I'm looking to improve the logic used in this ETL pipeline manager. The concept creates a structure: Pipeline(Pipe(Task, [Task, ...]), [Pipe(...), ...]) ...where a Pipeline contains one or more Pipes and a Pipe contains one or more Tasks. Another important concept is the Operators, namely the Han...

This post is the continuation of A simple, funny, easy linked stack of lists in Java. What's new: Now I have varargs for pushing/linking multiple values per call. Provided the unit tests. com.github.coderodde.util.Multistack.java: package com.github.coderodde.util; import java.util.ArrayList; ...

I'm primarily looking for perspectives about correctly using .NET to implement TLS over TCP. We develop a Java application that serves requests over TCP. We also develop client libraries for the application, where each library supports a different language/platform (Java, .NET, etc.). Recently we...

I am trying to merge multiple map with Java stream API. The reqiurements like ... support 2 merge method: intersection, union if key duplicates, it overwrites with later value Here is basic code I wrote, public class MapMergeHelper { public static Map<String, String> merge (MapMergeOperatio...

I am new to Rcpp and am looking to make the following code as fast as possible. Any tips would be greatly appreciated. It is running a lot slower than I would like. I have tried vectorising as much as possible but i'm not sure how to vectorise further // [[Rcpp::export]] arma::mat fn_update_log_...

I have a blazor webassembly project, which is protected using Azure AD. I don't like the idea of immediately forwarding a user to a login page without context, so I usually use <AuthorizeView> to display different content based on whether a user is authenticated or not. Now in order to make the c...

I have a "flat file" with structure as below: machineCode,Key,Ip_Name_No,Share_Percent,Account_Name,Account_No "ygh048GT",4767,534293748,"100.00","cderfgdsc Publishing International Ltd","160102040" "xcd064HW",6380,65424090,"100.00","dascdfrgh snm skion","00090382478" ...

I have the code such as this for opposite conditions. For Each iCell In Range("A2:A6").Cells If iCell.EntireRow.Range("H1").Value = "" Then BOM = InputBox("The current BoM Code is...", "BoM Calculator v1.1", (iCell.Value)) scrUpdt = Application.ScreenUpdating Applicati...

I have tried to implement my singly linked list to be optimal in the sense that when inserting I don't have to search for the tail and then chain the new node to it, I just keep track of the tail and then insert, resulting in O(1). This is my insert: #include <stdio.h> #include <stdlib.h> typed...

Can I get the below output without using any libraries? (in a shorter way) Input: items = [ {'product': 'A', 'customer': 'A', 'count': 10}, {'product': 'A', 'customer': 'B', 'count': 15}, {'product': 'A', 'customer': 'C', 'count': 100}, {'product': 'A', 'customer': 'A', 'count': 50}, ] O...

Let's compare these 2 short Java code snippets. Which version do you prefer? The 2nd is more concise for sure. However the second option gives a reader an extra information about what is the content of the data returned by the query function and the type of the intermediate list. I often find mys...

my question is about synchronisation and preventing deadlocks when using threads. I made up a simple class for demonstration purposes. public class Data { private long value; private Lock lock = new ReentrantLock(); public Data(long value) { this.value = value; } pub...

I am trying to improve my Rust coding skills. One thing which I find hard to tackle is how to shift from a polymorphism you can observe in e.g. Python to sth. similar in Rust? Let me give you a specific example. I would like to implement a very simple Graph (undirected graph) and DiGraph (directe...

I have a working gizmo movement script made in Raylib that allows me to move an entity (i.e. entity_in_inspector) in a 3D space using 6 arrows. Each arrow is rotated at a 90º degree angle from each other, and when I hover my mouse over an arrow, it turns green and I can change the entity's positi...

Given the following signature: /** * @param predicate an async function that if false will skip the callback, but will still poll. * @param asyncFunction the async function to call. (there's a high likelihood this will change the state) * @param options extra options for polling */ export fun...
