Use cases

1. Turning an eager, pure computation into a lazy one: RACSequence, RACSignal
2. Side-effecting work that is safe to perform multiple times: RACSignal, RACCommand
3. Side-effecting work that is safe to perform multiple times serially, but not concurrently: RACCommand, RefCount()
   • RACScheduler would seem to apply here, but execution could become interleaved and thus not serial
4. Side-effecting work that should only be performed once, then memoized: RACMulticastConnection with a RACReplaySubject, RACSequence
5. Enabling/disabling a UI based on whether work can be performed: RACCommand, RACReplaySubject
   • Replaying is a Good Idea™ because this information may arrive before the UI is ready for it
6. Updating a UI with information about work in progress: RACCommand, RACSubject

It's Impossible

I have reluctantly come to accept that it is impossible to create a "perfect" programming language. Every language is domain-specific in some sense, and many of the criteria that make a language good for one purpose are fundamentally in opposition to qualities that are good for another.

A classic example would be "scripting" languages versus "embedded" languages.

Good qualities in a scripting language are:

• Dynamic typing (no need to specify types, or cast between them)

    "Id": "Policy1234",
    "Statement": [
        {
            "Sid": "Stmt1234",
            "Action": [
                "s3:GetObject"
            ],
            "Effect": "Allow",
            "Resource": "arn:aws:s3:::foo/*",

MVVM example

For a command that initiates a network request when:

• The network connection is up (precondition)
• The network request is not already in progress (enforced serialization)

The lifecycle proceeds as follows:

1. The view model exposes the command and describes its behavior

Xcode Wish List:

Legacy Support

• Additional optional downloads:
  • Older SDKs, eg, for building ancient projects.
  • Older compilers (for same).
• Either ship gcc/llvm-gcc or don't. Don't ship clang and call it 'gcc', that just breaks anyone who actually needs GCC and finds your not-gcc in the PATH.

First grep the heroku logs for the message that will state that the debugger service has started:

$ heroku logs -t --app=[APP_ID] | grep 'Debugger listening on'

Then in another shell enable the debugger service of the Node process by connecting through SSH and sending the process SIGUSR1:

$ heroku ps:exec --app=[APP_ID]
