css - What is the difference among col-lg-*, col-md-* and col-sm-* in Bootstrap? -

what difference among col-lg-* , col-md-* , col-sm-* in twitter bootstrap 3? the bootstrap 3 grid comes in 4 tiers (or "breakpoints")... extra small (for smartphones .col-xs-* ) small (for tablets .col-sm-* ) medium (for laptops .col-md-* ) large (for laptops/desktops .col-lg-* ). these grid sizes enable control grid behavior on different widths. different tiers controlled css media queries . so in bootstrap's 12-column grid... col-sm-3 3 of 12 columns wide (25%) on typical small device width (> 768 pixels) col-md-3 3 of 12 columns wide (25%) on typical medium device width (> 992 pixels) the smallest tier set ( xs , sm or md ) defines size larger screen widths. so, same size column on tiers, set width smallest viewport... <div class="col-lg-3 col-md-3 col-sm-3">..</div> same as, <div class="col-sm-3">..</div> because col-sm-3 means 3 units on sm , up , unless overridden larg

i know go-to rule use shared_ptr s or other smart pointers. however, i'm not sure how implement without copy ctor'ing std::make_shared . i'll elaborate: the problem i want create tree-like expression, like: struct foo{ std::vector<foo*> v; }; this allows me following: foo add(foo& f1, foo& f2){ return foo {&f1, &f2}; } that's good, because 2 become children of new node. i want following evaluated correctly: foo x, y; auto z = add(x,y); assert(z.v[0] == &x && z.v[1] == &y); this way, there's no copying , it's good. however, have resource management issue here. addressing resource management issue if these elements allocated on heap, , unknowingly might, we'll run memory leak. best way use smart pointers raii: struct foo{ std::vector<std::shared_ptr<foo> > v; }; foo add(foo& f1, foo& f2){ return foo {std::make_shared<foo>(f1), std::make_shared<foo>

sql server - RSQLServer: Cannot begin a nested transaction after dbRollback -

background in database have uniqueness constraints. if data breaks 1 of conditions, error message violation of unique key constraint . i use trycatch in code, capture error , return meaningful message user. far good. however, if try run new transaction on server after having captured error, error message saying cannot begin nested transaction. my findings i traced error down, , figured when dbrollback called (either explicitly, or within withtransaction ) 1 cannot submit new dbbegin anymore (either explicitly or implicitly via dbwritetable , friends). what need unstuck, run dbcommit , allowed run dbbegin . looking @ code of dbcommit , dbrollback see in former case setautocommit set true, signals dbbegin not nesting transactions. not case dbrollback : getmethod("dbcommit", "sqlserverconnection") # method definition: # # function (conn, ...) # { # rjava::.jcall(conn@jc, "v", "commit") # rjava::.jcall(conn@jc,
