V8 對 for-in 的最佳化

V8 引擎的人對 for-in 的最佳化寫了一篇解釋「Fast For-In in V8」,比較直接的結果就是維基百科與 Facebook 都變快了: For example, in early 2016 Facebook spent roughly 7% of its total JavaScript time during startup in the implementation of for-in itself. On Wikipedia this number was even higher at around … Continue reading

Akamai 阻擋 DDoS 能力的上限

這應該是最近在看 DDoS 事件中比較重要的新聞了,從這次的事件知道 Akamai 沒有能力擋下某種 620Gbps 以上的 DDoS 攻擊,而這是攻擊者已經有能力「示範」出來的量:「Akamai kicked journalist Brian Krebs' site off its servers after he was hit by a 'record' cyberattack」。 The assault has flooded Krebs' site with more than 620 gigabits per second of traffic … Continue reading
