in vala see when declare array have specify type, like int[] myarray = { 1, 2, 3 }; i wonder if there way have mixed array like smtg[] myarray = { 1, 'two', 3 }; i see in this question in c++ , c# it's not possible started learning vala , have no background c -like language want sure. no. that said, can create array of can hold other types, glib.value or glib.variant , , vala can automatically convert to/from two, like glib.value[] values = { 1, "two", 3.0 } it's terrible idea (you're throwing away compile time type safety), can it.

my website created using drupal 7 on 1 instance of amazon & database on amazon rds . whenever taking backup of database using mysql root user & simultaneously when developer try clear cache on website time website goes offline untill backup gets on around 30 min happens everytime . solution avoid problem. try use parameter when taking backup mysqldump . --lock-tables myisam storage engine. --single-transaction innodb storage engine. --lock-tables lock tables before dumping them. tables locked read local allow concurrent inserts in case of myisam tables. for transactional tables such innodb , bdb, --single-transaction better option, because not need lock tables @ all .--single-transaction produces checkpoint allows dump capture data prior checkpoint while receiving incoming changes. incoming changes not become part of dump. ensures same point-in-time tables.

i trying diagnose memory leak (or thought memory leak) in real time audio program, causes output "stutter" when garbage collection routine called. in attempt basics , elaborate successively until found leak, devised thought simplest possible , leak-free program: public class leakdetect { public static void main(string args[]) { while (true) { system.out.println( runtime.getruntime().freememory()); } } } imagine surprise find heap space decreases on time (easily visible on course of seconds) , jumps again, though there no action here other printing available heap memory. i have never had cause wonder this; going on here? does java/eclipse forcibly reserve chunk of memory heap, , subsequently wasteful behind scenes? or, suspect, other programs , os functions (windows 10) eating potential heap space available, , os freeing memory? if so, there way make java/eclipse take harder line keeping os , other software out of space? r...

as beginner in c experimenting something, excluded standard library <stdio.h> , still there no error. can explain it? here sample code: main() { printf("hello, world!\n"); } this program working same or without library. why? tl;dr -- you're excluding header file, not standard library. if exclude header file function having forward declaration, you'll receive warning sure mentioning "implicit declaration" of function. in case, (invalid per latest standards), function assumed return int , no check on number of parameters passed there. however, default, generated object file source linked default c library libc has function definition present. in case, function return type matches implicit case, linker happily links object files together. so, finishes linking , works same . that said, main() should int main(void) , @ least conform standards.

does know how use gcc generate possible binary files object files ? know can use : "gcc -mm" generate .o files given source files. but how use gcc generate possible binary files object files in project ? example: use "gcc -mm" generate: a.o, b.o, c.o, d.o if 1 trying generate list of binaries files built each of .o files this: a: b.o c.o d.o b: a.o c.o d.o c: a.o b.o d.o d: a.o b.o b.o i can perl script, curious if there way gcc thanks short answer, "no, but..." gcc -mm can give foo.o: bar.h because foo.cc contains directive: #include "bar.h" that's easy. foo.cc can contain declaration: int bar_f1(int); how can gcc know object file contains binary code function? or if there two object files containing functions signature, should use? can't. ...unless... long answer, "yes, if..." if refrain giving source files forward declarations of things in other source files, , refrain giving head...

if have std::vector want overwrite (not resize). safest way in terms of memory management? example int main() { std::vector<float> x (5, 5.0); x = std::vector<float> (6, 6.0); x = std::vector<float> (4, 4.0); } will create vector of 5 floats of value 5.0. overwrite vector of size 6 values 6.0, overwrite vector of size 4 values 4.0. if i'm performing type of operation indefinite number of times, there risks of corrupting or leaking memory approach? should using clear() before each overwrite? there more efficient way achieve this? i'm sure question has been asked many times google isn't pulling exact scenario looking for. thanks! std::vector has specific member functions doing this. allocators , copy/move aside, each of vector 's constructors has corresponding overload of assign same thing. if want reuse vector 's storage, use it: std::vector<float> x (5, 5.0); x.assign(6, 6.0); x.assign(4, 4.0); of cour...
