Hey fellow #RetroComputing #RetroTech weirdos (affectionate),

Over a decade ago, Blackberry was just giving their tablet, the Playbook, away to anyone who offered to try developing apps for it. They didn't last long enough to ask for it back. So natch, I got one and played with it a bit.

Now, it's still fully functional and collecting dust. None of the upstream infra or app store exists anymore, but I was hoping to still screw around with it. It's #QNX, an RTOS, which is neat. Right?

Anyway, does anyone else mess around with this kind of thing? The apps needed to be signed to work, even in dev mode.

Security Patches

InfoSec

Regardless of which Operating System you run, it is important to keep up with the critical updates to keep your machines as safe as possible

• Realize that by the time a critical bug has been reported, verified, patched and delivered to your distribution of choice, a significant amount of time has passed...
• From the first day the bug has been discovered [zero day] to the day you patch your computing machine, you've had a vunurable open machine in that one respect.
• Keep the amount of time between the availability, of patches & the update of your machines, especially your VMs (Qemu et al) & physical servers as short as possible
• Make sure to always use manual updates on your server VM's!
• I shall not explain why, start reading on Wikipedia and furthe, the explanation is too long for this short post

Notes:

• every OS can have vunurabilities
• Security in obscurity does not work!
• you are not secure because you run obsolete AmigaOS QNX or cool and niche *BSD as an OS
• buffer overflows hide everywhere
• I reguraly find them!

Wow... Blackberry really hit a vein with the #qnx developer desktop. Trying to read the docs and mostly getting 429 "Too Many Requests".

I have QNX 8.0 on my rpi4 and it's definitely cool and fun. I'm really interested in the desktop now too.

interesting: #qnx have adopted apk as their system package manager: https://www.qnx.com/developers/docs/qnxeverywhere/com.qnx.doc.qdd/topic/using_apk.html

and they use #abuild now too: https://github.com/qnx-ports/qsc-apk/tree/main

and they even comply with the GPL license, but their patch is not mergable in the current state: https://github.com/qnx-ports/aports/blob/803/core/apk-tools/0001-qnx-compat.patch

QNX — второе дыхание в ретрогейминге Super Nintendo

Здравствуйте, уважаемые читатели! Сегодня мы еще раз вспомним об интереснейшей операционной системе QNX . На сей раз мы используем QNX в качестве игрового стенда для запуска игр от SNES посредством эмуляции. И DOOM , конечно же, будет — DOOM . А вы знали, что он портирован на SNES ? С музыкой, все дела… Приглашаю всех, кому интересна экзотическая операционная система в нецелевом использовании для ретрогейминга, для ознакомления под кат. Папуль, можно поиграть? (c)
