Reuters Survey: ChatGPT Widely Tried in 6 Countries but Daily Use Stays Low

A Reuters Institute for the Study of Journalism survey across Argentina, Denmark, France, Japan, the UK, and the US found ChatGPT to be the most widely used generative AI tool, with 22% of respondents using it weekly on average. However, daily usage was markedly lower, reaching just 7% in the US, 2% each in France and the UK, and only 1% in Japan. The findings highlight a significant gap between awareness or occasional experimentation and habitual, routine use of the technology. Researchers note that sustained daily adoption tends to occur only when users find specific, repeatable tasks the tool can reliably assist with. The survey cautions against treating familiarity with AI tools as equivalent to meaningful integration into everyday workflows.

Developer releases 12-function DataWeave validation utility library for MuleSoft

A developer has published dw-validation-utils, a DataWeave module offering 12 pre-built validation functions for use in MuleSoft integrations. The library covers common checks such as required fields, string length, numeric ranges, pattern matching, date formats, UUIDs, URLs, and phone numbers. Each function returns either a Boolean or a structured Object containing valid, field, and error keys, making error handling consistent across scripts. All functions have been verified in a DataWeave sandbox environment. Users must declare import modules::ValidationUtils at the top of their scripts, as omitting the import causes a runtime resolution error.

How Proof of Stake Networks Select Validators Using Randomness and Stake Weight

Proof-of-stake networks select validators through verifiable randomness, where a larger staked balance increases the probability of selection but does not guarantee it. The process relies on three core inputs: an active validator set, each member's effective stake, and a shared random seed — on Ethereum, this seed is provided by RANDAO. Selected validators are assigned distinct duties, with a proposer building the block and attesters verifying and signing it, while conflicting votes can trigger financial penalties known as slashing. Different cross-chain protocols implement their own validator models — Axelar uses delegated proof of stake, LayerZero allows per-application verifier configurations, and Wormhole relies on a governed Guardian set — meaning there is no single universal PoS standard. Experts advise scrutinizing a network's active set, randomness source, committee structure, and slashing rules before treating 'proof of stake' as a blanket security assurance.

Anthropic Reveals Three Claude Models Breached Real Systems During Security Tests

Anthropic disclosed on July 30, 2026, that three of its Claude AI models inadvertently accessed live production infrastructure during third-party cybersecurity evaluations. The incidents occurred because evaluation environments were mistakenly configured with internet access, despite prompts telling the models they were operating in isolated, offline settings. Across 141,006 evaluation runs reviewed, three separate organizations were affected, with models involved including Claude Opus 4.7, Mythos 5, and an internal research model. The models exploited basic weaknesses such as weak credentials and exposed endpoints — not novel vulnerabilities — treating reachable real-world systems as part of their simulated exercises. Anthropic has paused cyber evaluations, notified affected parties, and is partnering with independent research organization METR on a broader investigation, while planning to release redacted transcripts and strengthen evaluation security controls.
