Thanks for keeping me from going crazy — very useful! Makes me remember how frustrating programming before google used to be

Thank you for this post ! I also solved my bug ! It was also working on 2.5 but stopped working on 2.6. I think it is stricter in garbage collection. Keeping a global or instance reference to the callback solves the problem.

Thank you,

Comment on Visualizing group structure with colored addition/multiplication tables by Steve Souza

Interesting. I created a simple java program a while back that allows you to put in any number you want to use as the modulo. The results are drastically different depending on what you pick. Also it generates some images using a tangent function. The code and a couple examples of what is generated are attached. The modulo images seem to have been removed though…

Brilliant! Most of the time I replace a good bit of the comments.php anyway but this is perfect for those quick projects where I just need it to work threaded quickly.

@andrewl:

You’re right, I’ve messed up I should’ve mentioned something like DSA instead.

Your idea is neat, I’ll try it later and post it. Thanks for reading!

“Then I got curious: how would the multiplication table of integers modulo n look like? This group is the group used in many cryptographic schemes, like RSA. This is the multiplication table for integers modulo 509:”

Well where is the n? 509 is prime!

If you draw a picture of the group Z_n*, it would be very cool if you could draw by its side Z_p* and Z_q* and then use the same colors in Z_n* somehow so that we could see the “direct product” of the two groups.

I’ll keep watch on this page! Very nice!

Thank you for this excellent solution for threaded comments with Sandbox. It works great!

Too bad Sandbox is no longer supported.

Thanks man for your effort.
I’m doing a hardware implementation of Shamir’s Secret sharing as a Senior project. This post and the Montgomery one were very helpful.

Keep it up!
