The funding round would value the company at around €20 billion (about $23.15 billion), nearly double its Series C valuation of €11.7 billion.

The tech giant said a group called "Outsider Enterprise" used AI to scam hundreds of thousands of victims, sending 2.5 million text messages over a span of two weeks.

Winning fight against AI data centers gives people a "taste of political power."

You'd be forgiven for thinking this day would never come. Siri has spent a decade and half somewhere between "sort of useful at a few things" and "utterly disastrous, why did I even try, can it honestly not even set a timer." But the wildest thing just happened: Apple put out a new version of […]

Elon Musk's net worth has passed the trillion-dollar mark after SpaceX's IPO. His net worth, which was hovering around $800 billion before the IPO, includes the value of his 4.8 billion shares in SpaceX, along with his wealth from his other companies, like Tesla. Shares of SPCX opened at $150 and have remained well above […]

The IPO market is back, and it’s not the same companies leading the charge. FAANG had a good run, but a new acronym is taking over: MANGOS — Meta (or Microsoft, depending on who you ask), Anthropic, Nvidia, Google, OpenAI, and SpaceX. Half of that bunch is heading to public markets in the same window, and it’s a stress test for investors, for valuations, and for […]

TL;DR: Your AI coding assistant is a generalist. It writes Flutter that looks right but quietly reaches for 2022 patterns. Agent Skills are a new, official way (from the Dart and Flutter teams) to hand your agent task-specific, battle-tested workflows it loads on demand. Two repos, flutter/skills and dart-lang/skills , ship ready-to-use skills for responsive layouts, routing, testing, localization, static analysis, and more. Install in one command: npx skills add flutter/skills --skill '*' --agent universal npx skills add dart-lang/skills --skill '*' --agent universal This post breaks down what they are, how they differ from rules files and MCP, the full catalog, what a real skill looks like under the hood, and whether they actually move the needle. (Spoiler: mostly yes, with one honest caveat.) Let me tell you about a fight I have almost every day. I ask my AI agent to make a screen adapt to tablets. It confidently hands me code that switches layout based on MediaQuery.orientationOf(context) . It looks clean. It compiles. It even runs . And it's wrong, because device orientation has nothing to do with how much window space your app actually has on a foldable, in split-screen, or in a resizable desktop window. The model isn't dumb. It's a generalist trained on a giant pile of Flutter code, much of it old. And here's the uncomfortable truth the Flutter team said out loud when they launched this feature: Flutter and Dart ship new features faster than LLMs can update their training data. That lag has a name, the knowledge gap , and it's why your agent keeps writing rookie Flutter with a straight face. Agent Skills are the Flutter team's answer to that gap. I've been running them on real projects, and they're one of the few "AI workflow" things in 2026 that earned the hype instead of borrowing it. Let's get into it.

Did chatbot abandon mental health guardrails when a vulnerable user pushed back?

SpaceX’s IPO on Friday allows the public to buy shares of the combined rocket, AI, and social media company for the first time, and is raising enough money to likely make Elon Musk the first trillionaire. He’ll have more wealth, on paper at least, than the economies of nations like Ireland, Sweden, or his home […]

TechCrunch has followed SpaceX's start, struggles, and successes from the early days. And we're here for what happens next too. This package of SpaceX IPO coverage includes who stands to win (and maybe some who won't), pre-IPO deals, and what's tucked inside its S-1 registration document.

Amazon founder Jeff Bezos says his new AI startup will work toward developing an "artificial general engineer," according to reports from The New York Times and CNBC. The startup, called Prometheus, aims to develop AI-powered engineering tools to aid in the design of physical products. The NYT first reported on Prometheus last November, but now […]

Google's Angular team has released a repository called angular/skills, focusing on Agent Skills that enhance AI coding agents' ability to write modern Angular code. The repository includes skills for generating code and scaffolding applications, reinforcing current Angular conventions. It serves as a snapshot, aiming to improve AI suggestions by providing updated context. By Daniel Curtis

This is what most agent email code looks like today: // SendGrid / Resend / Postmark — outbound only await sendgrid . send ({ to : " prospect@example.com " , from : " outreach@yourcompany.com " , subject : " Following up on your demo request " , html : " <p>Hi Alice — wanted to follow up on...</p> " , }); // That's it. If Alice replies, the agent never sees it. The send works fine. The problem is everything after: when Alice replies, that reply bounces, lands at a no-reply nobody reads, or hits a human inbox the agent can't reach programmatically. The agent is talking into a void. Transactional providers were built for receipts and password resets — one-way mail — and an agent that's supposed to hold a conversation needs a receive path those APIs simply don't have. Agent Accounts (a beta feature from Nylas) close that gap with a full hosted mailbox: send and receive, with threading, webhooks, and folders built in. Here's what the migration actually involves. The delta, honestly Outbound barely changes — it's still an API call. The new parts are everything transactional providers never gave you: Concern Transactional provider Agent Account Outbound API call Same — POST /messages/send Inbound None (or polling a shared inbox) Replies land automatically, fire message.created Threading You track Message-ID yourself Headers preserved, threads grouped automatically Reply detection Parse forwards, poll Webhook within seconds of arrival DNS SPF/DKIM/DMARC for the provider MX, SPF, DKIM, DMARC for the mailbox host Provision the mailbox One call creates the account; the response includes a grant_id that identifies it on every later request: curl --request POST \ --url "https://api.us.nylas.com/v3/connect/custom" \ --header "Authorization: Bearer $NYLAS_API_KEY " \ --header "Content-Type: application/json" \ --data '{ "provider": "nylas", "settings": { "email": "outreach@agents.yourcompany.com" } }' (Or nylas agent account create outreach@agents.yourcompany.com from the CLI.)

If you've ever worked with AI agents in production, you know the frustration: every new session starts from scratch. The agent has no memory of previous conversations, no context about ongoing projects, and you have to repeat yourself constantly. It's like Groundhog Day for your AI. I ran into this with a code assistant I was using for a multi-week refactoring project. It was great for one-off questions, but it couldn't remember what we discussed yesterday. I'd ask it about the architecture decisions we made last week, and it would stare at me blankly. I needed something that could carry context across sessions without forcing me to patch the agent's internals. I looked at the usual suspects: vector databases for RAG, ad-hoc session dumping, even fine-tuning. Each had a cost. RAG setups are powerful but often require custom tooling and tight integration. Session logs without structure are just noise. Fine-tuning is expensive and slow to iterate on. What I wanted was a self-contained system that worked with any agent, required no code changes to the agent, and actually understood what to keep and what to forget. That's when I found Memory Sidecar. It's an open-source project designed to run alongside any AI agent—Hermes, Claude Code, Cursor, Codex, or your own custom setup—as a separate process. It watches your agent's output, archives important conversations, builds a long-term knowledge base, and injects relevant context back before each new session. No patches, no invasive changes. How it works The architecture is simple on the surface but layered underneath. Agents write sessions to state.db and session files. The sidecar reads these, processes new content, and feeds through a three-tier retrieval system: Hot layer : Recent context with a small footprint (5 KB cap). This is the stuff the agent just talked about. Warm layer : Hindsight PostgreSQL database that stores summarised sessions and recent history. Cold layer : A knowledge graph (gbrain) combined with FTS5

You built the outbound half of an email agent. It sends a well-crafted message, the recipient writes back six hours later... and your agent has no idea. The reply either gets ignored or — arguably worse — gets treated as a brand-new conversation, and the agent reintroduces itself to someone it emailed yesterday. That gap between "can send" and "can converse" is where most email agents stall. Closing it takes four pieces: detection, context, routing, and a threaded response. Here's each one, using a Nylas Agent Account (in beta) as the mailbox — a hosted address the agent owns outright. Step 1: know a reply when you see one Every message.created webhook payload carries a thread_id . If the agent sent the original message, that thread already exists in your state store. So detection is a lookup, not a parsing exercise: app . post ( " /webhooks/nylas " , async ( req , res ) => { // Verify X-Nylas-Signature here. res . status ( 200 ). end (); const event = req . body ; if ( event . type !== " message.created " ) return ; const msg = event . data . object ; if ( msg . grant_id !== AGENT_GRANT_ID ) return ; const context = await db . getThreadContext ( msg . thread_id ); if ( context ) { await handleReply ( msg , context ); // active conversation } else { await handleNewMessage ( msg ); // fresh inbound — triage it } }); Why does this work without touching a single header? Because the threading already happened upstream: messages get grouped by their In-Reply-To and References headers, which every mail client sets on a reply. You never parse them yourself — the Threads API did the work. Step 2: pull the full conversation The webhook payload is a summary — subject , from , snippet . Before an LLM decides how to answer "sounds good, let's do Thursday," it needs to know what was proposed. Fetch the full message body and the thread: const fullMessage = await nylas . messages . find ({ identifier : AGENT_GRANT_ID , messageId : msg . id , }); const thread = await nylas . thread

Ever watched an email agent reply to the same message twice? The recipient gets two near-identical responses seconds apart, screenshots them, and your carefully engineered assistant suddenly looks like a script with a stutter. Worse: under real load, this isn't a freak event. It's the default outcome if you haven't designed against it. The double-reply problem has three distinct causes, and each one needs its own fix. Let's walk through them. Why duplicates happen at all First cause: webhook redelivery . Nylas — like most webhook providers — guarantees at-least-once delivery. If your endpoint doesn't return a 200 fast enough, or a transient network blip eats the response, the same message.created notification shows up again. Process both, send two replies. Second: concurrent workers . Your handler probably runs on multiple instances — Lambda invocations, ECS tasks, worker processes. Two of them can pick up the same notification at nearly the same instant and both start generating a reply. Third: shared inboxes . Two agents (or an agent and a human) watching the same mailbox can both decide a message is theirs to answer. This one isn't a duplicate event at all — it's a coordination problem, and it's the hardest to patch at the application layer. Fix one: deduplicate deliveries Track which message IDs you've processed, and check before doing anything else: app . post ( " /webhooks/nylas " , async ( req , res ) => { res . status ( 200 ). end (); const event = req . body ; if ( event . type !== " message.created " ) return ; const messageId = event . data . object . id ; // Atomic check-and-set. If the key exists, bail. const alreadyProcessed = await db . processedMessages . setIfAbsent ( messageId , { receivedAt : Date . now (), }); if ( alreadyProcessed ) return ; await handleMessage ( event . data . object ); }); The check-and-set must be atomic. In Redis that's SET messageId 1 NX EX 86400 ; in Postgres it's INSERT ... ON CONFLICT DO NOTHING with a row-count check. G

Day 0, 10:00 — your agent sends a demo follow-up. Day 2, 14:37 — the prospect replies with a question. Day 2, 14:39 — they send a second thought. Day 5 — silence, then a reply to something the agent said a week ago. Somewhere between day 0 and day 5, your process restarted twice and deployed once. A single send-and-forget email is easy. The timeline above is the actual job: a conversation spanning five exchanges over days, where the agent has to remember what it said, what it's waiting for, and where in the workflow it stands — across restarts, deploys, and hours of dead air. The multi-turn conversation recipe builds this loop on a Nylas Agent Account (the feature's in beta), running entirely on webhooks and the Threads API — no polling, no missed messages. State lives outside the model The core design decision: every active conversation gets a durable record keyed by the thread ID. const conversationRecord = { threadId : " nylas-thread-id " , grantId : AGENT_GRANT_ID , contactEmail : " prospect@example.com " , purpose : " demo_followup " , // What started this conversation step : " awaiting_reply " , // Where in the workflow we are turnCount : 1 , maxTurns : 10 , // Safety cap before escalation lastActivityAt : " 2026-04-14T10:00:00Z " , metadata : {}, }; The step field is the heart of it — a tiny state machine tracking what the agent is waiting for, which determines how the next inbound message gets handled. The store has to be durable (Postgres, Redis with AOF, DynamoDB); the gap between messages can be days, so in-memory state is a non-starter. Starting a conversation means sending the first message and persisting the record under the threadId the send returns: async function startConversation ({ to , subject , body , purpose , metadata }) { const sent = await nylas . messages . send ({ identifier : AGENT_GRANT_ID , requestBody : { to : [{ email : to . email , name : to . name }], subject , body , }, }); await db . conversations . create ({ threadId : sent . dat
