Holy crap it's scary that he's building his own speedometer like that. GPS based speedos aren't all that accurate. Ballpark, sure, but not accurate. There are also many circumstances under which GPS won't work. In many countries a car without a functional speedometer is not allowed on the road, for safety reasons.
Introduce acronyms before you use them. I'll say it again for the people in the back. Introduce acronyms before you use them.
(It means web pages that use JavaScript to gain access to some “app” features, like offline-functionality and the device sensors as shown in the blog post.)

I'd expect it to be better than the car speedo. Car speedos typically overread by up to 10%, and if you fit a non-standard tyre, they can be way off.

And many countries are authoritarian shitholes who care more about revenue generation than protecting people. People don't need a speedometer to drive safely.
Yes, they really do. Just ignoring the fact that people tend to drive faster when they don't have a speedometer, people already travel too fast for road conditions as a matter of course. Let alone the fact that at residential road speeds, the difference in life expectancy of someone hit by a vehicle drastically changes with even a slight increase in speed.
Safety checks exist because vehicles are roving machines of death driven by easily distracted people, who have a long track history of ignoring what they can't see.
Your life shouldn't be put in danger because some other arsehole decided that it's perfectly fine to drive a rust bucket with nothing more than a sheet of paper left by way of brakes, or with lights that are so badly adjusted anyone else gets blinded, or with windows in a state that someone sneezing will shatter them, or any other number of things.
But yeah, authoritarian government overreach. Sure.
What happens to your PWA page weight when you add tracking and ads to it? How do I find your ad-free hobby project in the sea of search results for "speedometer" PWAs on the open web? What makes sure you will keep paying the, admittedly modest, hosting costs for the app? I think it's great you can make "tiny PWAs" but I think the article is glossing over the incentives and discovery problem that leads to 30MB ad-infe…
Earlier quoted context omitted.
You wouldn't introduce the acronym "omg" since what it stands for is so well known. I'd argue the same is true in this scenario.
What does PWA mean? After reading some comments I guess personal web apps but I not sure.
> “surely there is a app for that!” A quick look leads to speedometer apps with ads and 30MB download weight, and simple screen light that also have ads that weight in at 5MB. I’m finally groking what rms has been banging on about for so long. It is completely unacceptable that we are running software that does this to the user. Users need to be empowered and able to run code that they can control.
Why don't browsers give us finer control over Javascript execution (eg whitelisting JS APIs)? Performance?
