In a talk at Columbia last week, Yoav Goldberg mentioned that version 0.99 had replaced version 0.9 of his Hebrew parser. I suggest we use the term “Zeno Version Numbering” to describe such a scheme. I first saw it used for the Lucene index browser Luke, which was up to version 0.9.9 before moving.
Zeno, according to Rick Martin
In the high school gym, all the girls in the class were lined up against one wall, and all the boys against the opposite wall. Then, every ten seconds, they walked toward each other until they were half the previous distance apart. A mathematician, a physicist, and an engineer were asked, “When will the girls and boys meet?”
The mathematician said: “Never.”
The physicist said: “In an infinite amount of time.”
The engineer said: “Well… in about two minutes, they’ll be close enough for all practical purposes.”
