The Path to Full Stack

We are going to do the following in order to make a full stack IoT service:

1.  Install Linux on a small server

2.  Install a web server on it Nginx

3.  Make web pages to serve and put them on the server

4.  Write client side javaScript

5.  Install node.js

6.  Write serverside JavaScript

7.  Write node.j programs that talk to device via serial ports USB

8.  Make a simple device

9.  Make node.js programs to the devices we make

10. Make a link between the web server and the node.js server that talks to the device

11. Make a web page that talks to the device via the web server and the node.js server

12. Install Linux on a small server

13. Install a web server on it Nginx

14. Make web pages to serve and put them on the server

15. Write client side javaScript

16. Install node.js

17. Write serverside JavaScript

18. Write node.j programs that talk to device via serial ports USB

19. Make a simple device

20. Make node.js programs to the devices we make

22. Make a link between the web server and the node.js server that talks to the device

23. Make a web page that talks to the device via the web server and the node.js server

End of the Path

Once the path has been followed, you will have a web server.
You can use your web server in any way you like:

You might use your webserver to show off your gizmos.

OR you might start your own blog

OR you might start an e-commerce site.

It's up to you.

You will also have tools to make IoT devices and other automation devices.

Perhaps this will be where you begin with IoT.

Full Stack

The term Full Stack is an industry buzz word.

When it comes to websites, Full Stack means the code and processes of both the client side, including the web page, and the server side, including web servers and application servers.
Usually, the Full Stack for web sites goes as far as talking to a database server. Application servers talk to the database for such things as authorizing users, listing products, keeping track of sales, etc.
Full Stack software engineers are people who can develop the software in all parts of the web site stack. And, there are plenty of job listings for Full Stack software engineers.

Full Stack for IoT takes into consideration the user interface, which can be web pages, web servers, application servers, and also IoT devices.
IoT devices are such things as sensor boards, robot controllers, etc. that are connected to the Internet. The devices can be connected in a number of ways, e.g. BlueTooth, Wifi, or cables. They can talk to other devices using software defined data formats and protocols such as MQTT, serial tty, HTTP, etc.
Developing software for devices might sometimes be called embedded software engineering. But, often, the person who develops the device's software also has to create interfaces for interacting with the device.

Interacting with devices through web pages requires knowledge of the full stack.

The instructor is an experienced full stack engineer and teacher

Richard Leddy has been a software developer for many years.
For more than forty years, Richard has written full stack services for companies associated with NASA, companies in Silicon Valley, and small enterprise startups. His experience includes Artificial Intelligence, Educational Software, and Business Software.
He has been enjoying subsitute teaching in the Kern High School District for the last several years.

In our device list, there are examples of devices to be purchased for the course.
These are just suggestions. But, they fit sizes and components.
For instance, we are planning to look at a Nano Pi and put it onto a template board that fits a Nano Pi.
We have attempted to keep the total cost of the devices to be around $200.00.

Prices may change. Sometimes devices sell out.
However, a number of devices are quite similar and can be used instead.
Similar devices might have different prices. But, you might prefer them.
Please check the device list to see what kind of devices you should bring to the course.

The emphasis in this course is installation and programming.
Wiring will be minimal and be safe.
We will avoid soldering and the like.

Programming:

Linux Shell Commands:

Linux shell commands are most often instances of the Bash script.
Bash script can be fairly complicated at times; more than it should be. But, for getting a system up, there are a variety of simple commands that a systems administrator should use.
Yes, you will administer your own systems. While doing systems administration can be a full time job, some administration has to be done, just enough, to make a system be operational and do some common tasks.
You will use the Bash script to install web servers and developments tools. You will use it to check on the health of your system. You will use it to update your services. You will use it to start and stop your own programs. You will use it to make sure your networking is working.
We will work with a small number of Bash commands to operate our systems.

JavaScript:

JavaScript was invented for the purpose of programming web pages. You can start programming with JavaScript right inside a browser. You can animate you web pages by writing small JavaScript programs.
JavaScript broke out of the confines of web pages more than ten years ago with the advent of Node.js. Node.js was invented with two basic purposes: 1) Provide a way to write server programs with a language that has a small runtime and that is newer than Bash, PHP, PERL or other scripting languages, many of which are cumbersome and slow; 2) allow web page developers to use one language for their full stack.
JavaScript is now the Swiss Army Knife for the full stack developer. Some companies, such as EBay and Netflix use it to replace Java for their services. When compared to programs in other legacy lanaguages, JavaScript programs tend to be smaller, start up faster, and provide enough efficiency to run their services well. Furthermore, the node.js concept has spawned a few other JavaScript runtimes, including Deno and Bun.sh, which may run faster, start faster, or have better security than node.js.
A lot of Gizmo projects prefer to use Python. But, there is no reason to prefer it for systems level code. Python does run slower than JavaScript and has its own programming style. The AI world has been drawn to it since there are some math libraries associated with it. JavaScript has not been favored with those libraries. But, for AI, there are languages more useful than Python, such as Julia, C++, etc. JavaScript does well for servers and for systems scripting.

For our course, we will concentrate on one language JavaScript.

Basic IoT construction:

We will wire together a sensor board that can provide data to our web pages.

What is an intergalactic identity?

It is a string with a special format derived from a secure hash of content that you make up about yourself.

You may use this identity anywhere that accepts it which means other website and concerns.

How this site uses your intergalactic identity:

This website associates your intergalactic identity with responses to your messages (e.g contact). You may return to this site to retrieve responses to your messages.
You may use your intergalactic identity to start a session with this site (i.e. login).

Your personal information will not be stored on our servers.

Your personal information will not be tied to our domain within your browser storage.

Instead... your personal information will be associated with a virtual URL tied to your identity.

You will be given a personal URL framework page

The links here can help lead you to tools that help open pages within your URL framework page enabling you to work with your personal preferences within those pages.

The pages you open may use personal data by asking your framework page to make requests on their behalf. For example, an e-commerce page will not ask you for your credit card number, but will ask your personal page to carry out a transaction its behalf.

You will have complete control over your personal URL framework page. But, you can maintain it in any way you see fit.

Basically, your personal data will be stored in one place and never leave your browser unless you say so. You will not login to this site, but you may allow the site to log into you - by starting a sessions. The session merely knows you are there and does not ask to know too much about you.
