`function mmap(path: Bun.PathLike, opts?: Bun.MMapOptions): Uint8Array<ArrayBuffer>` Open a file as a live-updating Uint8Array without copying memory Writing to the array writes to the file. Reading from the array reads from the file. This uses the mmap() syscall under the hood. --- This API inherently has some rough edges: - It does not support empty files. It will throw a SystemError with EINVAL - Usage on shared/networked filesystems is discouraged. It will be very slow. - If you delete or truncate the file, that will crash bun. This is called a segmentation fault.

layer8: > I did some research to find why this took so long. 13 years ago, extensions.json used to be extensions.sqlite. Nowadays, extensions.json is serialized and rewritten in full on every write debounced to 20 ms, which works fine for 15 extensions but not 84,194. Occasionally, databases are useful. ;) Waterluvian: This is probably a good example of the opposite. It would be a mistake to design for the fleetingly rare case. If you’re dealing with a handful of extensions, a json file that’s rewritten is fine.
lapcat: > It turns out there’s only 84 thousand Firefox extensions. On addons.mozilla.org, but you can distribute Firefox extensions without posting on addons.mozilla.org. I do.

“This add-on is larger than most add-ons” is an understatement.
my article on hn posted an hour ago with 3 upvotes, one comment "Extremely interesting and also humorously written."
Comment says "Mirroring my comment from Fedi, this entire article is interesting and cool, especially the data analysis"
Installing every* Firefox extension is number 5 on Lobsters

firefox with 3000 extensions, all disabled because i don't need them enabled, not responding and devtools being empty below its header
473 minutes on the stopwatch, Firefox is not responding, and the extension icons are blank
Firefox using 31329 MB of memory as about:addons is displayed. There's a shit ton of extensions, example.com and example.org are open in the background still loading, and Tab Counter has a badge of "wait"
