Claude finds new cryptographic attacks that human review had missed

Anthropic says Claude Mythos Preview helped cut the effective key strength of the post-quantum HAWK signature candidate in half and found a 200–800-times faster attack on a reduced version of AES. Neither result breaks production systems, and each discovery cost roughly $100,000 in API use. The consequence is larger than a benchmark: frontier agents are beginning to produce verifiable expert research, while the economics and human validation burden remain substantial.

Dow jumps 537 points as investors rotate away from chips

The S&P 500 gained 0.2% and the Dow rose 1%, while the Nasdaq slipped 0.2% as Micron, AMD, and Applied Materials fell sharply. Brent crude settled at $82.08 and the 10-year Treasury yield eased to about 4.60%. This is a market rotation rather than a broad panic, but Microsoft and Meta earnings Wednesday will test whether AI spending can justify its price.

Google gives managed agents hooks, budgets, schedules, and a free tier

Gemini API managed agents now default to Gemini 3.6 Flash and can run custom checks before or after tool calls, cap total tokens, and fire on cron schedules. Google also opened free-tier access and added persistent sandbox management. For builders, the important step is operational: agent safety, spend limits, and recurring execution are becoming standard platform features instead of custom plumbing.

New Hampshire’s new housing law overrides local density caps

A retroactive state law now allows multifamily housing by right in commercial zones and blocks most local density caps, conditional permits, and parking mandates above one space per unit. Nashua’s proposed corridor-based density system is among the local approaches the statute may override. Developers gain a clearer path, while cities retain site review and may require traffic, water, and sewer studies.

Ford raises its 2026 profit and cash-flow outlook

Ford reported adjusted earnings of 42 cents a share and $44.89 billion in automotive revenue, then raised full-year adjusted EBIT guidance to $10 billion–$11 billion. Management credited pricing, profitable vehicle mix, and operating improvement, and shares rose nearly 7% after hours even as total revenue fell 4%. The result shows disciplined mix can protect profit when unit volume and revenue soften.

Seagate’s cloud-demand outlook sends shares 8% higher after hours

Seagate reported $3.6 billion in quarterly revenue, $1.1 billion in free cash flow, and 34% full-year revenue growth, crediting robust cloud data-center demand. Its next-quarter revenue and adjusted earnings forecasts beat analyst expectations, and the stock rose 8% after hours. This is practical evidence that the AI buildout is producing demand and cash beyond GPU makers, though after-hours prices can change before Wednesday’s open.

MCP’s largest rewrite makes remote tool servers stateless

The July 28 MCP specification removes the required handshake and protocol session, so remote servers can run behind ordinary round-robin load balancers. It also adds MCP Apps, reshapes long-running Tasks, strengthens authorization, and expands tool schemas. Existing systems do not switch automatically, so builders should test SDK upgrades and code tied to sessions or old task behavior.

Coding-agent field report makes verification the new bottleneck

OpenAI reviewed eight scientific-software projects that used Codex alone or alongside Claude Code for maintenance, migrations, optimization, and rewrites. Agents accelerated scoped engineering work, but they could not reliably judge scientific validity and sometimes sounded confident when wrong. The durable builder pattern is explicit acceptance tests, staged changes, and one named maintainer after the agent finishes.

Moonshot releases Kimi K3’s full weights and technical report

Moonshot released the full Kimi K3 checkpoint under its own license Monday. The model has 2.8 trillion total parameters, activates 104 billion per token, and supports a one-million-token context window. Most teams cannot host a model this large, but the release enables outside testing, private deployments, and new price pressure on closed APIs.

Cracker Barrel names David Deno CEO after a bruising brand-reset year

Former Bloomin’ Brands chief David Deno will replace Julie Masino on Aug. 10. The change follows rebrand backlash, lower traffic, asset sales, and pressure to restore profit without stripping away the brand’s identity. Operators should read this as a reminder that visual changes, menu work, guest trust, and balance-sheet choices must support one clear promise.

Church’s ties restaurant scorecards and simpler prep to $55,000 more unit profit

Church’s says its turnaround lifted average franchisee sales by more than $200,000 and profit by more than $55,000 per restaurant through a store scorecard, simpler back-of-house procedures, menu work, and remodels. The chain reported 6% same-store growth and 7% traffic growth in 2026, while a new minority investment will accelerate company-store renovations. The useful operator lesson is to fund expansion only after measurable food, cleanliness, hospitality, and prep standards are producing better unit economics.

Rafaela’s grand slam gives Boston its 18th win in 20 games

Ceddanne Rafaela hit his first major league grand slam as the Red Sox beat the Athletics 4-2 after going hitless for five innings. Boston moved to 55-50, while Payton Tolle struck out seven and new arrival Curtis Mead’s wrist X-rays were negative. The streak is real, but the looming trade deadline and Mead’s day-to-day status still shape the roster decision.

Red Sox American League odds collapse from +8000 to +850

Boston’s recent winning streak cut its BetMGM American League price from +8000 to +850. Half of post-break money at the book has backed the Red Sox, according to a trader. The move reflects real momentum, but the new price offers far less upside and still assumes a low-power offense can sustain its run.

Repeated downpours create an isolated New Hampshire flood risk through Thursday

Scattered storms can still bring torrential rain and gusty winds Tuesday evening, followed by heavier rain Wednesday and unsettled weather into Thursday. Repeated downpours over the same area could cause isolated flash flooding, especially in poor-drainage and low-lying spots. The risk is localized, so operators should follow local warnings rather than assume all of southern New Hampshire will flood.
