MaxListenersExceededWarning: Possible EventEmitter memory leak detected.

I am developing a telegram bot following the tutorial and the code is working as I want. But there is a warning.

MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 close listeners added to [TLSSocket]. Use emitter.setMaxListeners() to increase limit

I found a solution via stackoverflow.

require('events').EventEmitter.defaultMaxListeners = 15;

I understand that removing the restriction will remove the warning, but not the cause, and you will not receive any alerts about the cause of the resource leak. But I can’t know the reason in my code.
This is my code:

const { Bot, InlineKeyboard } = require("grammy");

// Create a bot using the Telegram token
const bot = new Bot(process.env.HTTP_API_TOKEN || "");

const introductionMessage = `Hello! Welcome to Bot`;

const aboutUrlKeyboard = new InlineKeyboard();

const replyWithIntro = (ctx) =>
ctx.reply(introductionMessage, {
reply_markup: aboutUrlKeyboard,
parse_mode: "HTML",

// Keep this at the bottom of the file
bot.command("start", replyWithIntro);
bot.command("help", replyWithIntro);
bot.on("message", replyWithIntro);


Page Break issue in laravel

I’m encountering a problem with page breaks while printing an HTML document using a printDiv() function triggered by a button. The content overlaps or doesn’t break correctly between sections, causing formatting issues.

I’ve tried adjusting margins and page size using CSS @page rules, but the issue persists. Here’s the snippet I used for adjusting margins:

i am facing the issue. where i am not able to use page break in this code i am using laravel. can any one help me in this issue i am trying it for 3 to 5 days. Thanks.

What adjustments should I make to ensure that each section () in printableArea starts on a new page when printing? Are there specific CSS properties or print-specific adjustments I should consider to resolve this issue?

Extjs TagField dropdown items persistent after selection

I’m currenly trying edit TagField behaviour so that the dropdown items stay in dropdown even after you select one or multiple. Use case is something like revenue calculator (every user can determinate own math formula given some constants and math operators), so user can select f.e. symbol “+” multiple times to get formula they want. Is there a easier way then f.e. after selection add the record back to store? Is there better component for something like this?

As I described earlier I only tried TagField and not that pretty code after every selection. I bet there is better way to do it, I’m kidna new to Extjs. Thanks for every suggestion 🙂

Calculate the XYZ tile grid given an extent and resolution for a MapGuide server using OpenLayers

I’m trying to add a tiled map from MapGuide to my OL map. However, with my current code, the X and Y values in the request call are incorrect. I have tried specifying the tile grid with resolutions and extents, but it seems to have no effect. I have also considered using WMTS with a WMTS grid, but given the structure of the call I need to make, it doesn’t seem to be supported. How can I transform the tileCoord that Open Layers is generating to the ones I need to request?

This is my current code:

import Map from 'ol/Map.js';
import TileLayer from 'ol/layer/Tile.js';
import View from 'ol/View.js';
import {getTopLeft} from 'ol/extent.js';
import proj4 from 'proj4';
import { register } from 'ol/proj/proj4';
import OSM from 'ol/source/OSM';
import TileGrid from 'ol/tilegrid/TileGrid.js';
import XYZ from 'ol/source/XYZ.js'; 
proj4.defs('EPSG:25831', '+proj=utm +zone=31 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs');

// Define projection extent
var projectionExtent = [494035.69730822, 4676149.38116713, 502474.0732031, 4682213.46977595]; 
var resolutions = [
  50000, 40000, 30000, 25000, 20000, 17500, 15000, 12000, 10000, 9000, 8000,
  7000, 6000, 5000, 4500, 4000, 3500, 3000, 2500, 2000, 1500, 1000, 900, 800,
  700, 600, 550, 500, 450, 400, 350, 300, 250, 200, 150, 100

// Function to build custom tile URL
function buildTileURL() {
  let url
  url=' ...  other parameters .... &version=1.2.0&tilecol={x}&tilerow={y}&scaleindex={z}';  // Assuming scaleindex corresponds to the zoom level
  return url

// XYZ source with custom URL function
var mapGuideSource = new XYZ({
  tileUrlFunction: function(tileCoord) {
    if (tileCoord) {
      return buildTileURL()
        .replace('{x}', tileCoord[1].toString())
        .replace('{y}', tileCoord[2].toString())
        .replace('{z}', tileCoord[0].toString());
    return undefined;
  projection: 'EPSG:25831',

const tileGrid = new TileGrid({
  extent: projectionExtent,
  resolutions: resolutions,
  tileSize: [300, 300],
  origin: getTopLeft(projectionExtent)

// Create the map layer
var mapGuideLayer = new TileLayer({
  source: mapGuideSource,
  tileGrid: tileGrid,
  extent: projectionExtent,

export const osmLayer = new TileLayer({
  source: new OSM(),

// Create the map
var map = new Map({
  target: 'map',
  layers: [mapGuideLayer,osmLayer],
  view: new View({
    projection: 'EPSG:25831',
    center: [498254.88525566, 4679681.39547154],

Accessing a dynamic Google Earth URL via JavaScript with some certain coordinates, but it actually sends me to the previous saved location

I’m trying to access a dynamic Google Earth URL via JavaScript which works great, but I have only one problem. By doing so, after a while, because of the cookies that are saved on that page it seems that it won’t get me to where it is supposed to get me, and it sends me to the previous saved location from cookies, because after I clear the cookies from Google Earth manually, it works. I don’t want to clear them manually every time, because this is for an app with users. I want to solve this problem from JavaScript code.

Code snippet:`${coords[0]},+${coords[1]}/@${coords[0]},${coords[1]},196.55454222a,112.74878798d,35y,0h,0t,0r`, '_blank');

How to Smoothly Animate a Conic Gradient Background in CSS?

I’m trying to create a smooth animation effect for a conic gradient background in CSS. My goal is to have the gradient appear to shift smoothly without rotating the entire element.

Here’s the CSS I’m currently using:

body {
    width: 100%;
    height: 100vh;
    display: grid;
    place-items: center;
    overflow: hidden;
    margin: 0;
    position: relative;
    background: conic-gradient(from 0deg, #d5d06a, #be6d11);
    animation: animateGradient 10s linear infinite;

@keyframes animateGradient {
    0% {
        background: conic-gradient(from 0deg, #d5d06a, #be6d11);
    25% {
        background: conic-gradient(from 90deg, #d5d06a, #be6d11);
    50% {
        background: conic-gradient(from 180deg, #d5d06a, #be6d11);
    75% {
        background: conic-gradient(from 270deg, #d5d06a, #be6d11);
    100% {
        background: conic-gradient(from 360deg, #d5d06a, #be6d11);

However, the animation doesn’t look smooth—it appears to be jerky and not continuous. I’m aiming for a seamless and fluid transition.

My questions are:

  1. How can I achieve a smooth, continuous shifting animation for a conic gradient background?
  2. Are there better techniques or optimizations to animate conic gradients in CSS for a more fluid result?

I initially tried animating the background property with keyframes to create a shifting effect in the conic gradient. My expectation was a smooth, seamless animation where the gradient would appear to flow continuously. However, the result was a jerky and non-fluid transition. I also experimented with using CSS variables to adjust the starting angle dynamically and tried rotating a pseudo-element, but neither approach yielded the desired smoothness. I’m looking for a method to make this animation as smooth and continuous as possible.

How to ensure that some code or module runs before any other module?

In a React app, I’m defining an extension on the Object class itself:

declare global
    interface Object
        asEnum<TEnum>(this: TEnum): EnumWrapper<TEnum, any>;

export function extendObjectType()
    Object.prototype.asEnum = function()
        return new EnumWrapper(this as any)

(I am aware that extending Object in this way is controversial, but I understand the issues, I’m comfortable with this, and as far as I can tell it’s unrelated to my problem.)

EnumWrappper is a custom class (not shown) that does useful things with the object that represents the enum that it’s wrapping.

Then I can do this:

enum YesNoMaybe

console.log(YesNoMaybe.asEnum().keys.join(","))  //prints out "Yes,No,Maybe"

This actually works and does print out the desired value, but obviously only if it runs after the code that extends the Object class. This is true in my React components, but not in a module in general, because the module code seems to run before the extension is made.

I have tried many things to arrange it so that the extension runs first, such as:

  • putting it in the main.tsx component
  • adding a custom script in the React loader html
  • making it the first module alphabetically

None of this helps. So the general question is: how can I arrange things so that a given block of code (or module) runs before any other module?

How to split bigint into 32 bit chunks and recombine them?

How do I split a large bigint into a 32 bit number array? I also need to recombine them to the bigint again.

I have an api that takes an array of max 32 bit integers and returns an array of max 32 bit integers. But I have a large bigint number that I need to pass into and receive back from this api.

How do I do the splitting and recombining?

Don’t report a fetch timeout as an uncaught exception

I use:

fetch("/test", { signal: AbortSignal.timeout(2000) })
    .then(r => r.json())
    .then(r => { console.log(r["data"]) });

with the method from Fetch API request timeout? to abort the request after 2 seconds if no response.

In the case of a timeout, I have a JS error in the console:

Uncaught (in promise) DOMException: The operation timed out.

What’s the simplest way to avoid having this reported as an error?

I would like the timeouts to be silently ignored.

Trouble Interacting with Dropdown FormField in PHPWord

I’m using PHPWord to create a Word document with an interactive dropdown form field. Below is a snippet of my code:

$cell = $table->addCell();
$textRun = $cell->addTextRun();
$textRun->addFormField('dropdown')->setEntries(['Choice 1', 'Choice 2', 'Choice 3'])->setValue(1);

However, when the Word document is opened, the dropdown displays the selected value (“Choice 2”) but does not allow me to change the selected option interactively.

I want to create a dropdown like this:
enter image description here

But the result not my expected. I Can’t change the option and there isn’t any dropdown arrow. I can see the other options when I double click on the field and they appear to be editable (Can add, remove and change sequence). And when I click “OK” to close the popup, the selected option always changes to the first of option (“Choice 1” in this case).
enter image description here

Has anyone else encountered this issue or have any suggestions on what may be causing this and how to fix it? Any help or pointers would be greatly appreciated!

Thanks in advance!
