Climbing evening.

That was great training - I climbed on vertical wall and tried new traces - complex and not very - 6b, 6a+, eventually 7a, but rubbed fingers completely - that one over tiny holds is really interesting, and I think I can complete it with time. At the end I completed several on-sight traces on the negative slope, but I was already tired enough and did that without the rest in between, so second one (although not that complex at all, 6a only) I fell couple of times, but quite sure I would clearly made that trace if started early.
Also made some old interesting traces, number of traverses - the usual stuff.
I tired as hell, but that worth it. Excellent training.

A hash.

You might now this one:

#define f1(x,y,z)   (z ^ (x & (y ^ z)))

__u32 W[80];
__u32 digest[5];
__u8 in[64];

for (i = 0; i < 20; i++) {
	t = f1(b, c, d) + K1 + rol32(a, 5) + e + W[i];
	e = d; d = c; c = rol32(b, 30); b = a; a = t;
}
