Like many non-commercial websites, this site uses advertisements to cover the costs and maybe even make a little profit.

This site is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to

This site uses Google AdSense to serve ads. Read how Google uses data when you use this site.

My books pages link to
Advertisements and other sponsored links on this site will be recognizable as such.
Many, but not all, downloads in the tools/downloads pages are "affiliate links". I try to be as objective as possible in presenting available downloads; if I can earn a buck that's great, if I can't, too bad, but I'll include it anyway.

Note that if you click on advertisements or product links (e.g. books) your browser will navigate to the advertiser's site, which will have its own privacy policy.

Advertisements on this site are served by third-party advertising companies (Amazon, Google's AdSense). These companies may use information (not including your name, address, email address, or telephone number) about your visits to this and other websites in order to provide advertisements about goods and services of interest to you.
If you would like more information about this practice and to know your choices about not having this information used by Google, click here.

Note: Due to performance, security and privacy issues, I decided to deprecate script based ads.
No new script based advertising networks will be added.
If you want to advertise on my site, contact me to discuss the details.


Link exchange

I do not exchange links.

If I think a site may be of interest to visitors of my own site, I will add a link, without any obligation for a "reverse link".

Please do not link to my site unless you think it may be worthwhile for your visitors.



JavaScript is used to support easy navigation through this site.
Without it, there will be a limited menu.

The unit conversion page relies on JavaScript to calculate the converted values.
The demos on the Holidays Calculator and Roman Numerals Converter also depend on JavaScript.

Most pages on my web site can be read with any browser, though navigation may be a little clumsier without JavaScript.

The website analytics and some advertisements use JavaScript.



This site does not use Java.



This site does not use ActiveX, as it would limit access to Internet Explorer only.



On some Windows NT related pages you may get a "popup message" (or dialog) showing extra information, when clicking on a hyperlink.
They are HTML/CSS/JavaScript based and are displayed in the same window.


Browser Compatibility

My goal is to make the information in these pages available to everyone, regardless of the browser or operating system used.
For desktops I think I achieved this goal, but do not expect the same ease of navigation with JavaScript disabled.
Mobile device compatibility is a work in progress... just started, actually.

This site uses JavaScript and CSS for its navigation.
This possibly limits the site to "modern" browsers like FireFox (any), Opera (9 and later?), and Internet Explorer 4 and later....

When I started creating this site, it was still feasible to test each page in most common browser versions. I also used to test each page in 3 different screen resolutions.
Things have changed. I simply don't have that many computers with different screen resolutions anymore.
I do occasionally test the pages on my laptop's 1280x800 screen using SIZER, but though that may change the window size, it doesn't scale down the browser fonts proportionally.
SIZER is also great for (preliminary) tests of mobile compatibility, the final tests are run on my smartphone though.

I test my pages with up-to-date versions of Internet Explorer (on Windows 7), FireFox, Chrome, Iron and Opera on my desktop, and Android's native browser on my smartphone.
If you do run into problems with any of my pages, please notify me at my e-mail address; state your browser version and (relevant) settings and the URL of the page that is causing the problem. I will try to solve the problem as soon as possible.
