Thoughts on Swift 2 Errors

When Swift was first announced, I was gratified to see that one of the (few) philosophies that it shared with Objective-C was that exceptions should not be used for control flow, only for highlighting fatal programming errors at development time.

So it came as a surprise to me when Swift 2 brought (What appeared to be) traditional exception handling to the language.

Similarly surprised were the functional Swift programmers, who had put their faith in the Haskell-style approach to error handling, where every function returns an enum (or monad, if you like) containing either a valid result or an error. This seemed like a natural fit for Swift, so why did Apple instead opt for a solution originally designed for clumsy imperative languages?

I'm going to cover three things in this post:

warning: ignoring broken ref refs/remotes/origin/HEAD


➜   ✗ g symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/develop
➜   ✗ g fetch --prune
➜   ✗ g gc

This is a proposal for lightning talk at Reactive Conf. Please 🌟 this gist to push the proposal!

Memory Leak Testing in 2017

Hi, I am Andy, creator of leakage - the node-powered memory leak testing library.

Instead of manual debugging it provides a structured approach to fix or even prevent memory leaks.

	* Base contract that all upgradeable contracts should use.
	*
	* Contracts implementing this interface are all called using delegatecall from
	* a dispatcher. As a result, the _sizes and _dest variables are shared with the
	* dispatcher contract, which allows the called contract to update these at will.
	*
	* _sizes is a map of function signatures to return value sizes. Due to EVM
	* limitations, these need to be populated by the target contract, so the
	* dispatcher knows how many bytes of data to return from called functions.
