Practice Exam Attempt (3) Carefully taken with notes

Got an 16/20 on the latest practice exam. Missed questions 5, 7, 12, 13.

Summary of why missed each question:

5

always favor simpler method (cbt (cloud big query tool) vs hbase cli) … I feel uneasy with this answer

7

prefer simpler method. pub/sub more than capable. kafka is overkill. this question showed my lack of knowledge of pub/sub capabilities

Originall From: Posted 2015-05-29 http://ubwg.net/b/full-list-of-ffmpeg-flags-and-options

This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full.

usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}…

Getting help:
    -h — print basic options
    -h long — print more options
    -h full — print all options (including all format and codec specific options, very long)

Icecast protocol specification

What is the Icecast protocol?

When speaking of the Icecast protocol here, actually it's just the HTTP protocol, and this document will explain further how source clients need to send data to Icecast.

HTTP PUT based protocol

Since Icecast version 2.4.0 there is support for the standard HTTP PUT method. The mountpoint to which to send the data is specified by the URL path.
