/zir-ō/

vt. 

  1. To set to 0. Usually said of small pieces of data, such as bits or words (esp. in the construction zero out).
     
  2. To erase; to discard all data from. Said of disks and directories, where zeroing need not involve actually writing zeroes throughout the area being zeroed. One may speak of something being logically zeroed rather than being physically zeroed.

    See scribble.

/zen/

vt. To figure out something by meditation or by a sudden flash of enlightenment. Originally applied to bugs, but occasionally applied to problems of life in general.

"How'd you figure out the buffer allocation problem?"

"Oh, I zenned it."

Contrast grok, which connotes a time-extended version of zenning a system.

Compare hack mode.

See also guru.

/zap'd/

adj. Spicy. This term is used to distinguish between food that is hot (in temperature) and food that is spicy-hot. For example, the Chinese appetizer Bon Bon Chicken is a kind of chicken salad that is cold but zapped; by contrast, vanilla wonton soup is hot but not zapped.

See also oriental food, laser chicken.

See zap, senses 1 and 2.

/zap/

  1. n. Spiciness.
  2. vt. To make food spicy.
  3. vt. To make someone suffer by making his food spicy. (Most hackers love spicy food. Hot-and-sour soup is considered wimpy unless it makes you wipe your nose for the rest of the meal.)

    See zapped.

  4. vt. To modify, usually to correct; esp. used when the action is performed with a debugger or binary patching tool. Also implies surgical precision.

    "Zap the debug level to 6 and run it again."

/yü-shyäŋ hōl fish/

n. obs. The character gamma (extended SAIL ASCII 0001001), which with a loop in its tail looks like a little fish swimming down the page. The term is actually the name of a Chinese dish in which a fish is cooked whole (not parsed) and covered with Yu-Shiang (or Yu-Hsiang) sauce.

/yō-yō mōd/

n. The state in which the system is said to be when it rapidly alternates several times between being up and being down. Interestingly (and perhaps not by coincidence), many hardware vendors give out free yoyos at Usenix exhibits.

Sun Microsystems gave out logoized yoyos at SIGPLAN '88. Tourists staying at one of Atlanta's most respectable hotels were subsequently treated to the sight of 200 of the country's top computer scientists testing yo-yo algorithms in the lobby.

[from the standard disclaimer attached to EPA mileage ratings by American car manufacturers]

  2. A qualifier more generally attached to advice.

    "I find that sending flowers works well, but your mileage may vary."
