There's a ton of outdated information floating around the web on how to simply and effectively install Node.JS on CentOS, specifically one of my legacy boxes that runs 5.11.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 https://rpm.nodesource.com/setup | bash -
yum install -y nodejs
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).
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.
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:
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.
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.
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:
So, I have a Dell V715w that I've had for years. I wanted to get one of my Ubuntu workstations to print to it.
What was first thought to be convenient, Dell's website actually has a Ubuntu Linux installer and drivers available for download on their website here:
In Ubuntu 11.10 and newer versions, GRUB2 will display all kernels installed on your system at boot time. If you're like me, you probably get annoyed with a lengthy list of out of date kernels to scroll through in your GRUB boot menu.
Let's be real, no one really wants to boot a kernel from last year with bugs and vulnerabilities when you have nice new shiny kernels to choose from. Thankfully, the latest versions of GRUB2 installed in Ubuntu automatically display the latest kernel and hides the older kernels that you may have installed.
