A Java geek

diceroller, a sample Rust project

This is the 8th post in the Start Rust focus series. For me, the best learning process is switching regularly between learning and doing, theory and practice. The last post was research, hence, this one will be coding. I’ve been a player of Role-Playing Games since I’m 11. Of course, I’ve played Dungeons & Dragons (mainly the so-called Advanced Edition) but after a few years, I’ve taken upon Champions and its HERO system.

Rust and the JVM

This is the 7th post in the Start Rust focus series. So far, we have learned the basics of Rust syntax, developed a custom Kubernetes controller, and integrated with the front-end with Wasm. I’ve been using the JVM for two decades now, mainly in Java. The JVM is an amazing piece of technology. IMHO, its biggest benefit is its ability to adapt the native code to the current workload; if the workload changes and the native code is not optimal, it will recompile the bytecode accordingly again.

A Rust controller for Kubernetes

This is the 6th post in the Start Rust focus series. To teach myself Kubernetes in general and controllers in particular, I previously developed one in Java. This week, I decide to do the same in Rust by following the same steps I did. The guiding principle is the creation of a Kubernetes controller that watches pods' lifecycle and 'binds' a sidecar to them. When the main pod is scheduled, the controller schedules the sidecar; when it’s deleted, it deletes it as well.

Rust on the front-end

This is the 5th post in the Start Rust focus series. Up until now, JavaScript has been the only ubiquitous language available in browsers. It has made JavaScript much more popular than its design (and its associated flaws) would have allowed. I don’t want to start a holy war about the merits of JavaScript, but IMHO, it only survived this far because of its role in browsers.

The Rustlings exercises - part 2

This is the 4th post in the Start Rust focus series. Last week, I started the Rustlings series of exercises. Now is the time to finish it.

Java

BlockHound: how it works

One of the talks in my current portfolio is Migrating from Imperative to Reactive. The talk is based on a demo migrating from Spring WebMVC to Spring WebFlux in a step-by-step approach. One of the steps involves installing BlockHound: it allows to check whether a blocking call occurs in a thread it shouldn’t happen and throws an exception at runtime when it happens. I’ve presented this talk several times in the previous week, both in its Java version and its Kotlin one.

The Rustlings exercises - part 1

This is the 3rd post in the Start Rust focus series. To continue building my understanding of Rust, I searched for some simple Rust exercises. Hence, I dedicated my weekly personal work time to the Rustling exercises. There will be two posts dedicated to Rustlings. The reason for that is that it contains many (many!) exercises. Besides, I need to learn about the more advanced themes such as threading.

My second cup of Rust

This is the 2nd post in the Start Rust focus series. Last week, I drank my first cup of Rust. I learned concepts that are foreign in the languages I know: ownership, borrowing and lifetimes. This week I want to drink the second cup and see where it leads me.

My first cup of Rust

This is the 1st post in the Start Rust focus series. It all started with an informal chat with my friend Anthony. We were talking about languages, and I said that I preferred compiled ones. He then went on to mention Rust. We admitted that we were too afraid to learn it because of its perceived complexity. After the chat, I thought about it, and I wondered why I didn’t check by myself. I did. And I became interested.
