Modems and memories

A few days ago, a friend mentioned Galacticomm and their bulletin board system the Major Bulletin Board System.
From the depths of memory, my CompuServe account number and password appeared. And that led me (and now you) on this trip down memory lane.

BBS Systems

BBSs were a big thing once upon a time. Those of you who have only lived in the internet age may find the history of connectivity interesting. Or boring. Whatever.
You could create a BBS system if you had a PC, a bunch of phone lines and an equal number of modems. You might want to start with a PC with a lot of memory. Instead of the 640 KB standard limit, you could get a Phar Lap memory expansion that moved you up to 16 Mb.
That’s megabytes, kids. Not gigabytes. Wow!
Each phone line and modem gave one user access to your system. With a standard PC you could support—well, two users.
But with specialized hardware, you could get up to sixteen.
Sixteen users! At once. All you needed was 16 phone lines and 16 modems.
Wow!

CompuServe

My CompuServe account number and password were. 72520,2747 and GENUS/BUREAU.
Where did that come from? Where had they been hiding? Could I have remembered them if I’d tried? No idea.
But here’s the CompuServe story.
You connected with CompuServe by dialing a local access number, sticking your phone’s handset in your modem’s acoustic coupler.
Acoustic coupler? Don’t know what that is? Acoustic couplers looked like this:
I was an early adopter. I think my first modem was 110 baud. What’s a baud? A baud is roughly a bit per second. At higher baud rates, you can transmit more than one bit per baud, but we never reached them. DSL modems today might.

Doing the math

How fast is 110 baud? If each character takes 8 bits, 110 baud is 825 characters per minute. Some of those characters are channel control, so the effective speed is less. And if your phone line is noisy, even less. But let’s be optimistic and think that it’s about 800 data characters per minute.
An average person can read at more than 200 words per minute—roughly 1000 characters per minute. I’m well above that. So my first modem under best conditions was much slower than my reading speed. Probably slower than yours since you are probably above average.
And images? The picture of the acoustic modem isn’t that big Just 75Kb. That’s 11 ½ minutes at 110 baud. And the megabyte images we’re used to? Don’t wait up.

Faster and faster

Things changed.
Can you imagine how excited we were when the modem standard jumped to 300 baud? Three times as fast. Then, just a few years later to 1200 baud? Four times as fast? Then to 9600 baud. My first 9600 baud modem was big—about 16 inches square and one or two inches high and it cost more than $1,000. And that’s when $1,000 was real money.
Eventually, speeds got up to 56K and sizes went down. 56K modems were on a chip in your PC!
Astounding, right?

Music to my ears

When modems connected, the modem board would let you hear them negotiating protocol, and once they agreed, the board would shut off the sound. If they didn’t, then the sound would go on forever.
This is the sound of progress as modems got faster:
And here’s the full experience for a high-speed modem:

The sound of silence

The sound of modems connecting was music to my ears.
But the sound of silence meant you were connected.
Nothing better than the sound of silence.

Choose the God you believe in--and choose wisely

You can choose the God you believe in. Or you can choose to believe there’s no God. It’s your choice.
There is a fact of there matter. There may be a God. There may be many Gods. There may be no God. What you choose may be correct (consistent with the fact of the matter), or it may be wrong.
But it’s still a choice.
The Marketplace of Religions offers prepackaged Gods to believe in. Many come complete with rites and rituals, instruction books and storybooks, customer testimonials, gathering places, and communities of the like-minded. For those who choose no God, the Marketplace also offers prepackaged agnostic and atheistic belief systems, many with their own accessories.
Within any belief genre, individual believers, leaders, and groups customize the generic offering to meet their own needs and desires and to the demands of the Marketplace for innovation within the confines of brand identity.
The Marketplace gives everyone a lot to choose from.

Is it a choice?

Most people don’t consider that someone can choose what to believe—much less choose which God to believe in; and if they think belief a choice, they don’t think they can make that choice; and if they think they can make it, they don’t exercise their ability. Most people were taught (or more accurately, conditioned) to believe in a particular god, and they never break that conditioning. They accept the choice that was made for them by their parents and other ancestors.
But the God you believe in is undoubtedly a choice. The question to answer isn’t “Is it a choice?” but “Whose choice?” Your choice? An ancestor’s choice? Your community’s choice?
Make it your choice.
And choose wisely.

Choosing wisely

How do you choose wisely?
My answer is: choose the God and choose the practices that will help you to live the best life that you can live. When choosing a God, as in all things, “Believe not what is true, but what is helpful”
If you’ll live your best life being watched by a vigilant and intolerant God who threatens to torture you eternally or burn you to a crisp, then, by all means, choose that God, and live your good life under that God’s pitiless gaze.
If you’ll live the best life being under the loving eye of a God who accepts your failings and forgives your shortcomings, and teaches you the lessons that you need to in order you live the life you desire, then by all means, choose that God and live your good life in that God’s loving embraces.
If none of the prepackaged Gods suit you, you can choose to be creative: design the God that will serve you best, choose to believe in that God, and then act according to your belief.

For me, it starts with gratitude

I am grateful for the circumstances of my life. I’m grateful for the talents and abilities I’ve been given. I’m grateful for other gifts: personal characteristics, tendencies, and opportunities, for intelligence and for health, without which I would not have developed the other gifts I have been given into what I now possess.
I’m grateful for my very existence, for the existence of a world full of beauty and for the ability to see that beauty.
With all the gifts I’ve been given, none of them earned, it would be ungrateful not to say thank you.
But who shall I thank? Shall I thank the laws of physics? Shall I thank the process of evolution? Shall I thank the dark, and cold, empty and uncaring universe from which I emerged?
I need to give thanks, and I’ve chosen a God to receive my thanks. That God is as glad to receive my thanks as I am to offer them.

The God I’ve chosen

The God I’ve chosen is the perfect parent and the perfect friend.
That God is always there for me, available whenever I want company, full of love.
It is a God that forgives my mistakes and encourages me to forgive others as I’ve been forgiven, that loves me and encourages me to love as I’ve been loved.
The God that I’ve chosen doesn’t want me to obey, but to think; to do what is right because it is right and not because I fear Godly or human punishment; to educate myself so I can intelligently decide what is right.
The God that I’ve chosen doesn’t want to be worshiped, but to be loved and respected as one would love and respect a worthy parent or true friend.
The God that I’ve chosen loves and respects me in return.
The God I’ve chosen is the perfect God for me—by design.
That God may exist only in my imagination, but that’s real enough and good enough for me.
And it’s good enough for God.
PS: I believe that God helped me write this. I am certain that any errors are my own.
