29-year veteran here. Began programming professionally in 1990, writing BASIC applications for an 8-bit Apple II+ computer. Learned Pascal, C, Clipper, COBOL. Ironic side-story: back then, my university colleagues and I used to make fun of old COBOL programmers. Fortunately, I never had to actually work with the language, but the knowledge allowed me to qualify for a decent job position, back in '92.

For a while, I worked with an IBM mainframe, using REXX and EXEC2 scripting languages for the VM/SP operating system. Then I began programming for the web, wrote my first dynamic web applications with cgi-bin shell and Perl scripts. Used the little-known IBM Net.Data scripting language. I finally learned PHP and settled with it for many, many years.

I always wanted to be a programmer. As a kid I dreamed of being like Kevin Flynn, of TRON - create world famous videogames and live upstairs my own arcade place! Later on, at some point, I was disappointed, I questioned my skills, I thought I should do more, I let other people's expectations make feel bad. Then I finally realized I actually enjoy a quieter, simpler life. And I made peace with it.

I'm now like the old programmers I used to mock 30 years ago. There's so much shit inside my brain. And everything seems so damn complex these days. Frameworks, package managers, transpilers, layers and more layers of code. I try to keep up. And the more I learn, the more it seems I don't know.

Sometimes I feel tired. Yet, I still enjoy creating things and solving problems with programming. I still have fun learning. And after all these years, I learned to be proud of my work, even if it didn't turn out to be as glamorous as in the movies.

It was 1957 and this was a 1 byte ram memory module for an IBM Mainframe.

So for those of you keeping track, I've become a bit of a data munger of late, something that is both interesting and somewhat frustrating.

I work with a variety of enterprise data sources. Those of you who have done enterprise work will know what I mean. Forget lovely Web APIs with proper authentication and JSON fed by well-known open source libraries. No, I've got the output from an AS/400 to deal with (For the youngsters amongst you, AS/400 is a 1980s IBM mainframe-ish operating system that oriiganlly ran on 48-bit computers). I've got EDIFACT to deal with (for the youngsters amongst you: EDIFACT is the 1980s precursor to XML. It's all cryptic codes, + delimited fields and ' delimited lines) and I've got legacy databases to massage into newer formats, all for what is laughably called my "data warehouse".

But of course, the one system that actually gives me serious problems is the most modern one. It's web-based, on internal servers. It's got all the late-naughties buzzowrds in web development, such as AJAX and JQuery. And it now has a "Web Service" interface at the request of the bosses, that I have to use.

The programmers of this system have based it on that very well-known database: Intersystems Caché. This is an Object Database, and doesn't have an SQL driver by default, so I'm basically required to use this "Web Service".

Let's put aside the poor security. I basically pass a hard-coded human readable string as password in a password field in the GET parameters. This is a step up from no security, to be fair, though not much.

It's the fact that the thing lies. All the files it spits out start with that fateful string: '<?xml version="1.0" encoding="ISO-8859-1"?>' and it lies.

It's all UTF-8, which has made some of my parsers choke, when they're expecting latin-1.

But no, the real lie is the fact that IT IS NOT WELL-FORMED XML. Let alone Valid.

THERE IS NO ROOT ELEMENT!

So now, I have to waste my time writing a proxy for this "web service" that rewrites the XML encoding string on these files, and adds a root element, just so I can spit it at an XML parser. This means added infrastructure for my data munging, and more potential bugs introduced or points of failure.

Let's just say that the developers of this system don't really cope with people wanting to integrate with them. It's amazing that they manage to integrate with third parties at all...

I am attending a lecture about IBM mainframe computing and I have no idea about what the lecturer is talking about

Company paying tons for retired old mainframe devs to come teach basic z/OS and to give a hands-on. Third try and they still sent a guy showing off their windows based mainframe replacements without terminal connections.

I set an pirated z/OS up and now I have to deal with 10 coworkers who apparently can't unpack a 7zip, follow basic instructions or failed to open the .torrent with files i distributed 14 days ago. Losing the will to live (in legacy tech)

Seriously, what's the difference between a supercomputer and a mainframe computer?

!Rant

I am just curious about why the CoBol compiler in IBM mainframe is IGYWCLG.

#notrantrelated

I find it hard to think what to code and what to make. Currently I'm joining a contest and I need to come up with something that would be beneficial to mainframers. I've joined IBM master the mainframe 2020.

Can you suggest me on what would be cool to make? They want something awesome. And I'm sorry for asking you guys to help me.

Any ideas will be appreciated. Thank you :)
