i using autopairs plugin. if(num==5)//if delete here matching brace further couldn't add matching brace. i want add opening brace.. it's giving me pair of brace. int main() { }//if delete brace further can't add this... if(abs()(num*5))//here after abs want add opening brace //but here coming two. i new in vim.. if elaborately describe solution huge me.. that's odd. usually, bracket plugins let insert closing brackets when it's not next character under cursor. otherwise, can inhibit mapping on demand pressing ctrl-v before closing bracket key.

i have 1d array = [a, b, c...] (length n_a) , 3d array t of shape (n_a, n_b, n_a). meant represent diagonal n_a n_a matrix. i'd perform contractions of t without having promote dense storage. in particular, i'd np.einsum('ij, ikl', a, t) and np.einsum('ikl, lm', t, a) is possible such things while keeping sparse? note question similar dot product diagonal matrix, without creating full matrix but not identical, since it's not clear me how 1 generalizes more complicated index patterns. np.einsum('ij, ikl', np.diag(a), t) equivalent (a * t.t).t . np.einsum('ikl, lm', t, np.diag(a)) equivalent a * t . (found trial-and-error)

my motive current date without caring of system date. my suggestion, if really can't rely on system time use time server. apache commons has useful client this. there plenty of examples online: https://commons.apache.org/proper/commons-net/apidocs/org/apache/commons/net/ntp/ntpudpclient.html there numerous available timeservers. don't tempted correct date in code, fragile , break if corrects server time. the obvious, , easier, solution correct time on server though!

i working in environment contain many liferay newbies along experts, want make configuration prevent 1 modifying structure of liferay database, i.e. 1 developer started liferay 6.2 server while connecting liferay 6.1 configuration database causing database corrupted ... know can't make lr users read-only because change reflected database, want put limitations prevent scenario above.... related configuration available ? regular permissions required accessing liferay's database select, insert, update , delete. when you're developing new plugins need create table, alter table, create index , similar ddl permissions on database you're developing on . don't give them full permissions. update routines (that run when have 6.2 code running on 6.1 structures) require ddl permissions or fail. and, of course, can remove / unconfigure upgrade routines .

welp, thats kind of pointerception. so. im using gtk+ in gtk define buttons this: gtkwidget *button1, *button2; so need function do this. make struct hold pointer it here is: typedef struct userdata{ gtkwidget *button1, *button2; }userdata; i point pointers struct pointers main: userdata data; data.button1 = button1; data.button2 = button2; then use struct gtk event: g_signal_connect(g_object(window), "configure-event", g_callback(resetbuttonsize), &data); and here comes problem. want these variables sent function, example resize them this: void resetbuttonsize(gtkwindow *window, gdkevent *event, gpointer data){ gtkwidget *button1 = data->button; } so like: gtk_widget_set_size_request(button1, 40, 40); sadly, can not (gtkwidget *button1 = data->button;) because following compiler error: /media/dysk250/pmanager/testfile/main.cpp|59|error: ‘gpointer {aka void*}’ not pointer-to-object type| can tell me im doing wrong? im newb...
