## ChatGPT Will Never Write For Exploring Binary

I got an unsolicited email from a company offering to write AI (ChatGPT) generated articles for my site. This is the snippet they sent of their sample article:

Mastering Decimal, Binary, & Two’s Complement Conversion

In the digital world, understanding numerical notations like decimal, binary, and two’s complement can provide a substantial advantage and presents opportunities for improved problem-solving. The journey starts with the basic foundation of decimal …

I did not click through the tracking link to get the rest of the article but it looks like the generic fluff ChatGPT wrote when I asked it about Exploring Binary. It’s worse than fluff actually; I don’t see how knowing numerical notations helps with problem solving.

If you’ve read anything on this site you’d know immediately that I didn’t write that. Will AI ever be able to write an article indistinguishable from one of my own? I don’t think so.

## College Notebook: When I Was Taught Floating-Point

In my article “Floating-Point Questions Are Endless on stackoverflow.com” I showed examples of the many questions asked that demonstrate lack of knowledge of the most basic property of floating-point — that not all decimal values are representable in binary. In response to a reader’s comment on my article I wrote:

It would be interesting to know how it’s taught today (it’s been a very long time since I was taught it). I can’t imagine though that the person teaching it wouldn’t say — within a sentence or two of saying “floating-point” — that it “can’t represent all decimal numbers accurately”.

That prompted me to look through my box of thirty plus year old college (undergraduate) notebooks. I found notebooks for four classes in which I was taught floating-point. The notes from three of those classes confirm what I thought — that we were warned early of the decimal/binary mismatch. But in the first class of the four — the beginner’s class — it’s less clear what we were told. I’ll show you images of the relevant excerpts from my notes. (I notice I had some elements of cursive in my handwriting back then.)

## Exploring Binary On My Apple II

I’m reading Steve Wozniak’s 2006 book “iWoz” and this line got me wondering about my own Apple II:

“In every speech I give, I talk to people who are still running Apple IIs, and they say those machines are still running after this many years.”

So I got it out of the attic and powered it up. The dozen or so dead keys notwithstanding, it still works — after 30 years!

## My Goals for Exploring Binary in 2009

Well, it’s been one year! I’m very happy about how things are going, even if I didn’t meet any of my goals! (See below for how I did in 2009.)

This post was motivated by the article “What Are Your Internet Goals for 2009?”, by Daniel Scocco.

Since I am new to blogging (I just started this blog a month ago), my internet goals for 2009 are my goals for Exploring Binary specifically. I’d like to get this blog off the ground before I try anything else!

I’ve been maintaining a long list of things I want to accomplish with this blog, but I whittled it down to the most important goals — all challenging but realistically attainable:
