Apparently, it IS rocket science.


  • Discourse touched me in a no-no place

    Did you hear the news about the Proton rocket that crashed into the ground seconds after takeoff a couple weeks ago? They found the culprit: someone--a new guy, apparently--installed a number of sensors wrong. They had "this end up" arrows on them, and yet this genius managed to do that wrong. Further, nobody inspected his work.

    In this case, I guess TRWTF is non-keyed connectors.

  • To be fair, it is unusual for "this end up" to define "up".



  • IIRC, another rocket, ten or so year ago, had crashed because some part of the driver were assuming metric measure and other imperial mesures. It was not more brillant.



  • Do you mean this one? Another famous crash (Ariane 5) was caused by the overflow of a variable.

    Conjecture; they were probably installed with those arrows pointing up. The trouble is that they wee installed on a rocket segment which was at that point lying upside down on the construction bench. Nothing looked wrong when they were fitted or inspected, because the segment remained that way up when it was inspected. When the segment was subsequently added to the completed rocket, it was rotated 180° and placed in position, causing the arrows to now point down.

    The solution is to replace "This way up" with "This end points towards the pointy end of the rocket". Or "This way up. And make sure the part you are fitting it onto is the right way up first. Eejit."



  •  In space, there is no up.

    Sure there is. Look down at your feet. See them? Okay, up is in the opposite direction.



  • Even if you're sitting and your feet are perpendicular to your head? Space is awesome!

    Mariner 1 had to be shot down because one of the algorithms for on-board flight control was given to the programmer with a single missing character.

    When I sit, my feet are still pointing down.

    No, the solution is to make it asymmetric so that there's only one way that it fits.

    That's not because of any definitions of up and down, that's because you're a tiny hobbit and your feet don't reach all the way to the floor.

    If you make something idiot proof, someone will just make a better idiot. They will fit it backwards and upside down, from the wrong side of the panel, so that the shape still fits. Or use a hammer. Everything fits when you use a hammer. When mistakes happen, someone gets fired. It's always good to have some grunt to blame when it all goes wrong. If you make it impossible for them to make mistakes, then it's you who will be blamed when something else goes wrong instead. Think ahead, you know.

    I even use a hammer to fire people, so I can skip on all that nasty paperwork.

    If Wikipedia is anything to go by, the orgy of inaccuracy surrounding accounts of that particular episode makes your own contribution ("shot down") rather minor...

    Well, this would never have happened if those engines weren't so damn powerful (IIRC the same variable was used by Ariane 4 with no problem at all)

    What about when you put your feet up?

    These ones are likely relevant to our conversation.

    A customer had bought a computer from us about a year ago and a
    Voodoo 3 card just yesterday. He took it home and tried to install it
    but couldn't, so he brought them both in this morning. He ranted and
    raved, etc. He had reboxed the Voodoo 3, expecting a replacement, so
    we took the computer and the Voodoo 3 in the back and told him we would
    fit it for free. When we opened the box for the Voodoo 3, it was in a
    terrible state. The bit of metal that attaches the card to the case
    was taken off, and a wee heatsink had been scraped off the chip with
    a screwdriver. I reglued the sink and reattached the backplate.
    So we opened the machine, and tried to fit the card. Ack. Card is AGP,
    computer has exactly zero AGP slots. So we went back to the front.

    • Me: "Sir, your computer has no AGP slots, and this is an AGP video card."
    • Customer: "Yeah, but the card fit perfectly into the little white slot."
    • Me: "Which white slot?"
    • Guy: "There's five of them -- little white ones. There's a spare one."
    • Me: "The PCI slot? Uhh...it shouldn't...let me check."

    Sure enough, if you remove the heatsink and backplate, turn the card around, and really hammer it into the only free PCI slot, it will just fit snugly next to the hard disk.

    We explained that the AGP card was completely destroyed and he had voided the warranty on it by hacking away at it with a screwdriver. The usual mad customer vs. techie exchange ensued, but he eventually backed down and bought the PCI version instead...and got us to fit it.

    My mom had some problems with her system and figured she'd get a new modem. After she installed it, there were more problems than before. It turned out the modem was an ISA modem, and she somehow managed to put it into a PCI slot. How, I have no idea.

    @Story said:

    A customer came into the store one day to return an internal modem, which he had purchased a few days earlier. He complained that it would not work. I took the modem out of the package and could scarcely believe my eyes.

    The card had been filed down to about half its original size.

    • Tech Support: "Why has this card been filed?"
    • Customer: "The modem didn't fit in the slot, so I had to file it till it would fit."

    @Story said:


    • Customer: "I just bought a Pentium II 300 from you, and I installed it as the manual instructed."
    • Tech Support: "Let's go over the jumper settings of the board, and make sure all the connections are correct."
    • Customer: "I know that is installed right. I've done this hundreds of times."
    • Tech Support: "Ok, take the CPU out of the slot and reinsert it, making sure it snaps into place."
    • Customer: "The CPU doesn't seem to fit properly. Why don't I just bring this in. You will look at it, right?"
    • Tech Support: "Sure, no problem."

    When the customer brought the motherboard and CPU in, I could not keep myself from laughing. He had installed the CPU into an ISA slot. He had actually cut the housing of the Pentium II CPU to make it fit.

    @Story said:

    • Customer: "Where can I get a BIOS upgrade for by 286 computer?"
    • Tech Support: "The unit should have been shipped with the latest bios."
    • Customer: "Well, I upgraded the processor myself, and my computer doesn't seem to work."
    • Tech Support: "What did you upgrade the processor to?"
    • Customer: "I upgraded it to a 486DX-50."
    • Tech Support: "Sir...the 286 chip is soldered on the motherboard!"
    • Customer: "I know, I took out my handy soldering iron and took it out and put the 486 on myself."
    • Tech Support: "Sir, the 486 is bigger than the 286."
    • Customer: "I know, I had to use quite a bit of solder to solder the extra pins together."

    Wait, so for about 2 to 2 and a half hours every night, subjective up moves from towards the center  of the earth, to west, to towards the sky, to some wierd combination of any two of the above for my fiance?  With, of course combinations of towards and away from her head?  No wonder she's incoherent during and for periods of time afterwards.  The cognitive dissonance alone .......
