in process of familiarizing myself go , goroutines have hit road block executing commands. format of these commands are: sudo find /folder -type f | while read i; sudo -s chmod 644 "$i"; done with code taken how execute system command in golang unknown arguments i'm trying execute command believe it's not executing due first argument being sudo, wrong. have 2 questions. when these commands fail run returned "exit status 1", there way more detailed error doing? question two, why getting "exit status 1" script? going on isn't supposed to? package main import ( "bufio" "fmt" "os" "os/exec" "strings" "sync" ) func execmd(cmd string, wg *sync.waitgroup) { parts := strings.fields(cmd) head := parts[0] // head @ point "sudo" parts = parts[1:len(parts)] out, err := exec.command(head,parts...).output() if err != nil { ...

i'm wondering efficient way value of first column in datagridview row. currently, i'm using code: list<string> selectedrows = new list<string>(); foreach (datagridviewrow r in dgv.selectedrows) { selectedrows.add(r.cells[0].value.tostring()); } int index = convert.toint32(selectedrows[0]); this works fine; however, there more efficient option this? "most efficient" subjective. don't know following code faster or shorter you've got, it's method prefer use. if you're trying list of values particular column, try this: var results = datagridview1.selectedrows .cast<datagridviewrow>() .select(x => convert.tostring(x.cells[0].value)); if allow 1 selected row @ time, , want convert particular cell, try this: var index = convert.toint32(datagridview1.currentrow.cells[0].value);

i need trigger check if updated worker can moved other team create table workers ( id_worker number(4,0), --fk id_team number(2,0) --fk ); my trigger looks like: create or replace trigger team_limit before insert or update of id_team on workers each row declare v_num number; begin select count(*) v_num worker id_team=:new.id_team; if v_num >= 5 raise_application_error(-20025,' error nr ... bleble'); end if; end; this generate error : "table %s.%s mutating, trigger/function may not see it" when row updated. how write statements not generate kind of error? you can use compound trigger, looks (not tested): create or replace trigger team_limit insert or update of id_team on workers compound trigger v_num number; type row_tabletype table of workers.id_team%type; affectedteams row_tabletype; before statement begin affectedteams := row_tabletype(); -- init table variable end before statement; -----------------...

pyspark supports common reductions sum , min , count , ... support boolean reductions all , any ? i can fold on or_ , and_ seems inefficient. no underlying scala api doesn't have python 1 won't. don't think add either it's easy define in terms of filter . yes using fold inefficient because won't parallelelize. .filter(!condition).take(1).isempty mean .forall(condition) , .filter(condition).take(1).nonempty mean .exists(condition) (general suggestion: underlying scala api more flexible python api, suggest move - makes debugging easier have less layers dig through. scala means scalable language - it's better scalable applications , more robust dynamically typed languages)

hi trying parse vml path value using java string manipulation. want retreive commands in path moveto , lineto , curveto , rlineto (other commands) , corresponding x , y coordinates/parameters. here example data parse, each command has own x,y coordinates. 1. m1,1 l1,200,200,200,200,1 xe 2. m, l1,200,200,200,200,1 xe can suggest algorithm or code on retreiving commands , parameters each command? example in number 1. command = moveto 'm' command parameters = (x=1,y=1). ref: http://www.w3.org/tr/note-vml#_toc416858391 this weird tried using stringtokenizer stringtokenizer tokenizer = new stringtokenizer(path); a friend suggested using stringtokenizer , did near goal, gave me following data. maybe can utilize stringtokenizer suit needs. m1,1 l1,200,200,200,200,1 xe for #1, here ideal output.
