Too late to edit so replying to myself. I was mostly wrong. The GPS limits are much higher than I thought, and accuracy of INS is too low, although I still think that limit is artificial.

I would argue that most websites have a lifetime similar to the components :). For the ones that don't, backwards compatibility on the web is amazing, only thing to worry about is security vulns

Easy to cause it by combining bootstrap components and JQueryUI. In React you can "scope" a components CSS so none of the styling leaks out

It's okay, I was wrong about what the limits are too. They've been increased a lot

Java Applets were before their time. It took JS/HTML the good part of a decade to catch up functionality and performance-wise

Possible maybe but unusual. 99% of ham is narrowband, GPS is spread across a megahertz. Somebody goofed and made a TV tuner chip that could be used as an SDR at that sample rate, and I'm sure the powers that be arent happy.

You might be right but I have doubts. Most weapons are INS guided despite the long fly times of cruise missiles etc. ITAR has a massive chilling effect on development, I wouldn't be surprised if we had error rates of less than a meter

Fibre optic gyros can be miniturized to millimeter dimension, if it wasn't for ITAR. High end civilian IMU's typically use mechanical gyros which have been obsolete for decades. Also, a phone isn't typically moving constantly

The limits are higher altitude and faster speed then you've ever been. If the Concorde was around you would see it firsthand. Weapons would be worthless against first world defences at airliner height and speed. Gps receivers shut down

Yes. Look at the ham hobby, hardly any of them can pick up GPS signals, despite the technology being literally everywhere

The real answer is star navigation at night and interial + sun guided during the day. Phone hardware is perfectly capable but ITAR says otherwise. There's a reason why every legal GPS receiver shuts down after altitude or speed limits

Exactly why I said 20 years! The hopeless diamond. I would still delete this if real. Even though you didn't give away anything of substance it's enough to be marked a traitor

All satellite nagivation systems are trivially jammable. They use DSSS to spread out codes and resist jamming but signal levels are still so weak at the surface it's trivial to block. Most phones are compatible with GPS(US) +Galileo(Eu

Not surprised, but you might want to delete this. If there's nothing on the internet but this post I would keep quiet. I use long lasting throwaways but it's trivial to find me. If nobody has heard about something you haven't

Not a big believer in traditional conspiracy theories. But, there's a lot of evidence that the US military has a lot more than they let on. I mean, GPS, the internet, strong encryption (look up history of DES). Much of what we take for

Devil's advocate, but I have a feeling black people, at least in the US, are driven to look "hipper" from systemic racism. When society is generally more suspicious and condescending it makes sense to pay more attention to ho

I'm talking about my code specifically. With React I can pull in a massively complex UI component in few lines. The complexity is shifted to the library that hopefully has thousands of users so is mostly bug free. It simplifies my code

IMO, Google put a new stage on embrace extend extinguish I call "neglect". Make everything open source and nice, then continue to update G specific functionality by simply not maintaining good support for anything else. Google pro

It's not about how complex the component is. In my experience what matters is how easy it is to use. With React it's easy to build a world in a teacup, and that's mostly a good thing. For "regular CRUD developers",

Development with React is becoming similar to old school event driven desktop apps, thankfully. If I want a fancy drop-down with accessibility support and theming etc, there's probably 50 different libraries with components I can pull

Angular's learning curve is the worst I've ever seen. We mostly use it because "Enterprise" but I prefer React when we get permission for that reason. Too much abstraction, too much magic. It's possible to do just a

Transpiled JS specifically. JS is the only popular language with a great deal of differences between versions and runtimes, mostly due to rapid improvements. If you use "vanilla" ES2017 without transpilation you're in for a d

Typescript is super easy to bring into a project. Just rename .js to .ts and turn the validations off. Any valid JS is also valid TS. Build step is one command to run tsc. You can turn things on slowly as you refactor into idiomatic typescr

It's extremely easy to use React in small parts of the page and spread it out over time. It's a couple lines of code to init React in a div and fully supported. You can even communicate between React bits spread across the page. R

You generally don't mix react and JQuery. The event system + JSX makes jQuery obsolete. Having worked in complex interactive React/Angular apps as well as ones using JQuery, nobody would ever offer me enough to use JQuery again fo

Haven't looked at Babel's, but the output from Typescript is human readable and not much bigger than the original. The more polyfills (lower your target lib aka ES3 vs ES2015) The bigger the output. Even targeting the oldest crapp

I don't even bother with vanilla JS. Babel and Typescript let you magically use the latest features without caring about compatibility at all really, except CSS

by thermodynthrway 8y ago
If you have even medium complexity you're better off using something like React with Babel or Typescript. Much more sane way of event handling than JQuery, and no mucking with HTML by hand. I agree with JQuery for the most simple sites

The worst I've seen is that Google serves an ancient version of their homepage to Firefox mobile for "reasons". With an extension to spoof useragent to Chrome, you get the regular page and it works fine
