Installing Google's "GO" programming language on Linux

For anyone interested in checking out the GO language under Linux, here's an article with some fairly generic instructions.

For OpenSUSE users it's much simpler.
Open a root shell and type
zypper in go
then approve the packages listed which should be "go" and "go-doc".
Enjoy.

Linux Tips & Tricks - Housekeeping with agedu

Linux Tips & Tricks - Housekeeping with agedu

If you're like most people, your computers tend to collect lots of digital piles of stuff you're hoarding for whatever reason. Sometimes it gets to be too much and it's time for a little house cleaning. One of MANY *NIX tools for this purpose is agedu (Say "age dee you"). It's like the traditional du command but with more features and a web based GUI.

Another application with similar intent is k4dirstat and it's one I use for the task of finding and deleting space hogs. It's in the package repos of most Linux distributions, but you can also find it at https://bitbucket.org/jeromerobert/k4dirstat/wiki/Home
OpenSUSE users can find it at https://software.opensuse.org/package/k4dirstat

Linux Tips & Tricks - Securing your Linux box

Linux Tips & Tricks - Securing your Linux box

You wouldn't go home from work at night and leave the windows open and the doors unlocked, so don't do the same thing with your computer.
Every computer communicates through a set of semi-standardized "ports". Like windows or doors in your home, leaving them open is an invitation to criminals, vandals, and mischief makers.
Before you can lock your windows and doors, you need to know which ones are open. Here's how.


Note: The next step is to close the open ports with your firewall, but that's another topic.

Does your Linux box's security have holes in it?

Does your Linux box's security have holes in it?

Here's a good article describing how to check.

On a personal note I would always confirm these results by running an nmap scan of your system from another computer on the same network.

Manipulating text in files is a common daily task for any sysadmin and learning to use the powerful tools available to do this can make an administrator's life vastly easier.
One of the most common and powerful tools for doing this is 'sed'.

Here's a sed tutorial to get you started.

Also note that sed has a partner 'awk' that is equally powerful in different ways. The two are often learned and used together.
