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

January 1, 2022 Freddy Guime Apache, Cloud, Frameworks, Libraries, Microservices, Spring

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 of best practices for it.

If you are building a non-trivial (or interesting) web service, this is a must-listen episode!

Episode 93. Not your Grandpa’s Serialization Part DEUX!

November 9, 2020 Freddy Guime Apache, Frameworks, Libraries, Performance

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 representation of objects, and then some. With the ability to have both backwards and forward compatible changes, protobufs is a great choice for transmitting information across services.

But not to be outdone, @BobPaulin goes in and covers Thrift, which goes a step beyond than just serializing messages, but also takes care of the “Transport layer”, adding the ability of doing Remote-procedure-calls! Imagine if instead of saying “I need to send a message to that service, and then the service can process it and send info back”, you just said. “I want to call a method on that service with this parameters and get the results”. Thrift exposes that functionality by letting you have an interface that you can just call in your client service, and it “magically” coordinates all the gnarly stuff to encode, transmit, execute, decode, and present your call. You don’t even have to think (too deeply) about how it all happens. As long as you define your thrift objects, thrift methods, and Thrift transport, the framework will let you just think of methods to call! that’s it!

So in all, a very fun episode where we discover what the new types of serialization frameworks are up to. If you ever had to create a message, or ever had to annotate an object as Serializable, then do take a listen to this episode!

Episode 88. Logging! (An Interview w/Renaud from DataDog)

January 23, 2020 Freddy Guime Apache, Beginner, Frameworks, Guest, Libraries, Tools 1:13:41

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 to interview Renaud Boutet who is DataDog’s VP of Product Manager, and don’t worry, he’s really a developer that went to the “Management” (i.e. dark) side, so he knows what he’s talking about!

Diving into topics from Logging Frameworks, to MDC, to a discussion of the three pillars of observability (Metrics, Traces, and Logs), this episode have good advice for everyone. From your first System.out.println (“I’m here”) to your slf4j with MDC setup, you’ll sure learn new tips and tricks!

Episode 79. Here’s a present to you! A library that makes you program less (Apache Commons)

January 6, 2019 Freddy Guime Apache, Frameworks 0:56:45

So for our new episode we decided to give YOU a holiday gift! Apache Commons! We covered one of the libraries that is ubiquotous in anyone who programs Java, but that not many know how robust and complete it is!

Do you have to do things like averages, min, max? Or do you have to read CSV files? What about measuring pieces of code with currentTimeMillis? or creating deep copy of Bean objects? Well, these and much more are already supported in the slew of Apache Commons project (and subprojects!). They usually have no transitive dependencies either so they are “ready” for the taking. And because Apache Commons is already used in many open source libraries, chances are that is already in your own project! Making it an easy thing to just start using it.

Happy holidays, enjoy this little gift from all of us :).

Episode 66. Ok, how about consuming Rest services

August 16, 2017 Freddy Guime Apache, Microservices, Spring 00:49:36

So we talked about how to create a rest service (using things like Apache CXF and Spring MVC), but sometimes, we actually need to consume these rest services. Luckily within the Java ecosystem there is a lot of way to skin that cat, and in today’s episode we at least cover 4 ways of doing so (including my favorite of the day, Feign). Come take a listen as we dive into Appache HttpComponents, Apache CXF with JaxRS, Spring RestTemplate and Netflix Feign on this fully-loaded episode.

Episode 65. Oh my gosh, we missed CACHING! (what a cache miss!)

July 6, 2017 Freddy Guime Apache, Performance 00:55:55

What a strange omission, of all the concepts, one that all of us should always have is Caching. We have used it (and most likely we have been burned by it). Come and take a listen on how to correctly (or at least not as incorrectly) think about caching, finding out your “game plan”, and using JSR-107, or Hazelcast, or Apache Ignite or Spring. LRU? Time-based? How much memory? Long distribution tails? cacheable keys? All concepts that you should ask before creating/using a cache!

Episode 62. Hm, what’s the best to travel this holiday? on Apache CAMEL, of course!

January 6, 2017 Freddy Guime Apache, Frameworks 00:52:56

So let’s talk about one of (if not the) largest, and most interesting framework hosted at Apache. Camel is essentially an implementation of the Enterprise Integration Patterns (EIP) book (which is a mandatory read for the serious dev!). It has so many contributions (and connections) that there is almost no popular system that it can’t connect to. In this episode we dive into the reasoning and “spirit” of Camel, to make sense on how to use it. If you ever used Camel, or have run into camel and scratched your head, then definitively take a listen!

 


A Big Thanks to LaunchDarkly for sponsoring our podcast! Feature flagging is easy, feature flag management is hard. What LaunchDarkly has done is essentially take a system like Google or Facebook has made in-house and bring this to the masses. With features like percentage rollouts, audit logging, and flag statuses, teams have complete control over features at scale. When you effectively separate business logic from code, you can build better software, faster without the risk

Episode 46. I’ve got ANTs in my build!

December 19, 2014 Freddy Guime Apache, Tools 0:58:12

It’s old, but as build tools go you will find apache Ant everywhere. Here we talk on how ant works and explore the build file. While it looks weird, there is nothing to fear! By the end of the episode you will be on your way to tackle any ANT build that have ever been thrown at you!
