And this seems appropriate time to mention/ask a question of getting openCL for similar for Pi's GPU... I have some doubts it would be able to compete with nVidia's GPU, but it would be nice to have some feel how close they are...

... Is it possible to write code like that in Rust in such a way that a mathematician with no experience of coding could read and have some idea what the algorithm used was? Its not good if arcane tweaks are required all the time to get performance. I don't think people who designed Rust had readab...

It clearly says there that you are still using the "stable release channel". I don't have a Pi nearby to test on but I tried it on my Jetson Nano which is running 64 bit Ubuntu. ... BUT, I had to remove one test that used SSE instructions. It was horribly complex and slow as hell so good riddance t...

Hm. All my rust plays were on Pi4, 8GB on 64bit PiOS (hence Eclipse).

... memory handling of Rust seems just 'standard', well known, common sense stuff... That is a surprising statement to me. I have never seen any other programming language with the approach to memory that Rust has. What with it's rules about multiple aliases to variables, the "borrow checker", no g...

I can see so many different concepts meeting in Rust: strong typing; compilation to fast, c-alike low level; functional style and innovative memory handling (at compiler level - memory handling of Rust seems just 'standard', well known, common sense stuff) and such... That functional style code, in ...

I have never been into Eclipse much. It always seemed so big, slow and complicated when I have had to use it on various projects. But this looks pretty cool. I've lived through rise and fall of Eclipse and how people slated it while alternatives weren't any better... Now, I appreciate it even more ...

BTW I had similar question only a few days ago (but I'm fine to use dd from command line). Anyway - is it worth adding line somewhere on https://www.raspberrypi.org/downloads/ just to avoid further confusion? Re support for ARM: it all boils down to what is really needed. I've sorted out all my cand...

Great news: Lwjgl3 is now working on RPi! :D I've updated head of rpi-1.9.11-SNAPSHOT branch (1.9.11.rpi-SNAPSHOT version of gdx artifacts from https://raw.githubusercontent.com/natdan/libgdx/mvn-repo repository - see example project from here: https://github.com/natdan/rpi-libgdx-example) to the la...

I've made a short write up what (and how?) I've done here: https://blog.abstracthorizon.org/posts/ ... -64bit-os/

Also, there's (not to be treated as so permanent) link to 64bit eclipse - eclipse-java-2020-03-v1-R-linux-gtk-aarch64.tar.gz

Does rpos/64 already have support for boot from usb on the pi4, or do we still have to manually copy special elf/dat files to the boot folder?

No need to copy elf/dat files. 64bit version image boots without issue from USB.

https://www.raspberrypi.org/forums/download/file.php?mode=view&id=37597 It is on beta 64bit Raspberry Pi OS and quite a handcrafted version (from the latest available to download for x86_64 + top of the repo builds for aarch substitutes).

Android Studio and Eclipse are the best Intellisense IDE for the java programming That's not 100% true - Intellij's Idea is slightly better - but Eclipse is better for CPU/memory starved systems (as Raspberry Pi is). And we might have Android Studio back on Raspbarry Pi again. Maybe? :) https://www...

Maybe not the feedback that directly helps with developing of 64bit version of Rasbian OS but still (somehow) positive one - Eclipse is finally back on Raspberry Pi (and it works faster than IntelliJ's Idea): https://www.raspberrypi.org/forums/download/file.php?mode=view&id=37597 I wasn't easy - nor...

I don't know if this is supposed to be support for when something is not going well or just for testimonials but here it is. My current setup is: pi4 with 8GB 1TB WD Blue SSD with some generic JMicron USB addapter and beta 64bit image (adopted to use only 32GB for partition + another 32GB primary an...

That seems quite interesting! Could you, please, in a few short sentences describe Boof? Yes, I did go to the web site and picked up a few things but still not quite sure what I feel about it. For instance: 1. Is it Java only or is it lower level stuff with bindings for different languages, too (asi...

Yep I came here to find the link for compiling, then I thought I would try an install. I noticed Blender was pre-installed, maybe??? OpenSCAD, Wings3D, Inkscape... yep all working. That's great!

Pi4 8GB + SSD (and USB3 case) ordered - all in preparation (and anticipation) of switching to 64bit Raspbian!

Thanks for letting us know. I was just thinking of needing to recompile it again as I did it for regular (32bit) Raspbian.

Hi all,

Does anyone know if is there any pre-build Android build tools version for armhf (except 6 years old https://github.com/skyleecm/android-build-tools-for-arm)? Or how to make my own?

I've got gradle android app which I would like to be able to build on RPi4 (no 64bit version of OS, sorry)...

Down the similar path - you can use this (http://remotevm.abstracthorizon.org/source.html - I promise to 'modernise' it these days) - you can push your code from development machine to RPi and execute it 'remotely' (along with reading stdout back in your IDE's console)... Do ask if you need more hel...

RPi3b+ might be a bit tight for developing java on it. RPi4 (with 4GB of memory and fast storage like SSD) is more like it. IntelliJ works perfectly well. Eclipse, unfortunately, switched 32bit support off, so there won't be anything else there... Also, picking up any other desktop/laptop and using ...
