This impressively light carbon commuter makes switching to an ebike easier than ever.

The musician created his own line of loopers that record and layer riffs in a loop. The pricey Looper X does what it claims, but it isn’t without quirks.

It might not feel all that different from older World Cups—for better or worse.

Deezer will now help you find AI slop in your music playlists even if you're on another platform.

YouTube is reintroducing private messaging after testing new ways for users to share videos and "have conversations about them" last year. In an announcement on its official blog, YouTube says it's now starting to expand the in-app video sharing and messaging feature to users in the US and "other global regions" who are 18 or […]

as in the title, my goal is to predicting failure and RUL of machine, dataset is timestamp and when machine is failure it will labeled with 1 that only have 56 https://preview.redd.it/plbydmenmm6h1.png?width=1205&format=png&auto=webp&s=2fefe3cc2e3fe554b81c9e0b4012c5345e73ec3f From this data im ditching operating hours and humidity because it didnt show correlation for machine failure, what algorithm or deeplearning suit for it? submitted by /u/False-Seesaw-1899 [link] [留言]

The games start June 11 and end with a grand finale in New Jersey on July 19. There are 104 of them. Here’s how to watch ’em all.

Venues hosting the 2026 World Cup must meet high standards to obtain environmental certifications, but FIFA also requires that they use natural grass, which is water-intensive to maintain.

In 2018, after nearly two decades working in Big Pharma, chemist Tim Cernak was ready to put his skills to a new use. For Merck, he’d developed precision therapies for cancer, HIV, and diabetes that could target disease while minimizing harm to healthy cells. But as a lifelong nature lover, he was increasingly concerned about…

Imagine tuning in to the opening kickoff of a World Cup match and seeing a player intentionally send the ball all the way down the pitch and right out of bounds on the opponent’s end. Casual fans might scratch their heads. Where’s the logic in surrendering possession seconds into a game? If you were Jesse…

It’s a tale of two nuclear industries. In China, large reactors are coming together at a stunning pace. The country has nearly doubled its nuclear fleet since 2016, reaching nearly 60 gigawatts of total power capacity. The new facilities are nearly all gigawatt-scale pressurized-water reactors. Meanwhile, the US has built just two reactors in that…

Travel bans and other visa issues are creating problems for World Cup participants even before the whistle blows.

Soccer officials already rely on cameras to see who’s offside and who sent the ball out of bounds. But during this World Cup, refs will use digital twins of each player to view plays from every angle.

For years, whenever I needed to merge two PDFs or compress a file to upload to a government portal, I would Google "compress PDF", click the first result, and inevitably hit a paywall. "You have reached your 2 free files per day limit." Worse, I was uploading sensitive documents—tax returns, medical records, and NDAs—to random servers in God-knows-where just to strip out some heavy images. I decided to build an alternative. I wanted it to be 100% free, have absolutely no daily limits, and most importantly: zero server uploads . Here is how we built PDF Pro using Next.js and WebAssembly to process PDFs entirely natively inside the user's browser. The Architecture: Why WebAssembly? Traditional PDF tools (like Smallpdf or iLovePDF) use a monolithic server architecture. You upload your file to their AWS bucket, their backend runs a Python or C++ script (usually using Ghostscript or a proprietary library) to manipulate the PDF, and then you download the processed file. This architecture is expensive (high bandwidth and compute costs) and creates a massive privacy liability. By compiling a C++ PDF manipulation library down to WebAssembly (WASM) , we inverted the architecture. 1. The Build Process We took pdf-lib and custom C++ compression algorithms and compiled them to a lightweight .wasm binary. When a user visits PDF Pro Compress , their browser downloads the ~2MB WASM file once and caches it. 2. Client-Side Processing When you drag and drop a 50MB PDF into the UI, it never hits our server. Instead, the browser's JavaScript engine passes a Pointer to the file data directly into the WebAssembly memory buffer. The WASM module executes native C++ speeds directly on your local CPU to compress or merge the document. Performance Benchmarks Because there is zero upload and zero download time, the performance metrics are staggering: 10MB PDF Compression (Cloud): ~15 seconds (Upload) + 4 seconds (Process) + 5 seconds (Download) = 24 seconds . 10MB PDF Compression (PDF Pro WASM)

Most people studying for Security+ use practice questions the wrong way. They take a 90 question set, score a 74, feel bad, take another set the next day, score a 76, and call that progress. Two weeks later the number has barely moved and they have no idea why. The score is the least useful thing a practice exam gives you. What you actually want is a map of what you do not know yet. Here is the approach that worked for getting through SY0-701 without burning out on endless question sets. Start cold, on purpose Before you study a single domain, take a full practice exam and do not look anything up. It will feel bad. That is the point. A cold score tells you where you actually stand, not where your notes say you should be. SY0-701 is split into five domains, and they are not weighted evenly: 1.0 General Security Concepts (12%) 2.0 Threats, Vulnerabilities, and Mitigations (22%) 3.0 Security Architecture (18%) 4.0 Security Operations (28%) 5.0 Security Program Management and Oversight (20%) Domain 4 alone is more than a quarter of the exam. If you bomb Security Operations and ace General Concepts, splitting your time evenly between them is a mistake. A cold diagnostic shows you that split in about an hour. If you want one to start with, there is a free diagnostic exam at secplusmastery.com/diagnostic that breaks your result down by domain so the holes are easy to see. Review the wrong answers, and the right ones too This single habit moved my scores more than anything else: for every question I missed, I wrote down why each wrong option was wrong, not just why the correct one was correct. Security+ loves distractors that are real terms used in the wrong context. A question about a control that prevents an attack will offer you a control that detects one, and a control that corrects after the fact, all as plausible answers. If you only learn that the answer was C, you learn nothing you can reuse. If you learn that B was a detective control and the scenario asked for a p

You've built todo apps, counters, and forms. But can you handle a grid of 50 cells that reference each other through formulas? This challenge pushes your state management skills into real spreadsheet territory — formula evaluation, two-way cell bindings, and an interface that juggles editing, selection, and keyboard shortcuts all at once. 🔥 Start the Challenge Now 🧩 Overview Build a spreadsheet with real-time formula evaluation. You'll wire up a 10-row × 5-column grid where cells support basic values and Excel-style formulas (like =A1+B2), column and row selection, and a formula bar that mirrors what you're typing. ✅ Requirements Render a spreadsheet with column headers A through E and rows 1 through 10 Each cell uses an <output> element for the computed value and an <input> overlaid for editing Click a cell to edit; press Enter or blur to commit the change Formulas starting with = must be evaluated: Arithmetic: =1+1 → 2 Cell references: A1= 5 and B1= =A1+3 → 8 Click a column header to select/deselect that column Click a row number to select/deselect that row Selecting a column deselects any row and vice-versa Backspace clears the selected column or row Click outside the table deselects everything A formula bar ( fx ) mirrors the editing cell's value Cells must start empty — no default values 💡 Notes Use useState for cells, selected column, and selected row. No need for useReducer here. Each cell uses two overlapping layers: a visible <output> for the computed value and an invisible <input> for the raw formula. Toggle with opacity-0 / opacity-100 so the input stays mounted. Evaluate formulas with eval : generate JS const declarations from all cell values, wrap them in an IIFE, and evaluate. Recompute every cell on any change — cells can reference each other. 🧪 Tests renders the app title renders the spreadsheet with column headers A-E and rows 1-10 renders cells with initial empty values allows editing a cell and displays the new computed value evaluates a simple fo

WWDC26 brought a substantial round of updates to SwiftUI — not a ground-up redesign, but a lot of small limitations removed, new APIs that were clearly driven by real-world pain points, and meaningful performance improvements. This post walks through every major announcement so you know exactly what's available and when to reach for it. Look and Feel: Liquid Glass and the 2027 Releases The most immediately visible change costs you zero code. Apps built with SwiftUI automatically pick up the updated Liquid Glass appearance on the 2027 OS releases. The glass tint responds to the new system-level Liquid Glass slider without any changes on your part. On iPad, windows now dim when inactive, reinforcing which window has focus — again, automatic. On Mac, custom interactive Liquid Glass elements respond more fluidly to the mouse pointer. There are a few opt-in refinements available when you want tighter control: Responding to active state — use the appearsActive environment value to reduce opacity on custom elements when the window is inactive: struct SidebarFooterView : View { @Environment (\ . appearsActive ) private var appearsActive var body : some View { MyAccountView () . opacity ( appearsActive ? 1 : 0.5 ) } } Menu bar icons — the menu bar now shows a minimal set of icons by default. Add .labelStyle(.titleAndIcon) to a specific menu item to make its icon visible: CommandMenu ( "Stickers" ) { Button { openStore () } label : { Label ( "Store" , systemImage : "bag.fill" ) . labelStyle ( . titleAndIcon ) } } Resizability on iPhone iPhone apps become resizable on iOS 27, which matters for iPhone Mirroring and running iPhone apps on iPad. Xcode 27's Live Previews now include resize handles so you can test this interactively without running on a device. If your app mixes UIKit and SwiftUI, check the session "Modernize your UIKit app" for specifics around screen geometry, size classes, and orientation handling.
