i trying add 2 authentication controllers 1 route. example, trying make: router.route('/employees') .get(authcontroller1.isauthenticated, mycontroller1.get1) .get(authcontroller2.isauthenticated, mycontroller2.get2); the isauthenticated function follows: exports.isauthenticated = passport.authenticate('basic', { session: false }); does know how possible? thanks, daniel route: router.route('/employees') .get(authcontroller.isauthenticated1, authcontroller.isauthenticated2, mycontroller1.get1) authcontroller : exports.isauthenticated = function(req, res, next) { // authentication code if (!req.isauthenticated) { // not authenticated return res.status(401).send({ message: 'user not authenticated' }); } next(); }; exports.isauthenticated2 = function(req, res, next) { // authentication2 code if (!req.isauthenticated2) { // not authenticated

if multiplying 3 matrices together, abc. depending on size of matrices may more efficient perform either (ab)c or a(bc). if evaluate: a %*% b %*% c will optimised in anyway? thanks colonel beauvel setting me on right path - test it. using example wikipedia , scaling suitably: > mult <- 100 > ar <- 10 * mult > ac <- 30 * mult > br <- 30 * mult > bc <- 5 * mult > cr <- 5 * mult > cc <- 60 * mult > > <- matrix(rnorm(ar * ac), ar, ac) > b <- matrix(rnorm(br * bc), br, bc) > c <- matrix(rnorm(cr * cc), cr, cc) > > system.time({ (a %*% b) %*% c }) user system elapsed 3.01 0.00 3.01 > system.time({ %*% (b %*% c) }) user system elapsed 25.34 0.03 25.37 > system.time({ %*% b %*% c }) user system elapsed 2.98 0.00 2.98 > system.time({ t(c) %*% t(b) %*% t(a) }) user system elapsed 25.61 0.03 25.64 incidently - r evaluates left righ

when creating wpf window allowstransparency="true" windowstyle="none" , maximizing via this.windowstate = windowstate.maximized; window gets bigger screen. when setting allowtransparency="false" have border around window, window won't bigger screen. in case have 1920x1080 screen , window becomes 1934x1094. on 1280x1024 screen window become 1294x1038. window become still big this, whether or not allowtransparency enabled or not, yet disabled works properly. setting allowtransparency before maximizing doesen't work , throws invalidoperationexception. how wpf window without windows-style border, yet maximize properly? it seems pretty common issue. appears you'll have bind height , width actual height/width of screen stated in stackoverflow post: borderless window application takes more space screen resolution . i hope solves issue you're facing.

i'm new python please excuse if i've glazed on simple this. i have object this: class myobject(object): def __init__(self): self.attr1 = none self.attr2 = none @property def prop1(self): return foo.some_func(self.attr1) and instantiate this: a = myobject() a.attr1 = 'apple' a.attr2 = 'banana' and method it's wrapped in expects return of dict, this: return a.__dict__ but prop1 not included in return. understand why is, it's not in object's __dict__ because holds real attributes. so question is, how can make return, return this: {'attr1': 'apple', 'attr2': 'banana', 'prop1': 'modifiedapple'} other right before return doing: a.prop1_1 = a.prop1 you should leave __dict__ be, use attributes live directly on instance. if need produce dictionary attribute names , values includes property, add property or method produces new dicitonary

i thinking writing session handler (using session_set_save_handler) stores each session variable in it's own file. maybe have session_id directory, , each variable stored in own file, session key filename. my purpose is: non-blocking (or lesser-blocking) session. i.e. when run script opens session, don't have close session before script can write session. thinking session handler can open , close single file write access (read access ok because can close session , still access values using $_session). write given session variable, script won't need lock entire session. the application quite database heavy (it's central database biology research lab) hence why don't want put load on database storing user's sessions in database (although alternative, maybe set additional database sessions?). sessions used fair bit user's form inputs saved session using ajax (on change, persistence) , there can multiple instances of given form. facilliate garbage col

i understand causes runtime errors. want understand how browser behaves afterwards. will event handlers attached before error still work? if script loaded async finishes after runtime error able execute? basically, how catastrophic run-time error? an uncatched runtime error stops current execution, may be the execution of script the call of event handler suppose have runtime error while handling event, problem might have (apart not handling event) non consistent state of user variables if event handler modifies of them. other event handlers won't impacted besides that. so can considered non catastrophic (i guess don't have remember it's practice fix errors anyways , flooding console errors isn't thing).

i have web api method like; [httpget, route("users")] public httpresponsemessage getusers([fromuri] usersearchdto searchparams) {} the searchparams optional parameter when pass no search values , use http://api-uri/users becomes null , have add check in body of method avoid null reference exception. is there way using actionfilters or else inject default value parameter of web api method avoid if (searchparams == null){ searchparams = new usersearchdto () } not know of. honestly, you're doing pretty it. if want make bit neater, yo can condense null check 1 line so: searchparams = searchparams ?? new userseachdto();

i got problem getimagesize() . occurs when upload image but.. sometimes. the script should check image size avatar (profile-pic). if lower or equals 200px x 200px it's ok. i'm not done script yet, security things missing. i'm totally confused why happens , why happens. my script: //updateavatar if(isset($_files['uploadavatar']) , (isset($_session['user']) or isset($_session['dev']))) { //upload $uploaddir = "../img/avatar/";//relative path (we're in php folder [one step img]) $avatarextension = pathinfo($_files['uploadavatar']['name'], pathinfo_extension);//avatar extension (jpg,png,gif) if($avatarextension == "gif" || $avatarextension == "jpeg" || $avatarextension == "jpg" || $avatarextension == "png") { $_files['uploadavatar']['name'] = $loginname."_avatar".".".$avatarextension;//build new name (max 4 differe

i using vs 2013 express, desktop. regularly tear off doc tabs , put doc on other monitor. adds icon windows taskbar each floating doc. how stop that? wasteful of space not "combine" icons on taskbar (and never will). thanks actually windows behavior rather vs-specific behavior , can see in other applications (e.g. google chrome, error pop-ups in apps, etc.) , has simple rationale behind allow user switch between application windows. makes lot of sense otherwise you'll have mess many windows in order unhide window you'd work with. i'm unaware of way change behavior of windows , per above tend believe intentionally not possible.

i have nested array: array ( [id] => 1 [name] => group 1 [0] => array ( [id] => 1 [name] => group 1 ) [1] => array ( [id] => 2 [name] => group 2 ) [2] => array ( [id] => 7 [name] => group 7 ) ) and extract sub arrays [0] , [1] , , [2] in 1 single array following format: array( [id] => [name] ) in other words have result: array ( [1] => group 1 [2] => group 2 [7] => group 7 ) *note: tried set::classicextract($my_array['group'], '{n}.name'); can't figure out how group.id key array. guidance appreciated. this should work you: (here first array_filter() values out, don't have numeric key. after array_combine() id column name column array_column() ) <?php $result = array_filter($arr, function($k){ return is_numeric($k);

i'm using nested set represent nested comments (1 discussion has many comments, comments can replied to) , (if possible) eager load answers comments. at moment load root nodes , iterate on them, if have descendants render them. however, if there lot of root nodes answers, triggers lot of db requests. a comment has these columns: rgt, lft, parent_id i tried create relationship this: class comment < activerecord::base has_many :answers, -> (node) { where("lft > ? , rgt < ?", node.lft, node.rgt) }, class_name: "comment", foreign_key: :parent_id end this fetches answers comment when called on comment instance. however, if try eager_load ( discussion.comments.includes(:answers) ) blows since node nil. is possible eager load this? i think, i've found solution. if see right, data model looks this: discussion ---------- ... comment ---------- discussion_id:int parent_id:int lft:int rgt:int then ar model classes be: cla
