suppose have 1x10 struct my_struct 2 fields: fielda , fieldb . how should assign scalar number (or other entity) on specific position fields in more direct form? in other words, there way this: my_struct(5).fielda = pi; my_struct(5).fieldb = pi; in way this: my_struct(5).* = pi or my_struct(5) = deal(pi) ? you can use combination of fieldnames , cell2struct programmatically build struct same value in fields, , full-struct assignment. function out = setallfields(s, value) %setallfields build scalar struct template, replacing field values % s template struct, , value value desired in fields out = cell2struct(repmat({value}, [numel(fieldnames(s)) 1]), fieldnames(s)); with function defined, can assignment this, using single or multiple target indexes. my_struct(5) = setallfields(my_struct, pi); my_struct([2 4:6]) = setallfields(my_struct, 'foo');

according documentation , strings longer specified character varying or varchar should truncated: if 1 explicitly casts value character varying(n) or character(n), over-length value truncated n characters without raising error. (this required sql standard.) but can not work. documentation 1 has "explicitly" cast value character varying maybe missing that. below simple test table: create table test1( tval character varying(20)); where following fails error: value long type character varying(20) insert test1 values ('this super long string want see if truncated'); how can work? this won't truncate, because it's assignment: create table test1(tval character varying(20)); insert test1 values ('this super long string want see if truncated'); but will, because it's explicit cast : insert test1 values (cast('this super long string want see if truncated' varchar(20))); to truncation behaviour must use explici

is possible have 1 core dll written in mono , 3 separated native uis on linux, mac , windows? if yes, options have? let's assume have written gui wpf (windows) , want connect mono dll wpf form can use it's exported functions , classes. same on mac os x: gui written in cocoa , connected mono core dll? do guys know example projects, uses approach? well, can use pcl library contains logic, combined xamarin.mac framework on osx, gtksharp on linux, , wpf on windows. using raw cocoa, that'd tougher; you'd have host mono runtime (which not impossible not easy). edit: should add could try "write once" ui , use gtksharp three.

in go database/sql package says rare close database db.close because meant shared many go routines. 1 better when given 100 functions queries same data: open database inside each function open database 1 time , use same connection every 100 function. 1 easier because if 1 fails other 99 can still working. , no need pass database connection arguments. in performance wise 1 better? you missed important part of documentation says: the returned db safe concurrent use multiple goroutines , maintains own pool of idle connections . thus, open function should called once. necessary close db. (emphasis mine) so, option #2 doesn't make sense. connections pooled - use same connection every 100 function doesn't apply. also, option #1 waste of time - once documentation states, call ping after make sure fine (and have attempt connect database - regardless of driver).
