Really Know Why It Is Called a Computer Bug?

05/18/2016 10:45 PM

Don't think I have ever seen this here (apologies if I missed it)

We could all use another history lesson......Thank you Grace Hopper!!

When you get a bug you fix it and re-boot.

So, where did "re-boot" originate?

It's short for bootstrap which is a shortened version of bootstrap load apparently. The re part should be obvious.

I remember working with an early computer at school. We first had to teach the computer what to do using the "bootstrap" paper tape.

Yup, that's right. The origin of the word 'Bootstrap' to mean 'the program you load so the computer can load and run programs' came from the old phrase 'to lift oneself up by his own bootstraps,' which described a 'self-made man,' providing the mental image of someone who could get out of a pit by picking up his shoes and tossing them out of the hole while still wearing them.

The 'boot program' has nothing to do with 'boot to the head,' which many of us would like to give to our computers when they malfunction, if we could work out what constitutes the 'head.' Is it the monitor, where the 'face' of the computer is, or is it the box, where the 'thinking' is done? And if we do successfully give a computer a 'boot to the head,' when the Mighty Robotic Overlords take over, will they punish us for it?

In the early days of computers, the kind that took rooms filled with tube based circuits that are all transistorized now, there were problems that were traced to tube failures caused by moths. Just like now when they fly around light bulbs on a summer evening, they would fly and crawl around the tubes until they eventually became an unintentional part of the circuit.

That is the story that I heard in my EE classes decades ago. Perhaps it has changed.

Moths and light bulbs kinda reminded me of this skit.

My computer is under my desk. I "boot-up" by hitting the power button with my toe.

I heard Grsce Hopper speak at my girlfriend's graduation. She is the originator of the phrase, and it was literally a bug in the computer that caused it. She was a fascinating speaker.

Another bit of G.H. trivia, she had all the clocks in her dep't running backwards (along with the numbers) just so people would have to pay attention.

Cool! Must have been quite some time ago. I remember seeing those clocks that ran counterclockwise. I always wanted one of those clocks but they seem to have fallen out of fashion. I always thought they were designed to force a different perspective such as thinking outside the box.

I've seen only one clock like that. It was in the Plutonium fabrication building at ANL. Would be interesting to know where they could be obtained.

Re: Really Know Why It Is Called a Computer Bug?

Through comment number 12, a point is missing or misinterpreted. I know because I used to scrounge parts from early computers in the 60's, that relays were used VERY extensively in them, and I know from actually reading a copy (certified by the US Navy as true) of Grace Hopper's log books while I was in my ET/CT training programs that the issue was a "bug" (a crispy moth" in a relay's contacts, which caused an erroneous calculation.

So, not from flying around vacuum tubes. Rather from crawling into an open frame relay's contacts. Don't ask me why. Maybe they liked Ozone.

I also know, because in the High School I attended in 1968-1972, where we programmed in Binary, and I ran the Hollerith Coding Punch Card Machine between classes and after school (Cause they let me. Why else?), we programmed for an IBM machine (Actually, it was a 5 or 6 story building, and the computer took up the whole building. I kid you not. We visited it, and saw how much space the computer took up), at the IBM building, not 1/2 mile from our school. That sucker was FULL of relays. and all of them were large, open frame types.

BTW, we learned to build flip-flops with two tubes, and various capacitors, resistors, etc, each on it's own circuit board. Built our own, using phenolic resin boards and LOTS of little metal standoffs and connector points. We thought we were pretty spiffy when we could put together enough flip-flops to build an 8 bit cascade counter, with a time delay clock, so that the fancy little light bulbs and the loud, clicky relays (Almost all scrounged from a bowling alley that went out of business. Amazing what we could scrounge from bowling alleys in the early days of Art Deco scoreboards.) would move the one-bit down the wall.

The girls weren't into geeks yet, but we thought we were really something. No one else in the school had any idea how we did it. Of course it helped the we also knew (thanks to being geeks) how to fix, and raid, the food vending machines (After all, all THEY were was assemblies of relays and ramps, with motors. Not a flip-flop among them.) in the school quad.

Glory days. No girls, but lots of junk food! And we had ALL the secrets. Especially those of us (not naming names, here, but I DID work as a commo contractor for the CIA after 9 years in the Navy's spook shops) who built and installed our own telphone bugs (Analog equipment? Child's play. No big deal. Certainly since no one had any idea it could even be done back then, let alone that a High School kid could do it.)

So, Admiral Grace Hopper is my Hero(ine) (If that's not TOO PC for folks here.) and I paid a lot of attention to what she said/knew/taught us through her story and her log books.

You reminded me of my college days - late 70's - I was in electronics and just getting into TTL logic. The computer programming class was across the hall and we thought they were all secretaries......

But I also worked evenings at a Radio Shack in the mall. A gentleman came in (obviously waiting for his wife to finish shopping...) He was looking at the hand held calculators in the case and started telling me about his brother in Washington DC. He worked in a room as big as the store filled with electronic gear and said it was a computer that could add, subtract, multiply and divide. To top it off, he told him that in 20 years you could get the same thing but it would be as big as a suitcase!! Of course he thought his brother was crazy! And here it was 20 years later he was looking at the scientific calculators.

Such amazing progress!!

The first scientific calculator I bought was an H-P that cost $259.00 a year later I bought the same calculator in Sears for $59.00. Within 2 more years I could get calculators that were smaller and could do more for as little as $29.00. All this from a 6 story building that was one computer that needed a special method of feeding data in and out.

Cleaning squashed insects from the contacts on open relays in early computers.
