As I've mentioned before, the ultimate goal for my 68030 homebrew systems is to run a proper multi-user operating system. Some flavor of System V or BSD or Linux. I am not there yet. There is still so much I need to learn about programming in general and the intricacies of bringing up one of those systems, plus my hardware does not yet have the ability to support multiple users.

I've toyed with several ideas as to how to get the hardware to support multiple users, but ultimately decided to leverage what I have already. I have a fully-functional modular card-based system. I can easily build new cards to add the functionally I need. And to make development and debugging easier, I can make each card simple, dedicated to a single function.

The catch is I've already run into some stability issues putting everything on the main CPU bus. So what I really need is some kind of buffered peripheral bus I can use for developing the new I/O cards I'll need.

So that's where I started — a new 8-bit I/O bus card that properly buffers the data and address signals, breaks out some handy I/O select signals, and generates the appropriate bus cycle acknowledge signal with selectable wait states.

It wasn't without its problems of course. I made a few mistakes with the wait state generator and had to bodge a few signals.

With my new expansion bus apparently working I could set out on what I had really come here for — a quad serial port card.

I have it in my head that I would really like to run up to eight user terminals on this system. Two of these cards would get me to that point, but four is a good place to start.

I forgot to include the necessary UART clock in the schematic before laying out the board, so I had to deadbug one. I'm on a roll already with this project, I can tell.

So I get it all wired up, I fire up BASIC, attach a terminal to the first serial port, and get to testing.

Nothing comes across.

Step-by-step with the oscilloscope and logic analyzer, I verify my I/O select from the expansion bus card is working, the I/O block select on the UART card is working, the individual UART selects are working. I can even see the transmitted serial data coming out of the UART chip and through the RS-232 level shifter.

But nothing is showing up in the terminal.

I've got the terminal set for 9600bps, I've got my UART configured for 9600bps, but nothing comes across.

I did note something strange on the oscilloscope though. I could fairly easily lock onto the signal coming out of my new serial card, but the received data from the terminal wasn't showing up right. The received data just seemed so much faster than it should be.

Or maybe my card was slower than it should be.

Looking at the time division markings on the oscilloscope, it looked like each bit transmitted was around ... 1.25ms. Huh. 9600bps should be more like 0.1ms. This looks something more like 800bps.

I set the terminal for 800bps and got something, but it wasn't anything coherent, it was just garbage. I wrote a quick BASIC program to sweep through the UART baud rate generator's clock divider setting and output a string of number 5 for each setting until I got a string of 5s displaying on the terminal.

So then I tried sending "HELLORLD".

I got back "IEMMOSME".

No matter what I changed, I couldn't get anything more coherent than that. It was at least the right number of characters, and some of them were even right. It's just that some of them were ... off ... by one.

A quick review of the ASCII chart confirmed the problem.

'H' is hex 0x48, but 'I' is 0x49. 'E' is 0x45, but was coming across correctly.

... I have a stuck bit.

The lowest-order bit on my expansion bus is stuck high. That's why I wasn't seeing any coherent data on the terminal, and it also explains why I had to go hunting for a non-standard baud rate. The baud rate generator uses a 16-bit divisor to divide the input clock to the baud rate. When I tried to set the divisor to 0x0018 for 9600bps, it was getting set to 0x0118 — a difference of 256.

Another quick BASIC program to output the ASCII chart confirmed this was indeed the problem.

Each printed character was doubled, and every other one was missing.

That sounds like it could be a solder bridge. The UART chip has its D0 pin right beside a power input pin. A quick probe with the multimeter ruled that out.

Perhaps the oscilloscope would provide some insight.

The oscilloscope just raised more questions.

Not just D0, but actually several data bus pins would immediately shoot up to +5V as soon as the expansion bus card was selected. As far as the scope was concerned, it was an immediate transition from low to high (it looked no different even at the smallest timescale my scope can handle). If the UART was latching its input data within the first third of that waveform then it certainly could have seen a logic 1, but it doesn't make sense why only the one data pin would be reading high.

I thought maybe it could just be a bad bus transceiver. The 74HCT245 I had installed was old and a little slow for the job anyway, so I swapped it out for a newer & much faster 74ACT245.

And nothing changed.

It's possible the problem could be related to the expansion bus being left floating between accesses. I tacked on a resistor network to pull the bus down to ground when not active.

And nothing changed.

Well ... almost nothing.

This was right about the time that I noticed that while I was still getting the odd waveform on the scope, the output from the terminal was correct. It was no longer acting like I had a stuck bit and I was getting every letter.

Until I removed the scope probe.

Too much stray capacitance, maybe? That waveform does certainly look like a capacitor discharge curve.

I had used a ribbon cable I had laying around to for my expansion bus. It was long enough to support a few cards, but certainly not excessively so (not for these speeds at least). It was worth trying though. I swapped out the ribbon cable for one that was just barely long enough to connect the two cars.

And finally it worked.

Not only was I able to print the entire ASCII set, I could program the baud rate generator to any value I wanted and it worked as expected.

That was a weird one, and I'm still not sure what exactly happened. But I'm glad to have it working now. With my hardware confirmed working I can focus on software for it.

I've started writing a crude multi-user operating system of sorts. It's just enough to support cooperative multitasking for multiple terminals running BASIC simultaneously. It may not be System V or BSD or Linux, but I still think it would be pretty darn cool to have a line of terminals all wired up to this one machine, each running their own instance of BASIC.

Understanding ReactJS – A Beginner-Friendly Guide

Introduction

ReactJS is widely used in various industries, including web development company in Bangalore, which leverage its capabilities to build dynamic and scalable applications.

Imagine a world where building a website is like assembling LEGO blocks—each block representing a specific function. This is exactly what ReactJS does! ReactJS is a powerful JavaScript library developed by Facebook that helps developers create interactive user interfaces in a structured, reusable, and efficient way. Since its release in 2013, it has become a game-changer in web development, powering applications like Facebook, Instagram, and Airbnb.

ReactJS has revolutionized front-end development by making it easier to build large-scale applications with reusable components and a seamless user experience. In this guide, we will break down ReactJS into simple, digestible concepts, making it easy for beginners to grasp and use effectively.

What is ReactJS?

ReactJS is an open-source JavaScript library designed to create fast and dynamic web applications. Unlike traditional HTML and JavaScript, where each change refreshes the entire webpage, React uses a smart feature called the Virtual DOM to update only the necessary parts. This significantly boosts performance and enhances user experience.

Why Choose ReactJS?

Component-Based Structure: Applications are built using reusable components, making development organized and efficient.

Lightning-Fast Performance: The virtual DOM optimizes updates, improving speed.

Strong Community & Support: With a vast developer community, solutions and tutorials are readily available.

SEO-Friendly: Unlike other JavaScript-heavy frameworks, React supports server-side rendering, improving search engine rankings.

Scalability: From small projects to large enterprise applications, React scales seamlessly.

Cross-Platform Development: React Native, a React-based framework, allows developers to build mobile applications using the same concepts.

Core Concepts of ReactJS

1. Components – The Building Blocks

Think of React components as small, reusable pieces of a website, just like individual LEGO pieces. A component can be a button, a form, or an entire page!

There are two types of components:

Functional Components – Simple, stateless components that return UI elements.

Class Components – More powerful components that can manage their own state and lifecycle events.

Components help in modular development, making it easier to maintain and scale applications.

2. JSX (JavaScript XML) – Writing HTML in JavaScript

React uses JSX, a special syntax that looks like HTML but works inside JavaScript. JSX makes UI code easier to read and write, reducing complexity and improving development speed.

3. Props – Passing Data Between Components

Props (short for properties) allow components to communicate with each other by passing data. They help in making components dynamic and reusable.

4. State – Managing Dynamic Data

State is used to store and manage data that can change over time. Unlike props, which are read-only, state can be updated dynamically. This makes applications more interactive and responsive.

5. Virtual DOM – The Secret Behind React’s Speed

Traditional web applications update the entire webpage when a change occurs. React, however, creates a Virtual DOM, a lightweight copy of the actual DOM. Instead of reloading everything, it updates only the changed elements, making applications incredibly fast.

Getting Started with ReactJS

Setting up a React project is simple. Follow these steps:

Install Node.js and npm: React requires Node.js, which comes with npm (Node Package Manager).

Create a React App: Open the terminal and run npx create-react-app my-app.

Navigate to the project folder: Use cd my-app.

Start the development server: Run npm start. Your app will open in the browser at http://localhost:3000/.

This setup creates a structured environment to build React applications efficiently.

Advanced React Features

1. React Hooks – Making Functional Components More Powerful

Hooks allow functional components to manage state and side effects. The useState hook is one of the most commonly used, replacing class components in many cases.

2. React Router – Handling Multiple Pages

React applications often need navigation between different pages. React Router enables this functionality without requiring full-page reloads, ensuring smooth transitions between components.

3. Redux – Managing Complex Application State

As applications grow, managing state becomes challenging. Redux is a popular library that helps manage state in a predictable and structured way, making applications easier to debug and maintain.

4. Context API – An Alternative to Redux

For applications that do not require a complex state management system, React provides the Context API. It allows data to be passed globally without the need for prop drilling, improving code efficiency.

5. Server-Side Rendering (SSR) – Improving Performance and SEO

React supports SSR, which allows content to be rendered on the server before being sent to the client. This enhances page speed, improves SEO, and ensures better user engagement.

Best Practices for React Development

Keep Components Small and Focused: Each component should have a single responsibility.

Use Functional Components and Hooks: They make code simpler and more readable.

Optimize Performance: Use techniques like lazy loading, memoization, and avoiding unnecessary re-renders.

Follow a Consistent Folder Structure: Organizing components, assets, and utilities properly improves maintainability.

Use Error Boundaries: They help in handling errors gracefully without breaking the entire application.

Write Clean and Reusable Code: Reusing components and avoiding redundant code improves efficiency.

Future of ReactJS

React continues to evolve with new features and improvements. Some trends shaping its future include:

Concurrent Mode: Improving performance by allowing multiple tasks to run simultaneously.

React Server Components: Enhancing server-side capabilities.

Better Developer Experience: With updates in developer tools and debugging features.

With strong community support and continuous updates, ReactJS remains a top choice for front-end development.

Conclusion

ReactJS is a powerful tool that makes web development easier, faster, and more efficient. With its component-based architecture, virtual DOM, and advanced features like hooks and routing, it’s no wonder that companies worldwide rely on it.

By learning React, you unlock the potential to create stunning, high-performance web applications. Whether you’re a beginner or an experienced developer, mastering ReactJS will open doors to countless opportunities in the tech world.

With its vast ecosystem, seamless integrations, and continuous improvements, ReactJS remains at the forefront of web development. If you're planning to dive into front-end development, ReactJS is the perfect technology to master.

The My Body Series: A Short Sci Fi Story

Trigger Warnings: Terminal diseases, suicide, self harm, and gore in the name of experimental art

Luthor Pax was a very talented artist. He had a way of bringing emotion to sculptures, most likely assisted by a doctorate in psychology he'd obtained when he was still considering becoming a therapist. He was especially interested in the idea of disassembly, internals, known to take apart engines and hang each component from wires so that it was held up in a similar way to an exploded illustration you'd find in a textbook. Luthor Pax was also dying. His brain was suffering catastrophic damage deep within, inaccessible by surgery or nanites. His paintings and sculptures stopped being of machines, but rather of organisms, disassembled in the same way. It went from animals to intelligent life. Fortunately, he never dissected a real organism. He thought that it would be excessively cruel. One day, Luthor died, leaving instructions to his apprentice, a synth by the name of A7.

A7 took Luthor's body and disassembled it, placing the parts in a massive block of resin, creating a strange display of body parts disconnected from each other, floating in roughly the place they should be, just scattered far apart. It was, of course, a highly disturbing artwork. it was titled 'My Body (Internals)', and it resulted in A7's arrest, though he was later released after it was verified that his actions were legal on Estuary, a planet in the backwater of the outer rim. All this gave A7 an idea. Synths like himself were used to seeing their own parts removed from their body, given their modular nature. In fact, one of Luthor's last experiments was to show synths the disassembled remains of a synth that never had an AI installed, and none were revolted by the sight. Those parts were reassembled into "My Body (Collection)", which was similar in design to "Internals'"

A7 went on to create a lot of other art. Surreal landscapes, strange machines, megastructures looming in the distance. And then, one night, he was found with his visor and AI core shielding removed, with a plasma scalpel plunged into his central processor. The woman who found him fled and looked for help, but by the time police arrived, A7 was gone. And then, a few weeks later, a new art piece was unveiled in the Farbanti Art Museum, in a restricted access gallery: "My Body (Disassembled)". A7's final experiment. He had one last question: if a synth knew that the disassembled parts, though in pristine condition, once belonged to a living synth, would it cause them distress? He wouldn't live to find out, but you have. And the verdict is..?

Well, it appears that some synths can, in fact, look at it neutrally. Even synths with high levels of empathy just don't react to it. A few synths would only be disturbed if they noticed the damage to the AI core. But most synths find it incredibly disturbing. It's a piece that makes a synth immediately aware of the fact that they don't have a gag reflex. It's something you can never unsee. If it's disturbing to you, it shakes you to your very core, traumatizes you. But if it's not, you'll appreciate it for what it is. A collection of parts. Perhaps you'll leave a flower for A7, and you'll move on. And it is a beautiful display of the inner workings of a synth. It's rare to see a synth's body in a way that allows you to examine their organs and how they relate to the whole. That's the beautiful and disturbing nature of the "My Body series".
