Το πρωτεϊνικό στακ, μόνο τα τεκμήρια

Whey · creatine · glutamine · EAAs — a two-tier audit of the four supplements most often stacked for muscle gain and fat loss, with effect sizes, conflicts of interest, and an honest debunk of BCAAs-as-muscle-builder.

Ethereum,
from the Yellow Paper to the Endgame

Ethereum: από το Yellow Paper στο Endgame

Gavin Wood's Yellow Paper specified a world computer as one exact equation. A decade and ~20 hard forks later — EIP-1559, the Merge, blobs, PeerDAS — almost every number has changed and the equation has not. A formal, figure-led reading of the protocol and everything that rewrote it.

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.

A robot vacuum that doesn't phone home

Μια ρομποτική σκούπα που δεν «τηλεφωνεί στο σπίτι»

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.
