28 Years Later, Windows Finally Supports RAR Files

That is a lot of fluffy words to say that Windows has add support for a number of zip archives by way of a integrating the open-source libarchive project.

Also:

"But had it not been a .sea (self-extracting archive) courtesy of Stuffit, we would have been waiting well into the next day."

I don't understand how a self-extracting archive -- basically an dearchival program concatenated onto the front of an archive file so that you can just run it rather than downloading a separate program -- would speed up the download process at all.

.rar may get the headlines but I'm more excited about .gz, .7z, and the others these days. As long as it's done "good enough" it could be the end of installing 7-zip for me.

And whilst most of the Linux world has moved on to zstd...

libarchive supports Zstandard. The "other" part of the description is doing a lot of work for those that know of the many compression algorithms in use these days.
