MySQL Group Replication - Ready For Production? (2018-04)Kenny Gryp
At the end of 2016, Oracle released a new Plugin called MySQL Group Replication, which is a new MySQL replication method that aims to provide better High Availability, and built-in failover with consistency guarantees.
I evaluated the initial GA versions back in early 2017. I presented my initial findings with several best practices and concerns with the current implementation which made me state that Group Replication was not quite ready yet.
(https://www.slideshare.net/Grypyrg/my-sql-group-replication)
(Un)lucky as I was, a large part of the attendees were Oracle developers and the months after this, many of these bugs and missing features were implemented in both MySQL 8.0 as well as backported to MySQL 5.7. (Thank you!)
This is a followup presentation on my previous analysis, where I will look into the changes since and re-evaluate the readiness of Group Replication for production usage and provide my insights and opinion on the state of GR.

"Serverless" can have different meanings. But regardless of what anyone says, one thing is clear: there are many servers behind it! The goal of this presentation will be to understand when, how, and why to adopt serverless technologies. To do that, we will observe the three pillars of serverless: event-driven, micro-billing, and self-scaling abstract infrastructure, and on top of that we will look into the expected developer experience and how it will positively impact developers' productivity. Lastly, let's take a look at some architectural patterns that can help you initially adopt the technology for brand new projects as well as into existing systems.
A Look Back at Enterprise Integration Patterns and Their Use into Today's Ser...Bruno Borges
Functions, and the so called serverless computing have freed deveopers from worring about infrastructure, and even upper platform layers, as well some steps in the software development lifecycle. But once you have functions deployed, how do they interact with each other? How message navigates between them? Maybe, just maybe, it’s time to look back again at EIPs - Enterprise Integration Patterns, and their use in this new way of deploying code to the Cloud. This talk will cover primarily the use of one of the key EIP frameworks - Apache Camel - and top patterns applicable to Serverless Computing using Functions services by Cloud vendors as part of the demonstrations.
Java SE is ideal for building lightweight microservices and those services are increasingly being deployed to the cloud. Cloud platforms are attractive deployment targets due to their high availability, affordability, ease of management, and access to services like object storage, messaging, and databases. And when well architected, Cloud Java apps exhibit a number of qualities like portability, updatability, configurability, composability, and scalability.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

One of the big aspects of WebLogic Server 12c of course is the arrival of Java EE 6 support. Java EE 6 is a significant update for developers using WebLogic Server as it results in building applications that require less code (upwards of 50% in some applications), fewer Java classes (in a typical application we have seen upwards of 25% less classes) and dramatically reduced amount of configuration via XML. Bottom line: it is significantly faster to build applications and the applications are simpler to maintain. Java EE 6 also introduces common Java productivity practices that frequently were in proprietary frameworks that had to be installed, upgraded and maintained separately. Now common practices like dependency injection, annotations are part of the base container – common across all Java EE 6 implementations. Further, the model of modern programming with transactional POJOs for business logic and RESTful interfaces for Web and mobile applications are part of the platform. The modern programming paradigm is now native to the container: Servlet 3.0 with Java Server Faces on the front end, transactional POJO with EJB 3.1, simplified resource injection with CDI (dependency injection) – no third parties or additional frameworks needed.Finally, beyond innovations right from the core standard on which the server itself is built on, a signifcant amount of work has been done with Maven to bring what are de facto industry practices with open source dependency management frameworks like Maven, build environments like Hudson and popular development environments like Jdeveloper, NetBeans and Eclipse. Specifically in WebLogic 12c we have a set of Maven goals and functions, including: install, execute WLST scripts, appc support, deployment, server lifecycle (start/stop) and even domain creation. This makes not only the usage of Maven for dependency management but also part of a simplified build, test and tear down cycle incredibly easy.
Transaction Guard and App Continuity - Transaction Guard = the protocol coming back to the app server to allow decision making about what the client should do - Application Continuity is the result that happens – no interruption in service because we take thoughtful action like appropriate JDBC replayDBMS Resident Connection Pools (DRCP)- Every app server, each with connection pool (real connections underneath)- 1000 servers each with connection pools 100 pool size = 100000 connectionsReality – 1000 connections. Virtual connection on DB connecting- Built into UCP- What DRCP does is virtualize at the DB level all the connections Pluggable DBEach tenant out of the pool identifies themselves (DB sets principal –”tagged”). VPD on steroids. Two things seemed to be helped:1. Effectively lets customers upgrade their DB transparently to later versions within the context of a single DB container; 2. Let’s customers run multiple versions of DB (tenant DBs) inside a DB container. more efficient (CPU and disk) easier to secure easier to upgrade3. Single data source can provide MT access to the appropriate DB by switching DBs
