Concurrency with ViewModel & Repository

From the article: https://medium.com/androiddevelopers/coroutines-on-android-part-iii-real-work-2ba8a2ec2f45

• As a general pattern, start coroutines in the ViewModel.
• A repository should prefer to expose regular suspend functions that are main-safe.

Angle Brace Delimiters for Go Contracts

This document references the Contracts Draft Design for Go Generics, dated 31 July 2019.

The current design uses parentheses to delimit type parameter clauses, but this makes the code difficult to read. This is covered briefly in Non-Parenthetical Delimiters from the essay Towards Clarity: Syntax Changes for Contracts in Go, as well as in many other points of feedback which can be found at https://github.com/golang/go/wiki/Go2GenericsFeedback as linked documents or inline comments.

The official draft states:

Why not use the syntax F<T> like C++ and Java?
When parsing code within a function, such as v := F<T>, at the point of seeing the < it's ambiguous whether we are seeing a type instantiation or an expression using the < operator. Resolving that requires effectively unbounded lo

Towards Clarity: Syntax Changes for Contracts in Go

There are two main parts to the Contracts Draft Design:

• Type Parameters
• Contracts

Type Parameters are mostly independent of Contracts; Contracts builds on Type Parameters. The two concepts are well thought-out and many corner cases have been looked at.

These are some specific points that I think are done well by the current generics draft proposal, not in any particular order:

• Type parameters (generics!) in functions, structs, etc.

//A generics proposal for Go, introducing one new type (generic) and one new builtin function (typeof), no syntax changes.

//Function add takes arguments of any type.
//The return value is automatically inferred based on the arguments, can be inlined by the compiler.
//Both arguments must be the same type and addable or else a compiler error will be raised.
//It's the developer's responsibility to document which types can be passed to this function.
func add(a, b generic) generic {
    return a+b
}

1. Really good software can be written only by very small groups of very skilled programmers.
2. Really good software is almost always a labor of love.
3. Really good software is almost always begun because the author himself needs it; it makes his computer do something that he really wants it to do.
4. Really good software is never finished; it continues to grow. If it doesn’t grow, it decays.
5. To evolve into really good software, a program or system must be “hacked at”.
6. To evolve into really good software and remain good, a program or system must develop an intelligent, adventurous, passionate user community with enough influence to be able to guide its further development.
