@tg9541 It's a Haswell CPU. It replaced a gen4 i5 of some sort - maybe a 4570T? It's been surprisingly reliable in the old machine.

I started maintaining MAME on Haiku because I wanted to run Psion emulation on it. So there's actually a good reason for the sidequest! 😁

On June 29, 1994, I announced what turned into the FreeDOS Project.

That's 31 years ago today! And I thought what better way to celebrate the anniversary than by showing how to install FreeDOS.

We released FreeDOS 1.4 in April, so it's been out for a while. If you haven't installed 1.4 yet, here's what it looks like:

Revisiting my trip across Canada got me pining for my old Psion 5mx. Remember PDAs, back in the days before smartphones? Well, as a writer, this one stood above the rest. But can I find a modern equivalent?

I didn’t plan to write about Wayland yet. But Xorg is dying — not eventually, but now. GNOME’s dropping X11 support. RHEL already removed it. Ubuntu and Fedora are next. And if you rely on accessibility, you don’t get to wait this one out.
So here’s Post 4 of I Want to Love Linux. It Doesn’t Love Me Back.
I’m using Wayland now. Primarily. Not because I love it. Because the fallback is disappearing, and I want to be there helping fix what comes next. GNOME with Orca actually works. KDE and COSMIC are making progress. I’ve talked to the people involved. They care.
But a lot is broken.
MATE — the desktop most blind users preferred — isn’t on Wayland.
ocrdesktop doesn’t work. xdotool is gone.
wlroots compositors still don’t reliably support Orca’s keybindings, especially on laptops.
This isn’t GNOME’s fault. They’re the only reason accessibility on Wayland works at all.
But the old excuses are gone. “Just use Xorg” isn’t going to be an option much longer.
So yeah. I’m a Wayland shill now. Because I’m using it. Because I have to.
And I want to make sure we’re not excluded from what comes next.

#PicoGUS is now an ODE! I've just released firmware v3.0.0, which adds Panasonic CD-ROM drive emulation. Put some ISOs or BIN/CUE files on a USB stick, plug it into your PicoGUS, and you've got a virtual CD-ROM drive that works in DOS and Windows 9x and supports CD audio.

woke up about 2am thinking about the PDA I owned in the early 00s. Man, Jobs really did a number on the whole tech industry with the iphone, hey?

Turns out the author of Kinetic Worm Dimension, a fast paced "three dimensional" implementation of Snake, still had a backup of the original 1999 DOS version of the game. It was previously unpreserved on the Internet, so he decided to share it.
