is there linear algebra library implements iterative gauss-seidel solve linear systems? or maybe preconditioned gradient solver? thanks edit: in end used kind of crude correct way solve it. had create matrix (for ax=b) anyway, partitioned matrix a = m - n with m = (d + l) , n = -u where d diagonal, l lower triangular section, , u upper triangular section. then pinv = scipy.linalg.inv(m) x_k_1 = np.dot(pinv,np.dot(n,x_k)) + np.dot(pinv,b) also did convergence tests. works. there example implementation go through various implementations here: http://www.scipy.org/performancepython another example here: http://www.dur.ac.uk/physics.astrolab/py_source/kiusalaas/v1_with_numpy/gaussseidel.py you might want check out python bindings petsc : http://code.google.com/p/petsc4py/

currently have local subversion repository lot of commit messages in cp1251 encoding. is there way can convert commit messages utf-8 encoding? your commit messasges are stored utf-8 : subversion internally handles bits of data—for example, property names, pathnames, , log messages—as utf-8-encoded unicode. not interactions subversion must involve utf-8, though. general rule, subversion clients gracefully , transparently handle conversions between utf-8 , encoding system in use on computer, if such conversion can meaningfully done (which case common encodings in use today). if you've somehow double-encoded them, though, assuming you're using fsfs-style repository easiest way work through revprop files find in db/revprops/*/* underneath repository , re-write them correct encoding, e.g. using iconv command-line tool gnuwin32 . (note these files should have unix line endings i.e. lf not crlf).

i trying let users login website using facebook account. have tried reading information related process facebook developers (http://developers.facebook.com/docs/) page - while process , logic sort of make sense, still lost regarding big picture. how 'facebook connect' link existing database of users , attributes. there user called john walker, registered user (login: jwalker pass:1234 account balance:$10). when come website, , try login using facebook login, how know direct him? in other words, how facebook know right john walker, , should sent user page? i sorry if question trivial, can't think though myself. in advance! zachary well zachary, have little bit misconception regarding facebook connect. when user clicks on facebook connect button placed on site, facebook doesn't go database authenticate user. authenticates user in database whether current user having facebook account or not... if he/she having account facebook issues access token particu...

i'm looking have fscanf identify when potential overflow happens, , can't wrap head around how best it. for example, file containing string **a**bb**cccc** i char str[10]; while (fscanf(inputf, "*%10[^*]*", str) != eof) { } because i'm guaranteed between ** , ** less 10. might a **a**bb**cccc* (without last *) or potentially buffer overflow. i considered using while (fscanf(inputf, "*%10[^*]", str) != eof) { } (without last *) or even while (fscanf(inputf, "*%10s*", str) != eof) { } but return entire string. tried seeing if check presence or lack of *, can't work. i've seen implementation of fgets, i'd rather not make complicated. ideas? i'm not clear on want. skip on number of stars, , read 9 non-star characters buffer? if so, try this: void read_field(file *fin, char buf[10]) { int c; char *ptr = buf; while ((c = getc(fin)) == '*') /*continue*/; while ...

this not php question, expertise php frameworks. a lot of frameworks have bootstrapping (loading of classes , files) mechanism. (drupal, zend framework name few) everytime make request, complete bootloading process needs repeated. , can optimized using apc automatically caching intermediate code the general question is: for language, there way not load complete bootstrapping process? there way of "caching" state (or starting at) @ end of bootstraping process not load again? (maybe answer in other language/framework/pattern) it looks me extremely inefficient. in general, it's quite possible perform bootstrap / init code once per process, instead of having reload every request. in specific case, don't think possible php (but knowledge of php limited). know have seen criticism of php's architecture... fair php, it's not language or framework things way. go detail... the style of "run every request" came "cgi" script...
