Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

Types are declared with : and not ::, and the consing operator conversely is :: instead of :
No where clauses, only let/in
The standard style is different, check http://elm-lang.org/docs/style-guide for reference
Multiline strings are a thing with """
Haskell's data corresponds to type in Elm, and also, Haskell's type corresponds to Elm's type alias
($) is (<|), but you don't use it all that much – Elm people like the flipped operator (|>) which lets you build something that reads like a pipeline
Related: Backticks will likely die soon in favour of functions that have an argument order that lends itself to pipelining with (|>)
Also, (.) is (<<), and a flipped version (>>) exists, but I don't see it used that much either
(>>=) is not an available operator and would not be polymorphic (no typeclasses, see below), and is instead commonly named SomeType.andThen – e.g. Maybe.andThen : Maybe a -> (a -> Maybe b) -> Maybe b

A compile-time 4-Bit Virtual Machine implemented in TypeScript's type system. Capable of running a sample 'FizzBuzz' program.

Syntax emits zero JavaScript.

How to notarize a Unity build for macOs 10.15 Catalina

As of January 2020, all apps running on macOs 10.15 Catalina are required to be notarized. For Unity games distributed outside the Mac App Store, such as with Steam, the notarization process is done post build using a series of Xcode command line tools.

Prerequisites

a Mac that is compatible with macOs 10.15 Catalina :
- MacBook (2015 or newer)
- MacBook Air (2012 or newer)
MacBook Pro (2012 or newer)
