  • Teenagers today suffer unique threats to their health and wellbeing from technology. It may be super easy for you to say “who the fuck cares about the color” but that is far from the case for US teenagers. Willingly setting yourself apart from the group in high school is a precarious move in the best of circumstances.

    And for the rest of us, this goes way beyond the color being used. The SMS/MMS fallback in iMessage offers a terrible experience for non-Apple users. Low quality media, inability to manage one’s own memeberships in groups, and no encryption. For those worried about the lack of e2ee: Android users participating in an iMessage conversation don’t have that today. You’re not losing anything from this solution.

    Legal disclosures prove that Apple knowingly uses iMessage in an anticompetitive fashion. It’s a moat to keep people from switching away from iPhone. They are leveraging their position in the messaging market to shore up their restrictive phone products. I wish US antitrust enforcement was stronger in this area but until then, I hope Nothing has great success in breaking down this illegal barrier.









  • The Nvidia thing was a subtle way to point out that you can’t “brew install” your way out of every bit of missing OS functionality. The subtly was sadly too subtle.

    “Posix” is such a trivial set of APIs that until recently Windows claimed to be Posix compatible (and basically still is???). Darwin, the MacOS kernel, lacks pretty much everything above that slim foundation. No user or network namespaces. No capabilities. Even if you switch to GNU coreutils (ls, ps, netstat, etc), you get a reduced featureset because Darwin lacks /proc, /sys, ioctls, and other knobs&levers to make stuff work the way it does on Linux. Xorg works because X11 was common across all Unixen back then. And on the built in BSD utils, stuff gets weird like ls ~/Downloads -l doesn’t work and case insensitivity leads to weird bugs in things like shell wildcards (like ls ~/downlo*/*).

    The Linux network stack is complicated because it can do absolutely everything, at insane speeds and scales. MacOS’ network features are geared towards being a laptop and not much else. I won’t defend Linux as user friendly but it’s been my daily desktop for 25 years, I guess I’ve figured it out. I use and appreciate stuff like VLANs, bridging, nftables, ebtables, etc. If you need to change behavior, there’s probably a /proc/net flag that will do it. It’s stuff that MacOS hides or simply doesn’t have.
