It works the same every day, to prepend an o.

Others use temp, temp.sv and then oldtemp.sv but it doesn't generalize.

Re: 2143: "Disk Usage"

How did you know 3 weeks ago that you'd need exactly 19 Os?


19 is nothing. It goes back to last October. A shell script
$ age.sh otemp.mp3=temp.mp3

adds an o to temp.mp3, but if otemp.mp3 exists adds an o to it first, and so on.

Re: 2101: Technical Analysis

In the 50s, secret filters were used to detect cycles, so as to anticipate moves and act ahead of time on them.

In the 60s, people would compute the cycles that the filters were bound to find, in their class on stationary time series.
