WHEN MEMORY WAS MEASURED IN KILOBYTES: THE ART OF EFFICIENT VISION

In the early days of computer vision, when memory was extremely limited, researchers at Inria developed "An Efficient Chain-Linking Algorithm" to extract meaningful information from images. This algorithm, created by the PASTIS team, processed images line by line, storing only a few lines at a time, making it memory-efficient. The code's dynamic memory allocation was ingenious and was necessary.

EXPLAINER FOR LOCAL NETWORK ACCESS

The Chrome Secure Web and Network team has proposed a new "Local Network Access" feature to mitigate security risks from websites probing and attacking devices on local networks. It will require user permission before a website can make requests to a private IP address or loopback, unlike the previous Private Network Access (PNA) proposal which relied on preflight requests. This approach involves gating local network requests behind a permission prompt, giving users more control over which sites can access their local network.

BEYOND 2NM: APPLE'S A20 CHIP TO INTRODUCE NEW PACKAGING BREAKTHROUGH

Apple's A20 chip, built on TSMC's second-gen 2nm process, will be used in the iPhone 18 Pro, 18 Pro Max, and iPhone 18 Fold. The processors use Wafer-Level Multi-Chip Module packaging, which allows different components to be integrated directly at the wafer level. The technique, which connects the dies without needing an interposer or substrate, brings both thermal and signal integrity benefits. This is a big leap in chip design and shows how technologies once reserved for data center GPUs and AI accelerators are making their way into smartphones.

WHY GUIS ARE BUILT AT LEAST 2.5 TIMES

Your mental model for 'what making software is' is extremely important when trying to figure out how to 'manage' it. A lot of what is essential for making great products will look like 'waste' when viewed through a manufacturing lens. When 'making software' is viewed as a process of discovery, developers behave completely differently - they might try to get something into users' hands as fast as possible or run parallel experiments in production with different versions. The goal isn't just to produce, but to find out what should be built.

META AND YANDEX ARE DE-ANONYMIZING ANDROID USERS' WEB BROWSING IDENTIFIERS

Meta and Yandex Are embedding tracking code into millions of websites to de-anonymize visitors. The code abuses legitimate Internet protocols, causing browsers to send unique identifiers to native apps installed on a device. It bypasses core security and privacy protections provided by the Android operating system and the browsers that run on it. Currently, the only way to protect against the tracking is to refrain from installing the Facebook, Instagram, or Yandex apps on Android devices.

DOES AI PROGRESS HAVE A SPEED LIMIT?

The external world puts a speed limit on AI development. Systems need to be tested in real-world conditions to encounter failures they can learn from. Edge cases can be learned, but that will often need to happen while doing real tasks. This creates a speed limit in two ways: you have to wait to collect that data and some people may be reluctant to try out the technology while the system works out its bugs.

MY AI SKEPTIC FRIENDS ARE ALL NUTS

A veteran developer rails against the many highly-skilled programmers still rejecting LLMs based on experiences with early chatbots, missing how modern coding agents autonomously navigate codebases, run tests, and iterate on failures. He dismisses common objections: developers already review all code before merging regardless of source, and hallucinations become irrelevant when agents can automatically compile, catch errors, and retry until tests pass. LLMs might displace developers but software engineers similarly automated away administrative roles like travel agents, record store clerks, and countless other professions.

US MILITARY LEADERSHIP TO BACK BITCOIN STRATEGIC RESERVE

Senator Lummis stated that U.S. military leaders, particularly generals stationed in Southeast Asia, support creating a national Bitcoin reserve as a strategic hedge amid economic tensions with China. She argued that holding BTC would strengthen the U.S. in both economic and military conflicts, noting the administration's broader “economic war” narrative. Lummis' remarks align with Trump's push to make the U.S. a crypto leader and contrast with China's comprehensive crypto ban despite its own digital Yuan development.

INFINIFI: AMPLIFIED YIELD

InfiniFi introduces an onchain fractional reserve banking model that allocates a portion of “liquid” stablecoin deposits into higher‑yield “illiquid” farms to boost returns for both liquid and locked depositors without adding new protocol risk. Users choose between staking ($siUSD) for instant access or locking ($liUSD‑xw) for higher illiquid yields. InfiniFi then intelligently leverages part of the liquid pool into long‑duration strategies, amplifying overall yield. The only liquidity risk arises if liquid depositors withdraw en masse, but this pressure diminishes as total value locked grows, mirroring traditional banking resilience.

STABLECON TAKEAWAYS

There was a surprising lack of understanding around USDT's historical importance in U.S. crypto circles at the Stablecon conference. Western markets are primarily driven by stablecoin programmability while emerging markets value their permissionless nature. The real profit opportunity lies in FX orchestration layers, which will need massive transaction volumes to achieve scale. Stablecoin user experiences differ greatly between U.S. savers/spenders and users in other regions. Tether's continued dominance is attributed to its strong user and liquidity network effects, while local stablecoins will require integration into a global USDT liquidity pool to succeed.

CIRCLE IPO - TIME FOR STABLECOIN SUMMER?

Circle is set to IPO on June 5 under the ticker CRCL, aiming to raise $624 million at a $6.7 billion valuation. Cathie Wood's ARK is committing $150 million and BlackRock's Larry Fink $60 million, about 35% of the total raise, and the deal is reportedly oversubscribed. As a traditional IPO with a 180‑day lockup, CRCL could trade above its $6.7 billion launch valuation, offering one of the only liquid ways to bet on stablecoin growth and blockchain's expansion amid a forthcoming GENIUS Act. How CRCL performs may set relative valuation benchmarks for DeFi projects, making issuers with stablecoin exposure appear more attractive and potentially catalyzing a “Stablecoin Summer” by lifting valuation ceilings.

INFOFI'S COBRA EFFECT

InfoFi's promise to tokenize and democratize off-chain data has backfired, turning platforms like Crypto Twitter into spam factories where bots and airdrop hunters flood sentiment and mindshare metrics. Efforts to tokenize social capital, ranging from token-gated content and social tokens to onchain social graphs, have incentivized engagement over accuracy, worsening information quality. This “cobra effect” traps InfoFi in a narrow loop of repetitive, copy‑paste solutions that fail to address real needs and generate continual hype cycles. Genuine progress requires sourcing data outside of engagement-driven social consensus rather than building more coordination layers atop a flawed foundation.

ETHEREUM THESIS – ROOT CHAIN FOR THE WORLD COMPUTER

Ethereum evolved into the leading smart contract platform by prioritizing security and decentralization, which enabled it to capture DeFi's product-market fit and accrue value via fee burns. Faced with scalability constraints, Ethereum embraced a rollup‑centric roadmap, offloading execution to Layer 2s and expanding data availability to keep transaction costs low while onboarding high‑velocity use cases. The main challenge today is ensuring rollup interoperability and restoring strong network effects like trust and liquidity by positioning Ethereum as the unifying settlement and DA layer for all rollups. Long term, Ethereum's strategy is to scale L1 throughput, solve cross‑rollup interactions, and gradually introduce minimal blob pricing to capture massive fee revenue as rollup adoption surges.
