Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
Jank-less computation on the browser
Fiberify breaks up big recursive computations (like diffing or merging trees) into separate chunks and schedules them to run in the browser without dropping frames.
// Lets say you want to calculate 2^n in the dumbest possible way.
const pow = n => {
let s = 1;
for (let i = 0; i < n; i++) s += pow(i);
return s;
}
// Fiberifying this just requires some well placed async/awaits:
const fibpow = fiberify(async n => {
let s = 1;
for (let i = 0; i < n; i++) s += await pow(i);
return s;
});
Fiberify focuses on maintaining responsiveness, and not completing the computation efficiently. The time required to complete a fiberified computation is usually several times higher than the direct recursive function.
