Hi. Any chance to ensure ministat is available in the base image out of the box? Upstream repositories do provide one:
speller/ $ dpkg -s ministat
Package: ministat
Status: install ok installed
Priority: extra
Section: math
Installed-Size: 39
Maintainer: Ubuntu Developers <ubuntu-devel-discuss@lists.ubuntu.com>
Architecture: amd64
Version: 20150715-1build1
Depends: libc6 (>= 2.14)
Description: simple tool for statistical comparison of data sets
The ministat command from FreeBSD. It calculates fundamental
statistical properties of one or two numeric data sets, and
whether a difference can be found between two data sets at a
given confidence level.
Original-Maintainer: Ben Hutchings <ben@decadent.org.uk>
Having it would be nice for making statistically significant measurements (and bringing more fun!) like in the example below:
speller/ $ ./compare.sh
runs: 10
text: texts/tolstoy.txt
running ./speller: ..........
running ./speller50: ..........
my:
x <stdin>
N Min Max Median Avg Stddev
x 10 0.59 0.64 0.61 0.616 0.016465452
cs50:
x <stdin>
N Min Max Median Avg Stddev
x 10 0.61 0.74 0.65 0.652 0.037357135
compare.sh:
#!/bin/sh -e
RUNS=10
TEXT="texts/tolstoy.txt"
rm -f _cmy _c50
printf "runs: %s\n" "${RUNS}"
printf "text: %s\n\n" "${TEXT}"
printf "running ./speller: "
for i in $(seq ${RUNS}); do printf "."; ./speller "${TEXT}" | fgrep -- 'TIME IN TOTAL' | awk '{print $4}' >>_cmy; done
printf "\n"
printf "running ./speller50: "
for i in $(seq ${RUNS}); do printf "."; ./speller50 "${TEXT}" | fgrep -- 'TIME IN TOTAL' | awk '{print $4}' >>_c50; done
printf "\n\n"
printf "my:\n"
cat _cmy | ministat -n
printf "\ncs50:\n"
cat _c50 | ministat -n
Huge kudos for CS50x to all and everyone of you folks! @dmalan @dlloyd09 @CarterZenke
Hi @defanator, we've avoided installing packages that the course itself doesn't use, but we'll soon have a way to automate installation of preferred packages like these!
