Distinguished principal software engineer. I love #cybersecurity, #Linux, #BSD, #KaliLinux, #RetroComputing, #RetroCoding, #RISC_OS, #AmigaOS, #AtariST & #8bit
This weekend I finally found some time to add multi-sentence line support and finish the Transpiling Framework for my #UltimaVM, a fast and secure bytecode interpreter for #Linux, #Windows, #macOS, #BSD, and #RISC_OS.

In a recent thread on here folks were talking about how useless is #RISC_OS Apps facility. Guys, let me remind that is a thing of the past. We have !Launchpad by years now that fully replace Acorn Apps (even on the old Archimedes) and gives all RO systems same features as macOS and Win 11 Launchpads

Ok friends, I declare the best time of the year is officially open! 😂 🎃 - Thanks to my GF and Mr. Kipling

And while on the @riscosopen.bsky.social forum people are posting of using Linux, no resurrect RISCOSE, no something else, no nothing is possible for #RISC_OS is the typical old school mindset, #ProjectMerlin runs now on #AArch64, because if we don't start doing something, nothing will ever happen.

Oh boy! Well let's see if Meta AI actually understand how RISC OS BBC BASIC actually works...

This weekend #ProjectMerlin got support for #Linux Boot Protocol, so now it should work happly with #UBoot and things like #QEMU -kernel when the LBP is activated as a feature at build time. For now it can be tested only on the Pi 2, but as soon as I have time I'll extend it to all other platforms

Completed support for Live Source Code level Debugging in #VSCode. This works with both QEMU and real Hardware (Rpi). I am also working with ARM debugger developers team to ensure ARM Debugger works reliably with Merlin (and yes this is uber cool!). 👇

This weekend I forgot to post about the progresses on project #MerlinOS, sorry it has been a busy weekend. However lots of things, so check the thread for details, here is the current progress: 👇

A note on my #UltimaVM for #RISC_OS users: when coding on Ultima, we don't care at all about RO multistasking, we just code like on Windows, Linux or macOS. If we want to run an Ultima App in the desktop we just use the `--mt` option in the command line, everything else is handled by Ultima itself:👇

This weekend I had some time to continue working on Project Merlin, so progress tracking update!:

Website is finally live! riscoscommunity.org
Works with all #RISC_OS browsers down to !Browse (yep you've heard it!) and expect a bunch of really cool services coming up in the next few months, enjoy! 😎

May 27, 2025 at 9:29 AM
And today #Wordpress plugin to get #RISC_OS Community
#GithubProjects
updates on retro browsers! GitHub starting to work on IE4 basically!😎
May 26, 2025 at 5:33 PM
Retro web browsing the modern way! Almost completed a set of plugins and themes to transform the latest #WordPress into a retro browsing platform including an MPEG-1 encoder to watch videos! Behold latest WP on NetSurf and #RISC_OS !Browse! 😎

A blurry picture that shows a brand new Acorn / #RISC_OS ShareFS/Access+ reverse engineered protocol and written in Rust for Apple macOS, Windows, Linux and BSD to have native file sharing with RISC OS without any problems. I hope to finish it for the London Show this autumn:

#RISC_OS happy and very stable under some call stack trashing tests. The test suite is growing, yet good olde RO remains stable and highly resilient to mistreatments and security hacks like never before, thanks to UltimaVM abstraction layer! Even when these tests are ran in fragile Task Win😎

It's been 40 years I waited for this, but I can finally say, using UltimaVM on top of RO makes #RISC_OS actually modern! None of these naugthy tests even makes RISC OS blink an eye (and with UltimaVM task Scheduler not even freeze the desktop while running)! 😍
March 2, 2025 at 2:07 PM
And at 5:47am on a long coding session night/morning, UltimaASM for #UltimaVM was promoted to Macro Assembler! 😍 #RISC_OS can make it lol Next, the Macro ASM has to be promoted to OOP ASM (Object Orientated ASM):

And Boom!💥 The new AI Assistant reached already more than 50 users on just one day of "life"! :)
Thanks everyone for taking part in this and for being in favor of innovation on our good olde RISC OS 💕
(While previous AI Assistant is reaching almost 300+ Users!!!!)

For all international users: Through these AIs you can now interact and use both the RISC OS and the BBC BASIC User guides in your own native language, here is an example in Italian:

#RISC_OS Added automatic disassembly for bytecode addresses that generated an exception in UltimaVM! Knowns the module, the address and thread/task. Nice touch it also disassemble the relative label is present and adds useful columns description, this below the error message:

A bit late to post this on Iconbar! So the #risc_os Advent 2024 goes on socials! Happy Holidays, all! Here's a sneak peek at the progress on UltimaVM, a fast bytecode interpreter and unified API for RISC OS 26, 32, and future 64bit, as well as other OSes and architectures!
