Significant `HashMap.putAll` improvement by adding a fast path for a couple of common cases.

Would you be interested if JetBrains releases a totally local AI agent, working 100% on your laptop, using our code insight engine and deeply integrated into the IDE? Yes, it will be probably 1 month behind the very recent frontier models, but no token blood bath anymore WDYT?

One JEP worth revisiting: JEP 485 in JDK 24. It introduced gather(...) to streams, a new intermediate operation for transformations that do not fit neatly into map, filter, or flatMap. Tiny example šŸ‘‡

This is a bit serious. I really need your feedback. Long story short, I think Ethernet is a relic of the past and should be confined to walls and floors. Modern laptops and many devices are moving away from it in favor of Wi-Fi, which isn’t always convenient and ends up requiring adapters and dongles on desks. So I thought, what if we made a router with USB ports that essentially act as USB-to-Ethernet adapters inside the router? In my personal experience, this would be super cool for certain use cases. For example, at a conference booth, WiFi or Ethernet could be used as an uplink to the router. And the router could have a VPN set up to the company network. For a HomeLab, this is a pretty neat setup as a demo stand. And it would work just fine as a travel router, too. Would you like to see a device like this come to life? This could very well be the first hardware product from developers, made for developers. I mean, from JetBrains. On the technical side, I have some rough ideas for features and unique capabilities. For example, automatic detection of the WAN port regardless of where you plug in the network (the device has 2 Ethernet ports). I’d be happy to dive into the details in the near future. I’d appreciate it if you shared this post - if only because it adds a bit of variety to your feed, which I’m sure is full of AI content and news about AI, offering something tangible and practical.

Replying to @zanehkoch
When I was on the ISS for my nearly year long mission, there was a telomere experiment comparing my telomeres to my earth baseline and my twin brother as a control. Hypothesis was they would get damaged and worse due to the environment. Turns out they got better. Initially NASA thought maybe it was due to exercise and diet. After I returned we learned JAXA had a telomere experiment on some small worms the same time I was there. Their telomeres got better too. Never saw the worms doing any exercise. After further study determined it was the radiation.

Big day for @Java – Java 26 is here! ā˜• IntelliJ IDEA already supports it, so you can try the new features right away. Read more in our blog post: jb.gg/avyjks. Visiting @JavaOne? Stop by the @JetBrains booth to talk about Java 26 and IntelliJ IDEA with us in person.

Quarter-century of IntelliJ IDEA. I made a small archive repo for the earliest versions, and the best part is the screenshots: github.com/CrazyCoder/intell… Sharing in case anyone else enjoys digging through old software. #intellijidea #jetbrains

Great to see @jetbrains get serious about Wayland. Their suite of IDEs have been made to work in Omarchy with a plethora of window rules and hacks, but would be great if everything was just right out of the box. So excited to see this! alternativeto.net/news/2026/…
