Multi-Output Audio Devices in El Cap

I am usually the first one in our office, by choice I promise. I like to start the morning off without headphones- as I know I will probably be wearing them all day. I don’t have any type of speakers, but what I do have is two Acer G257HU via HDMI and MiniDP to HDMI attached to my MBPr.

Today I learned you can aggregate output audio devices.

From Audio MIDI Setup, in your Utilities Folder

You can configure a Multi-Output Device, by hitting the “+” button per OS X usual.

Select the attached devices you want to be rolled into the device. You can also specify location of the devices, left/right or if they are independently stereo.

In this instance I selected the two HDMI monitors that have (albeit crappy) internal speakers. And now have music out of both monitors rather than the left OR the right.

I am also using Background Music which is a rad project over on GitHub by Kyle Neideck reminiscent of Rouge Amoeba’s old independent application audio mixer application, the name of which escapes me. You can see it as another output device as an option.

Quick switch between devices by Alt+Click ‘n on the Volume control in the menu bar.

Just a quick tip from something I wish I knew ages ago. Hope this helps someone.


Munkireport-PHP on Docker

In my previous post I delved into getting a munki repo with ssl client-server cert protecting up and running on a docker host. You can read that here.

So the next step I wanted to get up and running next to it was the great tool Munkireport-PHP.  More than likely if you are looking into docker as an option for a munki repo server you have some experience with munkireport-php as a reporting tool for your fleet. I am not endorsing this as the only way or even a preferred way- I just wanted to see what it looked like to get it up and running on a docker host- and it was super easy (in comparison to getting a munki repo configured and up and running).

Munki-Docker & SSL (proofing a concept)


The ustwo docker munki git repo has been removed, thanks to Clayton Burlison you can see a forked version here


This is a stumbling journey of a layman and how he got a proof of concept munki repo secured with ssl in some way on a docker host. Before this I knew little about docker, less about ssl/certs and had barely touched Ubuntu let alone a server version.


The end game: Have a Munki Repo that requires client side ssl certs for authentication (as a means to protect for un authorized access to a repo) and hosted in a docker environment (for easy maintenance and recreation of servers in multiple locations.

Penn State Mac Admins Conference

I will be presenting the MacAdmins Conference at Penn State this summer with my good friend and colleague Sean Kaiser find more about him here. I will be heading up Life In A Post Xserve World and Sean 2 years after 1400+ computers in 3 weeks. Are we still nuts?. Here is a full list of topics and speakers. Looking forward to being inducted into a great community, and hope I can give just the slightest amount of wisdom back. 

IF / Do

IFTTT has been a handy web app for simple tasks that I’ve used for a while now. With IFTTT’s iOS app update to IF and the release of Do Button the integration has gotten a bit more interesting. Our IT team has been giving Slack a go these past couple weeks, which we love, and I’ve made a couple fun IF / DO integrations. First a handy DO Button that sends a message to slack saying there is coffee dripping in the main IT office, a handy heads up as I am usually one of the first to arrive. Also realistic application of a time tracker, that also notes location and saves it to a Google Spreadsheet. And another Do Button that tells the team on slack I am out for the day.

Also using the IF app on iOS we’ve began experimenting with location reporting, which tech is at which building, and an ever up-to-date status. I liken it, for all you Harry Potter fans, to the Weasley’s clock that sits in Burrow allowing for them to see what each other is up too with some generality. It’s quite simple, as  IFTTT works on an If-This-Then-That. Using iOS location I set a fence around each building, and IF I cross that fence THEN post to slack THAT my location is ‘name of building’ easy as that.

Here are some of the integrations:

Now you may have noticed that the current actions are not enabled, well here is where I still need to tinker. Several of the building sit on roads that are frequently driven to access other buildings, thereby triggering the location update, even with the geofence set up fairly tight on a building. Also this requires for your location data to be active quite often, which leads to poor battery life and high overall data usage. Another issue I’ve notice, is besides switching all the recipes off and then back on everyday, theres not ay to regulate on a time table when they are active, a functionality I hope IFTTT releases in the future.

In summary the location reporting to a slack channel works, just at a cost of battery and data:


Making some space for fun-

The last year of attaining my masters was hard, last year in general was hard. I feel like I “did” a ton. Had a wedding, moved into a new house, finished my masters, and it was busy and chaotic. And there were parts of it that were fun, but I don’t think I made anytime for having some fun. So since graduation I have rekindled my love for video games, now hold on if I lost you. I recently started down the path of Kerbal Space Program, which is more spaceflight sim than game… mostly.
