This looks interesting. Thanks for sharing.

I had the same inclination back in the 90s when I upgraded my Cyrix 486 SLC2 50MHz without a heat sink (which seems like a no-no in retrospect) to Cyrix MediaGX 133MHz. The stocker fan was immediately noticeable. I thought I had done something wrong.

There’s several other (well) known examples of the use of mujs.

There’s Artifex’s interpreter from muPDF. It’s also the basis of several JS related projects: https://mujs.com/

There’s also a lesser known interpreter: https://github.com/ccxvii/mujs

And IIRC, there was a CommonJS library of the same name.

Maybe you’re misremembering or referring to Doom (2016). The original Doom was developed for DOS and id had to build a lot of its own network stack. BSD style socket based networking wasn’t a given in DOS.

Still, zclaw is an impressive achievement.

   I don't feel like RedHat had to do anything to sell support contracts in this case, because that was already their business. All they had to do was say they'll include container support as part of their contracts.

Correct. Maybe starting with RHEL7, Red Hat took the stance that “containers are Linux”. Supporting Docker in RHEL7 was built-in as soon as we added it to ‘rhel-7-server-extras-rpms’ repo. The containers were supported as “customer workloads” while we docker daemon and cli were supported as part of the OS.

   What they did do, AIUI based on feedback in the oss docker repos, is those contracts stipulated that you must run RHEL in the container and the host, and use systemd in the container in order to be "in support". So that's kind of a self-feeding thing.

Not quite right. RHEL containers (and now UBI containers) are only supported when they run on RHEL OS hosts or RHEL CoreOS hosts as part of an OpenShift cluster. systemd did not work (well?) in containers for a while and has not been ever a requirement. There’s several reasons for this RHEL containers on RHEL/RHCOS requirement. For one, RHEL/UBI containers inherit their subscription information from their host. This is much like how RHEL VMs can inherit their subscription if you have virtualization host-based subscriptions. If containers weren’t tied to their host, then by convention, each container would need to subscribe to Red Hat on instantiation and would consume a Red Hat subscription instance.

I think STL was the intent.

Yes. 486 with 26MB for MicroCore (cli) or 46MB for TinyCore (gui).

VGA color palette was 18-bits/256K, but input into the palette was 8-bit per channel. (63,63,63) is visibly different from (255,255,255).

Not true. You can enable “Mount Mode of Operation: TCE/Install” where packages will be mounted off disk. See:

I don't know about CSI cameras. My use case for TCL doesn't require a CSI camera. But it looks like others have made a CSI camera work:

https://forum.tinycorelinux.net/index.php/topic,26713.0.html

I recommend asking on that forum. Folks are helpful.

There’s an installation option to run apps off disk. It’s called “The Mount Mode of Operation: TCE/Install”.

With some modifications, yes. Boot2docker and boot2podman were based on tinycorelinux.

With CorePlus, you have the the choice of some 10 GUI environments. I prefer openbox or jwm.

I love Tiny Core Linux for use cases where I need fast boot times or have few resources. Testing old PCs, Pi Zero and Pi Zero 2W are great use cases.

Only if they never call DOS or the BIOS or execute a Real Mode Software Interrupt. When they do, they ask the DPMI server (which could be an OS like Windows 9x or CWSDPIM) to make the call on their behalf. In doing so, the DPMI server will temporarily enter into a VM86 Virtual Machine to do execute the Real Mode code being requested.

VM does not mean Virtual Memory in this context. VM does mean Virtual Machine. When an OS/DPMI Server/Supervisor/Monitor provides an OS or program a virtual interface to HW interrupts, IO ports, SW interrupts, we say that OS or program is being executed in a Virtual Machine.

For things like Windows 3.x, 9x, OS/2, CWSDPMI, DOS/4G (DPMI & VCPI), Paging & Virtual Memory was an optional feature. In fact, CWSDPMI/djgpp programs had flags (using `CWSDPR0` or `CWSDPMI -s-` or programmatic calls) to disable Paging & Virtual Memory. Also, djgpp’s first DPMI server (a DOS extender called `go32`) didn’t support Virtual Memory either but could sub-execute Real Mode DOS programs in VM86 mode.

There were loadlin and grub4dos back in the day. A more recent development is doslinux (https://github.com/lpsantil/doslinux) but it is far less complete. But more hackable if you just want to see something work.

I went smallwall after m0n0wall was shutdown. I recall the smallwall & smoothwall maintainers briefly considered joining forces.
