Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

One heap per type.

Bun, JavaScript, and TCO
To use this in Bun, you’d have to start Bun with the environment variable “BUN_JSC_useDollarVM=1” and then $vm.createBuiltin(mySourceCodeString)
When using this intrinsic, if any of the arguments are incorrect or it cannot otherwise enable it, the entire process will probably crash. In debug builds of JSC it will have a nicer assertion failure but that is not enabled in release builds
Example code: https://github.com/WebKit/WebKit/blob/17351231b4dedb62d81721...
also happy to answer any questions about Bun

Show HN: Rem: Remember Everything (open source)
Ah, good, let me introduce you to the wonderful world of the Chrome Devtools Protocol! (fka Chrome Remote Debugging Protocol)
I love this API for almost everything browser related. I built my RBI product atop this (BrowserBox: https://dosyago.com), and I think it's a drastically underrated API.
Also, it works out of the box in Edge, Brave, Chromium, and many parts of CRDP are supported by Firefox and Safari^1

It is different. The cross-site navigation flag is a couple of years old. It was enabled by default for iOS in November 2018 for example https://github.com/WebKit/WebKit/commit/e191fc8c412850cb9fd0...

Show HN: Firefox add-on to open YouTube videos in alternative front ends
> That's excessive scope creep. Adding site-specific workarounds for some sites feels uncomfortable.
Not to Google and its fellow corporations apparently.

They have site-specific fixes for their own sites. Why can obviously apply the exact same strategy to dealing with every single website out there. If a website is broken or generally annoying to use, just fix it by providing a site specific version of the browser.
> Who decides what websites get "fixed", and how?
Whoever develops the browser or its extensions. Arguably the whole of uBlock Origin and its filter lists is just a database of site specific fixes. If people can maintain an extremely huge list of advertisers and blockers for every website out there, surely they can maintain something like this too.
> Also, remember how Mozilla is funded.
I remember Mozilla has about a billion dollars in the bank. Who cares about their Google funding? I doubt they're gonna drop them anyway. I bet they pay them just to ward off risk of antitrust lawsuits.

Problems with Firefox non snap versions on Ubuntu 22.04?
Next time, send a SIGABRT to the main process (kill -6 $(pidof firefox)) and use the resulting backtrace (you will find a link to the crash report in about:crashes) to file a bug. A performance profile could be useful, but you'll need to know first what to capture. This seems like a graphics issue, so try the Graphics preset. Share a link to your report.

Why Spidermonkey is way slower than V8 or JavaScriptCore?
Please file bugs with performance profiles to help investigate things. Firefox devs need good info, and it's not always easy to get it. It could be anything from some optimizations not being implemented yet, to garbage collection taking place at bad times, to sites simply running different code on Firefox (yes, really, I see that in my webcompat work).
- Firefox twice as slow as chrome

Opening new YouTube tabs in Firefox is harder on CPU than other browsers.
If it is not too much trouble do you think you could capture a profile of you loading YouTube? https://profiler.firefox.com/

Video playback problems
I'm not sure either. It might be an external application interfering. See if this article helps. If this is a new issue, you could try to use mozregression to find which commit broke it and file a bug. If you do file a bug, make sure to include a performance profile captured while reproducing the issue. Share a link to your report if you do.
