I am really skittish about letting computers run overnight unless they were designed to, like servers.
when I was much younger, one day I walked out of the room and the power supply had let loose. it shot sparks up from the fan vent (power supply was on bottom), and the ribbons, ATX wires, etc were laying on the power supply. it caught the wires, and the tower had JUST started to catch on fire. Luckily I heard the POW and ran over there to figure out what happened, and saw smoke.
At that point I had to rush the PC out of there and throw it in the utility sink (living in the basement at the time) and douse it with water.
Fun times. Ever since then, If I am not home or go to bed, the PC gets turned off...
granted thats the only time I have ever seen that happen as far as catching the PC on fire. ive seen many power supply blowouts, but usually the sparks are contained and dont drop hot metal on the wires. But this was around 2002 or so.
Interesting fact, I read an interview a LONG time ago with the guy who developed the original IBM pc for IBM. And, of course he worked for IBM.
One of the questions he was asked was what was the number one design consideration when designing the IBM PC. The interviewer was expecting something like "speed" or "Ease of use", or "cost".
The answer was SAFETY. First and foremost in all IBM designs (at least at the time) was safety.
I forget a lot of you youngsters don't know the history of this stuff. Here is another interesting tidbit from that interview. The reason IBM designed and built the PC:
"Hearts and minds"
At the time "real" computers meant big mainframes - and that was where the money was. IBM did not like competitors hardware in an IBM shop that meant they were losing the "Hearts and Minds" of their customers. There was an old adage at the time. "No one ever got fired for buying IBM." And it was true. If you needed a computer and software there were other choices but IBM was the safe bet.
But mainframes didn't have a spreadsheet and Apple did. For those who don't know this, it was
VisiCalc, the spreadsheet program that REALLY made Apple a success. It was the "killer app", and IBM employees started seeing Apple computers peoples desktops - in IBM shops! and they felt they were losing the "Hearts and Minds". Truth be told IBM could probably have written a spreadsheet to run on a mainframe but it would have been too expensive to run.
So they developed the PC and bought the DOS operating system from Microsoft to run on it.
The part I have never heard explained adequately is why IBM did not enforce their patents and copyrights on the PC. They could have made a fortune. Evidently their focused remained on the mainframe (which by the way has continued to make them a LOT of money),
You got me started- another interesting tidbit.
IBM first went to Gary Kildall of Digital Research, Inc. who had the CP/M (
Control
Program for
Microcomputers) operating system. That was their first choice for an operating system. They literally showed up at his door to talk about it but first IBM asked him to sign a non-disclosure agreement.
He refused.
So the IBM reps flew to WA and talked to Bill Gates, who said "Where do I sign!?"
And the rest is history.
Sigh, another aside, as I understand, the first language Bill Gates learned was in High School and it was BASIC (which, by the way stands for
Beginners'
All-purpose
Symbolic
Instruction
Code - that ain't B4X!). As a result he always had a soft spot for the language which is one of the reasons why it has been kept in the MS fold for so long.
