Twin Cities Mac Admins » Meetup notes – April 23, 2015

Featured Presentation Jacob Salmela with Hopkins High School provided our feature presentation Under Cover Of Shell (Scripting). Take a look at Jabob’s website and his GitHub repository. You’ll find he’s solved plenty of issues with scripting. He introduced us to GeekTool, a desktop information display, which he populates with loads of geeklets. And he got a few chuckles explaining his Single-user Mode Intrusion-Detection System with Star Trek red alert klaxon (see slide 35).

Octal Dump (od) Shows You Hidden Characters And ASCII Values

Octal Dump (od ), lets you see ASCII character values as well had hidden ones (an ASCII dump).  It’s pretty rare that you would ever need to do this, but it is very useful when you do, even though it sounds like something that should be relegated to a private restroom.  Throw in a few tarballs and you’re all set for some adolescent humor.

Pi-hole Improvements: More Ad Domains And A Better Script

The Pi-hole blocks ads for every device on your network by re-routing known ad-serving domains to a fake Web server.  I made a new branch of the project, which I will eventually merge back in with the master project.  This branch has additional domain sources (306,000), and a better script that uses a loop so additional source URLs can be added in much easier.

In addition, I also added a list of sites that have domain blacklists, which I hope to add into the script.  Some of them need a lot of formatting, but there are many to look at.  Eventually, the Pi-hole can also be used to block malware domains, phishing domains, spam domains, and anything else you don’t want to see or visit while using the Internet.

OS X Yosemite (10.10.3) Has A New Hidden Spotlight Feature (Command+Control+D)

Prior to 10.10.3, you could use the keyboard shortcut Command+Control+D while hovering over a word to look up its meaning but if you try this shortcut after upgrading to 10.10.3, you will get a notification that you can now look up show suggestions from iTunes, App Store, movie showtimes, locations nearby, and more.

Bash Script: Fix Paused Printers In OS X

You need an administrator password to un-pause a printer in OS X.  It is possible to add a user to the lpadmin group.

sudo dseditgroup -n /Local/Default -o edit -a username lpadmin

This will give them rights to the printer, but if your users aren’t admins of their machines, this might not be something you want to open up.  This is the case for the school I work at.  My solution was to create a LaunchDaemon that would automatically detect and un-pause paused printers.

Twin Cities Mac Admins Presentation: Under Cover Of Shell (Scripting)

On April 23 at JAMF headquarters in downtown Minneapolis, I will be presenting at the April MSP Mac Admins Meetup.  My presentation will cover real-life examples of how scripting can be used.  You don’t need to know a single line of code to enjoy this presentation, but it might pique your interest to learn some!
