The braking system on my car failed yesterday (I've got lots of amber glow).

At this point, I'm going to need to accept the repair bill, whatever it is.

I think my mind has been made up on if I'm going to keep this Prius long term but maybe I'll get lucky ...

(Brakes were at about 80%, and I've got cavitation in the system when I push the peddle so it might just need a flush and bleed, although it imples water got into the system from somewhere)

I think the main switch on my network gave up the ghost ...

Or at least is acting strange. I can access the Internet if I'm plugged into it directly, but other ports aren't working.

Its on a surge protector, but I suspect one of the power outages have done a normal. I'll see if I can rewire my wireless subnet somewhere else.

So I took a deep look at the OpenBSD/vax pmap code and DEC's system manual, and discovered that VAX's system manual says you must update the page table entries atomically by changing the PTE pointer register

Guess what OpenBSD (and NetBSD) don't do?

(it should be noted that I haven't confirmed this as the root cause. The original code would have had instruction and TLB caches cleared after running. I'm on an emulator which I suspect has no caching at all. However, the pmap code overall is ... interesting ..

TIL I learned that giraffes would count as kosher (herbivore that chews cud with hooves).

That's probably been relevant at least once in human history.

I had an extended power outage which knocked the stream offline. Here's how things stand right now

5.4: Compiled successfully, but ran into illegal system call with /bin/sh during make release

5.5: Compiled successfully, and is now several hours into make release. The scripts seem slightly broken, but its still going with handholding

5.6: Compiled successfully, but PANICKED with rmpage during make release.

5.7: Died during the original stream

5.8 building 5.8 on real hardware: Still going, in libressl. Will probably take 1-2 weeks to finish the base system.

This implies it might be a regression in 5.5 to 5.6, or a latent issue that was aggrevated in 5.6. Finding a good reproduction test case is going to suck though.

Well things continue to look up, I also now have a reproduction case that's 20 minutes vs 2-20 hours to reproduce.

I'm legitimately debating if I could possibly use SLIP over telnet to virtual serial to bypass Ethernet related pain

Man, so much wild shit breaks when you have a network driver MOSTLY correct.

OpenBSD 5.6 died after 60 or so hours in the make release step of the process ...

From my livestream chat, I've learned that OS-tans not only exist for even niche operating systems, they come with full backstories worthy of any anime protagonist ...

The compile still continues ... https://youtube.com/live/YCJuBvkfqpo

So I need to figure out what, if any the last version of OpenBSD that could actually self-host was.

The system is only unstable under load, so I think the easiest approach is to just run multiple instances of SIMH and see how far we get.

I hate whomever created it with the passion of a native New Yorker currently living in New Jersey experiencing the novelty of having an actual living space at only less than slightly less than astronomical costs.

After 64 hours, the OpenBSD base system has successfully compiled. I need to build the GENERIC and RAMDISK kernels, and then make a release.

Coming up on two days of OpenBSD building on VAX. https://youtube.com/live/zJUkVWBozTo?feature=share

This is way faster than real hardware.

After 14 hours, OpenBSD is still compiling in SIMH and I learned I need to click repeat in my music library: https://youtube.com/live/zJUkVWBozTo?feature=share - for those who want to watch paint dry
