10.1 was released in 2014 and reached EOL in 2016. The screenshot appears to show a 10.1-p45 kernel that was built from December 2016 sources in September 2019, at a time when the latest release was 11.3. However, the Subversion revision number in the screenshot (r272678M) does not match any point on the stable/10 or releng/10.1 branches. To get that uname line, assuming neither the version string nor the screenshot have been manipulated, you'd have to have checked out the head (development) branch from Subversion, synced it to r272678¹ (11.0-CURRENT, October 2014), then replaced some or all of the tree (but not the Subversion metadata) with the tip of the releng/10.1 branch before building and installing a kernel in 2019.
The "M" at the end of that revision number suggests a "modified" tree, meaning they had their own patches that were not part of the upstream repository as well.
Incorrect. They default to zsh for interactive use, but their /bin/sh is bash 2. They also ship a copy of dash, but it's not sufficiently POSIX-conforming to replace bash.
Huh weird, I remember many years ago getting a notification in the terminal that bash would be deprecated so I assumed that would have happened by now. I no longer use macs so I wasn't up to date, sorry.
Three out of four aren't even companies. SUNET is the Swedish NREN, NetNod is a non-profit that manages Internet infrastructure services (like DNS and NTP) in Sweden, IIS is the non-profit that manages the Swedish TLDs.
Feel free to substitute my use of the word "company", with "company / organisation / foundation". Plus others I'm surely forgetting.
I meant 'company' in the sense of a legal entity, probably paying some kind of tax, probably having to register/file their accounts every year. Here in the UK, all of these various different types of 'companies' all have to register with Companies House, and file tax returns to HMRC. 'Company' is the overarching legal term here.
— But sure, my bad: the post I was replying to actually used a term that is arguably better, 'organisations'. And I should have used that.
But my point still stands, whether a private limited company, or a non-profit of some kind, or an organisation, or a foundation, or a charity, or whatever — they're all legal entities of some kind — and they're all able to fund anything they please, if they see value in it.
- NetNod is actually a private limited company according to Wikipedia [1]. Corporate identity number: 556534-0014.
- Swedish Internet Foundation, formerly IIS, have corporate identity number: 802405-0190 (on their website [2])
- Sunet is a department of the Swedish Research Council, and uses the Swedish Research Council’s corporate identity number 2021005208, according to their website [3]
So they are all registered with the Swedish Companies Registration Office. Which I assume is their equivalent of Companies House here in the UK.
Maybe if you still think that they're not 'companies' — of some kind — then perhaps take it up with the Swedish Companies Registration Office! ;)
The macOS userspace was never forked from FreeBSD or any other BSD. If anything, it was forked from NextSTEP. In actual practice, it is a collection of individual components taken from a variety of sources. When development of Mac OS X began in 1999, most command-line tools and a large part of libc were derived from either NetBSD or OpenBSD via NextSTEP. Over the years, there has been a shift toward FreeBSD. Apple maintain a collection of GitHub repositories of their Open Source components where you can see the evolution from one release to the next. Most of them have XML metadata indicating the origin of each individual component.
Info-Zip Unzip 6.00 was released in 2009 and has not been updated since. Most Linux distros (and Apple) just ship that 15-plus-year-old code with their own patches on top to fix bugs and improve compatibility with still-maintained but non-free (or less-free) competing implementations. Unfortunately, while the Info-Zip license is pretty liberal when it comes to redistribution and patching, it makes it hard to fork the project; furthermore, anyone who wanted to do so would face the difficult decision of either dropping or trying to continue to support dozens of legacy platforms. Therefore, nobody has stepped up to take charge and unify the many wildly disparate mini-forks.
