A Monster Energy–sponsored MMA show on the White House’s South Lawn was never going to be the height of dignity. But UFC Freedom 250 is failing to clear even the lowest bar.

SpaceX’s stock market debut has thrust the richest man in the universe into an unexplored frontier of wealth.

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."

GOP lawmakers, tech investors, and even OpenAI have tied the anti-data center movement in the US to Chinese interference. Experts say it’s much more complicated than that.

Even moderately sized data centers can have an outsized local impact.

The fraudsters allegedly targeted hundreds of thousands of people with Gemini-coded scams sites.

Elon Musk is now officially the world's first trillionaire. That is a colossal amount of wealth (and by proxy, power) for one individual to have. Its scale - a thousand times more than a billion - is difficult to fathom for those of us who aren't among the 3,363 billionaires that currently exist in our […]

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 […]

TypeScript Compile Error TS2802: Resolved with Observer Pattern by Converting Set Spread to Array.from If you're stuck implementing the observer pattern due to TypeScript compile error TS2802, this post might help. I resolved the issue with a simple conversion: changing Set spread to Array.from() . Attempts and Pitfalls While implementing the observer pattern, I encountered TypeScript compile error TS2802 when trying to spread a Set. Initially, I suspected the Set's type might be the problem, so I tried various approaches. class Observer { private subscribers = new Set < () => void > (); subscribe ( callback : () => void ) { this . subscribers . add ( callback ); } notify () { // TS2802 error occurs here for ( const callback of [... this . subscribers ]) { callback (); } } } When attempting to spread the Set into an array using [...this.subscribers] as shown above, TypeScript failed to recognize it properly, throwing an error similar to TS2802: Cannot find module '...' or its corresponding type declarations. . At first, I thought it was a library configuration issue and spent a considerable amount of time lost. The Cause In the end, the problem lay with the Set spread syntax itself. When TypeScript applies the ... spread operator to a Set, there were instances where it couldn't accurately infer the types internally. This issue can be more pronounced in certain versions or environments. The Solution To resolve this, I used the method of explicitly converting the Set spread to an array using Array.from() . class Observer { private subscribers = new Set < () => void > (); subscribe ( callback : () => void ) { this . subscribers . add ( callback ); } notify () { // Resolved by converting with Array.from for ( const callback of Array . from ( this . subscribers )) { callback (); } } } By using Array.from(this.subscribers) , TypeScript clearly recognizes the Set as an array, allowing the loop to execute correctly. The Outcome The TypeScript compile error TS2802 was cleanl

A quick note on the links below. The DigitalOcean and Vultr links in this article are referral links. If you sign up via them, you get a free credit on your new account (currently $200 over 60 days for DigitalOcean and up to $300 for Vultr) and the author of this article gets a small referral credit too, at no extra cost to you. AWS does not run an equivalent referral program, so the AWS links are normal links. The review below is the author's own evaluation; the credits do not change the recommendations. If you have ever spent a workday watching your website refuse to load, you are not alone. In a recent outage , a single building in Northern Virginia hosting one of Amazon's availability zones (the cloud-industry term for one campus's worth of servers in one region ) got too hot. The hardware shut itself down. AWS calls this a thermal event. Customers around the world have other names for it. Big enterprises ride out outages like this. They have multi-region setups, dedicated SRE teams, and SLA credits that will refund a small fraction of their monthly bill. Small and mid-size businesses do not. They lose a day of revenue, scramble to reassure customers, and then read a post-mortem in a few weeks that explains what went wrong in language that does not help them recover the lost revenue. The cloud was supposed to make small businesses look big. After each new outage, it is fair to ask: is AWS actually the right cloud for small businesses at all? Two providers worth a serious look, DigitalOcean and Vultr , are simpler, cheaper at the entry level, and built around use cases that more closely match what a small business actually needs. Here is what each one does, where AWS is still the right answer, and how to decide. Why AWS hits small businesses harder than big ones When a giant company has an AWS outage, three teams kick into gear. There is the engineering team that fails workloads over to a backup region. There is the customer-success team that updates the status p

Two HNG Tasks That Taught Me More Than the Spec This is my Stage 9B write-up for the HNG internship . No new code just two tasks that stuck: one I owned solo across multiple repos, and one I shipped inside a team product under real deadline pressure. If you've ever had auth work almost done for three days straight, or watched an LLM politely ignore your JSON schema, you'll recognize these stories. Task 1 (Individual): Insighta Labs — One API, Three Clients, One Auth System Stage: 3 (Technical Requirements Document / TRD track) Why I picked it: Auth looked "done" on paper. It wasn't. Web portal, CLI, and graders all needed to log in differently, and every environment (localhost, Railway, preview URLs) found a new way to break. What it was Insighta Labs is a queryable profile-intelligence API I built during HNG. By Stage 3 the backend wasn't just CRUD anymore it needed GitHub OAuth with PKCE , JWT access + refresh with rotation , RBAC ( admin vs analyst ), rate limits, API versioning, and three first-class clients : Client Repo How it authenticates Backend API HNG_STAGE-1 Issues tokens, sets cookies Web portal Insighta-WebPortal HTTP-only cookies + CSRF CLI Insighta-Cli PKCE + local callback + Bearer tokens Every /api/* route required X-API-Version: 1 and a valid session. Access tokens expired in 3 minutes ; refresh tokens in 5 minutes with rotation. That sounds harsh, it was intentional, and it surfaced bugs fast. The problem it was solving Reviewers and real users had to prove identity without sharing one login mechanism. Browsers should never see raw tokens in JavaScript. The CLI can't use cookie redirects the same way a React app does. Automated graders needed a test path that didn't depend on GitHub's OAuth exchange. One auth design. Three runtimes. Zero "works on my machine only." How I approached it I split auth into explicit paths instead of one generic "login" handler: Web flow GET /auth/github — server stores PKCE verifier, redirects to GitHub GET /auth/gith

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.
