Episode 84. Let's get down and dirty w/Netty!

Release Date: 07/09/2019

Episode 104. It's all about Apache Tika, the project that lets you index EVERYTHING.

Java Pub House

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 files, like emails, or documents, and you want to extract, index and then search theses. This is Tika's purpose. And who best to walk us through how it does its magic that its Project Management Committee (PMC) Chair, Tim Allison! So take a listen as we go deeper on ingesting tons of content (which is fundamental for things like training LLMs)....

Episode 103. Let's share data cross-language with Apache Arrow! (among other things)

Java Pub House

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 compatible. We walk through the scenarios that it covers and how is becoming more and more pivotal for things like ML and LLMs. So come listen to this JPH episode on one of the best and free ways to distribute data and integrate services working on top of that data! http://www.javapubhouse.com/datadog We thank DataDogHQ for sponsoring this podcast episode ...

Episode 102. Oh my... Spring Boot 3 is out! An interview with Dan Vega from the Pivotal Team!

Java Pub House

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!!). So we brought in the big guns to talk about what does it mean to Upgrade to Spring Boot 3, and what are the new cool toys we can expect from that upgrade! In all, an amazing interview full of great things that are available NOW (so whatcha waiting for! Upgrade!) http://www.javapubhouse.com/datadog We thank DataDogHQ for sponsoring this podcast...

Episode 101. Allright, let's talk about Kafka

Java Pub House

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 Apache Kafka, one of the (if not THE) dominant distributed messaging framework / broker. If you have been integrating webservices, you might have been running into message brokers (and applying Enterprise Integration Patterns), well if so, you most likely have run into Kafka. We dive into "What does Kafka Solve", into what it is (and isn't), and why...

Episode 100. To the CLOUD... Which one? All of them!

Java Pub House

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 commands, until it finally something good happens. But if something bad happens, we tend not to have the slightest idea on why! Never fear, on this episode of PubHouse we start from the very beginning on describing (And dismantling) what the "Cloud" really is... Starting on how we got there, what are the different "components" of most clouds, and how to...

Episode 99. SHHH! It's a secret! (Storing API Keys / Passwords / tokens!)

Java Pub House

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 the dos (and dont's) of secret management, what are the benefits and drawbacks of the different solutions and we explore some of our favorite open source (and Cloud tools) for keeping secrets. We answer some important questions on how to effectively store and manage these secrets (the short answer is don't try to do it yourself!), and end up with the list...

Episode 98. It's HERE, FINALLY HERE! Java 17 LTS Release

Java Pub House

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 a TON that's new And we got the best Doctor in town to walk us through all of them. We're of course talking about Stuart Marks! (AKA Dr. Deprecator). We cover most of the important features from 11 to 17 (there's a ton that was left out, so keep following the links to know more!) http://www.javapubhouse.com/datadog We thank DataDogHQ for sponsoring this...

Episode 97. Hey there Scala 3! Looking good with those new Features!

Java Pub House

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 if you ever run into a scala user you know how passionate they are about their language! (hint: they love it!) So while we might be working in Java projects most of our time, it is a good time to revisit that developer toolbox and learn when and where to use it. And if anything else, having a dip into a fully functional programming language teaches any...

Episode 96. Watching Metrics w/Micrometer and Statsd

Java Pub House

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 Performance Management tools work and how do they really "see into" your application. We demistify all this magic, and actually describe how to add "new" metrics and how to publish it! If you ever worked in a production application, and were wondering how do these metrics get graphed and collected, well, wonder-no-more! We go deep into Micrometer (the...

Episode 95. Ludicruos speed! Practical GraalVM

Java Pub House

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 deeper on how to actually run your Restful Web service (or other app) natively, going through the exercise of debugging GraalVM builds including adding Maven plugins, finding out how to quelch the different reflection errors and how to deal with resources (and those pesky JNI / so libs). In all, this is more of actually a practical use of GraalVM, not...

More Episodes

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 could really spend time working with NIO.2 and creating your own sockets and all that jazz, but why? The Netty.io folks already did it, and by golly they created a library that's "blazingly fast".

So take a dive into this episode where we talk about the main netty concepts (like pipelines and handlers), and give you a tip or two as you embark down into protocol performance bliss. Netty has seen it all, and has been battle tested for a while now (Have you heard of Jetty? well, that has Netty under the hood), and best of all, we go over how to be "lazy" about it! Netty really implemented a lot of protocols, events, and stuff already (for example LengthFieldBasedFrameDecoder, ProtobufVarInt32FrameDecoder, SslHandler, WebSocket00FrameDecoder and much more!), so you don't have to be the wiser and implement things from scratch... chances are... Netty already has them (or at least will have the right tools to create your own thing).
