in laravel 4.2 have route defined this: route::get('author/{id}/edit', ...); when tried redirect link random id previous 1 failed: return redirect::to('author/{id}'); // or return redirect::to('author/(:any)'); but works when use redirect id manually like: return redirect::to('author/8'); // or return redirect::to('author/9'); how redirect random id or how use redirect parameters? best practice use named routes, way can point named route. when url changes, application still work based on name of route. in case, use: route::get('author/{id}/edit', ['as' => 'author.edit', 'uses' => 'authorcontroller@edit']); this way name of route 'author.edit'. when try redirect route, can use redirect::route('author.edit', $authorid); i tested this, , works random id, example: return redirect::route('author.edit', rand());

how can forced child class implement protocol declared in parent class? i tried this: protocol myprotocol { var myvar : string { } } class parentclass: myprotocol { var myvar = "parent" } class childclass: parentclass { } but child class doesn't force me override myvar. this possible ? thank much, morgan as far knowledge not possible in swift. if try conforming parent class's protocol, leads error "cannot override stored property". since protocol conformed in parentclass. protocol myprotocol { var myvar : string { } } class parentclass: myprotocol { var myvar = "parent" } class childclass: parentclass { var myvar = "hello" // throws compilation error, "cannot override stored property" since it's conformed parentclass itself. } added: in general words multi-level implementation of interface not possible, in ios words protocol's should implemented @ single level

in sailsjs, validate request parameters using same mechanism when models validated when model actions performed. so when define model use "attributes" option specify parameter properties, , used validation. but if you'd validate login form or email form on server side, there no model needed , you'd validate parameters? so i'd able this: //login validation req.validate({ email: { required: true, email: true }, password: { required: true } }); //send email validation req.validate({ subject: { required: true, type: 'string' }, to: { required: true, type: 'string' }, body: { required: true, type: 'string' } }); a function req.validate mixed in requests , called if req.options.usage set request, i've played bit don't quite understand it's doing. there no documentation on nor in "anchor" what's used validation. any or suggestions on how achieve (preferably undocumented sailsjs feature)?

i've been reading few methods fit circle data (like this ). see how methods work on real data , thought of using r this. tried searching rseek packages can came nothing useful. so, there packages compute best fit circle given data set (similar how lm() fit linear model data set)? otherwise, how might 1 perform such task in r? here's naive implementation of function minimises ss(a,b,r) paper: fitss <- function(xy, a0=mean(xy[,1]), b0=mean(xy[,2]), r0 = mean(sqrt((xy[,1]-a0)^2 + (xy[,2]-b0)^2)), ...){ ss <- function(abr){ sum((abr[3] - sqrt((xy[,1]-abr[1])^2 + (xy[,2]-abr[2])^2))^2) } optim(c(a0,b0,r0), ss, ...) } i've written couple of supporting functions generate random data on circles , plot circles. hence: > xy = sim_circles(10) > f = fitss(xy) > plot(xy,asp=1,xlim=c(-2,2),ylim=c(-2,2)) > lines(circlexy(f$par)) note doesn't use gradi

lets want train cascade recognize 1 object, object has different shapes. example if want recognize cup. know there cups in many shapes have similarities. or example: steering wheel. can tell object steering wheel has different shapes. question: can train cascade recognize of different shapes of 1 object? if train 1 cascade many false positives due high variance of positive samples. however if have, 20 stable classifiers, focused on different shapes, can or , use them. suggestions on steering wheel case do not use steered wheels positives, use 0 - degree wheels, make classifier converge onto something. group wheels similarity in shape (color not important boosted cascade , background not important because cars have similar gauge displays) , train cascades on these groups search wheel in rotations - note symmetries - since boosted cascade rotation invariant - , steering wheel steered.

i'm creating app has 15 (!) flavors. app works google play services, need register client id application. every flavor has own applicationid (package name) , google developers console needs package name certificate sha1 fingerprint. flavors use single keystore. should register 15 different android apps on google developers console? possible single client id different flavors? package name identifies app, 15 different packages means 15 apks. 1 project work on has on 20 , works fine.

i have problem 1 steps have do. important problem. have image, example: the second step's select part of image: ok. if have image in cache, selected area: early steps have done. problem last step, task select (exactly outer) border area. here's example how should looks: my ask's algorithm or steps have last effect. it's feasible images? prefered language's c#/c/js if know knowledge solution nice! had find algorithm detect edge, not outer edge. maybe try following: pick random 10 pixels borders of selection (it important borders) get average rgb of pixels get max = max color distance between pixels perform white flood fill tolerance = k*max, starting 1 of edge pixels this way should able flood fill gray background in selection

i want use xml-file dataset save changes. datatable.readxml("c:\test.xml") works fine. want use xml resource file. tried dim xmldoc string xmldoc = myapplication.my.resources.xmltestfile datatable.readxml(xmldoc) gives me error illigal sign in path , debugging shows me xmldoc empty. could me working? readxml requires filename not content use dim ds new dataset() using stringreader new stringreader(.......resource.here.......) ds = new dataset() ds.readxml(stringreader) end using dim dt datatable = ds.tables(0)

when make new project. say, web app using snap. generate skeleton using snap init barebones , make new sandbox , install dependencies. this takes forever. seriously. if have ever worked pretty other web framework (node.js express, example), process identical takes fraction of time. i'm aware node dependencies not require compilation find strange isn't considered bigger problem. example, never able run yesod app on cheap vps because vps isn't powerful enough compile , can't upload 500mb of precompiled libraries. the question is, why doesn't repository host binaries instead of code? .net compiled (to bytecode) can use it's dlls without need recompilation. there of course drawbacks of hosting binaries more storage space needed, multiple binaries per library multiple oss... problems seems insignificant huge benefits such as no more compile errors much faster setup new projects significantly less memory needed knowing library doesn't support os b

i doing program changes number in base 10 base 7, did : num = int(raw_input("")) mod = int(0) list = [] while num> 0: mod = num%7 num = num/7 list.append(mod) list.reverse() in range (0,len(list)): print list[i], but if number 210 prints 4 2 0 how rid of spaces you can use join list comprehension: >>> l=range(5) >>> print l [0, 1, 2, 3, 4] >>> ''.join(str(i) in l) '01234' also, don't use list variable name since built-in function.
