## Second call for Carnival of Maths articles

**If you have come here from the InsideHPC article and are a little confused it is because they used an incorrect link. The article you are looking for is **Vectorising code to take advantage of modern CPUs (AVX and SSE).

I haven’t had many submissions for the next carnival of mathematics yet and it is due to be published in just over a week. If you would like one of your articles to be featured then please let me know about it via the comments section of this post, email me or use the submission form. Please help me make the 25th carnival one of the best yet.

To find my e-mail address, start with the following and “subtract one” from each letter (for example, you should change the first “n” into a “m”, and so on). There will still be one incorrect letter but it will be obvious what you should correct it to. (I stole this idea from The Math Less Traveled and think it’s a great way to fool the spam bots).

If you have Mathematica then evaluate the following to get it (don’t forget to correct the obvious mistake in the resulting email address)

FromCharacterCode[ ToCharacterCode["njdibfm/q/dspvdifsAhpphmfnbjm/wpn"] - 1]

It annoys me that we have to go to such lengths to prevent spam but such is life.

carnival submission.

I’m just highlighting a neat link I found about classic math mistakes;

Mike,

I hope I’m not too late to try a submission to the Carnival of Mathematics. I can’t tell you how much trouble I’ve had getting equations into my blog. Fortunately, I think me cheat is probably for the best, as it means the solution isn’t readily visible.

Hoping I make the cut. Best wishes, A.

Hi Amanda and Maria,

Thanks for your submissions – both of which will be featured in the carnival.

Hi Mike,

I just sent in a post via the submission form — hope you get it and it’s not too late!

Hi,

just having a browse around and for some reason copied the code above in to mathematica to try. after some initial error messages i eventually figured it out. The minus sign in the code above is some kind of dash, not a minus sign (replaced by your cms?).

Hi David

Yep..you are right – WordPress ruined the code somehow but it USED to work. Bizarre….

Anyway – I have modified the HTML and the Mathematica code seems to work fine now.

Thanks for letting me know,

Mike

Hi!

I have fedora 14 32bit and Ubuntu 10.04 32bit, I have try to install mathematica 8, but Mathematica don’t start, because bottons’registration are as “dead”. What linux distribution can I use ? thanks =)
