Windows command-shell initialisation - if you're used to developing under linux and you want to enjoy some of the same command-line luxuries under windows unfortunately there's nothing you can do to get command-line history beyond your current seesion :-(
rem lines starting with "rem" are commented out similar to '#' in unix-land
rem so you want to have a useful windows command-line?
rem put this file in some standard location like "C:\myscripts"
rem then right-click, "New > Shortcut" and enter the following for location:
rem C:\Windows\System32\cmd.exe /K "C:\myscripts\mycmd.cmd"
rem give it a name you like and then 'finish'
rem then right-click on the shortcut, go to "Properties" and set "Start in:" to be your "Home Directory"
rem I've tried to explain some of the peculiarities of windows "batch-file" and "doskey" scripting below ...

So imagine you have an arbitrary time system in place, where you define time as a number of minutes from a particular date (beginning of your "epoch"), or days from that particular date. If you ever needed to convert such dates to a sensible format, commands such as these could be useful to you. Just add to your environment (e.g. ".bashrc") e.g.…
# set base of 'my' epoch (here it's the start of the 21st century)
export MY_EPOCH=$(expr $(date --date="2000/01/01 00:00:00" +%s))
# format date and time, as expressed in minutes from start of 'my' epoch
function strftime_my {
date --date="@$(expr $MY_EPOCH + \( $1 \* 60 \) )"
}
# format date, as expressed in days from start of 'my' epoch
function strfdate_my {

Java style pseudocode for the remedian algorithm
/* Remedian algorithm rework to use matrices rather than discrete arrays
"""The program of Figure 2 can be easily adapted to produce
the remedian curve, by replacing the arrays A l , A2,
A3, and A4 of length 11 by matrices with 11 rows and T
columns. In this way the total storage becomes 44T, whereas
the plain median would have needed 14,641T positions"""
