Mixxx is excellent and has pretty wide hardware support.

FYI the "limited" functionality of Rekordbox can be hardware unlocked with some Pioneer controllers.

There are quite a few DJs that use Ableton for DJing (or hybrid sets). Of course, Ableton wasn't made with DJing as its main function in mind but you totally can use it for that purpose and (with some tweaking) do everything and more that would be possible in a dedicated DJing software (like Traktor or Rekordbox or Mixxx)

I’ve used Mixxx a little bit and have been surprised how capable it is. It’s an open source project and is free to download: https://mixxx.org/

Mixxx (you already mentioned this; it's certainly a great piece of free software to test the DJ waters with and works with a lot of gear).

Alternatively, you can also use Mixxx with the S4 MK2. Mixxx is free. But instead of a Traktor control vinyl record, you'd use Serato timecode instead, as stated in the docs.

If the device is class-compliant, i.e. it follows the generic USB spec and doesn’t need drivers installed, it can work under Linux. However the free software you get with the controller (Serato, Rekordbox, Traktor etc.) won’t. The alternative is to use Mixxx. It’s free and open source. You can check their controller support. https://mixxx.org/

If you don't like any of those, aren't you glad you didn't spend the money to find out the hard way? There's more DJ software than those two, so try out these as well: Traktor Pro 3, Virtual DJ, DJUCED, or Mixxx.

Well, you could try using the Internet Archive's Wayback Machine:

Link to website or name of cookbook (note: export a PDF or MP4 to save the original website or video tutorial in case it disappears, also use archive.is & archive.org/web for older recipes that aren't available anymore, like this one)

If you put the link I put above in the following page you can get to a saved version of it https://archive.org/web/

Not sure if it’ll help with this, but https://archive.org/web/ aka the Wayback Machine is good for looking up old versions of websites.

Yeah, the internet already allows you to view any website on any day in history so I still don’t know why that book exists.

yeah you can, https://archive.org/web > scroll down to 'save page now'

Not really, sorry. The best you could do is pop the URL to your bookmarks into the Wayback Machine and see if your bookmarks page was ever captured. Then you could compare your existing page to anything the Wayback has. However, it’s unlikely they would have captured all your bookmarks, or captured them recently, if they ever did.

Accounts you delete/make private may still be viewable via the Wayback Machine. Search it for any URLs related to your accounts, and if they come up, you can follow the steps here or send a GDPR notice similar to how this person did to have them removed from the archive.

Maybe try the Wayback Machine at Archive.org if you have the playlist URL? https://archive.org/web/ I'm not sure it archives that type of thing but worth a shot. Otherwise I'd say start a new playlist asap while your memory is fresh and try to back up the list in a 2nd location somehow (even if it takes a lot of effort, like typing it all out).
