I was watching a little bit of Star Trek: The Next Generation ‘Galaxy’s Child’ last night when I noticed this look Riker gave Picard after he accidentally killed the unknown entity. I’ve seen this episode tons and never really noticed until now this nasty look Riker gave Picard. It’s priceless.
It’s been a while since I have posted to this blog. There have been a few changes in my life.
First, I received my Linux+/LPIC-1 certification in June of 2015:
And my Red Hat Certified System Administrator certification in September of 2016:
Second, my wife and I had a baby girl last March.
Needless to say, my life has been a whirlwind for the past year or so.
Going forward I may try to post more here. I’ve been on a mission recently to learn and improve my shell scripting skills. As I find helpful scripts and, hopefully, create some of my own I will try to post them here. It is my hopes to try to learn Python. Perhaps when that time comes I’ll start posting Python scripts here too.
I listen to a couple of podcast that center around the discussion of Linux over at Jupiter Broadcasting. Recently on episode #71 of the Linux Unplugged show in their post-show they discussed X2Go, a technology similar to NoMachine. This discussion was very intriguing to me because I had been searching for a thin client type of access to a Linux machine, especially at work when working from a Windows machine when I need to work on a Linux machine. This motivated me to do some research and attempt to setup my own access to a Linux machine using X2Go. This is what I setup for myself. But keep in mind that this may not be the correct way to setup an X2Go server, this is just what worked for me.
I already had an account and a cloud server with DigitalOcean so I deployed an Ubuntu 14.04 Server and setup everything this way:
1. For Ubuntu 14.04, install repositories:
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:x2go/stable
sudo apt-get update
sudo apt-get install x2goserver x2goserver-xsession
2. Install preferred Desktop Environment on the server. For Ubuntu Server 14.04, here are the steps for Mate:
sudo apt-add-repository ppa:ubuntu-mate-dev/ppa
sudo apt-add-repository ppa:ubuntu-mate-dev/trusty-mate
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install mate-desktop-environment-extras
3. Install the X2Go client on your local computer:
4. Create the session information for your connection within the X2Go client.
This is a screenshot of my connection from Windows 7 to the remote server:
If I need to, I can configure the session to go full screen. I created a couple of shell scripts on my desktop to change the resolution depending on if I am connecting from my laptop or from my laptop with a external monitor connected with a different resolution.
Here is a screenshot at full screen:
It’s been a while since the last time I posted and it looks a if I am posting here mainly to brag.
A little late, but I wanted to post that I took the VCP510 exam last month and finally passed it. I state finally because this was the second attempt at the exam. It was a difficult exam for me but now I am proud to say that I am a VCP5-DCV, VMware Certified Professional 5 – Data Center Virtualization.
For those that find this post studying for the exam, these are the tools I used to help me study:
1. The guys over at LabGuides put together some really good guides and resources to help anyone setup a nested lab. Use this site and their resources, setup a nested lab and practice, practice, practice. There’s nothing like hands-on experience to help you gain the knowledge needed to work in the field and also to help you with studying for the exam. You can find their site here:
2. VMware’s own VCP5-DCV Exam Blueprint was full of valuable information that helped me study for the exam. I had originally purchased a book titled VCP5 VMware Certified Professional on vSphere 5 Study Guide by Brian Atkinson and used it to study for my first attempt at the exam but it wasn’t enough. However, it is still a good book to use as reference material during your studying and really useful when working in a lab environment. But to really study and get fully prepared for the exam, I can’t recommend the VCP5-DCV Exam Blueprint enough.
I just came across a scenario where I needed to strip the audio out of a YouTube video file I had created in a Google Hangouts on Air recorded last night for The Unique Geek podcast. I found this post and it did exactly what I needed. Basically, I used the tool avconv via terminal but needed to install the codec necessary to convert to .mp3. The command to install the codec is this:
sudo apt-get install libavcodec-extra-53
I then used the following command to complete the conversion:
avconv -i video.mp4 -ab 192000 audio.mp3
Here’s is what was posted there:
Hmm… being intermittent like it is, and not being external, it could be a timing problem. You could try editing /etc/pulse/default.pa, search for the line:
and edit it to:
‘load-module module-udev-detect tsched=0’
If there’s any options past “detect” then just comment the line out (so you can restore it if needed) and add the new setting below it.
You’ll have to reboot to be sure the new setting takes effect. If it’s a timer/scheduling problem that should take care of it, if the problem’s with Pulse to begin with.
For those of you that have a listing on the new Google Helpouts service you know that you have the option to promote your listing via Google+, Facebook, Twitter, and YouTube. There is also the option of selecting Embed so that you can grab the HTML iframe tag code and post it on the web site of your choosing. For the free WordPress.com blogging service, this is not an option, so it was not an option for me. There are workarounds out there that will allow you to do this but some aren’t so easy. This is a workaround I figured out and I hope it helps you too.
