This flight will put Starship under higher pressure and test out new Starlink satellites in orbit.

I watched this video and I want to apply some code that I didn't understand in this way. Does anyone have any knowledge about this? submitted by /u/Every-Pitch2616 [link] [留言]

AudioTrust: reconciliar C2PA y watermark AudioSeal en audio sintético Un verificador local que lee las dos marcas de confianza de un audio generado por IA (procedencia C2PA + watermark AudioSeal) y emite un veredicto auditable sobre si coinciden, se contradicen o faltan. El problema Un audio sintético puede llevar dos marcas de confianza distintas: Procedencia C2PA : un certificado digital embebido en el archivo (su "DNI" de origen — quién, cuándo, con qué herramienta). Watermark AudioSeal : un código inaudible incrustado en el sonido, detectable aunque el audio se comparta o transcodifique. Cada una por separado es útil, pero ninguna es suficiente. La procedencia puede faltar (mucho audio generado no la incluye) y el watermark puede estar presente en audio totalmente legítimo. El caso interesante es cuando se contradicen : el manifest C2PA dice "grabado por un humano con una grabadora" pero el watermark de una herramienta de IA está presente. Eso es una señal de manipulación — el llamado Integrity Clash . AudioTrust no genera ni firma nada. Es un verificador : lee ambas capas y las reconcilia. Qué hace audio.wav ──► AudioTrust verify ──► veredicto + explicación C2PA watermark Veredicto ausente ausente unverifiable ausente presente partial origen sintético presente trusted origen humano presente contradiction (Integrity Clash) Salida JSON: { "file" : "audio.wav" , "verdict" : "trusted" , "c2pa" : { "present" : true , "source_type" : null , "claims" : [ "action=c2pa.created by TestTTS" , "generatedBy=TestTTS" ]}, "watermark" : { "present" : true , "detect_prob" : 0.92 }, "explanation" : "C2PA declara origen sintético y hay watermark fuerte: coherentes." } Cómo funciona Lectura C2PA con c2pa-python (el Reader de la librería oficial).

Here is a reliable test: find a prompt that isn't working. Read it carefully. Now ask yourself — at which specific sentence did the model get permission to do what it did wrong? You will almost always find it. A hedged instruction. A missing constraint. An ambiguous scope. The model did not misunderstand you — it followed the most statistically probable interpretation of what you wrote. That interpretation was not the one you intended. These are not beginner mistakes. They are structural patterns that reappear at every experience level, because they look reasonable when you write them and only reveal themselves in the output. TL;DR: Prompts fail because they hand interpretive control to the model on dimensions where you had a specific requirement. Each of the seven mistakes below is a different way of doing that — and each has a specific, testable fix. Mistake 1: Placing Critical Instructions in the Middle of the Prompt Language models process all tokens simultaneously through attention mechanisms , but the effective weight any individual token receives depends heavily on its position. Instructions near the beginning and end of a prompt receive disproportionately more attention weight than those in the middle. This is not a quirk — it is a consequence of how positional embeddings interact with self-attention across long contexts. This effect is well-documented. The "Lost in the Middle" study (Stanford / UC Berkeley, 2023) showed that retrieval accuracy from long-context windows degrades significantly for information placed in the middle — even in capable models. The same mechanism applies to instruction prompts: GPT-4o and Claude 3.5 Sonnet both exhibit measurably lower constraint adherence for instructions buried mid-context compared to those at the leading or trailing position. Open-weight models including DeepSeek-V3 and Llama 3 display the same positional bias — this is not a proprietary model quirk, it is a structural property of the transformer architecture. T

One day the browser automation flow started failing right after plugin updates with NameError: name 'plugin_form_selectors' is not defined in the post-update "residual check" step. The refactor that introduced this had landed back in v1.6.1. The error didn't surface until many rounds later. Reading the code, the cause is obvious in seconds — but nobody hit it for ages, because Python's lazy evaluation kept the leftover reference hidden until exactly the right execution path ran. This post walks through what the bug was and how we structurally prevented its kind via an AST static-analysis test. What happened — a reference that crossed a scope boundary browser_utils.py has two functions involved: run_browser_update_flow() , which orchestrates the whole update flow, and browser_update_remaining_plugins() , which handles only the plugin-update logic. The list of plugin-form selector candidates, plugin_form_selectors , used to be a local variable inside run_browser_update_flow() . In the v1.6.1 refactor — "let's split plugin update into its own function" — we created browser_update_remaining_plugins() and moved the plugin_form_selectors definition into it . # After v1.6.1 refactor def browser_update_remaining_plugins ( page , site , update_url ): plugin_form_selectors = [ # ← defined here ' #update-plugins-table-wrap form ' , ' form[name= " upgrade-plugins " ] ' , ' form[action*= " do-plugin-upgrade " ] ' , ' .plugins-php form ' , ] # ... update logic ... def run_browser_update_flow ( site , page ): # ... call to plugin updater ... browser_update_remaining_plugins ( page , site , update_url ) # ★ post-update "residual check" still uses the old local name for selector in plugin_form_selectors : # NameError if page . locator ( selector ). count () > 0 : pending_browser . append (...) The " after updating, make sure no plugin update forms are still visible " residual check stayed in run_browser_update_flow() . During the refactor, the call to extract this loop alongside the

Have you ever been in a computer lab, classroom, or office where you needed to quickly send a file between your phone and laptop? I run into this problem all the time. Sometimes there's no USB cable, no pendrive, Bluetooth is painfully slow, or uploading to cloud storage just to download the file on another device feels unnecessary. So I decided to build SilentShare . What is SilentShare? SilentShare is a browser-based peer-to-peer file sharing application that lets you instantly share: 📁 Files (up to 50 MB) 💻 Code snippets 📝 Text 🖼️ Images No installation. No account. No server storing your files. Your data goes directly from one device to another using WebRTC . Whether you're sending files from your phone to your laptop, between classmates, or across the internet, SilentShare keeps the process simple. Why I Built It I wanted something that: Opens instantly in any browser Doesn't require creating an account Doesn't upload files to someone else's server Works on desktop and mobile Feels lightweight and fast Instead of relying on cloud storage, I wanted the browser itself to become the transfer tool. Features ✨ Peer-to-peer file transfer using WebRTC 📂 File sharing up to 50 MB (including ZIP files) 🔒 Optional end-to-end encrypted rooms using AES-GCM 📷 QR code invitations with built-in camera scanner 📊 Live progress, transfer speed, ETA, pause & resume 🖼️ Preview support for: Images Audio Video PDFs 💻 Share code snippets with syntax highlighting 👥 Multi-user rooms (around 5 participants) 🌙 Dark & Light mode 📱 Installable as a Progressive Web App (PWA) How It Works Create a room Receive a random room code Share the code, QR code, or invite link Other devices join Start sharing instantly The files are transferred directly between devices instead of passing through a storage server. Privacy One of the goals of SilentShare was privacy. No user accounts No cloud storage No permanent database Nothing stored after the browser tab closes If you set a room password, all transf

In my last post I said that for normal HTML pages, element-based automation ( find / read_page ) beats coordinates every time. This post is about the apps where that advice is useless. Flutter Web apps. Canvas-rendered editors. Every button and panel you can see on screen doesn't exist in the DOM — it's all pixels painted onto a single canvas. find returns nothing. read_page 's accessibility tree is effectively empty. I got Claude to drive the Rive editor (an animation tool built with Flutter) all the way through selecting assets and exporting them. Here's the procedure that survived contact with reality. Step zero: confirm you're actually in this situation Coordinate automation is fragile, so you should only accept it after ruling out the alternative. The test is quick: run read_page . If the visible UI has almost no corresponding nodes, you're looking at a canvas-rendered app, and coordinates are the only interface you have. The four rules 1. Wait for the window size to settle before anything else Same failure mode as my previous post: right after load, the viewport hasn't reached its final width (I measured 1664→1920 over 2–3 seconds), and clicks based on an early screenshot land to the right of the target. Read innerWidth via javascript_tool twice; only proceed when two consecutive reads match. But matching innerWidth alone isn't enough — also confirm devicePixelRatio hasn't changed since the screenshot you're about to act on (a follow-up to my previous post surfaced this: when DPI or scaling changes, the whole coordinate space rescales the same way, but the new values stabilize immediately, so an innerWidth -only check can't catch it). Canvas apps deserve extra paranoia here, because there is no element-based fallback when a click misses. 2. Read text by zooming, not by extracting Text painted on canvas can't be pulled out of the DOM. To read a menu item or panel label, zoom into that region and read the enlarged screenshot as an image.

I Built an AI-Powered CLI That Migrates Legacy Java Code to Java 17/21/25 If you've spent any time in enterprise Java, you know the feeling. You open a service that's been running since 2014 and you're greeted by walls of anonymous inner classes, verbose null checks, Collections.unmodifiableList wrapping a new ArrayList , and switch statements with more break keywords than actual logic. Individually each pattern takes 30 seconds to fix. But across a codebase with 300 files, it's a week of mechanical work — and that's before you factor in the code review. So I built java-migrate : a CLI tool that scans your Java files, detects legacy patterns, and sends them to Claude with a precise system prompt to get them modernised. One command, instant diff, no surprises. What it looks like in practice Here's a typical legacy file before migration: public class LegacyService { // POJO with getters/setters public static class User { private String name ; private int age ; public String getName () { return name ; } public void setName ( String name ) { this . name = name ; } public int getAge () { return age ; } public void setAge ( int age ) { this . age = age ; } } public List < User > sortUsers ( List < User > users ) { // Anonymous Comparator users . sort ( new Comparator < User >() { @Override public int compare ( User a , User b ) { return a . getName (). compareTo ( b . getName ()); } }); return Collections . unmodifiableList ( users ); } public String describeObject ( Object obj ) { // instanceof + cast if ( obj instanceof String ) { String s = ( String ) obj ; return "String of length " + s . length (); } return "Unknown" ; } public String classify ( int value ) { // switch statement String result ; switch ( value ) { case 1 : result = "one" ; break ; case 2 : result = "two" ; break ; default : result = "other" ; } return result ; } } Run java-migrate LegacyService.java --dry-run --verbose and you get this diff: - public static class User { - private String name; - privat

Every time I shipped something, the same thought hit me a few hours later: It works on my machine. It works in staging. But is it actually working for the people using it right now? I had analytics. I had a green dashboard. And I still had no honest answer to that question. Users would quietly leave, a button would silently break on Safari, a page would crawl on a mid-range Android, and I'd find out days later, if at all. That gap is what I ended up building HeronSignal to close. But before I talk about the tool, let me talk about the pain, because I think you've felt at least one version of it. The pain, depending on who you are If you're a vibe coder / solo builder You ship fast. Cursor, Claude, v0, a Vercel deploy, and it's live. Beautiful. Then… nothing. You have no idea what happens after "Deploy successful." Is the checkout button throwing an error on mobile? Is your landing page slow enough that half your visitors bounce before it paints? You don't know, because setting up "real" monitoring feels like a second job: a Datadog dashboard you'll never look at, a Sentry config you half-finish. So you just… hope. And hope is not a monitoring strategy. If you're an engineer Your problem isn't no data. It's too much . Ten dashboards, alert fatigue, a Sentry inbox with 400 issues where 390 are noise. Something's clearly wrong, but which thing actually matters? You spend your morning triaging instead of fixing. And when you finally pick an error, you get a stack trace with zero context: no idea what page it happened on, what the user was doing, or how to reproduce it. Triage is not the job. Fixing is the job. But the tools make you do the triage first. If you're a product person You can see in your funnel that people drop off at step 3. What you can't see is why . Was it a JS error? A slow page? A confusing layout? Your analytics tool tells you what happened but never why , and the engineering dashboards that might explain it are unreadable walls of numbers. So you gue
