    Project mention: Excited for 2023! | dev.to | 2023-01-01

    Java seems to have gained a second wind in recent years, and the innovation in this ecosystem is speeding up. Java 20 and LTS release 21 are expected to happen this year. RIFE2, an actively-developed pure-Java web framework, has recently caught my attention. Like Javalin, it appears to be built on top of the successful Jetty server. I also started exploring FXGL for building games with Java. Lastly, as concerns over COVID-19 variants wane I expect an increase in Java developers participating in community events. For example, Chicago finally had its first in-person JConf event and the Chicago Java User Group (CJUG) is easing back into in-person events.

  • Orbit

    Orbit - Virtual actor framework for building distributed systems (by orbit)

    Project mention: Actor system for the JVM developed by Electronic Arts | news.ycombinator.com | 2022-04-28

    > I can't help but recoil from a "hello world" that pulls in an entire container ship of dependencies.

    Where do you see the list of dependencies? Seems to me to be the ones defined at https://github.com/orbit/orbit/blob/233956001f1206ccbfde72ef..., is that correct? Doesn't look like "an entire container ship" but maybe the NPM madness have ruined me.

    > Especially that we already have a perfectly good, battle-hardened, and relatively lightweight implementation of Actor model with Erlang / Elixir.

    Yeah, if you're already using Erland or Elixir, why don't you go with that instead? This seems to be for the JVM, so one could assume that the ones who want to use this, is already invested heavily in the JVM ecosystem (which as far as I know, EA is when it comes to backend servers).

  • apkupdater

    APKUpdater is an open source tool that simplifies the process of finding updates for your installed apps.

    Project mention: looking for apps that can update other apps | reddit.com/r/androidapps | 2022-06-24

    The problem: i have https://play.google.com/store/apps/details?id=com.aniplex.fategrandorder.en installed from apk because game is not available in my region, and i need to update it manually, which i want to avoid, there is apps that can update only whitelisted apps (https://github.com/rumboalla/apkupdater and https://github.com/hemker/apkgrabber), but this apps cannot automatically check for updates and install them in background with root or with a12 permission, so, my question is, is there apps like apkgrabber/apkupdater but with support for installing updates automatically in background?
