Just make sure that a GPU miner can't be made easily. *Points at XPM*
Nice, this is turning out quite well! Thank you to all for your support!
I was just wondering if there was a way to implement the "parabola" part!

One thing I've realised. All of the AES candidates are based around encryption from a key. If we go for a quark-style hash system, then if we are being secure, we need 14 different keys.
Something for donators to suggest?

If you want to. I'm not forcing you to.

Are we doing the random hashing algos too? (like first sha, then whirlpool, then md5, then random, then random again)
As far as I can work out, each pass of Quark's "random hashing" simply checks whether the least significant 3 bits in the second most significant 32-bit word are zero. If they are, then it runs one hashing algo, else, it runs a different one. It screws PGO massively.
I like your idea, but I think we can make a different scheme which makes optimisation even more awkward.
Some pseudocode:
Code:
void Hash(int* input, int* output)
{
imt mask = 8;
int i = 0;
for (; i < 8; i++) {
switch (input[5] & 8) {
case 0:
Rijndael(input, input);
case 1:
Square(input, input);
case 2:
Serpent(input, input);
break;
case 3:
RC6(input, input);
case 4:
MARS(input, input);
case 5:
Twofish(input, input);
break;
case 6:
Twofish(input, input);
case 7:
Rotate256(input, input, 3);
}
memcpy(...);
}
{
imt mask = 8;
int i = 0;
for (; i < 8; i++) {
switch (input[5] & 8) {
case 0:
Rijndael(input, input);
case 1:
Square(input, input);
case 2:
Serpent(input, input);
break;
case 3:
RC6(input, input);
case 4:
MARS(input, input);
case 5:
Twofish(input, input);
break;
case 6:
Twofish(input, input);
case 7:
Rotate256(input, input, 3);
}
memcpy(...);
}
That ought to make GPU mining difficult. With up to 24 rounds of pseudorandom hashing algos, and a rotate in there for good measure, it may well make CPU mining difficult, too.

I'm bumping for services and devs. Remember, if you contribute you will be given a share of the 5% dev fund.

May I be a contributor? My username is Smeagol-Gollum on github.
Edit: I submitted a couple of pull requests, you should see me now!
Merged.
Matthew:out
Seriously, forum? I post three times in a row and it still doesn't accept the post
I will download the repo and do a find and replace from bitcoin to parabola
Hmm. I tried to submit a pull request to merge but instead I just forked it onto my account. (here: https://github.com/Smeagol-Gollum/parabola)
All the names are changed. If you can, please download the .zip and add it to your repository! I don't know how to merge them.
Merge conflict.
Given the blatant find and replace, I did it manually. This does throw all of your commits off track of the master, so the best thing to do would be revert them, then do a fresh pull on master.

Shoot me a PM when you think Parabolas are ready for an exchange. I can pull some strings 
Thanks! Will do.

I have personally purchased a VPS to be used as a node. $4.05, paid in BTC. Over half the amount of BTC that I have mined.

Matthew:out
Thank you! Hopefully the coin will compensate you and get back your BTC! (open source devs never get paid, maybe this could be like DVC)
Well, it expires on September the 25th, so we'd better be quick.
VPS donation address (not owned by me, but by the VPS company): 16F3yJyqfEZFAFwct97qcB71Cxn2QwCMJu Every BTC0.03531258 is another month on the VPS.

As for coding, would it be good to create a github repo and have forum members submit pull requests?
You mean like this?

Why are other people reserving? (Not just OP and Matthew)
Thanks!
Not sure but it happens on all the new coin announcements, first two pages get a bunch of reserved posts. I think it is so they can come back later to edit the post and have what they want to say on the front page
