vLLM is an open-source inference engine that serves large language models. This blog post describes how an inference request travels through vLLM's OpenAI-compatible API server and core engine. It focuses on the new V1 architecture of vLLM and how it achieves state-of-the-art text generation performance. Readers should be familiar with the transformer architecture and large language models - a link to a video by OpenAI co-founder Andrej Karpathy that explains these is available.

Newly elected President Lee Jae Myung has made Korean won–based stablecoins a national priority, aiming to reduce capital outflows and improve monetary independence. Proposed legislation would lift the ban on won-backed stablecoins, create a licensing regime, and promote usage across industries like gaming and e-commerce. While critics argue the won lacks global demand and risks becoming a proxy-CBDC, supporters say there's real utility for cross-border trade and digital Korean services.

REX Shares and Osprey Funds received SEC sign-off on June 28, clearing the launch of two C-corporation ETFs – ESK for Ethereum and SSK for Solana – that will both track spot prices and distribute onchain staking rewards to holders. By electing C-corp status, these funds will internally tax staking distributions before paying them out as dividends, charging a 0.75% management fee. US spot Ethereum ETFs have traded for nearly a year and only futures-based Solana ETFs exist today. Both products will list on Cboe BZX, using this legal workaround to expedite the availability of staking-yield ETFs.
2025.06.30·links.tldrnewsletter.com·5 min read·TLDR Crypto Republic is launching Mirror Tokens to give retail investors economic exposure to private companies' future valuation events for as little as $50 via Apple Pay or stablecoins. The tokens aren't equity but track performance based on predefined triggers, using secondary-market data to set initial pricing, and are subject to a $5,000 purchase cap under US exemptions. After a lock-up period, holders will be able to trade on a regulated secondary marketplace. Built on Solana for low-cost, global accessibility, the Mirror Token framework will start with SpaceX and soon expand to firms like xAI, Ramp, and Perplexity, opening private-market opportunities to everyday investors.
This early framework outlines the essential services needed to bring stablecoins into mainstream finance. It includes identity-linked wallets for compliance, crypto-to-fiat conversion rails for domestic and cross-border payments (e.g. FedNow and SEPA), card payments with fraud prevention, and yield-bearing savings accounts integrated with lenders or DeFi protocols. The stack aims to mirror legacy banking (accounts, cards, and savings), but with stablecoins at the core, unlocking faster, cheaper, and more programmable financial services.
Crypto embodies the native financial layer of the internet, offering ownership, composable financial tools, and a meritocratic attention economy that aligns with Gen Z's values and need for new wealth-generation paradigms. Sustainable success in crypto comes from deep due diligence, clear theses, and patient accumulation. There is a bullish macro outlook driven by anticipated Fed rate cuts and dollar weakness. This author's high-conviction positions include revenue-yielding protocols (SYRUP, EULER, and Pendle), cycle winners like HYPE, and infrastructure bets on Solana and its ecosystem.
2025.06.30·links.tldrnewsletter.com·11 min read·TLDR Crypto Despite having a billion users and the TON blockchain, Telegram is losing the miniapps battle to Farcaster due to systemic issues including millions of botted users, copy-paste projects with no real impact, and a February 2025 mandate requiring all miniapps to integrate TON blockchain, which caused significant developer backlash. A report revealed TON's declining ecosystem metrics, while builders are increasingly migrating to Farcaster which offers real users instead of bot armies, quick iteration cycles, and multi-chain support from Solana, Celo, and Monad. Farcaster is prioritizing sustainable ecosystem development over quick wins.
Polygon's new “Gigagas Roadmap” outlines aggressive scaling targets: 1,000 TPS and ~5s finality by July, ramping to 5,000+ TPS and 1s block times by year-end.

Google's Doppl is an experimental AI app that creates digital versions of users to try on clothing from photos or screenshots virtually. Users upload full-body images and then select outfits to see how they'd look, with options to generate videos and share the results.

Apple's new “Liquid Glass” design in iOS 26 marks its most dramatic visual shift since iOS 7, replacing static flat design with a dynamic, glass-like material that bends light, reacts to touch, and conveys depth through motion and translucency. More than just visual flair, this approach introduces a new paradigm — computational design — where UI elements behave like responsive, living materials, reshaping how designers and developers think about consistency, accessibility, and user experience.
Product designers often struggle to demonstrate impact when their work doesn't directly relate to revenue metrics, such as ROI or conversion rates. This article outlines alternative impact areas, including time savings, cost reduction, process simplification, and improved internal metrics that designers can measure and present to stakeholders. A technique from Leadership Ateliers involves mapping how design decisions create ripple effects across multiple departments, teams, and user personas simultaneously.

A new rumor from leaker Majin Bu suggests Apple may reposition the Apple logo on the iPhone 17 Pro, moving it below the new rear camera bar instead of keeping it centered. While the claim is unconfirmed and somewhat questionable, similar leaks from case manufacturers have proven accurate in the past, lending some credibility to the speculation.
A developer analyzed Apple's new Liquid Glass effect by breaking it down into layered CSS and SVG techniques, including inset shadows for edge highlights, `backdrop-filter` for blur and color adjustment, and custom SVG filters for light refraction, ripple distortion, and chromatic aberration. While the effect can be convincingly replicated with modern CSS and SVG, it's not fully supported across browsers like Safari or Firefox, and its high GPU cost limits its use to select UI elements rather than full interfaces.
Loading spinners have evolved from symbols of hope into sources of user frustration, representing broken systems rather than actual progress. While spinners endlessly rotate without providing meaningful feedback, alternatives like progress bars and skeleton screens offer users honest, structured information about what's happening. The relationship between users and loading spinners has deteriorated to the point where the spinning icon now triggers anxiety and abandonment rather than patience.

Half of U.S. public companies have vanished in 30 years because staying private got way easier. Companies can now raise billions without IPOing and investors can still cash out through private deals. The wild part is that companies are getting bought and sold between private investors like trading cards, creating "fake liquidity" where you think you're getting your money out but you're really just owning the same company through a different fund.
Hinge Health's IPO delivered gains for early-stage investors while disappointing late-stage backers, fueling cautious optimism for other healthtech IPOs.

Every major tech platform follows the same playbook: open the gates to developers, let them build value, then squeeze them out once dominance is achieved—and AI platforms are about to enter this cycle. The brutal reality is you have months (not years) to pick your platform, bet, and build something defensible before the gates close, because as Cursor's demolition of GitHub Copilot shows, the innovation replication cycle has compressed from 24 months to just 3-6 months.
LLMs heavily weight Wikipedia as a trusted source. Having a presence there can significantly boost your company's visibility in AI-generated responses, but only if you follow the strict rules.
