Installing PDFtk Server edittion on your Mac

This workaround install is necessary because PDFtk was pulled from homebrew-cask due to issues with it aggressively overwriting file permissions that could impact other installed libraries. See this homebrew-cask issue.

The following steps worked on Mac OS X 10.10.1 with a standard brew installation for the PDFtk Mac OS X server libary version 2.02.

All Terminal commands separated by a full line space. Some commands wrap into multiple lines.

Download and extract the Mac OS X server install pacakge

This is a rough guide to setting up browser testing through Selenium on Windows Subsystem for Linux (WSL), aka Bash on Ubuntu on Windows. It assumes the following environment:

• Windows 10, running WSL
• A Ruby dev environment, running inside WSL
• Code that we want to test using a web driver, in this case Selenium, with a Capybara and RSpec test framework

The coding project folders are stored in the main Windows filing hierarchy and accessed via dev/mnt, but that makes no real difference to development and testing other than making it possible to edit the code using a GUI based editor within Windows.

The problem with browser testing in WSL is that it relies on opening and controlling a web browser, and browsers don’t work on WSL at present as it deliberately doesn’t include X Windows or some other GUI manager - it’s meant to be command line after all. So while you can apt-get firefox, trying to actually run it isn’t going to work.

How to automatically start ssh server on boot on Windows Subsystem for Linux

---

This works with Ubuntu 18.04LTS. I make no promises about other distributions, but direct anyone else to an older Gist which apparently works for 16.04LTS.

Microsoft partnered with Canonical to create Bash on Ubuntu on Windows, running through a technology called the Windows Subsystem for Linux. Below are instructions on how to set up the ssh server to run automatically at boot.

1. Uninstall and reinstall the ssh server using the following commands:
   1. sudo apt remove openssh-server
   2. sudo apt install openssh-server
2. With this setup, the ssh server must be turned on every time you run Bash on Ubuntu on Windows, as by default it is off. Use this command to turn it on:

i = (1+rate/12)**(12/12)-1
annuity = (1-(1/(1+i))**time)/i
