Linux is my primary operating system. I used it on the servers, desktops, laptops, netbooks, and even mobile phones since approximately 1997. I’ve tried a number of distributions over the years, and even created a couple myself. I still look around sometimes to see what others are up to. But most of my machines are running some sort of Red Hat – either a quick and easy Fedora Linux, or a stable and secure Red Hat Enterprise Server, or a cheaper CentOS alternative.
And while by now I am very comfortable in the Linux environment (both graphical and command line), I still discover a lot of new and interesting things about it. When I come across something worthy, I usually share it with the rest of the Open Software world, using this category.
“How to defend your website with ZIP bombs” has been making rounds on the Internet for the last few weeks. It’s both sad, that we have to resolve to such measures, and funny as to how tongue-in-cheek this approach is.
Whether you are going to implement it for your web host or not, it’s well worth reading, for a better understanding of what’s going on online, in places, that you are probably not looking at.
I’ve been called many a name in my days. But ‘Default Value’ is the first one for me. I’m not sure if that’s a good thing, or not so much.

Fedora 26 has been release about a month and a half ago. But I didn’t have the time to update my laptop until today. There was also nothing particularly exciting for me in this release, so there was no rush.
Here’s what I had to do today to update my laptop from Fedora 25 to Fedora 26:
# Let's get into root to save a few keystrokes sudo su - # Install all updates for Fedora 25 dnf update # Install dnf system upgrade plugin dnf install dnf-plugin-system-upgrade # Download upgrade packages for Fedora 26 dnf system-upgrade download --refresh --releasever=26 # Reboot and install Fedora 26 dnf system-upgrade reboot
If you need more help, have a look at DNF system upgrade wiki page.
The whole process took less an hour, but your mileage may vary. For me, the download itself was the slowest part. I had to pull down about 2.5 GBytes worth of packages, and given my office connection, it took about 35-40 minutes.
The installation itself took about 10-15 minutes, for which, I think, the solid-state disk (SSD) helped a lot.
One more reboot later, everything was up and running. Of all the changes pushed into this version, I think, the upgrade to PHP 7.1 is the one that affects me the most.
Graphical vi-vim Cheat Sheet and Tutorial is yet another attempt to explain and visualize Vim commands to the editor’s new users.
This is a single page describing the full vi/vim input model, the function of all keys, and all major features. You can see it as a compressed vi/vim manual.
“No more flapping. Define triggers the smart way.” is a very useful article from the Zabbix Weblog on how to setup sensible, flapping-aware triggers in Zabbix.
