Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

Table of Content

Step 1 - Create a New SSH Key

We need to generate a unique SSH key for our second GitHub account.

ssh-keygen -t rsa -C "your-email-address"

Be careful that you don't over-write your existing key for your personal account. Instead, when prompted, save the file as id_rsa_COMPANY. In my case, I've saved the file to ~/.ssh/id_rsa_work.

Step 2 - Attach the New Key

Installation of NixOS with encrypted root

These are my notes on instaling NixOS 16.03 on a Lenovo ThinkPad X1 Carbon (4th generation) with an encrypted root file system using UEFI.

Most of this is scrambled from the following pages:

How to install Ubuntu 14.04.1 LTS 64-bit on a MacBook Pro Retina 15" Mid 2014 (11,3)

download

Ubuntu 14.04 Desktop 64-bit ISO (default, non-Mac version)

UNetbootin
http://unetbootin.sourceforge.net/
Broadcom 802.11 Linux STA wireless driver source dependencies
http://packages.ubuntu.com/trusty/all/dkms/download

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
