Extensions

Following are the extensions required for neovim:

Controlling the Brother P-Touch Cube label maker from a computer

The Brother PTP300BT label maker is intended to be controlled using the official Brother P-Touch Design & Print iOS/Android app. The app has arbitrary limits on what you can print (1 text object and up to 3 preset icons), so I thought it would be a fun challenge to reverse engineer the protocol to print whatever I wanted.

Python code at the bottom if you want to skip the fine details.

Process

Intitially I had a quick peek at the Android APK to see if there was any useful information inside. The code that handles the communication with the printer in Print&Design turned out to be a native library, but the app clearly prepares a bitmap image and passes it to this native library for printing. Bitmaps are definitely something we can work with.

2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

Step 1: Server Credentials

This assumes you are now connected to the server via SSH.

sudo -s Enter root mode for admin access
groupadd devgroup Create new group to be later granted access to /var/www/html

Creating a new Root User

useradd -G root,devgroup masterdev Create new root user. Also add to the devgroup
passwd masterdev Change password for the new root user
At this point, you'll need to input your new root user's new password

A Starting Point for using Emacs & Evil-mode

(I wrote a bit about why Emacs and Vim on my blog and thought it might be nice to give some starting point for people that want to try it.)

If you just want to play around with Emacs & Evil mode do the following:

mkdir ~/.emacs.d/
copy init.el into ~/.emacs.d/
Download Emacs from http://emacsformacosx.com
