i have problem ajax callback: 1) in login.html page use: $.post("login.php", formdata, function(data) { } 2) in login.php: echo $data='pass'; 3) problem - on submit event: browser doesn't update login.html callback. instead, displays login.php - white screen 'pass' or 'fail' string, instead of updating login.html page you need use : preventdefault(); $(function () { var yourform = $('#yourform'); yourform.submit(function (e) { $.ajax({ type: yourform.attr('method'), url: yourform.attr('action'), data: yourform.serialize(), success: function (data) { alert('ok'); } }); e.preventdefault(); }); });

i want write wrapper read , write unix functions, read has const void pointer parameter, , write simple void pointer parameter. so, prototype this, fail 1 of functions: typedef ssize_t (*genericstreamhandler)(int, const void*, size); do not prototype function signature if code needs allow incompatible functions. the following compiles without warnings/errors. #include <stdio.h> ssize_t file_read(int h, const void* b, int sz) { if (b) return 0; return h + sz; } ssize_t file_write(int h, void* b, int sz) { if (b) return 0; return h + sz; } //typedef ssize_t (*genericstreamhandler)(int, void*, int); // v--- no function prototype typedef ssize_t (*genericstreamhandler)(); int main(void) { genericstreamhandler gfh1 = file_read; genericstreamhandler gfh2 = file_write; char buf[10]; return (*gfh1)(0, buf, 10) + (*gfh2)(0, buf, 10); } otoh, better answer may lie in taking approach not need common type variant...

i'm doing bayesian inference (manually, using grid search) in python. want calculate probability of each model given data. problem can calculate 'evidence' in log, otherwise 0. so, though between 0-1, can't results for: pr(data|model1) / (pr(data|model1) + pr(data|model2)) since each term 0 in non-log form. any ideas? thanks let logpr1 , logpr2 log(data|model1) , log(data|model2) , respectively, , suppose in [57]: logpr1 = -802 in [58]: logpr2 = -800 if try express probabilities (not logarithms of probabilities), 0: in [59]: np.exp(logpr2) out[59]: 0.0 now want compute log(pr(data|model1) / (pr(data|model1) + pr(data|model2))), which can write as log(pr(data|model1)) - log(pr(data|model1) + pr(data|model2)). for last term, can use function numpy.logaddexp (which essential tip in answer; see scipy.misc.logsumexp ). calculation is: in [60]: logp = logpr1 - np.logaddexp(logpr1, logpr2) in [61]: logp out[61]: -2.12692801104299...

why doesn't c# list<> 's tostring method provide sensible string representation prints contents? class name (which assume default object.tostring implementation) when try print list<> object. why so? the simple answer is: that's way is, i'm afraid. likewise list<t> doesn't override gethashcode or equals . note have little way of formatting pleasantly other call simple tostring itself, perhaps comma-separating values. you write own extension method perform appropriate formatting if want, or use newer overloads of string.join make pretty simple: string text = string.join(",", list);
