TI - Graphing Calculators

If you went to school in the US during the 1990s, and in to the early 2000s, you probably owned, or at least used, a Texas Instruments 80s Series calculator.

The TI-81 was released in 1990 and immediately gained ground in schools across America. This z80 based hand-held computer was able to do anything a scientific calculator could do. It even included TI Basic, a Basic language which allowed users to write in programs to solve very complex problems. None of this was really new. Programmable calculators had been out for years. But the new trick up this calculator's sleeve, was the ability to draw graphics; specifically graphs.
This was obviously something that was typically reserved for more capable computers at the time.
For less than $150, you could own a hand held computer.
School districts across the country began purchasing class sets. TI made it easy by bundling sets with a teacher's edition of the calculator. The teacher's edition was specially modified so it could connect to an external lcd screen and be projected on the wall. (More on those another day.)

But the TI-81 had one fatal flaw. Something that really kept it from becoming the defacto standard.
Every single person had to manually enter in thier own programs. This meant that if you came up with something amazing, you couldn't share it. Worse, changing the batteries wiped the full memory.

This limitation didn't last long as Texas Imstruments released the TI-85 in 1992.
This new model used the same z80 processor, bit was somehow now many times faster.
This new calculator corrected many issues with the TI-81 including adding a backup/coin-cell battery (they added this to the TI-81 around the same time. But it wasn't there originally.) And the greatest improvement of all...
TI-Link
This new, little cable, meant that programs could be shared between students and teachers. The cable, which was simply a 3-wire cord with a 2.5mm jack on each end, changed the world for students.
Very soon after the release of the calculator, Texas Instruments released the TI-Graph Link cable, a serial cable allowing users to connect the TI-85 to a windows 3.11 or Mac OS computer, copy files and even write programs on the computer.

This new calculator came at a much higher price, preventing it from gaining mass adoption.

To be continued....

KDE Attacks Critics as "Sad People" Who Are "Straight Up Lying"

KDE is in damage control after recent moves to restrict the systems which can run KDE Plasma (via Wayland & SystemD). Saying criticism is "FUD" and "fake".

Humans are Now Censoring Other Humans to Protect Feelings of AI Bots

The term "clanker", a derogatory term for "Al Bot", is causing people to be banned across the Internet (Reddit, Discord, Social Media, etc.). Because it might offend Al... and, apparently, Al Bots are more important than humans.

The futility of Ad-Blockers

Ads are filling the entirety of the Web -- websites, podcasts, YouTube videos, etc. -- at an increasing rate. Prices for those ad placements are plummeting. Consumers are desperate to use ad-blockers to make the web palatable. Google (and others) are desperate to break and block ad-blockers. All of which results in... more ads and lower pay for creators.

It's a fascinatingly annoying cycle. And there's only one viable way out of it.

openSUSE says "No Lunduke allowed!"

Those in power with openSUSE make it clear they will not allow me anywhere near anything related to the openSUSE project. Ever. For any reason.

Well, that settles that, then! Guess I won't be contributing to openSUSE! 🤣

Don’t Listen to Lee, Listen to Chris Lattner

Who is Chris Lattner? The guy who developed LLVM (the compiler infrastructure), Clang (the C/C++/Obj-C compiler frontend), and the Swift programming language. Someone far more able than I to evaluate the achievement Anthropic made with their “mostly AI” coded Rust based C-compiler.

https://www.modular.com/blog/the-claude-c-compiler-what-it-reveals-about-the-future-of-software

You will hear themes I’ve been saying a long time. It is not “AI can code compilers by itself” but that there will be human+AI co-development.

"ThePrimeagen" gave his hot take - Anthropic lied - and pointed out all the ways the compiler sucked or wasn’t original or needed the existence of the gcc to crib from. And he’s right in terms of what he paid attention to.

What folks are missing is that Anthropic did not hire compiler development experts, team them up with the best agentic orchestration professionals in the world, and embarked on creating a breakthrough...

Google Antigravity Built Notepad in ONE SHOT

This is my second entry into Notepad replacement week. Written in C# with WinForms it really is a nice little Notepad replacement, unlike my Zig based terminal version.

I wanted to demonstrate using Antigravity in it’s Agent Mode. In the video I go through the work flow so you can see the process.

I first ask the agent to help select a tech stack that will best allow a Notepad clone that it could build autonomously. I went with it’s recommendation. I have zero knowledge or skill in C#, nor in building windows applications (well, I used to do Visual Basic 25 years or so ago).

We then go through my process that I call AgentFlow. I direct it to create a product-definition.md and design.md. You have to know what you are trying to accomplish and how you will achieve that goal. Then a sprintplan.md. Sprints are small subsets of functional code that can be tested. In a more ambitious project, you might not be able to get done in one session. A ...

4th Wall Almost Full, $89 Lifetime Deal Ends Very Soon

Woo-hoo! The 4th Lunduke Journal Lifetime Subscriber Wall of Shame Awesomeness is almost full!

  • That means that, within the next day or two, the massively discounted Lifetime Subscriptions will go back to their normal price. So if you wanted to snag the $89 / $99 Lifetime Sub (instead of paying $300), now’s your last chance.

  • If you are already a Lifetime Subscriber and want to be added to the 4th (or the start of the 5th) wall, email me (bryan at lunduke.com). There are only a couple of spots left on Wall 4.

  • The new Lifetime Wall designs are locked and loaded, and will make their grand debut at the end of all new shows starting either Friday or Monday.

I also wanted to take a moment to thank all of the non-Lifetime Subscribers. The Lifetime Subs may get a little extra attention at the end of the shows… but every subscriber (Monthly & Yearly) helps to make this work possible.

All of you rule.

79 Million Views in 6 Months for The Lunduke Journal

Welcome to February, all of you amazing nerds!

January was a fun month for The Lunduke Journal (thanks to all of you). For those interested in a little Inside Baseball, I’ve pulled together some stats and charts below.

The short version: Great month. Crazy news stories. Solid growth. Can’t complain!

Revamped Lifetime Wall

Oh! And the “Lifetime Subscriber Wall” is getting a “retro” facelift.

This is what the four Lifetime Walls currently look like:

 

Once that 4th Wall is filled (a little over 75% of the way there as of this morning), I’ll be introducing the new designs (for all the walls) along with the starting of Wall Number 5.

Each Wall now has its own, distinct look and theme. Very Retro Computer-y. You’re going to dig it.

To make that “Wall Number 5” get here as fast as possible, I’ve gone ahead an reinstated the “$89 Lifetime Subscriber” deal. But only until Wall Number 4 is full.

Want to be on the Wall? If you don’t have a Lifetime Subscription, grab one. If you already have one, email me (bryan at lunduke.com) to let me know how you want your name to be displayed.

Once Wall 4 is full, the Super-Mega-Ultra Discounted Lifetime Subscription goes back to regular price. And, the next day, the new Lifetime Wall design appears at the end of new shows.

At the current rate, I expect that to happen in the next couple days.

Stats for January, 2026

Now let’s look at the stats for January.

Can’t lie. I’m pleased.

  • 30 new shows (just shy of one new show every day)

  • 15.2 Million views (including podcast downloads)

  • 2,326 new subscribers

The most popular story of January, 2026:

Taking a high level view: This means that, in the last 6 months (Aug ‘25 - Jan ‘26), The Lunduke Journal has had:

  • 79.4 Million views

  • 21,694 new subscribers

Bonkers, right?

Here’s a chart of “views” for last 6 months:

Image
 

The long-term trend continues to be solidly upward, with February (in the first 7 days, so far) currently tracking slightly ahead of January.

For those interested in the specific platforms: The Lunduke Journal is seeing the most growth on X and the Audio Podcast.

Here’s a combined subscriber chart for January (up 2,326 subscribers from the month prior):

Image
 

Wild. It is truly amazing to me how widely these stories are spreading nowadays.

Over 15 million. In one month.

These are numbers that most of the big, “Main Stream” Tech Journalists could only dream of.

The reach of The Lunduke Journal, thanks to all of you, is now wildly exceeding any other publication I have ever worked with.

Even though most “Main Stream” Tech Journalists are refusing to cover some of the biggest stories in Tech… those stories are still getting out there.

They are being seen. Far and wide.

Thanks to all of you.

$89 Lifetime Offer Ends at Midnight!

I’ll make this quick: The $89 Lifetime Subscription offer for The Lunduke Journal ends at midnight tonight (Saturday, January 31st).

Once the calendar reads “February” — poof — the deal is gone.

If you wanted to save 70% on a Lifetime Subscription, these are your final hours.

A huge thank you to everyone who has signed up during this crazy deal. We are this close to filling up the 4th Lifetime Subscriber Wall (there’s a possibility it might fill up in the next few hours).

Far beyond anything I was expecting. All of you are absolutely amazing. The Lunduke Journal would not be possible without you.

If you were on contemplating grabbing that Lifetime Sub, I’d jump on it right now. The price goes back up to normal ($300) in about 12 hours or so.

Get it while it’s cheap!
