| Aggregate with respect to condition Posted: 21 Nov 2021 07:56 AM PST I face the following problem. I have a dataset that I simplify this way df <- tibble(ID_1=c("a","a", "a","a", "a", "b", "b", "b", "b"), ID_2 = c("a","b", "c","d", "e", "b", "a", "c", "d"), other= c(1, "bu", 34, 3, 5, 6, "jud", 82, 9), exchange=c(1, 13, 34, 3, 5, 6, 8, 82, 9), goods=c("wood","wood", "wood","wood", "wood", "steel", "steel", "steel", "steel")) df
We have exchanges between multiple countries that have different IDs. I want to sum all the exchanges between country A and country B. Between country A and country C. etc. the goods exchanged. That is, in the end, I'd like to have ID_1 // ID_2 // Sum_exchangeAB
ID_1 // ID_3 // Sum_exchangeBC
....
ID_n // ID_n // Sumexchangenn How can I do that in Dplyr? I tried group_by (ID_1, ID_2) then aggregate. Or summarise. Thank you for your help, much appreciated!! |

class Cartoon { . . } List<Cartoon> L1 = []; …. ... List<Cartoon> L2 = [];
I define below a new list L2 containing objects from List L1 meeting some condition List<Cartoon> L2 = []; L2.clear(); for (Cartoon _thisObjet in L1) { if (_thisObjet.xxx == yyyy) { // L2.add(_thisObjet); } }
I check with the debugger that anytime I modify a member Value in an Object L2 , the member is is also modified in member of. original Object in List L1. This is not expected result In my mind I was thinking these 2 Lists should be independent ,So if someone has an explanation, I would be grateful |

| How to get C to ignore spaces in scanf? Posted: 21 Nov 2021 07:55 AM PST I am working on a program that takes in a 32 digit number and inputs it into an array. However, this 32 digit number includes spaces in between certain numbers for example, the number: 11000010111110100000000000000000 could be typed as 1 10000101 11110100000000000000000.
When the latter is used, the program would not work. Is there a way for me to get C to ignore the spaces?
This is my code:
int arr[32]; char number[33] = {}; printf("Enter \n"); scanf("%34s", number); // This will scan max 32 characters printf("\n"); for (int i = 0; i < 32; i++) { { arr[i] = number[i] - '0'; } }

| Cannot decode UTF-8 buffer to desired data structure Posted: 21 Nov 2021 07:55 AM PST Before marking this question as a duplicate , I must state that I am aware of the other posts that transform a buffer in an array of buffers (I have been trying virtually every thread's comments on this , but is not what Im looking for). I am using Node's child process to run a python script .The script returns a list in the form of : [["a","21","67"],["b","22","69"]]
As per the Node child process docs , the result is UTF8 encoded. The problem is that whenever I try with textDecoder : const response=new TextDecoder(data).decode(data);
or with regex: var response = data.toString() var ressult= a.match(/\d+/g);
None of them (and many variations of them that I have tried) works as I expect. Ultimately , I just want to get a javascript array ( [["a","21","67"],["b","22","69"]] ) so that I can perform functions on it(or , in other words, the list returned from the python script).Thank you ! |

| Javascript IF/ELSE - Shorten function Posted: 21 Nov 2021 07:56 AM PST I am playing around with the JavaScript IF/ELSE to understand better how it works. As an exercise I took the following working hours of a shop: - 6AM to 6PM = Open
- 6PM to 6AM = Closed
then I created a function that returns the word 'Open' or 'Closed' based on the 2 values "time" and "period". function shopHours(time,period) { if (time === 6 && period === 'AM') { return 'Open'; } else if (time === 6 && period === 'AM') { return 'Open'; } else if (time === 7 && period === 'AM') { return 'Open'; } else if (time === 8 && period === 'AM') { return 'Open'; } else if (time === 9 && period === 'AM') { return 'Open'; } else if (time === 10 && period === 'AM') { return 'Open'; } else if (time === 11 && period === 'AM') { return 'Open'; } else if (time === 12 && period === 'PM') { return 'Open'; } else if (time === 1 && period === 'PM') { return 'Open'; } else if (time === 2 && period === 'PM') { return 'Open'; } else if (time === 3 && period === 'PM') { return 'Open'; } else if (time === 4 && period === 'PM') { return 'Open'; } else if (time === 5 && period === 'PM') { return 'Open'; } else { return 'Closed';} }
Everything works fine. However, I would like to be able to shorten the code as it looks too confusing. I then tried the following: function shopHours(time,period) { if(time <= 6 && period === 'AM') { return 'Closed'; } else if (time >= 6 && period === 'PM') { return 'Closed'; } else if (time === 12 && period === 'PM') { return 'Open'; } else { return 'Open';} }
The second code works fine too and is much shorter however there is a problem that I am not sure how to solve. When the time and period are set to 12 and PM, the result should be 'closed' but I am not sure how to implement this. I have tried to add the following code but it seems that would not solve this problem. else if (time === 12 && period === 'AM') { return 'Closed'; }
I will be very grateful to anyone that will spend a bit of his time to take a look at this question. Thank you! |

then the my publiccontainer have 3 sub routes "/" "/product" "/mycart" /* Dependencies */ import { Route, Switch, BrowserRouter as Router } from 'react-router-dom' /* Components */ import Header from "../../Components/Header" import Products from "./Products" import Home from "./Home" import UserProfile from "../User/AccountProfile" import MyCart from '../Public/MyCart' const PublicContainer = () => { console.log("PUBLIC") return ( <div> <Router> <Header /> <Switch> <Route exact path='/' render={(props) => <Home />} /> <Route exact path='/products' render={(props) => <Products />} /> <Route exact path='/mycart' render={(props) => <MyCart isAuth={false} />} /> </Switch> </Router> </div> ) } export default PublicContainer
the my cart component will only render if isAuth is true, else it will redirect to "/auth/signin" import React from 'react' import { Redirect } from 'react-router' const MyCart = ({isAuth}) => { if(!isAuth) return (<Redirect from='*' to='/auth/signin'></Redirect>) return ( <div> my cart </div> ) } export default MyCart
The problem is, its trying to redirect to "/auth/signin" but it is still in the "/" page  When i hit reload it finally redirect to "/auth/signin" How can i fix this issue, I really appreciate your help UPDATE this is overview of my planned routes  By the way i think when the mycart isAuth is false then it tries to Link to /auth/signin which causes the link in the top url to correctly point to auth signin, but after that it only checks the routes of the publiccontainer instead of checking the app routes  But when i reload it, it start searching the correct route from the app.js routes which return the expected route & page which is the sign in

| Create new record based upon the presence of a record with Rails Posted: 21 Nov 2021 07:55 AM PST I've got a rails app that has two models: address and delivery, where address has_many :deliveries and delivery belongs_to :address. I'm attempting to create a means by which a single POST request can search to find a matching address in the addresses table using parameters provided in the request, if a match is found create a new delivery. If no address is found, then error the request. Here's what I have so far (not functional, but hoping I'm close(ish)): Controller class DeliveriesController < ApplicationController before_action :confirm_address, only: %i[ create edit update ] protect_from_forgery with: :null_session, if: Proc.new {|c| c.request.format.json? } def index render json: Delivery.all end def create # Delivery.address_id = Address.find_by(numeric: params[:numeric], street_name: params[:street]) # @address_of_delivery = Delivery.includes(:address).where(numeric: params[:numeric], street_name: params[:street_name], city: params[:city], state: params[:state], zip: params[:zip]) delivery = Delivery.new(delivery_params) # @confirmed_address.id = self.address_id puts 'putting' # puts @address_of_delivery if delivery.save render json: {status: 'Awesome!', data: delivery}, status: :ok else render json: {status: 'Boo!', data: delivery.errors}, status: :unprocessable_entity end end private def delivery_params params.permit(:company, :numeric, :street_name, :city, :state, :zip) end def confirm_address @confirmed_address = Address.find_by(numeric: params[:numeric], street_name: params[:street_name], city: params[:city], state: params[:state], zip: params[:zip]) if @confirmed_address.present? puts "found one!" else puts "NO DICE" # self.address_id = confirmed_address.id end end
As you can see from the controller, I've attempted several paths including using includes and join(not included in snippet), as well as trying to just hard code it. Also tried to solve through the model, but had trouble accessing the params from the POST request: class Delivery < ApplicationRecord belongs_to :address # accepts_nested_attributes_for :address attribute :numeric attribute :street_name attribute :city attribute :state attribute :zip before_validation :find_associated_address def find_associated_address Address.find_by(numeric: params[:numeric], street_name: params[:street]) puts 'working in model' end end
Copy of the POST request for clarity: Started POST "/deliveries" for ::1 at 2021-11-20 22:52:00 -0600 Processing by DeliveriesController#create as */* Parameters: {"company"=>"slowcart", "numeric"=>"123", "street_name"=>"Any Street", "city"=>"NYC", "state"=>"NY", "zip"=>"010101"}
I'm almost certainly making a stupid mistake, but can't find the right means to do what I want to do in the docs/broader web. Rails 6 application, btw. |
| Redux state being overwrite after changing another state Posted: 21 Nov 2021 07:55 AM PST I have a problem with Redux, when I change view and I make an API call to retrieve data, and I go back to my other view, the data is overwritten by "undefined", yet the two states have no incidence between them.

| How to Log in F# in a functional way using NLog Posted: 21 Nov 2021 07:55 AM PST I have been looking at logging options and settled on NLog and logging to a database I am fairly new to functional programming and have come from a background in C# OOP. How would I implement logging in a functional way in F#?
Do I - Create the logger at the top level and just pass it in to every function as I go
- Access the logger through a static method as needed ( obviously there would be some overhead to instantiating a logger each time - but maybe that's not a big deal )
- Something else?
I want to avoid using a commercial logging option just because my projects are quite small. Thanks for your time. |
| How to detect the text in Image using opencv and save result in CSV Format Posted: 21 Nov 2021 07:56 AM PST Hello Everyone I have the image in which the data is shown in notepad. I want to crop the notepad area, detect the text row-wise and save the result in CSV format I have tried the following but it does not give good results. 
# Load the libraries import cv2 import pytesseract # Load the image img = cv2.imread("/content/20211026_095828.jpg") # Convert it to the gray-scale gry = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) # OCR detection d = pytesseract.image_to_data(gry, config="--psm 6", output_type=pytesseract.Output.DICT) # Get ROI part from the detection n_boxes = len(d['level']) # For each detected part for i in range(n_boxes): # Get the localized region (x, y, w, h) = (d['left'][i], d['top'][i], d['width'][i], d['height'][i]) # Draw rectangle to the detected region cv2.rectangle(img, (x, y), (x+w, y+h), (0, 0, 255), 1) # Crop the image crp = gry[y:y+h, x:x+w] # OCR txt = pytesseract.image_to_string(crp, config="--psm 6") print(txt) plt.imshow(img)
Any guidance here would be very helpful. |
| android how to avoid close of Toolbar's SearchView EditText line on UI update? Posted: 21 Nov 2021 07:55 AM PST I have a SearchView in my Toolbar for a RecyclerView list of CardViews and they are saved in a Room database. I filter the list with search text via the SearchView and then left-swipe one of the returned Cards to delete it from the database. The UI updates properly to show any remaining filtered CardViews. Problem is when I click "x", the close button that I set up to the right of the search EditText line. The filtered list disappears correctly after the left-swipe to delete the filtered card and the UI updates the new list of the remaining CardViews in the database correctly. However, during the update of the UI, the search EditText line and the "X" close button are destroyed and the Toolbar returns to showing the default state for the SearchView that I set up, which is to show the search icon as iconified. However, I would like to keep the search EditText line open, clear the search text and keep the "x" close button to the right of the EdixtText line after the UI is updated. I tried adding the below code snippets to the mSearchView, the searchItem and the mSearchEditText variables, to try to re-open the search EditText line after the UI update, with no luck: .setIconified(false); .performClick(); .expandActionView(); .requestFocus(); I also put the ViewModel update for the Room database in a background thread with an ExecutorService and then tried to update the UI and clear the search EditText line on the main thread, after the background thread had completed. But the search icon as iconified was still returned. So what am I missing? How can I achieve? MainActivity.java @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.mainactiv_menu, menu); searchItem = menu.findItem(R.id.action_search); menu.findItem(R.id.action_search).setVisible(false); if (cardsAdapter != null && cardsAdapter.getItemCount() > 0) { menu.findItem(R.id.action_search).setVisible(true); } SearchManager searchManager = (SearchManager) MainActivity.this.getSystemService(Context.SEARCH_SERVICE); if (searchItem != null) { mSearchView = (SearchView) searchItem.getActionView(); mSearchView.setOnQueryTextFocusChangeListener(new SearchViewFocusListener(searchItem)); if (mSearchView != null) { mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); mSearchEditText = mSearchView.findViewById(androidx.appcompat.R.id.search_src_text); mSearchEditText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS); mSearchEditText.setMaxLines(1); ImageView closeButton = mSearchView.findViewById(R.id.search_close_btn); closeButton.setOnClickListener(v -> { // gets the data from the Room database. mQuickcardViewModel.loadFullList(); // reload the database data in to the RecyclerView Adapter. This destroys // the search EditText line for the SearchView and also destroys the "x" close // button and the search icon re-appears. cardsAdapter.reloadFullList(mQuickcards); // Clear the current search text so the member can enter different search text. // This is not working as the UI shows the search icon as iconified. mSearchView.setQuery("",false); }); mainactiv_menu.xml <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" tools:context=".MainActivity"> <item android:id="@+id/action_search" android:title="@string/search_title" android:icon="@drawable/ic_action_search" app:actionViewClass="androidx.appcompat.widget.SearchView" android:orderInCategory="1" app:showAsAction="always|collapseActionView" /> <item android:id="@+id/action_new" android:title="@string/action_new" android:icon="@drawable/ic_action_new" tools:targetApi="o" android:tooltipText="Add a quickcard" android:orderInCategory="2" app:showAsAction="always" /> <item android:id="@+id/action_overflow" android:title="@string/action_overflow" android:icon="@drawable/ic_action_overflow" android:orderInCategory="3" app:showAsAction="always" > <menu> <item android:id="@+id/number_of_cards" android:title="" app:showAsAction="always" /> </menu> </item> </menu>

| define a failure horizon based on serial number and failure label Posted: 21 Nov 2021 07:55 AM PST I wanted to re-label the healthy label (0) to failure label (1) 3 days before the actual failure (1) like what they did in the attached link: Reference link. It worked well for the equal time length but did not work for the variable length. That is, all serial number must fail in the same day which doesn't make sense. For the sample dataset, we see that serial C failed in January 5, 2014, A failed in January 6, and A failed in January 7. I want to relabel the re-label the healthy label (0) to failure label (1) 3 days before the actual failure (1) for the serial number C, and for the other serial numbers as well. I appreciate your time. Thanks! My code: import pandas as pd import numpy as np import datetime from datetime import date, timedelta df = pd.read_excel('/content/failure.xlsx') df['date'] = pd.to_datetime(df['date']) df = df.sort_values(by="date") d = datetime.timedelta(days = 3) a = [] for ind in df.index: if df['failure'][ind] == 1: sdate = df['date'][ind] - d edate = df['date'][ind] delta = edate - sdate for i in range(delta.days + 1): day = sdate + timedelta(days=i) a.append(day) mylist = list(dict.fromkeys(a)) mylist = pd.to_datetime(mylist,format='%y/%m/%d') new_value = 1 for ind in df.index: for item in mylist: if df['date'][ind].date() == pd.to_datetime(item).date(): df['failure'][ind] = 1

| Databricks - is not empty but it's not a Delta table Posted: 21 Nov 2021 07:56 AM PST I run a query on Databricks: DROP TABLE IF EXISTS dublicates_hotels; CREATE TABLE IF NOT EXISTS dublicates_hotels ...
I'm trying to understand why I receive the following error: Error in SQL statement: AnalysisException: Cannot create table ('default.dublicates_hotels'). The associated location ('dbfs:/user/hive/warehouse/dublicates_hotels') is not empty but it's not a Delta table I already found a way how to solve it (by removing it manually): dbutils.fs.rm('.../dublicates_hotels',recurse=True)
But I can't understand why it's still keeping the table? Even though that I created a new cluster (terminated the previous one) and I'm running this query with a new cluster attached. Anyone can help me to understand that? |
| the <script> tag with the jQuery library reference must be inside <head> or <body> tag? [duplicate] Posted: 21 Nov 2021 07:56 AM PST Possible Duplicate:
Where should I put tags in HTML markup? I always thought that it's better to put it in the head (maybe because it is loaded first in the head and also to group all the scripts in the head for easy reading), but I found several examples over Internet (Bootstrap documentation, ASP.NET MVC 4, etc.) where the script tag with the reference to jQuery (</ script>) is inserted into the body: <!DOCTYPE html> <html> <head> <title>Bootstrap 101 Template</title> <!-- Bootstrap --> <link href="css/bootstrap.min.css" rel="stylesheet"> </head> <body> <h1>Hello, World!</h1> <script src="http://code.jquery.com/jquery-latest.js"></script> <script src="js/bootstrap.min.js"></script> </body> </html>
