The Y Combinator is a classic lambda calculus construct that many people find baffling. Here's my attempt to explain it as clearly as possible (no promises!). Familiarity with Haskell syntax is assumed.
The problem we're trying to solve is how to write an anonymous function (a "lambda") that is recursive. Normally, if you want to write a recursive function, it looks like this:
Comparison of ZeroMQ and Redis for a robot control platform
ZeroMQ vs Redis
This document is research for the selection of a communication platform for robot-net.
Goal
The purpose of this component is to enable rapid, reliable, and elegant communication
between the various nodes of the network, including controllers, sensors, and actuators
(robot drivers). It will act as the core of robot-net to create a standardized infrastructure
for robot control.
Ideas and guidelines for architecting larger applications in Elm to be modular and extensible
Architecture in Elm
This document is a collection of concepts and strategies to make large Elm projects modular and extensible.
We will start by thinking about the structure of signals in our program. Broadly speaking, your application state should live in one big foldp. You will probably merge a bunch of input signals into a single stream of updates. This sounds a bit crazy at first, but it is in the same ballpark as Om or Facebook's Flux. There are a couple major benefits to having a centralized home for your application state:
There is a single source of truth. Traditional approaches force you to write a decent amount of custom and error prone code to synchronize state between many different stateful components. (The state of this widget needs to be synced with the application state, which needs to be synced with some other widget, etc.) By placing all of your state in one location, you eliminate an entire class of bugs in which two components get into inconsistent states. We also think yo
Hi. My name is Sadayuki "Sada" Furuhashi. I am the author of the MessagePack serialization format as well as its implementation in C/C++/Ruby.
Recently, MessagePack made it to the front page of Hacker News with this blog entry by Olaf, the creator of the Facebook game ZeroPilot. In the comment thread, there were several criticisms for the blog post as well as MessagePack itself, and I thought this was a good opportunity for me to address the questions and share my thoughts.
My high-level response to the comments
To the best of my understanding, roughly speaking, the criticisms fell into the following two categories.
