Working on @v8js

ECMAScript grammars might look scary at the first sight - the latest episode of my blog post series is here to help!

@vinii_joga10 The comment was renamed recently; the previous version was "//# eagerCompilation=all". That said, IIFEs are already eager compiled (but their inner functions aren't). (Not sure what the native code IIFE means tho.)

Boost your JavaScript parsing & compilation! 🚀 Learn about the new per-file explicit compile hints in V8 (per-function coming soon!): https://t.co/K8nsW8NveZ #javascript #v8 #performance

[Marja Hölttä @marjakh]

@vinii_joga10 Excited to hear how / if it works for your in Node! (Stay tuned for the per-function version too!)

[Marja Hölttä @marjakh]

@vinii_joga10 You'll need to pass the kFollowCompileHintsMagicComment compile option: https://t.co/ISJ8A3x8yN (Note for the future: at some point this will become the default and we'll remove the compile option.)

I wrote about side effecting a deopt in javascript:

well, @v8js in particular but all engines probably do this

@GavinRayDev @v8js Have you tried using Atomics.wait or Atomics.waitAsync? I hope this post is helpful: https://t.co/Bb8pUy6dTw

@MaxFragg I don't have it anymore :(

[Marja Hölttä @marjakh]

Told my 7yo that she's allowed to try to bypass the parental controls on her mobile phone. I might regret this later!

[Marja Hölttä @marjakh]

I also tried to convince her that she needs to tell me after she succeeds, but she wasn't fully convinced yet. Am I raising a black hat?

[Marja Hölttä @marjakh]

She's pretty close to having my unlock pattern but can't get it quite right. After she manages that, I'll change it, and the next time she'll probably try to get my Google account password (our home opsec is not great yet, it's doable). When are keyloggers age appropriate?

If Elon asked me to share my most salient patches, I'd include this "security bug fix by deleting 10 characters" https://t.co/MwqdA9WBJl (that's the whole fix).

@robpalmer2 @_shu @TC39 @v8js @camillobruni @bmeurer @dinfuehr @nimODota cc @jameslahm2 (that's wangao's Twitter account) - thanks for implementing this!

[David Schütz @xdavidhu]

I found a vulnerability that allowed me to unlock any @Google Pixel phone without knowing the passcode. This may be my most impactful bug so far.

Google fixed the issue in the November 5, 2022 security patch. Update your devices!

In this post @mmolgtm goes through the details of CVE-2022-1134, a type confusion in Chrome, and shows how to gain remote code execution in the Chrome renderer using this bug. https://t.co/T4643hqF08

Why passing small objects by value instead of reference is often faster, explained with my cats 🐈🐈‍⬛

[Ben L. Titzer @TitzerBL]

Aye, for my part, I've been a hater at turns. PLs are amazing tools--animated mathematics! We shouldn't let our dark instinct to scorn other people and form tribes ruin this journey of shared discovery. https://t.co/qAkbm9O0RB
