The 2025 London Show is less than 3 weeks away... www.iconbar.com/articles/The... It's now less than 3 weeks to go until the 2025 London Show!

Only 20 days to the #RISC_OS London Show! And Next @RISCOSitory post about it: www.riscository.com/2025/zfp-sys...

'the hell? it's 4:36am... lol anyway, new UltimaVM PUSH/POP register range fast memory copy is done and there is also a little "twist" POP supports both strick LIFO (like the JVM) and natural order (like the ARM). Had to finish so late, because I had a hell of a busy day at work... Need some sleep!

The RISC OS London Show is now just under four weeks away! Preview from RISCOSitory - www.riscository.com/2025/london-...

Added #JVM Stack Operations mapping to my #UltimaVM (see link). But I am thinking of adding indirect adressing: PUSH.U64 [r0-r1] Push mem val from addr in r0 to addr in r1 PUSH.F32 [r0] Push val at mem addr in r0 tinyurl.com/JVMToUltimaVM #bytecode #VirtualMachine #Coding #Programming #VM #RISC_OS

I've been working on Ovation Pro to add extra scaling options to the picture proxy setting. For those who attended my @rougol.bsky.social talk, I explained the use of proxy images. Base/16, Base/32 & Base/64 now offer even smaller proxies, making for smaller document sizes. #OvationPro #RISC_OS #DTP

🚀 Big week for #theCROWler: v0.9.8 lands this weekend! - Post-processing per rule - Remote app distribution (GitHub deploy coming) - Search API + JDorking - Bug fixes & perf boosts - Docker deploy builds ( #Arm + #Intel / #AMD ) 🔗 github.com/pzaino/thecr... #Coding #CyberSecurity #ContentDiscovery

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

Just released BeebEm 4.21. This fixes a bug with the tape sound emulation introduced in 4.20, another bug in the installer, and makes some improvements to the VIA emulation. Download here: www.mkw.me.uk/beebem/

This beauty is fully repaired and upgraded now. Lots of fun doing it.

RISC OS users: I’ve just updated MetaSprite to work around a SpriteExtend bug concerning mouse pointer sprite palettes.

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.

Rougol September 2025 meeting on monday - Publishing with Ovation Pro www.iconbar.com/articles/Rou... The September 2025 Rougol meeting is on Monday 15th September with guest speaker Gavin Crawford.

@compiler-explorer.com is now running with a completely new storage mechanism in the back end. It's taken me quite a long time to get to the point where I felt confident enough to switch over to it and it seems like it's gone without a hitch. Details: xania.org/202509/cefs

What an absolute master piece! www.youtube.com/watch?v=oygI...

After seeing another paper started to circulate explaining some of the causes #GenAI #hallucinate, I thought it would be useful to publish an article I’ve been working on for a while about all the most common reasons #LLMs do: paolozaino.wordpress.com/2025/09/09/a... #AI #ArtificialIntelligence

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

The Acorn A3000 is back online! We've been busy fixing this classic machine. Our team meticulously worked to open it up, diagnose the faults, and get it working again. It’s always a thrill to see a piece of computing history restored. #Acorn #A3000 #RetroComputing #VintageTech #Restoration

A gazillion things I had to repair later, my Acorn A3020 now boots, has an HD, serial mouse works, and it’s going places.

BeebEm 4.20 is now available. Lots of new features and bug fixes, including: * FSD format disk images * Teletext adapter emulation * Disk and tape image icons * Tape and serial port emulation * Full screen mode bug fixes * Saved state files And lots more... Download here: www.mkw.me.uk/beebem/

I opened new release 0.9.6 for #TheCROWler, so please don't forget to submit your bug findings and open feature requests (via email is fine!) github.com/pzaino/thecr... #ContentDiscovery #Crawling #CyberSecurity #Security #Platform #Programming #SoftwareDevelopment #golang

I see people still confusing concurrent and parallel tasks, they are not the same. I think one source of "misinformation" is the original OS multitasking design, a timeshare of a single CPU. Probably that is what's confusing. The term MT used on books describing a concurrent tasks scheduler.

Good video from @davefarley77.bsky.social about vibe coding. I am extremely skeptical about vibe coding TBH, I cannot see an AI being able to produce code out of a "thin" spec, but even in the case it could, the nature of SWE and incrementalism will collide badly with the way current GenAI works.

A bit of a wasted afternoon, but I managed all this with two CM4001008s (and a completely unnecessary 256GB NVMe drive). #overkill #frugal #RISC_OS

Chat to Mark about all his Elite projects at the next ROUGOL meeting on Monday 18th August rougol.jellybaby.net/meetings/ind...

Please everyone, do NOT send me private messages. There is a bug in @bsky.app right now due to age verification. They forgot to allow us to disable private messages. So your messages won't be read. My apologies on behalf of the Bsky team who has still to catchup on the issue I think. #bsky #bug

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: 👇 riscoscommunity.org/projects/ris...

So fortunate to have spent my formative years learning how to code in Z80 (at home) and 6502 (at school/college) on two of the most successful 8-bit microprocessors ever made. Happy Birthday 6502!

Drag'n'Drop 14i4 edition reviewed www.iconbar.com/articles/Dra... The Summer edition of Drag'n'Drop magazine is now out (with a suitably loud cover).

Congratulations to the Lionesses 🏴󠁧󠁢󠁥󠁮󠁧󠁿 A demostration that real hard work, passion, and determination can lead to great achievements! www.theguardian.com/football/202...

Today's fun fact: Browsing the web on an Archimedes (real hardware, not emulated) with ArcWeb is very much still possible! (Bonus hat-tip to @actionretro.bsky.social for creating FrogFind to make pages usable on old systems!)

Not really buying this claim from Tea. I'm not aware of any laws which require platforms to retain raw identification documents, especially not for "cyberbullying prevention". Some laws require retention of user metadata like IP addresses, but retaining ID verification documents is plain reckless.

RISCOSbits releases new ECOS systems for Windows, Retro and Fileserving www.iconbar.com/articles/RIS... RISCOSbits have announced some new systems in their EOCS range (we have previously looked at the Linux version)

At the ROUGOL meeting on Monday, 21st July, we will be joined by Andrew Rawnsley to talk about R-Comp's new 5tuff rougol.jellybaby.net/meetings/ind...

Rougol July 2025 meeting on monday - R-Comp talks New 5tuff www.iconbar.com/articles/Rou... The July 2025 Rougol meeting is on Monday 18th July. It will feature R-Comp's Andrew Rawnsley talking about new 5stuff (and I expect some older stuff as well).

ZX Spectrum Next Issue 3 campaign started few weeks ago and already passed £ 1M, this is the 3rd campaign which passes it. Great to hear that! Side note: someone should definitelly remind #RISC_OS users and ROOL that RISC OS ain't a ZX Spectrum... www.kickstarter.com/projects/spe...

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:👇

Getting a bit tired of that whole "Emulation/FPGA/Reproduction is not real retro" gatekeeping to be honest. Let peeps have fun the way they want to have fun. It doesn’t matter what YOU think about it. I like repairing old hardware, don’t care as much about new retro stuff but many do & that’s ok. ☮️

Hear all about R-Comp's new systems at this month's ROUGOL meeting on Monday 21st July rougol.jellybaby.net/meetings/ind...
