this question has nice solution of flattening lists while preserving data types (which unlist not): flatten = function(x, unlist.vectors=f) { while(any(vapply(x, is.list, logical(1)))) { if (! unlist.vectors) x = lapply(x, function(x) if(is.list(x)) x else list(x)) x = unlist(x, recursive=f) } x } if give following list, behaves expected: > = list(c(1,2,3), list(52, 561), "a") > flatten(a) [[1]] [1] 1 2 3 [[2]] [1] 52 [[3]] [1] 561 [[4]] [1] "a" now i'd restructure flat list a . relist fails miserably: > relist(flatten(a), skeleton=a) [[1]] [[1]][[1]] [1] 1 2 3 [[1]][[2]] [1] 52 [[1]][[3]] [1] 561 [[2]] [[2]][[1]] [[2]][[1]][[1]] [1] "a" [[2]][[2]] [[2]][[2]][[1]] null [[3]] [[3]][[1]] null now, of course relist(unlist(b), a) loses data types again. way restructure flat list? bonus points if handles analogous attribute unlist.vectors correctly. one way is: relist...

i use phonegap-nfc plugin chariotsolutions. reading nfc tag while app running no problem. registered app intents starts when app in background , tag read. ndeflistener not fired. know how tag information when app started intent? you need add mime type listener nfcevent fired intent when application launches. you can use same event handler using ndef listener, same except event type. don't need specify mime type. nfc.addmimetypelistener("", app.onnfc, success, failure); this bit odd, way works because of how events fired in plugin implementation.

using vim-snipmate have following problem: if try expand snippet within snippet, snipmate takes me next placeholder of current snippet instead of expanding new snippet. e.g.: if press tab in following situation: for (i = 0; < 10; i++) { ifi<press tab here> } i expect: for (i = 0; < 10; i++) { if (<cursor position>) ; } but following: for (i = 0; < 10; i++) { ifi }<cursor position> is there way expand snippets within snippets or @ least way suppress going next placeholder? best regards the original snipmate did not support recursive snippet expansion. apparently, fork doesn't, neither. wouldn't hurt ask on project's issue tracker such support. a modern alternative (that requires python though) ultisnips . far know, 1 support snippets within snippets.

i have application uses many nogil cdef function , profile them in order find bottle-necks. i tried passing profile=true directive cython these functions seem imune, such output of cprofile.run() contains timings of functions calling cdef functions, not of cdef functions themselves. is there directive or profiler can used in order profile cdef functions? edit: this link application file referring to... . in order profile must set: #cython: profile=true at header. the profiler needs gil , so, of comments @veedrac, solution to: use cdef functions without nogil directive set #cython: profile=true @ header of .pyx ( or somewhere else ) the drawback here that, removing nogil , 1 can not use prange in order profile parallel execution. question remains... possible profile nogil function?

i have following problem: i delete subdirectories , files recursively. have follow: 200 subdirectories. each of them has structure: case a0 a1 a2---------a100 each folder of 100 has 3 sub-folders. 2 of them should kept. other 1 has subdir , multiple files. want keep 1 of files , want keep subfolder i hope picture show want do. have folder let's case. folder has 100 subdirectories. example 0 folder, want keep b , d. in folder c want keep k , file l.gz. process should run 100 folders a0-a100. thank help. apreciate if 1 on that.

i'm been ask jacobian in matlab solve coordinates highest value f(x) , max value same function. the function have work : f(x; y) = (x^3y + 5x^2y^2)/ e^(x^2+3y^4) so have accomplished far: function [j1,j2]=j(x) [3*x(1)^2+20*x(1)*x(2)-36*x(1)^2*x(2)^4-120*x(1)*x(2)^5,10*x(1)^2-48*x(1)^3*x(2)^3-300*x(1)^2*x(2)^4;6*x(1)*x(2)+10*x(2)^2-8*x(1)^3*x(2)-30*x(1)^2*x(2)^2,3*x(1)^2+20*x(1)*x(2)-2*x(1)^4-20*x(1)^3*x(2)] end i believe matrix including 4 derivatives of f(x) . nut don't know how solve 2 questions. the answer given in comments, make sure question not remain unanswerd post here: first wrote jocobian matris function = j(x) j11 = 6*x(1)*x(2)+10*x(2)^2-8*x(1)^3*x(2)-30*x(1)^2*x(2)^2; j12 = 3*x(1)^2+20*x(1)*x(2)-2*x(1)^4-20*x(1)^3*x(2); j21 = 3*x(1)^2+20*x(1)*x(2)-36*x(1)^2*x(2)^4-120*x(1)*x(2)^5; j22 = 10*x(1)^2-48*x(1)^3*x(2)^3-300*x(1)^2*x(2)^4; = [j11, j12;j21, j22]; end then used function estimate criticalpoints function xnp1 = new...
