i'm new string manipulations in r. have case in i'm using several matched replacements in foor loop, , has rely on gsub. now have string (illustrative example), "today great day" in want use pattern "today is" only, , replace "my value" but metacharacters need select rest of string? my try gsub("today is+.", "my value", myobject) now selects 1 value after "today is", how can make run way? use capture-class grouping parens in pattern, , refer them \\<n> in replacement, , think need swap order of .+ in pattern: > gsub("(today is)(.+)", "my value\\2", "today great day") [1] "my value great day"

using wireshark display packet information, name resolved source , destination port -> 1 0.000000 121.14.142.72 0.32.59.21 tcp 62 ms-wbt-server 48983 where last 2 values-> ms-wbt-server , 48983 source port , destination ports. instead want see port number , not name resolution. does know if setting possible in wireshark? there 2 ways of doing that. the first turn off transport-layer name resolution. that's view -> name resolution -> enable transport layer in gtk+ version , view -> name resolution -> resolve transport layer in qt version; if it's checked, select it, disable (and un-check) it. prevent port numbers being resolved names everywhere in wireshark. the second use "src port (unresolved)" , "dst port (unresolved)" rather "source port" , "destination port" port number column. affect column display, you're showing in example above.

if put endless loop in javafx-launcher thread , application never start. know runs on different thread , why happen? just create new project , override init() , add forever loop. // mine not forever boolean go = true; @override public void init() throws exception { // todo auto-generated method stub super.init(); // 'while' comes after line while(go){} // comment guy , ayt } @override public void stop() throws exception { // todo auto-generated method stub go = false; super.stop(); } does mean javafx-launcher thread should exit before application ui can start -(i.e javafxapplication thread), or missing something? if javafx-launcher should alternative launching application needs before app starts, why can't concurrent, because if want in successions place code before super.init() method? direct explanation of happening the documentation application start method explicitly states happening: the start method called

we trying deploy code using jenkins our qa , our maven goals include -p analysis in used find check style errors. now, problem got lot of check style errors , need push code qa immediately. can build jenkins removing -p analysis in goals ignores check style errors? can ignore check style errors , push code? cause problems in future? please suggest me correct method. thanks! this team , internal culture. using automated tool enforce consistent style can avoid style debates during code reviews , can prevent developers reformating files liking. (here's question discussing other benefits of maintaining consistent style: research advantages of having standard coding style ) you can disable check push code now, long term want fix errors (whether style definition or code) , keep checks on. behoove ensure when developers build locally same errors code doesn't checked in fail check.

i implementing multibit trie in c. getting segmentation fault error. when run program. don't know going wrong? the node of multi bit trie that: struct mtnode{ /* nodes array 8 elements. each element pointer child node.*/ mtnode* nodes[8]; // 2^stride = 2^3 = 8 int nexthop; }; each node initialized following: typedef mtnode node; node *init_mtnode(){ node *ret = (node*) malloc(sizeof(node)); int size = (int)pow(2,stride); (int i=0; i<size ; ++i) { ret->nodes[i] = null; } ret->nexthop = -1; return ret; } is wrong in init_mtnode method? there multiple possible reasons: you don't check malloc() null , unlike new throw exception, malloc() return null if error happens. you calculate value of size , loop size times, array can hold 8 pointers. try this typedef mtnode node; node *init_mtnode() { node *ret; int size; ret = static_cast<node *>(mall
