#as400 — Public Fediverse posts

My first successful PCB project. This connects a PS/2 keyboard and mouse to the Netfinity PC card set on the #as400 Model 150 and probably others. I'll be uploading Gerbers later this evening.

The other fun project of the weekend was another kind of beast:

I wanted to be able to listen system output from specific RPG programs running on our AS400

The idea was the following:

could I generate a graph from dependencies used when X or Y RPG routine run?

I wanted to be able to map physical programs from libraries and other dependencies.

so I went the Java path since its the main language we use to interface with AS400 routines.

Then I used Neo4J to graph the output of the Java ibmi listening server.

I’m probably going to write a long form about this since it was really interesting to vibe code.

At some point I had to query the RPG routine themselves to be able to find key dependencies my main RPG routines were using.

so I basically created an API endpoint that I can query with specific program names to then find their dependencies and again graph the results to Neo4J

I still have to fine-tune the codebase before I publish this publicly but I’m pretty happy about the results

Je viens d'apprendre par la RTS que le #SECO avait un #AS400 et qu'ils ont changé et depuis plus rien ne marche, Les chômeurs ne sont plus payés. Dans les caisses il y a maladies et démissions. Il faut faire quelque chose. Un rollback

I wonder if it will play nice with the others ... #as400 #systemi

10/x

You’ll (perhaps) be glad to know that after hitting some mysterious key-combo on the keyboard at work, when this heretofore undiscovered & unimagined window popped up on my computer screen, I did not hit “Cmd6.”

Be thankful? Maybe?

Who knows, you might have woken up this morning in a very different world. And I may have suddenly found myself sitting in a barnyard with a cow licking my cheek.

I really enjoyed this booth at #VCFMW19. Sadly didn't get the name or fedi handle of the folks presenting it, but I had no idea about the IBM AS/400 machines.

@emi_cpl they actually run on AS400s 😉 #ibm #as400

so...

today I learned how to use deactivated accounts to reactivate and change passwords on those same deactivated accounts on the #as400 leading to a silly chain of "use one account with restrictions to change password or reactivate an account with no such restrictions", and do it again and again and again until ultimately resetting qsecofr and the system tools account BECAUSE apparently with delicacy, one can assume privileges of another account by invoking that account

what a rush

I once worked on a software project for #trump #casinos. We built a wicked functional demo for their #rfp.

Trump bought 3 casinos, each one was run on its own #AS400 mainframe in the basement of each site.

My team created a web app that pretended to be an AS400 terminal. We mapped out all the locations on each screen where text would appear or be entered, and using "screen scraping", we'd automate the remote system, pushing & pulling data between the web app and the 50 year old mainframe.

This allowed a booking agent to pull up the app, and check availability etc at not just one, but all three properties at once.

It was brilliant software. I had never even seen a line of #cSharp before that project, but I left with a profound respect for it.

Trump being Trump, he lost or sold one or two of those properties before we could sell them our solution, and the whole thing went nowhere.

#softwareStories

i have been doing absolutely NOTHING ELSE except for #as400 work for the last three days and it has been exhilarating.

do i start training to become an as400 admin/dba/programmer/analyst?

1 for yes
4 for no

f21 for all

🔬📺 New project in the lab: the IBM AS/400 system (pictured on the cart in the background) and its OS/400, localized into Slovenian. IBM provided terminal keyboards with special characters (anyone for F24?), and terminal support is also in place.
