For sale page works again

Details
Created: 19 December 2019

Not sure why it was broken (other than my on-going efforts to remove old code that is not PHP7 compatible, and also a recent fix of a security vulnerability) but the for sale page works again. (I thank an alert and patient buyer who, instead of moving on, took the trouble to notify me.) Enjoy browsing, and please do let me know if you are looking for something specific, as I have many calculators not visible here, as I have not yet ascertained their condition, made pictures, or set a price.

Security vulnerability found

Details
Created: 11 October 2019

I thank Khan Janny (@Reboot_Ex) who spotted a cross-site-scripting vulnerability on rskey.org and posted it to the Open Bug Bounty Web site. The vulnerability is now fixed (I hope).

Phantom TI-64 gone from the database

Details
Created: 11 October 2019

There was a Texas Instruments calculator in the database about which I knew nothing. Nothing short of an old post, that is (http://mail-index.netbsd.org/netbsd-ports/2000/03/01/0003.html), which appeared to have described a data entry device that might double as a calculator. Today, I learned that the post was, in fact, an April Fool's joke, posted a month early (or not, if one believes the PS.) So the TI-64 entry is now officially removed from the database.

New models in database: Casio fx-181P, MBO Alpha 610 PR

Details
Created: 17 April 2018

Two new models (well, models that were not previously in this database) were added today: the Casio fx-181P and the MBO Alpha 610 PR. Thanks to Ambrus Zsban from Hungary who brought these to my attention.

500 errors fixed

Details
Created: 25 September 2017

No, the 500 is not the number of errors, but the error code that many users saw when trying to look at lists of calculators by manufacturer, or at individual calculator pages. It appears that as a result of some changes to the innards of Joomla! or one of its components after the latest update, the scripts that generated these listings and individual pages were called more than once, resulting in fatal errors when functions were about to be redefined. Thankfully, Google is kind to us Webmasters: This morning, I received a warning e-mail from Google that many of the pages on this site were inaccessible, and thus, the problem was present only for a few days.
