Yep, and they use Courgette for all of their Chrome/Chromium updates. It's why no one ever sees long "Downloading update..." progress bars in that browser anymore. 100KB binary diffs are typical. Blink (no pun intended) and you'd miss the download.

Result! Thank you. Skimmed the landing page, original paper. Courgette infers program's structure for smarter diffing. My half-baked notion is somewhere in between.

Check out IntelliJ's binary patching - it might be closer to what you want? It's based on bsdiff.

The actual binary patching magic happens here: https://github.com/JetBrains/intellij-community/tree/master/...

Since the last Catalina update (10.15.4) Firefox is almost unusable for me, whereas it was buttery smooth before. There are constant multi-second freezes and when I switch tabs I often see a gray loading screen before the content shows up a few seconds later. Never saw that happen before. Maybe it's just a coincidence and has nothing to do with the Catalina update, but I am interested whether other people experience…

Follow up: The latest Firefox update seems to have solved the issue. So far.

Battery health management sounds great! I wish there was a way to customize this, though: Thinkpads have (on Linux) allowed setting thresholds for "charge only when less than" or "charge only up to" for many years now. Given that such primitives must also exist as part of 10.15.5 now, I hope that somebody will figure out how to modify the default behavior.

I'm glad that sort of thing doesn't exist on macOS by default, though third-party tools have existed for a while. I'd much rather the system figure out the charge threshold dynamically based on all sorts of variables like temperature, battery degradation level, expected imminent usage (learn from my own past usage on-device -- coreduetd) and other variables they can take into account. Which is what it does.

The cynic in me strongly suspects that planned obsolescence is one of these other variables.

I am constantly gobsmacked by how slow point release upgrades are. On Ubuntu, it takes virtually no time and doesn’t interrupt my workflow.

There are plenty of disruptive ubuntu upgrade issues, for example for almost 5 years (through 12.04 to 16.04!) if you installed on LVM volumes your /boot partition never cleaned up old vmlinuz and initrd images, causing dpkg-reconfigure to fail, leaving dpkg completely broken. Operating systems are hard.

Sure, that’s a hard failure, I was talking about the average speed to install an update.

Since Catalina I have been getting daily freezes, where the entire operating system locks up. I can still move the cursor around and audio keeps playing as well, but everything else is completely frozen. Once in a while the freeze lasts so long the computer crashes resulting in a crash report: Termination Reason: WATCHDOG, [0x1] monitoring timed out for service Termination Details: WATCHDOG, checkin with service: Win…

I have the same issues !! I have a couple of raid drives and third 10T - a second dell monitor connected to my iMac pro 18 core....If I loop a time line in fcpx, loop audio in Logic, run the Black Magic disk test my system will freeze, still playing audio then give up the cursor then hang fully and crash = in the spin dump we get the watchdog time out !!!! I am on 10.5.5 looks like its some kind of GPU issue

For anyone else having this issue, the fix for most people seems to be disabling Power Nap[1], which is enabled by default when you're on AC power. Can confirm that this worked for me personally. Disappointed to see no mention of fixing this bug in these release notes, however. [1] https://discussions.apple.com/thread/251274321?answerId=2526...

Didn't work for me sadly - if I leave my MacBook docked it crashes every night even with PowerNap off :/

Same.
