So, to add file associations, we need to be able to pass both the .properties file and the --file-associations option. At the time of writing this article, the org.jetbrains.compose plugin doesn't provide such a mechanism. There is an open issue on GitHub that describes a possible workaround, which, unfortunately seems to not work on macOS.
Lots of new frontend frameworks have been built on top of Rust, including Leptos, which happens to be one of the most popular ones. In this guide, we'll highlight why and how to migrate your JavaScript frontend to use the Leptos Rust frontend framework.
Project mention: Spark – A web micro framework for Java and Kotlin | news.ycombinator.com | 2024-02-10It's actively maintained with full time developers, performant, supports Kotlin out of the box, and has more features?
Meanwhile, if you're building something smaller than Netflix, I'm writing a book just for that (https://opinionatedlaunch.com/).
It's about mobile apps, but I talk about backend at great length, especially since my background is Java. The book is called "opinionated" because I cover Quarkus (https://quarkus.io/), monolith, Fly.io, and no K8s.
Kotlin also has a construct for asynchronous collections/streams. Kotlin's version of AsyncSequence is called a Flow. Just as Swift's AsyncSequence builds upon prior experience with RxSwift and Combine, Kotlin's Flow APIs build upon earlier stream/collection APIs in the JVM ecosystem: Java's RxJava, Java8 Streams, Project Reactor, and Scala's Akka.
Storing the notes: For storing the notes, we will use the amazing WatermelonDB package which is a popular sqlite wrapper for react-native. Instead of using the default package we will use a fork of this that uses sqlcipher instead of the regular sqlite, allowing us to encrypt the database by passing a secret key.
NgRx is the standard library for state management in Angular applications. With NgRx v14, many of the complex APIs following the Redux pattern have been greatly simplified. For example, ActionGroups make it easier to define new actions. However, the use of the Redux pattern is by no means easy and discourages many developers.
I’ve successfully worked on projects using an asynchronous event-driven way of connecting services. I really like the decoupling of business logic and the events triggering it. I highly recommend https://github.com/ThreeDotsLabs/watermill to be more flexible when it comes to choosing the actual technology driving the async patter. It might be NATS today but requirements might change and you need to change. Watermill prepares you for this.
Project mention: Redis Cluster with heavy write application results in bad redis read latency | /r/redis | 2023-06-05I am using lettuce java library with async api. They says it used pipelining as default. Also I tried manually command flushing. I don't see the improvement.
Project mention: Potential of the Julia programming language for high energy physics computing | news.ycombinator.com | 2023-12-04I thought that notebook based development and package based development were diametrically opposed in the past, but Pluto.jl notebooks have changed my mind about this.
A Pluto.jl notebook is a human readable Julia source file. The Pluto.jl package is itself developed via Pluto.jl notebooks.
https://github.com/fonsp/Pluto.jl
Also, the VSCode Julia plugin tooling has really expanded in functionality and usability for me in the past year. The integrated debugging took some work to setup, but is fast enough to drop into a local frame.
https://code.visualstudio.com/docs/languages/julia
Julia is the first language I have achieved full life cycle integration between exploratory code to sharable package. It even runs quite well on my Android. 2023 is the first year I was able to solve a differential equation or render a 3D surface from a calculated mesh with the hardware in my pocket.
Project mention: Is it wrong to use "try-catch" inside a reactive stream operator (project reactor)? | /r/learnprogramming | 2023-12-10I was exploring reactive streams with project reactor and I encountered a use case where I needed to skip to the next event if an error occurred during the processing of the current event (e.g. deserialization issue).
akka.net actors. Actors all the way! https://getakka.net
In its docs, Astro recommends nanostores, but I’ve used effector in the past. And LOVED IT. So I’ve used it for this project as well.
AsyncAPI: Interested in how to define your WebSocket APIs? One of the most advanced realtime specifications is the AsyncAPI specification, which comes with various generators for code and documentation, as well as renderers for the specifications.
