AI aside, Golden Gate includes a bunch of subtle-but-helpful improvements.
A lot of discussion about Fable 5 has focused on the visible restrictions: cybersecurity, biology, certain chemistry. You hit a wall, you get a notification, you get redirected to Opus 4.8. That's frustrating, but at least it's honest. At least you know the model stepped back. Here's the part that's really disturbing, buried in a 319-page system card: There's a second category of restriction. For AI development and research work, Fable 5 doesn't redirect you. It doesn't notify you. It responds. It just delivers a deliberately weakened answer, and the system card describes this explicitly as "not visible to the user." Anthropic walked this back within 24 hours after fierce backlash. They apologized. "We made the wrong tradeoff." Good. But sit with what actually happened here, because the reversal is being treated as the end of the story when it's the beginning of a much harder problem. We now know three things we cannot unknow: Anthropic built this. They shipped it. And they only reversed it when the backlash was loud enough. The question isn't whether this specific invisible downgrade still exists. The question is what else might they be doing, in categories that don't generate the same backlash, that isn't disclosed in a document most people will never read anyway. This is a new kind of problem. And to understand why, you have to take a step back for a second. The pattern In January 2026, OpenAI announced that they would retire GPT-4o. Hundreds of thousands of daily users had built working relationships with that model over months: preferences it learned, corrections they made, communication styles that developed through hundreds of sessions. Gone. In February 2026, Gemini users found their chat histories had quietly vanished. No warning. No export. In April, Anthropic cut off Claude Pro and Max subscribers from using their subscriptions with third-party tools. Workflows that people depended on broke overnight. Each of these was framed differently. Model retirement
I set up a Claude CLI instance on a Google Cloud VM Instance, cloned all my project repos (we run a dev agency), and wired up webhooks to Linear. When a ticket gets tagged, the CLI automatically reviews the relevant repo, understands what needs to be done, and drops a detailed technical breakdown right into the ticket. It's cut ticket completion time because devs now have way more context to feed into Claude Code or Cursor and just start building. Next step: I'm trying to get Claude to actually create working PRs based on that evaluation and knock out the whole ticket end-to-end. Still figuring out if the loop can fully close. Has anyone worked on a system like this? Would love to hear your approach. submitted by /u/theTbling [link] [留言]
Every layer of AI solved the problem the last one left behind. The unsolved one: a shared, measurable standard for how to RUN intelligence — yours and the AI's, together. I spent 10+ years writing it down and it's falsifiable (pre-registered tests, failure lines locked before data).

I think it is but I'd just like to get some second opinions, especially from music creators. This is their spotify page https://open.spotify.com/artist/4dSJvPjnA1RU6KcngvaZ96 The artwork is definitely AI and there's no real composer name so some red flags there already. submitted by /u/WelderRound2925 [link] [留言]

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.

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]
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.
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…
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. Toolbar APIs The toolbar has been a source of friction on smalle
Ask a large language model for a specific statistic, then ask where it found that number. More often than not, the citation it gives you doesn't exist. The model will hallucinate a plausible-looking reference, confidently present outdated conclusions, or simply make things up without any internal signal that something is wrong. This failure mode has a well-known name — hallucination — and the most widely adopted engineering solution for it is RAG. RAG in One Sentence RAG stands for Retrieval-Augmented Generation. The idea is straightforward: before the LLM generates an answer, retrieve relevant document chunks from an external knowledge base, then feed those chunks to the model as context so it can compose its response based on real source material rather than parametric memory alone. Think of it like writing a research paper. You don't cite statistics from memory; you look them up first, then write your argument around verified data. RAG gives language models the same "look it up, then write" workflow. Three Structural Limitations of LLMs To understand why RAG is necessary, we need to identify the specific gaps it fills. Knowledge cutoff. Every model has a training data deadline. GPT-4's cutoff is late 2023; Claude's is early 2025. Anything that happened after that deadline simply doesn't exist in the model's world. It will either admit ignorance or, more dangerously, fabricate an answer that sounds current. Bounded parametric capacity. Even a 100-billion-parameter model can only "memorize" so much. Long-tail facts, niche domain knowledge, your company's internal documentation, yesterday's meeting notes — none of these are in the weights. No built-in fact-checking. Token generation is probabilistic sampling. The model has no mechanism to distinguish whether it's recalling a training fact or pattern-matching its way into a plausible-sounding fiction. RAG addresses all three: it supplies up-to-date, verifiable, externally sourced evidence at inference time. How RAG W
