| react className conditional setting according to all of state Posted: 06 Jul 2021 08:08 AM PDT I currently making a vocabulary website and got state from mysql, and the state is like this. 1: memorize : 0 2: memorize : 0 3: memorize : 0 4: memorize : 0 5: memorize : 1 6: memorize : 0
So if I check the checkbox on the list of website, each state turns to 1. and 0 means not checked. every time check the box, it changes the value of state(from0 to 1) and what I want to make is the button(finish) that active&disable. If all of the state turn in to 1, I want to make this finish button active. So I decided to make 2 className, active, notActive, however it is really hard to make the condition. How to use "If" structure to examine all state? I have tried using State.map, but this only works when examine each state, not whole. in conclusion, I want to make useEffect(() =>{if( all of the state === 1){ buttonClassName = active}}
could you tell me how to embody"all of the state" ?  |
| UICollectionView nested in a UIScrollView loads all cells at once Posted: 06 Jul 2021 08:08 AM PDT I have a few very long collectionViews, all nested inside a scrollView. since the prefetching range is related to the scrollView, all the cells are "visible" on the scrollView, even though most of them are not visible on the screen at all. Hence, when calling reloadData(), it reloads all the cells, instead of reloading only the visible cells. it ends up in a very long UI freeze. Is there a way to load only the cells that are truly visible on the screen?  |

| React: Mapping a value through an object to return an SVG Posted: 06 Jul 2021 08:08 AM PDT I'm trying to pass a value from a parent component (that renders a label) and hopefully soon an icon down into my CountryFlag component. So far it's being passed like so: <CountryFlag countryCode={option.code} />
option.code returns a countryCode such as "AFN".
I then want to take that countryCode into my CountryFlag component and map through my CountryMap array so that if for example, "AFN" is passed through from the parent component, I will be able to return the "Afghan" SVG as part of the rendered FlagComponent. I know I'm still a bit off the final implementation but any suggestions on where I may go next would be really appreciated. import Afghanistan from "./CountryFlags/Afghanistan.svg"; import Albania from "./CountryFlags/Albania.svg" import styled from "styled-components"; const countryMap = { AFN: { countryCode: "AFN", name: "afghanistan", icon: Afghanistan, }, ALL: { countryCode: "ALL", name: "albania", icon: Albania, }, }; const StyledImage = styled.div` height: 32px; width: 32px; `; const CountryFlag = ({className, code="" }: Props) => { const FlagComponent = countryMap[code]; if (!FlagComponent) { console.warn(`icon for ${code} is not valid`); return null; } return ( <StyledImage> <FlagComponent> src={} </FlagComponent> </StyledImage> ); } export default CountryFlag;

| Overriding GetHashCode() - how important is random distribution of hashes? Posted: 06 Jul 2021 08:07 AM PDT In anticipation of first comments, I do understand some hash table theory so please read on... I have a mutable reference type (contents can change) that is used as key in a Dictionary. Yes this is intentional (in fact unavoidable). The Dictionary grows to millions of entries and I wish to optimise access by key. My objects do have a guaranteed-unique, private, integer field which seems a potentially ideal hash code in that underlying hashtable collisions would be impossible, however these are (nearly) sequential 1,2,4,5,6,9,10,11,... In Principle : Should I do this public override int GetHashCode() { return myUniqueId; }
or this public override int GetHashCode() { return GenerateRandomInt(seed:myUniqueId); // where a 1:1 relationship exists between input seeds and output pseudo random numbers // (still avoiding hash collisions but at the cost of the PRNG call) }
from a hashtable-theory / best-practice point-of-view, or is the answer likely to be implementation-specific (I'd have to measure - probably per deployment environment)? Eric Lippert mentions random distribution as a "guideline" in this blog article: Lippert Fabulous adventures in coding  |

My algorithm encrypts blocks of 36 bytes and the last block is padded with the original block. The encryption function is simple but when it encrypt sometimes it encrypt less characters and other times it just take a part from the Text-criptat.txt to decrypt. The number of characters in Text-criptat.txt and Text-decriptat.txt it just isn't equal with the one in the original file. Please help! Thanks! #include <iostream> #include <fstream> #include <string> #include <stdio.h> using namespace std; string key; void reverseStr(string& str) { int n = str.length(); for (int i = 0; i < n / 2; i++) swap(str[i], str[n - i - 1]); } string paddingdata(string str) { int x = 36; for (int i = 0; ; i++) { if (x == i) i = 0; if (str.size() == x) break; str.push_back(str[i]); } return str; } string swifting(string& str, string key, int k) { if (k == 0) { for (int i = 0; i < str.length(); i++) { if (i % 2 == 0) { str[i] = str[i] + key[i]; } else { str[i] = str[i] - key[i]; } } } else { for (int i = 0; i < str.length(); i++) { if (i % 2 == 0) { str[i] = str[i] - key[i]; } else { str[i] = str[i] + key[i]; } } } return str; } string XOROP(string data, string key) { string dataaux = data; for (int i = 0; i < dataaux.size(); i++) { dataaux[i] = data[i] ^ key[i]; } return dataaux; } string expandKey(string keyword) { int x = 36; for (int i = 0; ; i++) { if (x == i) i = 0; if (keyword.size() == x) break; keyword.push_back(keyword[i]); } return keyword; } // Se modifica cheia. string modifyKey(string key) { string dataaux = key; for (int i = 0; i < key.size(); i++) { char p = key[i]; for (int j = i + 1; j < key.size(); j++) { p += key[j]; } dataaux[i] = key[i] ^ p; } reverseStr(dataaux); return dataaux; } string encryption(string keyx, string data) { for (int i = 0; i < data.length(); i++) { reverseStr(data); data = swifting(data, keyx, 0); data = XOROP(data, keyx); } return data; } string decryption(string keyx, string data) { for (int i = 0; i < data.length(); i++) { data = XOROP(data, keyx); data = swifting(data, keyx, 1); reverseStr(data); } return data; } void afisarefisiercriptat(string s) { fstream fpt; fpt.open("Text-criptat.txt", fstream::out); if (!fpt) { cout << "\nEroare"; return; } fpt << s; fpt.close(); } void afisarefisierdecriptat(string s) { fstream fpt; fpt.open("Text-decriptat.txt", fstream::out); if (!fpt) { cout << "\nEroare!"; return; } fpt << s; fpt.close(); } int main() { bool encrypt = true; string encryptinput, input, encryptmessage = "", message = "", decryptmessage = ""; cout << "C for encrypt/ D for decrypt: "; getline(cin, encryptinput); if (encryptinput == "d" || encryptinput == "D") { encrypt = false; } cout << "Insert the KEY: "; getline(cin, key); string auxkey = expandKey(key); cout << "Extended key is: " << auxkey << endl; char ch; string fileName; fstream fps, fpt; cout << "Name of the file: "; cin >> fileName; fps.open(fileName, fstream::in); if (!fps) { cout << "\nEroare!"; return 0; } while (fps >> noskipws >> ch) { input = input + ch; } cout << "The text is : " << input << endl; fps.close(); if (encrypt) { if (input.size() <= 36) { message = paddingdata(input); auxkey = modifyKey(auxkey); message = encryption(auxkey, message); afisarefisiercriptat(message); } else { int x = 0; int t = 0; int r = input.size() % 36; // int e = input.size() / 36; // while (x == 0) { cout << "Starting encrypting the block " << t << endl; for (int i = 36 * t; i < 36 * (t + 1); i++) { message += input[i]; } auxkey = modifyKey(auxkey); encryptmessage += encryption(auxkey, message); cout << "The encrypted message after encrypting the block " << t << " is: " << encryptmessage << endl; if (e == t + 1) x = 1; message = ""; t++; } if (r > 0) { string lastblock = ""; cout << "Starting encrypting the last block " << endl; for (int i = 0; i < r; i++) { lastblock += input[e * 36 + i]; } lastblock = paddingdata(lastblock); auxkey = modifyKey(auxkey); encryptmessage += encryption(auxkey, lastblock); cout << encryptmessage << endl; } afisarefisiercriptat(encryptmessage); } } else { int x = 0; int e = input.size() / 36; int t = 0; for (int t = 0; t <= e - 1; t++) { cout << "Starting decrypting block " << t << endl; for (int i = 36 * t; i < 36 * (t + 1); i++) { message += input[i]; } auxkey = modifyKey(auxkey); decryptmessage += decryption(auxkey, message); cout << "The decrypted message after the block " << t << "is: " << decryptmessage << endl; message = ""; } afisarefisierdecriptat(decryptmessage); } return 0; }
So i tried for days to understand why it doesn't work sometimes so.. i entered an input in a file: Unlike the radar, which knows which direction it is sending its signal, the receiver simply gets a pulse of energy and has to interpret it. Since the radio spectrum is filled with noise, the receiver's signal is integrated over a short period of time, making periodic sources like a radar add up and stand out over the random background. The rough direction can be calculated using a rotating antenna, or similar passive array using phase or amplitude comparison. And in the encrypted file(Text-criptat.txt) it shows me something like this: 쉕⇄䖗䣜洠⸌�൙렊ퟬ璣⯜꼂�圌瑣㙩ﬕℬ鈷椼⃔댡歼٭祬꼲鸞μ뭄꼡愾吨찐┸芰掕꧕ꇆ兟䆤辐겍碣뀝⍤탕⚯귘⇮䜂棹뙑�䅘桳垄к狵퀽礠癜Ϙ渭핣연ꪰ갡뽡ᾐ즌搳핲}殍吙ꗤ僼ꃴ誐এ䗃耬怄賥녒褣ᘱ剥㭋섚遴㮍夀呮ꆆ熰堤諳晝綐⌀㜈ⱚ炸ሕ입桰ڏ듘◝�浘ꏱ�w⧰連悿持猀䗯䍲쭥菙ꀡ惩᧲醜�ꓡ磤硵촠곎獸䄌샆ᏼ갹㼀斖傚栤삾浯በ⌡䮻鎲噠氐鷨鈀쇷碯惘軵ꝉ𠉯껁䫴�팼⒕鳩갥嗘ꆻ枎⇨ൈ輊ᅔ꾶ꔀⓢ⺥්副篠ﴭ䳙滋梘팡臻◠犚릹餀엯Ꜯ䓘턌꾰�괙䱐ၹ퀭壡偍爡㬑ḯﳖР鍁 In the encrypted file there are 236 characters, 7 more bytes than in the original file, maybe because the last block of 36 characters it's padded, it adds more characters until there is a fix number of blocks of 36 chars. So now i understand it isn't about characters it's all about bytes but i don't know why it doesn't decrypt properly, because the result in the decrypted file using the same key is: Unlike the radar, which knows which direction it is sending its signal, the receiver simply gets a pulse of energy and has to interpret it. Since the radio spectrum is filled with Here there are only 180 characters. My algorithm encrypts and decrypts only 36 bytes at a time so it decrypted only 5 blocks of data and i don't know why. It only happens when it shows me that chinese/koreean encryption in the encrypted file. Otherwise it works. I think there must be a character that c++ can't take it from the encrypted file and it just stops. Please help. THx!  |
| Python: iterate through the rows of a csv and calculate date difference if there is a change in a column Posted: 06 Jul 2021 08:08 AM PDT Only basic knowledge of Python, so I'm not even sure if this is possible? I have a csv that looks like this: [1]: https://i.stack.imgur.com/8clYM.png (This is dummy data, the real one is about 30K rows.) I need to find the most recent job title for each employee (unique id) and then calculate how long (= how many days) the employee has been on the same job title. What I have done so far: import csv import datetime from datetime import * data = open("C:\\Users\\User\\PycharmProjects\\pythonProject\\jts.csv",encoding="utf-8") csv_data = csv.reader(data) data_lines = list(csv_data) print(data_lines) for i in data_lines: for j in i[0]:
But then I haven't got anywhere because I can't even conceptualise how to structure this. :-( I also know that at one point I will need: datetime.strptime(data_lines[1][2] , '%Y/%M/%d').date()
Could somebody help, please? I just need a new list saying something like: id jt days 500 plumber 370 Edit to clarify: The dates are data points taken. I need to calculate back from the most recent of those back until the job title was something else. So in my example for employee 5000 from 04/07/2021 to 01/03/2020.  |

| Escape double quotes in a string Posted: 06 Jul 2021 08:09 AM PDT Double quotes can be escaped like this: string test = @"He said to me, ""Hello World"". How are you?";
But this involves adding character " to the string. Is there a C# function or other method to escape double quotes so that no changing in string is required?  |
