Enabling Apple CarPlay on a 2016 Honda CR-V EX via Firmware Update

Enabling Apple CarPlay in a 2016 Honda CR-V EX is possible by updating the firmware on the stock infotainment system – no hardware changes are required. In fact, Honda released a software update (initially as a beta) for 2015–2016 CR-V EX/EX-L models that adds Apple CarPlay and Android Auto functionality to the existing stereo. By following the steps below, you can perform this update yourself using a USB flash drive. This guide provides a step-by-step walkthrough, as well as tips to address potential issues (such as GPS antenna interference) and important precautions. The process is straightforward and suitable for someone with basic technical skills, as long as instructions are followed carefully.

Multi-host Galaxy Server

usegalaxy.org uses a five host setup:

• 2 x hosts for serving web requests
• 2 x hosts for handling jobs and Pulsar staging
• 1 x host for the database

Web requests are balanced only with a DNS round-robin (i.e. there are two A records for usegalaxy.org), which is not ideal since it does not do any load balancing or health checks. A better setup would include a 6th host with nginx proxying the web hosts.

Background

Two commonly used [Galaxy][galaxy] server configurations are the use of [uWSGI Zerg Mode][uwsgi-zerg-mode] and [uWSGI Mules][uwsgi-mules] as [Galaxy job handlers][galaxy-scaling]. These features are not easily compatible because Galaxy job handlers rely heavily on having unique server names, and handlers' server names must be persistent across restarts. Because zerg mode results in running two Galaxy servers simultaneously (however briefly), using mules with zerg mode would necessarily mean running mules with overlapping server names.

Solution

In a typical Galaxy zerg mode setup, the newly started zergling (B) terminates the old zergling (A) once B is ready to serve requests. Zergling B then continues to serve requests until another zergling (C) is started and terminates B.

It is possible to get both zerg mode and mules working together by configuring zergling B to start without mules, and perform a double zerg dance on each restart:

Adding a new disk to a bhyve vm takes a few steps.

  1.  increase the quota on the zfs dataset to accomodate the additional
      space.
  2.  create a zvol inside the zone
  3.  stop the vm and update its configuration to reflect the change
  4.  start the vm, login and use the disk
