My Lenovo laptop thinks the pipe key is a > character

So, those that know me know I have a few laptops. I'm no stranger to technology.
Imagine my chagrin when I try piping a linux command to grep and my output comes out like so:
ps uawx > grep X
I know that the ps command thinks it is superior to grep, but seriously. WTF

Huzzah! You can use xmodmap to tell Linux what that key should actually do.
xmodmap -e "keycode 94 = backslash bar"

Want to make the scroll bars larger in Gnome + Firefox?

I did too.
I love my Dell XPS 13 because it's small, lightweight and fast. I also surprisingly enjoy using the touchscreen (much more than I thought I would before purchasing). However, because of its 13" screen and the very high resolution, it makes the scroll bars in firefox and other applications extremely tiny. Combine that with my fat fingers, finding the scroll bar became even more difficult.
Feel my pain?
Edit the file ~/.gtkrc-2.0 (create it if it doesn't already exist)

How do you install Node.JS on CentOS?

There's a ton of outdated information floating around the web on how to simply and effectively install Node.JS on CentOS, specifically one of my legacy boxes that runs 5.11. I spent about 15-20 minutes toying around with various hacky ways to do this. To save you the time, here's the easiest way I found:
Perform (as root):

curl -sL | bash -
yum install -y nodejs

Configure Postfix to use a remote SMTP relay server via alternate port

On one of my local Ubuntu workstations at home, I sometimes have the need to send mail out using mailutils/mailx inside of scripts or on the command line. I also don't necessarily want/need to set up an entire mail server on my workstation. In addition, Verizon FiOS doesn't take too kindly to this for purposes of preventing malicious activity, SPAM, etc. They actually block outbound connections on the default SMTP port (25).

Creating a local ownCloud mount point in Linux using WebDAV

ownCloud is enterprise file sync and share that is self-hosted in your data center, on your servers, using your storage. ownCloud provides Universal File Access through a single front-end to all of your disparate systems. Users can access company files on any device, anytime, from anywhere while IT can manage, control and audit file sharing activity to ensure security and compliance measures are met.
WebDAV (Web Distributed Authoring and Versioning) allows you to "mount" your ownCloud content as a local mount point on your local Linux environment.

Brightness Controls not working on Dell Inspiron Laptop with Intel Graphics

On one of my personal laptops (Dell Inspiron 17R), my attempts at using the function key combinations to change the brightness did not yield any results on Fedora 20, Linux Mint 17, or Ubuntu 14.10. The LCD brightness was stuck at "can barely see, but must conserve battery because I'm stuck on an island mode" (not a real setting, but might as well be).
The system has an integrated Intel graphics card, and if you're not sure what your system has you can check it here:
Run the command below in terminal to know what video card is used for the backlight/brightness:

Remote vulnerability in bash – patches available for CVE-2014-6271, CVE-2014-7169

Bash or the Bourne again shell, is a UNIX like shell, which is perhaps one of the most installed utilities on any Linux system. From its creation in 1980, bash has evolved from a simple terminal based command interpreter to many other fancy uses.

How to fix Dell XPS 13 Touchscreen on Fedora 20

I recently purchased a Dell XPS 13 Ultrabook with the touch screen and immediately wiped the blazing fast SSD free of all Microsoft garbage. After installing the latest Fedora 20 64 bit, I was pleased to see that most all of the hardware worked out of the box...
Except the touch screen - one of the features I was most looking forward to using in meetings, etc.
Rest assured, it's easily brought to life.
Firstly, be sure to apply all yum updates to bring your system current.

Virtualization: KVM equivalent to "vzctl enter" in OpenVZ

If you are used to using Virtuozzo or OpenVZ containers and are looking to make the switch to the full virtualization solution KVM (Kernel-based Virtual Machine), you may find one very convenient feature missing: the ability to enter into a virtual environment from the parent node.
Of course, the most popular solution used to access KVM VM is simply connecting via SSH. But what if your key gets removed or the SSH service becomes inaccessible? Rest assured, you can use this little trick to gain access directly to a root shell and manage your VM:
