The Samsung Galaxy Z TriFold is set to launch in the US early next year. Its inner display measures 10 inches across. The phone's specs are overall pretty similar to the Galaxy Z Fold 7, though the battery is quite a bit bigger at 5,600 mAh. The device will come only in 'Crafted Black'. It only measures 3.9mm at its thinnest unfolded point. When folded up, the device measures 12.9mm thick, which is markedly thinner than the Galaxy Z Fold 5, which was only released two years ago.
Neuralink is considering an upgrade for its first human patient. Since receiving the implant, the patient has been able to play games, attend classes, and work. He is currently studying neuroscience and maintaining good grades, something that would be impossible without Neuralink. An upgrade would allow him to perform even more sophisticated tasks using only his mind.

Punycode is a special encoding used to convert Unicode characters to ASCII. It's deceptively simple on the surface, but there's real sophistication in how it manages the problems inherent in encoding arbitrary Unicode within DNS' ASCII-only infrastructure. The algorithm uses adaptive bias adjustment, variable-length encoding, and delta compression to achieve extremely dense results. This article looks at how to encode arbitrary Unicode within DNS's ASCII-only infrastructure. It provides a step-through visualizer at the end that lets readers watch the algorithm encode domains from various scripts.
The same coding standards applied to production code should also be applied to test code. Test code needs to be readable, well-factored, and reviewed, just like production code. Good code makes it easier for people working on the code to read, understand, and update. Applying coding standards and design principles to test code makes maintainability easier.
Interest in understanding, using, and learning how to build AI technologies is soaring. Schools are racing to meet rising student and industry demand. Dozens of universities and colleges in the US have announced new AI departments, majors, minors, courses, interdisciplinary concentrations, and other programs. Students hope that the AI branding will open up more job opportunities.
Instagram employees will be required to return to the office beginning February 2. Employees will still be able to work remotely when needed, but they have been asked to use their best judgment on when to take advantage of that flexibility. Other planned changes intended to make Instagram more nimble and creative next year include the scaling back of recurring meetings and a faster process for unblocking and decision-making. While executives insist that in-person work has important benefits, employees often disagree.

You want AI to become part of your organizational DNA - and that means enabling every department to build out their own use cases, without IT gatekeepers standing in the way. But it shouldn't mean an ungoverned free-for-all.
Gen-4.5 topped the Artificial Analysis text-to-video benchmark, ahead of Veo 3 and Sora. The model emphasizes physical accuracy (realistic momentum, fluid motion, and material coherence). Runway has acknowledged persisting issues with object permanence.
Google has been working on a new 'projects' option for Gemini. The feature will allow users to sort files and chats around particular topics. Projects can be pinned for easy access. There is a 10-file limit, but paying users may receive a higher ceiling.
OpenAI trained an agentic code reviewer for Codex since noisy safety tools are inevitably bypassed. The system now handles 100k+ external PRs daily, providing repo-wide context and execution access. Internally, it has caught launch-blocking bugs and protected high-stakes experiments.
Models don't know what is 'out of distribution' for themselves. Engineers will always be required in the loop until this problem is solved. It will never be easy to check the accuracy of models. Researchers need to look at their data, make sure it's clean, and label it correctly.
The Google DeepMind mechanistic interpretability team has pivoted to a pragmatic approach to interpretability over the last year. It is important to have empirical feedback on goals with good proxy tasks. Near-complete understanding isn't required for significant impact. Good focused projects start with a theory of change, and good exploratory projects start with a robustly useful setting.

ByteDance's Doubao app is now China's most popular mobile AI platform. It received more than 11.4 million downloads in October. Doubao's focus on frictionless AI-powered voice, image, and video experiences sets it apart from competitors. ByteDance keeps its most advanced technology proprietary, breaking away from China's open-source approach. This could give it a durable commercial edge.
Accenture will deploy ChatGPT Enterprise to tens of thousands of its professionals, marking the largest upskilling effort yet via OpenAI Certifications.
Most traders lose money before they even place a trade. Bridging USDC into Hyperliquid [4] means eating slippage, swap fees, and bad execution along the way.
China's inter-agency meeting reiterated that virtual currencies lack legal fiat status, with all related activities constituting illegal financial operations. Vowing intensified crackdowns on speculative trading, the meeting specifically warned that stablecoins lack proper KYC and AML protections, enabling money laundering, illicit cross-border financing, and fraud, contrasting sharply with the US' favorable stablecoin regulatory environment under the recent GENIUS Act framework. The announcement comes despite China reemerging as the world's third-largest Bitcoin mining hub while Hong Kong operates under a separate autonomous jurisdiction with government-supported crypto initiatives.
Kalshi is facing a nationwide class action lawsuit alleging it operates an illegal sports betting platform by positioning institutional market makers, including Kalshi Trading and Susquehanna, as "the house" with zero fees, enhanced access, and position limit advantages while misleading customers that they're betting peer-to-peer. The complaint claims 90% of September's $2 billion volume came from sports betting despite running ads falsely stating "legal sports betting in all 50 states" and targeting college campuses through KalshiU partnerships with a 15-year-old gaming influencer. Plaintiffs seek treble damages, restitution, and injunctive relief across a nationwide class and 30 state subclasses, including California and Florida, where Kalshi allegedly violates Penal Code 337a, which bans pool selling and bookmaking. The lawsuit argues Kalshi disguises gambling as "sports trading" and "build your combo" parlays while enabling addictive behavior without the safeguards required by regulated sportsbooks.
Bastion will act as the sole issuance provider for Sony Bank's new USD-backed stablecoin initiative, handling token issuance, reserve management, and custody for Sony affiliates. The deal marks Sony Bank's entry into the US stablecoin and digital-asset market, using Bastion's regulated infrastructure to support wallets, on/off ramps, cards, and yield products. Backing from Sony Innovation Fund, Coinbase Ventures, a16z crypto, and others demonstrates that large enterprises increasingly want white-label, compliant stablecoin rails rather than building everything in-house.
Shift is building a validator-free payment system where tamper-resistant secure elements confine private keys inside hardware that tracks balances, prevents double-spends, and signs transactions internally without ever exposing key material, even under physical attack. Remote attestation using factory-provisioned keypairs proves each device is legitimate, unmodified hardware following protocol rules, with one-time addresses generated and consumed atomically alongside cryptographic proofs verified by recipient hardware. Transactions settle device-to-device with the finality of cash exchange but cryptographic guarantees, as secure elements consume UTXOs irreversibly, sign with confined keys, and generate change addresses while attaching attestations that trace to manufacturer root certificates. The architecture eliminates validators, ledgers, and seed phrases by moving trust from consensus to tamper-resistant silicon, enforcing strict state transitions where balance accounting and signing happen as single atomic operations, preventing intermediate or inconsistent states.
Quantum computing poses an existential risk to Bitcoin as Shor's algorithm running on 2,000 logical qubits could reverse-engineer private keys from public keys, with 6.7 million BTC vulnerable, including 1.7 million in Satoshi's exposed p2pk addresses and 4.8 million in reused addresses. Evidence suggests CRQCs will arrive by 2035. Threat scenarios range from North Korea monetizing exploits to China weaponizing quantum breaks against US-associated Bitcoin to lawful seizure by American entities protecting the strategic reserve.

Ethereum's main programming language, Solidity, is being upgraded to look and behave more like modern, safer languages. The goal is to make smart contracts easier to write, reuse, and much harder to break. If Ethereum pairs this with scaling, privacy, and better L2 integration, competitors won't be able to keep up.
Solana's 1,232-byte transaction limit and accounts model make complex multi-hop swaps impossible compared to Ethereum, where 50-hop swaps across 37 tokens work trivially, with Account Lookup Tables providing cumbersome workarounds requiring V0 transactions and prior construction. There are three solutions: validator-side account lookups allowing automatic derivation instead of payload inclusion, top-level return value passing eliminating scratch accounts for instruction composition, and native bundling with instruction-level signatures removing round-trip bottlenecks between parties. Widespread bundling adoption, massive instructions, and core infrastructure's ALT reliance signal the network wants composability as markets mature toward more expressive applications. Proposed changes enable high-frequency off-chain apps using Solana for atomic settlement.
Cash App and Square are now offering in-app payments with just a 1% processing fee, powered by a pooled stored balance that already sees ~$300B flow through Cash App annually. The combo of low fees, huge user base, and tight merchant integration likely kills the window for crypto-native POS startups to gain serious distribution as Block's network effect and UX moat make it extremely hard to compete.
Amundi, Europe's largest asset manager with €2.2T AUM, quietly launched a tokenized money market fund on Ethereum on November 4 and only announced it weeks later.
