The ERC-4626 vault inflation attack,
defused

Η επίθεση πληθωρισμού στα ERC-4626

An attacker deposits one wei, donates a fortune, and the next depositor's shares round to zero. A figure-led reading of the donation attack on tokenized vaults — the rounding it abuses, the worked exploit traced from t4sk's reference code, and the two virtual numbers OpenZeppelin added to make the theft a money-loser.

Do hot drinks cause cancer?

Προκαλούν τα ζεστά ροφήματα καρκίνο;

A viral chart says the hot-drink–cancer link collapses under age adjustment — and coffee is genuinely exonerated. But the headline drops the one signal that survives every control: scalding liquids and the esophagus.

An honest buying guide for a fully-offline robot vacuum in Greece — no cloud, no account, no forced firmware. The only real path runs through Valetudo on a LiDAR Dreame/Xiaomi/Eureka you root yourself, past five years of documented leaks and around an EU rulebook that is tightening but still not enough.

Does red light therapy work?

Λειτουργεί η θεραπεία με ερυθρό φως;

Fifteen indications, graded one at a time. One reaches guideline strength — and it uses a probe inside the mouth. Two more are probable. Most of what the consumer market sells is unproven, and one claim has no human evidence at all.

Less protein,
more years of life?

Λιγότερη πρωτεΐνη, περισσότερα χρόνια ζωής;

A Greek press report says a July 2026 review shows that eating less protein adds years to human life. A common counter-claim says muscle adds them instead. Both are tested here from the primary literature — and the mechanism everyone cites has a gap exactly where the argument needs a result.
