df1 (below) event log. variable 1 consists of (non-unique) timestamps (posixct). variables 2:4 consist of attributes of events (factors). i've created df2 , df3 define time bins. df2 stores initial time , df3 end time each time bin. question how expand df1 variable names of df2 (which same df3) while filling in true or false each event, based on wether event belongs 1 of time bins of variable. in other words, if event belongs time bin (as defined df2 , df3) value true, otherwise false. each event in df1 needs checked against time bins (all pairs of elements of df2 , 3), 1 variable (of df2&3) @ time. due large number of variables , events, cannot interactively. learn how r way, avoiding explicit loops, , taking advantage of vectorization. data (small sampled datasets) df1 <- data.frame(time.stamp = c("2015-01-05 15:00:00", "2015-01-05 15:01:00", "2015-01-05 15:02:00", "2015-01-05 15:02:00", "2015-01-05 15:03:00"

so task i've been set make animation of lamp. there buttons added different actions such change colour of sphere etc. code: sphere class public class sphere extends jpanel { private boolean flashinglights = false; private int x = 168; private int y = 75; private color[] colors = new color[] {color.orange, color.light_gray }; private int colorindex = 0; public void paintcomponent(graphics g) { super.paintcomponent(g); graphics2d g2 = (graphics2d) g; graphics2d g3 = (graphics2d) g; if (!flashinglights) { rectangle box0 = new rectangle(x+16, y+50,14, 50); g3.setcolor(color.black); g3.draw(box0); g3.fill(box0); rectangle box1 = new rectangle(x+16, y+90,14, 50); g3.setcolor(color.white); g3.draw(box1); g3.fill(box1); rectangle box2 = new rectangle(x+16, y+130,14, 50); g3.setcolor(color.black); g3.draw(box2); g3.fill(box2); rectangle box3 = new rectangle

i came across strange bug in javamail store isconnected() function. using in android application reconnect store if connection dropped. if (!store.isconnected()) store.connect(host, username, password); but, when connection dropped, function returns true first time called, , false second time called. means above code not trigger store.connect if store not connected, code: if (!store.isconnected()) store.connect(host, username, password); else if (!store.isconnected()) store.connect(host, username, password); will reconnect store because of second call isconnected() function return false. i don't know if explained bug enought. know if known behavior or not. maybe, doing wrong. or, maybe there better way reconnect store if disconnected. thank in advance! edit: this code: logger.warning("start1"); if (!store.isconnected()) { logger.warning("start1 conn"); store.connect(host, username, password); logger.warning("end1 conn&quo

i have problem asp.net mvc 4 application. have partial view fallowing code: <li>@using (html.beginform("logoff", "account", formmethod.post, new { id = "logoutform", style = "display: inline;" })) { @html.antiforgerytoken() <a href="javascript:document.getelementbyid('logoutform').submit()">log out</a> } </li> and after click "log out" im redirected to: /account/login?returnurl=%f2account%f2logoff , going action: // // get: /account/login [allowanonymous] public actionresult login() { viewbag.title = logintitle; return view(); } but want handle in action: [httppost] [validateantiforgerytoken] public actionresult logoff() { session["user"] = null; return redirecttoaction("index", "index"); } can me? it looks not logged in during logging off.

for implementing colored lightning in exercise-engine need composite mode add. there no mention of mode (and many other commonly used subtract, average, burn, etc...) here: https://docs.oracle.com/javase/tutorial/2d/advanced/compositing.html i don't find experimenting. since pretty new java suppose doing wrong. could please point me in right direction? i prefer not doing in software (mainly because don't want loose hardware-acceleration, secondly because don't know how). you right, alphacomposite cannot blending modes typically found in image editors. there 2 java2d libraries provide extended composite implementations: jhlabs filters swingx or if using javafx, has them out of box don't worry performance, pretty fast.

in standard browser, loading new url reset javascript context. ie. global variables, compiled functions , events cleared, , browser start clean slate. in atom-shell however, calling mainwindow.loadurl load new html file, keep javascript context alive. , variables need deleted hang around. how can tell atom-shell wipe out whole javascript context on renderer side? check out browserwindow.reload() or webcontents.reload() . if on 'renderer' side, can use remote.getcurrentwindow().reload() https://github.com/atom/atom-shell/blob/master/docs/api/browser-window.md#browserwindowreload if want wipe 'javascript context' on browser side too, need dereference window , create new window.

ok have complex function built using data.frames , in trying speed i've turned data.table. i'm totally new i'm quite befuddled. anyhow i've made much simpler toy example of want do, cannot work out how translate data.table format. here example in data.frame form: rows <- 10 data1 <- data.frame( id =1:rows, = seq(0.2, 0.55, length.out = rows), b = seq(0.35, 0.7, length.out = rows), c = seq(0.4, 0.83, length.out = rows), d = seq(0.6, 0.87, length.out = rows), e = seq(0.7, 0.99, length.out = rows), f = seq(0.52, 0.90, length.out = rows) ) dt1 <- data.table(data1) #for later data2 <- data.frame( id =3:1, = rep(3, 3), d = rep(2, 3), f = rep(1, 3) ) m.names <- c("a", "d", "f") data1[match(data2$id, data1$id),m.n

i did revision on sorting algorithms. while revisioning, imagined code selects optimal of 2 available sorting algorithms sort array, according array's size. example, has choose between insertion sort , quicksort . it's known quicksort used extensively sort large arrays , achieves average case time, o(nlogn) , although worst-case time o(n^2) . on other hand, insertion sort isn't recursive, may consume less cpu time when sorts small-sized array. so, should nice threshold size aforementioned code in order choose efficient of algorithms? other performance factors, "how close" given sequence sorted permutation, aren't concerning me right now. from princeton university's quicksort page cutoff insertion sort. mergesort, pays switch insertion sort tiny arrays. optimum value of cutoff system-dependent, value between 5 , 15 work in situations. i prefer cut off size of 15. again system dependent , may or may not best in case.

i'm creating button in tableview header in section 1. i so: func tableview(tableview: uitableview, viewforheaderinsection section: int) -> uiview? { let header = uiview(frame: cgrectmake(0, 0, tableview.frame.size.width, 40)) header.backgroundcolor = uicolor.greencolor() if section == 1 { var button = uibutton() button.frame = cgrectmake(100, 100, 100, 50) button.backgroundcolor = uicolor.greencolor() button.settitle("button", forstate: uicontrolstate.normal) button.addtarget(self, action: "action:", forcontrolevents: uicontrolevents.touchupinside) header.addsubview(button) } return header } func action(sender: uibutton){ println("button pressed") } the button appears in section 1 (as should) if press on instead of printing message, nothing happens. my problem wasn't specifying button.frame correctly. since button outside frame, never c

i'm trying create basic installer , i'm having trouble shortcut. installer works fine, program refuses start shortcut gets created because missing "start in" box information, how go putting information in vbs? here have far, shortcut gets created , else fine, code works fine other .exe's , launches them fine, not 1 program: set mypath=%cd% set script="%temp%\%random%-%random%-%random%-%random%.vbs" echo set ows = wscript.createobject("wscript.shell") >> %script% echo slinkfile = "%userprofile%\desktop\shortcut.lnk" >> %script% echo set olink = ows.createshortcut(slinkfile) >> %script% echo olink.targetpath = "%mypath%/myexe.exe" >> %script% echo olink.save >> %script% cscript /nologo %script% del %script% edit: here finished working script if needs 1 create shortcuts: set mypath=%cd% set script="%temp%\%random%-%random%-%random%-%random%.vbs" echo set ows = wscript.create

i have simple question makes me confused. i have 2 strings, , want count how many different characters between two. strings sorted, equal length. not split strings. for example input: abc, bcd output: 2, because , d different characters input: abce, bccd output: 4, because a, c, d , e different. i know can in o(n^2), how can solve in o(n) these sorted strings? only need number of different characters, no need indicate number. i thinking needed complicated algorithm, smith-waterman example. restrictions on input makes easy implement in o(m + n) , m length of first string, , n length of second string. we can use builtin algorithm calculate number of characters in common, , can use information produce number looking for: #include <algorithm> #include <iostream> #include <string> int main() { std::string m = "abce"; std::string n = "bccd"; std::string result; std::set_intersection( m.begin
