| Vuetify: Changing hexcode of a color Posted: 25 Nov 2021 07:46 PM PST Is it possible to change the hexcode for the colors outlined on this page for Vuetify? Say I wanted to slightly alter the red color to something lighter. How could I do that? Per the docs I have something like this but I want to change the color directly: import Vue from 'vue'; import Vuetify from 'vuetify'; Vue.use(Vuetify); export default new Vuetify({ theme: { themes: { light: { primary: '#123456' } } } });

| What is the proper way to escape quotes and slashes when running a Jest test with --collectCoverageFrom from Powershell via npm scripts? Posted: 25 Nov 2021 07:45 PM PST I am a React developer, and am used to running commands like the example below from Bash in Linux, but now I have to make it work in a Windows environment from Powershell: npm test ExampleComponent --collectCoverageFrom='["**/ExampleComponent.tsx"]' --watch
The npm test script just has "jest" in it, but I need to use it via the script so that I am using the version of jest in the project, not a global. I use this when trying to fill-in gaps in code coverage in a specific file (ExampleComponent.tsx), so I want Jest to reassess the coverage for just that one file when I save changes to the test file (ExampleComponent.test.tsx in this case). This is what I ran in Powershell (Added the quotes in "--" because Powershell doesn't treat -- as bash does, and switched from forward slash to backslash for Windows): npm test "--" ExampleComponent --collectCoverageFrom='["**\ExampleComponent.tsx"]' --watch
This is how jest gets called as per the output from npm: jest "ExampleComponent" "--collectCoverageFrom=[**\ExampleComponent.tsx]" "--watch"
In Powershell (version 7.2, if that matters), the command above doesn't restrict the coverage check to the specified file. It does only test the specified file, but the collectCoverageFrom option is ignored presumably because the pattern jest receives is mangled by Powershell. How can I escape the quotes and slashes from a Powershell commandline to replicate the bash invocation at the top? Based on answers regarding escaping in Powershell, I've tried combinations of multiple backslashes and multiple quotes in a myriad of permutations, but none of them have worked so far. |
| How do I modify my code to add another submenu level to my CSS only, dropdown menu Posted: 25 Nov 2021 07:45 PM PST Hi and thanks in advance, I have some CSS that displays 3 levels of dropdown but I need it to work for the 4th level also.

| LINQ queries always sort by primary key value even when orderby clause explicitly calls to sort with a different value Posted: 25 Nov 2021 07:43 PM PST I am working on my first personal C# project and am incorporating LINQ to make queries against a SQL Server database. I am experiencing an issue with LINQ where queries always sort the records returned from the table according to their primary key value even though orderby clauses exist in the query. My objective is to query a table that includes columns for first name and last name (both of type varchar); sort by first name; then sort by last name. The problem code consists of two sections. The first is the original query: var dayShiftCrew = from information in context.EmployeeInformations where information.EmployeeShiftType.Shift == "Day" && information.EmployeePositionType.Position == "Crew" orderby information.EmployeeNamesAndNumber.FirstName, information.EmployeeNamesAndNumber.LastName select information.EmployeeNamesAndNumber;
The second part is a foreach statement that populates another table with the query results: foreach (var employee in dayShiftCrew) { var position = from selection in context.EmployeeInformations where selection.EmployeeID == employee.EmployeeID select selection.Position; string query2 = $@"USE Employees; INSERT INTO WeeklySchedule_{month}_{day}_{year} " + @"(EmployeeID, Name, Position) VALUES " + $@"({employee.EmployeeID}, '{employee.FirstName + (" ") + employee.LastName}', '{position.First()}');"; SqlCommand command2 = new SqlCommand(query2, connection); command2.ExecuteNonQuery(); }
When I view the destination table after it is populated, the records are not arranged according to the query's orderby clause. I have executed variations of this code multiple times, and each time the records appear in the same sequence. The sequence in the destination table matches the sequence in the original table, which leads me to think that either the query is sorting by the records' primary key value or is not sorting at all and simply returning the records in their original sequence. I'm sure that there is something that I'm overlooking, but I have been experimenting for a while with this code and cannot find a solution to sort correctly. I have tried both kinds of syntax for LINQ queries; tried using one orderby rule instead of two; and rewrote lines for immediate instead of deferred execution. Other specific details: The from clause refers to a table with a composite primary key that includes four foreign-key relationships. The query returns an IQueryable that contains the desired records, albeit in the wrong order. No exceptions are thrown at compile or runtime, and no other unexpected behavior is occurring apart from this. |

I was confident it was bubble sort at first glance until I saw the second looping which make me confused why would it sorting from behind as well. Could anyone tell me if it's Bubble Sort or another sorting? Thank you in advance! |
| Infinty loop in constuctor - Creating the same istances of related objects Posted: 25 Nov 2021 07:46 PM PST I got stuck in an endless loop creating the same objects over and over in the models. But from the beginning: I have two related models, lets call A and B A could has many B and B belongs to one A.
And since model B refers to the fields of A, I added it as protected property to avoid creating new object when calling B method related with A fields. The constuctor of B looks like: public function __construct(int $id = null) { parent::__construct($id); $a = $this->get('a_id'); if ($a) { $this->a = new A($a); } }
and A: public function __construct(int $id = null) { parent::__construct($id); $this->date = new CarbonPL($this->get('date')); $this->initB(); }
But then I realized that calling initB() creates again the same instance o B with creating the same A and so on forever private function initB() { if (!$this->isReferenced()) { // Checks wheter is instance exists in DB return; } $query = B::getIDQuery(); $query .= ' WHERE is_del IS FALSE'; $query .= ' AND a_id = ' . $this->id; $ids = Helper::queryIds($query); foreach ($ids as $id) { $this->B[] = new B($id); } }
I need that object of A contains loaded of B and vice verse, because a lot of B refer to A field and vice versa, but how to prevent yourself from such an endless loop. I quickly got the idea of an extra parameter in B which would be A, and if it were, I wouldn't have to reuse the constuctor. But I don't really like this solution because of the second parameter and I was wondering how to solve it in a different (better) way, preferably so that you can still only enter the identifier. B conctructor after that fix:
public function __construct(int $id = null, A $a = null) { parent::__construct($id); if ($a) { $this->a = $a; } else { $a = $this->geti('a_id'); if ($a) { $this->a = new A($a); } } }

ive tried making sure its an integer and so on, just keep getting stuck on done? 1 for yes 2 for no, it always loop me back to type in guest while using structured text i often used this way of going back and forth, but i cant seem to understand it in python, maybe i should rather use case/switch? anyways if anyone could help me understand if you can use the IF statement this way in python is highly appreciated |
| Chain functions with callbacks TypeScript Posted: 25 Nov 2021 07:44 PM PST After reading an article about Handling Failure by Vladimir Khorikov, I try to implement it using TypeScript. The example code was written in C#, which I can understand only the idea, not the code. Here is my implementation so far. export class Result<T> { success: boolean; private error: string | null; private _value: T; get value(): T { if (!this.success) { throw new Error('Cannot get value of an error result.'); } return this._value; } get errorMessage(): string { if (this.success || this.error === null) { throw new Error('Cannot get error message of a success result.'); } return this.error; } get failure(): boolean { return !this.success; } private constructor(success: boolean, error: string | null, value?: T) { if (success && error != null) { throw new Error('Success result cannot have error message'); } if (!success && (error === null || error.length === 0)) { throw new Error('Failed result must have error message'); } this.success = success; this.error = error; this._value = value as T; } /** * Create failure result * @param errorMessage error message * @returns failureResult */ static fail<T>(errorMessage: string): Result<T> { return new Result(false, errorMessage); } /** * Create success result * @param value * @returns successResult */ static ok<T>(value?: T): Result<T> { return new Result(true, null, value); } /** * Combine multiple results into one result * @param results * @returns result */ static combine(...results: Result<any>[]): Result<any> { for (let result of results) { if (result.failure) { return result; } } return Result.ok(); } /** * Do things on success result * @param func * @returns result */ onSuccess(func: Function): Result<T> { if (this.success) { func(); } return this; } /** * Do things on failure result * @param func * @returns result */ onFailure(func: Function): Result<T> { if (this.failure) { func(); } return this; } /** * Do things on both success and failure result * @param func * @returns result */ onBoth(func: Function): Result<T> { func(); return this; } }
I am struggling to implement the chain functions. In the example code, the onSuccess, onFailure, and onBoth functions are chained beautifully. return Result.Combine(billingInfoResult, customerNameResult) .OnSuccess(() => _paymentGateway.ChargeCommission(billingInfoResult.Value)) .OnSuccess(() => new Customer(customerNameResult.Value)) .OnSuccess( customer => _repository.Save(customer) .OnFailure(() => _paymentGateway.RollbackLastTransaction()) ) .OnSuccess(() => _emailSender.SendGreetings(customerNameResult.Value)) .OnBoth(result => Log(result)) .OnBoth(result => CreateResponseMessage(result));
But in my code, it can only trigger void function. The function can't pass its result to the next function. Could you show me how to implement this? Any suggestions would be appreciated. |

for a class signature/constructor. The superclass constructor takes no parameters. Here is its signature/constructor: public class LinearProbingHT<Key, Value> implements SymbolTable<Key, Value> { protected int M; private int N; protected Entry[] keys; public LinearProbingHT() { M = 997; N = 0; keys = new Entry[M]; for (int i = 0; i < M; i++) { keys[i] = null; } } public int hash(Key k) { int retval = k.hashCode() & 0x7fffffff % M; return retval; }
Here's how I'm testing in Main: import java.util.Arrays;import java.util.HashSet;import java.util.Set; public class Main { public static void main(String[] args) { testIntegers(new QuadProbingHT<Integer, Integer>());} public static void testIntegers(SymbolTable<Integer, Integer> st) {}}
which gives me an error: Main.QuadProbingHT does not take parameters It seems like this constructor is not supposed to take parameters. Generics and for the most part inheritance are new to me, but I've tried playing around with the < > symbols in the signature, in the super, and nothing seems to be working. Is there a reason why it seems to be expecting parameters when the superclass constructor takes no parameters? Here's the entire QuadProbingHT class: public class QuadProbingHT<Key, Value> extends LinearProbingHT<Key, Value> implements SymbolTable<Key, Value> { public QuadProbingHT() { super(); } @Override public int hash(Key k) { int retval = k.hashCode() & 0x7fffffff % M; if (keys[retval] != null) { //collision alert int i = 1; while (keys[k.hashCode() & 0x7fffffff % M + i * i] != null) {//collision alert i++; } } return retval; }
} Symbol table interface: public interface SymbolTable<Key, Value> { // put key-value pair into the table void put(Key key, Value val); //get value paired with key Value get(Key key); //remove key (and its value) from table void delete(Key key); //is there a value paired with key? boolean contains(Key key); //is the table empty? boolean isEmpty(); //number of key-value pairs int size(); //all keys in the table Iterable<Key> keys();

| How'd i loop through every string.gmatch in a string then replacing the matches with a bytecoded version of that? Posted: 25 Nov 2021 07:47 PM PST How'd I change everything that it matches in the string without changing the non matches? local a = "\" Hello World! I want to replace this with a bytecoded version of this!\" but not this!" for i in string.gmatch(a, "\".*\"") do print(i) end
For example I want "\"Hello World!\" Don't Replace this!" to "\"\72\101\108\108\111\32\87\111\114\108\100\33\" Don't Replace this!" |
| express.js app knex.js async connection with aws secrets manager call is firing out of order Posted: 25 Nov 2021 07:44 PM PST I've been stuck on this for days, it feels like no matter how I structure it, the aws secret manager call ALWAYS returns after the app gets initialized. npm run start fires app.js file, this triggers knex and everything runs in order but the secrets response with the username/password seems to come back after everything's already initialized. knex.js: console.log("knex.js") const environment = process.env.APP_ENV || 'development' const config = require('../knexfile.js')[environment]; const knex = require('knex')(config); module.exports = knex
knexfile.js: require('dotenv').config(); const path = require('path') const pathToCert = path.resolve(__dirname, 'root.cert'); // where to save a file console.log("knexfile.js") var AWS = require('aws-sdk'); region = 'us-east-2' secretName = 'blah' var client = new AWS.SecretsManager({ region: region }); async function getConfig() { console.log("in get config") return await new Promise((resolve, reject) => { client.getSecretValue({ SecretId: secretName }, function ( err, data ) { let secret = JSON.parse(data.SecretString); console.log("returning it***************" + secret.password + " " + secret.username + " " + pathToCert) let connectionString = `postgresql://${secret.username}:${secret.password}@some-host:1234/defaultdb?sslmode=verify-full&sslrootcert=${pathToCert}&options=--cluster` resolve(connectionString) return }) }) } const config = { development: { client: 'pg', version: 7.2, connection: getConfig(), migrations: { directory: './knex/migrations', }, seeds: { directory: './knex/seeds' } } } console.log("exporting module") module.exports = config
The console returns: knex.js knexfile.js in get config exporting module Listening on: 3000 returning it***************pass username C:\project-webservice\root.cert

| Groupby year-month and find top K columns with target having smallest absolute values in the last day of each month using Python Posted: 25 Nov 2021 07:47 PM PST With sample data and code below, I'm trying to groupby year-month and find top K columns having smallest absolute values with target columns in the end of each month: import pandas as pd import numpy as np from statistics import stdev np.random.seed(2021) dates = pd.date_range('20130226', periods=90) df = pd.DataFrame(np.random.uniform(0, 10, size=(90, 6)), index=dates, columns=['A_values', 'B_values', 'C_values', 'D_values', 'E_values', 'target']) k = 3 # set k as 3 value_cols = df.columns[df.columns.str.endswith('_values')]
For example, if we set k=3, then for February 2013, we find A_values, B_values and E_values having smallest abs values with target, then using them as abs_1, abs_2 and abs_3 for this month. Same logic for other year-month. For rows which have on data for last day of month, then results for that month will be NaNs since we only take last day's data to calculate abs() values. My trial code, but it does not calculate the abs values of last day of each month. Also it raises an error: TypeError: nsmallest() missing 1 required positional argument: 'columns'. def calculate_abs(x1, x2): x2 = np.array(x2) res = np.mean(np.abs(x1 - x2), axis=0) # Here I use mean for each month, but I only need to take last day # print(res) return res def find_topK_smallest_abs(group): abss = calculate_abs(group[value_cols], group[['target']]) print(abss) cols = abss.nsmallest(k).index out_cols = [f'abs_{i+1}' for i in range(k)] rv = group.loc[:, cols] rv.columns = out_cols return rv df.groupby(pd.Grouper(freq='M')).apply(find_topK_smallest_abs)
How could I achieve that correctly? Should I use resample('M')? Sincere thanks at advance. EDIT: to filter last day of each month: df.loc[df.groupby(df.index.to_period('M')).apply(lambda x: x.index.max())]
Out: A_values B_values C_values D_values E_values target 2013-02-28 9.623960 6.165574 0.866300 5.612724 6.165247 9.638430 2013-03-31 2.717608 6.296843 0.087207 1.681396 4.635223 9.347712 2013-04-30 1.849324 2.510323 4.442528 1.106902 2.794064 5.927628 2013-05-26 4.930571 2.338785 9.823048 6.893207 6.312104 5.273122

I've seen quite old discussions of object cloning that suggest that the problem is quite complicated, but with ES6 a very simple solution presents itself - I will put it below and see if people think it is satisfactory. edit: it is being suggested that my question is a duplicate; I saw that answer but it is 7 years old and involves very complicated answers using pre-ES6 js.

| Status bar is back (visible) when controls of videoplayer in fullscreen are shown (visible) Posted: 25 Nov 2021 07:47 PM PST I use WebView for loading a video. I overrided onShowCustomView (to go to fullscreen) and onHideCustomView (to get out of fullscreen) methods. When I go to fullscreen mode a variable fullscreen is set to true and OnSystemUiVisibilityChangeListener calls GoFullscreen() function that sets SYSTEM_UI_FLAG_FULLSCREEN flag and also hides Action Bar: decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN); getSupportActionBar().hide();
But when I go to fullscreen mode status bar is visible if video controls are visible. So status bar hides only if video controls are gone (not visible). Screenshots to see a problem with controls of video and statusbar: ------------normal (ok) 
-----fullscreen with video controls (not ok) -------- fullscreen without video controls (ok)   Code: public class TestActivity extends AppCompatActivity { private MyWebChromeClient mWebChromeClient = null; private View mCustomView; private LinearLayout mContentView; private FrameLayout mCustomViewContainer; private WebChromeClient.CustomViewCallback mCustomViewCallback; private Bundle webViewBundle; private WebView mWebView; private int viewWidth; private int viewHeight; private LinearLayout.LayoutParams layoutParams; private View decorView; private Boolean Fullscreen = false; private void GoFullscreen() { decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN); getSupportActionBar().hide(); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); decorView = getWindow().getDecorView(); decorView.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() { @Override public void onSystemUiVisibilityChange(int visibility) { if (Fullscreen) { GoFullscreen(); } else { decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); getSupportActionBar().show(); } } }); mWebView = (WebView) findViewById(R.id.webView); mWebView.setBackgroundColor(Color.BLACK); mWebChromeClient = new MyWebChromeClient(); mWebView.setWebChromeClient(mWebChromeClient); mWebView.setWebViewClient(new WebViewClient(){ @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { return false; } }); WebSettings webSettings = mWebView.getSettings(); webSettings.setJavaScriptEnabled(true); viewWidth = 480; viewHeight = (int) (((double) viewWidth) * 0.5625); // video aspect 16:9 layoutParams = new LinearLayout.LayoutParams(viewWidth, viewHeight); mWebView.setLayoutParams(layoutParams); if (webViewBundle != null) { mWebView.restoreState(webViewBundle); } else { mWebView.loadUrl("http://vk.com/video_ext.php?oid=-89326201&id=171643607&hash=2b18b090e13222dc&hd=1"); } } @Override public void onPause() { super.onPause(); webViewBundle = new Bundle(); mWebView.saveState(webViewBundle); mWebView.onPause(); } @Override public void onResume() { super.onResume(); mWebView.onResume(); } @Override public void onDestroy() { super.onDestroy(); mWebView.destroy(); } public class MyWebChromeClient extends WebChromeClient { @Override public void onShowCustomView(View view, CustomViewCallback callback) { // if a view already exists then immediately terminate the new one if (mCustomView != null) { callback.onCustomViewHidden(); return; } Fullscreen = true; FrameLayout.LayoutParams LayoutParameters = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT); mContentView = (LinearLayout) findViewById(R.id.activity_main); mCustomViewContainer = new FrameLayout(TestActivity.this); mCustomViewContainer.setLayoutParams(LayoutParameters); mCustomViewContainer.setBackgroundResource(android.R.color.black); view.setLayoutParams(LayoutParameters); mCustomViewContainer.addView(view); mCustomView = view; mCustomViewCallback = callback; mContentView.setVisibility(View.GONE); GoFullscreen(); mCustomViewContainer.setVisibility(View.VISIBLE); setContentView(mCustomViewContainer); } @Override public void onHideCustomView() { if (mCustomView != null) { // Hide the custom view. mCustomView.setVisibility(View.GONE); // Remove the custom view from its container. mCustomViewContainer.removeView(mCustomView); mCustomView = null; mCustomViewContainer.setVisibility(View.GONE); mCustomViewContainer = null; mCustomViewCallback.onCustomViewHidden(); // Show the content view.
