Two Lua scripts for Redis to turn HGETALL and HMGET into dictionary tables
-- gets all fields from a hash as a dictionary
local hgetall = function (key)
local bulk = redis.call('HGETALL', key)
local result = {}
local nextkey
for i, v in ipairs(bulk) do
if i % 2 == 1 then
nextkey = v
else
result[nextkey] = v

Latency numbers every programmer should know

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

A Python script to break audio into chunks of smaller audios and using Google API to get Speech to Text.
'''
A hack based on this http://mikepultz.com/2011/03/accessing-google-speech-api-chrome-11/. While with smaller voice samples google speech to text works really good, as length increases quality decreases. So here using audiolab and numPy we are breaking audio sample, in smaller chunks, and removing blank/empty spaces from audio signal and then pushing them to google for processing.
It takes wav file format as input but can be changed to other formats too.
