The Istio course has been updated for Istio 1.5

06 Apr 2020

Istio 1.5 has resulted in some breaking changes - the old Pilot, Citadel, Galley control plane components have now been merged into a single component called Istiod.

The course has now been updated to reflect this.

A new video, called "Getting Istio Running (Updated for Istio 1.5)" has been added to the course.

The video called "Enabling mTLS Policies" has been updated to reflect the new 1.5 defaults.

A new video called "STRICT vs PERMISSIVE mTLS" has been added.

A new section called "Customizing Istio with Istioctl" has been added.

The old section on Installing (using Helm) has been marked as deprecated but we will leave it in place in case anyone needs it.

There is still one further video to add, but we are awaiting a bug fix to Istio before adding this - we will update when this is ready.

Kotlin with Spring Boot now available

29 Jun 2018

We have just released our latest course, covering the Kotlin programming language. Kotlin is a JVM language created by JetBrains - the company behind the IntelliJ IDE. It offers a number of enhancements over Java, including that it's less verbose, has immutable variables, and almost always gets rid of the NullPointerException. Java developers will find Kotlin a pleasure to use, and compared to some other JVM languages, it's an easy transition from Java to Kotlin.

In this course we learn the fundamentals of the Kotlin language, and how to use it to build Spring Boot applications with Kotlin.

Updates to the Microservice Deployment course

31 Mar 2018

EC2 instances now have an updated version of Ansible installed by default.

An Update to the AWS Course

28 Mar 2018

We've made an update to our Cloud Deployment with AWS Training course

Recent changes to the Tomcat which is installed by default on EC2 have meant that it is impossible to access the manager application without making some config changes.

We've added some extra material at around 51min40s to Chapter 2 of the course.

Thanks to all those who reported this problem - we're sorry if you got stuck here!

Login problems!

20 Mar 2018

We think the problems with our login module are now fixed - please do contact us if you have problems logging in, or if you don't have a secure https connection with the site.

Spark - Problems with NotSerializableExceptions?

13 Mar 2018

If, in the next chapter on "Mapping" (or any future chapters) you experience a NotSerializableException, it is because your CPU architecture is sophisticated enough for Spark to treat each CPU as a node in a cluster!

But this causes a crash with System.out.println (any functions run against an RDD have to be serializable in a multinode architecture).

We have added an update video to the course which describes the problem and a simple solution.

For more details check out the course page here.

Having an "Unsupported major.minor version" with Tomcat?

26 May 2017

Many of our courses that use the Tomcat web server were written with Java 7, and we include Tomcat versions 7 or 8 in the practicals and code files. Unfortunately these versions of Tomcat are not compatible with Java 8. If you try to deploy a WAR file built Java 8 to Tomcat 6.0, you're likely to get an exception which will look something like this:

java.lang.UnsupportedClassVersionError: com/package/myClass: Unsupported major.minor version 52.0

To get around this problem, you can either upgrade to Tomcat version 9 (which you can download from http://tomcat.apache.org/download-90.cgi) or you can compile your web application with Java 7 compliance. This second option is very easy to do - simply open your project properties (right click on the project folder and choose properties from the menu) and in the pop up window, select Java Compiler and change the "Compiler compliance level" from 1.8 to 1.7.

The first Virtual Pair Programmers podcast

19 May 2017

Trainers Matt and Richard have been debating recording a podcast for some time. Inspired by The Stack Exchange podcasts (that sadly finished in 2014) and The Java Posse (whose last podcast was 2 years ago), we think it's time for someone to come along and fill the gap, and so we've decided to give the challenge a go!

We discuss the current state of Java 9, and Jigsaw in particular, plus we touch on thymeleaf, JSF, and there's an update on what we're working on too.

The latest on Java 9... will it be delayed, features removed, or released with problems?

11 May 2017

In case you’ve not been following the progress of the next release of Java SE, Java 9, we thought we should let you know what the current status is (or at least our current understanding of it!).

As you might expect, the next version of Java will have some changes in it from the earlier versions. By far the biggest, is the introduction of Jigsaw, an API for building modular applications. Some have described this as a bigger change for Java than when generics were introduced back in Java 5.Read more

SHA-1 is broken... and it has now been proved

20 Mar 2017

This will be of relevance if you've done (or are interested in) our Spring Security series of training modules: it has long been known that SHA-1 is theoretically broken, but it has now been actually broken.

shattered.io shows how it is now possible to create two materially different files which generate the same SHA-1 hash.

Of particular note is that GitHub uses SHA-1 to generate names for every object you store; there's a commentary on how this affects them here.
