You're confusing UnityJS with UnityScript, which is a common misconception. I wrote about the anathema that is UnityScript in another posting to this thread, and it is a completely different thing that the standard JavaScript engine that UnityJS uses.

UnityJS seamlessly supports TypeScript and all the standard JavaScript based libraries, languages, development tools, and linters, just like any browser or node.js server does, while UnityScript is nowhere near compatible enough with standard JavaScript to compile the output of the TypeScript compiler, it's not well supported by many IDEs, it's way behind the latest version of JavaScript, has non-standard half-baked extensions, and it is not capable of running any of the millions of standard JavaScript library, like UnityJS can.

So how do you like the C# and UnityScript debugging tools on the iOS, Android, and WebGL Unity3D platforms?

How does MonoDevelop compare to the standard JavaScript debuggers built into all web browsers, and their interactive consoles and data structure browsers, which support remote debugging of code running on mobile devices?

Can you set a source level breakpoint on your C# or UnityScript code that's running on an iOS device in a WebGL/WebAssembly based browser?

And how long does your typical Unity3D application take to compile and deploy, before you can see the changes you made to your code?

(I know the answers, I'm just asking rhetorically, because you know the answers too: Debugging Unity C# or UnityScript code totally sucks, especially on mobile devices and web browsers, and recompiling it is glacially slow. The MonoDevelop debugger is terrible, and it doesn't even support the il2cpp back-end, which includes iOS and WebGL, and it barely supports the deprecated Mono back-end, and crashes all the time if you can even get it to connect for a few seconds. Those are extremely painful problems that UnityJS solves.)

Not JS, but I've worked for a couple of competitors and can confirm. There were a few truly brilliant individuals, but most of the staff was unexceptional, and the general level of the tech varied between standard corporate and outright appalling. It turns out that if you have enough money, you can simply keep throwing programmers into the firefight until something sort of works. They're truly too rich to fail.

But, not an enjoyable ride if you actually love quality tech.

I thought I would also add my two cents, though there have been many excellent responses already. I recently defended my PhD in Physics (MIT '18).

First of all - great idea! It is never too late to learn math and physics! In fact, with hard work and commitment, anybody can muster them to a high level.

(1) Reading =/= understanding in math and physics. You understand a topic only if you can solve the problems.

(2) Work through the solved problems you encounter in textbooks carefully.

(3) Most people around me have never read any physics textbook cover to cover. E.g. reading Halliday, Resnick & Walker completely might take you years! Not all topics are equally important. Focus on the important parts.

(4) You need guidance on what is important and what is not. Online courses, college material (especially problem sets!), teaching webpages could be a helpful guide. MIT OCW is an excellent resource, once you are ready for it.

(5) Finding someone to talk to is really useful. You will likely have questions. Cultivating some relationship that allows you to ask questions is invaluable.

(4) College courses in math and physics have a very definitive order. It is really difficult to skip any step along the way. E.g. to understand special relativity, you must first understand classical physics and electrodynamics.

(5) Be prepared that the timescales in physics are long. Often, what turns people off is that they do not get things quickly (e.g. in 15-30 minutes). If you find yourself thinking hours about seemingly simple problems, do not despair! That is normal in physics.

(6) You have to 'soak in' physics. It takes time. Initially, you might feel like you do not make a lot of progress, but the more you know, the quicker it will get. Give yourself time and be patient and persistent.

(7) Often, just writing things down helps a lot with making things stick. It is a way of developing 'muscle memory'. So try and take notes while reading. Copying out solved problems from textbooks is also a good technique.

(8) Counterintuitive: If you get completely stuck, move on! Learning often happens in non-linear ways. If you hit an insurmountable roadblock, just keep going. When you return in a few days/weeks, things will almost certainly be clearer.
Why 'level'? Its a different body of knowledge.

I really doubt it. Maybe one day but certainly not "quickly" and especially not just from Vulkan.

I want to like Godot but it feels like it's making the same mistakes Unity 5.x and earlier did with fixed shader and script languages that just aren't as useful as the languages they're abstracting. I want to use GLSL or Vulkan or DX12 not a custom language that will get in my way. Its a C++ engine that uses script runtimes like Unity did. This makes it hard to optimize across languages and why Unity went down the whole IL2CPP path. Now Unity is moving more and more features into C# with a custom C# compiler to better optimize with user code. Godot will have to succeed where Unity could not.

Godot looks very promising but if you don't think its an uphill battle or that Unity is easy to beat you're mistaken.
It's just a continuation of the trickle-down approach that's been concentrating wealth in the US for the past four decades.

The US was founded in large part as a revolt against British crown corporations. And until the mid 1800s, only public-interest corporations were allowed. But once the railroads had bought enough of the government, corporations got human rights, and the US was managed for their benefit.

Probably not, but the reason to get antibody tests is to know you're past it and hopefully wont be a carrier to potentially infect others (e.g., if you live with your elderly parents)

That said, there are no hard rules

- you can still spread it physically (e.g., via clothing, on hands, surfaces)

- it isnt 100% clear you cannot be re-infected

- it isnt clear the length of time immunity is conferred

- it isnt clear if the virus might mutate drastically overstepping immunity from a previous infection

>But debugging C#, especially on mobile and WebGL platforms, is a horrible primitive retrograde nightmare. And it takes a long long time to recompile, with some projects taking a good slice of an hour to build.

A 2gig mobile game should take 20 minutes to build to device tops and that's all from asset compression anyway. Recompiling the code should take no more than a minute unless you're using a potato.

I don't even understand this rhetoric. You can't 'bailout' workers. You can send workers cash, which the government does, but you also should help businesses, because that's where people go to work in the first place.

I'm not really sure what the purpose of this antagonism is, as if protecting employment isn't in the interest of workers, or as if helping businesses and workers is mutually exclusive.

One of my favorite JIT techniques from the era is PIC, polymorphic inline caching. A method send (virtual function call) would be statically coded to call the hottest implementation of a virtual function. The virtual function itself would check that the incoming object had the right type. If not, the fully polymorphic dispatch mechanism would kick in. Statistics would be tracked and could lead to a decision to overwrite the static call with a call to the new hot implementation. I think this was demonstrated on Strongtalk.

Do you mean it "should" or "does" take no more than a minute? And do you honestly find debugging Unity3D iOS apps running on mobile devices and WebAssembly/WebGL apps running in the browser a pleasant experience? Do you think MonoDevelop (when it works and doesn't crash) is better than the Chrome or Safari debugger?

I don't know what kind of toy games you're compiling that take no more than a minute to completely compile and deploy with Unity3D: "2gig" of what, code or just video?

I'm not talking about pressing "Play" in the editor or deploying on Windows or Mac with Mono, I'm talking running it in the browser with the WebGL back-end, or on an iPad with the iOS back-end, using il2cpp and Emscripten or XCode, which are enormously slow and complex.

It certainly does take a long time on my Mid 2014 MacBook Pro (which while not new, is certainly not a potato), and it makes it useless for doing anything else while it's compiling, and spins the fan up to its highest speed and pins the CPU all that time.

A large complex multi player networked AR/VR iOS app like Pantomime with a lot of content including code and libraries and resources and plugins and shaders regularly took me a good part of an hour to compile, build and deploy. Developing UnityJS was my response to that problem, so I could rapidly iterate by changing code and JSON data and other resources, without recompiling.

https://vimeo.com/154755183

https://vimeo.com/240612327

WebGL and iOS builds are especially slow, because they go through layer after layer of cross-compilers, from C# to CIL with the Mono compiler, and then from CIL to C++ with il2cpp, then the XCode/CLang/Assembler/Linker or Emscripten/WebAssembly chains do their own ridiculously complex things, and there's also a significant amount of time spent packaging and compressing resources and data in various formats and wrappers.

You have to wait not just for the C# code to compile, and for the shaders and the resources to be processed, but for the entire multi-level Rube-Goldbergesque translation and packaging process to finish, then that build must be deployed on your web server or mobile device.

I'm talking about the actual turn-around time between when you make a change to the code, and see the results. You know, the thing you have to do again, and again, and again, and again, and again. So it adds up quickly.

UnityJS drastically slashes that time, however long it takes (and I have a hard time believing it takes no more than a minute for you, unless your app is trivially simple), to just a few seconds of refreshing the web page or quitting and restarting the iOS app.

For fast debugging turn-around, you can tell it to load the JavaScript code, JSON configurations, and other resources from a web server, and edit the code and content live on the server, so the app downloads the fresh JavaScript code, in mere seconds, each time you run it, without any recompiling.
This raises an interesting question, what added value do "classes" provide over prototypes?

The way I see it is if every object (-instance) can be derived from another instance that makes programs harder to understand. Classes are invariants of behavior which all their instances obey, which makes it possible to reuse your understanding of a class to understand all its instances.

It's a bit like the certificate systems we have in the human society. When someone is a certified medical doctor we know more or less what they can do, we don't have to investigate in detail do they have the skill to be a physician.

But I'm not sure this is all there is to the benefit of classes. Is it?
I'm also curious about this. As a data point: we're fully remote and are in a similar product space @ Guilded (http://www.guilded.gg). One of our best early decisions was to use our product exclusively for all of our work communication.

For us, this degree of dogfooding - which is really only possible at a fully-remote company - has been directly responsible for too many features and improvements to count. There's no better way to develop empathy for your users and a deep care for your products than to have your entire team rely on them for their most critical communications every single day.

Not all companies build products that facilitate remote collaboration, but I think that remote work presents some unique opportunities for those that do.

I don't think the quote you provided says anything about false positives; at least, I really hope it doesn't. A 10% false positive rate would be ridiculous. If 0.1% of the population has SARS-CoV-2, a test has a 10% false positive rate, and you get a positive result on that test, you only have about a 1% chance of actually being infected.

That's a little unintuitive, but here's how it breaks down, without taking into account false negatives:

* 10% of the population will receive a false positive

* 0.1% of the population will receive a true positive

Which category are you more likely to fall into--10% of the population or 0.1%? You're 100 times more likely to fall into the false positive category.
