There's a ZA company doing something similar: https://root.co.za/


There's a common belief among motorcyclists that having loud exhausts help alert other car drivers of their presence, making them more visible on the roads. There are various arguments in favor and against that notion, but if it's getting you to notice them I guess it is better than nothing.


I never believed that. I was an avid motorcyclists for decades and spent lots of time around riders of loud pipe bikes. If safety was what drove them to straight pipes, then I would expect those concerns to carry through with the rest of their gear.


I read somewhere that statistics actually suggest the opposite - that bikes with loud pipes are more likely to suffer a serious accidents and injury. I suspect that's because the type of bikers that have loud pipes are also the ones riding aggressively, overtaking frequently, weaving between traffic lanes, etc.


As a motorcyclist & car driver, what I've observed is in a car you can hear loud pipe bikes- but only when they are in front of you, i.e. with the tailpipe pointing at your face. Behind or beside you- in other words, in your blind spots- don't hear a thing.


I used to have a ZX-10 with super loud exhaust (apparently a previously owner amateur raced it) and other drivers would definitely know when I was around them. People don't always see motorcycles but if they hear you they tend not to pull right out in front of you in my experience. It also worked a lot better than the horn to get people's attention, little beep vs. loud roar.

Not that I'm advocating for loud motorcycles, mufflers exist for a reason...that bike would set off car alarms while just idling past in parking lots which was kind of annoying.


It's ironic you should mention apps like Facebook and Instagram[1]. They use React Native.

But they DON'T USE React Native in the main feeds of either Instagram or Facebook. You know, where users spend all their time and performance matters.

You linked to a post about a bunch of settings/picker screens in Insta. On the FB side, my understanding is that only the Marketplace tab is RN, and maybe the settings & notifications.


oh so that's why each time I reopen an instagram convo from the background, I have a blank webpage .. thanks RN !


Not to discredit, but that's a lot less significant.


Yes, hence the "hacked together in an hour" part.


You could potentially use the validation rules, and set a min length of 1.


You'd need [required] instead of [minlength] for :valid to work. The other option is :placeholder-shown, to style no-input normally, but it's newer and not as supported.


I wonder if the good old input[value=""] would work. Probably not if you have jQuery.


No, because that matches on the HTML attribute (aka the defaultValue property in JS), not on the current value of the input.


Unlikely. The only reason he was able to survive IMO is that his pilot chute deployed, slowing him down.


Survival without a chute seems to involve hitting some large object that slows you like a tree or a bendy roof.

Here's a pic of the roof that saved one guy http://cdn2.fella.com/2016/06/20151717/Magee-11.jpg
