristics the system would block forever, XA heuristics were introduced to make independent decisions, enforcing consistency in microservices with 2PC/XA is hard, SOA and microservices come with similar challenges, there is no a single transaction model applicable for every single use case, XA/2PC is lesser suited for long running actions, transactions were out-of-fashion - now they are back, Google Spanner is transactional, Arjuna was acquired by Bluestone, Arjuna Technologies was acquired by HP, JBoss did a partial acquisition of Arjuna, before the Arjuna acquisition, JBoss couldn't handle 2PC properly, Bluestone became the HP application server, JBoss was always opensource and good quality code, J2EE came before annotations - metadata was attached with partially redundant XML, Mark became RedHat CTO in 2009, MicroProfile is great and there is a lot of interests in evolving Java into clouds by the community, Jakarta EE was a great move by Oracle in 2017, Jakarta EE has to move faster, Jakarta EE is more like the stable OS, MicroProfile is where the innovation happens, there are no more monolithic application server, what does "enterprise" mean?, QuarkEE is opinionated Quarkus,

#39 Use the Most Productive Stack You Can Get

An airhacks.fm conversation with Gunnar Morling (@gunnarmorling) about:
Eastern computers and Robotron KC 85, CPU slicing, screensaver as source code, Hello World in Pascal with 14, University in Dresden, AMD and Java 1.2 with Forte for Java, starting at Saxonia Systems as consultant, having fun in a Java EE 5 course, the EJB 3 and Guice blog post, the effect of a link, Java EE 5, the "dinsoaur version" was productive although you had to write interfaces, early EJB and J2EE were bloated, but it was 15 years ago, working at Otto the German "amazon" and Kuehne and Nagel, just use the most productive stack you can get, what does "modern" actually mean?, applying quantum computing to CRUD, it was hard to find a killer use case for WildFly Swarm, quarkus is a Java EE + MicroProfile subset with useful features, FatJars do not make any sense in a layered file system, bare metal infrastructure is the killer feature of UberJars and FatJARs, Heavyweight vs. Lightweight JavaONE session, quarkus native image is a fraction of JVM size, the "compile time boot", performing optimizations at build and not at boot time, with quarkus CDI performance might be as good as EJBs, deployment descriptors are only needed at build time, boring programming model with optimizations under the hood is true innovation, MicroProfile FaultTolerance combines easy programming model with Hystrix's capabilities, don't re-invent the wheel, BeanValidation's in XML-configuration is not supported in quarkus native mode, QuarkEE release, using quarkus for web development, validating design and architecture with deptective, deptective enforces the rules at compile time, deptective is a plugin of javac compiler, javadoc may cause package cycles, measuring packge coupling and cohesion, jacoco as code coverage plugin for quarkus, debezium detects changes and passes the events to Apache Kafka, debezium uses DB APIs, logical decoding in PostgreSQL, debezium receives updates even it the application is not running, listening on the transactional log of the database.

#38 Apache Firefighter

An airhacks.fm conversation with Mark Struberg (@struberg) about:
rubber-keyed ZX81, C64, Basic, tons of incorrect rows of hexcode, transitioning from Basic to assembly, games were an inspiration, 40mins to load the game, Turbo Copy for software refreshment, transitioning from software to solding transistors, flip-flops with 10 years, programming Logo with Atari ST, HTL in Austria, Pascal on 286 Commodore PC 20 with monochrome computer, host programming on Digital Equipment PDP 8e, Sun's pizza boxes, drinkomat the drink (also vodka) portioning machine, replacing 2 PCs with one microcontroller, the first 3D printer, testing insulin pumps, learning C++ with Glockenspiel C++ compiler, starting with Java 1.0.2, building stock exchange software with Java, brilliant Martin Poeschl, Maven 1 and Cocoon, JRun was servlet-like engine, Borland JBuilder, building platforms for Austrian insurance market platform in 1999, Lutris Enhydra application server, Tomcat was donated by Sun to Apache, never control program flow with exceptions, Jigsaw - Apache servlet engine, XMLc was a built-step in Ant, DOM manipulation in Java on the server, defining data structure in XML and generating the DAOs, enhydra was Canadian then donated to ow2, Windows and OS2 programming, C# came 2002, first EJB-drafts were nightmare, EJB could be implemented better with Objective-C Portable Distributed Objects from NeXT, EJB was a huge buzz topic pushed by Microsoft's DCOM, MTS was almost like EJB, DCOM came before EJB, MTS came after EJB, "remote first" was wrong, macroservices are more appealing for enterprise, delivering in 2004 25 TB of music (and Jamba ringtones) to 16 million customers and with Servlets and Resin from Caucho, hardcore threads were native, Mark worked as freelancer, a few big Sun Enterprise 400 with MySQL without transactions, optimizing for read only, projects under fire, the challenging part in the backend were contracts and payment, switching logic with re-deployment with Groovy, switching from Spring to CDI, refactoring PHP to Java in 5 years, Seam 2 didn't had the future, serving 5 millions impressions / 12k requests per minute in the first day with 1-month old Java EE 6, Glassfish is rubbish, Payara is great, Payara delivers patches incredibly fast, Java EE community is really nice, the real benefit of opensource is sharing costs, experience, maintenance, testing costs and fork prevention, JPA is too much magic but you get tons of answers for free, three category of projects: perfect, problematic and completely broken, the javax namespace issue, javax became immutable, Geronimo app server is dead, the Geronimo contains Java EE API specs, one-shot migration to jakarta namespace is not that hard, migrate once, but do it right, javax migration is a lorge task for vendors but a small issue for business, developers are still thinking is "J2EE", Eclipse is too protective and should open to other foundations and communities

the Java EE Testing survey and possible room for improvements, testing is too hard with severe consequences, reasonable projects are interested in delivering good software, large enterprises are more interested in statistics, testing is about increasing developer's confidence, confidence decreases with the length of time spent outside the project, in 1996 you would test with a bunch of main methods, most projects are ignoring System Tests because the statistics are not gathered, "test first" or last does not matter, you only have to deliver the tests with working software at the same time, running System Tests with code coverage, fast and long running modes, Unit-, Integration-, and System Tests are naturally ordered by their execution time, in business projects unit test coverage can be fairly low, in business projects arquillian comes with a little added value, in Integration Tests it is crucial to use the same version of libraries, tests do not accurately represent the production environment, System Tests are reused as Stress Tests, JMH is a great library for stress tests, at IBM there is a dedicated performance team, in projects torture tests are a good start, toxiproxy by shopify, management driven code metrics is a failure of management, unit tests should be about verifying the behaviour not the implementation details, too many unit tests increase the costs of refactoring, unit tests are running in seconds, integration tests in a few minutes, the performance of system tests really depends on the system, integration tests give more confidence, than unit tests, unit tests are great for productivity, running servers in code coverage modes would be useful, jacoco code coverage metrics could be exposed via JSON,

#36 Java Native Database

An airhacks.fm conversation with Markus Kett (@MarkusKett) about:
C64 and sports games, Weiden is not in Bavarian Forest, soccer as motivation for programming, writing first programs in basic with 17, writing contacts management, PCs are boring machines, but good for business, Java is the best programming language, Pentium 1 was introduced at CEBIT in 1993, the dream about an own booth at CEBIT came true, webdesign software based on applets (XPage) was very successful at SYSTEMS in Munich, Markus was the business man and had no time for programming - like Steve Jobs, self-financing with selling products, competing with Microsoft and Adobe, writing a 4GL Java-based development environment like Visual Basic called XDev, Java Developers don't like the Drag and Drop programming experience, building an IDE from scratch, discussions with Sun Microsystems about StarOffice integration, migrating from Swing to SWT and Eclipse, using Vaadin as UI technology, connecting beautiful UI to DB was too hard, databases have more types than Java what makes code generation hard, in 4GL the database comes first, RapidEclipse is free but commercial support is available, XDev provides tool and project support, RapidClipse understands rich database types and generates JPA POJOs, Hibernate importer, how to write queries in Java, implementing JPA-SQL is based on xtext by itemis and generates JPA-QL from SQL, storing data is still too complicated, serialization looked promising but was too unsecure and only entire objects can be serialized, Kryo, Fast Serializer, JetStream (renamed to Microstream) serializer, the database engine stores objects in any file storage, there is no impedance mismatch, the native Java storage engine, queries are performed with Java 8+ streams, JCA connector passes transactions and security context to the application server, JCA prototypical implementation, kubernetes persistent volumes, Bavarian Forrest is like Canada, the largest walking robot, Roding race car, being a TV host on Giga, constant 30k downloads and the XDev TV, DVDs were more successful than TV, JCon and the coding keynote, Java EE as secret weapon at JCon, stealing (adapting) the "no slides" ideas, the world first free, physical, Java magazine JAVAPRO with 8500 readers, community prefers Java-only conference,

#35 80% Code Coverage is Not Enough

An airhacks.fm conversation with James Wilson (@jgwilson42) about:
the result of pressing the break button on a BBC computer, and ZX Spectrum, Space Invaders with Basic, extending minecraft with Java, accidental tester career, best interviewees got programmer jobs, hackers and testers, developers like the happy path, unit test coverage is useless without good asserts, is 80% code coverage a valuable target?, code coverage was used as a motivation for writing tests, reflection utilities to increase code coverage, getters / setters never brake, Code as a Crime Scene book, methods longer than a screen are problematic, the ratio between trivial and good asserts, a good javadoc and unit tests follow similar principles, system tests are the most important one, unit testing is good for checking error scenarios, the more tests you have, the easier it is to locate errors, the Law of Triviality requires standard names for test categories, integration testing and system testing, reusing system tests as clients and stress tests, UK retailer goes down, take the max load and double it, jbmc is bytecode verification tool, diffblue cover generates unit tests, generating unit tests quickly for legacy backends, playground, What is the AI in “AI for Code”? blogpost, diffblue blog, @diffbluehq

#34 Kafka vs. JMS/MQ

An airhacks.fm conversation with Andrew Schofield, Chief Architect, Event Streams at IBM about:
1982, Dragon 32 and Basic Programming with 12, starting with JDK 1.0, writing a JMS provider for WebSphere v6, no ceremony JMS, Apache Kafka considered simple, why writing a Kafka application is harder than a JMS application, there is a big architectural difference between Kafka and JMS, or message queuing and event stores, Kafka remembers historical data, JMS is about fowarding messages, with Kafka it is harder to write conversational systems, clustering singletons is hard, running Kafka on a single node is easy, "deliver once and only once" is the killer feature of persistent JMS queues, JMS topics are nicer - you can send messages to unknown receivers, the killer use cases for JMS and Kafka, JMS is good for system coordination and transaction integrity, Kafka is well suited for (IoT) event buffering and re-processability, 2PC, XA and the advantages of middleware, in distributed transactions everyone has to remember everything, we only need distributed and rock-solid persistence, kubernetes pods are stateless, challenges of using Kafka, setting up for production can take months for an average Java programmer with JMS background, restarting Kafka brokers can be challenging, in Kafka you are communicating with the cluster, MQ is a collection of individual queue managers, in MQ there is a directory of resources which knows where the queues are hosted.

#33 Quarkus and ThinJARs

An airhacks.fm conversation with Stuart Douglas (@stuartwdouglas) about:
starting with Visual Basic in high school, with the goal to build games, then quick transition to C++, creating Tetris from scratch in weeks in C++, building first commercial financial planning application with PHP, starting with Java 1.5 and annotations in 2007, Java is popular in Australia, building Seam applications with JBoss 4, contributing to Weld in spare time, improving the performance and startup performance of Weld, working for RedHat as JBoss AS 7 developer, JBoss is more than the application server and the advent of Wildfly, the braning clean up, creating Undertow, WildFly was shipped with deactivated EJB pooling, too small EJB pools can cause performance issues, how to kill EJBs with CDI, EJB vs. CDI, interview with Pavel Samolysov and EJB vs. CDI performance comparison, quarkus is not using reflection for injection, a small team (8 people) started quarkus to leverage GraalVM, the goal of quarkus is to make a subset of Java EE natively compilable to an "unikernel", updating the cloud platform without recompiling the app, serverless with quarkus, serverless without the function disadvantage, 20MB self contained, native images, building Java EE / Jakarta EE unikernels, extremely fast start times for Java EE applications, native images are running with a fraction of RAM, at one point in time, quarkus might be commercially supported by RedHat, CDI portable extensions are not supported now, quarkus wizard is not based on Maven archetype - what is a great idea, Maven is only one of many possible entry points to quarkus, a really good developer experience was always the main goal, hot reload is a must, currently the classloader with the "business" part is just dropped and the app is reloaded, adding dependencies via CLI or pom.xml, quarkus ThinJARs are compatible with the ThinWAR idea, FatJAR's builds have to be slower, packaging all dependencies into a single JAR, using Chrome Dev Tools Protocols for hot reloading the browser, misusing quarkus for building command line tools, community extensions are on the roadmap, quarkus is going to be well integrated with OpenShift, quarkus forum.

#32 Jakarta EE, MicroProfile, OpenLiberty: Better Than Ice Hockey

An airhacks.fm conversation with Andrew Guibert (@andrew_guibert) about:
old IBM PCs and old school Legos, starting programming in elementary school to write video games, the market for enterprise software is better, than the market for video games, World of Warcraft is good for practicing team work, ice hockey, snowboarding and baseball, getting job at IBM by pitching Nintendo WII hacking, why Java EE is exciting for young developers, OpenLiberty is a dream team at IBM, providing Java EE support for WebSphere Liberty and WebSphere "traditional" customers, Java EE 8 was good, and MicroProfile is a good platform for innovation, quick MicroProfile iterations, sprinkling MicroProfile goodness into existing applications, MicroProfile helps glue things together, OpenLiberty strictly follows the Java EE standards, how OpenLiberty knows what Java EE 8 is, OpenLiberty is built on an OSGi runtime, features are modules with dependencies, OpenLiberty comprises public and internal features, Java EE 8 is a convenience feature which pulls in other modules / features, OpenLIberty also supports users features, OpenLiberty works with EclipseLink, as well as, Hibernate, OpenLiberty comes with generic JPA support with transaction integration, Erin Schnabel fixes OpenLiberty configuration at JavaONE, IBM booth with vi in a few seconds, Erin Schnabel is a 10x-er, IBM MQ / MQS could be the best possible developer experience as JMS provider, Liberty Bikes - a Java EE 8 / MicroProfile Tron-like game, scaling websockets with session affinity, tiny ThinWARs, there is MicroProfile discussion for JWT token production, controlling OpenLiberty from MineCraft, testing JDBC connections, BulkHeads with porcupine, all concurrency in OpenLiberty runs on single, self-tuning ThreadPool

#31 Serverless without Functions, OpenShift with a bit Istio

An airhacks.fm conversation with Sebastian Daschner (@DaschnerS) about:
being chief Enterprise Service Bus Officer at IBM (not true), Lead Java Advocate for Java at IBM (now true), Sebastian still likes Java EE, the definition of Serverless, there is no need for functions in serverless computing, a reference to episode with Bruno Borges "Jakarta EE / MicroProfile in the Clouds: Runtimes not Servers", the difference between servers and runtimes, focussing on ThinwWARs is serverless, immutable infrastructures with immutable layers, pushing 50 times a day a ThinWAR to the cloud, Payara Configured as example for intermediary layers, Payara s2i, misusing Docker Registry as "FTP", ThinWAR upload triggers a hook and rebuilds a server, ultra productive Java EE, servers do not matter, using FaaS to trigger server re-configuration, functions are too fine grained for the implementation of stock applications, implement the added value of clouds by injecting cloud services, cloud bootstrap / initialization code looks like from 1945, externalizing cloud libraries to immutable images, added value of istio at openshift, cross cutting concerns with Istio, canary releases, routes and observability, istio adds additional configuration overhead, istio adds technical features on top of openshift, a possible killer features of istio, monitoring database traffic with istio, Istio as "feel good factor", some technical dashboards are as usable as lava lamps, monitoring external services, artificially slowing down connections in tests, MQS, hello worlds with Kafka are great, two lines to send a JMS events and one annotation to receive a message, Kafka is great as managed service, the next killer feature of MQS, killer runtimes with microprofile and Java EE, you can find us at jakartaee.blog, my blog is not usable as source for articles,

#30 Optimizing For Humans

An airhacks.fm conversation with Simon Harrer (@simonharrer) about: Amstrad Laptop, first line of VB code was a commercial one, customers two desks away, Scheme is an excellent language to learn programming, Java is great - mainly because of the tool support, Eclipse was the first opensource IDE with decent refactoring support, Bamberg is the home of Schlenkerla, teaching is the best way to learn, therefore teaching is selfish, building portals for students with PHP and Joomla, building e-commerce shops for students with Ruby on Rails, 2006 everything had to be Rails, PhD about choreography and distributed transactions, too high expectations on workflow and rule engines, workflow engines are for developers and not for business people, central process view is still desirable, startups with Bosch, in Germany it is hard to find developers who are willing to join startups, Simon works for InnoQ and Stefan Tilkov, Computer Science University of Bamberg, the pragmatic book: Java by Comparison by The Pragmatic Bookshelf, in streams there are no exceptions, over-abstractions cause trouble, reviewing the code of thousands of students for six years, it is unusual for universities to promote pragmatic code, be strict about adding external libraries, clear separation between infrastructure and business logic helps with clean code, moving domain specific libraries into the infrastructure, human centered code, optimizing for machines, not for humans is problematic, writing bad code is often not intentional, "Abstract, If, Impl, Default, Bean Conventions - Just For Lazy Developers", don't write for reuse, reuse rarely happens, reuse as motivator for bad abstractions, do repeat yourself, than refactor, "How To Comment With JavaDoc", Book: Java by Comparison, Become a Java Craftsman in 70 Examples, Simon Harrer on twitter: (@simonharrer).

#29 Jakarta EE / MicroProfile in the Clouds: Runtimes not Servers

An airhacks.fm conversation with Bruno Borges about: sudden death of remote EJBs caused by Java EE 5 and Web, servers as cloud, shared deployments in E10k , separation between infrastructure and business is boring, no rocket science, application servers and immutable infrastructure, frozen application servers in Docker layers, Docker modernized deployment model without modernizing Java EE, FatJar and UeberJars are useful outside containers, Azure AppService, the actual idea of application servers is pointless, cloud hooks for building ThinWARs, extending application servers with cloud-specific features, what is actually the definition of serverless?, serverless Java EE and the events are missing, JAX-RS endpoints as event listeners, servlerless platforms and lock-in to serverless environment, shipping functions as Docker images, openfaas, killer use cases for serverless functions, the legacy perception of Java EE, MicroProfile solves the marketing problem, cloud native deployments with MicroProfile, what is the difference between servers and runtimes, lets talk about runtimes, not servers, moving away from servers to runtimes, opinionated runtimes for developer experience, Convention over Configuration was borrowed from Ruby on Rails, Don't Make Me Think, Java EE / microprofile is an interesting programming model for the cloud, there is no such a thing as standards, everything should be an event, CloudEvents is an interesting standard, MicroProfile could implement binding for CloudEvents, wrapping proprietary cloud bootstraping logic with CDI, improving developer's experience by injection proprietary cloud services, MicroProfile Azure Key Vault, Bruno can be contacted via: bruno.borges@microsoft.com (please no spam), Bruno at LinkedIn and twitter: @brunoborges
