  • Regarding “the mechanic always rips me off” - find a good one. When the muffler was loose because of a broken hanger the garage called me, told me and asked me if they should repair it by the book (switching out an 800 Euro part) or just weld the hanger - that would be “The OEM doesn’t allow it, so less OEM warranty, but it’s only Eur 10.”

    They basically asked me to allow them to ignore idiotic OEM instructions. (Yes it was an “official” garage by the OEM)


  • it was an old mechanism in Unix & Linux that flushed “disk writes” to disk. Writes would normally go to the buffer cache in ram and a process called “sync” every 30s to flush out writes to disk. (writing out EVERY change would result in a lot of redundant writes and be very slow, so this was a very simple kind of collecting work until it makes sense to really do it)

    We still write async writes to ram first and then write them to disk later, the mechanism is much more advanced nowadays - and also quicker to start writing.

    Still, on the shell there’s a command called sync which invokes the system call, asking the kernel to flush out all asynchronous writtes.

    (And yes, there’s more than async writes, used by databases for example, but that would require a lot more of explanations)



  • I still remember when I managed to rm -rf / foo (I accidentally typed a space between / and foo) on my very early linux box on the 90s. 80486, 16 mb

    I pressed enter. Saw what I did. Remembered that sync ran at every 30s* Pressed the power button.

    *= those were simple times, but not better times

    So I rm -rf ed my root fs and my box survived it due to the quick power off.








  • My small pizza oven goes to 400C. Everything else is not enough for good pizza. Cooking time for a pizza is 2 to 3 minutes. With that I’ll get a nice leopard pattern on the dough.

    My household oven goes up to 300C but just because it supports pyrolysis. (Best thing, I bought it used from Kleinanzeigen for Eur 50 after about a year of searching for a pyrolysis oven that was sold for cheap). Running Pyrolysis about 4 times a year, so the cost is reasonable but the oven still is CLEAN.



  • The door refused to open. It said, “Five cents, please.”
    He searched his pockets. No more coins; nothing. “I’ll pay you tomorrow,” he told the door. Again he tried the knob. Again it remained locked tight. “What I pay you,” he informed it, “is in the nature of a gratuity; I don’t have to pay you.”
    “I think otherwise,” the door said. “Look in the purchase contract you signed when you bought this conapt.”
    In his desk drawer he found the contract; since signing it he had found it necessary to refer to the document many times. Sure enough; payment to his door for opening and shutting constituted a mandatory fee. Not a tip.
    “You discover I’m right,” the door said. It sounded smug.
    From the drawer beside the sink Joe Chip got a stainless steel knife; with it he began systematically to unscrew the bolt assembly of his apt’s money-gulping door.
    “I’ll sue you,” the door said as the first screw fell out.
    Joe Chip said, “I’ve never been sued by a door. But I guess I can live through it.
