Keynote I guess pushed an update that doesn't take hightlighted code from xCode anymore. So, I googled around and found hightlight. It is a super useful utitlity to do syntax highlighting from the command line.
$ brew install hightlight
If you are on Mavericks you may need to brew link lua to get it working right.
Hightlight has support for all kinds of languages and themes and it can wrap the code with line numbers, which is great.
How to flash your ESP8266 without a USB-Serial adapter but with an Arduino.
First be sure everything is connected correcly:

| TX | RX |
| RX | TX |
| GND | GND |
| GND | GPIO-15 |

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.
brew install dnsmasq
