I have the adjacency matrix of a graph. I'm trying to find all triangles (embeddings of C_3). This doesn't work: index = function(l) seq(l)[l] pairs = do.call(rbind, lapply(seq(nrow(adj)), function(x) cbind(x, index(adj[x,])))) triangles = do.call(rbind, apply(pairs, 1, function(x) cbind(x, index(adj[x[1],] & adj[x[2],])))) I'm absolutely certain I've gone down the wrong path

One piece of code I'm writing has a lot of intermediates, and I'm trying to optimize down the number of memory accesses. Here's a snippet from the start of the function, where I think there is some low-hanging fruit: # BB#0: pushq %rbp pushq %r15 pushq %r14 pushq %r13 pushq %r12 pushq %rbx movq %rdx, %rcx movq %rdi, -16(%rsp) # 8-byte Spill movq (%rsi), %rdi movq

I'd like to convert a dist into a table/matrix/thingy of the form: A B value A C value B C value (assuming the dist was over 3 names). Is there a way to do this without using a for loop? -- Taral <taralx at gmail.com> "Please let me know if there's any further trouble I can give you." ? ? -- Unknown

Please change all longs to int, and never use them in the future :) They arent needed as on most platforms they are the same size. (which is the assumption made in the ogg code anyway) The reason for this is i will have vorbis support on playstation 2, but long is 64 bits, and they are excruciatingly slow. cheers Brett Paterson --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg

...g on my gentoo vps. i managed to use emerge to install icecast, which was way easier than when i tried on cent os last year. this is running perfectly, starts on boot etc. the only version of ices thats available via emerge is ices2, which i dont want. ive tried (and im no linux pro) wget the tarall, unzipping and compiling it, but i get this error when i try run ices: _JUNGLISED ICES-0.4 # ICES -C /USR/LOCAL/ETC/ICES.CONF.DIST -B_ _BASH: ICES: COMMAND NOT FOUND_ im at a complete loss now. I just cant figure out how to get it running. Anybody had better luck getting it working on gentoo?...

I saw some mail go by a bit ago about doubles-vs-floats, but I seem to have lost it. I'm interested in rewriting the mdct code using Altivec on MacOS X. Altivec doesn't support doubles, though -- the only floating point vector type is single precision floats. Vorbis currently has doubles everywhere -- is this really necessary? Doubles are supposedly faster than floats in the PPC

Hi, I don't really know the details of the discussion, but I'd like to present this issue from a user-oriented perspective, and from the perspective of how Nautilus wants to use data files. In brief, Nautilus makes the assumption that the mime type is sufficient to pick the right applicatiob or pluggable component to view/edit a particular content type. This is quickly coming to be the

Here's the code and compilation steps: #include <stdint.h> typedef unsigned int uint128_t __attribute__((mode(TI))); typedef struct{ uint64_t l[5]; } s; void f(s * restrict r, const s * restrict x, const s * restrict y) { uint128_t t[5] = {0, 0, 0, 0, 0}; #define BODY(i,j) { int i_ = i < j ? i : j; int j_ = i < j ? j : i; uint128_t m = (uint128_t) x->l[i_] *
