Christian Remnant Now / ๐Ÿ’ป Unix

My son, fear thou the LORD and the king: and meddle not with them that are given to change: Prov 24:21

I am what one would call an โ€œold school hackerโ€. Not like you see portrayed in the movies, breaking into government computers and stealing information. But real hackers are folks who like to learn about technology and modify it for their own use. Any technology, not just computers. I worked for 30+ years with Unix systems. Now I just handle mailing lists for a printing company, in North Dakota (not much tech here).

But I still love to use UNIX/Linux (I will mix the terms going forward, get use to it). I write code for my personal use, just for fun. I also maintain this website and use it to study the Bible. see About

Side note: Background is โ€œgreen-barโ€ like the old computer lab paper.

UNIX - A computer operating system

Those who do not understand Unix are condemned to reinvent it, poorly.

Why I like Unix

I was thinking about this today (7/27/2021), as I was changing the โ€˜lmโ€™ script. I donโ€™t even remember the place I got it from anymore. But I used it and thought it was handy. Then I wanted some color, so I changed it. Then I wanted mp3 files supported. Next I added a total play time. This last mod happened when I tried to point to another directory and it did not support it.

It (Unix) allows me to do what I want, the way I want it, when I want it. Its free, powerful, not a resource pig, and once you master the shell, you can do just about anything you can think of. It puts the power in the users hands.

I started this website with some basic understanding of HTML, and decided to use Markdown to keep it simple. The more I worked with the site, it became a hassle. So I wrote some scripts, (site and web) to manage it. Then modified .vimrc to support Markdown macros I wanted. Now it takes me a couple of minutes to manage the site. Most of it is completely automated.

Oh, and the cost? FREE!

See: Introduction to Unix/Linux for more information as to why you should consider it.

I have been using UNIX or some variant of it for most of my life. I have used many flavors over the years. This is a sampling of my personal favorites:

๐Ÿ–Š Markdown

A simple markup language that can be used with Vi (or Vim)

This is what I use to maintain my website, keep all of by notes (technical, Bible, personal), and write in. It can be easily converted to HTML, PDF, docx, etcโ€ฆ

๐Ÿ“œ Some of my scripts

Where there is a shell, there is a way.

Web scripts used to create and mange this site

This website is made from markdown files. I wrote the following scripts to make it easy for me to manage it. I often change them when I think of a better way to do something, or to address an issue I run into. Like all of my scripts on this page, I did not write them for public consumption. With that said I have attempted to keep them readable, and commented. A lot of them will auto install requirements with apt. This is because I can copy them and have them work without much to think about on my side. Please note: I use Pandoc as the back end for markdown conversion.

Side comment: I do not have ANY CGI, the entire site in static, manually updated with the scripts below. It cracks me up to watch my logs (lnav), and see all the hacking attempts. People really want to take this site down. They go after, PHP, SQL, WordPress, MySQL, and more.

Note: To see the source for the pages on this site change the โ€˜.htmlโ€™ to โ€˜.mdโ€™, if the URL does not display anything other a directory name, use โ€˜.mdโ€™ added to the directory name: http://crn.hopto.org/unix.md

DosBox

I used Dos back in the day and I decided to build a DosBox environment to run some of the classics

You can run DosBox on Windows 10, Linux, and even on Android.

Console Screen Savers and Wrapper

I hang out in the shell all the time and so have come up with a way to have a โ€˜screen saverโ€™. It is manually called by a script called โ€˜sโ€™ (why type more?). My โ€˜menuโ€™ script listed above has a timeout value, so if you do not select anything, it will auto run โ€˜sโ€™.

Games scripts

I have collected a little sample of some of the better games written in scripting languages. I have enjoyed using them over the years.

If someone with better perl skills want to add a ending (win/loose) to this, send me the updated one to post.

Code

struct ComputerContractor
{
    double    salary;
    long      lunches;
    float     jobs;
    char      unstable;
    void      work;
    int       hiring_him_again;
    const     pain_in_the_arse;
    unsigned  agreement;
    short     fuse;
    volatile  personality;
    static    progress;
};

Unix is user-friendly, itโ€™s just picky who its friends are.

Windows and Mac users

Having had to work with Windows as a required desktop for work, I have found the best terminal emulation is called Zoc. It alows you to automate anything, any way you can conceive threw your terminal. This is THE biggest help I have ever had over the years for managing large amounts of servers.

It is a commercial program, but well worth the money. One of only two that I own.

The other one worth looking into is ExpandDrive. This will let you map UNIX/Linux volumes as network drive for full read and write. Plus cloud based volumes as well.
