Trying to learn the REXX scripting/programming language. It surely requires some modifications in my brain after all those years with C-style languages. Or maybe brain damage…

Bought original box version of OS/2 Warp 4 yesterday. That would probably be the first original operating system for PC compatibles I ever bought.

A new post on my PowerPC blog after some time: Windows NT on Bull Estrella

Spent holiday learning and trying OS/2 - all the way from OS/2 1.3 to ArcaOS - reading books, trying in VirtualBox as well as on the bare metal. Great OS for its time and wonderful that it still has some development.

So I am now FidoNet point at 2:423/81.41 - anyone else? :)

Building QEMU from git sources… directly on my phone. So far so good: make is on step 3688/9125 after 2h33m from starting.

I’ve got Ryzen 5 3500X very cheaply (like $20 for both CPU and board), because it - I quote “doesn’t run Windows, just Linux”. It’s a six-core/six-thread CPU originally targeted to asian lower-end OEM market, having SMT turned off permanently and it’s the only Ryzen 5 3xxx missing in Windows 11 supported AMD processors. Indeed, both Windows 10 and Windows 11 installers ended in B.S.O.D. around 20% from the start. But when installed elsewhere, Windows 10 worked without any error, so I started tinkering in EFI setup… Long story short: There is an option in EFI called “SMT”. It has two possible states: Disabled and Auto. When set to Auto, Windows fail to install, when set to Disabled, both Windows 10 and 11 work. It seems that both systems simply presume the CPU has SMT and fail when trying to use it. When SMT is disabled in EFI, this does’t happen and even Windows 11 recognize the CPU as supported and install from the original ISO without any modifications. Mystery solved.

I felt this weird last time when I tried to seriously use Plan 9. I don’t even know even how to reply to someone as it doesn’t seem like the original twtxt Python client supports the topic in brackets. But I managed Gopher, Z80 assembly, and paddleboarding, I will manage twtxt as well.

This twtxt thing is very new to me. Strange clients, I don’t know who to follow, I even do not understand the timeline. Nice.
