Install and Configure Cobbler on Ubuntu 14.04

Thursday, November 26, 2015

Cobbler has always been my goto for provisioning bare metal servers. This is due in large part to its ability to provision CentOS, RHEL, Ubuntu, and Debian easily and quickly.

This post will cover setting up Cobbler on Ubuntu 14.04 and how to provision a server with Ubuntu Server 14.04.

Debian/Ubuntu Preseed Documentation and Working Examples

Wednesday, October 14, 2015

Debian/Ubuntu’s Preseed is not the easiest thing to understand. Having used Red Hat/CentOS Kickstart Profiles for so long, trying to setup a Preseed file for the first time was an extremely uninviting process.

Ubuntu has support for using Kickstart Profiles but it isn’t as full featured as Preseed, and I have encountered plenty of edge cases where Kickstart Profiles do not work for provisioning Ubuntu systems.

I currently spend a lot more time with Ubuntu than Red Hat or CentOS, so all I can do is try to better understand Preseed.

Create a Bootable Ubuntu USB Drive in OS X

Tuesday, October 13, 2015

Ubuntu has a great set of instructions on creating a bootable USB drive in Mac OS X, but they have an additional step I found to not be needed; there’s no need to convert the Ubuntu ISO to an IMG file. You can simply download the ISO and use dd to copy it to a USB drive.

Nostalgic Ambient Noise

Wednesday, August 26, 2015

I’m on a computer far too much. Most of the time I have music, a TV show, or a movie playing in the background. The ambient noise helps me focus. However, sometimes it’s difficult to focus with understandable conversation or singing in the background.

It’s easy to find ambient noise loops of the ocean, wind, crowds, etc., but I wanted something a bit more nostalgic.

Ambient noise from video games and sci-fi TV shows and movies provided that nostalgia.

This post will be an ever growing list of the better nostalgic ambient noise streams I have come across.

VirtualBox Commands Cheat Sheet

Monday, August 24, 2015

VirtualBox has always been the go-to piece of software to spin up virtual machines on your workstation.

More often than not, you will work with VirtualBox using its GUI. However, for those occasions where you are SSH’ing into a remote workstation running VirtualBox, it is often easier to work with it using the command line instead of forwarding X.

This post will be an ever growing list of useful VirtualBox commands.

Install, Configure, and Use minidlna on OS X Yosemite

Sunday, August 23, 2015

Sony finally released a DLNA media player for the Playstation 4 on June 16, 2015. I don’t have a lot of streamable media, but what I do have is stored on my laptop.

I have used Plex in the past, but it is overly complicated and “heavy” for my needs. I wanted a light weight DLNA server that could be daemonized and point to a media directory. minidlna turned out to be the answer.

Sort of Turn Off Safari's Two Finger Swipe Animation

Sunday, July 12, 2015

I have never liked Safari’s two finger swipe back animation. It is unnecessary and slow, and forces the previous web page to be reloaded (this particular part will change in OS X El Capitan). Most people’s internet connections will load a web page faster than the animation can complete, so it just adds unnecessary waiting to web browsing.

Wireless Laptop to Wireless Laptop Real World Throughput Benchmarks

Monday, June 22, 2015

More and more devices are becoming wireless. It isn’t unheard of for one person to be carrying three or more wireless devices on them at one time: a phone, a tablet, a laptop, and, more recently, a watch.

There are plenty of benchmarks and articles detailing the throughput achieved from a wireless device to a wired device - with a wireless router in the middle of course. This is useful to know if you’re transferring or streaming data from your laptop, phone, or tablet to a device connected via ethernet. However, most people forgo connecting anything via ethernet because connecting wirelessly is just too easy. I am much more interested in the throughput achieved from one wirelessly connected device to another wirelessly connected device.
