A/B Testing: Automate test setup and simplify result analysis. E-commerce: Use AI to generate synonyms for more relevant search results. Issue Tracker: Implement natural language search to find tickets more easily.

Sorry, this are only the categories. But i have actual products in mind.

In some products, certain AI features have become expected. If a product doesn’t include them, it risks losing customers, making it a net negative for the market. At this point, companies either invest in AI or risk falling behind.

Don't autoplay in a loop it's very annoying. With that gone, it will be fun. Remove drag and drop.

I can recommend jabba, especially jabbaw together with mvnw.

do you know https://www.jbang.dev/ ?

btw. installing "java" is now very easy, you just need to install jetbrains toolbox, from there install intellij community edition (1 click), which installs a jdk for you with (2-3 clicks), when it detects that you need one.

Funny, never made sense to me why we had that book. We had exactly that Schneider 286, that must be the source. My dad could give me a basic introduction, from there the book was a treasure trove.

My dad had that as a book, I loved it. I learned a lot from it. Later I learned that someone with experience could have propelled me forward much faster.

Recently, I’ve been working with Quarkus[1], the quarkus-qute[2] (a type-safe templating engine), and htmx. I found the experience quite positive. Quarkus offers lightning-fast compilation with a hot-reloading Maven wrapper (mvnw), making development seamless. Picking up qute was straightforward, and combining it with htmx, especially with qute’s #fragment support for htmx, felt like a natural fit.

I can confirm that. 10tb uncompressed, 3tb compressed in clickhouse, 60 billion Rows, queries are fast.

I even could make a Quarkus native build with graalvm on the machine.

Same here, everything just worked on their arm. Podman, fedora core os via terraform, mvnw, jabbaw Just checkout and run. Awsome experience.

Last year I built a balcony watering system using an 8x ESP32 relay system from Lilygo, paired with mini submersible pumps. To monitor plant health, I integrated MiFlora sensors over BLE. Managing minimum soil moisture and pump duration has been 'configured' by hosting a configuration files on Pastebin.

This year, I'm taking it a step further by developing a management front-end. Instead of the hacker GUI using Pastebin, I'm implementing an extra M5 Atom running MicroPython with a web GUI. This interface allows me to configure the sensors, visualize sensor data with charts, and send notifications via NTFY to my phone.

I am considering open-sourcing the project.

Dcevm is regularly released from JetBrains as part of their JDK. https://github.com/JetBrains/JetBrainsRuntime

Also with 'Java on Truffle' on GraalVM you can use enhanced class reloading https://www.graalvm.org/latest/reference-manual/java-on-truf...

I think hot code reloading did not look that good in a very long time.

Seeing more java postings recently. Maybe hacker news thinks java got it's mojo back?

You might then be interested in Fedora CoreOS, we use it with Hetzner cloud and real Hetzner root server with good success. (Also with ovh)
