i've found objective-c socketio library , trying implement in first swift app. here's code i'm trying port: __weak typeof(self) weakself = self; self.socket.onconnect = ^() { weakself.socketisconnected = yes; [weakself mapview: weakself.mapview didupdateuserlocation: weakself.mapview.userlocation]; }; from limited understanding ^() {} block in objective c. i've looked , closures seem loose equivalent swift . first obvious question how same result in swift? i've tried following error fatal error: unexpectedly found nil while unwrapping optional value (lldb) : self.socket.onconnect = { () -> void in println("connected!") } also, behind scenes what's happening here? asynchronous callback function seem appropriate wasn't used , i'd understand why. update as pointed out @jtbandes, socket in fact nil code running outside of connection callback (i know, silly mistake). solution first question: siosocket.socketwith

i have got nodejs app imap "append" new message gmail, custom date/time. works fine. but, how make gmail treat actual new incoming email? (which needs sorted based on existing filters, pushed spam if needed,etc). functions carried out on new incoming email gmail. there such event can raised on newly created email, maybe using uid? gmail support such functionality through imap? p.s: using "inbox" npm package. tried reading imap spec, couldn't understand much. (only got understand append command part). no. imap append means 'put directly in folder'. can use flags argument of append make sure don't mark \seen, it'll unread message. the way make new email steps , filtering send via smtp.

string = "abc3jfd456" suppose have above string, , wish find first digit in string , store value. in case, want store value 3 (since it's first-occuring digit in string). grepl("\\d", string) returns logical value, not tell me or first digit is. regular expression should use find value of first digit? base r regmatches(string, regexpr("\\d", string)) ## [1] "3" or using stringi library(stringi) stri_extract_first(string, regex = "\\d") ## [1] "3" or using stringr library(stringr) str_extract(string, "\\d") ## [1] "3"

i received design (photoshop) layout designer in pixels. how convert points required ios? i tried substituting pixles points thinking may 1:1 conversion on coding in app design looks weird (bigger expected). table header height example: tried converted 32px+40px of psd = 72 points in ios in comps table header little bigger navbar (which ofcourse 44 points). should designer providing layout in points rather pixels? if not how convert pixels points ios? converting pixels points depends on target ios device. on 1x device (ipad 1 & 2, iphone 3gs), 1 uikit point == 1 pixel. on retina devices (ipad 3 , up, iphone 4 , up), 1 uikit point == 2 pixels.

i having trouble doing simple, painting array of elements. here have paint method in class array: ( xb , yb x , y values want increment make instances show in different locations). public void paint(graphics pane) { private box[] boxes = new box[num_box]; for(int = 0; i<num_box; i++){ if (xb == 290){ xb = 0; yb = yb + 20; } boxes[i].paint(pane, xb, yb); xb = xb + 20; } and here have in box class being painted: public class box { private final int width = 20; private final int height = 20; private boolean = true; public void paint(graphics pane, int x, int y) { pane.setcolor(color.black); pane.drawrect(x, y, width, height); pane.setcolor(color.gray); pane.fill3drect(x +2, y+2, width - 3, height - 3, up); } } every time run it, tells me there nullpointerexception @ boxes[i].paint(pane,xb,yb) line. doing wrong?

assuming straight line pointing north 0 degrees , goes 359. if given 2 points each x , y value, how find out "angle" makes between first point , second point? assuming (arctan2) function exists okay. i have following: var x = x2 - x1; var y = y2 - y1; var radian = arctan2(y, x); var degrees = radian * 180 / 3.14; i seem getting "0 degrees" on right arrow , 270 pointing north instead of 0 degrees looking towards north. if coordinate system have 0 degrees pointing up/north x comes first atan2 function: var x = x2 - x1; var y = y2 - y1; var angledegrees = math.atan2(x, y) * 180 / math.pi; if (angledegrees < 0) angledegrees += 360; // force positive value

i want join named scopes generate them array. how wouldi , can't join named scopes, there better way this? scope :search, ->(attrs_for_search,params) if attrs_for_search.present? params_to_search_on = params.keys & attrs_for_search params_to_search_on.collect{|x| where("#{x} ilike ?", "%#{params[x]}%") } else none end end contact.search(%w[email],{'email => 'jason'}) i think can create scope , use 'send' method join scopes. scope :search, ->(field, value) where("#{field} ?", "%#{value}%") end def self.multi_search(params) result = nil params_to_search_on = params.keys params_to_search_on.each |k| if result.nil? result = message.send(:search, k, params[k]) else result = result.send(:search, k, params[k]) end end result end hopes you.

can convert symbol product of products array of products? i tried this: syms b c d; d = a*b*c; factor(d); but doesn't factor out (mostly because isn't factor designed do). ans = a*b*c i need work if b or c replaced arbitrarily complicated parenthesized function, , nice without knowing variables in function. for example (all variables symbolic): d = x*(x-1)*(cos(z) + n); factoring_function(d); should be: [x, x-1, (cos(z) + n)] it seems string parsing problem, i'm not confident can convert symbolic variables afterwards (also, string parsing in matlab sounds tedious). thank you! use regexp on string split based on * : >> str = 'x*(x-1)*(cos(z) + n)'; >> factors_str = regexp(str, '\*', 'split') factors_str = 'x' '(x-1)' '(cos(z) + n)' the result factor_str cell array of strings. convert cell array of sym objects, use n = numel(factors_str); factors = cell(1,n); %//

i used function imwrite of opencv python in order convert set of images png jpeg format, without specifying quality (the default value 95), obtained first set of jpeg images . then used same function in order convert same set of images png jpeg format, specifying value 75 quality, obtained second set of jpeg images . finally, tried use same function in order convert first set of jpeg images, specifying value 75 quality, obtained third set of jpeg images . when perform binary comparison between second , third set of jpeg images, images different. why? target quality same (75), source images different. when first compression (quality 95) first set of jpegs not going identical input pngs when uncompressed. jpeg lossy. means input quality 75 compression not same. in first case original png images, , in second case jpeg distorted version of same files. since input images not same, output not same either.

in simplified scenario, have script looks this: mv test _test sleep 10 echo $1 mv _test test and if execute with: ssh localhost "test.sh foo" the test file have underscore in name long script running, , when script finished, send foo back. script should keep running, if terminate ssh command pressing ctrl+c or if lose connection the server, doesn't (the file not renamed "test"). so, tried following: nohup ssh localhost "test.sh foo" and makes ssh immune ctrl+c flaky connection server still causes trouble. after debugging, turns out script reach end if there no echo in it. , when think it, makes sense - when connection dropped, there no more stdout (ssh socket) echo to, fail, silently. i can, of course, echo file , file, prefer smarter, along lines of test tty && echo $1 (but tty invoked returns false ). suggestions appreciated. the following command want: ssh -t user@host 'nohup ~/test.sh foo > nohup.o

in model class, have simple getter function so: def geoloc = { geoquant match { case "country" => country.find.byid(geolocid) case "provice" => province.find.byid(geolocid.tolong) case "city" => city.find.byid(geolocid.tolong) case "street" => street.find.byid(geolocid.tolong) } } the idea being geolocation of object – can of either of 4 types. see, function geoloc has return type super class of all: country , province , city & street – extend model class. instead function's return type model geoentity , geoentity trait each of these classes have along model . why happen? can make function return specific types pattern matching? scala infers specific type can. each of 4 instances both model , geoentity , that's inferred type: model geoentity . if want function return less specific type of model (all model geoentity s model s, not models model geoentity s), a
