NEW BLOG – GITHUB PAGES AND JEKYLL

30 December 2017 by Adam Rush


NEW BLOG!

I’ve decided to make more effort sharing what I learn, so I’ve created a new
blog: https://adamrushuk.github.io


WHY?

Over the past year or so I’ve increasingly found myself on GitHub. Mainly
looking at code, but also content served up on GitHub Pages; typically sites
ending github.io.

I’ve been meaning to get back into blogging, so thought I’d give GitHub Pages a
go and see how it compares to using WordPress.

A few clicks later and I arrived on the GitHub Help pages, and noticed Jekyll
mentioned: https://help.github.com/categories/customizing-github-pages/

I’d never even heard of Jekyll before, so time for some Google-Fu!


WHAT?

Looks like Jekyll generates static content, and also integrates directly with
GitHub:

 * https://jekyllrb.com/
 * https://pages.github.com/
 * https://help.github.com/articles/using-jekyll-as-a-static-site-generator-with-github-pages/


HOW?

So now I’ve got a vague idea of what Jekyll is, I need to choose a theme and do
some testing on GitHub. The Minimal Mistakes theme looks popular and is still
being actively developed: https://github.com/mmistakes/minimal-mistakes/pulse

There’s even a great install guide that looks easy enough to
follow: https://mmistakes.github.io/minimal-mistakes/docs/quick-start-guide/


LET’S GIVE THIS A GO THEN!

Here’s the steps I took:

 1.  Forked the Minimal Mistakes theme, then renamed the repo to
     adamrushuk.github.io
 2.  Confirmed the default theme was showing as
     expected: https://adamrushuk.github.io
     
     

 3.  Cloned my new repo: git clone
     [email protected]:adamrushuk/adamrushuk.github.io.git
 4.  Added the original repo as an upstream remote: git remote add upstream
     https://github.com/mmistakes/minimal-mistakes.git
 5.  Removed the following folders and files:
     .editorconfig
     .gitattributes
     .github
     /docs
     /test
     CHANGELOG.md
     minimal-mistakes-jekyll.gemspec
     README.md
     screenshot-layouts.png
     screenshot.png
 6.  Updated information in _config.yml.
 7.  Committed all changes with an “Initial commit” message: git commit -am
     “Initial commit after fork”
 8.  Pushed the changes to GitHub: git push
 9.  After about 1 minute the changes were reflected online:
     
     
     
     

 10. Went through the awesome step-by-step guide that details the many
     configuration options
     available: https://mmistakes.github.io/minimal-mistakes/docs/configuration/

VIRTUALISATION PODCASTS – KEEPING YOUR FINGER ON THE PULSE

16 July 2016 by Adam Rush

For many years I’ve found listening to Podcasts a great way to keep up-to-date
with Virtualisation and Technology.

It all started with the VMware Communities Roundtable podcast, where I quickly
realised the commute to work didn’t have to be “dead time”.

Here’s my current list of Virtualisation and Tech podcasts:

 1.  Packet Pushers Datanauts
 2.  Speaking in Tech
 3.  In Tech We Trust Podcast
 4.  The Cloudcast (.net) – Weekly Cloud Computing Podcast
 5.  The Full Stack Journey
 6.  Virtually Speaking Podcast
 7.  The Geek Whisperers
 8.  VMware Communities Roundtable
 9.  Cloud Insiders
 10. vChat (MP3 VERSION) – The Latest in Virtualization and Cloud Computing
 11. The Data Center Insiders Podcast: Virtualization | Cloud Computing |
     Enterprise IT | VMware | EMC

The best Podcast app I’ve found to date is Overcast, as it has very useful
features including Voice Boost and Smart Speed, Playlists, and a great UI.
Oh yeah, and it’s free!

I’ve you want to quickly import the above podcasts, download and import my OPML

FIND UPGRADEABLE VSHIELD EDGES

11 June 2016 by Adam Rush

I was recently asked if there was a quick way to find out how many vShield Edges
were out-of-date and could be upgraded in a vCloud Director environment. I
didn’t know of any, so I turned to my good friend PowerCLI and came up with
this:


This file contains bidirectional Unicode text that may be interpreted or
compiled differently than what appears below. To review, open the file in an
editor that reveals hidden Unicode characters. Learn more about bidirectional
Unicode characters

# Author: Adam Rush # Created on: 2016-05-28 # Finds all upgradeable vShield
Edges and exports CSV file to Desktop $reportPath =
"$HOME\Desktop\upgradable-VSEs.csv" $report = @() Write-Host "Searching for all
vShield Edges..." -ForegroundColor Yellow $edges = Get-View -ViewType
virtualmachine -Property Name,Config -Filter
@{'Config.VAppConfig.Product[0].Name'='vShield Edge'} | % { $edge = '' | Select
'Name','Version' $edge.Name = $_.Name $edge.Version =
$_.config.vappconfig.product[0].version $report += $edge } $highestVersion =
($report | Sort version -Descending)[0].version Write-Host "Highest vShield Edge
version: $highestVersion" -ForegroundColor Yellow Write-Host "Exporting
upgradeable vShield Edges..." -ForegroundColor Yellow $upgradableVSEs = $report
| Where {$_.version -lt $highestVersion} Write-Host "Saving file to:
$reportPath" -ForegroundColor Yellow $upgradableVSEs | Export-Csv
-NoTypeInformation -UseCulture -Path $reportPath

view raw Get-Upgradeable-vShield-Edges.ps1 hosted with ❤ by GitHub

This script does assume that at least one of the vShield Edges in your
environment is up-to-date, as it looks for the highest available version
deployed and not the known latest version.

VMWARE TRAINING RESOURCES

11 June 2016 by Adam Rush

I regularly get asked where good VMware training resources are found for various
VMware products, so I thought I’d better create a page I can add links to as
find them.


VCLOUD DIRECTOR

Since I’ve had a focus on vCloud Director for the past few years, these links
are fresh in my mind:

 1. VMware has recently updated their Fundamentals course, so this is probably
    the best place to start: VMware vCloud Director Fundamentals 2016


VCLOUD NETWORKING

 1. Networking is often a tricky area for new users of vCloud Director, so here
    is a the best presentation I’ve found so far that explains how the different
    networking components fit together: https://youtu.be/EZw1UemLBoE
 2. http://www.yellow-bricks.com/2010/09/07/vcd-networking-part-1-intro/
 3. http://www.yellow-bricks.com/2010/09/09/vcd-networking-part-2-network-pools/
 4. http://www.yellow-bricks.com/2010/09/15/vcd-networking-part-3-use-case/


VCLOUD DESIGN

 1. vCloud Director Design and Scale: https://youtu.be/dzX6DgUL2hQ

I’ve just found this page which includes most of the above links and
more: http://blogs.vmware.com/vcloud/2010/09/top-resources-to-learn-about-vcloud-director.html

I’m a big fan of Pluralsight and can highly recommend these courses:

 1. https://app.pluralsight.com/library/courses/vmware-vcloud-director-essentials/table-of-contents
 2. https://app.pluralsight.com/library/courses/vmware-vcloud-director-organizations/table-of-contents

CREATE A CUSTOM VIEW IN EVENT VIEWER TO SHOW REBOOT EVENTS

15 March 2013 by Adam Rush


SCENARIO

A server reboot can explain related events and alarms triggered by monitoring
systems, so it’s always handy to check for reboots first when troubleshooting.

With this in mind, you want a quick and easy way of finding out when the server
last rebooted.


SOLUTION

You need to create a Custom View in Event Viewer, that will only show shutdown
and startup events, including reasons why the server rebooted.

Here’s the steps to create the Custom View:
