Hello, world

Just never have, ever.

Not even a Hello World sample.

Yeah.

And I was fascinated when the Microsoft DOS 1986 code was put out open source on Tim Patterson's GitHub.

But, you know, a few hundred, try avoid.

And just the sheer fact that it can do so much means that a Hello World simple terminal app written with Oakcliffe is actually quite a lot of code spread over a number of files.

Because it's not a tool designed to do a small thing.

It's a tool designed to do a big thing.

Without the indent, it would break my head.

Yeah.

And so that means that a hello world is actually four lines.

const cli equals new command dot name hello world dot description print the universal newbie message dot action async fat arrow function console dot log hello world.

And with Rock, I made the choice that you can only use Qt.

And how Hello World would look like syntax with Qt? To give your audience an example.

Yeah.

It's curly brace, your variable, and you close your curly brace.

But in working with Computers by Design, they had a program called Visual Basic 4.

And I was like, ooh, what's this? And then it was basically, you know, your first program anybody does learning programming is Hello World.

And it's basically, I make a button and he said, click me on the button and it pops up with the label, says Hello World.

And I was like, this is amazing.

I can sell this.

And in response, this is a tour of the co-evolution of Unix and C.

From this perspective, featuring Hello World through the ages.

This work is entirely my own, no AI, and the code samples are my construction sources for all inferences are cited.

ASCII 1963.

Trigraphs and diagraphs.

Curly braces were prominent part of C syntax used for blocks.

For example, int main, int arg char print hello world.

I suggest going to the show notes and actually seeing some of this because I won't be speaking out much of these code snippets.

You go figure it out, right? So we want you to get started with the model and then build from there.

Speaking of getting started, right, when you install Docker, like there's the Hello World version of Docker, right, where you just see it's working and things are good, right? Well, you've already mentioned that you can go to stackautomation.cisco.com and sign up for an account.

What would be, for our listeners, sort of the Hello World equivalent of Stack Automation, where somebody could just go and not do this end-to-end workflow, but literally get Hello World on the screen, or whatever the similar, the equivalency would be for Stack Automation?

Yeah.

Well, this is a tool, right, from its DNA or from its... from the ground up, we tried to do it as frictionless as possible, right? All the mechanics around it.

We have self-contained the mechanism so you can consume that resource within Stack Automation.

Just click on it and we're going to open that resource for you.

That's the version of the hello world.

Okay

... canonical Swift with Xcode, you know, the entire Apple ecosystem, best model, and I wanted to have Hello World, whatever, and it already stopped during the build phase.

So it-

Mm-hmm.

It's like jumping straight into a flight simulator.

You type that legendary first command that every programmer learns, right? Console.log, hello world, and you hit run.

Yes.

And there's this immediate raw power in that execution loop.

We could chat back and forth normally.

Like if we're just talking, we don't, but once we have a bunch of changes, so if you can think of a change, uh, Yep, you got your hello world.

Let me think of a

world.

let's try that.

Yeah, let's see what it does.

So I'm going to click on your Hello World.

I'm not going to send that in, even though it wouldn't do anything to the agent.

And coding challenges was one of these things that I have always learned a new programming language by building little applications.

So I'd grab a book, learn just enough to be able to do "Hello, World," and then I'd start wanting to build something more real.

I don't wanna just write another factorial function.

I don't want to write another class that represents a chair in another language.

Ah, yeah.

Hash include angle bracket, this standard io.h thing." And I went, "What, what the hell does that do?" And I've read the whole book and-- But it, it didn't really sink in from just reading this book cover to cover.

It's when I then sat down and typed in the "Hello, World" and typed in the code and then went, "All right, cool.

That says, 'Hello, World.' How do I get it to say, 'Hello, World, John'? I've gotta read something from the keyboard.
