i'm facing odd issue, carbon::parse("25/10/1980") throws following error: exception message 'datetime::__construct(): failed parse time string (25/12/1980) @ position 0 (2): unexpected character' while having no problems whatsoever, if month (10) swapped places day (25) this: carbon::parse("10/25/1980") how should parse "d/m/y" string? try this: carbon::createfromformat('d/m/y', '25/10/1980')

so have component, , let's when click on should trigger state change, e.g.: :on-click #(om/set-state! {:activated? true}) now, if want "deactivate" when clicked anywhere on document? guess use addeventlistener hooking onto document object, this: (componentdidmount [this] (events/listen (gdom/getdocument) (.-click events/eventtype) #(om/set-state! {:activated? false}) true)) now want, first of if have 200 instances of same component have 200 event listeners, right? which not desirable ok, guess the real question though how distinguish 1 instance of component when setting state? don't want of them "deactivated", 1 in context click event handler being triggered i think title of question points real problem: global events affecting local state. sounds me notion of being "activated" doesn't belong each of these components (as local state), higher in tree. otherwise, they'd function independently.

i have http spring security configuration appears work when comment out each individual aspect doesn't work when combine spring security rules together, know problem not regexmatcher or antmatcher rules applied in combination. here spring security class: package com.driver.website.config; import org.springframework.beans.factory.annotation.autowired; import org.springframework.beans.factory.annotation.value; import org.springframework.context.annotation.bean; import org.springframework.context.annotation.configuration; import org.springframework.security.config.annotation.authentication.builders.authenticationmanagerbuilder; import org.springframework.security.config.annotation.method.configuration.enableglobalmethodsecurity; import org.springframework.security.config.annotation.web.builders.httpsecurity; import org.springframework.security.config.annotation.web.builders.websecurity; import org.springframework.security.config.annotation.web.configuration.enablewebsecurit

433 mhz receiver arduino environment the transmitter sends y , n or m works fine. problem lies in receivers code. goal is, after receiver has value message equal n, suppose trigger if statement thing. need have system can determine if receiver takes in specific value. void loop() { if (vw_get_message(message, &messagelength)) // non-blocking { serial.print("received: "); (int = 0; < messagelength; i++) { serial.write(message[i]); const char *p = reinterpret_cast<const char*>(message); if(p == "n") { serial.print("if statement works when = n"); } } } } the problem, not job, , after 2 weeks of struggle, @ loss. code compile , run, if statement ignored. if (p=="n") compares 2 pointers. while contents point can identical, not mean pointers equal. you may want strcmp (c style) or std::string::

i have 2 divs want display on same row (one on left, other on right). the left div: .leftdiv { position: relative; display: inline-block; width : 30%; } the right one: .right-div { float : right; width : 40%; background-color: lime; } the left div wraps 2 other divs: dropdown-content displayed after clicking on dropdiv . i want dropdown-content take half (50%) of page when set width 100% can not larger parent leftdiv (which must not exceed 30% of page). how fix this? js bin you can set 50vw (50% of viewport width).

i have 2 models associated has_one relationship. have callback initializes association. classes (roughly) this: class user has_one :relevance, class_name: 'user::relevance', inverse_of: :user, dependent: :destroy after_create :initialize_relevance def initialize_relevance self[:relevance] = user::relevance.new end # other garbage *should* irrelevant end class user::relevance belongs_to :user, inverse_of: :relevance, index: true # more other garbage *should* irrelevant end sometimes relevance association gets wonked state nil. when happens, want re-initialize relationship when called , return instead of nil. in class user , have this: def relevance self[:relevance] = user::relevance.new if self[:relevance].nil? self[:relevance] end except doesn't work , nil still returned. i've tried same update_attribute(user::relevance.new) , self.create_relevance nil seems returned. not sure go here , love ideas. can provide more code

what correct way use ember js three.js . have tried using cdn editing index.html file works fine warning in ember-cli three not being defined. installing bower , using app.import gave me similar warnings. the app works fine wanted know best way import in case three.js ember application without warnings. that jshint warning because isn't aware of global three variable you're trying access. have 2 ways fix it: put globals directive @ top of file uses variable. setup .jshintrc 's predef . hope helps!

please me below query , want check if string starts 'g' or 'f' in condition along existing condition. here query first query :- select top 1 lc_id, isnull(lc_ud, 0) record contract lc_id = 'f01' output f01 | 1 ( if available) else no record return. second query: if lc_id starts 'f%' or 'g%' how can integrate both query 1 if there no record available 'f01' value, check if lc_id starts f & g return output f04 | 1 else no record return. you want prioritize values being returned. because want one, can order by : select top 1 lc_id, coalesce(lc_ud, 0) record contract lc_id '[fg]%' order (case when lc_id = 'f01' 1 else 2 end); note: assumes using sql server (based on syntax).

so have bit of issue on hands. have list of tuples (made of level number , message) become html list. issues before happens, turn tuples values dictionary of nested dictionaries. here example: # have list of tuples in format of (level_number, message) tuple_list = [(1, 'line 1'), (2, 'line 2'), (3, 'line 3'), (1, 'line 4')] # , want turn a_dict = { 'line 1': { 'line 2': { 'line 3': {} } }, 'line 4': {} } any appreciated, long valid python 3. thanks! as pointed out in comment, should consider changing incoming data structure if have control @ on it. sequential list of tuples not ideal you're doing here. possible if treat tree. let's build (sane) data structure parse with class node(object): def __init__(self, name, level, parent=none): self.children = [] self.name = name self.level = level self.parent = parent def m

i have txt file output machine bunch of writing/data/paragraphs not used graphing purposes, somewhere in middle of file have actual data need graph. need search file data , print data txt file can graph later. the data in middle of file looks (with each data file potentially having different amounts of rows/columns , numbers separated spaces): <> 1 2 3 4 5 6 etc. 1.2 1.3 1.4 etc. b 0.2 0.3 0.4 etc. c 2.2 2.3 2.4 etc. etc. my thinking far grep '<>' find first line (grep '^<>' file) i'm not sure how account variable amount of rows/columns when trying find them. also, using awk loop on .txt files in directory , print new outfile can multiple files @ once (so maybe can search/printing in awk well?). edit: --input/expected output file-- input file this data here paragraphs <> 1 2 3 1.2 1.3 1.4 b 0.2 0.3 0.4 c 2.2 2.3 2.4 more paragraphs more paragraphs output file: <> 1 2

we're going develop uwp app , it'll mobile , desktop. in our presentation, our app universal, not testing or deploying on surface hub, holo lens , xbox? if refer first paragraph of official documentation : the uwp provides guaranteed core api layer across devices. means you can create single app package can installed onto wide range of devices. but: because uwp app runs on wide variety of devices different form factors , input modalities, want tailored each device , able unlock unique capabilities of each device. devices add own unique apis guaranteed api layer. can write code access unique apis conditionally app lights features specific 1 type of device while presenting different experience on other devices. so universal on condition not triggering platform specific api codes. , ui, uwp using adaptive ui let app fit different screen size.

i'm in process of upgrading our code base php5.4 php7. in our tests wrap entire test in transaction command mysql_query("begin"); then bunch of stuff mysql_query("rollback"); then between 2 commands treated transaction , rolled @ end of test. have not been able achieve functionality in php7 mysqli. tried using mysqli_autocommit function did not allow different queries within test have access created data earlier in test. if each insert in own transaction. update: the issue every time create new adapter table, seems creating new connection db. php5 , command above 'mysql_query("begin")' every connection contained in transaction , statements rolled back. have not found way php7. if use $mysqli->begin_transaction(); then single connection part of transaction. in order achieve desired functionality, have implicitly force every adapter use existing connection rather creating own. imagine there way php7 automatically you?
