What’s New at OakRoadSystems.com
Copyright © 2002–2017 by Stan Brown, Oak Road Systems
This page helps you survey the significant changes to the Oak
Road Systems Web site.
While any change to a page automatically changes its revision date in
the site map, this What’s
New page is
prepared manually and does not list minor changes.
Add several new sections to Windows 7 Tips and Tweaks.
Use similar “donate” links to
BrownMath.com. Add a
landing page for people working from
printed copies who want to donate.
Post the GENER8 script,
which I use to generate all these Web pages. During the month,
remove system dependencies so that the code should now work in UNIX as
well as Windows; see all
Update the Link Exchange
All my current math pages are at
but Math Sites and Software won’t move there. With
Internet search engines so good, a static page of links seems so 20th
century. I’ll leave it in place for anyone who has bookmarked
it, but I’m not going to update it any further.

launched on 10 May. All math articles from OakRoadSystems.com
will eventually move there, but for now I’ve added links from
the site map,
home page, and
main math page, plus a
BrownMath option on the
Google search page.
- First public release of
Tears. This is a full textbook, covering a first course in
statistics, with exercises, and it’s a free resource, at least for
What with surgery in the summer and a long aftermath of
recovery, I wasn’t able to do any significant
updates. But now I’m starting to catch up with the backlog:
- More tips in Windows 7 Tips and Tweaks.
- New links, and correction or removal of dead links, in
Math Sites and Software.
- Finally! Tables of contents no longer have <table> tags, or
<br> and for layout, but are now all lists with CSS
- Withdraw Web Resources for Web Authors, which was
horribly out of date.
- Withdraw the WHISTLE shareware program, which used the PC speaker to
play a tune with no need for a sound card, because hardware and OSes
prevent it from working.
- Replace the separate print and screen style sheets (31 K in
aggregate) with a unified style sheet
(13 K). You may not notice the performance improvement, but it
will cut the site’s bandwidth significantly.
- Consolidate separate TI-83/84 programs for several descriptive
statistics procedures into a single
MATH200D program, along with new programs for plotting time
series, making box-whisker plots, and plotting the histogram of a
binomial probability distribution.
- Remove Skewness and Kurtosis on the TI-83/84;
the calculator part went
into Descriptive Statistics Utilities for TI-83/84 (now
incorporated in MATH200B Program — Extra Statistics Utilities for TI-83/84) and the statistics part,
rewritten and expanded, became the new article
Measures of Shape: Skewness and Kurtosis.
- Rewrite the rules of thumb for
means and standard deviations.
which has since moved to BrownMath.com.
- Consolidate separate TI-83/84 programs for several inferential
statistics procedures into a single
MATH200I program, adding a new option for computing sample
- Add Skewness and Kurtosis on the TI-83/84 and a
TI-83/84 program (but see Dec 2008 for later history).
- Add “Frequency Polygons on the TI-83/84” and a TI-83/84 program
that makes frequency polygons and histograms.
- Consolidate the page on making a histogram for a list of numbers
and the page on making a histogram for a grouped frequency
distribution into a single page “Histograms of Numeric Data on
- Update the tip on sorting files numerically in
Windows XP Tips and Tweaks.
New math pages:
Updated the titles of several more pages to match changed
- Donations are now tracked by which page’s
“donate” link you clicked.
- Converting CDs to iTunes Audiobooks is now complete, after being published in March as just
- Another ten pages for
mathematics students at Tompkins Cortland
Community College (TC3) are now incorporated in this site.
- The new page Play Nice in Email, adapted and expanded from
my TC3 site, explains why HTML is bad in e-mail and how to set your
mailer to deliver plain text.
- Release 5.23 of CMP handles
path\filenames of any length, even those longer than the documented
259-character Windows limit.
- Play Nice on Usenet now
starts with some links for people who aren’t quite sure what this whole
Usenet thing is.
- Release of CMP 5.2. New features
include showing just the lines from one file that weren’t in the
other, and comparing the output of a program (redirected
stdin) to a reference file.
- Release of GREP 8.0. It
handles all types of text files in line or paragraph mode, as well as
binary files. New output formats are available at your discretion.
- Play Nice on Usenet
gained a few
- Having found that an astonishing 40% of this site’s bandwidth
was the style sheets (CSS files), I squeezed out unnecessary spaces and
