php - Magento 2 event observer not working -


i'm trying create simple event observer magento 2 page.

app/code/ndac/orderinfo/etc/event.xml

<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:nonamespaceschemalocation="urn:magento:framework:event/etc/events.xsd">     <event name="sales_order_place_after">        <observer name="orderinfo" instance="ndac\orderinfo\observer\orderinfo" />    </event>  </config>

app/code/ndac/orderinfo/etc/module.xml

<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:nonamespaceschemalocation="urn:magento:framework:module/etc/module.xsd">     <module name="orderinfo" setup_version="1.0.0"></module> </config>

app/code/ndac/orderinfo/registration.php

<?php \magento\framework\component\componentregistrar::register(\magento\framework\component\componentregistrar::module,"orderinfo", __dir__);

app/code/ndac/orderinfo/observer/orderinfo.php

<?php namespace ndac\orderinfo\observer;  use magento\sales\model\order; use magento\framework\event\observer; use magento\framework\event\observerinterface;  class orderinfo implements observerinterface {     // tried constructor     public __construct() {         $file = fopen("/mnt/data/magento/test.txt", "w") or die ("die");         fwrite($file, "test");         fclose($file);     }      public function execute(observer $observer)     {         $file = fopen("/mnt/data/magento/test.txt", "w") or die ("die")         fwrite($file, "test");         fclose($file);     } } ?>

i run following command: bin/magento setup:upgrade , module appears on dashboard, , enabled, test.txt remains empty, after place order.

there issue file naming. 

app/code/ndac/orderinfo/etc/event.xml

this has as:

app/code/ndac/orderinfo/etc/events.xml

it has events.xml . , if event doesnt work, try checkout_onepage_controller_success_action event.

now run upgrade , clear cache.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
