Primeiro, verifique se o módulo está presente na sua instalação digitando pacmd em seu terminal, listando todos os módulos presentes pelo comando list-modules e procurando por module-echo-cancel. Não está presente? Você precisa adicionar algumas linhas ao arquivo de texto responsável pela configuração do PulseAudio.

Com o seu editor favorito, abra (com privilégios de administrador) o arquivo /etc/pulse/default.pa e adicione as seguintes linhas ao fim do arquivo:

### Enable Echo/Noise-Cancellation
load-module module-echo-cancel use_master_format=1 aec_method=webrtc aec_args="analog_gain_control=0\ digital_gain_control=1" source_name=echoCancel_source sink_name=echoCancel_sink
set-default-source echoCancel_source
set-default-sink echoCancel_sink

Problem Domains For Which Many Create and Publish Their Own Solution

I find that certain problems attract the creation of many solutions. We are overwhelmed with slightly similar yet incompatible and potentially incomplete solutions.

Why is that so? Which domains show this pattern?

My hypothesis is that these problems seem easy to approach from one idiosyncratic perspective while at the same time being hard to complete. Therefore no-one’s satisfied or able to judge existing solutions and end up creating yet another one.

In certain domains, incumbent solutions also may appear bloated, and therefore it’s easy to think one can do better, because the 50% solution appears leaner. Problem is, the remaining 50% is where the necessary risk mitigation, adaptation is. An example of that is the appearance of poorly made (but lean) databases in the age of NoSQL, which claimed to be leaner just because they did not discover yet all the things their historical competitors had discovered they had to do.

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.

Principles of Adult Behavior

1. Be patient. No matter what.
2. Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.
3. Never assume the motives of others are, to them, less noble than yours are to you.
4. Expand your sense of the possible.
5. Don’t trouble yourself with matters you truly cannot change.
6. Expect no more of anyone than you can deliver yourself.
7. Tolerate ambiguity.
8. Laugh at yourself frequently.

## First step: Install the Oracle Client

1. Download Instant Client from http://www.oracle.com/technetwork/indexes/downloads/index.html#database (you must be registered in Oracle; it's free). You will need `instantclient-basic-*-*.zip` and `instantclient-sdk-*-*.zip`  files.
