How the NZXT Hue+ works

Also applies to the NZXT Smart Device

TL; DR

Hue+ accessories use WS2812B integrated LED and controllers. Pinout is:

How to Change Open Files Limit on OS X and macOS

This text is the section about OS X Yosemite (which also works for macOS Sierra) from https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/#mac-os-x

The last time i visited this link it was dead (403), so I cloned it here from the latest snapshot in Archive.org's Wayback Machine https://web.archive.org/web/20170523131633/https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/

Mac OS X

To check the current limits on your Mac OS X system, run:

ahelord

'use strict';

// How to use?
// 1. Create `sequelize-schema-file-generator.js` in your app root
// 2. Make sure you've ran the `sequelize init` before (It should create `config`,`seeders`,`migrations` folders).
// 3. Update `DATABASE_DSN` below to match your connection string (works with any database adapter that Sequelize supports)
// 4. Run it with `node sequelize-schema-file-generator.js`
// 5. Review the generated migrations inside of the `migrations` folder.

• With Docker 1.8.0 shipped new log-driver for GELF via UDP, this means that the logs from Docker Container(s) can be shipped directly to the ELK stack for further analysis.
• This tutorial will illustrate how to use the GELF log-driver with Docker engine.
• Step 1: Setup ELK Stack:
  • docker run -d --name es elasticsearch
  • docker run -d --name logstash --link es:elasticsearch logstash -v /tmp/logstash.conf:/config-dir/logstash.conf logstash logstash -f /config-dir/logstash.conf
  • Note the config for Logstash can be found at this link
  • docker run --link es:elasticsearch -d kibana
• Once the ELK stack is up now let's fire up our nginx container which ships its logs to ELK stack.

• LOGSTASH_ADDRESS=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' logstash)
• `docker run -d --net=host --log-driver=gelf --log-opt gelf-address=u
