DNF Automatic with healthchecks.io Integration

DNF Automatic with healthchecks.io Integration

I've started getting lazier and lazier when it comes to doing SysAdmin work, but don't misunderstand me here. That just means I want to automate myself out of the picture (mostly) and just get alerts if things aren't quite right. One particular workflow I'd like to automate is patching my

Using FFMPEG and V4l2 Loopback to Play YouTube Videos as a WebCam

With the increased amount of video conferencing going on, I decided to dust off an old trick to 'spice' things up during the many video calls I am on. Things You Need * Linux : I'm using Pop_OS 20.04 for this one. * maybe other OSes too...but I'm too lazy

Using Home Assistant, Node-RED, and iOS Shortcuts to Toggle Pi-hole

Using Home Assistant, Node-RED, and iOS Shortcuts to Toggle Pi-hole

This show-and-tell post is a little different than my last few. It didn't start with a 'I wonder if I can do X' but instead a 'UGH! I'm sick of having to disable the ad blocker every time my wife shops online'. I knew automating this definitely could be done,

Porkymin Ball Z

Porkymin Ball Z

With my recent dive back into Pokemon Go, I decided to spend more time than I should on a completely silly BASH script. World, meet Porkymin Ball Z!! Try to contain your excitement as I go over the features of this groundbreaking game. * Catch the original crop of Porkymin in

Turning an Old Laptop into an IP Camera

Turning an Old Laptop into an IP Camera

The Why ...I'm cheap. I already have an old and crusty laptop doing nothing but collecting dust...and I couldn't justify the $40 to $80 bucks it would have cost to get a 'real' IP camera. The How There are two parts to this task. The first part is standing

Monitoring Infiniband Network Utilization on CentOS 7, with some bonus Zabbix bits

Monitoring Infiniband Network Utilization on CentOS 7, with some bonus Zabbix bits

I've recently had the time and the drive to dive a little deeper into Infiniband...which is a bit of an understatement considering my understanding prior to going down the 'how do I monitor this' rabbit hole consisted of compiling OpenMPI with Infiniband Support.

Using Gource to Visualize SSH Attempts...Because Why Not?

Using Gource to Visualize SSH Attempts...Because Why Not?

As with most endeavours related to the question "I wonder if I can do X?", this one started off on a day where I was very VERY bored. The question "Can I use Gource to Visualize SSH Logs?" was quickly answered when I remembered Gource can take any logs that

VirtualGL on CentOS 7 using NVIDIA Tesla GPUs

VirtualGL on CentOS 7 using NVIDIA Tesla GPUs

Rather than go over how difficult this was to accomplish, and how many hours I spent attempting, I'll just layout the steps I took to complete this task. Here is a quick example of what I was able to do with VirtualGL and X11 forwarding. According to tracepath there are

Rocket.Chat Client RPM from DEB Package

Rocket.Chat Client RPM from DEB Package

I primarily use Fedora/Cent/RHEL distributions, so I was a bit sad when I found out the desktop client for Rocket.Chat did not have a pre-packaged RPM for me to download. Not that I hold it against the team behind Rocket.Chat in the slightest. Package management is

My Bashrc

UPDATE: This is a bit dated. For one, I use ZSH with OH-MY-ZSH now. Only keeping this post alive for sentimental reasons. It was only a matter of time before I posted something like this. Seems like every other day I see a similar post on /r/linux. So, here

Gitlab

#**UPDATE** Been using the Omnibus Package of the GitLab Community Edition offered by the AWESOME team behind GitLab and upgrading is a joy now!! Ignore the rest of this blag-post. It's something past me said. Present me thinks past me is a jerk. I've been using Gitlab both personally and

MultiGrep

Situation: You need to search for multiple items that may be in a config file. Like multiple ip addresses that you are going to add to an existing config file to make sure you are not duplicating rules. You could just run multiple greps to check for each ip individually

Gitgo or: How I learned to live with VCS

UPDATE: Only keeping thins post around as a reminder of how far I've come. UPDATE: This is a bit outdated now, as I have added some features and polished up the code a bit. I will post the update after the migration to Ghost is done. UPDATE: Changed order of

Variable Variable Names in Bash

Yo dawg, I heard you like variables. So I put a variable in your variable so you can variable while you variable! Now that we've got that out of the way, time for the good stuff. I ran into this problem recently while writing a script to either take a

New Vegas RobCo Terminal Effect
