I yesterday set chatgpt to a coding task. It utterly failed. Its error handling was extensive, but wrong. It didn't know file formats. It couldn't write the code when i told it the…

PWB Unix was the earliest sources I could find. FreeBSD lists history items for releases going back to the earliest unix release because BSD Unix is derived from AT&T Research Unix…

You forgot the following steps: Profile to see what's the slowest thing Make a native version of that. In FreeBSD package builder setup, we also have /bin/sh and a few other heavil…

I know the qemu-bsd-user fork has some hacks for the bsd-user stuff that looks at the binary to be exec'd and does different things based on the target since there's some optimizat…

FreeBSD has used this same trick for half a dozen years or so to build arm, mips and riscv binaries using fast Intel servers. The FreeBSD build system can build itself to produce b…

Shar's workaround is for leading white space. This is change is for not assuming traling newlines.

It absolutely shared history with Larry Wall's patch.... It took the 2.0 sources and started improving them. I ran across a blurb about this somewhere. Also, the code structure is …

The question too is whether UNIX is copyrighted due to the pre-berne convention distribution of the system w/o copyright notices... And there's also a question of latches as well s…

True. I'd been looking at an older version of gnu patch when I thought it hadn't been patched to fix this... It looks like it had a while ago...

Binary format changes are never fun to go through forwards... This blog entry explains how the 2.11BSD restoration project did it backwards as a step towards creating the boot tape…

Git's role would be to record the system incrementally as each patch is applied. I've already worked all the way back to the unpatched system. I assume that if I got it right, then…

No. 2.11BSDpl195 is the earliest one available. It's what was on the old PUPS disk... PUPS became TUHS ( http://www.tuhs.org ) and this is the oldest one there and none of the old …

It's my COVID-19 insomnia project...

It's hard to reverse apply 'rm /usr/src/bin/ld.c' in the instructions to patch 160, for example. You have to reconstruct ld.c from 2.10.1BSD, and then add missing changes to get it…

The whole reason I did this project was to get back to patch level 0 so I could create a github repo of all the 2.11BSD patches....

This will be reverted.

The last actual BASIC I wrote was in 1985.

Nobody! There were no copyright notices, and this is a work made before the US adopted the BERN convention. Prior copyright law required copyright notices. We learned from the ATT …

SIMH now has a reason to upgrade to support Graphics2: Looks like the spacewar source uses it!

It's not QR code, per se, but something quite similar...
