Currently I work on an implementation for authentication and authorization using Spring Boot, Spring Security, OAuth 2.0 and JSON Web Tokens (JWT). In order to get a good understanding on these topics I found several talks that I’m going to list here.
“100% Stateless with JWT (JSON Web Token)” by Hubert Sablonnière. I found it very useful to get a better understanding on using JWTs to create a really stateless authentication architecture.
There is another interesting talk on Stateless authentication with OAuth 2 and JWT by Alvaro Sanchez-Mariscal.
This post will be updated as I find new resources.
I’m interested in Apache Kafka Streams and would like share some information on this topic with you. There is a great talk about Stream Processing from Neha Narkhede who co-authored Apache Kafka and is currently a co-founder and Head of Engineering of Confluent.

Programming as Performance? This sounds interesting and indeed it is, as you can see in this video by Sam Aaron (a Post-Doc Researcher at the Cambridge University):

Assuming that your pdf is called “input.pdf” and consists only of one page. The above command colors any transparent background white.
In order to prepare and pass the Salesforce App Builder Exam I follow the learning path as described in the official “Certified Salesforce Platform App Builder Study Guide“.
But how many questions on each topic have to be answered in the exam? The total number of questions is 60 and the expected number of questions on each topic can easily be calculated:
Overview of exam questions per topic
|Business Logic and Process Automation||27%||16,2|
|Data Modeling and Management||20%||12|
My strategy is to begin with the most important topic with the most questions and work my way down to the end of the list.
This post is the beginning of a series of posts on how I prepared for the exam. This part gave an overview of the topics and their weights. In the next part of I will focus on “Business Logic and Process Automation” in Salesforce and go into more depth.
Stay tuned and stay focused!
