Lofi model @ work

I had a presentation @FrOSCon 2019 wih the title Open Source: Nimmst du noch oder Gibst du schon? The conference was very interesting and this was my first time at the conference. You have a free entrance on Saturday and Sunday and there are a lot of super interesting state-of-the-art topics.

I published my slides here: http://bit.ly/31DagCJ and FrOSCon published my talk as video right here: http://bit.ly/FrOSCon2019DewantoVideo

So in the year of 2019 web development is entirely occupied by JavaScript or derivatives like TypeScript? Well, not entirely… One small village of indomitable Open Source Java developers still holds out against the invaders with the help of Java to JavaScript transpiler GWT (http://www.gwtproject.org) and J2CL (https://github.com/google/j2cl)
Here is my article about Java to JavaScript transpiler for beginners: http://bit.ly/WebJavaStory

I just published a story "The Most Precious Thing — The Time of Your Life". I realize that we can change things by investing time instead of money. Here is the story: http://bit.ly/TimeIsKing

After waiting a long time, Google has Open Sourced #J2CL (Java to Closure transpiler). This is great since #Java devs have an alternative to #JavaScript frameworks like #React, #Angular and #VueJS. Check out my article @heise Developer (in German):

Very interesting presentation in Amazon Event "From Mainframe to Microservices - Vanguard's Move to the Cloud". Following parts can be used as Migration Patterns:

Different ways of how to move from Mainframe to Microservices:
Re-hostReengineer RefactorRewriteBatch job migrationData analytics enablementData-driven augmentationRe-platform with Linux and JavaRepurchaseRetireCombination of all This presentation also shows the Cloud Data Architecture at Vanguard. Generally this is how we can build our own database for our micrsoservicew at the cloud and at the same time still use the data from DB2 mainframe on-premise as well. 
Advantages using this data architecture: Each microservice reads data from its own local database.DB2 mainframe database can still be used from other Host / Cobol batches.DB scalability Disadvantages: You cannot write to the database in case you have a network problem. There is an extension to this Cloud Data Architecture by using buffered write or asynch…
