How could they achieve this with much abstraction?

I know it makes no sense about what I'm going to say but: whenever I lose a 'simple 5G phone call' connection I remind myself that the Voyager 1 runs on 69kb of memory and there's a robot on Mars.

We are so detached from the software "engineering" in our jobs that we are amazed when we see it.

Wish javascript devs would read this. If the web is slow, its because of them

What happens when hydrazine tanks run out and it can't stabilize anymore to shoot data back to earth? it's over?

I knew about the memory, but an 8-track tape ? That is a surprise. But when you think of it, what else could you use for this in 1977.

What amazes me is the tape lasted almost 30 years. I knew tapes back then could last a while, 30 years being bombarded with cosmic rays ? inconceivable :)

A tape with eight tracks, yes. But not the audio cartridge format commonly known as "8-track"; that wouldn't have been suitable to the task. Here's a photo:

An old 1970's arcade game, Quiz Show, used an 8-track tape to store the questions and answers. There's a YouTube video about it, and audio dumps of the 8-track on archive.org I think.

Yesterday I loaded a program on tape bought at Radio Shack in 1985 into my TRS-80.

That's 41 years ago.

I suspect the key is using commercial-grade recorders and thick tape.

I suspect the key was you used Dr Emmett Brown to tune up the equipment then plugged your electric guitar into his amplifier.

> For the first time in the history of the universe, as far as we know, an object built by a living species had left the protective bubble of its home star system...

Seriously?

An easy claim to make if you only check with species from one star system

Which other species in what other star systems do you suggest we check with?
