Concrete proposal for async semantics in Swift

Async/Await for Swift

Introduction

Modern Cocoa development involves a lot of asynchronous programming using closures and completion handlers, but these APIs are hard to use. This gets particularly problematic when many asynchronous operations are used, error handling is required, or control flow between asynchronous calls gets complicated. This proposal describes a language extension to make this a lot more natural and less error prone.

This paper introduces a first class Coroutine model to Swift. Functions can opt into to being async, allowing the programmer to compose complex logic involving asynchronous operations, leaving the compiler in charge of producing the necessary closures and state machines to implement that logic.

For white hat hackers setting passwords to open Redis instances

Dear white hat attackers,

recently we observed a number of Redis instances that were targeted by a simple attack, consisting in setting a password using the CONFIG SET requirepass <password> command to instances which are left open on the internet.

This is, in my opinion, a good idea, since those Redis instances are going to be cracked anyway. I believe you are doing this in order to make Redis users aware they forgot to setup firewalling rules in order to make their instances not reachable from the outside.

Internet Scale Services Checklist

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

Basic tenets

  • Does the design expect failures to happen regularly and handle them gracefully?
  • Have we kept things as simple as possible?

How To Install Memcache on MAMP 2

How To Install Memcache on MAMP 2

Note: This is an old guide and may not work for newer versions of macOS. Please see comments below for additional steps.

  1. Install memcached. I'd suggest using homebrew. brew install memcached
  2. Select your desired version of PHP that you'd like to use in MAMP. This dropdown is located in the PHP tab in MAMP PRO.
  3. Visit the Downloads Page on php.net and download the source code. If your release isn't listed, visit the Releases page.
  4. Extract the source into /Applications/MAMP/bin/php/[php version folder]/include/php.
  5. /Applications/MAMP/bin/php/[php version folder]/include/php/configure
  6. /Applications/MAMP/bin/php/[php version folder]/bin/pecl i memcache.
