Maybe. On Android, iOS, Firefox extensions, and many websites, you can't give permission for one thing without giving permission for everything. Or those "I accept cookies popups" -- until recently, you couldn't choose which cookies you wanted to accept, so either you accept tracking cookies in order to use basic functionality, or you head elsewhere. The application developer could be a good citizen and request on th…

I would argue that it failed to be successfully demonstrated with uBlock, as my premise was about regular users, not consumers with technical skills to go into browser settings.

Fair enough. I'm not aware of any studies on the UX success or failure of uBlock, I just know that it's (at least kind of) popular.

I am very happy that the web has no more APIs. I'm already tired enough of telling my browser that I don't want any website to send me notifications, to access my location, to access my camera, my microphone. And God knows what goes behind my back. Enough is enough!

I remember reading about USB access at one point, that'd be fun!

Really doubt you are legally allowed to use GPS based speedometer in place of actual one either.

Ok, but it's more accurate than the spedometer in my higher end car, which seems to be off by about 4.6mph lol. I was always wondering why those speed radar things on the side of the road that tell how fast you are going (usually in residential neighborhoods) were consistently showing me going about 5mpg slower than my car was indicating until I checked with my phone gps. So, I was consistently going about 5 mph unde…

All speedometers are regulated into slight plus from the wheel speed. This ensures you are not speeding unaware of it.

Aside from the calibration issue, GPS has poor or no coverage in tunnels, underpasses, mountainous areas and between dense urban high rises. Prone to EM interference too. Not a good thing for safety critical device.

Are there jurisdictions that require a speedometer, vs requiring people to obey speed limits?

Most places I know about require that all driving-related equipment your car is fitted with should work. E.g. it's fine if your car has no ESP or ABS, but if it does it has to work. If your car had no turn lights or seatbelts originally it passes the inspection, but of course not if they simply don't work.

So perhaps if you drive early model Ford T no speedometer is fine, but otherwise seriously doubt it.

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…

If it has offline support you can simply save it to your computer, or use "add to desktop" in iOS and Chrome browser.

Exactly. If more people's reaction, instead of searching an app store for a privacy respecting screen light, was to sit down and write: let on true; and were able to easily upload it somewhere on a phone and run it locally from a shortcut on the screen. We'd have hacker culture encouraged right there.

You can do that with mobile-web-app-capable and add to home screen on both ios and Android. No address bar and it looks like any other app. You need to host the site though.

Running it from file:/// of the phone's local filesystem could be more hassle-free. Not sure if it would be bookmarkable, but I don't see why not. I don't have access to a smartphone to try.

Upload? Come on, just load it as dataURI, bookmark it and you have offline "application" at your disposal. And as a bonus, here, have this "distributed app store" you can even print on paper [1]. [1] http://zxing.org/w/chart?cht=qr&chs=350x350&chld=L&choe=UTF-... i.e. QR-coded dataURI document data:text/html;charset=utf-8, Screen light

This is great! I added some text to it to make it more "user friendly" and compressed it a bit so that it fits inside a tweet: https://mobile.twitter.com/T0astBread/status/109220433722755... data:text/html, Screen Light Screen Light Turn your screen into a light source Tap to toggle Source

Yes, such "offline bookmarked dataURI applications" are great, underappreciated and ancient things. Sadly, current trend in modern browsers is to suppress them in sake of security, because in the past some crooks misused them them. Currently you cannot even link to them like you could in the past; anything other than direct navigation from bookmark or URLbar results in better case in blank screen, in worse is silently blocked. For example in the past you could redirect to them, or make datauri editor that encoded itself into another datauri, or both [1], but now you can not [2].

My iPhone 6s doesn’t like this QR code, it just says “No usable data found”.

The built-in QR detector is very finnicky/odd, apparently it just assumes every payload is an HTTP URL, nothing else works even remotely. Other applications work much better for that, though they may or may not recognise non-http URIs e.g. here scanbot just displays the textual content and you're on the hook for copy/pasting it wherever you need.

Yes, I had no luck even with QR reader integrated in Nightly Android [0].

Sadly, copypasting resulting URI as plaintext is most probably the only option for modern browsers, because any other way of top level frame navigation to dataURI document is blocked. (Besides existing bookmark, that is.) I keep forgetting this, sorry for hurried "in theory it must work great" shout out.
