Getting Into Developer Mode On A Samsung Chromebook 2
To properly go under the hood and hack around on a Samsung Chromebook 2, you’ll need to put it into developer mode. Whether using crosh or installing Chromium or other operating systems or just doing some pretty cool stuff, you’ll need to throw the thing into developer mode. Because you have so much control you should leave developer mode off when you’re not hacking around for security purposes. Note: Before you switch back and forth, know that user accounts will be reset each time you switch. Now, to enter developer mode, we’ll first go into recovery mode, using the Escape (ESC) and Refresh (F3) buttons on the keyboard when you…

Rename a Windows 2012 Server Using PowerShell
When you are creating a bunch of Server 2012 Virtual Machines (or physical machines for that matter) it is helpful to programmatically change their names. To do so, use the Rename-Computer PowerShell cmdlet followed by the name you want the computer to have, as follows (assuming a name of 2012.krypted.com): Rename-Computer 2012.krypted.com Before you do anything else (e.g. bind to AD) you should then reboot the host, using the Restart-Computer cmdlet: Restart-Computer

The Cumulus Command Line Interface
Cumulus comes with a number of commands installed in /usr/local/Cumulus_Workgroup_Server. The assets can be in a shared directory location, such as an NFS mount mapped to /cumulus or /Volumes/Cumulus. But in the /usr/local/Cumulus_Workgroup_Server directory there are a number of commands that can be pretty useful. For example, the stop-admin, stop-cumulus, start-cumulus and start-admin commands can be used to restart the Cumulus using a simple ARD template: /usr/local/Cumulus_Workgroup_Server/stop-admin.sh /usr/local/Cumulus_Workgroup_Server/stop-cumulus.sh sleep 30 /usr/local/Cumulus_Workgroup_Server/start-cumulus.sh /usr/local/Cumulus_Workgroup_Server/start-admin.sh There are others, such as status.sh, which shows size of repository, PIDs, and the time running. The repair.sh can be used to repair the database and remove-admin.sh and remove-cumulus.sh can uninstall the admin console and cumulus servers respectively…

Core Dumps in Mac OS X
Every now and then, OS X has to drop some kids off at the pool. Usually it’s some developer that didn’t build a sanity check for every-single-possible-flippin’-thing-you-might-think-to-do-to-his/her-poor-flippin’-app-OMGYFI! And then, suddenly, out of nowhere, you get crap all over the system. Actually, as expected, Apple’s dumps are pretty well sequestered in the /cores directory. Each core file has a number appended behind it. For example, core.9901. When applications crash, they can save a lot of information about the state when they crashed into these files. For example, I have seen cached passwords in there… To disable core dumps, add the following line to /etc/sysctl.conf: kern.coredump=0 After a restart core dumps will…

2012 Penn State MacAdmins Conference
Don’t let the theft of the Paternoville sign fool ya’, State College is as safe as ever. That is, until a bunch of Mac guys descend on the Nittany Lion Shrine. Yes, it’s that time of the year again when Mac guys from around the world (and yes, all of the speakers are male) descend upon Pennsylvania State University from throughout the Big 10 and beyond to discuss the Penn State mascot, the Nittany Lion. Actually, it’s a mountain lion, so we can’t discuss it quite yet at that point, but we can talk about a slightly bigger cat: Lion. Lion deployment, scripted tools, Munki, InstaDMG, Puppet, migrations, “postPC,” PSU…
