My first professional dev job was COBOL and it's associated tech, a majority of the stuff we did was banking stuff and at the time it seemed like that's what a majority of the COBOL market took up but I could be wrong


Ah COBOL, oddly enough I started my first dev job in COBOL in the banking industry(I'm in my 30s and started my professional coding career in my 20s), I have mixed feelings about it...it's a weird language but it has it's place, I wouldn't advise anyone to jump into a COBOL career path unless you are doing it for a job and a job alone.


I would kill to get a personal mainframe though. Read a story some time ago about some guy who snagged one from a government auction. Sadly they never have anything cool when I look.


I remember that story. I don't think he ever got it working. There's a lot to getting a real mainframe running, starting with some onerous licensing terms for the software. And the cost to power one would be ugly.

There were some actual 'personal mainframes' made by IBM. The PC/370 was a PC or PC/AT with a set of ISA bus mainframe processor addin cards. The PC became the I/O processor. The PC/390 was a later version based on a PS/2 running OS/2. All long obsolete now.


He did, his talk about it is really interesting: https://www.youtube.com/watch?v=45X4VP8CGtk

> He and his old computer friends played around with some applications that were on the platform, and even made an FTP server that put some data on the internet.

Fun, thanks for that. I clearly stopped paying attention too early. Awesome they stuck to it.


You can get a free account on one, for example in Master the Mainframe.

Sure, it's not half as cool as having the machine like that guy, but you don't need to reinforce the floor in your house, so there's that.


Ebay sometimes has them

Otherwise if you live in the Midwest...uw oshkosh use to have one for free. The stipulation was that you had to remove it from the campus. And it weighed 3 tons


The Hercules emulator plus the MVS 3.8j version of the IBM mainframe operating system are both freely available.


Buy one. IBM still produces them.



This looks really awesome I've always been curious of mental models so I just ordered a copy from Amazon. Also Gabriel, kudos to your work and DDG, I'm right near DDG headquarters and it's nice to know things like DDG are being created in my area.


Thanks!


Why learn Rust over C++?


Well, my answer is this: Coming from the perspective on a Pythonista, C++ seems tedious and error-prone. Rust, on the other hand, is merely tedious -- which is progress of a sort, one has to admit.


Coincidentally, I personally started learning Rust as C++ was a lot more difficult to learn by myself. The Rust book[1] is a great resource as it makes learning pretty complex topics fairly easy to approach.

Personally the thing that really sold me over was the "Building a guessing game" section, as it showed how to use the build system to pull in external libraries. I found these aspects specifically difficult to learn when learning C++. Plus, after learning Rust, I was able to go back to C++ and better understand it. Still have no clue about build systems though.

I think quite a few companies(and maybe even a good majority of them) will end up overpromising and underdelivering when it comes to AI products.


That will likely include Google with their effort to use "AI" in data analysis and search.


So, no different to most products then? We mainly stick with the ones that work.


The PDF is in Comic Sans so I've also included another link to the paper that doesn't use Comic Sans https://www.brynmawr.edu/cs/resources/beauty-of-programming




I'm in PA as well and have always wanted to take my kids but maybe I'll wait until they are a little older, thanks for the tip.


Hi Adora, can two members of the same company each sign-up or should all members of the company go under one account? Thank you!


Only one member needs to sign up the company, and at the end of the sign up process, s/he is asked to provide their co-founders emails to invite.


Great, thank you for the help!
