I am working on a WPF application where I need to implement a document generation and printing feature. My Goal: I have dynamically generated HTML content (with CSS). I need to: Convert this HTML content into a PDF document. Ensure the output is strictly formatted to fit an A4 sheet (handling page breaks, margins, etc.). Send this generated PDF directly to a printer. My Question: What is the most reliable, industry-standard approach to achieve this in a modern WPF application? I am looking for recommendations on the best libraries or built-in approaches to use. Specifically, I’d love to know: Which libraries are best suited for this (e.g., WebView2, PuppeteerSharp, wkhtmltopdf, iText7, QuestPDF)? Are there any caveats I should watch out for regarding CS

Problem I'm building a monorepo that has both a Next.js App Router app and a Remix v2 app. I need to manage SEO meta tags (title, description, Open Graph, Twitter Card, robots directives like maxSnippet, maxImagePreview, canonical URL) across both apps. Right now I'm maintaining two separate implementations: Next.js (app/blog/[slug]/page.tsx): export async function generateMetadata({ params }) { const post = await getPost(params.slug); return { title: post.title, description: post.excerpt, robots: { index: true, follow: true, }, openGraph: { images: [{ url: post.coverImage, width: 1200, height: 630 }], }, }; } Remix v2 (app/routes/blog.$slug.tsx): export const meta: MetaFunction = ({ data }) => { return [ { title: data.post.title }, { name: 'description', content: data.pos

Using LiveServer in VS Code, I have setup an html page that I can access from any device on my LAN. On this app I have it set to store and read data using localStorage in javascript(typescript is what I type in). Where would I go from here in order to have the stored data be accessible from anyone accessing that page from anywhere in the LAN? I presume I will have to learn something entirely different(like express, one of the pages I found that vaguely mentioned but had no detail as to the how?), but I have no idea what direction to go in to learn how to do this specific thing, and wanted to see if anyone had suggestions for how to proceed.

I'm trying to a framework to share webp files for Android and heic files for iOS for the same name of images? For example, I have a file called home . So we will have home.webp for Android and home.heic for iOS. I know we can just put the webp in androidMain/res/drawable-{density}/home.webp for Android. And call it like this: /// Common Main expect class PlatformImage class ImageAsset( val name: String ) { @Composable fun toImage(): PlatformImage? = getPlatformImage() override fun toString(): String = name } @Composable internal expect fun ImageAsset.getPlatformImage(): PlatformImage? /// Android Main /// Should manually copy the assets to `androidMain/res/drawable-{density}/` first actual typealias PlatformImage = Painter @Composable internal actual fun ImageAsset.getPlatformImage(): PlatformImage? { Resources resources = context.getResources(); final int resourceId = resources.getIdentifier(nam

What is the difference between setTimeout and setInterval? When can each be used? is it a good practice to use both interchangeably since both can be used to time-related effects?

I am developing a Spring Boot 3 application (Java 25) that periodically checks for updates from external APIs (GitHub/StackOverflow). I have two repository implementations: one using JdbcTemplate (SQL) and another using EntityManager (JPA/ORM). The application uses a fixed thread pool to process links in parallel. The Problem: When I use the SQL implementation, everything works perfectly. However, when I switch to the JPA implementation, I consistently get the following error during parallel execution: A problem occurred in the SQL executor : Error advancing (next) ResultSet position [This ResultSet is closed.] My JPA Repository method: Java @Override public OffsetDateTime getUpdatedAtByUrl(String url) { String query = "select l.lastUpdatedAt from Link l where l.url = :url"; return entityManager

I suppose this is kind of a strange question, but I want to "uncollapse" a row of data in R, as follows. The original data is, for example, a data frame row where v1 = 1, v2 = 2, as here: collapsed = structure(list(v1 = 1L, v2 = 2L, v3 = 3L, v4 = 4L, v5 = 5L), class = "data.frame", row.names = c(NA, -1L)) I want the end result to look like this: uncollapsed = structure(list(v1 = c(1L, 1L, 1L, 1L, 1L), v2 = c(NA, 2L, 2L, 2L, 2L), v3 = c(NA, NA, 3L, 3L, 3L), v4 = c(NA, NA, NA, 4L, 4L ), v5 = c(NA, NA, NA, NA, 5L)), class = "data.frame", row.names = c(NA, -5L)) There are packages like collapse and tidyr that provide functions for collapsing data, but I can't find functions that do the opposite. I am running a loop right now to create the "uncollapsed" data frame. I'm wondering if there are better ways to do this, since my real workflow involves billions of rows of data.

Im working on an app for australian government under a private company. The app will be used by a specific department of the australian government and it'll be available on ios. The confusion i have is this the app is private-use only and will not be for public but in order to be on ios it must be on appstore connect. Currently, I'm putting it on internal testing where through testflight the department officers can use it and test it but when it final what should be the proper way of delivering the app. Should i keep it on internal testing as it works fine on it and update a version before every 90 days or should I apply it for review but that'll be for public too and that is strictly not the requirement. How to deploy such app and if alternative then what?
