Hi lutenists,
Leonard Williams asked about security problems in using my "New String
Calculator" in his updated Mac. Because his domain seems to reject posts
from Helsinki University domain, here is my answer, which perhaps
interests also others:
I cannot name any specific reason for your problem, but here is some
general info:
When Oracle bought Java, they ceased to take proper care of the security
issues in Java applets. That is why many - me included - do not
generally allow Java in the browsers. Also many banks have re-programmed
their systems by other tools than Java.
My oldest calculator
http://www.cs.helsinki.fi/u/wikla/mus/Calcs/wwwscalc.html
is in JavaScript, which is totally different from Java, but that page
contains a tiny "sub-calculator" in Java for calculating unknown string
material density. The warning must be connected to that, I suppose.
The New Calc
http://www.cs.helsinki.fi/u/wikla/mus/NewScalc/
is all-in-Java, and much more complicated. It probably contains some
strong Java tools that nowadays can be used to security attacks? Well, I
do know that my program does not anything like that!
If you find a browser that runs this page, there is no harm to come - as
far as I can know. But do not generally allow Java!!
I by myself use only my very light JavaScript version
http://www.cs.helsinki.fi/u/wikla/mus/Calcs/mc.html
It is not as fancy as the big Java version, but works well, when you
know, what you want. And there is no need to worry the security problems.
And remember: Do not allow Java in your browswer, when you go to unknown
pages!
best,
Arto
