Folks, if you or you kids can get ANY vaccines or boosters that they will need, get them NOW. I think they will first target HPV, so definitely make sure your kids get that. They can give the first dose at 9. And you are eligible until you are 45. Also, if you are Gen X and might only have had one dose of measles vaccine (was the standard for a while) or if you might have missed the MMR at any point, GO GET ONE TODAY. You CAN ask your doctor to titer you, which is fine, but if you don't have time or medical insurance, you can also just go get the vaccine.

@jfmezei One of the reasons VAX is comparatively slow involves the condition codes, including the carry bit.

~Every VAX instruction is a test instruction, if you want it to be.

But if you break that part of the VAX design to make the architecture go faster, you might as well also break, err, alter some other VAX architectural design constraints. After some other work including Prism, that architectural replacement was Alpha.

As assemblers go, VAX is quite nice.

But assembler as a choice for app development started to fade around the era of the 3GL vs Assembler debates; the early to mid 1980s.

Section 8.4 has details of the VAX condition codes:

A number of years ago, I did some fun vector art minimal wallpapers featuring retro hardware. I haven't posted them in a while, so please enjoy this TI SR-51, a PDP8-e, a trio of IBM 2401 drives, and a VAX11/780.

Please feel free to use and share these freely (though please also provide attribution if you do!)

I posted yesterday about how NetBSD/m68k compile itself from scratch on real m68k hardware. m68k is a clean architecture with good gcc support and even llvm support, so it shouldn't come as a surprise that this works, even if it does take two months on a decently fast m68040.

But what about #VAX?

There is a DEC NIC (the DEBNA and DEBNK) with both an on-board VAX chip, and an 80186 chip.

Expensive chip choices aside, this NIC could continue to run with the VAX host entirely shut down, if the VAXBI host bus was not specifically reset.

Which meant you could successfully ping a downed host, as the VAX and 80186 and firmware running out on the NIC could conspire to process that traffic autonomously.

Fun times.

Homeopathic science: The fewer scientists that holds an opinion, the more correct that opinion is.

All scientists says global warming is real and human made? You can not trust in science!

One scientist says the ice isn't melting? Science is great!

All scientists says vaccines we have given to millions of people over decades are safe and efficient? Science is all just a huge lie!

One scientist says the vaccine is terrible? Listen to the scientist!!

@DL1JPH exactly that

It's the reason banks still roll their systems on them and why I know the story if a #COBOL developer who literally fixed their mothers' code that was older than they are...

  • Same reason why #hp still has to maintain #OpenVMS & #VAX systems, as #DoD (on behalf of the #FAA) demanded them to uphold the open-ended, single-side - only cancellable contract that #DEC signed and that they inherited throigh #Compaq's acquisition of DEC, as the #ATC Systems of the U.S. runs off those machines...
