#mainframe

I’ve been digging harder and harder into AI, mostly regarding historical information and synthesizing ancient history and language.

What it has come to remind me of was 46 years ago in 1980 at Cal Poly when I was submitting card decks to the big computer behind the wall.

Nachher dann im #Mainframe in #Oldenburg zum #Silvester feiern? 🎆
Die haben dort schon Angst bekommen, das alle meine Follower kommen könnten, deswegen mache ich nur ein bisschen Werbung dafür. 😁

Es wird eine bunte Runde und so mag ich das. Es ist schon geöffnet. Einfach bei der grün leuchtenden Klingel klingeln, man muss dann etwas warten, bis jemand die Treppen runter kommt und auf macht.

Ich brauche noch ein bisschen, muss ja die Nacht durchhalten und noch einen Salat zubereiten. 🥗

A screenshot of a VM/CMS EXEC script. A Christmas tree made of asterisks is visible along with the text “a very happy Christmas and my best wishes for the new year.”

Comments read “browsing this file is no fun at all just type CHRISTMAS from cms” and “let this exec run and enjoy yourself!”

THE IMMORTALS & THE SHADOW REALM Teaser
-
Mainframe, the place that made ReBoot, Beast Wars, and many other things has a new franchise it is developing. the Canadian animation house is making a new action adventure series.

No word on a home for this. This is prob to find a home. But pretty impressive.

@karl

web apps were always about tearing the data away from us

from our stand alone computers, disconnected and un-watched

charging us for time and space on centralized services is always what computing has been about

always

rent

making us rent out ability to access software

renting access to centralized resources

forcing us along the path of progress

deprecating old stand alone formats

deprecating independent self hosted services

#mainframe -> #cloud

With some help from the SZE community, I can now log my service uptime and latency in #Db2 using #Golang !

I've got a service called CompInvZ which links into my Db2Z host to find services, then it periodically tries to connect and records the result back to DB2

A friend of mine took it a step further and is using #ISPF to interact with Db2 via #REXX

That means #CICS is next on the list, thanks #Walmart !

Weirdest #mainframe thought I've had in ages:
has anyone made a USB punched card reader? It should work with Hercules easily enough, and them I could use my old backups of Assemler XF macro source code again :-)

And does this count as #Nerdware?

@raspel @Shi
Ja, da kann ich mich nur anschließen. Das war wirklich schön euch mal 'in echt' kennen zu lernen. Viele interessante und nette Gespräche und auch der Einblick in diesen beeindruckenden Makerspace war wirklich spannend!

Vielen Dank an @Shi für die tolle Organisation!

#mainframe #PL1 Doing some more Iron Spring PL/I under Linux, and it's really jolly good. I haven't disagreed with any of the choices they made to make it useful on this OS :-)

I'm not quick yet (keep referring to docs for "is it index(needle, haystack) or index(haystack, needle)" but already I'm writing fewer bugs than I ever did with C :-)
#IronSpring

Hint if trying: compile with something like:-

plic '-C -N -dELF -cn(\!) -lvosmnxg hello.pli'

ld -g --oformat=elf32-i386 -melf_i386 -z muldefs -Bstatic -M -e main -t -o hello ./hello.o -lprf

Also to the "look how few vulnerabilities we have" comment made today at one of the #mainframe #security talks:

I'm sure they did a lot of good things. Not saying it's just due to this or anything, I'm not that deep in mainframe. But I also wanna say something with "security by obscurity". Which we all know... is no security at all.

OMW home. Bit later than most attendance's of #nluug25nj. But that's because the #PvIB had a meeting on #mainframe security afterwards in the same place that I impulsively joined.

It got me free dinner, some talks to listen to, then had some nice talks with people I'll less often run into. You never know when the knowledge comes to use. I heard you technically can write your own OS if I quote "you're crazy enough" and manage to get the hardware. The later seems the bigger issue 😏
