A single ring, a hang-up and a foreign number in the call log—often +355, +225 or +234—is bait. Calling back connects you to a premium-rate line, with a cut going to the fraudster. The Guardia Civil has warned about wangiri since at least 2016; Maldita.es compiled its alerts in June 2022. The risk is billing … Read more
Headphone safety is now a software issue as much as a hearing-health one. The World Health Organization and European regulators converge on a simple weekly budget: 80 decibels for 40 hours per week. Above that, the safe allowance collapses. At 90 dB, the WHO estimates four hours; at 100 dB, about 20 minutes. Since most … Read more
At checkout, a new phone often comes with an “all-risk” insurance offer. The deciding question is rarely asked: would the policy pay if the handset vanished from a café terrace table while you looked away? With many policies, no. Robbery and theft differ: force, violence or intimidation against a person is treated separately from a … Read more
OpenAI and Georgia Tech researchers asked a latest-generation open model for co-author Adam Tauman Kalai’s birthday, adding one condition: answer only if you know.

That example opens Why Language Models Hallucinate (September 2025), which says the problem comes from text-prediction training and from … Read more
A private account narrows visibility; it does not erase you. Instagram and TikTok offer a single toggle, Facebook demands post-by-post audience management, and all three leave a public-facing core that anyone can see — even without logging in. Instagram and TikTok: one private-account switch; Facebook relies on per-post audiences and a bulk “Limit Past Posts” … Read more
Deleted files rarely disappear the instant you hit the button. On phones, computers and cloud services, most items sit in a trash or recycle bin with a fixed expiry date. Once that window closes, a backup is the only dependable route. On modern solid-state drives, even specialist recovery tools often have little to work with, … Read more
An unused gym membership, a shocking electricity bill, a debit from a firm you have never heard of: for any direct debit, you can ask your bank to send the money back, and the law gives the bank a deadline to answer. The rules come from Spain’s Royal Decree-Law 19/2018 on payment services, which transposed … Read more
Using a fingerprint or face to open a banking app feels high-tech, but the bank never sees either. Your phone compares the scan with a template in an isolated chip and tells the app only yes or no. The real weak point is the handset passcode. This guide is for daily bank-app users who want … Read more
Western Australia is seeking a partial refund of the A$166,000 it paid Deloitte for a 219-page cost-benefit analysis of a three-university merger. The report has misattributed references, repeats 55 times a Curtin name unused since 2010 and contains arithmetic gaps of A$260 million and A$311 million. Its strangest flaw: a compliance section claiming no AI … Read more
On 22 October Science published the peer-reviewed paper in which Microsoft says DxO — the Diagnostic Orchestrator announced as MAI-DxO — gets 83.2% of 304 New England Journal of Medicine cases right, against 36.1% for generalists. For emergency admissions the figures are 80.3% versus 46.8%. The paper is public, peer reviewed and explains its method. … Read more
