I have two perpendicular rectangles in an "L" shape and I'm trying to pivot the vertical one towards the other (the corner of the L should be the pivot point) but I'm running into two issues: the vertical one begins to skew into a parallelogram and also it seems to lose some height as it rotates around. Can you help me figure out what I can change to fix this? :root { --vdilation_factor: 2; --vdilation_factor_inv: calc(1 / var(--vdilation_factor)); /* Compute the inverse of dilation_factor */ --hdilation_factor: 10; --hdilation_factor_inv: calc(1 / var(--hdilation_factor)); /* Compute the inverse of dilation_factor */ } .container { position: relative; height: 400px; /* Increased height to accommodate animati

I built a simple user administration app in JavaScript/React. It covers the basics, listing users, adding, editing, and deleting them, but I feel like there's a lot of room for improvement and I'm not sure where to focus next. Here is my App.jsx import { useState } from 'react' import './App.css' import { Users } from './components/Users' import { createUser, deleteUser, getUsers } from './services/user.service' import { UserEdit } from './components/UserEdit' function App() { const [users, setUsers] = useState(getUsers()) const handleNewUser = (user) => { createUser(user) setUsers(getUsers()) } const handleDeleteUser = (user)=> { deleteUser(user) setUsers(getUsers()) } return ( <> <h2><i className="bi-person text-primary me-2"></i>User-Administration</h2> <div className="card"> <h4>New User</h4> <UserEdit onNewUser={handl

I have a JSON string and I want to: Validate if it's correct JSON Format (pretty-print) it for better readability What is the best way to do this in JavaScript? Answer: You can validate and pretty-print JSON in JavaScript using built-in methods like JSON.parse() and JSON.stringify().

g++ .\test_sort.cpp -O3 -march=native -mtune=native -flto -funroll-loops -fomit-frame-pointer -DNDEBUG C++: 8577.17 ms ------------------------------- rustc -C opt-level=3 main.rs Rust: 1379.375 ms I noticed that Rust’s sorting functions, especially sort_unstable, often seem significantly faster than C++’s std::sort in benchmarks. I understand that Rust’s sort_unstable is based on ipnsort (previously pdqsort-related work), while C++ implementations of std::sort are typically introsort-based depending on the standard library implementation. What specifically makes Rust’s implementation faster in practice? Is it mainly due to algorithmic differences (ipnsort vs introsort)? Is it because Rust specializes more aggressively for primitive types? Does branch prediction, partitioning strategy, or handli

I m trying to upload videos automatically to cloudinary using chokidar but it's is not uploading the videos to the cloudinary although the code is correct. Suggest me some code so that i can use the code properly and upload the videos to the cloudinary

It is possible to design non-constructible classes, but I managed to instantiate an object of such a class: #include <bit> #include <cstring> #include <iostream> // Not constructible // Not implicit lifetime struct Test { int val{1}; Test() = delete; Test(Test const&) = delete; Test(Test&&) = delete; Test& operator=(Test const&) = default; Test& operator=(Test&&) = default; ~Test() = default; operator int() { return val; } }; int main() { char storage[sizeof(Test)]; int i{666}; std::memcpy(storage,&i,sizeof(Test)); auto HeWhoMustNotBeNamed = std::bit_cast<Test>(storage); std::cout << HeWhoMustNotBeNamed.val; } LIVE All tested compilers (gcc, clang and msvc) recognize Test as trivially copyable.

I am looking for best practices on how to implement horizontal architecture with the latest Spring gRPC [1] in Kubernetes. In my Kubernetes cluster, I have one main service, which connects to multiple so-called worker services via gRPC and a load-balancer. However, when executing a simple for-loop to send requests to the workers, only a single one of those receives the requests. I am asking speficially, because to my understanding, a gRPC channel might contain multiple connections (sub-channels), but our Kubernetes cluster distributes requests to other pods according to channels, not simply connections (sub-channels) therein, i.e., L4 balancing, confer gRPC Load Balancing. Thus, do I need to setup a pool of gRPC channels [2] manually, as described in a very recent article here:

I'm building a web application that has ~34 independent dropdown lists (e.g. currency codes, country names, user types, example statuses, etc.). Each list has no relation to the others — they're purely used to populate <select> elements in forms. Which approach is standard for admin-managed dropdown lists? Would it be good to create a single table that have all this options or what.

I need to be notified when an object is added or removed from an list and also when one of the objects in it is modified: var myList = [1, 2, 3]; myList.add(4); -> need a notification myList[1] = 0; -> need a notification var myVar = myList[2]; myVar = 3; -> need a notification I'm trying to figure out if it's possible to avoid installing third-party components, such as: https://flutter-it.dev/documentation/listen_it/collections/list_notifier or avoid writing dedicated methods, such as: void addItem(int number) { myList
