i'm wondering how optimise ansible work network radically different 1 use cases accelerate , default might not beneficial. in scenario i'm not dealing virtual network, nor dealing servers. i'm dealing hundreds of embedded, rather unique network design, downside of faults in hosts or cabling on network may cause periodic connectivity changes neighbouring hosts. this result in dropped or laggy ssh sessions on individual ssh conneciton, unfortunately cause ansible hang on particular hosts , timeout change alone doesn't seem make difference. could provide information parameters best managing configuration changes , install updates on network drop outs may occur during session on or connected particular hosts, longer lived sessions may not beneficial. in particular advice on these areas in context use scenario ssh vs paramiko control persist, pipelining , timeout params accelerate or no? evaluating suitability number of specified forks run if workin...

the mysql contains tables 0 date time : '0000-00-00 00:00:00'. when using ssma migrate database mssql facing error cannot insert dbnull. understandable since neither mysql or mssql has field nullable. what not understand changed ssma's default projet setting replace constant zero-date not null columns. constant choose : 1900-01-01. is there other settings must set? the way found go inside mysql database, alter every table having default value 0 based datetime allow null. then, update every of these fields update 0 based value null. here, using ssma tool work since no more 0 based date time. far being perfect works.

when appropriate use unsigned variable on signed one? in for loop? i hear lot of opinions , wanted see if there resembling consensus. for (unsigned int = 0; < something.length(); i++) { var = something.at(i); // idea. } i know java doesn't have unsigned values, , must have been concious decision on sun microsystems ' part. i glad find a conversation on subject, hadn't given thought before. in summary, signed general choice - when you're dead sure numbers positive - if you're going arithmetic on variable (like in typical loop case). if you're going bitwise things masks, unsigned starts make more sense. or, if you're desperate positive range taking advantage of sign bit. personally, signed because don't trust myself stay consistent , avoid mixing 2 types (like article warns against).

say have gsl_matrix * a . want write function retrieves e.g. number of rows in matrix, without having access else besides object itself. example: int num_rows(gsl_matrix * a){ //some operation(s) on find number of rows in matrix //store number in int r return r; } what write me? from https://www.gnu.org/software/gsl/manual/html_node/matrices.html gsl_matrix defined as: typedef struct { size_t size1; size_t size2; size_t tda; double * data; gsl_block * block; int owner; } gsl_matrix; and the number of rows size1. range of valid row indices runs 0 size1-1. size2 number of columns. range of valid column indices runs 0 size2-1. physical row dimension tda, or trailing dimension, specifies size of row of matrix laid out in memory. so if want number of rows in a use: int num_rows(gsl_matrix * a){ int r = a->size1; return r; }
