• What do Etcd, Consul, and Zookeeper do?
  • Service Registration:
    • Host, port number, and sometimes authentication credentials, protocols, versions numbers, and/or environment details.
  • Service Discovery:
    • Ability for client application to query the central registry to learn of service location.
  • Consistent and durable general-purpose K/V store across distributed system.
    • Some solutions support this better than others.
    • Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.
• Centralized locking can be based on this K/V store.

Step 0:

Get Homebrew installed on your mac if you don't already have it

Step 1:

Install highlight. "brew install highlight". (This brings down Lua and Boost as well)

Introduction

Sometimes you may want to use a DNS server for specific domain requests and another DNS server for all other requests. This is helpful, for instance, when connected to a VPN. For hosts behind that VPN you want to use the VPN's DNS server but all other hosts you want to use Google's public DNS. This is called "DNS splitting."

Here, we run dnsmasq as a background service on macOS. The dnsmasq configuration described below implements DNS splitting.

Install

brew install dnsmasq

This is a sequel to "Postfix: relay to authenticated SMTP".

I would like to send mail from two different Gmail accounts using Postfix. Here is the relevant section in the Postfix documentation: Configuring Sender-Dependent SASL authentication.

As a concrete example, here's how to set up two Gmail accounts (only relevant sections of the config files are listed below):

/etc/postfix/main.cf:
    # sender-dependent sasl authentication
    smtp_sender_dependent_authentication = yes

sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relay

Experiments with libarchive read blocking: Part 1

Disclaimer: Don't know much about libarchive... yet!

Step 1: Describe the issue

• When reading a streamed archive using archive_read_open() [1] and archive_read_extract() [2] then a callback is called one or more times to read chunks of the archive.
• This creates an issue if (a) your program needs to wait for the next chunk to arrive, and/or (b) you want to process multiple archive streams in the same thread.
• Effectively archive_read_open() [1] and archive_read_extract() [2] block until all the necessary number of archive stream chunks have been read via the callback.

Configure Postfix for Gmail SMTP in Mac OSX

This should work on at least:

• 10.9 Mavericks
• 10.10 Yosemite

Taken from Using MacOSX Lion command line mail with Gmail as SMTP

Edit file /etc/postfix/main.cf and add this to the bottom:
