Regardless of how you feel about hooks, they are, or are quickly becoming, the new standard for most React code, so a React tutorial obviously needs to familiarize people with them. The current tutorial is good at explaining React concepts

React by itself isn't difficult either. Anyone who has an hour or so to spare can go through the tutorial https://reactjs.org/tutorial/tutorial.html . They need to rewrite it to use hooks at some point, but it&#x27

The WSL integration is a pretty good result of that effort too.

Update (can't edit the comment on HN anymore): So I misunderstood (only skimmed through) those 2 links about desktop Firefox sideloading, they use a different meaning of that term than what it commonly means on Android. They only block

`let` instead of `var`. No need to leak the variable into the outer scope.

>Are there numbers about large amounts of sideloaded extensions causing the reputation of firefox for android to drop? I'm not aware of any, but that could be because alternative browsers are not that popular on mobile in general.

Well, their goals are clearly different. From the FAQ linked above, it is clear they want to have some control over "the experience", which is mentioned a lot. If too many users install a crappy, buggy extension that slows everyth

The basic assumption is that users are dumb when it comes to security, and if there is a way to install malware, they will be tricked into installing malware (even with no vulnerabilities in the host software itself). Especially since the

Also, commercial browser vendors were much more of a thing back then, so there was someone to complain.

The answers here seem to suggest otherwise. https://blog.mozilla.org/addons/2020/02/11/faq-for-extension... My guess would be that they'll try to make it curated-only unless users complain too much.

In such a manual workflow ( "you can SSH a file into a server" ), you still have to setup at least URL rewriting in nginx for any PHP app using routing (which is basically everything using any PHP framework or micro-framework). Pl

Can't Apple push silent code updates to specific phones? That would mean they can access that data whenever they choose to. Even if they don't do it right now, they retain that ability.

It is still missing semantic highlighting (e.g. a local variable has a different color than a function parameter), although looks like things are finally moving on that front. https://github.com/microsoft/language-serve

But you don't need to have a final design straight from the beginning. You can start with only what you need right now and evolve the types/schema over time. In fact, proponents of static typing would argue that the types make y

It reminds me more of the early days of touchscreen phone apps. There were a lot of super gimmicky apps (remember the virtual beer app?), games whose sole reason for existence was that they could use the accelerometer (as a crappy steering

I'm not aware of a similar feature built into other languages, but most of it could be easily achieved with almost any type system. Just have two separate types, e.g. UnsafeString and regular String, and some kind of `convert` function

There is also a possibility that your predictions about the future turn out to be wrong. It's definitely a balancing act. One extreme is always going for the instant gratification, paying no attention to how things fit into the overall

If this keeps being an issue, maybe browser vendors will eventually limit website CPU usage by default. For web apps that need it, it could be an explicit permission, like webcam or location access.

Mostly just lack of time, more important things got in the way, and it became less fun after the initial excitement. I'm also still not convinced that Kotlin/Native will catch on in any significant way, but we'll see.
