user: From the passage below, please extract the names of the general partners from a16z.

assistant: In addition to the founders, Marc Andreessen and Ben Horowitz, a16z general partners include John O'Farrell, Scott Weiss, Jeff Jordan, Peter Levine, Chris Dixon, Vijay Pande, Martin Casado and Sriram Krishnan.

user: A lead or A manager?

assistant: Both are importent,

1. A manager is important to keep your work organized and get the timeline done
2. A leader is needed to guide you technically

user: What is the difference between the Scala Future onComplete and andThen functions?

assistant: Both `andThen` and `onComplete` allow you to observe the result of some future via a callback function. However, `andThen` can be chained, and unlike `onComplete`, it guarantees the order in which callback functions will be applied. In addition, the callback given to `andThen` may be a partial function, handling only a subset of outcomes (e.g., only `Success` or only `Failure`).

Consider the following example using `andThen` and `map`:

```
def demoAndThen(fut: Future[Int]): Future[Int] = {
  fut.andThen { case Success(value) => println(s"andThen1: $value") }
    .andThen { case Success(value) => println(s"andThen2: $value") }
    .map { i =>
      println(s"map: $i")
      i
    }
}
```

When `fut` completes successfully, "andthen1: ...", "andThen2: ..." and "map: ..." will be printed in that order.

Consider the analogous example using `onComplete` and `map`:

```
def demoOnComplete(fut: Future[Int]): Future[Int] = {
  fut.onComplete { t: Try[Int] => println(s"onComplete1: $t") }
  fut.onComplete { t: Try[Int] => println(s"onComplete2: $t") }
  fut.map { i =>
    println(s"map: $i")
    i
  }
}
```

In this case, when `fut` completes successfully, "onComplete1: ...", "onComplete2: ..." and "map: ..." will be printed in some unspecified order.

Although `andThen` is chained, the callback function does not generally affect the outcome of the resulting `Future`. But be aware: if the callback throws some fatal errors, the resulting future will never complete.
