That depends. You don’t have any helpful commit logs or even changelogs. But if you arrange e.g. the XNU releases in the form of a reasonable graph and import them into git that way, you can get some telling diffs, on the command line at least. GitHub is not being very helpful here because it does not allow you to diff arbitrary tags and revisions from a repository. But GitHub is still a place where people find and look for code.
After watching their promo video at the top of the page, I'm left wondering two things:
- If the machine takes away all my liberty (I cannot use it on my fruit and vegetables) and even their packs need to be refrigerated and stay good only for 8 days, can't I just buy the resulting juice and put it in my fridge? (If I left the bottle closed, that would last equally long). So what do I gain?
- They're using QR codes to check that I'm not using their packs beyond the "best by" date or try to trick the machine into squeezing a competitor's cheaper packs. And for that, they need a camera on the inside. And WiFi. Didn't somebody at some point notice that the way they're treating their customers is really disrespectful? This is the whole printer-cartridge-thing all over again.
Those thoughts prompted me to create https://github.com/epipping/xnu-kernel-sources-x86 (and its cousin https://github.com/epipping/xnu-kernel-sources-ppc). Maybe you find it help (please take a look at the wiki)
