Scaling Script for Linux on Chromebook

This is a script for easily scaling your Chromebook running Linux (natively, not through Crouton). Put this in ~/bin/res.sh and use like so: res.sh 1280 — The common widths I would use are 1280 and 2560. You can experiment and find what works best for you though! #!/bin/bash #Original author: Travis Gibson #Modified author: Josh […]

Dual Boot Fedora on Chromebook

DO NOT treat this like a recipe! I pieced together these notes after reading through a number of different guides and poking around ChromeOS a little. I did this install over a year ago, so it’s not fresh in my memory. I’m selling my Pixel soon (after buying the new one), so I thought I’d […]

AnyConnect VPN on a Chromebook

Before you begin, you’re going to need to put your Chromebook in developer mode and install Linux via crouton. Neither of these are discussed here, but you can find more information and tutorials on how to do both with a simple Google search. There’s one such example here. The following commands are run in the […]

Triple Head with nVidia Optimus on Fedora 21 (includes Docking udev Rules for Systemd)

In this post, we’re going to look at how to setup a laptop (Lenovo T530, in this case) to utilize both the nVidia and Intel GPUs to drive a triple head or quadruple head system and to automatically configure those displays at boot, on docking, and undocking.

Resolving the infamous rdesktop error: failed to open keymap en-us

So, a simple post for today! I’ve been using rdesktop-vrdp a lot lately and I’ve been very displeased because the arrow keys, as well as del/ins/home/end/pgup/pgdown don’t work. Of course, I’ve been too busy to even bother looking into it until today, although I wish I would’ve sooner. A simple little showed the following: The […]

Running Scripts Using NetworkManager

For years now, I’ve had to run vpnc after connecting my school’s wireless. Truly, it never bothered me; however, at my new job, I need to run route after I connect to their wireless. For whatever reason, that got to me. I didn’t really want to run route when I wasn’t on their network (it […]

Distributed Commands With Ruby

Lately, I’ve been getting acquainted with Rails development at work. It’s been a pretty steep learning curve (for that matter, I guess it still is), but I’ve enjoyed it thus far. So, with my new found Ruby skills (or, I guess more-so my new found need to learn Ruby), I wrote a script that uses […]

HowTo Setup Authenticated Postfix

I recently had the experience of setting up Postfix. It works really well, in my opinion; however, setting it up wasn’t the simplest for what I wanted. But, at least it was simpler than sendmail Reading through several articles on the Internet, everyone was giving steps on how to setup postfix to handle e-mail for […]

Forefront Client Security – MOM Installation Failure

Well, I’m working on installing Forefront Client Security at my work and after configuring all of the prerequisites, nobody could figure out why it wasn’t installing. So, I setup a test machine and started playing with it. After about an hour of searching google, it seems nobody really has an answer for why MOM fails […]

Setup sendmail to use Gmail’s SMTP server

Well, I did this on Fedora 12, so I’ll be basing everything off of Fedora packages and yum; however, this should work on any distro. Things you’ll need: sendmail, sendmail-cf, cyrus-sasl Might need something more, but if so, I’ve overlooked it… The first thing we’re going to do is setup our authinfo. Do the following: […]
