Linux Tips & Tricks - Command Line school
For those of you old enough to remember the old phone company ads, it's time to "reach out and touch" someone. Or in this case, some files.
The touch command is another command that must be in your bag of sysadmin and user skills. While it seems like a simplistic command of little practical use, in reality it is a very powerful and useful tool.
Note: If you use an SSD with Linux, you may find touch even more useful given many distributions now disable the at-time function on SSD drives. Even if you use the preferred option of using relatime
instead of noatime in your SSD mounts, you wont have accurate at-time information for files on that drive. This can lead to circumstances where applications, scripts, or system functions may fail. In these circumstances, any kludge of a workaround will likely involve the touch command.

Linux Tips & Tricks - Using dmesg
Linux Tips & Tricks - Using dmesg
dmesg is one of the most basic Linux diagnostic and system information tools. It's also one of the first you should learn to use and should be part of your system troubleshooting toolkit.

Linux security certification process up and running
Linux security certification process up and running
The Linux community is adopting a professional certification approach to security. Individual projects can apply for certification and if they pass certain criteria and tests, they receive a badge that will let potential users know that project is following security best practices.
This is an especially great idea for corporate Linux users that require certifications for everything.
FTA:
Back in August 2015, the Linux Foundation Core Infrastructure Initiative (CII) announced a new badging effort to help open-source projects with security best practices. On May 3, the first groups to achieve the security badge were formally announced, and they include Curl, GitLab, OpenBlox, OpenSSL, Node.js, Zephyr and the Linux kernel.
To earn a badge, projects must comply with a set of security best practices as outlined in the CII Best Practices Badge GitHub repository. Most of the items are either automatically verified—for example, providing encrypted access to a repository—or obvious, such as providing good release notes, according to Dan Kohn, senior adviser to CII and the Linux Foundation...

Encrypt all the thingz! - Privacy from the Linux command line
Encrypt all the thingz! - Privacy from the Linux command line
With everyone from cyber-criminals to our own governments snooping on us these days, encryption's importance grows daily. What if you just need to encrypt a few individual files or directories?
Here are a few options you can fire up from the command line.

Linux tips and tricks - Managing your $PATH
Linux tips and tricks - Managing your $PATH
As you progress as a Linux user, expand your command line skills, and take on more complex tasks, eventually you will cross paths with $PATH (see what I did there? ;')
In fact this is true on most operating systems. The system path determines where the system looks for commands you enter. This is handy when you add new applications to the system.
Here's a basic overview of checking and changing your $PATH to suit your needs. Be careful though. This has the potential to break your system or allow malware to break free of the standard Linux security restrictions so check into and understand any changes you make here before you make them. Also note that order matters. The system checks the path locations in the order they appear in the $PATH variable. This can cause system binaries to replaced by other binaries and break functionality etc.

Make the already awesome Linux clipboard even better
Make the already awesome Linux clipboard even better
One of the things I've hated when I'm forced to work on other platforms is that most of them have terrible clipboards (I'm looking at you Windows). Linux has always had great, UNIX style, clipboard support with seamless integration, history, etc. These days however there are options above and beyond the stock clipboard. Many DE's have their own enhanced versions, and there are optional clipboard managers with enhanced features, including synced clipboards with your other devices including your Android devices!
Check out these examples.
