I’m not saying that rewriting he backend is a good choice, but for me specifically, I’d like Lemmy to be written in Java. Why? I’m a Java software engineer for nearly 7 years now and I’d like to contribute. Yes, I could learn Rust, like I did learn Go, C, C++ and other languages during my cs studies. But I really don’t have the free time and motivation to do that after I already worked 8-10 hours at my computer. If I could use my existing Java knowledge to quickly fix some small bugs or whatever, I’d love to do that. But the hurdle to learn a new language (including other paradigms and best practices) just to contribute to this one project is just too high for me.
My PC has a i7-4790k overclocked to 4.5 GHz. It runs smoothly since I got it when it came out and it is still not a bottleneck in any of the games I play. But if I wanted to upgrade to Windows 11 I would need to buy a new CPU, new main board and new RAM, and it would not improve my gaming experience at all. It was my last machine running windows which I changed to Linux 2 months ago and I haven’t looked back.
