Creating a redis Module in 15 lines of code!

A quick guide to write a very very simple "ECHO" style module to redis and load it. It's not really useful of course, but the idea is to illustrate how little boilerplate it takes.

Step 1: open your favorite editor and write/paste the following code in a file called module.c

#include "redismodule.h"
/* ECHO <string> - Echo back a string sent from the client */
int EchoCommand(RedisModuleCtx *ctx, RedisModuleString **argv, int argc) {

APIs: the good, the bad, and the ugly

Talk will focus on web APIs, but applies to many programmatic APIs, too

good: it exists (and bonus points if it's interactive: I/O Docs is one nice example)

Mnemonic Encoding Word List

http://web.archive.org/web/20090918202746/http://tothink.com/mnemonic/wordlist.html

The wordlist contains 1626 words.
All words are between 4 and 7 letters long.
No word in the list is a prefix of another word (e.g. visit, visitor).
Five letter prefixes of words are sufficient to be unique.
The words should be usable by people all over the world. The list is far from perfect in that respect. It is heavily biased towards western culture and English in particular. The international vocabulary is simply not big enough. One can argue that even words like "hotel" or "radio" are not truly international. You will find many English words in the list but I have tried to limit them to words that are part of a beginner's vocabulary or words that have close relatives in other european languages. In some cases a word has a different meaning in another language or is pronounced very differently but for the purpose of the encoding it is still ok - I assume that when the encoding is

Getting Pow to work in OS X Yosemite

Some parts taken from: https://gist.github.com/kujohn/7209628

ipfw is officially deprecated and removed in OS X Yosemite. Pow requires another program pf to handle the port forwarding.
