So we continue to have guests in our show to talk to us about interesting things... This time is about Apache Tika. This is an incredible tool to do search file processing and metadata extraction. Think about that you have tons of unstructured
We have a great time talking to Matt Topol from Voltron Data on one of his Apache Software Foundation projects called Apache Arrow. It's both a spec and implementation of a columnar data format that is not only efficient, but cross-language com
Ok, so it's an incredible time to be in the Java Ecosystem, and one of the biggest frameworks out there just dropped their three-point-oh version! That's right! So Spring Boot is not officially 3.0, and it has as a Baseline Java 17! (oohh!!). S
Whew! So we took a big break over summer (like Bob said, we were just swamped with work.. oof), but we are BACK! and like always we are ready to explore even deeper Java topics for the professional developer. This time we set our sights in Apac
Yeah! so we have been working with the cloud for a while, terms like K8s, EC2, Route53, BlobData, CLI has been swinged around... and is a little mysterious, and sometimes looks like a black box where you just click buttons, add things, type com
Ok, so is time to talk about something secretive! Like API Passwords, Auth tokens, or keys... these are things that we want to have as a Secret within our microservice. And yeah, adding them into your source code is a big no-no Here we cover th
So is time to celebrate! We got a new box of toys with the new release of Java! This is also a Long-Term-Support release which means that's usually a "good one" to jump into! Switch Expressions! Helpful Nullpointers, Sealed Classes... there is
So while Java is the "main" language of the JVM, it is by no means the "only" language. And one of the purely functional programming languages is getting a new facelift! Scala has been going through a revamp on the syntax and the features, and
You'll run it everywhere there's a production system. Some kind of Metrics collector like Statsd or InfluxDB. They work like magic, reporting on the health of your application. but how does it really happen? We dive in on how these Application
So we had a previous episode where we show a party trick with GraalVM, where we saw how to create a Native Image. It was really the "hello world" of Native image creation, so Bob decided that's not good enough! In this epidose we dive a little
So it happens. Sometimes a Java program just "dies" with the dreaded Out-of-memory Exception. Sometimes, it leaves behind a "heap dump", or a copy of what the Java program had in memory when just before it throw the Out-of-memory exception. For
We're back! and now we move to the new-fangled serialization and deserialization frameworks, starting with Protobufs! Google's contribution to the serialization space, Protobuf V3 makes it easy to create a very efficient on-the-wire serialized
Ah, Serialization... the bane of every Java Developer! If you are still using ObjectOutputStream, and Serializable, then you do want to listen to this episode! We move past the objectoutputstreams to what most people are running into these days
So just in case you didn't know, but being a Java developer is as fun as ever! The ecosystem has been changing from the past year, and today, we have "tons" of Java Developer Kits to choose from. Want to know what happened? And want to know how
Java 14 is out! And with it, we now have a preview of Java Records! We go over this newfangled feature... and get this... we finally did it! We actually recorded our first Video Podcast (Woohoo!). A great episode Number as well (episode 90) to
You heard it going around, everybody is talking about Kubernetes, and Minikube, when using Docker, and CLI. It's like a foreign language! While we know Java very well, with the advent of Devops, we are supposed to be Deployers, and Scalability
One of the first things that you learn to appreciate when you transition programming from hobby to a way of life is to find a good way to troubleshoot problems. Most of the time this means logging and monitoring, so for this episode we decided
It's that Streaming-new-deal that has been taken over the web world, Reactive! You've heard about it, and maybe even tried to learn it a couple of times but find it confusing? Well, be confused no more since on this episode Bob and I explore th
Oh my! This episode is going to be one of our favorites. There are times where the Java ecosystem delivers something incredibly interesting (InvokeDynamic, Lambdas, Streams, Kotlin), and this episode is one of those! You may have heard it menti
There are technologies that sometimes are forgotten in a lonely corner, but that actually are quite sturdy. One of these is the All-Powerful Java Management Extensions (also known as JMX). With JMX you can actually expose a lot of metrics of yo
So you get that project that needs to connect to a server that doesn't talk rest, or http(s), but has its own protocol (or maybe it DOES talk https but you are looking for incredible performance!). Well, look no further than Netty! Sure, sure,
You got your new project, it's a brand new service, and is ready to go! But... have you done a health check endpoint for your app? In this day and age of microservices with auto-remediation and auto-scaling, having a well-behaved, functioning h
So the internet is all raging about this (not so little) framework that is doing it all. Created with a "cloud-first" mentality, @Micronautfw is aiming to be your next Spring Boot! And, oh gosh, how easy they are making it. We dive into what ma
Ah, Project Lombok is one of those little gems in the Java Ecosystem. But it's interestingly controversial! Some will love it (as I do), others will hate it! But no matter which camp you land on, you should at least know about it! Project Lombo
Nothing like a cold chilly day to stay inside and program some more. Before you start that new project from scratch, let's go over a pretty cool feature of Maven. Maven Archetypes! Learn how to create "project templates" for your new maven proj
