Netflix's A/B testing has really screwed me in the past in terms of performance, so much so that I reached out to support to ask if there was a way to manually remove me from the testing group at that time. I'd log in, and the "new" interface throttled my 13 inch retina Macbook's CPU immediately to 100% (or more). Last time it was so bad that I stopped using Netflix on my computer until the testing stopped. That said…

You can opt out of A/B testing. Head to netflix.com, go to your account settings > Test Participation > Include me in tests and previews, and switch it off.

Wow thanks. I always seems to get screwed and placed in the B group. That or their UI is just frequently terrible.

Especially the lag that you see on some brand new cars, only BMW and Audi seem to have lag free interface, but anything else that involves touch interface is just horrid! I've recently sat in my friend's brand new Honda SUV and the interface lag is just plain silly, for a car that costs $30,000+. Why is that?

I found this advertisement from Mercedes interesting: https://i.redd.it/wwxk8nqh88ex.gif I can't speak for the quality of Mercedes interface (and this is obviously marketing for non-programmers) but LOC seems like an odd thing to be emphasising.

These things are quite random, because most likely they counted also all dependencies in - including LoC for OS kernel, all libraries, etc. And how much LoC is boost alone? :D

Because Honda at its core is not a software company?

I've worked at several companies where at least one manager/exec says "We are not a software company, we're a ___(their core product/service)___ company". If an organization creates and utilizes software as part of their ongoing concern...is at some level, a software company.

Indeed. Yahoo pretending it wasn't a software company is what lead to a billion user accounts getting compromised in the largest data breach in history.

As a programmer who strongly believes in less being more, remind me to never buy a Merc.

Believe it or not, the software quality in these things is often quite cruel, and even a mediocre javascript framework might perform awesome against it. I've seen enough things things like handcoded UI frameworks in C++ (in order to be fast), and then doing things like blocking network calls on the main thread from there.

Some newer systems are based on QT or Android. These typically have better performance, because the underlying frameworks have at least a decent design.

Everyone needs to hit 100,000 LOC this week to hit our target from marketing

I wish there were car reviews out there that take software quality in account in particular for things like lane keep assist. When I was in the market for a car the reviews that I have seen only mention if they have the feature, not how well it actually works.

Oooooh, don't get me started on DVD menu screen navigation. What shambling, drooling idiot decided that it was critical for me to watch an unskippable spoiler-rich montage of scenes from the entire length of the movie before I can click "Play Film", followed by another unskippable montage afterward? Insanity.

I love animations when they make the UI more understandable. I can't stand them when they are more than a couple hundred milliseconds though. I don't even think "synchronous" when I think of animations. That sounds terrible. If they are quick animations it doesn't seem as big of a deal as the long running ones though.
